Source: WordNetI think also of my colleagues in elementary particle theory in many lands, and feel that in some measure I am here as a representative of our small, informal, international fraternity. Murray Gell-Mann
So far Unitarian realism claiming to possess positive knowledge about Ultimate Reality has succeeded only by excluding large areas of phenomena or by declaring, without proof, that they could be reduced to basic theory, which, in this connection, means elementary particle physics. Paul Karl Feyerabend
String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string. Edward Witten
It's indeed surprising that replacing the elementary particle with a string leads to such a big change in things. I'm tempted to say that it has to do with the fuzziness it introduces. Edward Witten
Experts have a vested interest in their own playpens, and so they will quite naturally argue that 'education' is impossible without them (can you imagine an Oxford philosopher, or an elementary particle physicist arguing himself out of good money?) Paul Karl Feyerabend
They have the lowest known mass of any elementary particle, are electrically neutral, and only interact weakly with other matter. Source: Internet
