" 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."
"... there are approximately as many attoseconds in one second as there are seconds in the age of the universe."

What is an attosecond — and why did this year's Nobel Prize in physics depend upon them?
A billion billion attoseconds just passed while you read this. Why is such a tiny timeframe crucial to this year's Nobel physics prize winners?
