Collision

Collision

(Science: physics) refers to the close approach of two or more particles, photons, atoms, nuclei, etc, during which such quantities as energy, momentum, and charge may be altered.

More-or-less synonymous with scattering, except in scattering one generally thinks of one of the particles as being at rest, and the other colliding particles scatter from their initial direction of motion due to the collision.

... to I stated Now stellar evolution tells us that accretion was the process that formed the Galaxies Stars and planets. The process consists of the collision of microscopic dust (the elements) and then sticking together. Let’s assume this is correct. So the hypothesis is that all these, rich in ...

... described interactions between NPTs and cellular components that tend to concentrate NTPs near a polymerase, increasing the rate of productive collision between NTPs and polymerase by increasing the local concentration of NTPs. However, none of these potential mechanisms need to pre-sort the ...
