Lagrange point

Named after Joseph Louis Lagrange, who discovered the points L₄ and L₅, building on earlier work by Leonhard Euler, and in 1772 published an essay on the three-body problem.

Mathematically, the Lagrange points represent solutions to a restricted form of the three body problem in which the mass of one object is assumed negligible compared to that of the two principal bodies—as, for example, an artificial satellite and the Earth-Moon system.

Lagrange points are significant for lunar development in that raw materials, such as near-Earth objects (NEOs) can be safely stored at L-4 and L-5 prior to mining and processing.

2008, David Schrunk, Burton Sharpe, Bonnie L. Cooper, Madhu Thangavelu, The Moon: Resources, Future Development and Settlement, Springer, Praxis Publishing, page 57:

The $1.27-billion (1 billion euros) SOHO satellite was launched in 1995 and is flying a joint mission between NASA and the European Space Agency (ESA). It watches solar activity from an orbit about the Lagrange Point 1, a gravitationally stable spot between Earth and the sun that is about 932,000 miles (1.5 million kilometers) from our planet.

By bringing together the rhombohedron and the scalenohedron, as has been done in Fig. 119, it will be noticed that the lateral edges of the two forms have a similar position towards the axes, so that for every scalenohedron there must be a rhombohedron whose lateral edges coincide with the lateral edges of the other form. This rhombohedron is called the inscribed rhombohedron of the scalenohedron.

1984, Natalie Myra Rosinsky, Feminist futures--contemporary women's speculative fiction, page 29:

(physics) The study of the orientation dynamics of nematic (flowless) liquid crystals


microcrith

An atom of oxygen weighs sixteen microcriths.

1872, Josiah Parsons Cooke (Jr.), Principles of Chemical Philosophy
It will perhaps serve to give greater definiteness to our conceptions if , even at the risk of coining a new word , we call the unit of molecular weights a microcrith .

(physics, obsolete) The weight of the half hydrogen molecule, or of the hydrogen atom, taken as the standard in comparing the atomic weights of the elements.


intervacuum

Formed as inter- + vacuum, but compare the Latin intervacō (“I am empty between”).

UHV technique for intervacuum sample transfer...

1990, Gerardo Beni, Vacuum mechatronics:

The intervacuum space was monitored continuously, a change in pressure implied to a rupture of the isolation between this volume and either the torus or waveguide vacuums.

2003, Gerardo Giruzzi, EC-12: proceedings of the 12th Joint Workshop on Electron Cyclotron Emission...:

(physics) Between regions of vacuum (or of very low pressure)


Secchi disk

Secchi + disk. From Italian Secchi, from Angelo Secchi.

A circular disk used to measure water transparency (and thus turbidity)


cubooctahedron

cubooctahedron (plural cubooctahedrons or cubooctahedra)

cubooctahedrons (plural)
cubooctahedra (plural)

(crystallography) A combination of a cube and octahedron, especially one in which the octahedral faces meet at the middle of the cubic edges.


phonomotor

(physics, historical) An instrument in which motion is produced by sound waves.
