A Visual Proof to Behold!
Visual proofs are great, especially when they are of the type "proof without words." They exhibit something so special about mathematics, separating it from all other disciplines.
Enjoy this visual proof, which was suggested by frequent contributor M.J. (Bellingham): Two Cubes Proof
The website is the work of Hyrodium (Osaka, Japan), a 20-year old student in OPUCT. Nice job!
I encourage you to browse his website (e.g. by using the link "Home"), as it will bring you to multiple other visual proofs and experiences, again all demonstrating the special nature of mathematical thinking.
