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.
The EVATAR is a working model of a reproductive system made from a mouse ovary and bits of a human uterus, cervix, vagina, fallopian tubes, and liver. Developed by Northwestern University researcher Teresa Woodruff and her colleagues, the EVATAR is intended to help better test the effects of medicines and toxins on women. And now […]
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
What could be more fun than a slingshot that shoots tiny airplanes? A slingshot that shoots tiny glowing airplanes of course! These toy planes are outfitted with ultra-bright LEDs, so you can fly all night without losing them in the trees.Whether you are a regular-sized child, or an overgrown adult one, these light-up flyers offer […]
