  2. Additive rhythm and divisive rhythm - Wikipedia

    en.wikipedia.org/wiki/Additive_rhythm_and...

    Additive rhythm in 3+3+2 8 time Additive rhythm 3+3+2 8 time. 1 whole note = 8 eighth notes = 3 + 3 + 2. The term additive rhythm is also often used to refer to what are also incorrectly called asymmetric rhythms and even irregular rhythms [citation needed] – that is, meters which have a regular pattern of beats of uneven length.

  3. Triple-alpha process - Wikipedia

    en.wikipedia.org/wiki/Triple-alpha_process

    Nuclear fusion reaction of two helium-4 nuclei produces beryllium-8, which is highly unstable, and decays back into smaller nuclei with a half-life of 8.19 × 10 −17 s, unless within that time a third alpha particle fuses with the beryllium-8 nucleus [3] to produce an excited resonance state of carbon-12, [4] called the Hoyle state, which ...

  4. Lawson criterion - Wikipedia

    en.wikipedia.org/wiki/Lawson_criterion

    Lawson criterion of important magnetic confinement fusion experiments. The Lawson criterion is a figure of merit used in nuclear fusion research. It compares the rate of energy being generated by fusion reactions within the fusion fuel to the rate of energy losses to the environment.

  5. Princeton field-reversed configuration - Wikipedia

    en.wikipedia.org/wiki/Princeton_field-reversed...

    The experiment probes the dynamics of long-pulse, collisionless, [1] low s-parameter [2] field-reversed configurations (FRCs) formed with odd-parity rotating magnetic fields. [3] [4] FRCs are the evolution of the Greek engineer's Nicholas C. Christofilos original idea of E-layers which he developed for the Astron fusion reactor. [5]

  6. Entropy of fusion - Wikipedia

    en.wikipedia.org/wiki/Entropy_of_fusion

    In thermodynamics, the entropy of fusion is the increase in entropy when melting a solid substance. This is almost always positive since the degree of disorder increases in the transition from an organized crystalline solid to the disorganized structure of a liquid ; the only known exception is helium . [ 1 ]

  7. Fusion power - Wikipedia

    en.wikipedia.org/wiki/Fusion_power

    3 Li → 3 1 T + 4 2 He 1 0 n + 7 3 Li → 3 1 T + 4 2 He + 1 0 n. The reactant neutron is supplied by the D-T fusion reaction shown above, and the one that has the greatest energy yield. The reaction with 6 Li is exothermic, providing a small energy gain for the reactor. The reaction with 7 Li is endothermic, but does not consume the neutron ...

  8. Singly and doubly even - Wikipedia

    en.wikipedia.org/wiki/Singly_and_doubly_even

    These names reflect a basic concept in number theory, the 2-order of an integer: how many times the integer can be divided by 2. Specifically, the 2-order of a nonzero integer n is the maximum integer value k such that n/2 k is an integer. This is equivalent to the multiplicity of 2 in the prime factorization.

  9. Lumines: Puzzle Fusion - Wikipedia

    en.wikipedia.org/wiki/Lumines:_Puzzle_Fusion

    Lumines: Puzzle Fusion is a falling block puzzle game. [2] [3] The objective is to arrange grouped blocks descending from the top of a 16×10 grid playing field to create single-color squares once they have landed. [4] Grouped blocks have a 2×2 shape and vary between two colors. [2]
