LaCoste's most famous invention is the ship- and aircraft-mounted gravimeter. These revolutionized exploration for minerals by allowing wide-ranging geological surveys. The chief problem that Lacoste defeated was to distinguish the accelerations of the vehicles from the accelerations due to gravity, and measure the minute changes in gravity.
The modern gravimeter was developed by Lucien LaCoste and Arnold Romberg in 1936. They also invented most subsequent refinements, including the ship-mounted gravimeter, in 1965, temperature-resistant instruments for deep boreholes, and lightweight hand-carried instruments.
Now it became possible to measure gravity more accurately. Vening Meinesz started with measuring gravity all over the Netherlands, for which a network of 51 monitoring stations was created. This became a success, which encouraged him to do measurements at sea. A perfected gravimeter, hanging in a "swing", was designed. The experiment was ...
James Goodfellow (born 1937) is a Scottish inventor.In 1966, he patented personal identification number (PIN) technology and an automated teller machine (ATM). [1] [2] He is generally considered the inventor of the modern ATM.
James E. Faller (January 17, 1934 – June 14, 2023) was an American physicist and inventor who specialized in the field of gravity.He conceived the Lunar Laser Ranging Program, the goal of which, was to fire high powered laser beams at special retroreflectors placed on the Moon by Apollo program Astronauts.
John Adrian Shepherd-Barron was born on 23 June 1925 in Shillong (now Meghalaya), India, to British parents.His Scottish father, Wilfred Shepherd-Barron, was chief engineer of the Chittagong Port Commissioners in North Bengal, which was then part of the British Empire, then later Chief Engineer of the Port of London Authority, before becoming president of the Institution of Civil Engineers ...
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 ...
Philippe Bouyer (born 7 March 1969) is a French physicist and researcher, professor at the University of Amsterdam and the Technical University of Eindhoven, and chairman of the Dutch Quantum Initiative, Quantum Delta NL. He co-founded Muquans, acquired later by Exail, a company specializing in quantum technology-based gravimeters. [1]
