jan 1, 585 BC - Buddha has proposed the existence of kalapas. Kalalapas are invisible particles which may have been the first time someone ever mentioned something like this. Each particle vibrates trillions of times in a blink of an eye. This was the start of a new important part of science that we still use today.
