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.
It’s been years since the major pharma companies agreed to participate in the Registry of All Trials, meaning that they’d end the practice of only reporting on trials whose outcomes they were pleased with, leaving about half of all trials unreported-on.
Archaeologists excavating a Hittite city on the border of Turkey and Syria found a broken jug that, upon restoration, revealed a smiley face. At 3,700-years-old, it could be the oldest smiley face drawing ever found. From Smithsonian: According to Zuhal Uzundere Kocalar at Turkey’s state-run news service, the Anadolu Agency, the researchers did not notice […]
On August 3 in celebration of the 40th anniversary month of the Voyager interstellar mission, please join me at San Francisco’s Exploratorium to experience the Voyager Golden Record with two of the brilliant minds behind it — SETI pioneer Frank Drake and science writer Timothy Ferris. In August and September 1977, NASA launched two spacecraft, […]
