I love Matt Parker to death, but he isn't a proper mathematician. He is a clever math hobbyist, a hilarious and effective educator, but not a proper mathematician. And that's why he downplays it. He knows it, and knows that proper mathematicians would see right through him, and would call him out on it, if he pretended to be, so he prefers to set realistic expectations.

This man is an absolutely brilliant communicator. He’s funny, he has insight, he knows what matters, and he can put it all together into a coherent and fluid presentation. That it what I want to learn from him. How to be this good at presenting on a topic.

I tend to use opacity to represent the fourth dimension when i try to manipulate 4D objects in my mind. I just keep in mind that if two pieces have different opacities then they don't touch. I like to define 0 in the opacity dimension as 50% opacity so i have room to go in both directions Then for rotations it helps to realize what a rotation is. So for 2D you pick a point (a 0 dimensional shape) and everything keeps the same shape and every other point stays the same distance from that point. In 3D you take an infinite line (a 1D shape) and everything keeps the same shape and distance from the line. So in 4D you take a plane (a 2D shape) and do the same thing. I recommend limiting what planes you can use just to keep things simple. So the 3D equivalent is just rotating around the point at (0,0). In 3D it's the lines corresponding to (X, 0, 0), (0, Y, 0), and (0, 0, Z). In 4D each plane is defined by two coordinates. If one of those coordinates is opacity then it just looks like one of the lines you use in 3D and the rotations look the same, that accounts for 3 of the planes ([o, x, 0, 0], [o, 0, y, 0], and [o, 0, 0, z]). The other three are the planes where you've picked 2 of the normal 3 dimensions (x, y, or z). You've got four dimensions and you're picking 2 of them, that's why there are 6 rotations in 4D, it's 4 choose 2 (look up the choose function to learn more or to easily calculate it for higher dimensions). To rotate around the latter 3 options the points either stay in the same spot (if they're already touching the plane, like how the earth's pole's don't move when the earth rotates), they move farther away in 3D while their opacity matches the plane more or move closer to the plane while their opacity starts to match it less. Things on one side of the plane should become more opaque if they move closer and things on the other side should become more transparent as they move closer, that way opposite sides of the object maintain the same 4D distance apart even if they are in the same spot in the 3 normal dimensions I recommend starting by rotating 3D objects in 4D. Like try a 3D sphere that starts centered on (0, 0, 0, 0). All possible to be done just in your mind

Matt would like you to think the soapy mixture found the minimal surface with a small cube bubble in the large one. I think he was using a square straw.

I was just going to relax for a few minutes and Matt’s videos are always great fun. 50 minutes later I experience the true relativity of time. Matt is so cool. And what a wonderful way to round off the Abel Lecture.

From 39:00 in, the number of possible rotations in d dimensional Euclidean space over the reals *R* where d > 1: (d choose (d - 2)) = (d choose 2) = d(d - 1)/2. In other words the triangular numbers 1, 3, 6, 10, 15 and so on. So Matt was right when he said 10 for d = 5.

I love that he starts his Abel lecture with Numberphile's video on a non-standard summation method. Very fitting.

I mean, gotta love the talks by Matt. It‘s always a pleasure to see a subject, which I understood half-way so far and having it explained with that amount of humorous elements.

Holllllly shiiiit. The upmost respect for dealing with a heckler live on stage at the very beginning - that was awesome

For the 3D/4D cube, try reading a short story by Robert Heinlein. The story is called "And He Built A Crooked House". Essentially, he built a house which was an unfolded tesseract, i.e. it was four cubes stacked vertically, with extra cubes glued on each of the four sides on the first floor. This is EXACTLY like the picture at 35:45 or thereabouts. In the story, he built the house in California, and California has earthquakes, so... one of these earthquakes caused the house to fold itself into a real tesseract. Mayhem ensued.

Watched it with my six year old, she loved the bubbles (obviously the bubble isn't going to be a cube with a square bubble blower!) then was delighted by the actual cube bubble payoff later on.

okay with the bit about rotating a cube then a hypercube, i squinted a bit and i suddenly was *seeing* rotation rather than self intersection. my brain is in the process of evaporating as we speak

adding a small amount of glycerin to your soapy water will help with the bubbles, makes them stronger

@MattParker, some extension to 1-twist Möbius strip cutting: * Cut strip in half as you did. Then cut it *again* in half. * Cut strip in 1/3 of its width, not 1/2.

I am the kind of person to point out “hey that is a three twist möbius loop” to my friends and family. Thank you for telling me this.

That four towns problem just used hexagons. Since hexagons come from circles it makes me think the problem could be solved with circles. Minimal surface of cube doesn't work out as obviously cleanly though. It's did make me want to see the minimal three dimensional surface of a tesseract though.

Well, it took you a while, algorithm.

I tried the two conjoined Moebius strips with the same handedness, and I got two loops: one sorta boring one that looked like a boat hull, but one more interesting one that looked like two half-heart shapes with a full twist in them.

Wonderful talk - deserved a better audience.

Your surface tension was too low in the 4D bubble box demo. Your bubble mix probably had too much soap or not enough water. The soap to water ratio in other words. Any instability in the system will show as a square. Higher surface tension would give the singularity more stability.

You do _NOT_ get "-1/12" if you sum all integers to infinity. The correct answer to that kind of series is that it _diverges_ - it approaches infinity. I am assuming that the "-1/12" thing must haver something to do with Ramanujan Series - it is certainly not an _ordinary_ series.

On the other hand, it would be such a pain that will be even less likely to happen.
