At the end of the Video you mention thename of Kevin, who developed the formulas for n-dimensional spheres.
I could not understand his second name or find him amongst the patreon list.
could you, please, give me the second name.
thanks for this and, above all, your Videos!

Why we can not use the gamma function to evaluate the integral

So cool that I just now found this video a week after showing that a random variable counting the number of arrivals as a function of time in a Poisson arrival process must be Poisson distributed using the same style of qualitative conditions -> e argument in the Herschel-Maxwell derivation; a month ago this would all have bewildered me but here I am seeing the same idea used twice!

Theres just one little hole for me: I dont understand why should we use multiplication when we say x and y are independently making up the f function (property 2 at the Wigner explanation). It all works because of that but I dont see why would it be necessary to use multiplication instead of something else like addition.

I can finally feel that the definition of normal distribution is worked out by human beings instead of coming out of thin air, what a great explanation.

We had a joke in our Further Maths class (all two of us😁):
if your answer's got pi in it, it's probably right
if your answer's got pi AND e in it, it's definitely right.

I watched a part of this video already, but paused and after some time I came back to it. And this time, I stopped at the n-dimensional volume formula for the sphere, and man! I just can’t figure out the volume of ball boundary for n=1. Why should it be 2??

прикольно увидеть математически правильное решение.... на физике меняли x^2=X*Y и интергрировали по двум координатам dXdY, в принципе сходится но в истинность слабо верится, хотя таокого в физике хватает

I keep finding in math that learning the history of how an idea was discovered serves to illuminate the idea in general, and makes the "modern" version of that idea so much more satisfying as well as easier to work with. Thank you as always.

This brings back so much memories. I remember the first time seeing this proof in my multidimensional calculus class. I was literally blown away when I connected all the dots. It’s so neat and trivial. I just realised how fun math was back in those days.

I just simply started learning normal distribution but was NOT satisfied with the explanation in the book for Probability density function (PDF) and Cumulative density function, I just started digging and asking why's on how the formula of PDF was deduced. And now I am watching this video. Mathematics is a dark and GORGEOUS !!!
