High-energy collisions have led to the observation of many hundreds of new hadronic particle states. These new particles, which are generally unstable, appear to be just as fundamental as the neutron and the proton.

- Carlo Rubbia

I started out working on supersymmetry. The theory predicts that for every particle we know about, there will be an additional particle.

- Lisa Randall

I do not keep up with the details of particle physics.

- Murray Gell-Mann

I have a theory that evolutionary biologists are more vain than particle physicists.
