These would include particles such as the constituents of atoms – protons, neutrons, and electrons – as well as other types of particles which can only be produced in particle accelerators or cosmic rays.

Jan 25, 2026 · Particle physics is concerned with structure and forces at this level of existence and below. Fundamental particles possess properties such as electric charge, spin, mass, magnetism, …

What is a particle? Classically, particles & waves are 2 different things. A classical particle is a point-like object. The type of particle is defined by properties that define how it interacts: mass (gravity) & …

Jun 26, 2025 · In the realm of physics, the term ‘particle’ is far more nuanced than the everyday connotation of a tiny, indivisible object. It represents a fundamental concept in our understanding of …

May 26, 2025 · Particle physics describes the universe at the smallest scale. This includes subatomic particles, like protons and neutrons, as well as elementary particles, like quarks and electrons, which...

The theory describes two fundamental types of particles: fermions, which makes up all of the ‘stuff’ around us, and bosons, which mediate how fermions interact with one another.

Mar 26, 2025 · Elementary particle physics is the study of fundamental particles and their interactions in nature. Those who study elementary particle physics—the particle physicists—differ from other …

Aug 29, 2024 · Particles can be atoms, molecules, or subatomic particles like protons, neutrons, and electrons. These tiny units are the building blocks of all substances, both living and non-living. Atoms …

Nov 12, 2020 · Given that everything in the universe reduces to particles, a question presents itself: What are particles? The easy answer quickly shows itself to be unsatisfying. Namely, electrons, …

What is Particulate Matter? Airborne particulate matter (PM) is not a single pollutant, but rather is a mixture of many chemical species. It is a complex mixture of solids and aerosols composed of small …
