What's up guys? We are in beautiful Los Angeles. Well, at least beautiful compared to New York and Pennsylvania So we are in our hotel room. Thankfully early check-in was fine I got here like around 11 and I just wanted to either drop off my bags or check-in to the hotel because we are going to see the doctor in about an hour for the pre-op appointment The flight over here and everything not too fun.  It was bad. It was You know, it was cold on the plane So I was actually fine but like getting on the flight and then getting off the flight at LAX was just like It was bad. So I Didn't sleep at all last night late in bed till about one in the morning got up Joe from Pennsylvania to JFK, which took a few hours and then we got on a 7 a.m. Flight to get to LA It's 12 p.m. in Los Angeles now. So it's been a pretty long day I'm really happy that I didn't have a headache. I was almost I felt like I was almost getting one But you know, I thought like doing this trip and traveling for the surgery I didn't think I was in a good health position to do so, but I'm all right. I'm feeling okay. I Probably won't feel okay after the sky gadget in my eyes out tomorrow but TSA took some of my food I brought oatmeal and white bean puree in addition to like roast beef and bread They let me keep the roast beef and the bread I just wanted to have food for like a day or two before like having to eat the food in the hotel here and Everything which doesn't look that bad. It's just You know, obviously it's hard to keep like super super super clean unless you bring food yourself, but I Thought like the the white bean puree and the oatmeal counted as solid food, but they took it I could have checked a bag and kept the food in the checked bag, but I was like I don't really want to because If you guys have ever been to the airport like the bag check station like anyone can walk in and take your bag Like where they let the bags out from the flight. It's there's no security clearance Like anyone can walk in and take the luggage which I didn't like so I just wanted to keep all my bags on the flight but All that would have really done is I would have had some white bean puree I could have bought like organic bread and had the white bean puree with the meal so I Really maybe I really should have kept the white bean puree though the whole meal on the breakfast wasn't big Yeah, I skipped breakfast anyway, but that white bean puree might have might have saved me So we can just go to Whole Foods and buy a few jars of cannellini beans But uh, I'm kind of excited to see this doctor. This is a $40,000 not $40,000 it's around $30,000 about like the hotel I got to pay for a nurse Every all the expenses out here the whole trip is gonna be it's a lot of money You know the hotel is like three four hundred a night I don't know how much I'm gonna spend in the food in the restaurants. The nurse is very expensive Maybe we'll only need the nurse for a few days, but the nurse is like $50 an hour and I need 24-hour care but This was something that I was thinking doing for a really long time. I Kind of called it. I was gonna do it last year Because it's funny like all this look smaxing nonsense started after I was actually gonna get the surgery So that didn't really have much of an influence on it. I remember someone emailed me four or five years ago about this and I was like Hey, I don't know. It doesn't look like a well a well-known surgery and then A few more years past and I looked into what I thought about it Because from like from like a facial development perspective like most of my face is is is pretty good I'm pretty lucky. I'm a decent-looking guy, but my eyes have always been like, you know, sad tired droopy so This was kind of this was kind of the solution. So We'll see how it goes. I'm gonna go. I don't know if I said it already Our appointment to see the surgeon for the pre-op is in about an hour. So I'm gonna leave the hotel in about 45 minutes and I Guess I'll show you guys What I brought with me. So the hotel room could be better. I don't know what that is on the floor Probably lipstick. I don't think it's dark enough to be blood I mean like the room could be cleaner guys But the Waldorf next door is about $1100 a night and I'm not spending an extra $10,000 on this trip That's for sure. So in our suitcase These are one pair of shoes I brought and then I brought my boots. That's what I wore here I threw a bunch of billtong in my suitcase just some plain beef jerky if I need a plain protein source and then this is just Well here here all the clothes the layers I was wearing literally seven layers sweating my guts out I actually had to take off the clothes in the airport bathroom because I was sweating so much so overheated Just some underwear a few pairs of sweats, you know, I didn't really bring anything I don't expect to be going out after this procedure like I'm not gonna really be able to go to restaurants Or I think so I didn't bring anything that looked presentable So that's just some clothes and I think there might be some Wi-Fi shielding stuff in there Oh, yeah, so about half of this is just regular clothes and like here You see I brought extra pairs of Wi-Fi shielding clothing We had a layer of the long-sleeve sweats and pants on but I'm wearing I'm always wearing the Wi-Fi shielding clothing Here I just bought the supplements that I need for this week things to reduce my copper molybdenum zinc and Vitamin B1 and then we have some mastic and some charcoal So these are like the supplements that I'm gonna have with every meal and then if I'm gonna go out to a restaurant I actually bought some Little plastic baggies with me so I can bring the pills with me to the restaurant Not have to carry all this with me Passport car keys, that's the medication for the surgery the doctor gave me. I might not take probably not gonna take the antibiotics I brought some water key for grains the TSA did not seize the water key for grains which Minor might not be a lifesaver. I don't really I'm not really sure if I need them I was gonna use that instead of the antibiotics Over here, we just have an apple and some bread I ate the roast beef already, so maybe I should have brought some extra, but This is the Icelandic water from the airport. I'm gonna go to I'll talk about that in a second and this is just my laptop that I've never really used Lenovo Legion with the Leopold keyboard and ambidextrous I mean I bought this a while ago because I thought I was gonna travel more and stuff, but I guess it comes to use now and And I'll be able to use it also if I get a second location as the main computer I bought a grounding rod a grounding plug-in for the wall and you probably shouldn't use this more than an hour or two because of The high non-native frequencies, but it's better to do it one hour day than not at all And then here I just have a bunch of emf protective stuff I wore like two hoods when I was in the when I was on the plane I had two hoods on my head and the hat at all times and I just have some bandanas and some hoods here and some EMF head protection for when I'm gonna sleep. Yeah, I don't really want this vlog to be too long I want it to be focused on the surgery and like 20 minutes or less, you know, I don't want to show like all the lifestyle stuff I'm just giving you guys an idea of what I needed to travel mostly emf protective clothing a small amount of food to supplements We're gonna go having more in Los Angeles guys It's basically like New York where you should have access to everything So I'm gonna stop by Whole Foods and see if there's anything I want to pick up Main the main thing I got to get Whole Foods is if I got to get a few cases of glass bottles of water and We're gonna go to Target and get a high-powered fan if the hotel doesn't have one just so I can blow air on my face when I'm sleeping with because of the It's hard to breathe. You can't breathe in the head cover without air flow Yeah, so we're gonna go to the doctor's appointment. We're gonna go to Whole Foods and Target I'm gonna do that. Maybe I can convince an uber to keep his stuff in the car and pay an extra Yeah, this this We'll go see the doctor and Then we'll talk about the the surgery after we see him. Alright guys. I'm back in the hotel I got some sparkling water. We did the iodine nasal flush They didn't have the regular flat water and if you guys ever put sparkling water into your nose You'll know it's not a good idea like for some reason the carbonation it like completely clear clears it out It's really really like accurate which might be a good thing or a bad thing But I'm just doing that because you know I'm interacting with a lot of people. I that usually clears up my headache, but We went to Whole Foods went to Target to get the fan after we saw the doctor Nice guy talks really sweet Procedure originally was like he was around 30,000 for what he wanted to do Which is a lot of procedures It's a first is an orbital decompression where they take out some bone behind the eye to let the eyes get more deep set and further back second is a Rim an orbital rim plant down here for the shallowness third is a lower eyelid lift a little bit called lower eyelid Retraction and the fourth is the upper eyelid photosis repair. So originally he was only gonna do One-stage decompression. He might do two stages, which is a little further back and instead of just doing the the photosis The upper eyelid on the right eye. He might do it on the left eye, too. So Basically like the way my eyes are I have pretty much like the worst combination of features possible That made me eligible for everything he offered like a Lot of the other patients that see him they don't have like You know, they don't have the eyes tilted They usually have one of the three or four problems, maybe two in my case. I'm four for four. So I think there's another $8,000 added on to that so Whatever my my business credit card has a very high limit That's the only way I was able to afford this guys. I like I wanted to get myself a birthday present this year for going through so much and I just got a business line of credit on one of my LLCs And I'm just gonna pay it off For like a year. So That's that we got everything ready It's about 3 30 p.m. Right now And my head is feeling better and my head's clearing up So I'm gonna just do my emails do a little work I'm probably gonna relax for an hour or two just Hydrate relax and we're gonna go to I think don't first goes and get a steak and potatoes maybe because I worked A del Frisco's in New York and it's a little nostalgic and it's a steak house That's close by so we'll go to Del Frisco's for dinner And then we'll come back to the hotel and get to bed early and just rest until the morning I just want to get my emails and stuff done because He's telling me I'm not gonna be able to really see or do a lot of computer work for four or five days And it's you know, it's it's Wednesday now So if I my eyes are gonna be completely closed for like two days And then Saturday Sunday Sunday, I might be able to start seeing and maybe doing some computer work He said but I don't know so I'm just gonna get some stuff set up on my businesses We're telling people like I'm out of the office until next weekend until middle of next week and He also said that So then I'm gonna see him a week from the surgery tomorrow next Thursday And then that should be it my flights on Saturday morning and I paid for the hotel But am I I'll see how I feel I might just move the flight up because I'd rather like You know waste one or two nights of hotel expense and just get home a day or two earlier Because it's not like I can really go out and have fun with the way my face is gonna look Maybe we I'll have to see how I feel if my vision isn't a hundred percent I might stay because I have to drive my car back from the airport when I get to New York, so That might be a problem, but we'll see we'll see we'll see how it is All right guys, I'm lying here in my hotel room. I got all my emf stuff on I got a fan blowing in my face so I can breathe I Forgot my deodorant, which is a little important. I Also forgot my emf meter, which would help me tell if this is effective enough or not, but I'm feeling a little better Unfortunately, I had to take three motrin so far today. I'd be profan Which is like the only pain medication that doesn't mess up my liver because my head was starting to hurt. I went to the Restaurant here. I was gonna go to Del Frisco's but I decided to check the hotel restaurant to see like okay If I have to order room service in here for the next like a few days Like is that what I'm gonna do and the food's like really bad and really overpriced So I think there's a shake shack near here. I think I'm honestly just gonna door-dash playing hamburgers from Shake Shack and have it with some beans One option I had when coming out there was there was like a care facility I could have stayed in which was like about the same as I'm paying this nurse per night like over a thousand dollars And they have food inside and asked them about the food and dietary restrictions and stuff. So I'm feeling like that would have been the better option now Because the reason I stayed in this hotel was because I thought the food options would be better And I'd be able to like get my own food and stuff but I Don't know that's too late now. So it's whatever so I'm gonna try to relax for a few hours It's only like 7 p.m. and the surgeries at like 7 in the morning. So it's not like I'm gonna be able to sleep for 12 hours straight, but that's That seems like what the food situation is gonna be unfortunately If I had to do things over again, I would have probably got What was I supposed to do rent an Airbnb get here a day early and like prep food like it's ridiculous I think playing hamburgers from Shake Shack are gonna be fine Because I can get like They have like a really crappy steak sandwich here That is like 30 bucks.  It's Kind of crazy. All right, we've actually researched our options. The problem with Shake Shack is the potato buns They use are with enriched fortified flour and I think that might mess up my sleep and I'm looking at all of these like steakhouse places around here and It's they're all like I'm not gonna pay for like steak twice a day like 70 bucks. Like that's crazy Bro Wendy's this sounds silly Wendy's uses fresh beef. It's only beef and they have baked potatoes.  I don't feel too But I can see like blurry out of my right eye and We're gonna go on the street and see if we can get some fentanyl because this guy won't give me more I'm probably gonna oh, yeah, so let me see how bad it's swollen Looks like the same as yesterday, right? Is it bright enough in here? All right. I'm pretty sure we're rolling. I'm basically blind, so I really It took me about five minutes just to click the camera icon on my phone and click record I was gonna wait for this girl to do it for me and help me, but I Don't know when she's gonna be back. So We are at It's called Zen healing retreat. I think it's in Bel Air. It's it's the same company that I was hiring the Nurses from to come to my hotel and I think I told you guys like the reason I actually didn't just come here in the first place was because like I Checked the Google Maps out of bad time And I thought it was like 45 minutes away So I went I opted for the hotel which was closer, but it's actually 10 minutes away with like without bad traffic So before I explain why we switched from the hotel to here I'll explain How the day of surgery went so Today is the Fright it's Friday morning right now very early Friday morning. We left the hotel at seven in the morning to come here That video I just played before this was probably an hour or two ago So first day post-op Actually felt okay enough the first day to probably film but Yeah, I'm gonna film a vlog real quick you want to just give me five minutes Yeah, hold on. Can you actually come over here and make sure I'm rolling? Because I'm not sure I think I think I I think I was able to decipher that the camera is rolling, but I'm not sure Am I rolling in Okay, we're good just double-checking So the surgery was actually in this guy's office Originally, I thought it was gonna be in a hospital But he did it, you know in his office. So I got there around 645 and they were like on California time So they didn't get there till like seven. So that's when I got let in I Think I was with the nurse and changing into the gown for about 15 minutes Then we went right over to the surgery room We're a nice Asian doctor is anesthesiologist Lays me down in the bed starts talking and I was like I mean this it was deja vu for me because I know like they talk to you and in about two minutes You're waking up from surgery because You're just out like the anesthesiologist asked you a few simple questions to the dude and then he puts you out so When you when you come out of anesthesia You You like don't you still don't remember it for like an hour or two So apparently I was saying some very colorful things to the doctors. I got to get an official list Before reporting back on that one.  She took took me up to We went up to the room and then basically I Just I just laid in bed On Percocet in my Wi-Fi cocoon From like what time did that go leave from like 12 to 7 that nurse was Taking care of me and they swapped out another nurse at night The food I had she picked me up I had that girl She actually picked me up to the plane Wendy's hamburger and the baked potato Which is like the only food I could find that fit my diet without messing up my stomach We took a lot of masticum we took some b1 We took some charcoal we took some motrin hopefully my stomach doesn't start bleeding because My bloodstream is half motrin right now, but We actually didn't take Percocet today. We took three Percocets yesterday. I think maybe only two But I don't Percocet is oxycodone and Tylenol acetaminophen So I don't want to take it because I know that's bad for my liver, but I Had to take two or three just to stop the initial pain and feel better And I figured out part of the reason my head was hurting was like My jaw was so tense and my jaw still hurts I'm guessing like when I was under anesthesia and the surgery like I'm guessing I was clenching my My mouth and pain like biting down really hard because my jaw muscles really hurt more almost more than the rest of my face But yeah, I know I didn't really have any Pain in my face. I just had like there's like a mild pressure and I mean I I've been getting headaches lately just from my liver damage, so It's kind of like a mish mush of Whether it's from the surgery or not, but the Motrin has been keeping it in check and Very nice young girl swapped out for the nurse Last night around seven. I think I don't remember exactly but That girl was that girl stayed with me through the night and overnight She basically helped me eat dinner my second meal, which was The first meal. I just had a plain hamburger patty and a baked potato for Wendy's The second meal I had the plain hamburger patty with my homemade roll some cannellini beans in the jar and Had an apple with some mastic gum and be one The first night before the surgery, I think I slept four or five hours in that hotel room Then the day During the day after the surgery, I think I might have dozed off for an hour or two And then last night I think I got two or three hours of sleep, but I was basically just laying in bed awake The first nurse the first nurse who's like who's helped me was like who's like Partial owner of the company mentioned they have like an oxygen machine and like I was like, okay You give it to me and she brought us to the hotel and we have it here now Which really helped like I was feeling okay But then with the oxygen machine I felt good my headache like completely went away and I was feeling good Because the co2 levels in LA in any city are kind of high. So Dude, I was I wanted to take a video of it.  So I was like in a zero Wi-Fi environment with with oxygen so I was feeling okay, but I Would imagine like I probably I wouldn't be surprised out of all the people that I've ever gotten that procedure with that doctor that I feel the best out of all them because and suffer the least because of My knowledge of the radiation and the oxygen because without that.  My eyes never really swelled shut But he put a contact a Blurry contact in my eye to protect the eye from the stitches now I can't see through that contact So this guy wasn't and and he's taking that contact off Thursday of next week so After I put put two and two I only hired the nurses until Sunday, you know three more days But he's telling me this contact is staying in my until Thursday. So like okay, what do you mean? I'm not gonna be able to see until Thursday. So I Mean I'm paying I think I was paying the nerve I think the nurse was like 12 or 1300 a night and they have to care facilities 1800 and it's way better and I didn't realize it was that close and it's more relaxing and I'm I'm grounded out here At least I think I'm grounded. I have no clue right what the scenery is here again guys. I'm actually I'm not blind blind like the way my vision is now I can see there's green grass here It looks like a tree there, but like I don't know like What the scenery is like is there a highway there? I don't know how well this is grounded But the point is I think I'm grounded. It's nice and relaxed out here. The emf is definitely gonna be much lower I don't think the air quality is that much better. Maybe it's a little better but I Figured dude. I mean if I'm I'm gonna have to pay I'm gonna have to get a nurse until throughout the whole next week anyway, so If I'm gonna pay if the only reason I got the hotel was because I thought I would only need the nurse for a few days But it's whatever, you know That surgery was like Almost 40,000 and then They have to care on everything else. Hey, it's not she not she but When you're you know, these other people they take care of and I was speaking to these nurses these people were not and I know I use the word blind like I'm not blind guys. I just can't see right now because of the surgery like blind might not be the correct term, but I I Literally can't do anything on my own You know, I mean I can get up and find the bathroom and use it I can get a bottle of water and drink it by like seeing where stuff is and I literally cannot decipher anything So, you know, I need to I needed to leave the hotel and and have someone help me and do everything for me So that's why we came here. So that's gonna be the game plan Yeah, I mean this is gonna suck if I literally can't see until until until Thursday Maybe as I open my eyes and and I put something maybe if I open my eyes and put some as my eyes open more and I put Some eye drops in Maybe I'll be able to see Before and like I'll be able to I'm just hoping I'll be able to maybe check my texts and emails before Thursday But it's not the end of the world, you know, it's only a week The main thing I'm worried about now is If I'm gonna feel good enough at the end of next week to fly I mean, I should feel good enough to fly home, but I don't know if I'm gonna be able to Who knows if I'll be able to drive my car home from the airport. We'll see about that Am I even in frame? Bro, was I not in frame this whole time?  It's over with you know, we made it out here. We surgeries done now it's just Another week or so and then we're back Back in New York, I guess Yeah, I'm happy it's over with but like I Have no clue what I look like or what I'm gonna look like until you know, I can see so I Look, I'm a little curious, but Thankfully, I don't you know, I don't feel bad. You know, I feel pretty good physically My head doesn't hurt that much Yeah, I mean to be fair the we got some very invasive procedures This doctor doesn't usually most people don't usually get those procedures with that doctor so My stomachs actually start to hurt a little bit. Oh Usually my bladder is fried like I have to go to the bathroom every half hour for some reason but The prednisone they gave me yesterday was like it like blocked up my kidneys So I like was barely peeing all day and then suddenly at night.  I didn't take I didn't take the antibiotic. They gave me I Did take the Percocet they gave me methylprednisone and I think it's called the mineral corticoid I forgot what I think it's produced by the adrenals.  I don't know if there's any towers I don't know what the radiation is, but it should be good. I mean I'm I'm blind, but this place is like Beautiful house in Bel Air Yeah, then I got to go to Whole Foods. This girl cooked me the nurse cooked me steak bread beans, so we're back on Perfect diet. No tummy troubles. We got Everything here key for grains mastic some Motrin just in case just to reduce the swelling and Just a few other things here. Chocos ink molybdenum Mountain Valley water Now I'm not spending much more money being here because the nerd hiring a nurse out here in LA is already crazy expensive What would save you money is? Not getting surgery Now I was unlike I think I said it in this video already, but I'm in like a unique scenario where I Was eligible for like five different procedures that can be done to your eyes or normally people would only need one or two of them but um If you had someone that could like cook for you and take care of you You'd say like, you know, you'd save the $15,000, but And I think I said it in the past time and it's like I can't blame the doctor for not telling me I'm gonna be blind for a week But you know if you go out here by yourself and you can't see for a week Like that type of medical care when it's not covered by insurance insanely expensive insanely expensive, so You know have to be done.   Maybe we'll get to talk to the doctor and Just relax All right guys second meal similar. We got the steak cooked a little rare Instead of just plain bread. I kind of toasted with a little butter on it, which is way better. We got some beans So this is basically gonna be my meal for the next week.  They're pretty good Why did I start work on it? I was gonna say something.  You want to be like in like a suburban reasonably isolated area Just because of the EMF stuff and then The air quality hopefully you can get an oxygen machine too.   I'm I'm physically fine like Like I feel like my body feels fine. I'm good. I can move that and stuff, but my vision is just It's actually a little better now, but like I can't really see much and despite me making all the blind jokes I'm basically like it's just like imagine like Your vision just really blurry almost it's almost like you put Vaseline in your eyes or something and like everything's just like You can't really make things out. You have to get up really close, but we'll see We'll see it's like Saturday morning 7 a.m. The next day and thankfully like I feel really physically good Like I just can't sleep like I Haven't really been having headaches If my eyes start like hurting, you know, I just take a percocet every six or seven hours And You know, I'll have like my I'll have my I'm eating I'm just eating right now So I have my hood down but like I'll have the the Wi-Fi shielding hood on and like the headnets and that oxygen machine helps a lot because Like normally I wouldn't need the oxygen machine, but like if I put the tube in the headnet I can like Sleep easily with them with because the oxygen is coming directly into the headnet So it's like kind of like a weird setup or like I don't have to worry about Asphyxiating myself with the head cover But the reason I'm filming now to give you guys an update is like I'm having a difficult time I'm assuming with the sleep Like again, since I feel good and the percocet's helping like I'm okay, but I Wasn't sleep remember I wasn't sleeping before I got out here. I was having issues with the B1 and the copper Now if my blood copper levels are high There's two possible like there's two possibilities one We have to just not do anything eat as much food as possible and hopefully The blood copper levels lower or two Which I think might have I might have to take zinc and molybdenum with every meal But I was doing that yesterday My bladder felt better, but I still didn't sleep So it's possible that the zinc and molybdenum are Are pulling more tissue copper out and elevating the blood levels Because zinc zinc directly pulls out and binds to copper molybdenum line binds to copper in the digestive system and increases urinary excretion of copper But I don't know if molybdenum would necessarily directly lower blood copper I haven't I didn't read enough into the literature to figure it out, but I'm guessing zinc can be a bit aggravating so I probably shouldn't take it and that molybdenum Should just work, but the first day when I took molybdenum on its own it didn't seem to help much So I'm not really sure. I'm just gonna play it safe today and see if I sleep Worst case scenario if we don't sleep We'll try a higher dose of B1 tomorrow and if that doesn't do anything You know, maybe we won't do that, but If like I don't think my sleep is still fucked up for like another day or two then I'll move to the under the other end of the spectrum and try to increase the dose of zinc and molybdenum Because I'm not sleeping anyway like it's not gonna get much worse but No, thankfully we're more in here and I Was spending the same amount of money anyway because I was I was paid for the nurse and the hotel so This is the same price and EMF is definitely lower. It's more relaxing more importantly, you know, they're they're cooking them up The pain isn't that bad like If I just laid in bed without any pain meds and just laid there Like I'd be uncomfortable, but I'd probably be fine But as soon as like I move or open my eyes or see any lie and I might be repeating myself, but like Well, I know I know is Like talking about like the doctor kind of you know wasn't a hundred percent transparent about The recovery but He didn't he didn't mention stitches what he failed to put into a coherent sentence was I'm going to stitch your eyes open like a horror movie because I cannot I think I might have said this yesterday.  We got Saturday to go through some day one day Tuesday I got five. I got it.  I'm gonna go crazy. Hopefully it gets better But I don't know because if my eyes are stitched in this position and there's a Contact lens on my eye, which is foggy. I don't know If I'm gonna be able to see at all. It's not that big of a deal I was you know, I was hoping I was gonna be able to check my emails and see how my business is doing on Monday or Tuesday But worst case scenario just has to wait till Thursday when he takes them off And then once I have access to my computer like it's not like my flights on Saturday But it's not that they give a deal if I have to stay in LA a little longer because as long as like I have computer access And stuff, I might not maybe I'll film like Sunday or Monday. I don't know But we're just gonna be like Money in bed eating the same meal. Oh I gotta remember to ask the nurse We got to see if the hotel got my because I sent water key for to myself Which might help me sleep. I Have water key for grains, but like for some reason those don't Sometimes those don't help me really sleep.  It all goes it all goes away.  It's already done Whatever All right. I'll see you guys tomorrow. I hope I was recording that last clip. I think I checked um So that last clip was just an update of me Uh talking about how I felt into some random stuff but All I remembered I want to talk about like this procedure in general in relevance to facial development.  It's going to bulge out So, you know, usually when someone has like a narrow skull or like um Poor facial development the the eyes start bulging out, which is kind of what I had so What they do is that, you know, they go in and just remove some of the bone and stuff They they hollow it out which kind of is like almost replicating like having a wider Area in there.  So it sounds dumb, but like They don't have a they don't have a large nose. They have a small face It's on again.   I'm just I'm being dramatic. Trust the process. We'll see how it looks into um It's sunday Physically, I felt like a hundred percent honestly like I want to exercise because like I like I haven't been moving and stuff and like I have a lot of energy from laying in bed the whole time but like visually I was patting my eye with the Like a damp towel this morning the left contact accidentally came out, which isn't a big deal.  There's just checked my messages to make sure that nothing fucking went wrong um So we should be in the clear like I don't really have like I don't like the emails to answer the customer service like that can wait until the end of the week I'm not worried about it But yeah, no like vision-wise like Since that contacts out like my vision is a lot clearer in my left eye, but it's still really blurry that like Like I couldn't actually Cook food or do stuff on my own still like I'd be it'd be too difficult to do it. So Yeah, I don't think we're gonna be I mean it doesn't really matter I was just hoping um I was hoping that like Maybe I'd get to go out one night before my fly-on Saturday or like maybe I can film a restaurant vlog one night But I don't hey if it doesn't happen. It doesn't happen I I highly doubt I will well I mean I have to feel good enough to drive by Thursday Friday because when we get back to New York the car is to the airport So yeah, if my like if my liver wasn't made of paper mache at this point We've probably gone a lot smoother Like I think my liver resembles a fried pork chop more than a healthy human liver Oh, we did try I consulted my inner nutrition genius and we decided to To take the zinc and molybdenum did help me sleep. So I was worried that it might kill it more copper, but we ended up needing it. So We're feeling better. We're feeling okay and It's only It's only day Three it's because the surgery was on Thursday Friday Saturday today's like middle of the day Sunday I just ate breakfast I need to I need to just like shower or bathe or something because I feel like I feel kind of gross Right now.  You guys want a closer look how do my eyes look?      I think that's everything. Yeah, I don't remember I think I said it at the beginning of the vlog like what actual procedures he did but um The doctor's office did try to call me Uh, I think right like after the surgery or friday or something But like they called this number and I had my phone on airplane mode. So I wasn't able to pick up Um, still I just I mean, I'm assuming everything well I just wanted to ask the doctor like hey, you know, how'd the surgery go? What what'd you do in there exactly? but what he you know was telling me he was going to do was the the double wall orbital decompression so He goes in behind the eye socket into the orbital area and he basically grinds out bone To to let the eyes go back So that was one procedure another procedure was Infra orbital rim implant which puts just like A basically a piece of silicone under the eye To to get rid of like the negative can of tilt And then he does a lower eyelid retraction Which moves the lower eyelid. So again first procedure orbital decompression Second procedure is the infra orbital rim implant Third procedure is the lower eyelid retraction and then What are we on three and then there's fourth procedure is The upper eyelid ptosis Which is like is for jupy upper eyelid So like my right upper eyelid Was a little droopy like it was asymmetrical to the left one I didn't really care that much but like my eyelids were low in general So what he actually ended up doing was we did both of them We we raised the right one more and then the left one we raised a little bit. So I'm excited to see what I'm gonna end up looking like but I'm just like impatient Losing my mind here. I think I want to rest my eyes for at least Another day or two because if I like squint and look at the phone Like I can kind of decipher like the emails and the messages, but it's very very difficult So I don't want to like strain my eyes or anything right now. So I'm going to wait until like Tuesday or Wednesday and then maybe if we can Do some work then if not, he's going to take the contacts and stitches out Thursday.   Thankfully like I found this place because I have I have my emf hood, right? So I'm like I put the emf hood on Which blocks some radiation and then I have like I have the head covers that I put on to sleep, you know, I put them like I put them on my head right I put them on my head sometimes I just I just keep them like this so I can breathe out my mouth, but What's what's really special is they have they let me use the I got the oxygen machine here so like Most of the time I don't use the oxygen but like If I'm getting a little bit of a headache or like I'm feeling a little nauseous The oxygen makes it like go away immediately. So I'm not really wearing this but I'm like if I have the head cover on for a few hours and I put the oxygen in my nose like I can breathe easily with the head cover on and Like just in general it's like a low radiation area and I can like I mean I have my like Grounding thing plugged into the wall here, which I couldn't do in the hotel And also they have like a little plot of grass outside.  It's like it's good to go. It's fine Which I normally wouldn't be able to do We kind of lucked out But I yeah, most people like I mean this is It just seems like crazy in general like all these nurses I spoke to like I'm like I'm the first patient they treated that was actually like Not I mean I'm not technically blind but like the vision impairment thing So it's definitely not a common thing to have to deal with the overall the pain is pretty much gone My nose is dripping a bit.     I'm gonna try to find that email to see when I got the genius idea to get my eyes gushed up It was a summer of last year So june of 2022 was when I was uh interested in getting this procedure and then like He told me about like The vision stuff and the recovery and I like it like turned me off a bit And I'm like over the next year I thought about it a lot if I wanted to get it done or not and and eventually like Towards the middle of this year. I convinced myself to do it. So as I said earlier like this is not like This is not like um This wasn't like an impulse thing, you know, I thought about it for almost two years and then scheduled the surgery And I felt good about it. So I was like whatever, you know Either way, it's gonna look better than it's gonna look better after than before All right guys, it's monday around noon. I'm in this really nice house in bel-air I feel like i'm working at a san francisco tech startup in some billionaire's house because i'm like on my laptop Probably honestly, I shouldn't be doing this right now. I should probably be resting my eyes um, I can Somewhat decide for my emails. It's difficult. It's taking me like maybe Three to four probably longer than three more than three to four times longer than normal to just like kind of read them and decide for them But um, I'm just going to try to Get all my emails settled So that Then I can take a rest for a few days the rest of the weekend and won't have to worry about any business stuff we had uh a good thing I checked because the The foam containers for the eggs showed up and it was going to get held in the port if I didn't respond to the email So thankfully I saw that I was able to respond to that But uh, nothing nothing crazy happened this week. Nothing crazy happened, which is the main good thing with the business, but Overall i'm feeling okay I'm not sure if the mild tension in my head is from the surgery or it's from Incorporating dairy back into my diet. I haven't had a little I'm gonna have a little butter here in there So I'm just going to take a motrin I've been taking motrin consistently. I'm taking motrin and see if that Helps at all because We went to the hotel and they did have They did have my water key for shipment. I dragged this which might not have been a good idea Wasn't that fermented wasn't that carbonated so maybe maybe the water key for mess me up a little bit too And this meal, but I'm just hoping it's going to help me sleep better. I don't know we'll see We'll see how today goes But I feel I feel okay. I don't feel that bad, which is all that matters Yeah, I may probably kind of look the same. It's just a little as long as a little better What's nice is like I'm basically feel like i'm crying the whole time My eyes are so moist that they don't dry out and hurt that much But I literally have like water streaming down my eyes out of my nose It could be worse But i'm gonna do some work for a little bit and then probably just relax the rest of the day and hopefully maybe Try to get some sleep because we didn't sleep that well last night It's only monday and We're gonna be seeing The surgeon thursday morning. He's gonna remove the stitches and the contact and everything He said I could fly back He said I could move my flight up to thursday and fly back that day, but I have a feeling like I'm I'm probably better off staying until my scheduled flight on saturday just Because I have a feeling like if I go back thursday morning to new york like I don't I it's probably not safe to drive with how my vision is going to be, but we'll see All right guys, it's tuesday. I'm always wearing this hood to minimize the emf These are on myflashily.com.  They got a full shower That's like the toilet area Double sinks just really really expensive house. This is like a house. I would have if I had a rich russian girlfriend She would have me stay here and tie me up to the bed There's like a balcony here that overlooks the front drive, which isn't really much of a view but um I felt pretty physically good since the first day and My stomach was a little wonky from the hotel food and the wendys, but now We got the organic food And we're feeling good. I'm feeling okay Still taking motrin fairly consistently Uh The the pain in the eyes and the irritation is there and there is a little bit of like light pressure in my head But what's really strange is I'm curious if since he did the orbital decompression And remove some tissue from behind my eyes If that's going to potentially fix my migraine headaches as like a side effect because I've heard like thyroid eye disease patients can get Migraine headaches and since my eyes were slightly bulging maybe that had something to do with my headaches I don't know just a hunch. I guess we'll see like over the next few months After I've recovered from this like if I never get headaches again, then I know that it did something but Called the doctor's office up. We spoke to him yesterday. He said everything went pretty well We'll speak to him again on uh on thursday when we go to get the stitches removed I'll get more details. Thursday will probably be the last day of this vlog I'm just gonna Because I mean how long am I going to film recovery and do updates for you know The the two week point is supposed to be when Like the swelling and everything has subsided. So what we'll probably do is Like thursday here will be the last like Part of the vlog and then maybe I'll film one more day at the two week point and then we'll post the vlog So it'll be like daily updates from days one through seven. I don't know. We'll see And then maybe the the second week. I won't do updates as frequently Because we're supposed to be back in new york on saturday which is like day 10 Or most of the swelling would still have not subsided But uh, my stomach's been pretty good. We got the meals consistently Sleep has been okay. I've been sleeping a few hours a night not the best But you know four or five hours a night is better than I usually do Uh, the zinc supplementing helped We've been doing some b1 as well The food's good I'm feeling okay stomach my stomach is it feels a little I get a little stomach pain, but that might be because I've gone through like half a bottle of motrin this week Um, so it's hard to say uh Yeah, my eyes are Just they just feel irritated But I'm just I've just been doing some work on my computer Catching up on emails and everything. We're pretty much all caught up. But just It's it's so much every day like guys I used to I used to answer emails and do customer service and stuff on my computer for at least an hour to a day So even I mean we only missed four or five days of work and I've been on my computer all day yesterday and today so Um, it's a lot a lot more than I usually have to do in one session Because as usual business is hemorrhaging money, but go figure Could be worse But uh Yeah, that's really that's really the only update for today and doing more and more Doing update tomorrow wednesday and then do a do an update after seeing the surgeon on thursday All right guys, it's wednesday Uh, we're getting the stitches out tomorrow morning. So i'm looking forward to that i'm guessing it's gonna Make my eyes look somewhat more normal Because I think they're like kind of sewn shut right now, which is pretty wild I'm feeling okay Bad sleep last night Had an extra purpose that they gave me because This doctor wouldn't give me any more pain meds, which is ridiculous because I took enough motrin to burn a hole in my stomach And it didn't make me feel any better And I I can't take Tylenol because I think that's even worse for your liver Tylenol gives me bad headaches.    Like what am I gonna do?   We we switched we switched the diet up. No more butter. No more cream. So I'm just gonna do Steak bread and we made a wiping puree They actually what what what saved me here was even though I'm spending crazy money here They have a full kitchen.  I couldn't make my food to be a nightmare So like I was able to make the wiping puree. We have the steaks. We have the diet. Everything should be good So eight this morning. I'm feeling okay What's very strange to me is And I I'm not sure what it is. I might have said this already, but My hydration cues have been off Back when I was in pa I was used to pa in new york I would always be thirsty and chugging water because I was thirsty but my actual thirst Hasn't I have to force myself to drink because I don't get thirsty And my bladder has been much better. Usually I have to go to the bathroom. I but I haven't really been having to go That could be the high calcium mountain valley water That i'm drinking instead of the fugee low mineral water Or it could be something else I don't know, but uh Yeah, I'm still feeling pretty good physically It's just the the stitch on this I started stinging So that kind of hurts a little bit All right guys, it's thursday One week after the surgery doctor took the stitches out I don't like as much of an abomination, but Still swollen eyes are swollen I thought I was gonna look like somewhat normal in two weeks with a doctor said It might take like a month or two But based on what I look like now Like I'm pretty sure it was the right decision. I think I'm gonna look better overall in the end Uh, the only thing I was worried about was like I already had a long face so I wasn't sure if like Even if like Raising the lower eyelid a little bit made my face a little longer like I still think I'll look better overall in the end anyway But uh, I still can't touch or really wash my eyes for another week So it was one week No touching or washing no water at all And now it's another week two weeks total of no um No washing the eyes no water at all, but um the nurse here separated my eyelashes with a q-tip So I can kind of see now I can see pretty well And I look a little normal without the pads and stuff on my face so we're gonna Be just relaxed last day here tomorrow um I can't exactly wipe this blood and cook off my eyes. So I don't think I will be going to a restaurant while in LA unfortunately Um My mom was a little sad. She hasn't seen me in a little while. So First thing I do when I get back to the airport.  So after he took the stitches out now there's kind of like no real pain at all. I just feel like this swelling and um, my little maybe mild stinging mild discomfort But I think I'll be fine to drive.  See what I look like But I don't know.  So it's fucking whatever The one thing you can't change Let me show you guys in the mirror Here I actually look pretty good I actually look pretty good here at least compared to uh, oh I asked the doctor, um, if he gave me a neutral or positive cantile tilt I was hoping he did neutral, but he actually did positive. So I'm it's kind of crazy because I'm going from like an extremely negative cantile tilt to a positive one I thought he was just gonna leave it neutral, but the uh, the ride.  I'm glad we got this over with Uh, you know something I was like, you know, I'm gonna regret it if I don't do it But I think um, I'm just trying to be like if I'm going to film another day for this uh, for the surgery vlogger If I want to post it sooner than later because If it's thursday now I'm back in new york on saturday I announced that like we had the surgery with some I'm going to do some joke shorts that are really fun I'm gonna pretend I got beat up. You get it would have been posted already by the time this goes up I joked like that I got beat up by a vegan girl or something Um, so those are the shorts about how I'm gonna announce the surgery and then I'll probably post the free range meat vlog But then I think um, I think this Surgery video is probably going to be posted next week What I really like is before you put these implants in My cheek went from like here to here. It went from like here to here now because I'm here to here So it looks a little better.  We're gonna do a giveaway for blind people And then we'll post this vlog so If you guys didn't see that Check those out before all right guys. It is friday last day in la Uh, some other person wanted this sweet. So they just moved me to this room. I don't really care I just want to like the The sole bathroom space initially because I thought I might have some stomach issues eating the food out here But my stomach's been the best it's been in the long time actually Because thankfully, you know, they're cooking all the food for me. And I just took a Another bath got all new fresh clothes on ready for the flight tomorrow morning Shouldn't be too bad. I think we're gonna get a top aware of Upstake bread and Beans for the flight tomorrow just to eat to make sure Eyes look pretty good considering. I'm not supposed to look normal for a month. Like I don't look that bad. I just look like a little weird like I'm squinting or blue steel It's just They're still dirty and there's dry blood My eyelashes are like really messed up because I can't clean them or wet them, but Yeah, we got a game plan few videos To film for next week get a few business things done but I think uh I guess like a week or two. It should slow down a little more so I'll do uh Probably Probably bored at the airport for the last part of the vlog I've been feeling really good. Even though I'm not sleeping that well But again, I probably said it a lot like I wasn't sleeping before I got here. We have copper issues. So Um I think everything looks pretty symmetrical Like the bottom eyelids are kind of in the same spot Maybe this one looks a little higher, but I can't really tell about like it's complete nonsense that I'm even looking at that until like Like a month a month or two from now. I should see how it looks and before I worry about anything Yeah, I guess we'll give you guys the outro when we're At the airport tomorrow. I'm just trying to think if there's anything else to cover today. Yeah after you took those stitches out Virtually all the pain's gone. Maybe a little tightness and discomfort. There's there's still some stitches on the end here that are supposed to dissolve but um Yeah, so over the next few months, uh, the eyes should open up a little bit more so long should go down, but So I'm swelling in the cheeks too. So It should look a little better.  I like tighten this up Sometimes I put a mask on my face too just to reduce the emf Like when I go to the airport tomorrow morning, I'll put the mask on my face To to just block as much emf as possible And then we'll put the head covers on on the uh on the flight So make sure we don't get a headache or feel bad. All right guys, it's saturday morning About to leave for the airport lax in about 40 minutes Let me really get to do anything in LA I'm gonna hang out a little bit with some kid that I argue with on the On the tiktok live streams. I was trying to get him to to do a joke Where we pretend he beat me up, but he didn't want to do it I was like the only reason I hit a lot.  Um, I think the right eyelid is slightly higher, but That I was more swollen and it does feel a little tighter by the stitch So we'll see we'll see how symmetrical it is in a few weeks, but it's still it still looks really good So I don't know I guess I'll find out in uh two or three months if this was A good idea or a neutral idea because I don't I don't think like there's really any chance of me looking worse than before I just there is a possibility that that might not look like As much better as I thought I would but I don't know you guys will Be able to tell me that so I guess this will be the last day of this vlog and then you guys can kind of just watch my progress over the Over the next few months because like I can't I think I said it in the last clip I can't wait like I can't wait like another week or two.  So Like tomorrow sunday We're just going to post the shorts with the vegan girl beating me up joke Monday we'll post The giveaway video for blind people and then Tuesday we'll be back to the meat vlog and this video will probably post it for you guys on thursday of this week So I guess that's really it Maybe we'll do some restaurant vlogs for me. Maybe I'll drive to this new york for new year and christmas or christmas in new york or something And I'll go to restaurants on those days. I don't know I don't really feel out to doing that type of stuff, but we'll see how it goes Yeah, pretty much no pain I'll give you guys a final up that I guess on the actual actual surgery instead of rambling on about other stuff Little to no pain slight tightness and sometimes a little pain in that stitch But in general, I'm just a little like Eyes feel a little dry.  I've been able to maybe do a few things Go to a few restaurants and stuff, but I don't know. It's kind of nothing. I'm too enthusiastic about doing Yeah, so who knows maybe we'll uh They will come back to LA in a few months, but the doctor's appointment and doctor check-in is it can be virtual So I don't necessarily have to fly out here. I really don't like the traveling in the airport stuff like It's just a long day of travel, you know two three hours to the airport Six seven hours in the airport on the flight and then it's a long 10 12-hour trip. So That's what even like if I want to go on vacation somewhere. I just Wouldn't be that happy to look because of the travel park, but I think that's everything I'm talking about We're in the hole for way too much money, but That line of credit I took out should cover all the surgery all the the lodging and then The giveaway as well and then I'll pay it off over the next year But I'll see you guys We'll just probably post as normal And maybe we'll do a surgery update in the three months In three months or whatever Last clip of the vlog I promise guys I'm laughing because my car is still here in the airport parking I thought maybe there's a chance that like The the new york city ticket agencies would check And like tow your car if you had outstanding tickets because after I left new york like I never paid Like a thousand dollars worth of parking tickets With my car's here, so We're not taking the cab from the airport to the tow pound tonight. Thankfully Get new york air is about twice as easy to breathe as the la


Hello and welcome back. In this lecture, we are going to continue our study of object oriented programming and specifically, we will look at the use of member functions in object oriented programming. Here is a quick recap of some of the topics that we have already studied. We have looked at a brief introduction to object oriented programming, where we basically considered the program as a collection of interacting objects. We have also seen that in C++, we can use structures to represent objects, whereas structure is basically a group of related variables arrays or even other structures. We have seen how to access members of structures, how to deal with pointers to structures and also how to dynamically allocate and deallocate structures. In this lecture, we are going to study another aspect of structures called member functions and we will see that these are really going to serve as interfaces of objects in object oriented programming. And of course, we will look at how to access member functions. Some examples in this lecture are from the book, An Introduction to Programming through C++ by Aviram G. Ranade published by McGraw Hill Education in 2014. All such examples will be indicated in slides with the citation AGR book. Recall from a few lectures back where we had seen a very quick overview of object oriented programming. We had basically seen there that when you are trying to write a program for a complex system, it is perhaps best to first identify entities which could be physical or conceptual that are involved in the working of the system. And these entities are also going to be called objects. And then we could think of the overall functionality of the system in terms of operations on these objects and interactions between these objects. And we had also seen that it is a good idea to actually not expose all the details but to hide away details that are not necessary for a particular operation. In addition, we had seen that when you are trying to design a complex system, it is best to implement the system modularily by focusing on the various entities involved in the working of the system, their interfaces and their interactions. Recall that we had also said that each entity or object is basically going to contain information specific to that object. And this information could be fixed information which usually does not change as the objects interact or it could be state information that changes as the objects interact. In any case, an object must have unambiguous well-defined boundaries. It must be very clear what part of what information is part of the information stored within an object and what is not part of the information stored within an object. Recall that we had also mentioned that ideally every interaction between two objects should happen through well-defined interfaces. And this is going to be the focus of the current lecture. Specifically, we will see how to define interfaces of objects so that these interfaces will allow us to interact with those objects. Now, the specific example that we are going to consider in this lecture is about vectors in three dimensions and this is from AGR book. So, in this example, we want to write a program to reason about motion in three-dimensional space. And so, we must deal with different kinds of three-dimensional vectors. For example, vectors representing position, velocity, acceleration and so on and so forth. So, three-dimensional vectors are going to be basic entities or objects in our program. So, we need to define a C plus plus structure to represent such a vector. And while there are several ways to represent three-dimensional vectors for simplicity, we will simply use Cartesian coordinates to represent a three-dimensional vector. So, here is how a structure for representing a three-dimensional vector also called V3 might look like. So, it will have three members named x, y, z. Obviously, they will store the values of the x, y and z coordinates of the vector and each of these three members are of type double. Now, what functions might we need to operate on objects of type V3? We might need to add two such vectors. We might need to scale such a vector by a scalar constant or we might even need to compute the Euclidean length of a vector. And there could be several more other functions we might want to use. But for the time being, let us just concentrate on these three functions. So, here is how a function that computes the vector sum of two vectors a and b might look like. Note that the two vectors are passed through reference and they are not going to be changed by the function. So, they are also passed using the keyword const. And here is a simple way of adding the x, y and z coordinates of the two input parameter vectors. And the result is stored in this vector V of type V3 which is finally returned. Similarly, if we want to scale, we are going to take a vector which is once again passed by reference here. And this vector is not going to be changed. So, we use the const keyword and we also take the scaling factor which is a double and it is also not going to be changed. So, it is used with the const keyword and then we simply scale each of the x, y and z coordinates of the vector a by the scaling factor and return the resulting vector. The function length once again takes a vector a by reference and it is not going to be changed. So, it is const and it simply calculates the square of the x coordinate, added to the square of the y coordinate, added to the square of the z coordinate and computes its square root. Now, we are going to assume that the square root function is available from a library. For example, CMath and if you include that library, you can access the function square root. Now, let us take a closer look at these three functions, some scale and length. What you notice is that each of these functions can be thought of as doing some computation on an object a of type v 3. So, if these three functions are basically doing some computation on the object a and returning some result, the natural question that comes to mind is why not associate these functions with the object a itself. So, for example, if I wanted to add a three dimensional vector b to the three dimensional vector a, I could invoke the function sum associated with the object a and pass the three dimensional vector b as a parameter to it. Similarly, if I wanted to scale up the three dimensional vector a, I could call the function scale associated with the object a and simply pass the scaling factor as a parameter. Similarly, if I were to find out the length of the three dimensional vector a, I could simply call the function length associated with the three dimensional vector a. So, what all of this is saying is that if we could associate functions with the object a, then these functions could actually serve as interfaces for interaction with the object a. If I want to do something with an object a, I could call the appropriate function associated with the object a, such that the body of that function actually does whatever operation I wanted to do on that function. Now, in C plus plus, there is actually a way to do this. Specifically, C plus plus allows you to have member functions just like member data values in structures. So, for example, here is a new version of the structure v3 that we had seen earlier. Of course, we have the three member data elements x, y and z, all of them being of type double and I could also have a member function. Here, the name of this function is length and all it does is it returns the square root of x squared plus y squared plus z squared. Now, which x is this referring to? Note that this is a member function of this structure. So, when it is referring to x here, it is actually referring to the member data of the same structure. So, as you can see here that this function can directly access the data members of this structure, compute the length of the vector and then simply return the length of the vector as a double quantity. Similarly, this is another member function which computes the sum of the current vector, the object of which this is a member function. It basically computes the sum of that object with another object of type v3 which is passed as a parameter to this function. So, therefore, what you see is within this body of the function when we say x plus b dot x, I am actually referring to the member x of the current object of which this is a member function and I am adding to it the member x of the parameter b and similarly for y and z. And similarly, this is a third member function which scales the members x, y and z of the object of which this is a member function by the parameter factor which is a parameter to this member function. So, if you take a closer look at this member function, let us say the sum member function. As I just said, you will note that this member function is actually accessing the member x of the parent object of which this is a member function and it is also accessing members of other objects passed to it as parameter. Now, how are we going to access member functions of structures in a program? Recall how we accessed member data values of structures. We used either the dot operator. For example, p is a variable of type v3 and we could say p dot x or if we are using pointers, for example, pointer p contains the address of p, we could say pointer p arrow x. Member functions can also be accessed in exactly the same way. So, for example, in this little program fragment, I have p and q as variables of type v3 and pointer q as a variable of type pointed to v3. So, I read in the values of p dot x, p dot y, p dot z. Note that I am accessing the members x, y, z of the variable p through the dot operator here and then I say q is assigned p dot scale point 5. Now, here I am actually accessing a member function and I am accessing it through the dot operator just like I had accessed a member data value through the dot operator. The parent object on which I am applying the dot operator is also called the receiver object. This is of course, the member function of the receiver object and this is the parameter of the member function. So, if you go back and look at the definition of the structure v3, within that you will find the definition of the member function scale and what you will realize is that when this function is called, basically this code is going to be executed. So, a variable of type v3 is going to be allocated and its member named x will be set to the value obtained by multiplying point 5, which is the value of the parameter factor with the value of x of the receiver object. So, basically what this will do is, it will take the value of x of the receiver object p. So, it will basically take p dot x, multiply it with factor in this particular case point 5 and it will set p dot x times point 5 to v dot x. Similarly, it will set p dot y times point 5 to v dot y and p dot z times point 5 to v dot z. This z that we are referring to here is the member z of the receiver object, which is p in this case and of course, if I am trying to access a member function through a pointer, then just like when we are trying to access member data values through pointers, we have to use the arrow operator. So, here pointer q is a pointer to the receiver object and this is a member function of the receiver object and so I can use the arrow operator to say access the member function length of the object pointed to by pointer q. So, in summary in this lecture, we saw how member functions can be used as interfaces of structures and we also saw how to access member functions of structures in a program. Thank you.


I welcome you to this session. In this session, we will discuss the Unit 5 Accounting Process 2 of Financial Accounting of Become First Semester. In this session, we will discuss the first part that is the journal and how the transactions are entered in journal. The whole discussion will be divided into three parts, the first part that I have already mentioned, it will be on journal and how to record the business transactions in journal book. The second session, we will discuss about the subsidiary books and the third part of the discussion will focus on the preparation of leisure. So, learners, let us begin with the first part that is the journal. So, journal is a book of account. Book of accounts means the book where accounts are there, means the book contains the accounts.  So, all the transactions will not be recorded, only the concerned transaction relating to a particular account will be recorded in the particular place that is known as account. So, the book that contains the accounts, for example, the book may contain the accounts of all the creditors, the accounts of all the debtors. So, these are the books of accounts. All the purchased transactions will be recorded in a particular account that is purchase account. So, purchase account will be in the book of account. So, the books of accounts means the book which contains the different accounts. In the accounts, we know that the business transactions are recorded. Any transactions that takes place in the business will be recorded in the accounts. These transactions are recorded in a very systematic way. First we will record it in a particular book that is journal, then we will post it to the ledger and then we will prepare the trial balance as well as the final accounts. So, all these transactions will be recorded on the basis of double entry system. Double entry system that we have already discussed in unit 4, it is the system where debit and credit amounts are equal. So, we will discuss it further. Let us move. Now, types of books of accounts. So, books of accounts that contains the accounts and these books of accounts can be classified as primary book and secondary book. So, primary book will contain the journal book means the primary book is the journal book. It is also known as book of original entry. Means, any transaction that takes place in the business that affect the business will first be recorded in the journal book. That is why it is called as the original entry. The first book of account where a business transactions as it takes place will be recorded in journal. The secondary book. Secondary book is the ledger book. This is also known as book of final entry. Means, all the transactions recorded in the journal will be posted to ledger. From ledger, we will move towards the preparation of final accounts. So, journal is very important as any transaction that affect the business will be recorded. So, in journal, how the transactions will be recorded? The first of all, transactions are recorded on the basis of dates. So, a chronological order is followed when transactions are recorded in the primary book. Then, transactions are recorded on the basis of certain documents. These are known as source documents. These are proof that a particular business transaction has taken place and the accountant is authorized to record that particular transaction in the journal. So, these source documents may be cash receipts, may be vouchers, may be bills, invoices, etc. So, this is the documentary evidence of a transaction that a transaction has taken place in the business and this is the evidence. On that basis, the accountant will record that particular transaction in the journal book on the date on which the transaction takes place. Then, transactions are recorded as debit and credit. So, debit will be recorded or a part of the transaction will be recorded on the debit side of the account and the other part that is credit part will be recorded on the other side of the account. Let us take two examples. A very simple example that two transactions take place. Number one transaction furniture purchased for Rs. 10,000 on October 2020 and the second transaction which purchased for Rs. 5000 that took place on 22nd October 2020. So, this is the format of the journal and on the date column, we will record the date where the transaction takes place. Then, in particular column, we will record the details of the transactions, the debit. As you can see, furniture account has been debited and cash account has been credited and again we will see the column LF that is ledger folio. We will discuss this later on. Then, there is two columns are there, debit column amount, 10,000 and credit column amount, 10,000 we have written against the first transaction. Again, in the second transaction, we have recorded the date, the date when the transaction takes place. Then, we have debited purchase account and next we have credited the cash account. Then, the same amount has been written on the debit column amount that is 5000 as well as on the credit amount column, the same amount 5000. So, this transaction has been recorded by following the double entry system of bookkeeping where debit equals to credit. So, same amount has been recorded in both the amount column of debit and credit. Then again, we can notice within brackets in both transactions, we have recorded a particular line that is being furniture purchased and in second case, being goods purchased. So, this is known as narration. This is a brief explanation of the transaction. What has been recorded? It is written as being that is traditionally added and just is written to know the meaning of that particular transaction. Steps in recording the transactions in journal book. So, this is important because we have to follow these particular steps to record any transaction in the journal book. The first step is identification of accounts involved in a particular transaction. Any transactions that you have to record it in journal, first you have to identify the accounts. Then, in the second step, we have to classify the accounts and in the third step, the application of the rules of debit and credit according to the double entry system of bookkeeping. So, we will discuss these steps with an example. So, let us record the transaction goods sold for rupees 3000. So, in this transaction, what has happened that we have sold goods means our business has sold goods for an amount of rupees 3000. In the first step, we will identify the accounts that are involved in this particular transactions. In this transaction, the accounts involved are sales account means we have sell some goods. Goods mean that our business regularly deals in and the amount of the sales is rupees 3000. So, sales account number one and number two cash account. These two accounts are involved in this particular transaction. So, in the first step, we identified the accounts that are involved in this particular transaction. In the second step of recording transactions in journal is classification of the accounts means we will classify the accounts. You are aware that according to traditional approach, we can classify the accounts as personal account, real account and nominal account. So, sales account is nominal account that relates to expenses and losses and incomes and gains. Then cash account as cash account is involved in this particular transaction, cash account is real account that signifies the property of the business. So, cash is property. So, it is a real account. So, in the second step, we classify the accounts. What are the accounts? And in the second step, we classify the type of account. In the third step, we will follow the rules of debit and credit. And according to the rule, in relation to nominal account, debit, all expenses and losses and credit incomes and gains means any expenses, any losses relates to the nominal account and it will be debited. And incomes and gains related to the nominal account. So, it will be credited. So, in this particular transaction, this will be the journal entry. So, debt we have in a debt column we have recorded the debt 2210 2020. In the particulars column, we recorded cash in the debit side. Whenever we sell goods for cash, cash comes into the business. So, if we apply the rule of real account, cash is a real account. So, according to the rule, debit what comes in and credit what goes out. So, cash comes into the business whenever a sale takes place for cash. So, cash account has been debited. It is written as cash account and against that we have written the short form of debit that is DR. And sales account, it is a nominal account, it gives revenue, it gives income to the business. So, we have applied the rule of nominal account means incomes and gains are recorded on the credit side according to the rule. So, we have credited this sales account for this particular transaction. So, cash account debit to sales account and what we have done in this particular transaction, goods have been sold. So, being goods sold, we have recorded it in the form of narration. Both the columns of debit and credit will be recorded as 3000 and 3000 according to the double entry system which says that debit must be equal to credit. So, this is all about the first part where we have discussed what is journal. Journal is a primary book where transactions are recorded chronologically. And we have also seen how to record the transactions in journal book. There are three steps and we have followed all the steps and how to record the transactions by identifying the accounts, by classifying the accounts and by applying the rules of debit and credit. Thank you.


One important concept that we want to discuss is that of divisibility, and so we have the following definition. Suppose I have P, M, and K, all integers, and suppose I know that P is equal to K times M. Then, I say one of several things. First of all, I say that M divides P. We also might say that M is a divisor of P, or we might say that P is divisible by M. Now, the last is actually the most common way we have of stating this particular property. We say 25 is divisible by 5, 100 is divisible by 4, and so on. However, for purposes of how we write this mathematically, this is actually the worst way to state this, because the mathematical notation we use is the following. If M divides P, we write M, and there's a vertical bar there, and then P. Now, there's some important properties about divisibility. These are basic properties. They should be fairly obvious, and you should be able to prove them by referring back to the definition of divisibility. So, for example, if M divides P and M divides Q, then M divides P plus or minus Q. Likewise, if M divides P, then M divides N times P for all integers N, and what's almost as important are identifying things that seem like they should be true, but in fact are not always true. They are sometimes false, and so they are not reliable. So, here's probably the most important one. Suppose I have M divides P, and then I have something else N also divides P. Then we'd like to think that the product MN will then divide P, but that's not true. So, here I have 6 divides 12, 4 also divides 12, but 6 times 4 is 24 is not a divisor of 12. Another property we think should be true, but is not always true, is that if M does not divide P and M does not divide Q, then M shouldn't divide the sum or difference of the two, and that's actually the inverse of this property, which actually is true, that if M divides something and M divides something else, M will divide the sum or difference. Now, if M doesn't divide, is it possible that it doesn't divide the sum or difference? Well, again, this is false. This is not something we can rely on. 5 does not divide 8. 5 does not divide 12, but if I look at 8 plus 12, that's 25 does in fact divide 20. And again, we have something that's similar to the inverse of this second property here. If M divides P, then M divides any multiple. Well, if M does not divide P, and likewise does not divide Q, we might suspect that M does not divide the product P times Q. And again, this is false. This is not true. We cannot reliably claim this. And as a good example of that, 8 does not divide 12, 8 does not divide 2, but if I take a look at 12 times 2, that's 24, 8 does in fact divide 24. So let's do a quick proof, prove or disprove. This number 5 to the 3rd, 7 to the 5th divides 140 raised to the 10th power. Now, one possibility is we could figure out what 140 divided to the 10th power is, and then see if 5 to the 3rd, 7 to the 5th actually divides it. But we should go back to our definition of divisibility. So to determine whether 5 to the 3rd, 7 to the 5th divides 140 to the 10th, what we'd like to do is we'd like to see if 140 to the 10th can be written as a product of 5 to the 3rd, 7 to the 5th, and something else. Now, the fundamental theorem of arithmetic says that we can express every number uniquely as a product of primes. And so what we should do is we should try and write both of these numbers in terms of a prime product. Now, 5 and 7 are primes, so this is the unique expression of whatever this number is in terms of its prime factors. 140 is not prime, so I can write that as a product of primes. And so that's going to give me that. Raise to the 10th power is that raised to the 10th power. And I can apply my standard rules of exponents. And what I'd like to do is I'd like to see if I can write this as 5 to the 3rd, 7 to the 5th times whatever's left over. And I can do that. I have a bunch of 5s here. I have a bunch of 7s here. And hopefully I will have enough, so I'll rearrange my factors a little bit. And there's my 140 raised to the 10th, 5 to the 3rd, 7 to the 5th times some other stuff. And so I know that 5 to the 3rd, 7 to the 5th does in fact divide 140 raised to the 10th power. How about a different problem? 112 divides 36 to the 15th, yes or no. And again, I want to write all of my numbers as products of primes. 112, 2 to the 4th times 7, 36 to the 15th works out to be 2 to the 30th times 3 to the 30th. And remember that one number divides another only when I can write the second number as a product of the potential divisor and something else. So I'd like to write this, 36 to the 15th, as a product of 2 to the 4th times 7, and whatever's left over. However, there's a problem. 112 requires a 7. I didn't have a 7 in here, so there's no way that I can write this as a product of this and something else. So because of the prime factorizations, because I need a 7 to make 112 and I don't have it, then 112 does not in fact divide 36 raised to the power of 15.


In one of my Fusion 360 online weekly classes one of my students brought up this model from the very talented Sven with ClockSpring3D. It's basically a box but instead of using friction fit or a snap fit mechanism it uses a horizontal thread to lock the box. I was asked to do a tutorial on how I would go about designing this model. Now Sven does have a video showing his approach and I'll link his video below along with a link to his my mini factory site with all his designs. I definitely recommend checking out his work. In this video I'll go through a brief walkthrough of my timeline and show how I approached this design. If you want the full step by step tutorial where you can follow me as we design this then check out my Patreon page where I include the full design tutorial to this and my other projects along with the Fusion 360 file for download. Here's the Fusion 360 model and as you can see this is modeled in three separate parts. We've got our bottom section here and then our top and the top simply slides right on to the bottom so if you see here if I just take this move it up and slides right down and I've got a 0.3 millimeter clearance there which I'll show you in a second and then I've got a threaded nut here on the front. So the approach I took here is a little bit different than Sven's model because he does the threaded nut on both sides. I found that that wasn't really necessary this was good enough to hold the box in place and so instead of doing another thread on the back here I simply mirrored this portion here of this little bump out so that you can actually just be able to grab it and pull the box down. So that was the approach I decided to take now of course if you're someone who loves symmetry and that's important to you then yeah go ahead and recreate the thread on the other side as well. Okay I'll go through my timeline here I'm just going to drag it all the way back to the beginning and just do a quick walkthrough through my design approach that I took here. So the first thing I did was create a sketch and you can see here this is a center rectangle that I created right on the origin and the important thing here to know is that I did an offset of 0.3 millimeters and that becomes my clearance for the fit. I simply created two rectangles well one rectangle and then an offset and then I extruded that rectangle and then applied a fillet and then came in with the shell. Now the important thing here is I did an inside shell of 2 millimeters and I'll show you in a second why because this is sort of a different approach to just creating these fit boxes. So and then I created let's see I've got a sketch here which I used to create that bump out and there it goes and then I mirrored it to the other side. So that's that and then I created the top body and then for this body what I did is going back to that sketch I basically now I extruded both profiles. So the first profile or the first extrusion for the bottom was just to extrude the inside profile to create the top I extruded both profiles including that little clearance section and then I filleted and then shell so the same thing. The difference here is with the shell I did an outside shell so it's adding material to the outside of the body and then that way you know that ends up leaving me with that clearance fit already sort of in place right there that point 3 millimeters. That was the basic approach draw the rectangle extrude both sides the one as an inside and one as an outside shell and that worked out. Let's see and then the next thing I did here I just brought use the line tool to bring the top part down here I mean I got this flipped and then I did a boolean operation here next so this is going to be a just a combined cut here to cut out the section here that little bump out to leave me with the top portion with the cutouts right there and then the next part is really important because that's the offset here to give me the clearance so I did a here an offset face and that just basically let me see if I bring this back if you take a look you'll see that these will bump out just a little bit and that's that point 3 millimeter clearance that I included in there so that this would actually fit. All right and then another sketch here let's take a look at what that is so this is the circle I made to create the threads the approach I did there was just extruded the cylinder applied a thread and here you want to make sure that you have model checked and I went with the courses threat designation it gave me which is this M18 by 2.5 and then this technique here this actually Sven uses the same technique and I thought it was actually pretty helpful in creating this thread here to print horizontally and basically you scale let me remove the top portion here. So just basically involved you take this thread and you scale it but you do a non-uniform scale and you're basically scaling it out this way which kind of stretches the thread making them coarser allowing them to better print and actually work in this orientation so thought that was a neat technique there all right and then I simply aligned that into place here and let's see it in so the next part I wanted to do here was create a chamfer right because of this overhang here and we don't want to have to deal with supports when we're working with threads so what I did was create a sketch and apply a chamfer there through the sketch and the way that worked as you can see I created this triangle here and when I did the extrusion there I just took that triangle and extruded it all the way through but instead of doing a cut I did an intersect and that way it just kept the part of the profile that overlapped that the thread there so that left me with exactly what I wanted which is this shape here now I applied that same principle to the top so if I move this you can see I drew another triangle here on the top and then extruded that through using an intersect and the way that worked that basically just left me with this chamfered edge here that makes it a lot easier to be able to thread this so that's the approach I took there and then my next part here is I use the split body to split the thread in half so let's let me show that I just use this surface here to split this the thread in half and I have this here with two bodies and then I went ahead and combined them to each section of the top and the bottom part of the box to do the the actual not the approach I did there is I extruded that same circle went ahead and shelled it and did an outside shell and then apply threads to the inside so same thread profile then I went ahead and scale that again same idea non-uniform one direction and then let's see oh and then I did the circle here and then applied a circular pattern I actually extruded this first and then once I got that one cut out there I filleted it and then applied a circular pattern to give me the rest of that pattern there and then it all came together to create this really neat design there's something so satisfying about this box I got to tell you just sliding it together and locking it in place so that was my approach I took here in designing it if you want the full step-by-step tutorial and want to follow along with me as I create this model check out my patreon page where I will have that as well as the Fusion 360 model here that you can download and play with the design alright guys that's my approach to creating this design I did this for my weekly online class as a request of one of the students if you're interested in joining that class I'll leave a link below where you can find out more information and if you're just looking to get started with Fusion 360 check out my quick start guide I've got a link below to that as well all right I'll be back in a few with a new project
