The nature of elementary particles

MAR 01, 1976
Because particle number is not conserved in high‐energy interactions it may be meaningless to ask about the constituent parts of elementary particles; perhaps the central problem is dynamics.
Werner Heisenberg

The question, “What is an elementary particle?” must find its answer primarily in experiment, although it must also be confronted with philosphical considerations. I will therefore begin by giving a short survey of the important experimental results of the last fifty years. This survey will show that a critical unbiased study of these results already gives an answer to the question; theory, as we shall see, cannot add much to this answer.
