Fr.: pont d'Anderson
A. Anderson (1891, Phil. Mag. (5) 31, 329); → bridge.
1) An apparent structure of → gas or
→ stars linking one → galaxy
to another, such as → Magellanic Bridge.
M.E. brigge, O.E. brycge, from P.Gmc. *brugjo (cf. Ger. Brücke), from PIE *bhru- "log, beam."
Pol, Mid.Pers. puhl,, Av. pərətav- "bridge, passage."
Fr.: pont d'Einstein-Rosen
A hypothetical structure that can join two distant regions of → space-time through a tunnel-like shortcut, as predicted by → general relativity. The Einstein-Rosen bridge is based on the → Schwarzschild solution of → Einstein's field equations. It is the simplest type of → wormholes.
Albert Einstein & Nathan Rosen (1935, Phys.Rev. 48, 73); → bridge.
Fr.: pont magellanique
A filament of → neutral hydrogen which connects the → Small Magellanic Cloud and → Large Magellanic Cloud. The Magellanic Bridge appears to result from a → close encounter between these two galaxies some 200 million years ago.
Fr.: pont de Maxwell
Fr.: pont d'Orion
Same as → Orion Arm.
Fr.: pont de Wheatstone
An device consisting of four → resistances in series, used to determine the value of an unknown electrical resistance when the other three resistances are known.
Named after Charles Wheatstone (1802-1875), British physicist, who extensively used the circuit (1843) but was not its inventor. Such an arrangement of four resistances was first used by Samuel Hunter Christie (1784-1865) in 1833; → bridge.
