- Finding the God Equation | Podcasts | Naked Scientists
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
- QotW: Can transfusions change your blood type?
Emma - Hmmm… interesting question We put it to our forum Polly didn’t think it was possible, Chris and Evan said you need a bone marrow transplant to change your blood type So we asked Dr Cedric Ghevaert from the University of Cambridge Cedric - Our blood cells are divided into red cells, white cells and platelets All our blood cells carry an identity card on their surface made out of
- Seeing Red | Science Features - The Naked Scientists
A tiny string vibrating in a different pattern would have the requisite properties to identify it as a quark, a neutrino, or any other kind of particle Thus String Theory claims that the vibrating string is an electron because it has all the properties of an electron
- Why do doctors remove air from syringes? | Science Questions
When you are given an injection why is the doctor or nurse very careful to make sure there is no air in the barrel of the syringe? Because when you cut yourself it doesn’t matter, there’s air all around the wound
