  2. Gas constant - Wikipedia

    en.wikipedia.org/wiki/Gas_constant

    This disparity is not a significant departure from accuracy, and USSA1976 uses this value of R ∗ for all the calculations of the standard atmosphere. When using the ISO value of R , the calculated pressure increases by only 0.62 pascal at 11 kilometres (the equivalent of a difference of only 17.4 centimetres or 6.8 inches) and 0.292 Pa at 20 ...

    Schematic figure of a Brownian ratchet. In the philosophy of thermal and statistical physics, the Brownian ratchet or Feynman–Smoluchowski ratchet is an apparent perpetual motion machine of the second kind (converting thermal energy into mechanical work), first analysed in 1912 as a thought experiment by Polish physicist Marian Smoluchowski.

  4. R (cross section ratio) - Wikipedia

    en.wikipedia.org/wiki/R_(cross_section_ratio)

    R is an important input in the calculation of the anomalous magnetic dipole moment. [1] Experimental values have been measured for center-of-mass energies from 400 MeV to 150 GeV. [2] R also provides experimental confirmation of the electric charge of quarks, in particular the charm quark and bottom quark, and the existence of three quark ...

  5. Rube Goldberg machine - Wikipedia

    en.wikipedia.org/wiki/Rube_Goldberg_machine

    A Rube Goldberg machine, named after American cartoonist Rube Goldberg, is a chain reaction–type machine or contraption intentionally designed to perform a simple task in an indirect and (impractically) overly complicated way. Usually, these machines consist of a series of simple unrelated devices; the action of each triggers the initiation ...

    The machine is able to store one decimal number in each column. The machine can only add the value of a column n + 1 to column n to produce the new value of n. Column N can only store a constant, column 1 displays (and possibly prints) the value of the calculation on the current iteration.
