  2. Speed of electricity - Wikipedia

    en.wikipedia.org/wiki/Speed_of_electricity

    The speed of this flow has multiple meanings. In everyday electrical and electronic devices, the signals travel as electromagnetic waves typically at 50%–99% of the speed of light in vacuum. The electrons themselves move much more slowly. See drift velocity and electron mobility.

  3. Tumbler screening technique - Wikipedia

    en.wikipedia.org/wiki/Tumbler_screening_technique

    Tumbler screening is a separation method that uses three-dimensional elliptical movement to separate very fine particles from larger ones.. Tumbler screening is a mechanical screening technique used in many fields that deal with raw materials and building materials for process and reuse. [1]

    [23] [24] One consequence is that c is the speed at which all massless particles and waves, including light, must travel in vacuum. [25] [Note 7] The Lorentz factor γ as a function of velocity. It starts at 1 and approaches infinity as v approaches c. Special relativity has many counterintuitive and experimentally verified implications. [27]

  5. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    Simple illustration of particles in the solid state – they are closely packed to each other. In a solid, constituent particles (ions, atoms, or molecules) are closely packed together. The forces between particles are so strong that the particles cannot move freely but can only vibrate. As a result, a solid has a stable, definite shape, and a ...

  6. Indistinguishable particles - Wikipedia

    en.wikipedia.org/wiki/Indistinguishable_particles

    For two indistinguishable particles, a state before the particle exchange must be physically equivalent to the state after the exchange, so these two states differ at most by a complex phase factor. This fact suggests that a state for two indistinguishable (and non-interacting) particles is given by following two possibilities: [2] [3] [4]

  7. Generation (particle physics) - Wikipedia

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

    Between generations, particles differ by their flavour quantum number and mass, but their electric and strong interactions are identical. There are three generations according to the Standard Model of particle physics. Each generation contains two types of leptons and two types of quarks.

    For humans, we're 99.9 percent similar to the person sitting next to us. The rest of those genes tell us everything from our eye color to if we're predisposed to certain diseases.

  9. Higgs boson - Wikipedia

    en.wikipedia.org/wiki/Higgs_boson

    The Higgs boson, sometimes called the Higgs particle, [9] [10] is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, [11] [12] one of the fields in particle physics theory. [12]
