  2. IP code - Wikipedia

    en.wikipedia.org/wiki/IP_Code

    IP65 touchscreen display IP65 LED lamp. The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against ...

    en.wikipedia.org/wiki/Double-slit_experiment

    A diagram of Wheeler's delayed choice experiment, showing the principle of determining the path of the photon after it passes through the slit Wheeler's delayed-choice experiments demonstrate that extracting "which path" information after a particle passes through the slits can seem to retroactively alter its previous behavior at the slits.

    The emergence of the muons is caused by the collision of cosmic rays with the upper atmosphere, after which the muons reach Earth. The probability that muons can reach the Earth depends on their half-life, which itself is modified by the relativistic corrections of two quantities: a) the mean lifetime of muons and b) the length between the upper and lower atmosphere (at Earth's surface).

  6. Dielectric withstand test - Wikipedia

    en.wikipedia.org/wiki/Dielectric_withstand_test

    In electrical engineering, a dielectric withstand test (also pressure test, high potential test, hipot test, or insulation test) is an electrical safety test performed on a component or product to determine the effectiveness of its insulation. The test may be between mutually insulated sections of a part, or energized parts and ground.

  7. Network topology - Wikipedia

    en.wikipedia.org/wiki/Network_topology

    Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. [1] [2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [3] industrial fieldbusses and computer networks.

  8. Precision tests of QED - Wikipedia

    en.wikipedia.org/wiki/Precision_tests_of_QED

    Precision tests of QED have been performed in low-energy atomic physics experiments, high-energy collider experiments, and condensed matter systems. The value of α is obtained in each of these experiments by fitting an experimental measurement to a theoretical expression (including higher-order radiative corrections) that includes α as a parameter.

  9. Induced polarization - Wikipedia

    en.wikipedia.org/wiki/Induced_polarization

    Induced polarization (IP) is a geophysical imaging technique used to identify the electrical chargeability of subsurface materials, such as ore. [ 1 ] [ 2 ] The polarization effect was originally discovered by Conrad Schlumberger when measuring the resistivity of rock.
