Ok, I haven't even finished watching the video yet (2 minutes remaining) but I just had to pause for a moment and say this: *The animations are fantastic!* They are extremely helpful in demonstrating what Tadashi is saying and really show how complexly you can look at the movement of the spinning tube. Thank you!

There is definitely something invovled in "preferred frequency" because of the camera sampling rate (could be 30 Hz, maybe 60 Hz, etc., in other words, one of the standard video frame rates), so what we see on video is going to be somewhat different than what an eyeball would see. So when I see the tube with the 4:1 ratio, I don't stably see 4 of the color, because it's kind of beating against the camera's sampling rate.

An interesting note on the "floor-ceiling" symmetry mentioned - you can sort of see that effect if you look really closely in the original tests, from certain angles (e.g. around 0:23) you can see a little bit of the inside of the tube, and can indeed see the "wrong" color there intermediate between the "right" color bands from the part of the stripe on the inside of the tube...

I love Tokieda Sensei!!! He brings a whole new view to Numberphile by combining a little bit of physics in with math theories in these real-world applications, or I guess I should say toys. Each video with him makes this whole channel seem much more substantial and applicable in the real world than most math theories are on their own. Not to say the other professors aren't superb on their own, I'm just saying that Tokieda is very unique when it comes to teaching style and it's his and Cliff's videos that I get the most excited for on this channel.

I catch myself re-watching Tadashi's videos so much. What a profound understanding that we are literally surrounded by puzzles and mystery at all times. Simple interactions that are easily glossed over become beautiful complex systems under observant eyes that blossom out from curiosity and creative thinking. My world becomes even more complex and nuanced every day I become more aware of what that world really is. Awareness has brought a lot of pain to my life, being able to see the deeper fabric of systems that are interconnected means seeing all the ugly that is obfuscated by the veil of illusion. but it's has also brought back child like play and curiosity and has solidified a desire to keep engaging with my surroundings and grow the beautiful and joyful parts of my existence on planet earth. I might just be a melodramatic fan boy... So forgive me! Regardless! Thank you for sharing your knowledge with us all, I don't think many people realize just how special it is that there are people out there who want to share the wisdom/skills they have acquired in life without making people prove they are worthy of possessing the knowledge. I hope this part of the internet never changes!
