"In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time."
Study of the physical laws that describe the behavior of particles moving at high speeds.
Lorentz transformations: A mathematical formula that describes how physical measurements of space and time change when an observer is moving relative to the event being measured.
Time dilation: The concept that time appears to slow down for an observer moving relative to another observer.
Length contraction: The concept that objects appear to shrink in the direction of motion for an observer moving relative to another observer.
Relativistic momentum: A measure of the motion of a particle taking into account its mass, velocity, and Lorentz factor.
Energy-momentum relation: The relationship between the energy and momentum of a particle, including the relativistic effects of mass and velocity.
Particle collisions: Interactions between particles that involve the transfer of energy, momentum, and/or mass.
Particle decay: The process by which unstable particles transform into more stable particles, often involving the emission of particles.
Mass-energy equivalence: The idea that mass and energy are different forms of the same thing, as described in Einstein's famous equation E=mc^2.
Relativistic mechanics: The application of relativistic principles to the study of the motion of particles and bodies.
Special relativity: Einstein's theory of relativity, which describes the behavior of objects moving at high speeds and in the absence of gravitational fields.
General relativity: Einstein's theory of relativity, which includes the effects of gravity on the motion of objects and the geometry of spacetime.
Quantum electrodynamics: The theory that describes the behavior of charged particles and electromagnetic interactions at the quantum level.
Quantum field theory: A framework for describing particles and their interactions based on fields that permeate all of space and time.
Standard Model of particle physics: A theoretical framework that describes the behavior of subatomic particles and their interactions.
Lorentz transformations: The Lorentz transformations are a set of equations that describe how measurements of space and time by one observer are transformed when seen by another observer who is moving at a constant velocity relative to the first observer. These transformations are essential to understanding relativistic kinematics.
Time dilation: Time dilation is a phenomenon that arises due to the relativistic effect of time being affected by velocity. This phenomenon results in an observer observing time running slower in a system that is moving relative to them.
Length contraction: Length contraction describes the reduction in the length of an object as observed by a moving observer, due to the relativistic effect of space being affected by velocity. This contraction is proportional to the relative velocity between the observer and the object.
Relativistic mass: Relativistic mass is the mass of a particle when it is moving at a high velocity relative to a stationary observer. As the velocity increases, the mass of the particle increases, approaching infinity as the velocity approaches the speed of light.
Momentum: Relativistic momentum is a product of the mass and velocity of a particle, taking into account the relativistic effect of mass on velocity.
Energy: Relativistic energy is a combination of kinetic energy and rest mass energy, taking into account the relativistic effect of mass on energy. This energy increases as the velocity of the particle increases, approaching infinity as the particle approaches the speed of light.
Kinematics of decay: The kinematics of decay is the study of the properties of the products of a particle decay, including their momentum and energy.
Pair production and annihilation: Pair production is the creation of a particle-antiparticle pair from a high-energy photon, while annihilation describes the process in which a particle and antiparticle collide, resulting in their mutual destruction and the creation of gamma rays.
Scattering: Scattering is the process in which a particle collides with another particle or system, resulting in a change in direction and/or velocity of the particle.
Cross-sections: Cross-sections describe the probability of a particular scattering process occurring, taking into account the properties of the particles and their interactions.
Particle creation and annihilation in a strong electric field: Under the influence of a strong electric field, particles can be created or destroyed via the production of virtual particles.
Relativistic Bremsstrahlung: Bremsstrahlung is electromagnetic radiation emitted by a charged particle when it is slowed down by another charged particle, and relativistic Bremsstrahlung takes into account the relativistic effects on the emission of this radiation.

"The laws of physics are invariant (identical) in all inertial frames of reference (that is, frames of reference with no acceleration)."
"The speed of light in vacuum is the same for all observers, regardless of the motion of the light source or observer."
