Fundamentals of Physics

Understanding Physical Reality
Understanding Physical Reality
Physics is the study of matter, energy, and the fundamental forces of nature. It explains phenomena from the subatomic to the cosmic scale, underpinning all other sciences.
Classical Mechanics Foundations
Classical Mechanics Foundations
Newton's Laws of Motion form the basis of classical mechanics, describing how objects move under various forces. They revolutionized our understanding, setting the stage for modern engineering.
Thermodynamics and Heat Transfer
Thermodynamics and Heat Transfer
Thermodynamics involves heat, work, and temperature, governing energy transfer. Did you know the coldest possible temperature, absolute zero (-273.15°C), is theoretically unattainable due to the third law of thermodynamics?
Electromagnetism's Invisible Forces
Electromagnetism's Invisible Forces
Electromagnetism is a branch of physics that deals with the electromagnetic force that occurs between electrically charged particles. It's responsible for practically all phenomena encountered in daily life, barring gravity.
Quantum Mechanics Mysteries
Quantum Mechanics Mysteries
Quantum mechanics challenges classical physics, showing particles also have wave-like properties. The Heisenberg Uncertainty Principle states you cannot simultaneously know the position and velocity of a particle.
Relativity: Space-Time Continuum
Relativity: Space-Time Continuum
Einstein's Theory of Relativity consists of Special and General Relativity, which describe the relationship between space, time, and gravity. GPS systems must account for these effects to maintain accuracy.
Unification and Theories of Everything
Unification and Theories of Everything
Physicists are working to unify the fundamental forces of nature into a single framework. String theory and loop quantum gravity are leading candidates, but still largely theoretical.
Speed of Darkness
Speed of Darkness
Dark matter moves slower than light, yet constitutes about 27% of the universe’s mass-energy content. Its nature remains one of physics' greatest unsolved mysteries.
