The superconducting gravimeter achieves sensitivities of 10 –11 m·s −2 (one nanogal), approximately one trillionth (10 −12) of the Earth surface gravity. In a demonstration of the sensitivity of the superconducting gravimeter, Virtanen (2006), [ 8 ] describes how an instrument at Metsähovi, Finland, detected the gradual increase in ...
The Lunar Traverse Gravimeter was a lunar science experiment, deployed by astronauts on the lunar surface in 1972 as part of Apollo 17.The goal of the experiment was to use relative gravity measurements to infer potential attributes about the geological substrata near the Apollo 17 landing site.
James Franklin Hyde was born in Solvay, New York on March 11, 1903. He attended Solvay High School and graduated on June 25, 1919, at the age of 16. [1] He was partly encouraged by one of his science teachers to enter into the field of science.
Gravimeter with variant of Repsold pendulum The large increase in gravity measurement accuracy made possible by Kater's pendulum established gravimetry as a regular part of geodesy . To be useful, it was necessary to find the exact location (latitude and longitude) of the 'station' where a gravity measurement was taken, so pendulum measurements ...
Physical chemistry: Mikhail Lomonosov (1711–1765) The first to read lectures in physical chemistry and coin the term (1752). Jacobus van 't Hoff (1852–1911) Jacobus van 't Hoff is considered one of the founders of the discipline of physical chemistry. His work helped found the discipline as it is today. [71] [72] [73] Svante Arrhenius (1859 ...
The Open Syllabus Project (OSP) is an online open-source platform that catalogs and analyzes millions of college syllabi. [3] Founded by researchers from the American Assembly at Columbia University , the OSP has amassed the most extensive collection of searchable syllabi.
The Indian Certificate of Secondary Education (ICSE) is a certificate awarded upon satisfactory result in an examination conducted by the Council for the Indian School Certificate Examinations, a private board designed to provide an examination in a course of general education, in accordance with the recommendations of the New Education Policy 2020 (), through the medium of English.
Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. . This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and ...
