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.
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.
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.

The r-to-1 collision problem is an important theoretical problem in complexity theory, quantum computing, and computational mathematics. The collision problem most often refers to the 2-to-1 version: [ 1 ] given n {\displaystyle n} even and a function f : { 1 , … , n } → { 1 , … , n } {\displaystyle f:\,\{1,\ldots ,n\}\rightarrow \{1 ...
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.
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.
Buffon died only three months after the moose's arrival, and his theory of New World degeneration remained forever preserved in the pages of the Histoire Naturelle. [10] In the years following Buffon's death, the theory of degeneration gained a number of new followers, many of whom were concentrated in German-speaking lands.
