    en.wikipedia.org/wiki/Heisenberg's_microscope

    Heisenberg's microscope is a thought experiment proposed by Werner Heisenberg that has served as the nucleus of some commonly held ideas about quantum mechanics.In particular, it provides an argument for the uncertainty principle on the basis of the principles of classical optics.

  3. Low insertion force - Wikipedia

    en.wikipedia.org/wiki/Low_insertion_force

    Low insertion force (LIF) is a technology used in integrated circuit sockets that are designed so the force required to insert or remove a package is low. [ 1 ] Initially, the LIF connectors were designed as a cheaper alternative compared to zero insertion force (ZIF) connectors, to facilitate programming and testing of equipment.

  4. Desoldering - Wikipedia

    Removal of these chips can be problematic as it is impossible to heat all of the leads at once with a standard soldering iron. It is possible to remove them with the use of a razor blade or a high-rpm craft tool, simply by cutting off the leads. The stubs are then easy to melt off and clean with a soldering iron.

    Socket set with ratchet (above), four hex sockets and a universal joint. A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt.

    A 1/2" drive pistol-grip air impact wrench. An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft.

  8. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. [1] It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter Bauman. [1]

  9. CPU socket - Wikipedia

    en.wikipedia.org/wiki/CPU_socket

    It is possible to use Socket 7 processors in a Socket 5. An adapter is required, or if one is careful, a socket 7 can be pulled off its pins and put onto a socket 5 board, allowing the use of socket 7 processors. Socket 8: 1995 Intel Pentium Pro: PGA: 387 ? 60–66 MHz Slot 1: 1997 Intel Pentium II Intel Pentium III: Desktop Slot: 242 ? 66 ...
