Visualizing the tesseract

Have you ever had problem visualizing the fourth dimension? I have found this app - The Fourth Dimensional App - which helps you visualize the tesseract. (A tesseract is the four dimensional analog of a cube.)

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.

This amazing app is free for a limited time. Download it now! Visit

Note: It is only available for iOS devices.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

If you search this app on Google, it shows $2.99 in the search result, but if you open it in the App Store or on the iTunes website, you will see it is free (as of 5pm IST 28 Feb 2015).
