The Fourth Dimension

After working through this fascinating (mind boggling) exercise I need to go and lie down. Fabulous (in more ways than 1).

First off, I’ve no idea how long ago I downloaded this app, I’m belatedly having a clear out of old apps on my iPad, and had a look at this one because I had no memory of what it was. I just watched the whole thing for the first time, and am blown away by how much the explanation made sense to me. Not just because it was so clearly and cleverly explained using words and visuals, with exactly the right balance of interaction by me, the user, although all of those things are true. But because I have dyscalculia, and struggle to do even basic maths, and although I loved the ideas in physics at school, (and am still fascinated by theoretical maths and physics*) I didn’t and don’t understand any of it at all. In addition, anything to do with visualising data I find extremely difficult and frustrating. So when I say I’m shocked at how much this made sense to me, I really mean it! I wish you’d been my teacher at school, all those years ago. *my brother is a maths geek so I get to hear about the wacky theories without understanding them. A blessing and a curse. ———————————————————— Do that thing about time being relative to speed next! Or whatever it is. Time travel, I really want to understand the theoretical concepts of time travel. I’ve tried so many times to understand basic concepts of speed, but get completely confused by anything relative. I’m the person who just can’t accept that if you throw a ball into the air when you’re in a moving train the ball stays where it is relative to the train. I’ve read explanations of this so many times and it just makes no sense to me. It’s like watching a magic trick.

This is absolutely brilliant. I’d love to see it with AR enabled too

Thanks

Mind bending stuff lots of effort has been put in to explain something so complex. Love the 3D magic eye bit.

This was sort of trippy in a good way... i couldn’t take my eyes off this app 😅👏👏👏

Incredibly well done explained and demonstrated，thank you

Really awesome app! I wanted to understand the movement of a 4D shape and this app really helps you picture that and also how 4D objects seem to become ‘bigger!’ Would love to know more... about the mirror idea that a 4D person could move objects / make them disappear and reappear! Very interesting and fun to imagine... can you set something up so we can create our own 4D shapes???

Great explanation of a difficult concept, quirky and fun too

I have no words. My mind is blown
