    Atoms are the smallest neutral particles into which matter can be divided by chemical reactions. An atom consists of a small, heavy nucleus surrounded by a relatively large, light cloud of electrons.

    Even among particle physicists, the exact definition of a particle has diverse descriptions. These professional attempts at the definition of a particle include: [7] A particle is a collapsed wave function; A particle is a quantum excitation of a field; A particle is an irreducible representation of the Poincaré group; A particle is an ...

    en.wikipedia.org/wiki/History_of_subatomic_physics

    Throughout the 1950s and 1960s, improvements in particle accelerators and particle detectors led to a bewildering variety of particles found in high-energy experiments. The term elementary particle came to refer to dozens of particles, most of them unstable. It prompted Wolfgang Pauli's remark: "Had I foreseen this, I would have gone into botany".

    The smallest penguin species is the little blue penguin (Eudyptula minor), which stands around 30–33 cm (12–13 in) tall and weighs 1.2–1.3 kg (2.6–2.9 lb). [73] The smallest bird of prey is the Black-thighed falconet (Microhierax fringillarius), with a wingspan of 27–32 centimetres (11–13 in), roughly the size of a sparrow. [74]

    In this process, these small black holes radiate away matter. A rough picture of this is that pairs of virtual particles emerge from the vacuum near the event horizon, with one member of a pair being captured, and the other escaping the vicinity of the black hole. The net result is the black hole loses mass (due to conservation of energy).

  7. Particle - Wikipedia

    The smallest particles are the subatomic particles, which refer to particles smaller than atoms. [9] These would include particles such as the constituents of atoms – protons , neutrons , and electrons – as well as other types of particles which can only be produced in particle accelerators or cosmic rays .

  8. Elementary particle - Wikipedia

    en.wikipedia.org/wiki/Elementary_particle

    In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. [1] The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons .

    Guinness World Records certified the movie as The World's Smallest Stop-Motion Film ever made. [5] The film was accepted into the Tribeca Online Film Festival and shown at the New York Tech Meet-up and the World Science Festival. The film surpassed a million views in 24 hours, and two million views in 48 hours, with more than 27,000 likes.
