There are 605 quintillion—605,000,000,000,000,000,000—femtoseconds in a week. Thanks for joining us for Femtosecond Week!
One attosecond is time it takes for light to travel the length of two hydrogen atoms.
Vibrations of atoms in iodine molecules occur in 300 femtoseconds. Learn more ultrafast materials science tomorrow during Femtosecond Week.
We can watch certain chemical reactions occur in femtosecond frames:
A femtosecond is to 1 second as 1 second is to 31.7 million years.
To date, the shortest X-ray laser pulses delivered by LCLS last 5 femtoseconds, about the same time a molecule takes to lose an electron.
As fast as the blink of an eye? That’s still about 350,000,000,000,000 femtoseconds.
“Femto” means a factor of 10-15. It comes from the Danish word for fifteen, “femten”.
A femtosecond is 1 quadrillionth of a second.
