  2. Femtosecond - Wikipedia

    en.wikipedia.org/wiki/Femtosecond

    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.

    The entire film is set inside a loft featuring four mullioned windows and minimal furnishings—a desk, a yellow chair, and a radiator against the far wall, with several photographs hanging above the chair. The film begins with a wide shot of the loft, and the image gradually zooms in on the wall as the story progresses.

    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 ...

  5. Femtochemistry - Wikipedia

    en.wikipedia.org/wiki/Femtochemistry

    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).

  6. List of films featuring miniature people - Wikipedia

    en.wikipedia.org/wiki/List_of_films_featuring...

    The earliest film to have a shrunken person was a 1901 short The Dwarf and the Giant by Georges Méliès in which a character was split into two, with one growing in size and the other shrinking. Before digital effects became commonplace, composite screens were used to create the illusion of miniature people.

  7. List of longest films - Wikipedia

    en.wikipedia.org/wiki/List_of_longest_films

    While most cinematic films have a broad theatrical release in multiple locations through normal distribution channels, some of the longest films are experimental in nature or created for art gallery installations, having never been simultaneously released to multiple screens or intended for mainstream audiences.

  8. Ultrashort pulse - Wikipedia

    en.wikipedia.org/wiki/Ultrashort_pulse

    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.

    First known film is the first film (not including tests) made with the format and intended for release. Negative gauge is the film gauge (width) used for the original camera negative. Negative aspect ratio is the image ratio determined by the ratio of the gate dimensions multiplied by the anamorphic power of the camera lenses (1× in the case ...
