2. Wave–particle duality - Wikipedia

   en.wikipedia.org/wiki/Wave–particle_duality

   The electron double slit experiment is a textbook demonstration of wave-particle duality. [2] A modern version of the experiment is shown schematically in the figure below. Left half: schematic setup for electron double-slit experiment with masking; inset micrographs of slits and mask; Right half: results for slit 1, slit 2 and both slits open ...

3. Newton's laws of motion - Wikipedia

   en.wikipedia.org/wiki/Newton's_laws_of_motion

   Newton's laws are often stated in terms of point or particle masses, that is, bodies whose volume is negligible. This is a reasonable approximation for real bodies when the motion of internal parts can be neglected, and when the separation between bodies is much larger than the size of each.

4. Matter wave - Wikipedia

   en.wikipedia.org/wiki/Matter_wave

   Matter waves are a central part of the theory of quantum mechanics, being half of wave–particle duality. At all scales where measurements have been practical, matter exhibits wave -like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave.

5. Double-slit experiment - Wikipedia

   en.wikipedia.org/wiki/Double-slit_experiment

   A well-known thought experiment predicts that if particle detectors are positioned at the slits, showing through which slit a photon goes, the interference pattern will disappear. [9] This which-way experiment illustrates the complementarity principle that photons can behave as either particles or waves, but cannot be observed as both at the ...

6. Generation (particle physics) - Wikipedia

   en.wikipedia.org/wiki/Generation_(particle_physics)

   The second and third generations of charged particles do not occur in normal matter and are only seen in extremely high-energy environments such as cosmic rays or particle accelerators. The term generation was first introduced by Haim Harari in Les Houches Summer School, 1976. [2] [3]

7. Particle physics - Wikipedia

   en.wikipedia.org/wiki/Particle_physics

   A third major effort in theoretical particle physics is string theory. String theorists attempt to construct a unified description of quantum mechanics and general relativity by building a theory based on small strings, and branes rather than particles. If the theory is successful, it may be considered a "Theory of Everything", or "TOE". [50]

8. List of states of matter - Wikipedia

   en.wikipedia.org/wiki/List_of_states_of_matter

   Strange matter: A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed. Quark matter: Hypothetical phases of matter whose degrees of freedom include quarks and gluons Color-glass condensate

9. Standard Model - Wikipedia

   en.wikipedia.org/wiki/Standard_Model

   Elementary-particle masses and the differences between electromagnetism (mediated by the photon) and the weak force (mediated by the W and Z bosons) are critical to many aspects of the structure of microscopic (and hence macroscopic) matter. In electroweak theory, the Higgs boson generates the masses of the leptons (electron, muon, and tau) and ...
