Small Number - Tiny Numbers in Science

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 a house is tottering to its fall,
    The strain lies heaviest on the weakest part,
    One tiny crack throughout the structure spreads,
    And its own weight soon brings it toppling down.
    Ovid (Publius Ovidius Naso)

    All ye poets of the age,
    All ye witlings of the stage,
    Learn your jingles to reform,
    Crop your numbers to conform.
    Let your little verses flow
    Gently, sweetly, row by row;
    Let the verse the subject fit,
    Little subject, little wit.
    Namby-Pamby is your guide,
    Albion’s joy, Hibernia’s pride.
    Henry Carey (1693?–1743)

    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)
