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

Over 250,000 people have blown their minds with this app.

I just HAD to review this.

I NEVER write reviews for apps. But this one is amazing. I was hesitant to spend the money on it but I am so glad I did.
I truly feel like I have a better understanding of the fourth dimension because of this silly little app. The app writer is a genius. Thank you sir for this. Now we need one for the fifth dimension and beyond... 😀

Worth the purchase. Allows insight.

Thanks for producing this app. I would like to see the remainder of the Platonic solids as shapes that we (the user) could interact with. I believe this would provide a complete experience. Thanks again.

Now I get it!

This app is excellent. It really teaches and explains clearly and visually so you understand. The developer of this app has a gift for teaching.
From a spiritual perspective, you can see spiritual vs natural easily using this app. Great job!
