This beautiful song sounds even more beautiful when it's accompanied by harmonium. Of course I didn't play the harmonium because I do know how to play the harmonium. I was afraid to record it and then I voiced over that recording. But I want to talk about these white and black keys. What are these keys? You know they correspond to notes A, B, C, D, E, F or Sari, Amaka as they are calling Indian classical music. But what are these notes? What is the physics of these notes? And what is the physics of music? The word harmonium is reminiscent of the English word harmonic which we see in physics, in simple harmonic motion. And this word is also related to the word harmony which we use in general to refer to different parts of the society working together to create something. In all these senses, harmony refers to one thing and that is fitting together. If we have a rectangle at several small squares, if all these squares are together exactly fit inside the rectangle, we say that the rectangle and the squares are harmonium. And if there is some part of rectangle or square left over, we say that they are not harmonic with each other. What does this have to do with simple harmonic motion? You see, simple harmonic motion is a sine or a cos function of time. And sine and cos are called circular harmonics. Why aren't they called circular harmonics? You must have seen the diagram where sine is represented as the length of the chord of a circle, half chord length of a circle. Now this chord length increases and decreases sometimes positive, sometimes negative. But overall, it completes one cycle or one loop along with the circle. In other words, a circle, the completion of a circle and the completion of one period of sine and cos fit together. That is why they are called harmonics, therefore circular harmonics. Because the nature of the function is in harmony with the circle. When you complete a whole circle, the function begins to repeat itself. In college level physics, we have spherical harmonics, which are harmonics over a sphere. These are polynomials in terms of force theta, which are synchronized with the sphere. As you complete a closed loop on the sphere, these harmonic functions also complete one cycle of their matrix. Therefore, circular harmonics and the word harmony of fitting together and working together are closely related. So now that you know that harmonics are used in society or harmony in the sense of fitting in of different people together. And they are using physics to represent a function that fits into the shape of a circle, by completing one period of values every time the circle completes one rotation. We now look at why harmonics are used in music. Why is this instrument called the harmonium? What exactly fits in into the different parts of the harmony? You see, first I will give you the physical fitting in sense, in terms of what you can hear. And then I will tell you what is the physics behind it, what exactly fits in mathematically to develop this harmony. I am going to press a note that represents the classical note sum. This will play a harmonium sound of sum, but I am going to match that sum with my voice. And you will notice that if I match it properly, then you will be able to hear a certain resonance between my voice and the speaker. However, I will be able to match my voice to this note of sum in two different ways. So, way one, here we go. Voice to this music in two different ways. Just to give you an illustration of matching, I will now show you a note that does not match with sum. You can see that my voice does not fit in with this and it feels weird. But when I matched my voice to the note, it was clearly audible as a result of resonance between the speaker and my voice. So, harmony is a fitting in of sound notes. So far, what I have demonstrated to you is a sense, an intuition of how it feels when two notes fit together. But what exactly is fitting in this note? In order to know that, we need to look at strength. Practically, we need to generate waves, these waves on a string. When you take a string, this traveling motion of the string is called a wave. What waves and strings have to do with sound and music? You see, sound also is a wave. And strings are a great analogy to understand how sound waves work. Look at this string. I can move this string around in such a way that it forms a groove, something like this. You can see my hands at the end of the string are not yet moving much and the center of the string is moving a lot. I can do the same thing. I can move the string without moving my hands very much. But I can generate two loops of the string. You can see that the ends of the string are largely constantly in place. And the center of the string is also constantly in place. And the string is actually moving in two loops. Now, what is happening to the string as we increase the number of loops? You see, when I rotate the string in one loop, one exact rotation, one exact bit of string that is vibrating is fitting inside the loop. When I rotate the string in two loops, two exact segments of the string vibrating are fitting in the total distance between my hands. So strings vibrating in loops are related to fitting in of harmonics. The word harmonic is related to fitting in and strings vibrating in loops are required to vibrate in such a way that the ends are fixed and there is a fitted number of loops in between those ends. In other words, I can vibrate the string in one loop. I can vibrate it in two loops, three loops or four loops. But I cannot vibrate a string in one and a half loop. And therefore the number of loops in the string would have to fit exactly in the distance between my hands. That is why strings are related to harmonics. Because vibration of a string or rotation of a string is a harmonic process where loops are supposed to fit exactly into the distance between my hands. My hands are called nodes and the points that are stationary in between the string are also nodes. Therefore movement of the string is the fitting of a fixed number of loops, a whole number of loops in between the end nodes which represent my hands. Now we address the question of how sound ties into all of this. You see sound also can be represented mathematically as something akin to the vibrating string which I just showed you. If this y-axis represents the pressure of air and the horizontal line represents the position in the column of a flute or in the blow of a harmonium, the position in a musical instrument, then the graph of pressure versus position is going to look just like the string where these are end points of the instrument. The vibrating pressure of air inside the musical instrument can form two loops like I have found here. It may form three loops, it may form a single loop or it may form any number of loops. But it will have to form a fixed number of loops because the treasured at the two ends are fixed. You see this end is open to the atmosphere which means it must be at a fixed pressure, the atmospheric pressure. This act is open to our lungs and this must be fixed at the pressure at which we are insulating air. Therefore the pressure cannot move at these two positions and it is in this intermediate position that the pressure is allowed to form loops and these loops must fit in, a whole number of these loops must fit in to the gap between these two end points. That is why sound is similar to the vibration of a string which I just showed you. You see each number of loops fitting into the distance between the end points, each number of loops is called a harmonic because it is a particular way to fit in the loops into the distance. Different harmonics vibrate at different frequencies while frequency is the number of vibrations per second. Different harmonics vibrate at different frequencies and these different frequencies are called notes. The musical note's different pitch and the quality of a wave which causes us to experience different pitches for different waves is frequency. Frequency is dependent on the number of loops fitting in between two fixed points and therefore changing the number of loops or changing the harmonic of the musical instrument of the air vibrating inside the musical instrument gives us a change in the pitch which we perceive as musical notes. And what was I doing earlier? Singing the same note in two different ways to match my voice with that of the harmonium. You see initially I was singing my note and perhaps there were 50 loops vibrating in my open pots between my lungs and my mouth. When I sang the note again this number was changed by a certain fixed percent, maybe it was 75 loops more and that gave me the next note, the next pitch or the next frequency which is a fixed number of loops between the same two points. And that is why I was able to match my voice in two different ways with the sound of the harmonium.


Hi, digits. So it's been a minute since I've recorded something on this bed I've kind of evolved my content, you know Now I do videos on the floor on the piano in my kitchen, but I wanted to return to my roots today because There's this app online It's called lucky for all of you who don't know and I know lately It's been a trend finding your celebrity match or whatever So my friends were doing that and I wanted to be a relatable person So I tried it and I did it about three times before I verbally screamed at them because Let me just show you here's the video basically It's impossible for me to find something that looks remotely like me and I wanted video proof because everyone says I look like Eugene Lee Yang and I'm ready to put that to an end. Okay, so we're gonna add a photo take a beautiful picture of me Yes, I have acne shut up about it Also, I just want to say they make you watch and add every goddamn time and frankly I don't have the patience for that. So let's see what my match is first picture. I just want to know hmm He's not Asian, but I mean he does have cool hair But I am not Caucasian unfortunately. Let me just redo this one more time. Okay, trust me There's a process that goes on in this video It gets worse.  Sorry guys? I forgot a screenshot that part of the video. Um, hello This is an unprofessional friend trick. Why do you watch me? But I just wanted to show y'all the extent of the women that I got motherfucking lady Gaga them got Ruth B And then see ya See ya a blonde female who barely shows her face. So I don't know how she's a match Back to the video. I'm not a woman actually it may be surprising to you, but I'm actually a man This is just a little bit of shade from this app. All right, what if I take something from my albums where I look decent? I'm gonna take this picture. Okay, this picture right here that has my full face in it and my smile It should work and a 30 second ad. Oh my god, please Finish Two Please help me. Okay. All right. Um This motherfucking app thought I was black. Um, I don't really have words. I mean I'm tan. I just want to look at some more results of who I could be. Oh another black guy very nice That's what I was looking for another black guy.  I feel so honored. All right All right, finally we're getting closer the sex is wrong first of all, but like She's an Asian. You know what maybe maybe need to wear glasses. You all know I wear fake glasses more than half of the time So maybe this will help Find a match watch a video die more on the inside I want you to know I got Mariah Carey as an option the first time and I wish I recorded that. All right Another white person. I'm down with that. Let's look at more results So I can you know have some hope in finding an Asian man who looks like me This either shows that one my face isn't meant for photos or two There's not many Asian celebrities in pop culture And that's a problem.  Um Great, okay All right, that's a white female and that is a very old male This just keeps getting better and better honestly. I mean let me know if I'm the only one here Let me just get one more photo from my albums. Let's do this one. Why not? All right.  I know and I just want to say he looks like Sid from Toy Story Tell me I'm wrong. You know what? I'm gonna take that as a compliment for once Oh my god Why are all the attractive white males being recommended to me that guy's in Gallagher from Shameless Once again, these are all white males Where is my Asian representation? That's all I wanted. Is that so hard to ask? I'm pretty sure Eugene Liang is more famous and more searched up than half of these people. What went wrong? Lookie, I just want to know. Let's do a picture of like Maybe a duck faces better. Nope. Not not getting better. Nope Just want to be Asian actually.   Let me find the most embarrassing Nasty offensive photo of myself from the past year. Wait, hold on. Let's play the game together guys Uh-huh. Oh, look at that. I found the chessboard.  I would have taken it I don't care about the stereotype anymore.  What are these results America explain So Frederick, why did you make this video? Like what is the point of this?


Welcome folks. This is Jacob Schup fill in in for Tom O'Brien. He will be back Monday Take a look what we got going on. Well, first is December. That's phenomenal We'll talk a little bit more about what we have going on here at TFNN in December Let's take a look at the markets first with the ES trading up point four two percent We have the Russell futures trading up two point three seven percent NQ's at point sixteen Dow futures at point seven. We have gold gold has made Phenomenal move recently currently trading at two thousand eighty nine dollars on the gold contract itself One of the biggest winners. We were looking at it in the den It's down a little bit today, but look at this immense move. I mean we're this is Vista gold Okay, we've we've had Fred Ernest CEO on a few times Let's take a look at this Leased on the weekly some massive movement and some pretty strong volume going up as well This stock was kind of lagging behind a little bit with the rest while the rest of the gold contract was moving up But it finally took off. So that's pretty neat to see we have silver trading it up about point seven eight percent right now copper contract up one point six two percent We have crude so there's been a lot of talk going on with crude recently Especially regarding potential cuts that OPEC plus Will be making we'll talk a little bit about it today as one of the headlines was that the OPEC plus members have agreed on additional output cuts and then so then you ask why is the Contract going down. We'll talk a little bit about what investors How they're kind of digesting that information and kind of the whole sit-rep of that situation in general We'll get to that Tesla trading about flat right now at two thirty eight Forty-four Elon made some big headlines recently Regarding his visit to Israel prior comments Regarding that situation and then what he said about Bob Iger recently Some people are considering or at least taking the kind of downtick in Disney as a kind of consequences of Elon's comments, but I'm not sure how accurate that is Needless to say Disney is trading down We were trading about at our highest here about 96 59. This was sweet Especially if you were a Disney bag holder or traveling back down here to 92 33 currently We have the dollar trading at 103 26 So some really nice down movement at least over the past month in it We had an uptick Yesterday in the day prior as well, but we'll see if we can move down here in the dollar The QQQ trading at 389 at 78 Google at 133 16 meta at 324 78 and Apple at 190 110. Alright, let's talk a little bit about the crude oil. I Smoke about I think the last time I was on or maybe two times ago how OPEC plus, you know, Saudi Arabia Was really the influencer in this But they were talking about reducing Oil output. Okay, this is obviously going to increase the prices for the rest of the world America Produces the most oil for sure. But of course, you have this whole mixed bag With with Russia, Saudi Arabia being the top three after that and then a handful of others as well This kind of obviously reduces the supply increases the price And then we're you know moving into winter In the West and so this kind of can can cause some issues essentially, right? So talk a little bit on this the OPEC plus group on Thursday agreed to additional output curbs of 1 million barrels per day OPEC plus I believe OPEC is the the Gulf nations OPEC plus I think adds Russia in Mexico and I think one more after that as well But Russia Mexico being the biggest players added in OPEC plus the OPEC plus group on Thursday agreed to additional output Curbs of 1 million barrels per day in a move aimed at sending prices higher The deeper reductions come alongside an extension of Saudi Arabia's unilateral reduction of 1 million barrels per day The move was confirmed by delegates at the meeting of the coalition of oil producers and their allies Lack of mention of additional cuts in the official press release following OPEC OPEC plus is meeting led traders So this is this is why we have some downward movement in it The lack of mention of additional cuts in the official press lease following OPEC plus is meetings Led traders believe those reductions were voluntary and not reductions to official requirements Okay, the quotas for each country announced individually. So when there was discussion before this meeting This was kind of sending the prices up a little bit Of course not too much because there's a lot of uncertainty with it And now the fact that there was not an official release it kind of has traders looking at is this really going to be a long-term thing And will it even be seen through We'll say here the West Texas intermediate futures sank more than 2% closed 7596 per barrel at the Brent crude international benchmark price settled at 8283 and Of course Brazil is also joining OPEC. I was talking a little bit about the potential for Venezuela To be joining the scene and selling their oil abroad if they could secure a safe democratic election Well, it turns out that might not happen there there is some Conflict going on with Suriname which is a neighboring country to Venezuela And I guess the government is trying to push the country into a conflict with Suriname At least that's kind of what the headlines and some of the stories lead us to believe and that would obviously Dampen kind of any expectation for Venezuela I would say getting into the the world seen in a major way and adding another producer to the market Which of course would add to supply We'll see what happens. We'll take a look today. What did I oh, yes Look at Pfizer so They were having some issues with their stock price because Covid is virtually over at least in the public perception Not as many vaccines are being purchased. They had a pop-up. I think around this day here On kind of news about a new cancer treatment Excuse me. Excuse me. Not cancer. We'll talk about that weight loss treatment. Okay, so you've been seeing a lot of companies Eli Lilly some others Pushing these kind of weight management pills, right? These are continual use pills Regardless, they got cleared for FDA use. It's like will go V For obesity management so Pfizer was pushing that they're gonna have a twice a day weight loss pill as well This kind of have a sock rebound a little bit. However, it seems that they've actually Stopped testing on it and studying on it because they're an adverse side effects Folks a two will be right back when I talk a little bit about that and also talk about some of the side effects What will go V and no those weight loss pills well folks a two will be right back
