  2. Lanchester's laws - Wikipedia

    en.wikipedia.org/wiki/Lanchester's_laws

    Lanchester's laws are mathematical formulas for calculating the relative strengths of military forces.The Lanchester equations are differential equations describing the time dependence of two armies' strengths A and B as a function of time, with the function depending only on A and B. [1] [2]

  3. Attribute (role-playing games) - Wikipedia

    en.wikipedia.org/wiki/Attribute_(role-playing_games)

    A measure of how physically strong a character is. Strength often controls the power and/or damage of melee attacks, the maximum weight the character can carry, and sometimes hit points. Armor and weapons might also have a Strength requirement to use them. Constitution aka Stamina, Endurance, Vitality, Recovery ...

  4. Nuclear weapon yield - Wikipedia

    en.wikipedia.org/wiki/Nuclear_weapon_yield

    Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...

  5. Power projection - Wikipedia

    en.wikipedia.org/wiki/Power_projection

    Power projection (or force projection or strength projection) in international relations is the capacity of a state to deploy and sustain forces outside its territory. [1] The ability of a state to project its power into an area may serve as an effective diplomatic lever, influencing the decision-making processes and acting as a potential deterrent on other states' behavior.

  6. Hudson's equation - Wikipedia

    en.wikipedia.org/wiki/Hudson's_equation

    Hudson's equation, also known as Hudson formula, is an equation used by coastal engineers to calculate the minimum size of riprap (armourstone) required to provide satisfactory stability characteristics for rubble structures such as breakwaters under attack from storm wave conditions.

  7. Numeric precision in Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Numeric_precision_in...

    Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

  8. Peukert's law - Wikipedia

    en.wikipedia.org/wiki/Peukert's_law

    If Peukert's constant , the exponent, were equal to unity, the delivered capacity would be independent of the current. For a real battery the exponent is greater than unity, and capacity decreases as discharge rate increases. For a lead–acid battery is typically between 1.1 and 1.3.

  9. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    The ballistic tables are made up for a factitious projectile being defined as: "a factitious weight and with a specific shape and specific dimensions in a ratio of calibers". This simplifies calculation for the ballistic coefficient of a standard model projectile, which could mathematically move through the standard atmosphere with the same ...
