"A group of three researchers earned the 2023 Nobel Prize in physics for work that has revolutionized how scientists study the electron – by illuminating molecules with attosecond-long flashes of light .... Atto is the scientific notation prefix that represents 10-18, which is a decimal point followed by 17 zeroes and a 1. So a flash of light lasting an attosecond, or 0.000000000000000001 of a second, is an extremely short pulse of light. In fact, there are approximately as many attoseconds in one second as there are seconds in the age of the universe". More at The Conversation ➜
