Kayser was born at Bingen am Rhein.Kayser's early work was concerned with the characteristics of acoustic waves. [3] He discovered the occurrence of helium in the Earth's atmosphere in 1868 during a solar eclipse when he detected a new spectral line in the solar spectrum.
Two of the base SI units and 17 of the derived units are named after scientists. [2] 28 non-SI units are named after scientists. By this convention, their names are immortalised. As a rule, the SI units are written in lowercase letters, but symbols of units derived from the name of a person begin with a capital letter.
This is a list of scientific units named after people.For other lists of eponyms (names derived from people) see eponym.By convention, the name of the unit is properly written starting with a lowercase letter (except where any word would be capitalized), but the first letter of its symbol is a capital letter if it is derived from a proper name.
One of the earliest examples of using sound to represent data is the dosimeter, or Geiger counter. This instrument was designed in 1928 to indicate the amount of radioactivity in a given place ...
List of scientists whose names are used as units; List of people whose names are used in chemical element names; List of scientists whose names are used in physical constants; List of soil scientists; List of spectroscopists; List of statisticians; List of systems scientists; List of taxonomic authorities by name; List of undersea explorers
Other acoustic scientists advance understanding of how sound is affected as it moves through environments, e.g. underwater acoustics, architectural acoustics or structural acoustics. Other areas of work are listed under subdisciplines below. Acoustic scientists work in government, university and private industry laboratories.
Heinrich Rudolf Hertz (/ h ɜːr t s /, HURTS; German: [ˈhaɪnʁɪç hɛʁts]; [1] [2] 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism.
Vladimir Gavreau, born Vladimir Gavronsky (1904 – 1967), [1] was a French scientist making experiments on the biological effects of infrasound. Gavreau was born in Moscow . His interest in infrasonic waves first came about in his lab during the 1960s, when he and his lab assistants experienced pain in the ear drums and shaking lab equipment ...
