"nature always does the calculations perfectly" well, considering math was invented to describe nature, that is inherently true

[@vsm1456]

Not really true. 1) Maths evolved beyond its initial goal of describing nature and is now a pure abstract thing of its own. The disciplines that describe nature are now called natural science. Its relation with maths is that it uses some parts of maths as tools, but maths itself is not a part of natural science (just like a technician that comes to your house to fix things is not a part of your house or your family - you use their expertise but you don't own them). 2) Most mathematical objects can't exist in real life in a "perfect" way, because natural objects are bound by our universe's limitations while maths objects can be whatever we want. Nature doesn't calculate anything, it just exists by its own rules and it doesn't match maths 1:1. For example, the soap film has width and local imperfections because of air currents, shock waves going across the film, etc. while mathematical minimal surface has none of those, it's truly perfect.

Besides, the minimum surface is a great analogy to a lot of things in life, such as craftsmanship, career development etc. Gradual refinement (doing things which are natural consequences of the things you did so far) produces a minimized, optimized result (for example a perfected skill). But if you ignore the gradual process, and design the end result (for example choose a mentor, or choose to get a university degree), you can skip ahead to a state that you would never achieve otherwise, just like the normal egg surface, which has smaller area than the minimal surface.

After watching this I'm pretty sure my brain has now gone to minimal surface. This was an interesting topic, thank you!!!

[@monkeybusiness673]

That "almost looks like a hypercube; forming a square in the middle" cube was probably the coolest thing I saw in a very long time. Cheers, Mate!

[@AntithesisDCLXVI]

When he pulled the cube from the bucket and it had a square floating in its center... 🤯

[@gavinjenkins899]

He just didn't make the cube cubey enough, it was longer in one direction. A cube should come down to a point not a square.

Thanks for driving my curiosity! I wonder what would happen if we took a minimal surface egg or other object to space and set a drop of water on it. Assuming no gravity and the force of the droplet coming out of a dropper, do you think this would allow the water to follow the minimal line until eventually the droplet runs out of energy, and basically comes to a standstill no matter it's orientation?

[@wmose3694]

that part where you actually dipped any of the shapes from the egg to show how it would form as a bubble that part was great

[@Sedona_FD3S]

I finally understood when I said “minimal surfaces on the same plane” out loud.

This guy is so incredibly cool. Great video and, as always, very interesting and informative. I hope you teach 4th grade science because people like you can change lives with your knowledge and enthusiasm.

[@demonindenim]

4th grade science is pretty specific, why 4th in particular

[@Lillmackish]

This video is super cool and all, but what I find to be most impressive is the fact he literally walked around the earth, just to prove a point.

[@lastchance8142]

Brilliant! Outstanding, insightful presentation! Thank you for all your hard work on this one.

[@evang6503]

I have seen Greg do the finger Wiggle many times on your videos but I had no idea quite the speed until you showed me on the Chrono it’s amazing!

[@pablorepetto7804]

"Minimal surfaces" is such a misleading name. It implies that surface is being minimized, but what's being minimized is potential energy. "Minimal energy surfaces" or "minimal potential surfaces" is much better. "Saddle point surfaces" would probably also work?

[@MammaOVlogs]

wow way interesting, good job explaining

[@globalwarmingwarning6556]

My mind blown after seeing the square at the end, man! That was freaking cool !

[@bug5654]

TFW you've been in 3d rendering and math long enough to correctly intuit the cubes minimal surface area.

[@arenzetlian1480]

0:29 You could have just said "reggular" Regular egg is a tad redundant, wouldn't you agree?

[@hotfightinghistory9224]

Best quote of the week for me! "That's the great thing about nature, it always does the calculations exactly perfect!" :):):):)

[@richardmondio7216]

His wife has been trying to tell him about "Black Hole" and "minimal surface" for years. He just won't listen. He still hasn't figured out the shortest path to the bedroom.

[@omnacky]

I don't get it

[@alex-fy8sy]

Lmao

[@allytie736]

Lol yes

[@frh_astroboy8215]

That is he always walk the entire Earth to get to bed

[@blueskyla7978]

I wanted to see you dip the eggs in soap! Ugh. Oh well. I figure though there’s not much to see as the soap should cling to the total surface with no soap creating its own surface. I was fascinated the square nearly looked like a tesseract. That was sweet.

[@meanmugging]

I'd have to watch this 10 times to understand minimal surfaces but my mind was blown with the string on the bubble and the cube bubbles.

[@prathmeshkulkarni2079]

You make physics interesting😍😍

[@aliciashaz6577]

Minimal surfaces are in math.

[@crazy4hitman755]

7:37 plot twist: he actually walked around the entire earth

[@cesarcampuzanomartinez8182]

😴

[@Fireheart318]

My jaw dropped when the cube did that tesseract thing!

[@RaivoltG]

Maybe as a part 2 to this video you could make crazy 3D shapes and dip them in soap. The 3D box was awesome! If you decide to make a part 2, can you explain why the shapes come out like they do?! Very cool video! You never disappoint, every video is super interesting, you've really done a great job creating your channel! I can't wait for your next video!
