Because the next higher SI unit is 1000 times larger, times of 10 −14 and 10 −13 seconds are typically expressed as tens or hundreds of femtoseconds. Typical time steps for molecular dynamics simulations are on the order of 1 fs. [4] The periods of the waves of visible light have a duration of about 2 femtoseconds.
10 nanoseconds, also a casual term for a short period of time. microsecond: 10 −6 s: One millionth of a second. Symbol is μs millisecond: 10 −3 s: One thousandth of a second. Shortest time unit used on stopwatches. jiffy (electronics) ~ 10 −3 s: Used to measure the time between alternating power cycles. Also a casual term for a short ...
Femtochemistry is the area of physical chemistry that studies chemical reactions on extremely short timescales (approximately 10 −15 seconds or one femtosecond, hence the name) in order to study the very act of atoms within molecules (reactants) rearranging themselves to form new molecules (products).
A positively chirped ultrashort pulse of light in the time domain. There is no standard definition of ultrashort pulse. Usually the attribute 'ultrashort' applies to pulses with a duration of a few tens of femtoseconds, but in a larger sense any pulse which lasts less than a few picoseconds can be considered ultrashort.
57 Seconds follows Franklin Fox (Josh Hutcherson), a tech blogger with a deep interest in the potential of AI for healthcare. His life takes a dramatic turn when, during an interview with visionary CEO Anton Burrell (Morgan Freeman), he inadvertently thwarts an attack, after which he discovers a mysterious ring belonging to Burrell that allows him to travel 57 seconds back in time.
