Nazi Germany relied on anthropometric measurements to distinguish Aryans from Jews and many forms of anthropometry were used for the advocacy of eugenics. During the 1920s and 1930s, though, members of the school of cultural anthropology of Franz Boas began to use anthropometric approaches to discredit the concept of fixed biological race. Boas ...
A Bertillon record for Francis Galton, from a visit to Bertillon's laboratory in 1893. The history of anthropometry includes and spans various concepts, both scientific and pseudoscientific, such as craniometry, paleoanthropology, biological anthropology, phrenology, physiognomy, forensics, criminology, phylogeography, human origins, and cranio-facial description, as well as correlations ...
1742 — Anders Celsius proposed a temperature scale in which 100 represented the temperature of melting ice and 0 represented the boiling point of water at 25 inches and 3 lines of barometric mercury height. [8] This corresponds to 751.16 mm, [9] so that on the present-day definition, this boiling point is 99.67 degrees Celsius. [10]
The polar bear has stocky limbs and very short ears that are in accordance with the predictions of Allen's rule, so does the snow leopard. [5] In 2007, R.L. Nudds and S.A. Oswald studied the exposed lengths of seabirds ' legs and found that the exposed leg lengths were negatively correlated with Tm axdiff (body temperature minus minimum ambient ...
Torricelli concluded that the mercury fluid in the tube is aided by the atmospheric pressure that is present on the surface of mercury fluid on the dish. He also stated that the changes of liquid level from day to day are caused by the variation of atmospheric pressure. The empty space in the tube is called the Torricellian vacuum. [3] 760 mmHg ...
One U.S. Forest Service fire chief by the name of Howard Flint gave the idea a go in the early 1930s, kicking a beer keg filled with water out of an airplane as it soared over Felts Field airport ...
Some introductory physics textbooks still define the pressure-temperature relationship as Gay-Lussac's law. [ 6 ] [ 7 ] [ 8 ] Gay-Lussac primarily investigated the relationship between volume and temperature and published it in 1802, but his work did cover some comparison between pressure and temperature.

Lambert Adolphe Jacques Quetelet FRSF or FRSE (French: ⓘ; 22 February 1796 – 17 February 1874) [1] was a Belgian astronomer, mathematician, statistician and sociologist who founded and directed the Brussels Observatory and was influential in introducing statistical methods to the social sciences.
