Baryon

Baryon

A particle that is made of 3 quarks each of a different color. For example, a proton is a baryon which is made of 2 up quarks and a down quark.

Biofuel

Biofuel

Fuel derived from living or recently living organisms. Examples include biodiesel made from oils or fats, and bioethanol made from the fermented sugar components of plant materials.

Biomass

Biomass

Living matter that is used as a source of renewable energy. Examples include wood, gasses, garbage, and alcohol fuels.

Boson

All fundamental particles can be classified as either bosons or fermions. Particles have lots of different properties, such as electric charge and spin. Bosons are particles that can group together even if they have exactly identical properties. Force carrier particles, like photons and gluons, are bosons. Fermions are particles that cannot exist together if they have identical properties. click to enlarge image.

One of the six types (flavors) of quarks. It is the most massive of the quarks which have negative electric charge. Deena is shown here as a bottom quark.
