hyperloops

Noun

hyperloop (plural hyperloops)

1. A theoretical high-speed transportation system, proposed by Elon Musk, in which pressurized capsules ride on an air cushion driven by linear induction motors and air compressors through reduced-pressure tubes.
   • Musk began developing another transportation project in 2012, something he calls the Hyperloop.2012, Scott Griffiths, Eric Elfman, Beyond Genius, →ISBN, page 210
2. A control structure in which a loop repeats until either a stopping condition is met or all possible values of the looping index have been checked.
   • If Hal finds a value of x such that fun(x), Hal sends a signal to Dave (perhaps a light-beam). Dave carries a receiving device with him, which stores a variable, xFound, initialised to a default value of 0; this receiver sets xFound to 1 on (and only on) receipt of a signal from Hal. Once Dave...2009, Klaus Ambos-Spies, Benedikt Löwe, Wolfgang Merkle, Mathematical Theory and Computational Practice, →ISBN, page 70
3. (quantum mechanics) A quantum mechanical paradox resulting from the observer being a product of the observations that it makes.
   • At this point, the hyperloop breaks in. A holographic virtual image is presented to an optical observer. Where is the observer of the image formed from Gij? Presumably, it is the physicist. But the physicist is himself an image projected from the same source. We still have a self-viewing system...1984, Alex Comfort, Reality and Empathy, →ISBN
