The field of Elementary Particle Physics has developed in
a natural progression since the turn of the last century
This is an attempt to provide the historical context and
examples of the experiments
What is Particle Physics?
We aim to answer the following questions:
What are the elementary constituents of matter?
What are the fundamental forces that control their behavior at
the most basic level?
