2000 BC: Multiplication tables in a base-60, rather than base-10 (decimal), system from Babylon. [7] 2000 BC: Primitive positional notation for numerals is seen in the Babylonian cuneiform numerals. [8] However, the lack of clarity around the notion of zero made their system highly ambiguous (e.g. 13 200 would be written the same as 132). [9]
For their work the three received the Nobel Prize in Physics in 2004. 1974: The J/ψ meson was independently discovered by a group at the Stanford Linear Accelerator Center, headed by Burton Richter, and by a group at Brookhaven National Laboratory, headed by Samuel Ting of MIT. Both announced their discoveries on 11 November 1974.
