  2. Buffon's needle problem - Wikipedia

    en.wikipedia.org/wiki/Buffon's_needle_problem

    In probability theory, Buffon's needle problem is a question first posed in the 18th century by Georges-Louis Leclerc, Comte de Buffon: [1] Suppose we have a floor made of parallel strips of wood , each the same width, and we drop a needle onto the floor.

    en.wikipedia.org/wiki/Buffon's_noodle

    In geometric probability, the problem of Buffon's noodle is a variation on the well-known problem of Buffon's needle, named after Georges-Louis Leclerc, Comte de Buffon who lived in the 18th century. This approach to the problem was published by Joseph-Émile Barbier in 1860.

  5. Collision theory - Wikipedia

    en.wikipedia.org/wiki/Collision_theory

    Collision theory is a principle of chemistry used to predict the rates of chemical reactions. It states that when suitable particles of the reactant hit each other with the correct orientation, only a certain amount of collisions result in a perceptible or notable change; these successful changes are called successful collisions.

  6. Georges-Louis Leclerc, Comte de Buffon - Wikipedia

    en.wikipedia.org/wiki/Georges-Louis_Leclerc...

    Georges Louis Leclerc (later Comte de Buffon) was born at Montbard, in the province of Burgundy to Benjamin François Leclerc, a minor local official in charge of the salt tax and Anne-Christine Marlin, also from a family of civil servants.

  7. Collision response - Wikipedia

    en.wikipedia.org/wiki/Collision_response

    The degree of relative kinetic energy retained after a collision, termed the restitution, is dependent on the elasticity of the bodies‟ materials.The coefficient of restitution between two given materials is modeled as the ratio [] of the relative post-collision speed of a point of contact along the contact normal, with respect to the relative pre-collision speed of the same point along the ...

  8. Steric factor - Wikipedia

    en.wikipedia.org/wiki/Steric_factor

    Also called the probability factor, the steric factor is defined as the ratio between the experimental value of the rate constant and the one predicted by collision theory. It can also be defined as the ratio between the pre-exponential factor and the collision frequency , and it is most often less than unity.

  9. Mean free time - Wikipedia

    en.wikipedia.org/wiki/Mean_free_time

    Molecules in a fluid constantly collide with each other. The mean free time for a molecule in a fluid is the average time between collisions. The mean free path of the molecule is the product of the average speed and the mean free time. [1] These concepts are used in the kinetic theory of gases to compute transport coefficients such as the ...
