The Nobel site says 1014: An adult human being has approximately 100 000 billion cells, all originating from a single cell, the fertilized egg cell.]]> 2017-09-26 14:57:28 UTC https://padlet.com/nayar/bignumbers/wish/191289673 Bo nayar https://padlet.com/nayar/bignumbers/wish/191289784 There are 10^80 (100000000000000000000000000000000000000000000000000000000000000000000000000000000) atoms in the universe.

The Plank Unit used to measure time. It is the time it would take a photon travelling at the speed of light to cross a distance equal to the Planck Length. This is the 'quantum of time', the smallest measurement of time that has any meaning, and is approximately equal to 10-43 (0.000000000000000000000000000000000000000000054)seconds.]]> 2017-09-26 15:12:23 UTC https://padlet.com/nayar/bignumbers/wish/191298933 https://padlet.com/nayar/bignumbers/wish/191303125 SINA
An Electron is 1,6 10^-16m

stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). Common Escherichia coli, or E.coli, bacteria are rod-shaped bacteria, 1 micron by 2 microns long. 7.9 x 10^-6 inches
