  2. HP 35s - Wikipedia

    en.wikipedia.org/wiki/HP_35s

    The HP 35s (F2215A) is a Hewlett-Packard non-graphing programmable scientific calculator. Although it is a successor to the HP 33s, it was introduced to commemorate the 35th anniversary of the HP-35, Hewlett-Packard's first pocket calculator (and the world's first pocket scientific calculator). HP also released a limited production anniversary ...

  3. Automatic calculation of particle interaction or decay

    en.wikipedia.org/wiki/Automatic_calculation_of...

    The automatic calculation of particle interaction or decay is part of the computational particle physics branch. It refers to computing tools that help calculating the complex particle interactions as studied in high-energy physics , astroparticle physics and cosmology .

  4. HP-35 - Wikipedia

    en.wikipedia.org/wiki/HP-35

    Was the first scientific calculator to fly in space in 1973. [5] HP-35 calculators were carried on the Skylab 3 and Skylab 4 flights, between July 1973 and February 1974. [6] Is the first pocket calculator with a numeric range that covered 200 decades (more precise 199, ±10 ±99). [5]

  5. HP calculators - Wikipedia

    en.wikipedia.org/wiki/HP_calculators

    HP's first scientific calculator, HP-35 With this in mind, HP built the HP 9100 desktop scientific calculator. This was a full-featured calculator that included not only standard "adding machine" functions but also powerful capabilities to handle floating-point numbers, trigonometric functions , logarithms, exponentiation, and square roots .

  6. Bateman equation - Wikipedia

    en.wikipedia.org/wiki/Bateman_equation

    In nuclear physics, the Bateman equation is a mathematical model describing abundances and activities in a decay chain as a function of time, based on the decay rates and initial abundances. The model was formulated by Ernest Rutherford in 1905 [1] and the analytical solution was provided by Harry Bateman in 1910. [2]

  7. HP-20S - Wikipedia

    en.wikipedia.org/wiki/HP-20S

    The HP-20S (F1890A) is an algebraic programmable scientific calculator produced by Hewlett-Packard from 1987 to 2000.. A member of HP's Pioneer series, the 20S was a low cost model targeted at students, using the same hardware as the HP-10B business calculator.

  8. Half-life - Wikipedia

    en.wikipedia.org/wiki/Half-life

    There is a half-life describing any exponential-decay process. For example: As noted above, in radioactive decay the half-life is the length of time after which there is a 50% chance that an atom will have undergone nuclear decay. It varies depending on the atom type and isotope, and is usually determined experimentally. See List of nuclides.

  9. Decay correction - Wikipedia

    en.wikipedia.org/wiki/Decay_correction

    The decay correct might be used this way: a group of 20 animals is injected with a compound of interest on a Monday at 10:00 a.m. The compound is chemically joined to the isotope copper-64, which has a known half-life of 12.7 hours, or 764 minutes.
