The Most Remarkable Theorem Part I (Theorema Egregium)

[@sackixfilms8950]

If anyone is wondering the footage from the start of the video is from a movie called “Die Vermessung der Welt”, which is about Gauss and Alexander von Humboldt

[@lanimulrepus]

Excellent start to a subject that caused many sleepless nights for me 60 years ago... Look forward to the follow-up editions..

[@vtrandal]

I absolutely love this video: content, backdrop, music, etc all of it. Thank you!

[@tonygeorgiou6939]

I love the way you present . Please keep doing more

[@talalabdou]

Very nicely presented. However, I have to mention that the background music was very loud and distracting which diminished the value of the very good work

[@ffggddss]

Nice intro to the subject of curvature. As you were going along, I thought there would be some discussion of so-called Gaussian, or surface curvature, which for a 2-D manifold embedded in Euclidean 3-space, is specified by a single parameter, but for higher-D manifolds is a tensor (of rank 2? or 4? The Riemann curvature tensor? I'm a little rusty on my differential geometry). But your presentation of linear curvature was spot-on. Anyway, I was hoping the title was referring to the Gauss-Bonet Theorem, a truly remarkable relation between linear and surface curvature! Fred

[@shruggzdastr8-facedclown]

Just as a curve can be defined (whether geometrically, trigonometrically, via calculus, or any other higher math) in terms of a line, a line can in turn be defined in terms of a curve, describing it as the perimeter (or segment of that perimeter) of a circle whose radius is of infinite length

Michael Penn also has some good videos on vector geometry and topology wherein he goes into the actual nuts and bolts math, itself

[@KaliFissure]

I think you'll find that if you apply a similar flow to this form, Shirley's Surface, it will both describe the flow of the universe but also demonstrate a topology for renormalization Why it requires 4pi to complete Surface Surface(cos(u/2)cos(v/2),cos(u/2)sin(v/2), sin(u)/2),u,0,2pi,v,0,4pi

1:00 I figured that out as a kid, too, in the context of playing Yahtze. The upper-section bonus needs a certain number of each count, on average. I don't recall the exact chain of reasoning, but I figured out the pattern when trying to rapidly ascess the progress and make decisions on how to fill in the upper section. 1..6 is not as labor-saving as 1.100, but once I realized this, 1..100 was the next thing I did.

[@brettmoore3194]

@@leif1075 well most of the previous map makers were under the impression the globe is a sphere. Indoctrination is one hell of a drug. Previous ancient maps showed correct land and sea but soon as the cult of Pythagorean confused people. Its very interesting old myths and legends get verified as we get more advanced they can't keep all the little lies going... Could you imagine if all space and military funding went to bettering humanity... This is why the world is the way it is. Some people know the truth and use it as a weapon. Because if you believe in lies you will never be able to come to a concrete solution for problems facing individual and collective lives

Fifty years ago I used the textbook ‘Differential Equations with Applications and Historical Notes’. The historical notes included biographies of relevant mathematicians, and I recall reading there for the first time about Gauss, Euler, LaPlace, Bernoulli etc. Gauss is - arguably - the greatest mathematician of all time. I never liked the story about his adding the first 100 natural numbers. Common sense tells us that this sum is very simple, and there probably isn’t a classroom without at least one student who could not pull off the same trick.

[@nicolasreinaldet732]

Just now you crashed my pride for having done that when I was 10 :(

[@vlix123]

Thats not true. No 10 year old, hwoever mathematically gifted, could’ve pulled that off without seeing a trick like that beofre. Its easy enough to say something is easy once you have seen an elegant and simple solution of it. Common sense would tell you, however, that it is surprisingly difficult to be original and do it without seeing an example first.

[@ericrawson2909]

I did it by adding the numbers in pairs: 100+1=101=99+2.......=51+50. So, fifty lots of 101=5050. I didn't need to introduce a second series of numbers.

[@nicolasreinaldet732]

@@ericrawson2909 I did it in a similar maner, but I used the zero so I had one 50 pairs of 100 and one pareless 50 ( this one got me at first and I took loonger to get it )

[@JojiThomas7431]

But I think the idea is similar, not exactly the same, but similar. Hats off to you for such a nice trick.@@ericrawson2909

Karl Gauss inside doughnut......that was nice

[@CudaWudaShuda365]

This just seems wrong. Imagine if all the internal space of the toroid was filled with really long strings. Would only the strings along the edge wrap around to their end points of would strings in the middle also wrap around to their endpoints. Basically it seems like it should be a sphere or infinite space or a physical barrier along the edge because at the center of the ring on the toroid-let me rephrase this point. If you took a donut with a hole in the middle of it and put in on the table and took a knife and cut it perfectly in half you would see that you now have two circles where the ring crossed through to the other half of the donut. Now in the very center of one of those two circles would space wrap around to itself in a tighter and tigger circle to closer you got to the center of one of the two circles (in the toroidal model of spacetime)? Probably not. What I'm suggesting is that there would be a sorties paradox there to be seen if conceptualize correctly that on one hand you have the edge of the circle which wraps around to itself right? And on the other hand, in the center of the circle you either have just space without any wrapping around onto itself, or a tighter and tighter string that wraps around to its own end getting smaller and smaller the closer you get to the center of the ring of the toroid. It's really hard to explain without being able to point physically at what I'm talking about but it makes more sense that there is a physical wall somewhere out there in the universe or there is just endless space without bounds. Just a thought

While the story might very well be apocryphal it is still attributed to Gauss. 5 seconds of googling should convince you of that.

How did Gauss know that he had to divide by 2?

[@bazsnell3178]

Because he could easily see that he wrote every number down twice, so had to half the result.

[@Sapientiaa]

@@bazsnell3178 That’s my question. How could he see that?

[@Sapientiaa]

@@eratous4477 Again, HOW did he know that he wrote every number down twice. How did it even come to that in the first place. The video doesn’t give details. My question is if Gauss had an intuitive feeling as a child. It clearly appears to have been an intuitive feeling for the kid; that’s insane intuition for a child like Gauss. Obviously 100 values don’t check out for us.

[@Sapientiaa]

@@eratous4477 I understand that you eventually hit 51/50 therefore it caps at 50. The boys intuition about adding these values backwards and then realizing it caps at 50 is extremely impressive for his age.
