Cost of a Coffee - The Fourth Dimension

This week the Professor and Brian are back and have been asked to peer review ‘The Fourth Dimension‘, an interactive physics lesson available on iOS that will explain 4D to us poor, backwards three-dimensional creatures (and no, I checked, you won’t need to upgrade to a 4D TV). What’s a tesseract? I hear you cry! A tesseract is a four-dimensional shape which is impossible to view properly in our antiquated three-dimensional universe. It’s a bit like a cube on steroids… when viewed with the aid of mind bending psychotropics. However, we can indirectly view a tesseract by unfolding it into three dimensions, or projecting a shadow of the four-dimensional object onto a three-dimensional space. The app even features stereoscopic 3D that will either give you a unique understanding of what the three-dimensional shadow of a tesseract might look like, or a migraine…
