A particle is a small object. These come in many different types. Some are too small to see. Some can be seen with microscopes, others are too small even for microscopes. All large objects are made of smaller objects. Everything in the universe is ultimately composed of very small, sub-microscopic particles.
The big idea of particles is: Proliferation of Dualities - particle and wave; particle and field;discrete and continuous; objective reality and anthropic idea; math. description and interpretation atc.
The idea of particles being in constant random motion is known as Brownian motion. This concept explains the seemingly random movement of particles in a fluid, which is caused by the collisions of the fluid molecules with the particles. This motion was first observed by the Scottish botanist Robert Brown in 1827.

atoms
Coining of the term "atom" and the idea that matter was composed of small, invisible, indivisible particles.
The statement "Matter is composed of tiny particles that are constantly in motion" best supports the idea that matter is made up of particles. This concept is fundamental to the particle theory of matter, which explains that all substances, regardless of their state (solid, liquid, or gas), consist of small, discrete units. Observations such as the behavior of gases and the diffusion of substances further reinforce this idea, illustrating how these particles interact and move.
I have no idea I was kind of looking for the answer
Particle theory, as opposed to string theory.
Matter is composed from small particles called atoms.
Compound theory
no idea can someone tell me
The idea of atomic structure of the world was proposed intuitively by Leukippus and Democritus 2 500 years ago.
