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:
“We cannot cheat on DNA. We cannot get round photosynthesis. We cannot say I am not going to give a damn about phytoplankton. All these tiny mechanisms provide the preconditions of our planetary life. To say we do not care is to say in the most literal sense that “we choose death.””
—Barbara Ward (1914–1981)
“I’m not even thinking straight any more. Numbers buzz in my head like wasps.”
—Kurt Neumann (1906–1958)
“By an application of the theory of relativity to the taste of readers, to-day in Germany I am called a German man of science, and in England I am represented as a Swiss Jew. If I come to be regarded as a bête noire the descriptions will be reversed, and I shall become a Swiss Jew for the Germans and a German man of science for the English!”
—Albert Einstein (1879–1955)
