Study Notes
Natural Science
- Encompasses the study of the natural and biological world.
- Divided into biological sciences (e.g., botany, ecology, biochemistry, zoology) and physical sciences (e.g., chemistry, astronomy, physics).
- The objective of studying physical science is to gain knowledge of the non-living parts of Earth and the universe, enabling effective control and utilization of natural phenomena, emphasizing resource conservation, and appreciating scientific discoveries and inventions.
Physics
- Derived from the Greek word "fusis," meaning nature.
- The most fundamental branch of science, dealing with the structure of matter and interactions between fundamental constituents of the universe.
- Expressed using mathematical language, studying the laws governing the universe’s structure, forces between objects, and the matter-energy interrelationship.
Divisions of Physics
- Classical Physics: Includes Newtonian mechanics (mechanical physics/mechanics), electromagnetism, acoustics, thermodynamics, optics, geophysics, and biophysics.
- Modern Physics: Includes cryophysics (low-temperature physics), quantum physics, solid-state physics (condensed-matter physics), atomic and nuclear physics, and plasma physics.
Branches of Classical Physics
- Mechanical Physics/Mechanics: Studies the motion and behavior of objects under various forces, encompassing concepts like force, matter, and motion.
- Electromagnetism: Studies magnetic forces and fields created by moving electrical charges and vice versa.
- Acoustics: Studies the production and properties of sound waves and their transmission through different mediums.
- Thermodynamics: Studies heat, other energy forms, and energy conversions.
- Optics: Studies light behavior and its interactions with objects.
- Geophysics: Studies the physical processes and properties of Earth and its surrounding space environment.
- Plasma Physics: Studies the fourth state of matter, plasma, and its properties.
- Nuclear Physics: Studies atomic nuclei, forces within, and nuclear reactions.
- Astrophysics: Applies physics and chemistry to celestial objects like stars, planets, and galaxies.
- Biophysics: Applies physical principles and methods to biological problems, including bioelectricity.
- Psychophysics: Studies physical stimuli and their interaction with sensory systems.
- Food Physics: Deals with the physical properties of food and its ingredients.
Branches of Modern Physics
- Cryophysics: Studies phenomena at extremely low temperatures, near absolute zero.
- Quantum Physics: Based on quantum theory, dealing with matter, electromagnetic radiation, and their interactions.
- Solid-State Physics: Studies the physical properties of solid materials.
- Atomic and Nuclear Physics: Studies atomic nuclei and nuclear reactions.
- Plasma Physics: Studies highly ionized gases.
Key Figures in Physics
- Isaac Newton (1643-1727): Known for his three laws of motion.
- Albert Einstein (1879-1955): Known for Brownian motion and the photoelectric effect.
- James Clerk Maxwell (1831-1879): Known for the kinetic theory of gases.
- Wolfgang Pauli (1900-1958): Known for the exclusion principle.
- Paul Dirac (1902-1984): Helped found quantum electrodynamics.
- James Prescott Joule (1818-1889): Known for the mechanical equivalent of heat.
Key Terms
- Applied Physics: Applying physics to solve human problems.
- Matter: Anything with mass and occupying space.
- Energy: Capacity to do work or cause change.
- Work: Energy transfer when a force acts over a distance.
- Distance: Space between two points.
- Force: Push or pull that can change an object's motion.
- Motion: Change in an object's position over time.
