particles

1. particles are a small localised object or entity to which can be ascribed several physical or chemical properties such as volume, density or mass

   • did you know that they're many different types of particles with different particle sizes and properties?
     • types of particles include, atoms, molecules and fermions
       • light is also made of particles called photons. most of the time these aren't noticeable but astronauts report seeing flashes of lights even with their eyes closed. this is caused by a single photons moving through the fluid inside the eyeball
         • everything in the universe from stars and plants to us and the chairs we sit on is made from the same basic building blocks/ particles of matter. particle physics studies these very small building block particles and works out how they interact to make the universe look and behave the way it does
           • a particle is a small portion of matter, the word includes an enormous range of sizes from subatomic particles such as an electrons through to particles of dust floating in the sunlight
