While the L5 Society failed to achieve the goal of human settlements in space, it served as a focal point for many of the people who later became known in fields such as nanotechnology, memetics, extropianism, cryonics, transhumanism, artificial intelligence, and tether propulsion, such as K. Eric Drexler, Robert Forward, and Hans Moravec.

There are five Lagrange points for the Sun–Earth system, and five different Lagrange points for the Earth–Moon system. L 1, L 2, and L 3 are on the line through the centers of the two large bodies, while L 4 and L 5 each act as the third vertex of an equilateral triangle formed with the centers of the two large bodies.

L4 and L5 are points of gravitational equilibrium located on the Moon’s orbit at equal distances from both the Earth and the Moon. An object placed in orbit around L5 (or L4) will remain there indefinitely without having to expend fuel to keep it in position.

2020年6月29日 · The most famous of the Lagrange points is L5, which was to be the location of a space colony proposed by Gerard K. O’Neill in the article The Colonization of Space which appeared in the September, 1974 issue of Physics Today.

The L5-S1 spinal motion segment, also called the lumbosacral joint, is the transition region between the lumbar spine and sacral spine in the lower back. In this region, the curvature of the spine changes from lumbar lordosis (forward curve) to sacral kyphosis (backward curve). L5-S1 helps transfer loads from the spine into the pelvis and legs.

L5 is the fifth Lagrangian Libration point. But what are libration points? They are locations where a spacecraft may be placed so as always to remain in the same position with respect to the Earth and the Moon. The French mathematician, Lagrange, in …

Conditions affecting the L5-S1 spinal motion segment are usually treated with nonsurgical methods. If the lower back and/or leg symptoms worsen or do not improve despite these treatments, or in case of certain medical emergencies, such as tumors or cauda equina syndrome, surgery may be recommended. Treatment of L5-S1 usually begins with:

Together with the intervertebral disc, joints, nerves, and soft tissues, the L4-L5 spinal motion segment provides a variety of functions, including supporting the upper body and allowing trunk motion in multiple directions. 1 Waldman SD. Functional Anatomy of …

Lagrange point colonization is a proposed form of space colonization [1] of the five equilibrium points in the orbit of a planet or its primary moon, called Lagrange points. The Lagrange points L 4 and L 5 are stable if the mass of the larger body is at …

2012年12月15日 · The L5 Society was put together because people wanted to do exactly that. They wanted to start building at L5, and eventually create space colonies filled with plants, animals, and people.
