Introduction to Physics

Physics

• Physics is the natural science that involves the study of matter, its motion and behavior through space and time, and related concepts such as energy and force.
• Key branches include:
  • Classical mechanics: Studies motion of macroscopic objects, including Newton's laws of motion and gravitation.
  • Thermodynamics: Deals with heat, temperature, and their relationship to energy and work.
  • Electromagnetism: Explores the behavior of electric and magnetic fields and their interaction.
  • Optics: Focuses on the behavior of light and its interaction with matter.
  • Modern physics: Includes relativity, quantum mechanics, and nuclear physics.
• Fundamental quantities: Length, mass, time, electric current, temperature, amount of substance, and luminous intensity.
• Fundamental forces: Gravitational, electromagnetic, strong nuclear, and weak nuclear.
• Key concepts: Energy, momentum, angular momentum, conservation laws, fields, waves, and oscillations.

Biology

• Biology is the scientific study of life and living organisms.
• Key branches include:
  • Botany: The study of plants
  • Zoology: The study of animals
  • Microbiology: The study of microorganisms
  • Ecology: The study of the interactions between organisms and their environment.
  • Genetics: The study of heredity and variability.
  • Cell biology: The study of cells, their structure, function, and organization.
  • Molecular biology: The study of biological molecules and their interactions.
• Key concepts: Cells, genetics, evolution, ecosystems, biodiversity, and the scientific method.
• Levels of biological organization: From atoms to molecules to organelles to cells to tissues to organs to organ systems, to organisms, populations, communities, and biosphere.

Chemistry

• Chemistry is the science that deals with the composition, properties, and transformations of matter.
• Key branches include:
  • Organic chemistry: Study of carbon-containing compounds
  • Inorganic chemistry: Study of non-carbon and organometallic compounds
  • Physical chemistry: Study of the physical principles governing chemical processes
  • Analytical chemistry: Study of the methods for identifying and quantifying matter
• Key concepts: Atoms, molecules, chemical bonds, chemical reactions, stoichiometry, solutions, acids and bases, equilibrium, thermodynamics, kinetics.
• States of matter: Solids, liquids, gases, and plasma.
• Periodic table: Organization of elements based on their properties.
• Chemical formulas and equations: Representation of substances and reactions.

Mathematics

• Mathematics is the study of quantity, structure, space, and change.
• Key branches include:
  • Arithmetic: Basic operations with numbers
  • Algebra: Study of symbols and their manipulation
  • Geometry: Study of shapes and their properties
  • Calculus: Study of continuous change
  • Statistics: Study of data collection, analysis, and interpretation
  • Probability: Study of the likelihood of events
• Key concepts: Numbers, equations, functions, graphs, theorems, proofs, reasoning, logic.
• Applications of mathematics extend to various fields, like physics, engineering, finance, computer science and more.
