Tensegrity, tensional integrity or floating compression, is a structural principle based on the use of isolated components in compression inside a net of continuous tension, in such a way that the compressed members ( usually bars or struts ) do not touch each other and the prestressed tensioned members ( usually cables or tendons ) delineate the system spatially.

Workshops in the past have been on Cinematography, Embedded Linux, Tensegrity, Smart Materials, Ornithopter and more.

Tensegrity structures are structures based on the combination of a few simple design patterns:

This is the only model to date that provides biological cells with a mechanism capable of pre-stressing flexible, membrane-associated protein networks, which is absent from Glanz & Ingbers ' exclusively protein-based models of cellular “ Tensegrity ” structures.

Tensegrity domes, patented by Buckminster Fuller in 1962, are fabric-covered structures consisting of radial trusses made from steel cables under tension with vertical steel pipes spreading the cables into the truss form.

Tensegrity as " The Architecture of Life " is an idea developed by Donald E. Ingber, explained in a January 1998 article in Scientific American and further discussed at the blog " Tensegrity ".

Tensegrity in molecular biology has been developed by Donald Ingber.

Carbon molecules known as fullerenes were later named by scientists for their resemblance to geodesic spheres.

Geodesic domes are the upper portion of geodesic spheres.

This phenomenon of geodesic deviation means that inertial frames of reference do not exist globally as they do in Newtonian mechanics and special relativity.

There are experiments using geodesic grids and icosahedral grids, which ( being more uniform ) do not have pole-problems.

They do not correspond to the path of any physical particle, but in a space that has space-sections orthogonal to a timelike Killing vector a spacelike geodesic ( with its affine parameter ) within such a space section represents the graph of a tightly stretched, massless filament.

This and related predictions follow from the fact that light follows what is called a light-like or null geodesic — a generalization of the straight lines along which light travels in classical physics.

This leads one to consider the problem of determining to what extent any situation approximates true geodesic motion.

From 1919 to 1967 they were produced by Head geodesic administration (), then by Chief administration of geodesy and cartography ().

In this case, for two events which are simultaneous according the cosmological time coordinate, the value of the cosmological proper distance is not equal to the value of the proper length between these same events ,( Wright ) which would just be the distance along a straight line between the events in a Minkowski diagram ( and a straight line is a geodesic in flat Minkowski spacetime ), or the coordinate distance between the events in the inertial frame where they are simultaneous.

If the Cauchy surface were compact, i. e. space is compact, the null geodesic generators of the boundary can intersect everywhere because they can intersect on the other side of space.

In particular geodesics have zero geodesic curvature ( they are " straight "), and that is their definition, so that, which explains why they appear to be curved in ambient space whenever the submanifold is.

Great circles have curvature, which implies zero geodesic curvature, thus they are geodesics.

Trumbull's participation and success on " Andromeda " set him up to direct the 1971 film Silent Running, with a script based on his original treatment: America's last great forests are preserved and sent into space inside huge geodesic domes, in the hope that one day they can be returned to an earth that can once again sustain them.

Physically, these describe different universes in which all the same events and interactions are still ( causally ) possible, but a new additional force is necessary to effect this ( that is, replication of all the same trajectories would necessitate departures from geodesic motion because the metric is different ).

The geodesic dome appealed to Fuller because it was extremely strong for its weight, its " omnitriangulated " surface provided an inherently stable structure, and because a sphere encloses the greatest volume for the least surface area.

The map t → t < sup > 2 </ sup > from the unit interval to itself gives the shortest path between 0 and 1, but is not a geodesic because the velocity of the corresponding motion of a point is not constant.

The usual straight line emanating from 1, namely y ( t ) = 1 + xt covers the same path as a geodesic, of course, except we have to reparametrize so as to get a curve with constant speed (" constant speed ", remember, is not going to be the ordinary constant speed, because we're using this funny metric ).

is sometimes called the energy or action of the curve ; this name is justified because the geodesic equations are the Euler – Lagrange equations of motion for this action.

An object in free fall does not experience a force, because it is following a geodesic.

In light of this, the bucket of water rotating in empty space will experience a force because it rotates with respect to the geodesic.

The water will become concave, not because it is rotating with respect to the distant stars, but because it is rotating with respect to the geodesic.

because it is the length of the graph geodesic between those two vertices.
