Anders Jonas Ångström's 200th Birthday Google Doodle

Google doodle honors Swedish physicist Anders Jonas Ångström for his 200th birthday with a graphic of a man doing a spectroscopy via prism.

Who is Angstrom anyway?

 Anders Jonas Ångström is a Swedisth physicist and one of the founders of spectroscopy. He was born on Aug. 13, 1814 in Sweden. 

Spectroscopy is a study of visible light disperses its wavelength via prism. The Ångström unit (1 Å = 10−10 m) with which the lengths on a scale of the wavelength of light or interatomic spacings in condensed matter is measured are named for him.

According to SiliconRepublic, this unit is used to measure atoms, molecules, microscopic biological structures, the lengths of chemical bonds, the arrangement of atoms in crystals, the dimensions of integrated circuit parts and, of course, the wavelengths of electromagnetic radiation.
