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:
“When that I was and a little tiny boy,
With hey, ho, the wind and the rain,
A foolish thing was but a toy,
For the rain it raineth every day.
But when I came to man’s estate
With hey, ho, the wind and the rain,
‘Gainst knaves and thieves men shut their gate,
For the rain it raineth every day.
But when I came, alas! to wive,
With hey, ho, the wind and the rain,
By swaggering could I never thrive,
For the rain it raineth every day.”
—William Shakespeare (1564–1616)
“One murder makes a villain, millions a hero. Numbers sanctify, my good fellow.”
—Charlie Chaplin (1889–1977)
““You are bothered, I suppose, by the idea that you can’t possibly believe in miracles and mysteries, and therefore can’t make a good wife for Hazard. You might just as well make yourself unhappy by doubting whether you would make a good wife to me because you can’t believe the first axiom in Euclid. There is no science which does not begin by requiring you to believe the incredible.””
—Henry Brooks Adams (1838–1918)
