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.

Quite entertaining

Bongriz on

Found this enlightening and well presented.

Great but ....

Great app introducing my son to 4D, but: 1) Shouldn't it be an intersection and not a shadow to visualize it? 2) It would make it easier to see the 3D effect if the distance between the centers of the two images were closer to the distance between a normal set of eyes and not half the width of the ipad screen some are better at crossed eyes stereo grams so maybe add that option?

Fantastisk

Unravelling the mystery wrapped within a conundrum inside an enigma! Mind warping app.

En virkelig intuitiv måde at forklare dimensioner ud over dem vi lever i :)
