The philosophy of physics seeks to understand the fundamental nature of reality, exploring questions about the existence, structure, and properties of the physical world.

Materialism asserts that matter is the fundamental substance of reality and that all mental phenomena are epiphenomena of physical processes.

The Copenhagen Interpretation states that the wave function of a particle only provides a probabilistic description of its physical properties, meaning that it cannot be used to predict with certainty the outcome of a measurement.

The principle of special relativity states that the speed of light in a vacuum is the same for all observers, regardless of the motion of the light source or observer.

The Big Bang model is the prevailing cosmological model that describes the universe as expanding from a very hot, dense state approximately 13.8 billion years ago.

Wave-particle duality is a fundamental principle of quantum mechanics that states that particles can exhibit both wave-like and particle-like behavior, depending on the experimental setup.

General relativity states that the presence of mass or energy causes spacetime to curve, which in turn affects the motion of objects.

The Theory of Everything (TOE) is a hypothetical theory that aims to unify all the fundamental forces of nature into a single, comprehensive framework.

The principle of conservation of energy states that the total amount of energy in an isolated system remains constant, regardless of the changes that occur within the system.

The principle of conservation of momentum states that the total amount of momentum in an isolated system remains constant, regardless of the changes that occur within the system.

The principle of conservation of angular momentum states that the total amount of angular momentum in an isolated system remains constant, regardless of the changes that occur within the system.

The principle of relativity states that the laws of physics are the same for all observers, regardless of their motion.

The principle of quantization states that the energy of a system is quantized, meaning it can only exist in discrete values.

The principle of uncertainty states that the act of observing a quantum system affects the outcome of the measurement.

The principle of superposition states that quantum systems can exist in multiple states simultaneously until they are observed.
