Googol trivia

Ever wonder how Google got its name? It stemmed from the word GOOGOL. Googol is 1 followed by 100 zeros which was coined back in 1938, when it was the largest number. Currently googolplex is the largest number which is 1 followed by 1 googol zeros. Naming large numbers has existed right from Archimedes time. He used a unit called myriad myriad first number (1 followed by 8 zeros), myriad myriad second numbers (1 followed by 16 zeros) and so on to estimate the number of sand grains needed to fill in the known universe. His estimation was One thousand myriad myriad eighth numbers. However today we know that this much sand would fill in Milky Way Galaxybut not the entire universe.
