CRYOGENICS |
|
Cryogenics is a branch of physics (or engineering) that studies the production of very low temperatures (below −150°C, −238°F or 123K) and the behavior of materials at those temperatures. Cryonics is the nascent technology of cryopreserving humans and animals with the intention of future revival. Unlike cryogenics and cryobiology, cryonics is not an established science and is viewed with skepticism by most scientists and doctors today (although there are many scientists involved in cryonics[1]). As a technology, cryonics seeks to apply the results of many sciences, including cryobiology, cryogenics, rheology, emergency medicine, etc.

ESCALATOR |
|
An escalator is a conveyor transport device for transporting people, consisting of a staircase whose steps move up or down on tracks that keep the surfaces of the individual steps horizontal.
A moving walkway, moving sidewalk, travelator, or travellator is a slow conveyor belt that transports people horizontally or on an incline in a similar manner to an escalator. In both cases, riders can walk or stand. The walkways are often supplied in pairs, one for each direction.
