71Massless particle — In particle physics, a massless particle is a particle whose invariant mass is zero. Currently, the only known massless particles are gauge bosons: the photon (carrier of electromagnetism) and the gluon (carrier of the strong force). However,… …
72Drude particle — Drude particles are model oscillators used to simulate the effects of electronic polarizability in the context of a classical molecular mechanics force field. It is based on the Drude model of mobile electrons. Molecular mechanics models,… …
73Minimum Ionizing Particle — In physics, a minimum ionizing particle (or mip) is a particle whose mean energy loss rate through matter is close to the minimum.When a fast charged particle passes through matter, it ionizes or excites the atoms or molecules that it encounters …
74Planck particle — A Planck particle is a hypothetical subatomic particle, defined as a tiny black hole whose Compton wavelength is the same as its Schwarzschild radius. Its mass is thus (by definition) equal to the Planck mass, and its Compton wavelength and… …

76interplanetary dust particle — ▪ astronomy also called micrometeoroid, micrometeorite , or cosmic dust particle a small grain, generally less than a few hundred micrometres in size and composed of silicate minerals and glassy nodules but sometimes including sulfides,… …
77Signal recognition particle RNA — The signal recognition particle RNA is an RNA molecule that is a component of the signal recognition particle (SRP). 7SL RNA In eukaryotes, the SRP RNA is known as 7SL RNA Although originally the SRP was thought to be only composed by 6… …
78Large Hadron Collider-The World's Most Powerful Particle Accelerator — ▪ 2009 On Sept. 10, 2008, scientists of the European Organization for Nuclear Research ( CERN), Geneva, ran the first test operation of what had been described as the largest machine and the most ambitious scientific experiment ever built… …
