    Study Notes

    Classical Physics

    • Classical physics encompasses branches established before the 20th century, including mechanics, acoustics, optics, thermodynamics, and electromagnetism.
    • Classical mechanics deals with forces acting on bodies and can be divided into statics, kinematics, and dynamics.
    • Mechanics is further split into solid mechanics and fluid mechanics, which includes hydrostatics, hydrodynamics, aerodynamics, and pneumatics.
    • Theories in classical physics, like Newton's laws, serve as frameworks for other fields and are foundational concepts for all physicists.

    Theories and Research

    • Classical mechanics is effective for objects larger than atoms and moving slowly relative to the speed of light.
    • Chaos theory emerged in the 20th century as a subset of classical mechanics.
    • Physics continues to evolve, with various specialized areas still actively researched, including quantum mechanics and thermodynamics.

    Scientific Method

    • Scientific theories in physics are tested using the scientific method for validity through experimental comparison.
    • Scientific laws are succinct statements reflecting fundamental principles, such as Newton's law of universal gravitation.

    Major Fields of Physics

    • Nuclear and Particle Physics

      • Studies interactions of matter and energy at a fundamental level; includes the Standard Model.
      • Focus on the behavior of subatomic particles (quarks, leptons) and forces (strong, weak, electromagnetic).
      • Significant milestone: discovery of the Higgs boson at CERN in 2012.
    • Atomic, Molecular, and Optical Physics (AMO)

      • Examines matter and light interactions at atomic and molecular levels.
      • Each area employs classical, semi-classical, and quantum methods to analyze behavior on a microscopic scale.
    • Condensed Matter Physics

      • Originated from solid-state physics, addressing properties of solids and fluids, including phases and quantum effects.
      • Key concepts include Bose-Einstein condensate and superconductivity.
    • Astrophysics

      • Applies physics theories to understand stars, galaxies, the cosmos, and the universe's formation.
      • Integrates multiple domains of physics, including thermodynamics and relativistic theories.
      • Significant advancements through radio astronomy and space exploration.

    Applications of Physics

    • An understanding of physics is critical in various fields, enhancing aerospace technology, video game realism, and forensic science.
    • Simulation models allow predictions about Earth's past and future, critical for technological developments.
    • Interdisciplinary fields like econophysics and sociophysics show the breadth of physics applications across other domains.
