Description
The Fourth Dimension is a 30-page interactive book that explains a single mathematical idea in language that anyone can understand. Instead of static images or canned videos, this app employs a unique 3D touch interface that lets you literally grasp the concept of the fourth dimension with your own hands.
“Not only can you blow your own mind over and over again, you can also enjoy watching your friends’ minds being blown in front of you.” — Cult of Mac
“One of the coolest apps I've ever used... The Fourth Dimension is to boring learning apps what Carl Sagan's Cosmos was to staid science documentaries.” — BuzzFeed
“The app is very cool, and it's unlike pretty much anything we've seen in the App Store.” — The Verge
“This is one of my most favorite iOS apps ever.” — George Musser, contributing editor for Scientific American and author of The Complete Idiot's Guide to String Theory
(App Store user reviews follow.)
“Blew my mind. I generally don't use 'learning' apps as they're mostly gimmicks. This one, though, truly made me think. I hope this developer comes out with more outstanding apps such as this one. Bravo!” — Iceitic
“Astounding. That some people care passionately enough about tesseracts to go create a fantastic app for others to understand them is incredible. The app is extremely well designed, wittily written, and executed with love. That alone is worth buying it, besides the fact that I learned what the hell a tesseract was.” — Duncan MacMichael
“Fantastic! This is what someone really smart, and who really knows how to teach well, can do with a tablet. And the authors are funny, too, which is a neat bonus.” — DNY
“Fantastic app. I work at a leading UK university. If only all our material was this well written and presented. Definitely worth buying and then spending a bit of time with over a day or two to get your head around the fourth dimension. Great app!” — JulesFM
“Great job! This app does the best job explaining the 4th dimension. Why learn it in some boring classroom when here you can have an interactive and visual explanation.” — Aco Strklalj

I’m shocked how much this made sense to me!
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.
Fantastic
This is absolutely brilliant. I’d love to see it with AR enabled too
Explains it perfectly
Thanks
Amazing
Mind bending stuff lots of effort has been put in to explain something so complex. Love the 3D magic eye bit.
Wow-
This was sort of trippy in a good way... i couldn’t take my eyes off this app 😅👏👏👏
Absolute genius!
Incredibly well done explained and demonstrated，thank you
Totally mind boggeling
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???
Really cool app
Great explanation of a difficult concept, quirky and fun too
my mind is blown
I have no words. My mind is blown
