Brain Cox works on the Large Hadron Collider that's about to become operational at CERN.
Aim of particle physics is to find out what everything is made of. As you get back to the early times of the universe, things were simpler. In the 1st billionth of a second it was very simple. Everything was made from 12 particles of matter stuck together by four forces. "All science is either physics or stamp collecting." - Ernest Rutherford
Large Hadron collider is 27 Km in circumference and will accelerates protons to 99.99999% the speed of light (I might not have gotten the right number of 9s, sorry if this spoils your calculations if you are trying this at home). These will collide with another beam of protons going in the opposite direction.
Higgs gives mass to fundamental particles. Particles are massive because they are surrounded by Higgs particles. (Maggie Thatcher shown here surround by a Higgs field). The LHC will hopefully verify the existence of Higgs particles. If not, it'll find whatever is responsible for giving mass to stuff.
What particle physics means to me: gives modern science a creation story. We know universe beAgn 13.7 billion years ago as a dot smaller than an atom. Universe underwent exponential expansion in a billionth of a second and continues to expand. AFter 400 million years, the first stars formed and other elements were cooked in them. On some planets oxygen and hydrogen formed into water, liquid water on some planets. On at least one planet, life formed.

University of Zurich researchers used transcranial magnetic stimulation, a noninvasive method of inhibiting activity in parts of the brain, to “turn off” people’s ability to control their impulses. They focused on the temporoparietal junction, an area of the brain thought to play an important role in moral decisions, empathy, and other social interactions. They hope […]
