Hi Tibees. I have watched some of your videos with interest but this one made me a subscriber. As a dad of three young girls I think you are a great role model. If you could do some videos in this style at the primary and secondary level that would be fantastic. Just a thought....
Foxlady, 4 ironic comments you don't deserve, and 566 voices do well approve your opinion. You are right : this girl is wholesome, and this makes most of viewers feeling good.
Something about the trees, the sunlight, and the birds chirping is just truly peaceful. The setting behind the content really made this more beautiful and calming overall.
We, the impoverished faceless mass of RUclips audience, hereby respectfully yet firmly demand more of such content for the redemption of our collective soul in these dark, ignorant, and brutal times. Here’s a new sub and future patron. A Mathematical day to you!
You are truly amazing. Like Feynman, you can take difficult concepts and, because you truly understand them, make them seem so simple that virtually anyone could understand them. You have a rare and precious gift. Thank you for these videos!!
What you said, that's why our schools are failing children. What you describe as her genius? That's really caring a great deal. It can't be bought or paid for and from want of it many students myself included have suffered aversion to learning certain subjects.
Yes that is what I thought of too. I am reading Feynman book The Strange Theory or Light and Matter and it has a certain way of explaining concepts that is rare to come by.
I love your presentation Tibees!! When written a little differently, Euler's Identity appears as even more awesome. e^πi + 1 = 0 This simple identity establishes a relationship between the 5 most important constants and the 3 fundamental operations, all in one single equation, with nothing in excess and nothing lacking. One can never tire of pondering this identity; it is like contemplating a bouquet of the 5 most beautiful flowers in Mathematics, arranged with extraordinary simplicity and elegance.
After thousands of videos about e^{iπ} I finally could understand the proof of it. Thank you so much!!! Being an enthusiastic of mathematics is a lot easier with you. English is not even my native language but the simplicity of this video totally overcame the linguistic barrier. Keep what you're doing girl, you're awesome :)
Melancholy Blacklite lmao, my math teacher is like robot, sits still, talks small and only repeat the definition and no explanation. We always jump right in solving equations..... 😭😭😭😭😭😭
This was absolutely mesmerizing, I have never thought math could be relaxing. If only..... ah well, high school would have been so different. Thanks for this!
And if sin jumps on top of cos, they produce a tan baby. And when the tan baby turns upside down it produces a cot for it to sleep in (which is useless since the baby is now the cot)
The great outdoors is likely where many of the ancients taught their pupils. I'm sure it made for calm and inspiring atmosphere in which to teach. We really should hold school outside on nice days.
I love to draw and I am an undergraduate physics student. Lately I was feeling a little demotivated about my course and this really lifted my spirits up! Thank you so much for your efforts! Love ya! ❤️❤️❤️
When I first saw this demonstrated, the professor started with the definition that the derivative of e^x equals e^x and developed the Taylor series from that. I remember that it "blew my mind"!
It's amazing how even after 11 years of learning this at school, I'm still able to follow what you're saying. I remember how crazy it used to be solving mathematical problems especially calculus problems given the highly competitive exams that we have in India. But after so many years, I wonder what use or benefit all this has other than academic benefits by getting good scores.
Wish I had this kind of enthusiasm for mathematics. As a 3rd year student (towards Electronics and Electricity Engineering) I do from time to time find myself amazed by the beauty of it. Really liked the way you approached that proof, if only my teachers could show it to me the way you did.
if you take the Taylor series of e^(ix) you get cos(x) + i*sin(x) now if u plug pi in there u get a creampie xDD just kidding had to write that. anyways if you plug pi in there you simply get degrees with radians, which are calculated with pi(not sure about the math there, but that's how it is) so cos(pi) + i*(sin(pi))= -1. put it in a calculator and u will get -1. in fact, if you simply put cos(pi) + sin(pi) you will also get -1.
@@marxk4rl well, that's the beauty of it, if you plus pi into sine or cosine you get an integer, and you can cancel out the imaginary number too. for example i*i=-1. now if you studied calculus you'd know you can represent sine and cosine by series, and this is exactly what you get with e^(i*pi) you get the representation of cos(pi) + isin(pi) so the math and it will give u the same result as i*i.
IDK if it's the beauty of mathematics or the beauty of Toby's demonstration or her own beauty that's making me go crazy.Probably a mixture of all three! Gonna come back to these vids for sure
Thanks Toby...I was surrounded by university level science oriented people growing up, got my degree in math, but somehow never ran across this. Very neat interrelation of four special numbers, e=mc² like!
This is the first time I understand, without over romanticizing in my head, the real beauty of an equation. Pure beautiful mathematical knowledge. You are really amazing. Thank you, my brain is really happy right now!.
I love your passion for the science. You are my Idol scientific. I'm studying chemistry, but all into science is beautiful. Greetings from Mexico. Tibees ✨🌟 😊
The proof is elegant and simple once the series expansion is taken for granted. Please do videos for series expansion proofs. Thanks so much. Never understood it my college days, its really simple , elegant and clear explanation.
Toby, thanks for this lovely video. My heart skipped a beat after calmly following your explanation and then suddenly recognizing the pattern in the series for cos(x) and sin(x) in exp ix 😉
I have watched this a few times and really like the way toby presents this. I think a quite hard headed approach is required for mathematical content, and Toby contrasts this with her smiling personality.
I loved Bob Ross so much. He was my first and best art teacher. I think of him and talk about with my wife often. She now likes to watch the old Bob Ross videos too. This is still all totally over my head though sadly. But for the first time ever, I feel like I could learn maths from someone. You seem right and the Bob Ross link is an ethereal helper. I'm going to look through your videos and see if there's a good entry point..... Thank you for doing these. I love that someone out there thinks a bit like I do! I had to school myself alone for reasons too detailed to go into but I still do the same thing. I take my ignorance and use it as a measuring tool to find the correct shape and size of a subject....
I had a Math teacher in College that scared me and my classmates during one year in College. When i was playing during break with my friends, when the ring bell to stop the break we we're all scared in front of our classroom door. Everybody was happy to go in class, except us. And i hated math because of her. Gladly i did economy and sociology with help of other teachers and now i'm a teacher too in economy and sociology but it was difficult (because of maths and using statistics). What i'm saying is... Your video prove Math can be teaching in a soft, calm and cheesy atmosphere. I think we could learn to do Maths during spring or summer , outside, around natural environment like you did. It's amazing, congrats about your video.
This one is solution of euler's form. Cos(a)+i Sin(a) =e^ia i=iota, put a=π.. And get the most famous result e^iπ=-1... Actually we use to study it in complex no. Of high school(11th stndrd)
This is without a doubt the best channel on RUclips. I could listen to you explain math and physics all day. It reinforces all the things I learned while pursuing my engineering degree and it actually is so much fun lol
This video is proof that even mathematics can be used to heal stress, not just music. By the way, when you said don't be scared by the equations on the board, i was greatly, " relieved " 😊😊😂😂😂
This stuff made so much sense as an extension of elementary Algebra. Vectors were trivial after complex equations and quantum physics started to make sense after the Complex Analysis math course.
I don't think people get the intuition behind this as well; any real number to the power of i represents a rotation on the unit circle on the argand plane, and when that real base is e, the rotation on the argand plane gives exactly one radian anti-clockwise from 1+0i. Multiplying by pi would therefore mean 1 rad * pi = 180 degrees thus it would land you at a full 180 degree rotation from 1+0i to -1+0i. Then you add 1, meaning a translation of one unit to the right which gives 0+0i. Thus e^(ipi) + 1 = 0
That’s quite nice. I think it was GH Hardy who said that this equations should be obvious to any mathematician. Your intuitive explanation is the closest I’ve got to understanding that statement. In case others were wondering, the Argand plane is the complex plane (x = real, y = imaginary). Also, 180 degrees = pi radians.
For the first time in this life I could see that e^(i*pi) = -1 has three distinct constants all related by this equation. Thank you for making a fantastic video. I really like the scenic backdrop. It uplifts the mood immediately. I saw a Bob Ross video as well. That was also a treat.
Here's the perfect equation : (beauty + intelligence = Tibees) I hear so much of your interest in psychology that you mentioned in a different video coming through in the way you explain things. I love that.🙌
That’s the charm of math.When I was study at high school, and came across the e,and wondering why this number can behave so special in differential.And in college, I finally got the answer. I wish I could work out this kind of problem as my daily job someday.
This video is inspired by a Bob Ross tutorial: ruclips.net/video/lLWEXRAnQd0/видео.html
