(1) The fundamental particles of which matter is made are arranged in generations.

(2) Each family contains four siblings: two fundamental particles known as quarks and two known as leptons.

(3) Quarks are thought to be the fundamental particles from which matter, such as protons, is built.

(4) The positive energy develops into fundamental particle, and the negative energy develops into negative energy field.

(5) They propose that each so-called fundamental particle actually contains a tiny, vibrating, one-dimensional loop of string.

(6) The fundamental particle is the very fine clay particle composed of single crystal, and is the basic unit of mixed layer clays formed by one or several kinds of silicates with the sheet structure.

(7) It is doubtless true that at bottom the behaviour of a motor car is to be explained in terms of interactions between fundamental particles.

(8) In the same way that matter is constituted of fundamental particles, antiparticles are the building blocks of antimatter.

(9) The boundaries of physics constantly change as new discoveries are made, e.g. the discovery of new fundamental particles.

(10) Their layered form increases the photocell's efficiency in capturing photons, the fundamental particles of which light is made.

(11) It's a lot like a regular quark, only heavier, meaning it's composed of an even more fundamental particle the standard model doesn't account for.

(12) Gleick: Modern physics has begun to think of the bit—this binary choice—as the ultimate fundamental particle.

(13) This is one of the few examples of a fundamental particle being predicted in theory and later discovered by experiment.
