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.
UC Berkeley’s Museum of Vertebrate Zoology employ a colony of flesh-eating beetles to clean the meat off the bones of animals whose bones they want to preserve for posterity. (KQED’s Deep Look)
Eliza writes, “A researcher from Lehigh University has invented a light-based pacemaker for fruit flies, and says a human version is ‘not impossible.’ The pacemaker relies on the new technique of ‘optogenetics,’ in which light-sensitive proteins are inserted into certain cells, allowing those cells to be activated by pulses of light. Here, the proteins were […]
San Francisco recently doubled the number of walls it was coating with hydrophobic paint, which is supposed to deter wall-pissing by making the urine spray back all over the pee-er.
Lean Project Management, as the name suggests, is a popular method for wasting less time and effort over the duration of a project. By focusing on prioritizing tasks, Project Managers are able to boost productivity, meet goals, and, inevitably, impress the execs. This exam prep course is led by the accredited Management and Strategy Institute, […]

Inspired by the universality of symbols, the founders of Noun Project began to collect thousands of hand-drawn icons. The concept has since transformed into a massive digital collection of 150,000+ unique icons that fuel the work of designers every day. Spend less time crafting icons and more time putting amazing designs out into the world with […]
