    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics. This article contains the list of certain mnemonics in chemistry.

  3. Expression templates - Wikipedia

    en.wikipedia.org/wiki/Expression_templates

    Expression templates implement delayed evaluation using expression trees that only exist at compile time. Each assignment to a Vec, such as Vec x = a + b + c, generates a new Vec constructor if needed by template instantiation. This constructor operates on three Vec; it allocates the necessary memory and then performs the computation. Thus only ...

    en.wikipedia.org/wiki/USA_Memory_Championship

    There is now an online qualifier consisting of five events: two from the popular brain-training site Lumosity, and three events from the online memory competition website Memory League. The two events from Lumosity have typically been Memory Match Overdrive and Rotation Matrix, while the events from Memory League have been Images, Names, and ...

  5. Pattern recognition (psychology) - Wikipedia

    en.wikipedia.org/wiki/Pattern_recognition...

    Template matching theory describes the most basic approach to human pattern recognition. It is a theory that assumes every perceived object is stored as a "template" into long-term memory. [4] Incoming information is compared to these templates to find an exact match. [5]

  7. Luminosity (scattering theory) - Wikipedia

    en.wikipedia.org/wiki/Luminosity_(scattering_theory)

    In scattering theory and accelerator physics, luminosity (L) is the ratio of the number of events detected (dN) in a certain period of time (dt) to the cross-section (σ): [1]

    For example, consider a 10 W transmitter at a distance of 1 million metres, radiating over a bandwidth of 1 MHz. By the time that power has reached the observer, the power is spread over the surface of a sphere with area 4 πr 2 or about 1.26×10 13 m 2 , so its flux density is 10 / 10 6 / (1.26×10 13 ) W m −2 Hz −1 = 8×10 7 Jy .

    Those stars have also been used as a calibration sample for Kepler candidate objects. Besides avoiding the discontinuity in the exponent at M = 0.43 M ⊙ , the relation also recovers a = 4.0 for M ≃ 0.85 M ⊙ .
