I read some paragraphs from Michio Kaku's Hyperspace about Abdus Salam's illustration of symmetry breaking using a banquet table. Left-right symmetry breaks when one diner picks a glass on the right or left. What if two diners simultaneously picks up a glass. One diner picks up a glass to his right while the other picks up a glass to her left. In the end, surely, someone will have no glass to drink from. Right?
