The Fourth Dimension vs 4D Toys Usage & Stats

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.

4D Toys

"I am not sure that I've ever seen a more compelling 'show-don't-tell' educational tool than 4D Toys." –Ars Technica What if you received a box filled with mysterious toys from a fourth spatial dimension? • Playfully explore and marvel at beautiful shapes powered by a groundbreaking 4D+time physics system. • Poke, throw, roll and watch as they disappear into a dimension you can't see. • Get an intuitive feel for how four-dimensional objects behave: • Become a child of the fourth dimension. In this case the 4D is not time but a 4th dimension of space that works just like the first three dimensions we are familiar with. If you count time these toys are 5D. It turns out that the rules of how objects bounce, slide and roll around can be generalized to higher dimensions, and this unique toy lets you experience what that would look like. Features: • Over 130 beautiful interactive scenes to play with, with more to be added in updates. • Groundbreaking 4D+Time Physics Engine that uses new mathematics created for this project. • Multi-touch & Accelerometer support for rich interactivity. • 2D/3D "Flatland" Interactive 10 Page Book/Explanation that teaches by analogy about a fourth spatial dimension. • Special buttons: Anti-Gravity, Wireframe Projection, 4D Accelerometer and ability to export meshes for 3D printing. Some things to do: • Manage to fit the hypercube into the hyperhole! • Use the 4D shapes as fancy, perfectly symmetric, fair dice that have 5, 8, 16, 24, or even 120 and 600 sides! • Unbind Rings using the fourth dimension! • Make a stack of 4D hypercubes and smash it! • Set up an interesting path for a few 4D dominoes! • Make levers that throw hypercubes into the fourth dimension! • Use multitouch to "squeeze" out objects into the fourth dimension! • Play in a 4D ball pit! • See Tesseracts (i.e. 4D hypercubes) slide down slopes! • etc...!
