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.
A gravimeter is an instrument used to measure ... a secret military technology developed in the 1950–1960s as a ... They also invented most subsequent refinements ...
In the late 1880s Granville invented the electric vibrator, a handheld electric operated device designed to relieve male muscle aches and pains. [ 2 ] [ 3 ] Originally called a percusser or more colloquially "Granville's hammer", the machine was manufactured and sold to physicians.
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 ...
He pointed out the 1962 paper and mentioned the possibility of detecting gravitational waves if the interferometric technology and measuring techniques improved. Since the early 1990s, physicists have thought that technology has evolved to the point where detection of gravitational waves—of significant astrophysical interest—is now possible ...
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.
It is hypothesized that gravitational interactions are mediated by an as yet undiscovered elementary particle, dubbed the graviton.The three other known forces of nature are mediated by elementary particles: electromagnetism by the photon, the strong interaction by gluons, and the weak interaction by the W and Z bosons.
A "Helicorder" drum was a device used to record data into photographic paper or in the form of paper and ink. A "Develocorder" was a machine that record data from up to 20 channels into a 16-mm film. The recorded film can be viewed by a machine. The reading and measuring from these types of media can be done by hand.
