Tiny Numbers in Science
Even smaller numbers are often found in science, which are so small that they are not easily dealt with using fractions. Scientific notation was created to handle very small and very large numbers.
Examples of small numbers describing everyday real-world objects are:
- size of a bit on a computer hard disk
- feature size of a structure on a microprocessor chip
- wavelength of green light: 5.5 × 10-7 m
- period of a 100 MHz FM radio wave: 1 × 10-8 s
- time taken by light to travel one meter: roughly 3 × 10-9 s
- radius of a hydrogen atom: 2.5 × 10-11 m
- the charge on an electron: roughly 1.6 × 10-19 C (negative)
Other small numbers are found in particle physics and quantum physics:
- size of the atomic nucleus of a lead atom: 7.1 × 10-15 m
- the Planck length: 1.6 × 10-35 m

Famous quotes containing the words tiny, numbers and/or science:
“Sometimes you can tell a large story with a tiny subject.”
—Eliot Porter (1901–1990)
“... there are persons who seem to have overcome obstacles and by character and perseverance to have risen to the top. But we have no record of the numbers of able persons who fall by the wayside, persons who, with enough encouragement and opportunity, might make great contributions.”
—Mary Barnett Gilson (1877–?)
“Until politics are a branch of science we shall do well to regard political and social reforms as experiments rather than short-cuts to the millennium.”
—J.B.S. (John Burdon Sanderson)
