“I've put off watching this video for a little while, but boy am I glad I got around to it. I've only felt this kind of satisfaction watching images warp with mapping images onto fractals with box traps, but this might be better.”

“These videos are gems... I am totally hooked up at the end. This is the first time I'm commenting on any video. Please release the next series. I am looking for it.”

“Very good, it helps me understand how the transform applies to seismic isolator cases... very good.”

“Visualizing the equations increases my interest in learning them so much. I'm a 2nd Year BSc Student, and this semester we have mathematical physics including these equations. Despite it being hard, I'm still falling in love with these equations.”

“I don't think I would ever hear, 'take the natural log of a picture,' and actually make sense! But somehow it does! I'm amazed and bewildered that's a thing! Not only that, but reverse engineering Escher's painting into a straightened out recursive version is crazy! I don't know what to say! It's impressive people can do that.”

“I can't even imagine the work that went into the creation of this video. Incredible job! All your videos are great, but this one surpasses them all.”

“Thanks for providing pieces of work and, in a sense, art, that put into words (and feelings) so beautifully what draws us in to be fascinated with mathematics. I regularly use your videos to explain to other people what the field of mathematics really encompasses and why it is so intriguing, and I believe to have found a new best video to do it with.”

“This may sound stupid, but this is the VERY FIRST TIME in my life that I have been able to visualize higher order dimensions. This video gave me the framework to do that. Until now, I've just had to believe it works, because the book said so because I couldn't visualize in my brain. Using multiple sliders as fields just unlocked something. Thanks!”

“Grant's thinking and what it can inspire in all mathematicians now and in the future is worth a 'Fields Medal'! I am sure that every mathematician who has ever lived would love this!”

“Amazing explanation and wonderful facts, and the most beautiful thing is the way they are deduced, especially the illustrative drawings... Thank you very much.”

“When is the next chapter coming? Also, when is the last part of quantum computing coming? It seems to me like you gave yourself some objectives and didn't think them through, or that you crave new projects when you haven't finished the last one. Anyway, I'll wait to see them both, hoping that you will go back to them.”

“5:09 THIS is why people mistrust Math. You equated utility (as in further usefulness in MATH) with 'reality' (the tangible). Just because it is internally consistent does not make it real.”

“You finally mentioned UNITS at the end. But you can't just ignore units by making r = 1. What about r = 2, or 100K? Even at r = 1, comparing the area of a circle to the volume of a sphere implies that one knows how many square inches there are in a cubic inch.”

“Please, consider not promoting quant trading companies. Sucks talented people to, at best, net zero utility producing companies.”

“This is the single most incomprehensible video I have ever seen on YouTube.”
