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:
“pulling off the fat diamond engagement ring,
pulling off the elopement wedding ring,
and holding them, clicking them
in thumb and forefinger,
the indent of twenty-five years,
like a tiny rip leaving its mark....”
—Anne Sexton (1928–1974)
“I had but three chairs in my house; one for solitude, two for friendship; three for society. When visitors came in larger and unexpected numbers there was but the third chair for them all, but they generally economized the room by standing up.”
—Henry David Thoreau (1817–1862)
“Everything in science depends on what one calls an aperçu, on becoming aware of what is at the bottom of the phenomena. Such becoming aware is infinitely fertile.”
—Johann Wolfgang Von Goethe (1749–1832)
