Gravimeter with variant of Repsold–Bessel pendulum An Autograv CG-5 gravimeter being operated. A gravimeter is an instrument used to measure gravitational acceleration. Every mass has an associated gravitational potential. The gradient of this potential is a force. A gravimeter measures this gravitational force.
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.
Dennis MacAlistair Ritchie (September 9, 1941 – c. October 12, 2011) was an American computer scientist. [3] He created the C programming language and the Unix operating system and B language with long-time colleague Ken Thompson. [3]
The book The C Programming Language, co-authored by the original language designer, served for many years as the de facto standard for the language. [ 12 ] [ 1 ] C has been standardized since 1989 by the American National Standards Institute (ANSI) and, subsequently, jointly by the International Organization for Standardization (ISO) and the ...
He also invented the B programming language, the direct predecessor to the C language, and was one of the creators and early developers of the Plan 9 operating system. Since 2006, Thompson has worked at Google , where he co-developed the Go language .
The C Programming Language (sometimes termed K&R, after its authors' initials) is a computer programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the C programming language, as well as co-designed the Unix operating system with which development of the language was closely intertwined.
The instrument was a gravimeter, based on the LaCoste and Romberg D-meter, [22] that primarily consists of an adjustable mass on a sprung lever attached to the instrument's measurement electronics. [ 6 ] : 4 [ 22 ] The experiment had a total mass of 12.7 kg, a volume of 26,970 cm 3 , and utilised a maximum of 9.3 W of power.
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.
