atoms
Particle theory, as opposed to string theory.
The idea of atomic structure of the world was proposed intuitively by Leukippus and Democritus 2 500 years ago.
John Dalton, an English school teacher and chemist, proposed the idea that everything is made of very small particles called atoms in the early 19th century. His atomic theory laid the foundation for modern chemistry.
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.
Matter is composed from small particles called atoms.
Yes he was. He became a teacher at the age of 12 so he was a teacher most of his life.
well,all good scientist persume so also if there were no particals that everything would be invisable i think
Coining of the term "atom" and the idea that matter was composed of small, invisible, indivisible particles.
you open the doors and windows and you clean everything. a vacuum is a good idea because contrary to sweeping you actually get rid of the dust and small particles whereas in sweeping you just move them around.
It is Democritus (440 B.C.) He proposed the idea that all atoms were small, hard particles made of one material and that everything can be broken down until there is nothing left but atoms. Course, this was long ago, so his theory wasn't exactly thorough enough..

Particles are microscopic and explain the properties of liquids, solids, and gases. The strength of the bonds between particles is different in each state. In digestion, the chunks of foods we eat must be broken down into particles to be used by the body.
