We've look we had a very rare night out on Saturday night We thought it was like Friday. We're like, you know what?    It's going out. It's getting over it though. Hey, it's like we just sit at a table and Hand us a bottle and then we just Sort of try and speak loudly to each other. Yeah, I don't remember. I wish I remembered it It's all just like it didn't happen.  I run a mark mate. We run.  Where were you mate?  Oh, yeah. Oh, yeah, or like even just like What's the other one that people have depression depression?   Just no no way. We're as bad I don't know maybe because I didn't all my co-experiences have been I've had good spaces like yeah couple of months between Yeah, that's fine. Yeah, but you know it's been a while since we've done it, but it's still just never as good as it was when you begin So true but yeah, so that was our weekend.

Okay, but if you could just maybe leave a comment leave the comment comment You like the video and subscribe. That's helping off man. That's all we need last week's podcast is performing very well Matthew, we're back up to the bloody bigger numbers now more views. That was nice. Hey, I think we have a strong start Yeah, very good.  Well, I just like the video don't whatever I'm sick of asking I'm turn it.  I just listen to it.  Just listen on up. Yeah, don't even listen to this.  You still have to be careful All right, they're not it's not a hundred percent foolproof You can't just be super reckless.  They're just go across smoothly fine.  Oh, maybe I don't know Oh, yeah, you gotta you gotta be regularly. But yeah, this thing I swear to God.  We didn't even realize this was a thing the podcast award. So this year Where aware that they've opened the nominations now, so we have to nominate ourselves So you guys don't need to do anything yet, but we're gonna I'm pretty sure it's pointless Because they want us to send in what is a mat three minute clips from a podcast Yeah, it's something along those lines So we're thinking like what do we send a compilation of me ripping my arse cheeks apart? Do we send a Matt Brown diary entry? No Obviously we can't send that to these mainstream Award ceremonies, so we'll see if we can come up with something But if we can't even if we are not nominated for anything The listeners choice will be the lot.     All right, because it's pretty cool the Australian Academy of Cinema and Television Arts Awards known as the actor Awards So it's nothing like that's a very big award show that we're not nominated or anything yet So what they do is they con they've contacted like 20 like Can what do you call it like people who make comedy videos online? They've contacted 20 different creators in Australia and where one of them So now I had to fill out our application So now they're gonna get industry professionals to vote and out of the 20 They're gonna pick five of the better.  Yeah Killed it Anyway, so that's what we've submitted. So now we find out soon Industry again industry professionals have to vote for this or so.  Yeah, I know your humans actually like animal series is probably some of your most PG work, but it's very exact I don't see why you you should count yourselves out. I think you should be sure you can cast Yeah, but like the even the entry forms.   I hate to say that Yeah, we might just be like a shown a snippet of the footage or something my sister not many drop names.     Yeah, let's see who's calling right now.  I've a very good secret. We got some questions from you guys We got um, well, there weren't many comments for the hunt in the last one without I saw like three or four Probably not enough to we'll see how we go with time. All right There was another segment A lot of people are asking about German segment. We've got an idea here guys. Okay, so We want I don't remember it. Well, I did get one guy Everyday live that's all you do now is just my idea is and then forget I did have one guy comment I'm sorry.  And yeah, if you if there's just comment jokes, whatever you anything funny goes and the definitions We want yeah, we had an idea. I don't know. It's pretty high. I came up with it like our definition of things So you send us like a word that you want to know what the actual definition is because the dictionary is just like It's just some random dudes opinion, you know Well, someone did ask a question of what I'll get to it. But yeah, they asked what a certain word means Yeah, so if you want like the scientific actual real description and what words are and stuff like we know We've been doing this shit for years Why not share that skill one like if so if you have a hard word or a phrase or something just anything in life You don't understand We can explain the science behind that.  What are we gonna call this Marty Michael explains it? We'll just call it Explaining things finding things. Okay. All right. It's gonna be a new segment next week.  I've figured out what I want for my funeral I want the song mama Mia by Abba played as my corpse is lowered into my coffin by a rope That's tied around my lower jaw and all attendees have to throw darts at my body Then I want to be shot out on a rocket which is headed for the Southern Cross star formation And that is where I want my body to rest again. This is legally binding.  Do you like Abba? I reckon Abba's good. Abba's like oh, they've got some all right Exactly your mum from the 70s also show me the Beatles. Yeah, but everyone liked the Beatles Everyone liked Abba only only disco disco everyone like the Beatles 50% like that man. They were good Abba is like Abba is like the Five seconds of summer version of the Rolling Stones. Oh wow, that's pretty good description. Yeah, that you can't I hope they were heavy into cocaine. Anyway, yeah, I think next time diary entry number 105 from Marty Today I played with my pet flies. I found them in my room. I saw them flying over a plate of old mince I found in the neighbor's bin.

I was getting close, but I was fatiguing I needed help and fast.  Oh, that's horrible. Yeah, you remember it Imagine getting castrated. What's that?   Can you say that Matt?   That was that was pleasant. Well, um Yeah, wow, so your therapist wanted you to get castrated That must have been like man, do they do that in real life?   Yeah, are you lying? No, okay Fuck, I didn't know that that was we should do that for a video through does chemical castration work Is it a forever thing? I think so. Yeah. Yeah Yeah, maybe it's a strong maybe all right.

There's a lot of people Get addicted to the the attention they get from When they go there from they don't get that attention in normal life So when they go over there and they get all this attention Well, I think like old dudes in general go over there just because that the amount of prostitutes there are It's like they're in heaven exactly and patio funny little story here I've said this before probably but that's where I first found out what prostitutes were when I was like eight years old We're in patio, which is like one of the sex capitals of Thailand.

Last year, in this conf, we launched something called as Ruby India. How many of you heard of Ruby India? Quite many. Ruby India was to highlight content from the Ruby Indian community, like send out links for submitting CFPs. What is happening in meetups? Different meetups and all those things. Do subscribe on Ruby India. Our next issue comes today again. Along with Ruby India in the last Deccan RubyConf we announced podcast.rubyindia.org. So do visit again podcasts where we interview a lot of people in the Indian community. Recently we interviewed C42. Anyone? So do check out the podcast. We interviewed Gotham and many other people from the Indian community. And we like to interview them and ask different things about how the Indian Ruby community, how it came into being. Also, this is not a magenta. So that's all about what we are going to present. Before I begin, I'll just let you know. So Prathamesh, I've been working on pretty funky things these days. This is one of the start-ups that I started called as Backpackers. So I've been travelling a lot recently and I've travelled and I like to stay at different places since my job is remote. So I also made a lot of friends who backpack. That's why Backpackers. It's an actual company which is registered. So these are some of the things that my start-up does. I like to help out my friends in basic task management. Finding good locations for when they are roaming around in different locations. Finding good places to visit. Finding good food centres because I don't know. We want food. We don't know what to eat. And finding good and cheap hostels or hotels around. But all of these tasks are very basic tasks. Every app has it. What is your unique feature? We also have many magical features. Luggage is always lost. So we also have this very magical feature called a Spind Your Lost Bag. So anyone who has heard of RKH Lost Bag, sorry, RKH Bag, only one person who has the tutor handle. So we also have these magical features which allow us to have these many happy customers who find their bags when they are lost for two weeks or I don't know. And our customers are mind blown with our features that are there. So before I go into the other features, I'll give you an idea of what I like to use, a lot of active record and all those things. So this is something that I have in my app. I have a traveler class which takes care of reviews and bookings. I have a task which belongs to a location like what I want to do for that particular location. I have a location which will keep information about the location and it will have reviews. It will have different bookings like for hostels. And it can have nearby locations, which is a self-join on that particular model. I also have bookings which are related to locations. Very sophisticated code. And you can't believe it but I actually have this app right now and it's in production. It's actually running. So do visit my website which is backpackers.herokuapp. So just fire up, I don't know if the instance is running or not because it's production. And I actually have live 31 users. Looks like your app is scaling. Yeah, which is like, I don't know if you have ever seen 31 users in your apps because it's production. So, I'm sorry. Yeah, I mean, yeah. I mean, 10, okay, I understand 10, but I mean, 10 are like from your company, but 31 is like a lot. And I'm a single person company, you know? Nice. And since I have 31 users on a single Heroku instance, I like to have performance like performance is very important when you have 31 users. So I like to scale my app a lot. That's why I use raw SQL, you know? Because active record is very slow for me. It's, I don't know.  So, you see, if I have this query over here which does searching for food, like searching for a QZ, if I'm going in some other country and I want to find Indian food, which is very hard. I don't know if they don't even know what is Indian food. So I like to have these raw SQL queries that I have in my app, which help me find that. So you can find, see, I'm using I like over here since I'm using Postgres. So you can find your Indian food or related cuisine. So this kind of works well. Yeah, this kind of works well. But you know what? It does work. And it scales. Yeah, I know. But it has some problems. So have you thought about the problems? What problems? So it has raw SQL. That is the first thing. Then it has some... It has performance, I don't know. Yeah, but it has some database-specific things also. Like I like. And if you want to move to some other database, I don't know whether you will move from Postgres to other database. But if you want to, then it will cause problems because that query will not be reusable. So in that case, Errol will help you. Have you heard of Errol? No, what? What is Errol? Errol is a Ruby library. It is used for generating SQL. So it is actually based on relational algebra. It has concepts like abstract syntax tree, nodes, visitors. And it stores that query information in all those AST and nodes. And then it just generates the SQL. So it is used by ActiveRecord under the hood for generating those chain ware clauses. It is used from Rails 3 onwards. But it has also lots of other features which can help in use cases like yours. And those are not exposed through ActiveRecord API. And also it is largely undocumented. So I know that you might not be knowing about it fully. I don't know what Errol is. Yeah, but I will help you. I will help you how to change the... We already have ActiveRecord. So why is there Errol or why do I need to care about Errol? Well, ActiveRecord is full-blown ORM. It does a lot of things. It runs your queries. It converts your SQL result into Ruby objects. It converts them back into SQL. But Job of Errol is just to generate SQL. Nothing else. So... True. Yeah, it doesn't even know about your database. It doesn't even know about what your table structure is, what your columns are. It doesn't know anything. Just generate the SQL. So ActiveRecord will actually connect to your database. It will get the columns information. It will get the table information. Give it to Errol. Errol will generate the query. And then it will give it back to ActiveRecord. ActiveRecord will execute it. And you're done. So that's how the flow is. And how exactly does this Errol work? And how do I use it? You don't have to do anything for using Errol because once you include Rails, which includes ActiveRecord, Errol is just a runtime dependency. So once you have the Rails app running, you already have Errol. You just don't know about it. In production? Yeah, in production. So for getting started with using Errol, we just have to grab the underlying Errol table object. This is the starting point. And once we grab that, then we can build our queries based on whatever attributes that are present in that table. So we can write this convenient method. So ActiveRecord core class has this Errol table method using which we can access the underlying Errol table of that model. And we can write convenient method like this. So location.table will give us the Errol table. So let's see how we can refactor your query using Errol. So here what we are doing is we are just matching our QZen attribute.  And it will generate the same query. Nice. And it looks cleaner. Yes. So table of QZen will give you the attribute, Errol attribute. This is the basic structure for representing your column. So once you have the table, you also have attributes. And similar to QZen, you can get other attributes, like pricing, location, ID, whatever. All of your attributes are possible. And then you build a predicate on that attribute. So matches in. That attribute should match to your search terms. Got it. And this predicate will ultimately generate an abstract syntax tree. It will store all the query information for this particular clause into that AST. And then we can feed it to your bare block. So just like we can pass hash arguments, string to where, we can also pass AST. And ActiveRecord will internally handle how to pass that AST and how to generate query out of that. But yeah, you can basically pass any AST to the bare clause and it will generate the same query. This looks interesting. Yes. And once you run this query with MySQL, it will give you the light query. So you don't have to write database-specific things. Also, you can extract this predicate into a separate class method and then you can reuse it. So almost all of your problems are solved. And it becomes database agnostic. So once you write a query for one specific use case, it will run for almost all databases. So Errol supports MySQL, Postgres. It also supports Oracle, MSSQL. This looks interesting. Yes. So tell me, how you will handle this use case? Let's say the user doesn't want non-vegetarian food. Dude, whatever. I mean, this is pretty simple. I don't know why you're asking me. I just use this query called as I use not I like. I just have a lot of people who are like you, who are vegetarian. So I have this handy query which returns me all the queasy because we do not have non-vegetarian food. Yeah, but we can use Errol in this case also. So it's not just limited to generating positive predicate. For every positive predicate, it has a related negative predicate also. So just like match, you can use does not match and all kinds of things. So these are all the list of predicates that Errol supports. And one of the interesting feature of these predicates is there are star any and star all. So you can pass array arguments to these predicates and it will generate proper and or or SQL for you. So generally we have to kind of juggle around with the strings to possibly like properly handle that. But these methods are very convenient. I mean, okay. But you know, this is not, this is very, I mean, you're speaking very simple things. These are very like, you know, small things, which are easily done by, you know, a raw SQL or active record. Does Errol allow me to do hardcore things like, you know, I have this query over here, which is what is trying to do is find locations which have bookings. And it is trying to find locations which have ratings greater than three. So I'm using, you know, pretty hardcore stuff over here, which is joins. Okay. So I'm trying to find, do an inner join because active record doesn't allow, I don't know why to do an inner join on the same table. And then I'm trying to find all locations like. Yeah. You have a extra end condition. Yeah. And then I'm fine at doing a join on another table. And then I'm also doing an intersect to find all the places which match for this particular query. And this is very hardcore. I don't know.  Well, Errol really really shines with the joints actually. So Errol will can generate any kind of possible complex joint very easily. Okay. So I will show you how to do that. So the key to generate queries using Errol is to break down those into smaller parts and then reuse it at the end, like break and then compose at the end to build the final query. So let's solve the first problem. You want all reviews having rating greater than three. So we can use the GT predicate. We are done. Okay. True. Now let's do the joint. The problem with active record join and why you have to go for SQL was that you have to specify the extra end condition, which was not possible. Right. And so active record join method is a bit of magical. Like you just specify the association name. It will figure out which foreign key to match. It will generate the inner joint properly. But in Errol you have to specify each thing as you go. So first you specify on which table you want to join. Which is the review. Which is the review. Okay. And then you specify on which condition, like what is your joint condition. So if you go to next, then you can specify on which condition you want to join. So this is just a simple predicate that we already saw. Right. And in active record you are limited to equality predicate for joint condition. But here you can just replace that predicate with any other predicate also. True. Okay. Which might not be a common use case, but you can do it. It's possible. And then you can specify the extra and conditions. So you can specify the extra and condition for your joint. And that can be on the review table. It can also be on the location table. It's like you can specify any of the predicate that you want. Okay. And at the end we just want to select something from it. So as Errol is based on relational algebra, it has its roots, like it has concepts like projections, which are similar to selections in SQL. So we'll project everything. We want to project star. So we do Errol.star. Errol.star is just a convenient method for accessing star. And we are not just limited to inner joint. So generally if you want to do any kind of left join or full join or outer join, then we have to write raw SQL. But Errol supports other joints also. So the second argument to join function is full outer join or outer join. Any other? I don't know where you're going, but try to focus. I don't know if everyone else is following, but I'm following over here. So please focus what we were trying to solve. We are not trying to solve the, I don't know what you're saying, outer joins and stuff like that. Try to focus on the query. Yes. Focus. Yes. I'm focusing. So we want to get all the locations with bookings and all the locations with rating greater than three. Actually, you know what? We already solved the problem. So the first query is we get all the locations with reviews and whatever your condition. And second is we just want location with bookings. We are not doing anything magical here. So we can use the active record way of handling the inner join. True. And then combine them using intersect. You're done. Again, intersect is what? Intersect will just intersect the two subqueries. It will get one AST from here. Something from here? Yeah. Obviously, it's from there. That's what I'm saying. So it gets one AST from the left side, one AST from the right side, and it will intersect that query properly. And you're not just limited to intersect. You can do unions. You can do except clauses. So not just, and you're also not just limited to two subqueries. You can run this on any number of subqueries. It's possible. So all kinds of combinations are for that, but okay. Fine. Well, you're not still convinced with error. I mean, fine. This is like, I don't know, very simple stuff. Okay. Joins is okay. Joins is also simple. Let me give you a harder one. So I have this, you know, hardcore thing, which is called as self-joins. I'm going over here and I'm trying to find all hotels within five kilometers. Like people try to, when they try to search, like my friends try to search for hotels. They usually look places where they have malls or they have places to visit. So I have also provided this functionality. You know, I have nearby locations, which is a self-joining model. And then I do something like this. I don't know what it is. It's like inner joint on the same table. Try to find locations and location is less than, the distance between the two locations are less than, you know, five kilometers or whatever. And it's like, this is something that only my app provides in the world right now. So it's very hard. I don't know. You will be able to do something about it. Well, Erl can help you in this also. So Erl has a concept of aliasing. You can create alias for different tables using the alias method. And then you can generate the same query back. So in your case, you want nearby locations, right? True. So we just generate the alias for nearby locations. And then the joint sources method is... The alias is referring to the same table? Yes, yes. As it is using the table method, it is referring to location. Location. Okay, got it. Then we just, as usual, we specify our joint condition. And the key here is the joint sources method. So what that does is it gives you the underlying Erl's joint representation of that node. Okay. It's a bit hard to understand, but just consider that you get Erl's representation of joint. That's it. No, I don't care about that. Yeah. We don't have to care about it. We can specify the extra end condition just like we had earlier nearby locations. Yeah. The same one. The same one. And once we get that joint sources, we get an array of Erl node joints. We can feed it to active record joints method. Cool. And... So just like we can feed abstract syntax trees to ware clauses, we can also feed Erl joint nodes to active record joints method. Is this something which active record uses? Internally, it does. So as it supports string joints, as it supports association joints, it also supports handling of Erl nodes. Okay. It's nice. So it will again generate you the same query back what you had in raw SQL. Fine. I don't know. But these are all... Okay, this is also a good feature, but I don't know. These are all simple things and I also have these very complicated things called as, you know... Yeah. Making my app secure because 31 users are sharing their information with me, so I want to make it secure. So I use very complicated things you can see over here, which is... I like to use direct... Direct... Yeah. Encryption functions directly from database because Ruby is slow. I don't know why. So I use these things called as pgcm encrypt. I'm using Postgres, so I'm using those kind of things. Yeah. I'm using the setsecret, which is fetching... encrypting it from database and then setting the value for the particular field or I'm using getsecret, which is executing again and trying to fetch this by decrypting that particular value. And this is very hardcore. Don't fit Arial into this. I don't know why you would like to do that. Yes. And any library can't do it, like Arial also doesn't do it, ActiveRecord also doesn't do it. See, I told you. But wait, Arial supports this with name functions. So Arial has this concept of functions, name functions, which can be used as wrappers for our SQL functions. So we can wrap the SQL function in a Ruby object and then we can reuse it for our needs. So your pgpcm encrypt can be wrapped into this name function very easily. You just pass the name of the function, its arguments. Optionally, you can pass the alias. So once you pass the alias, it will generate the proper ads clause. This looks like... I don't know. My one was simpler than this. I don't know. This is very big. Well, in this case, it can be big, but let's say you want to order your criteria. Using some ordering criteria, like police, then you can generate a function for it, wrap it in name function, and then pass it around for your order clauses. So, I mean, you can reuse it as per your needs. It's not just limited to selections. You can pass it for other active record methods, like order also. Because... I don't know. ...Indian, it just generates the AST. So whatever accepts the AST, you can pass it. Fine. No dials. I don't know. You're still not convinced? Fine. Okay. So, in the end, we covered a lot of things today. We covered kind of complex predicates that are possible through ARL. We covered combinations using intersections. We covered unions, except... Then we covered joints. We did all kinds of possible joints that are possible. And we saw, like, how to use ARL with an active record, to enhance it, or to use it in our... To use it to build our queries in a more object-oriented way. Yeah, if you put it that way, it was... I don't know if for them, but for me it was quite useful. I'll try to... Since my app is very... Can you take me as a co-founder? No. Okay. I need to scale. I don't know. With your expertise, I'll be able to scale or not. But anyway, this was pretty interesting for me. I don't know. I'll try to take a look and maybe refactor my app. It was pretty helpful. I don't know. And also, thanks again. And this is not... Again, this is not Majin Teh either. Thank you. Our code is at GitHub. And you can sign up for Vipul services. Yeah, so... sole proprietor of Backpackers. You should check out my app and register and help us get the user account greater than 31. You can register only if you're okay.


The one thing just to quickly look at before we finish this video is this area of stereochemistry. We've got to remember that we are dealing with three dimensional collisions and this is what makes life very difficult because we're trying to model processes in two dimensions that are actually occurring in three. One of the things that's important in collisions is not just how often they occur or how much energy they have but also the orientation. So you can see here we've got a collision between a particle of hydrogen and chlorine, so hydrogen chloride and here a double bonded hydrocarbon. This one is ethene. Now in this region here we have a very high density of electrons, so a very strong electronegative region. For this molecule we have polarity. The polarity is created by the greater electronegativity of the chlorine than the hydrogen which means we get a slightly negative, slightly positive region happening here. Over here slightly positive, slightly negative. You can see for the one that we've said will provide a successful collision reaction is where this very negative region of concentrated electrons is hit by this positive region where the hydrogen is coming in. Two negative regions effectively running into each other or coming in from the side and these bonds here are non-polar and so there be no interaction between them. This additional factor can affect collisions as well. It can not just be a factor of how many particles and how much energy the particles have but also the orientation of those particles and how they approach one another as to whether the reaction occurs. So hopefully this gives you a little bit of an idea of some of the ways that we can use our understanding of particles and collisions of those particles to relate to chemical reactions and specifically equilibrium. Thanks for watching.


What's going on guys big Dave here at the surf station today. We're going to talk about Ben So Finns can make a huge difference in how you ride your board day to day Depending on the type of wave you have really should determine what type of Finns you ride So if you're just surfing normal all-around type of board that you just need a fin That's going to work every day from FCS to you're going to want to ride the performers These bad boys are really meant to work in all types of conditions Say well balanced all around not too raked back not too upright They're going to work in just about any conditions you want to go these are for your basically your starting point for all Finns If you're not really sure what you want to ride the performer is the best place to start If you know you're going to be surfing a lot of beach breaks real Pocketed up wedgie waves the reactor is the way you want to go These fins are a little less raked out a lot less tip to make them really good for tight turns and release in the pocket These fins are great Like I said and a type of beach breaky wave where you want to be able to drive up speed really quickly and get a lot of Release at the end if that's the type of wave you're normally on the reactors are going to be the way to go for you If you're more into surfing big walled up powerful waves and doing big turns The carvers are going to be more where it's at for you These fins have a lot more rake to them make them so they hold well through big open-faced turns They really excel well when you're surfing waves in the head to head hot plus type of waves So if you're surfing more point breaks and reefs the carvers are where it's at if you're surfing really kind of Hollow reef break point breaky types of waves the accelerator is where it's at These fins are gonna be great to give you a lot of speed down the line But still great when you want to go for a real aggressive hard turn They're gonna hold really really well because I have a bigger kind of oversized template to them These fins are great like I said and kind of reef breaky hollow waves or long walled up point breaks All right guys if you have any questions feel free to hit us up at support at surf dash station calm Or give us a call at<PHONE_NUMBER> Thanks for chatting with us today


Hello everybody and welcome back to the Earthridge. I got this mail in the post basically after the success of this video that I made with the Mia wash paints the company decided to send me a bunch of random art supplies that they Recommend and I was like heck. Yeah, give me some free art supplies So I'm gonna test them out and let you know my honest opinion on them And let's see what they gave me. Hopefully they sent me some good stuff. Pesto's here by the way She always comes here when I film because I think she thinks I'm talking to her. Also, there's a box here So she's gonna be like what's in there? Excuse me? Yes, you're very cute. Well done. No, okay, so let's see what we've got Oh and straight away I can already see that we've got some acrylic paint markers, which look awesome and They're non-toxic acrylic paint water-based, which is really cool and look we've got so many colors These are obviously contenders for Posca or the Molotow pens, so it'd be good to compare them They do have some very nice pastel colors here Which I'm excited to try and looks like they have a gold shimmer and a silver metallic one We also have these same similar feel of water-based non-toxic pens, which are metallic, which is interesting Well, those look really nice. I really like the packaging And look they've got like nice postcard. These are really cool Yeah, it looks like you've got a couple of duplicates though Like these colors look the same as those double of pens. It's not really a problem, is it? Hopefully they good And lastly we've got some oh not lastly. Oh, we've got some watercolor brush markers out I've used these before not this brand and I really like them. So let's let's get trying these out Look got loads of different colors, which is really cool Pesto, you need to calm down. I'm looking forward to trying these I can't believe somebody just sent me loads of art supplies for free. This is really exciting Poor Rubens watercolor sheets. So this is Very nice. I've seen this before advertised and I was thinking about buying it myself This is really nice to receive. That's awesome. This is 20 sheets, 300 gsm Which obviously the water retention that can take it's a watercolor block So it can take a lot of watercolor and these are the things that we've got and pesto Really likes them. So let's get trying them out. Shall we I really this is probably the thing I'm most excited about the paint pens and then what else and The sketchbook, maybe these are like really interesting items and I will definitely give them all but this is the main game for me Right now, so I'm gonna try them out once pesto has it out So let's get started Right, so first of all I decided to use the new sketchbook because I thought about using my sketchbook that I've just started But I thought it would make sense to use all the items that they gave me together to try out because a lot of these art supplies Are water-based it made sense to use this watercolor paper This had some ridges in it So you could tear it like a postcard which I found was really interesting and fun You can just rip out these pages, but also It's not like an annoying some people might not find that annoying but they have a spiral bound sketchbook I don't really like that because when you if you ever want to take the pages out Then you have all those marks. I guess you could cut it off But I don't know it's just something that I don't really find that pleasing But if you like that you like that This is interesting because you can just tear it out and it looks about the size of a postcard And you can probably send it off to people or frame it quite easily and I don't know I just I like that little aspect of this sketchbook and I think it was really useful The paint pens are really nice They were a lot more watery than I'm used to and seemed quite different to the molotow and Posca pens although the colors match was very similar to a molotow pen that I had which I found Interesting to say the least because it's just the two dark greens. They completely matched each other Which was quite nice I guess it's kind of a dupe if you wanted to get these paint pens Like the molotow ones. They are probably about a third of the cost So these paint pens retail for about 23 pounds, which I assume is about less than 30 dollars Possibly more. I'm not quite sure. That's super cheap for 24 of the paint pens It's less than a dollar each for each paint pen Which is surprisingly cheap compared to its Competitors really the main thing that I noticed about these paint pens was that they were quite watery But I think that they worked well. They took a longer time to dry That's for sure then the Posca's or the molotow But they did the job. So, you know, if you're on a bit of a budget, I really like the way that they look They're really satisfying with their like see-through case And I don't know it's just something about the packaging of this pen that is quite nice And yeah, some of the paint was a little bit separated in some of them But I think if you just mix them up, they were fine And I just watched them out to have a little bit of a go at them and decided to just go ahead and paint something Like I would normally do with the Posca or the molotow. I just wanted to paint a well draw paint a quick scene And I decided on this mountain-esque scene with a yellow house in the background Because I think it would give me a good chance to layer these paint pens A really useful thing about these is that they are really opaque So layering them is one of its main one of the main features of paint pens and this sketchbook is quite a thick Substantial paper so it should have been able to take it take all this ink and paint and it did it really did The sketchbook works really well at holding material One thing I would say about these paint pens is that they do leave a bit of a texture But I think that's might be a little bit unavoidable with the use of acrylics in a pen You're probably gonna have a little bit of texture, but hey if you like texture in your work Then maybe that will help you here I am trying to layer all the paint down and the yellow I had a hard time Layering because it was very it was a little bit thin So I had to do a few layers of it But then it wouldn't dry fully I had to keep trying to layer stuff down and being impatient like I am I don't think I waited enough time for each layer to dry So each time I tried to put a new paint down on top of the yellow It kind of smudged a little bit and didn't really work I do go back in later like I've filmed this over a span of a few days and it did work So it just needs time to dry I think a little bit more time than my impatient persona can handle So that's the only downfall of these pens But as you can see I went back in with other colors and I layered them quite well There's light colors working over dark colors, so they do work It's just that you have to be more patient with the material and that's basically it I guess you get what you pay for so if you pay a third of the price Then you're going to be sacrificing something in that area But yeah, they worked out all right and that's the finished piece that I came up with for them Next up is the watercolor brush markers Now I have used watercolor brush markers before But I have not used these companies before And yeah, they came in this massive stack of different colors Which I found quite overwhelming at first because there was 48 of these colors And they are priced at £17, which is probably about $20 So again, pretty good price for what they are And already I just tested these out and I found out that these Watercolors are basically what they say on the tin They are watercolor pens and I found it really nice because I've tried watercolor pens before And where they've been like quite nice and flowing and juicy as we say These ones were just even more so like they were very watercolor-y Like when I put the color down on the paper It felt like I was actually painting with watercolors in the sense of the way that they looked They looked like I had taken a brush and I had layered it down with a brush And I found that really, really nice They were just really convenient and useful I can see taking these on holiday or going outside and drawing with them a little bit more They take a little bit longer than they would to just actually watercolor Because you were just coloring in with pens really But they have a really nice effect and quality to them that you can't really deny And I think it works really well because they blend with each other They take a while to dry like the paint pens But I think it works to its advantage Because you can take moments of blending them atop of one another Like you would with real watercolors And I think it gives that aesthetic of actually being painted with a brush and water And that's pretty pretty cool considering their pens I would say that the barrel of these pens feels a little bit flimsy But then again like I said before with the paint pens When you sacrifice with price you get something in return that isn't perfect But it's still really good and I think these are really affordable Really nice watercolor pens if you want to try some out I think these are pretty good I really enjoyed making this piece as well I just decided to draw a woman looking up at the sky Because I'm obviously myself dreaming of a holiday And I was just imagining what it would be like to just be in this beautiful blue ocean And I wanted to do something with water Because I knew I wanted to blend a lot of different colors into each other And it just makes sense with water And at least I hope it makes sense Maybe it doesn't make sense to anyone I think what happened with these colors though Is that when I looked at them in the box I felt a bit overwhelmed because there were just so many colors I was like I don't know what to use And just looking at the bottom of the colors didn't really give me any inspiration It wasn't easy to just pick out colors So what I did is I separated all the colors around my desk Into their different groups Like the blue, gray, greens, pinky, oranges, purples and browns And I think that really helped me to decipher where I was going with this image Because I was like okay this blue and then this blue And I liked that they had an array of colors within color groups Because then I could pick up a blue And then I could use a slightly lighter blue and fade it out a little bit And I really liked that idea of using a dark color And then sort of blending it out with a lighter color Now obviously you do run the risk of staining the tip of the lighter color pen But actually they kind of lean themselves as you go along with it And I thought this was really nice And I thought they worked really well Especially considering they are only 17 pounds Which is crazy to me Next up I wanted to use the metallic pens I've never really been a huge fan of metallicy things Like paints and stuff I've just never really been interested in them I like glitter and things But I'm never sure on how to use them within my paintings So I was a bit unsure of how to add this Or even if I was going to do a separate piece But then I decided to just give them a whirl And try them out in this sketchbook Because I thought let's see how they mix together with the watercolor I also used a bit of white paint pen in this image as well Because that's how I work So I think it was useful to see how these art supplies would work with each other And I think they worked really well I'm surprised by the metallic pens They're super opaque and they were super satisfying So I had to keep coloring Finger made a bit of a mistake Coloring the front of her face with the metallic Because it looks a bit odd But I wanted to use it as a bit of a highlighter pen As in makeup highlighter, not a highlighter And yeah, it turned out alright in the end I think it's a nice painting It's really cute Um, and I really like the art supplies That's it And I was actually really shocked by the metallic paints Because like I said, I'm not a huge metallic person I don't really know how to use metallic art supplies within pieces But I think this pulled it off Because it just gave the character a bit of a shine As if she's in this sparkling water And I really like that effect So these are all of art texts I think that's how you say their company name Is art supplies And yeah, I think definitely The watercolor pens were a bit of a surprise for me Because I was more excited about the paint pens But I think I really preferred using the watercolor pens The best And then the metallic pens, I just, yeah Generally everything pretty good And pretty cheap So there you go I don't know Like I think these are pretty cool So I wouldn't hesitate to get some more of these things Once I run out Unless I get some more stuff for free Which is, it's honestly crazy I didn't expect ever to get to the stage Where art companies would send me stuff So I'm actually really appreciative of it And I really appreciate you guys All your support and everything Because it wasn't for you guys I wouldn't be getting this stuff So thank you And I hope that these reviews and tour Helped you out in some way Obviously, again, I just want to say Don't buy this stuff Just because I have it But if you want it, there it is And again, as always Thanks for watching guys And I will see you next time Bye


Hello, my name is JT Williams and this is my book, A Story of Stories or Why I Write. There once was a child, a curious girl, who loved reading stories. Her books were her world. The library she'd visit with dad once a week and there in those quiet rooms knew tales she would seek. And when she had chosen a new book to read, she'd carry it home, a prize, precious indeed. And comfortably into a corner she'd sink to ponder its pages, to listen, to think. Like wings the words soared as they bore her away, to fantastical places each night, each bright day. In her mind she would travel to worlds near and far, her route was the ocean, her ship was a star. Of forests and rivers and magic she read, the tales of the living, the myths of the dead. Of giants and children and witches and queens, of creatures with voices of magic unseen. But as she grew older, the stories she craved were those of her own world, her home life, her days. She yearned now to learn of the person she'd be, the challenges waiting, the future she'd see. But the stories she wished for, the ones with her in, had not yet been written, had not yet been seen. So where would she find them, these tales of her life, of her friends and her family, her joys and her strife? It was she who must tell them, it was she who must write the books that she needed, her words must take flight. She thought and she wondered, she dreamed and she penned the tale of her childhood from beginning to end. Now others could read it, this book all her own she had shared with the world. And by skimming this stone, by sharing her story for others to read, she had made a connection, she had planted a seed. A book is a journey, a learning, a spell, a space to get lost in, a deep place to dwell, a comfort, a challenge, a mystery, a thrill, a long conversation, a climb up a hill. To read is a wonder, a magic our own, a way of communing when we are alone. Each book can transform us, each story we know, breathes life into us and helps us to grow. So visit your library, take time out to choose the stories you wish for, the books where you'll lose yourself in the pages and perhaps find yourself too. Who knows just which book will be perfect for you and if you can't find it then maybe it's time to create your own story or poem or rhyme or lyric or folktale or drama or song whatever you write. There's no right or wrong. So what will your book be? What words will you choose? What pictures will grace it? What tools will you use? You might write with a friend or you may work alone but have fun as you now make a book of your own. Thank you.


This paper presents a process-oriented approach to developing and evaluating Facebook campaigns for recruiting rural adults into healthcare delivery interventions. 2 case studies are used to demonstrate the effectiveness of this approach. The authors found that Facebook was an effective and affordable way to reach rural adults and successfully enroll them in behavioral research studies on tobacco and mental health. This process can be applied to other study topics and further evaluated to determine which specific message features are most effective for recruitment. This article was authored by Elizabeth Floodgradey, Devin Huff, Rachel E. Domione and others.


Vakaduna State Government has directed all political appointees and public servants aspiring for political offices in the 2023 general elections to resign on or before March 31st of 2022. This directive is contained in a statement issued by the Secretary to the State Government, Balarabe Abbas, who confirmed that the directive is in conformity with the 2022 electoral act recently signed by President Mohammad Abu Hari. The 2022 electoral act specifies that such officers should resign from office 30 days before the party primaries for the post for which they are aspiring. Well, we are now being joined by Mr. Johnson Argo, a legal practitioner. You are welcome to the news. Thank you, Maureen. Well, section 84, subsection 12 of the amended electoral act has been so controversial. Do you think that there are some vested interests in this? Of course, politics is a game of interest. A lot of people want to have what they prefer on the ground. Why they prefer what they prefer? Most of the times are best known to them, even though we prefer that the reason why they prefer whatever they prefer should be in the interest of the general public. Well, even after signing the bill, the President has categorically inserted the National Assembly to delete it. How constitutional is this? No, the President cannot dictate. He can't suggest. But the National Assembly has to make laws in the best interest of the nation. Well, this very section that is requiring them to, well, asking a certain section of the people to resign 30 days before indicating interest, you know, that's if they have interest to run. How democratic would you say it is? I think it is. If you look at the constitution, it has already provided that public officers or public servants should resign 30 days before the election they want to participate in. If you want to participate as a Senate or as a House of Representatives member, as a President, as a Governor, as a House of Assembly member, you have to resign. Assuming you are a public officer or public servant, various sections of the constitution make this provision. So it's already there that you have to resign. What this new electoral act amendment has just done is to expand it from just being public servants to political appointees. So political appointees are people of my public officers are supposed to public servants. Now, there's nothing overly wrong with it. We might say it restricts political participation, where it forces somebody who thinks he wants to participate in a political position to resign ahead of time. It's probably, we can say it's a legislative ad hominem, targeted at a particular group of people. You might say so, but I think it's something in the interest of democracy because it creates a level playing ground. Everybody is, let me say, nobody's afraid that a political office occupier like the Governor can determine the outcome of electoral primaries. Well, for example, our experience now is that Governors determine who the candidates are. How do they do that? They overload the political appointive positions. They can have as much as 1000 appointees and start to trailing, quote, in most parties. They have, they become delegates for primaries. So whoever the Governor dictates should be the candidate of any particular position, the delegates will vote for that person. That doesn't make for free and fair elections. In fact, that system already means a rigged system. I, or any person who is ordinary, who does not want to pay homage to a political elected executive, we definitely do not have a chance to win primaries. You know, I'm still thinking, this asking people to resign 30 days, isn't it such a high risk?  Because they seem to drop everything in there and so they must get it at all means. It's like there is no option. That risk is there, but I think it's a lesser risk. It's less of the two evils. When you have, when you're faced with the devil and probably deep you see, you choose what you want to do. Do you want to drown? Do you want to meet the devil? Do you have a chance at winning the devil? What if you escape altogether? How can you escape? So I think that is the option Nigeria has checked.  Although we don't call brand names because they've not paid for ad, but we get what you're trying to say. Now has this been abused in the past by politicians, this particular clause? Of course. Because as you've rightly indicated, it's not new, it's just been broadened. Has it been abused in the past? Can we have instances if possible? There have been instances where appointees were expected or let me say office holders, but civil servants mainly, were not able to resign before time and it became litigous, but it wasn't that notable. And in the present instance, they have been told you cannot use office resources to beef up your chances because if you remain in office close to the electoral time, there are risks that you can offer patronages as make promises on the basis of public covers, public posts to people for them to vote. You probably influence the outcome of election because of the picks of office you can offer. So by removing that from view, you have been made as normal as any other contestant. And that's what I call equality. Equality is very key in any democracy. If you want democracy to really be what it should be, people being free to choose for themselves who should lead them, there should be equality. And that is what I think this provision has engendered. Mr. Johnson, I think this is a good place to stop this conversation. Thank you so much for your time and insight.

Welcome back, we are studying the Jacobi symbol which is a generalization of the Legendre symbol. So, remember that we had the notation a by n, a can be n a integer, n is a natural number to begin with. And then we define this Jacobi symbol a by n by using the prime factorization of n.  This was our definition of the Legendre Jacobi symbol. And then we saw that there were several properties that the Jacobi symbol satisfied in line with the Legendre symbol the most important of those where the quadratic reciprocity laws which are here in front of you in this slide. So, we have that minus 1 power minus 1 sub n the Jacobi symbol is equal to minus 1 to the power n minus 1 by 2. So, the Jacobi symbol can be computed for minus 1 in the line with the computation for the Legendre symbol. If n is odd then 2 by n has the same formula as was in the prime modulus case in the Legendre symbol case that the Jacobi symbol 2 by n is congruent to minus 1 is equal to minus 1 to the power n square minus 1 upon 8. And finally, we have that whenever m and n are odd integers odd numbers natural numbers then m by n and n by m satisfy this generalized reciprocity law. So, these three properties can be proved using the similar properties for the Legendre symbol. So, we are not going to give their proofs. However, note that for minus 1 we have used the Euler criterion.  So, that Euler criterion which was true for any integer a provided your modulus was a prime p now need not be true for the Jacobi symbol in general. So, the Jacobi symbol does not satisfy Euler's criterion which is to say that these two numbers the Jacobi symbol value a upon n and the value a power n minus 1 by 2 they need not be same and they need not even be same modulo n. So, of course, we see here that a by n has the value 0, 1 or minus 1 and a power something is going to be much bigger if a is positive or it will be on the negative side if a is negative. So, we cannot hope these numbers to be same but these are not even same modulo the number n. For instance you may take a to be 8 and n to be 21 and you can check that these two numbers 8 by 21 and 8 power 21 minus 1 by 2 which is 8 power 10 these are not same modulo 21. So, this is a failure of the Euler's criterion in general for Jacobi symbol. However, mathematicians have a knack of turning failures into very useful things. So, this failure of the Euler's criterion in the case of Jacobi symbol can be used very effectively when we are doing primality tests. So, this is useful in several in fact it may be called the basis of primality tests for several of them. So, how do we go about this?  So, you want to check the primality of this natural number n. Then what you do is the following thing that we then check whether the Jacobi symbol satisfies Euler's criterion for some random integer a. So, now you may ask whether we can compute the Jacobi symbol without knowing the factorization of n remember we are going to test the integer n for primality. So, we do not know whether n has a factorization or not if we already knew that n has a factorization then we would not need to check n for primality. However, we can use quadratic reciprocity laws the analogs of the reciprocity laws to compute a by n without knowing the prime factorization of n. That is where those analogs of the reciprocity laws are useful. So, we will compute the Jacobi symbol a by n without knowing the prime factorization of n we will then also compute a power n minus 1 by 2. Computing powers of some certain integer is not a very difficult thing for a computer. So, what the computer does is that it can quickly compute various squares. So, if you are given a it will compute a square it will compute the square of a square which is a power 4 it can compute a power 8 a power 16 and then whenever you want to compute any power of a you have to take product of these various squares that you have computed in a suitable order. If you wanted to compute a cube then you have to take product of a with a square if you want to take a power 15 then you should take product of a a square a power 4 and a power 8 because 8 plus 4 plus 2 plus 1 will give you 15. So, computing powers is a relatively simpler thing when you are using computers and similarly computing congruences is also a relatively simpler thing. So, number one is that you can compute Jacobi symbol using the reciprocity laws, number two is that you can compute powers of a and go modulo n and then you simply check whether these two quantities are the same. So, what we do is that we compute the Jacobi symbol and see whether the Jacobi symbol a by n satisfies Euler's criterion for this integer a, this is a randomly chosen integer a. If it does not then n is not a prime because the prime modulus case will give you Legendre symbol and Legendre symbol does satisfy Euler's criterion. So, if a by n is not congruent to a power n minus 1 by 2 modulo n then n cannot be a prime. So, this is a very nice primality test. However, unfortunately you may happen to choose a for which the Euler's criterion may hold. Can we then say that n is a prime? No, but what we will then say is that n is probably a prime. So, this is where advanced things among primality tests come into the picture. So, the tests will tell you how many integers you should check for how long you should go checking meaning if you start from 1, the most natural thing is to check the Euler's criterion for a equal to 2. If that holds then those numbers have some certain names then you will check for any a equal to 3 and so on. So, how far do you need to go to check these criterion and this is where some probabilistic things will come into picture that when can you see that it is a prime by what probability and so on. So, these are the things which do not come into our syllabus and we will not discuss. However, I just want to add one more thing. So, we started with Legendre symbol which was a by p where a was any integer and p was a prime number. Then we went to Jacobi symbol where which was denoted by a by n, a is any integer and n is a natural number and there is a slight generalization of this which is called Kronecker symbol. So, there is this mathematician Kronecker in the 19th century who introduced this symbol where you allow n also to be any integer, non-zero integer. If n is 0 then there is some certain value which we take by convention. So, the Legendre symbol, Jacobi symbol and Kronecker symbol can be studied and there are relations of these with some character values the Dirichlet L function and so on which we are not going to discuss in this course. So, with this we come to the end of our third theme which is broadly called the theme of quadratic residues where we determined whether a certain integer is a square modulo a prime p or not using various other things. We were able to compute it very effectively for many primes and many integers then we generalized the Legendre symbol to the Jacobi symbol and we saw an application of the Jacobi symbol in the primality tests. Our next theme is a very interesting theme it is on binary quadratic forms. So, this is a slight generalization of what we were studying in the last theme. So, remember last theme started with finding equations solutions to the quadratic equations. So, these were equations in one variable now we are going to take two variables. So, we consider binary quadratic forms over integers which means that we are going to take these expressions. So, here we have so let us start noting various things we have two variables now x and y and this is why we call them binary. So, the name binary comes because we have two variables namely x and y quadratic comes because the degree of the polynomial here is 2 and form comes because the polynomial is a homogeneous polynomial and where do integers come? Integers are there because the coefficients of this polynomial are taken from integers. So, these things therefore as you would expect are true in more generality you can take forms not necessarily quadratic but you can take cubic forms, quadratic forms, quintic forms and so on. You may take binary forms, ternary forms, quaternary forms and higher number of variables in the forms and you may take them over not necessarily over the set of integers you may take them over a general sets. What we are then going to do is to evaluate these forms. So, here since we have taken a, b, c to be integers we will be easily able to put values for x and y from the set of integers and compute the value. So, when you take a, b, c from a general set a set general than integers we expect that the set be such that you can take products over the set you can take additions over the set and so on. So, this is the structure what is called a ring. We have earlier studied this structure called a group and we saw some applications of that here we will not use but let me just tell you that you can take forms the generalized versions of these forms over rings. So, here we are going to take them over the ring of integers. So, we have this set z of integers which is a ring and over these ring of integers we are going to take binary quadratic forms. We are not going to take higher order forms, we are not going to take forms in higher number of variables. These are enough for us, these are going to give us lot of interesting properties. So, at the moment these are quite good for us. So, these are the forms that we are going to study and given any such form f the thing that we would like to compute is the set of values taken by this form f. So, given any such form what we are interested in computing is the set of values f, m, n where m, n are integers. So, these are the numbers that we want to compute. So, not one number that would be a very easy thing if I want to just compute f of 0 0 that would give me 0 it is a homogeneous form.  So, those are easier things but I would like to compute the set of values where m and n are taken to be all integers. This is the set that I would like to compute. Now it is quite possible that you may have two different looking forms and the set of values given by them may turn out to be the same sets. So, this can actually happen many times it happens quite often. So, there might be several different forms which may have the same value sets and an example can be readily given. You may take these forms. So, these are three forms the first form is f of x comma y equal to x square there is no x y term there is no y square term. So, the coefficients b and c are both 0 but we have the form to be x square. So, you are going to get all squares whenever you put value for x any integer in the place of x you are going to get the square of that integer. So, all squares are represented and the whole set of values is the set of squares. Similarly, the second form that you see here is nothing but x plus y whole square. So, once again whatever value of x and y you choose the value of the form is a square and you can put y equal to 0 and x to be any integer and all squares are represented. So, the value set is the same as the set of squares. Similarly, this is x minus y whole square. So, it is the same computation. So, these are three different forms and even then we have that their value sets are the same. So, what we would like to do is to put some kind of equivalence relation on the set of binary quadratic forms. So, I will not keep mentioning the word binary or sometimes I will even forget to use the word quadratic but we should remember that we are always going to look at binary quadratic forms over integers. So, we are going to look at homogeneous polynomials of degree 2 into variables with coefficients coming from the set of integers. So, we are looking at these forms and we would like to say that in some way one form is equivalent to another form. So, we will try to put some relation between these calling some of two of them to be related to each other or if you have all the properties then the form then the relation will be an equivalence relation. So, one form will be equivalent to another form and we would also try to have this transformation the relation so that the value sets turn out to be the same. So, what we will then do is that whenever we want to compute the value set of a given quadratic form the given binary quadratic form which may look difficult because a, b and c might be big numbers they might come from different signs and so it may happen that computing values by hand might be very different, very difficult. So, we would then transform it to a simpler looking form and once you transform it to a simpler looking form then we may be able to compute the value set more easily and if you also have that this transformation keeps the same value sets then you would have computed the value set of your earlier form this is what we are going to do. We will also have some certain invariance associated to these quadratic forms. So, what do you mean by invariant? By invariant we mean that when you apply the transformations mentioned in the previous lines these are the quantities which do not change. So, these invariants which do not change and hence they are called invariants when we apply these transformations. So, these are the things that we hope to do. Number one is that we will say that one form is equivalent to another form or one form form is obtained from another form by some way. So, we will give these transformations we will go we will give a method to go from one quadratic form to another quadratic form without changing the value set and there we would also like to have this way to be invertible because I do not always know that I am going to go from a difficult form to a simpler form by this way. It may happen that you start with a simpler form apply the transformation and you may get a difficult form. So, the transformation should not be only one way it should be both ways it should be an invertible transformation. So, we will see that there is a way to define this transformation we will see that there is a relation that you can put on the set of binary quadratic forms which will also help you compute the value sets. So, this is what we are going to do. So, here comes the definition let us start with two forms two binary quadratic forms. So, you have the form f and you have the form g. So, suppose your form f is given by a b c and g is given by a prime b prime and c prime. So, we say that these two forms are equivalent if one of these can be obtained from the other using the substitution x equal to p x prime plus q y prime and y equal to r x prime plus s y prime. Here we have that these p q r s they are integers but this is a very important condition that p s minus q r has to be 1. So, you may have your form f which is given in terms of x and y. So, you have f equal to a x square plus b x y plus c y square. Now, if you put instead of x the value p x prime plus q y prime and instead of y the value r x prime plus s y prime then you are going to get some expression in x prime and y prime which will remain to be homogeneous of degree 2 because our substitution is homogeneous of degree 1. Here we had degree of x to be 1 degree of x prime to be 1 and degree of y prime to be 1. So, we are considering x prime and y prime to be new variables and we are writing x and y in terms of these new variables and the substitution is homogeneous of degree 1. Therefore, the ultimate expression that f will change to will continue to be homogeneous it will continue to be of degree 2 because there is no change of degree. So, you will get a different expression.  So, this will be some a prime x prime square plus b prime x prime y prime plus c prime y prime square. This is our form g. So, when you started with f and instead of x and y we put these substitutions in terms of x prime and y prime. If we get the form g in x prime and y prime then we say that f and g are equivalent. Now notice that in this definition we did not say that you have to obtain g from f or that you have to obtain f from g. It can be that one is obtained from the other. So, it is clearly this relation of f and g is clearly a reflexive relation whenever f is equivalent to g, g is equivalent to f. This is by definition. Further you will see that the form f is equivalent to itself because you can take p to be 1, q to be 0, r to be 0 and s to be 1. So, if you take p equal to s equal to 1, q equal to r equal to 0, you are going to get p s minus q r to be 1 and you are going to get same thing. You are going to get x equal to x prime y equal to y prime. So, the form f is equivalent to itself. The form f is equivalent to g then g is equivalent to f. That is a slightly non-trivial thing. We will see that in a moment. But more importantly whenever f is equivalent to g and suppose g is equivalent to a third form h then f is equivalent to h. So, all these three properties are put together in a box and we call them an equivalence relation. So, we see that this relation is an equivalence relation. That means the relation satisfies reflexivity, symmetry and transitivity. So, this is of course an equivalence relation and further the value sets of f and g remain the same. So, we will see this in our next lecture which we will continue on the same theme. So, I hope to see you in that lecture also. Thank you.
