  1. The idea of quantum field theory began in the late 1920s with British physicist Paul Dirac, when he attempted to quantize the energy of the electromagnetic field; just like in quantum mechanics the energy of an electron in the hydrogen atom was quantized. Quantization is a procedure for constructing a quantum theory starting from a classical ...

  2. Given these distinctions within the field of physics (experimental and theoretical, classical and modern) it is useful to further subdivide physics into various disciplines, including astrophysics, atomic and molecular physics, biophysics, solid state physics, optical and laser physics, fluid and plasma physics, nuclear physics, and particle ...

  3. Sep 13, 2022 · Unfortunately, the general theory of relativity (GR) – which describes how gravity and space–time work in our universe – is not compatible with quantum mechanics. Indeed, GR says that space–time is continuous, whereas quantum mechanics dictates that everything is in discrete quantized packets of matter and energy.

  4. Feb 18, 2013 · Following Plato's theory of forms, the most objective reality is represented by idealized, non-physical forms or ideas. The relationship between physical objects and these forms is what gives them ...

  5. Jun 08, 2022 · “If one asks what… is characteristic of the world of ideas of physics, one is first of all struck by the following: the concepts of physics relate to a real outside world… it is a further ...

  6. The paper "Unified Field Theory and the Configuration of Particles" opened a new chapter of physics. One of the predictions of the paper is that a proton has an octahedron shape. As Physics progresses, it focuses more on invisible particles and the unreachable grand universe as visible matter is studied theoretically and experimentally.

  7. Karl Popper: Philosophy of Science. Karl Popper (1902-1994) was one of the most influential philosophers of science of the 20th century. He made significant contributions to debates concerning general scientific methodology and theory choice, the demarcation of science from non-science, the nature of probability and quantum mechanics, and the methodology of the social sciences.
