The Amazing Work of Kokichi Sugihara

Can a ball roll uphill against gravity?  How can the reflection of a circle in a mirror appear as a rectangle?  Is it possible that an arrow, when rotated 180 degrees, continues to point in its original direction?  Join Kokichi Sugihara, Meiji University Distinguished Professor Emeritus, at the National Museum of Mathematics as he shares one incredibly impossible object after another.  Prepare to be amazed as Dr. Sugihara demonstrates how his clever illusions fool the brain and how math underlies the engineering of each paradoxical illusion.
