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.
Gravitational waves are real, and scientists have detected them. In the video above, PBS Space Time explains the discovery by researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO). From the New York Times: A team of physicists who can now count themselves as astronomers announced on Thursday that they had heard and recorded the sound […]
Evil Mad Scientist Labs have released their latest set of nerdy Valentines ready for you to print, glue on cardstock, and use to win your true love’s heart.
“Bentonite Me Baby” is a brand of “detox clay” that you spread on your face, or eat, to rid your body of mysterious, nonspecific “toxins.” It is full of lead.
If you’ve been blessed enough to avoid them yourself, you’ve definitely heard the horror stories. Late night, crushing out a ton of work, writing, coding, anything, then boom – your computer crashes. The battery blows, you spill water or coffee all over the place, or it just shuts down with no explanation, and you’re screwed. […]
You travel around a lot. It might be that jet set life from New York to LA to London to Tokyo, or it might be back and forth from the coffee shop to the office, or from the kitchen to the couch. Any which way, you’re mobile and that’s the way to live. When you […]
It’s 2016 and we like our technology really small. Our phones fit in our pockets, our remotes are lighter than ever, and even our cars seem to be shrinking. So your new drone shouldn’t be an exception. This Axis VIDIUS Drone is 21% off right now and it’s so little, your biggest problem won’t be […]
