Today (August 13, 1814) is the birthday of Anders Jonas Angstrom (Å), who studied the spectroscopy of polar light.

Today (August 13, 1814) is the birthday of Anders Jonas Angstrom (Å), who studied the spectroscopy of polar light.

Anders Jonas Ångström was born on August 13, 1814, in Medellbot, to Johann Angstrm. Arnosand attended school. He went to Uppsala in 1833 and studied at Uppsala University, graduating in physics in 1839. In 1842 he went to Stockholm to train in practical astronomy. The following year he became in charge of the Uppsala Observatory. Out of curiosity about the Earth's magnetic field, Sweden measured and recorded differences in the magnetic field of many parts of the country. He was given responsibility for the work by the Isudacolm Academy of Sciences. From 1851 to 1853 the Swedish brigade took magnetic measurements around the world in a cell called Eugene, which he could not complete until shortly before his death.

Angstrom was succeeded by Adolf Ferdinand Schwanberg in 1858 when Uppsala sat on a physics couch. His primary studies were in heat conduction and radiology. In his 1853 study of optics, Optiska Undersökningar, sent to the Swedish Academy of Sciences by the government, not only stated that there are two types of radiation in an electron beam, but that one emits metal and the other emits transmitting/flowing gas. He also used the oil's synchronization theory to show that the ventilated gas emits the same wavelengths that it does not absorb. This claim was made by Sir Edward's Council in 1872 when he was awarded the Rumford Prize by the State Council. So he was the pioneer of radiology even though he was not seen for many years afterward.

In 1855 he discovered the fact that a heated gas absorbs the same wavelengths at which it emits light at lower temperatures. This was confirmed four years later by Kirchoff's research. In 1861, Bronhopper studied the lines and confirmed the presence of hydrogen in the sun. Angstrom made his measurements at 10 ⁻¹⁰ m. Later, a unit of 10 ⁻¹⁰ m = 1 Å was created to honor him. Angstrom has also done his research on the spectroscopy of polar light.

After 1861, Angstrom began to focus on solar radiation. He combined photography and radiology to study the solar system in 1862 and discovered that water, along with other elements, is present in the solar atmosphere. In 1868 he published a detailed study of the largest radiation, measuring 1000 radiations of natural solar radiation. His measurement, although erroneous due to the lack of a scale for a fraction of 7000 or 8000, was accurate in terms of wavelength. In 1867 he first studied the Northern Hemisphere. In it, he measured the glorious fort located in the yellowish region. He erroneously assumes that one part of the 7000 or 8000 shares of his so-called Iridzburg name is faulty, but that the same code is located in the twilight range.

Angstrom was selected as a member of several laboratories. He became a member of the Swedish Government Academy of Sciences in 1850, the University of London in 1870, and the French Institute in 1873. His son, Knut Angsudram (1857–1910), was also a physicist. The pioneer of radiology, Anders Jonas Angstrom, passed away on June 24, 1874, at the age of 59 in Uppsala. The wavelength and atomic distance measured in the concentrated matter are given by his name as the Angstrom unit (1 Å = 10−10m). One of the Moon's craters is named Angsudram Volcano. In his memory, the main building of Uppsala University is named Angstrom Laboratory.
