What is the symmetry? Four dimensional rotations in Lorentz space Now let's take a look at the quark model The quark model, which is a model for the inside of the proton, has three quirks If you rotate three quark among themselves, the equations remain the same It's symmetrical under something called SU (3)
- Tetraquarks: new configurations of subatomic particles discovered
Researchers using the Large Hadron Collider at CERN say they’ve recently discovered a new exotic form of subatomic particles called tetraquarks They exist for just fractions of a second, so they’re hard to spot and study But, luckily, University of Cambridge physicist Harry Cliff, is working on the experiment that discovered them, as he described to Chris Smith
- How do atoms make colours? | Questions | Naked Scientists
The biggest effect is actually what colour something absorbs Different colours of light have different energies The bluer the light, and light comes in blobs called photons, the more energy the photon has The electrons inside atoms can only have certain energies so they have what are called energy levels Maybe they can absorb a certain amount of energy or twice that amount
- Fossil Feathers in Colour - Planet Earth Online | Interviews
An international team led by Roy Wogelius from the University of Manchester has developed a new technique that reveals the colour, and even chemistry, of fossil birds – birds that are more than 100 million years old
- What are magnets made of? | Science Questions - The Naked Scientists
Magnets are very useful things: you can stick things to fridges with them and they're very important in things like hard disk drives in your computer You can even make levitating trains with them But how do you make a magnet? Inside a metal like iron there are lots of tiny little magnets [called dipoles]; to start off with, they're all pointing in different directions It's
