The Civilised Glass

Sign up for the Grand Illusions newsletter, at http://conta.cc/3dplns1 _______________________________________________________________________ This elegant wine glass contains a secret mechanism that is supposedly at least 2,500 years old. A simple piece of physics, although maybe slightly deeper in philosophical terms. The glass looks normal, except that there is a slender central column inside the glass. If you pour wine into the glass, you can drink it in the normal way. However you have to be careful when filling the glass. If you fill the glass beyond a certain level, the glass will empty - every drop will drain out from a hole in the bottom, and you won't get a drink at all. The idea is attributed to the Greek philosopher Pythagoras, who lived on the Island of Samos 2,500 years ago. As he wrote nothing himself, we only know about Pythagoras from the writings of other people, especially Plato. However as well as his fame as a mathematician, he is also celebrated for his philosophy and his way of life. The Civilised Glass illustrates a point that we should not ask for more than our share in life. See http://www.grand-illusions.com/acatal...
