The first 7N/8S piece of holiday work

Those 7N students who are destined for 8S have the opportunity to do a little science investigation or research this holiday. I have encouraged them to find out about something in a theoretical or practical way and here is the first piece that has arrived in my inbox.

The Quark
The quark not to be confused with the dairy product quark but the quark is an elementary particle. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons. Quarks can never be found directly in isolation they can be found only within hadrons, such as baryons and mesons. Quarks have various intrinsic properties including, electrical charge, mass, colour change and spin. Quarks are the only elementary particles in the standard model of particle physics to experience all four fundamentals interactions which are electromagnetism, gravitation, strong interaction, weak interaction. There are six types of quarks, up, down, strange, charm, top and bottom. Up and down quarks have the lowest masses of all the quarks, for every quark there is a corresponding antiparticle, known as an antiquark. The quark model was proposed by physicists Murray Gell – Mann and George Zweig. 

By Zuhayr


An interesting piece from Zuhayr, it certainly helps us to understand more about the particles that the LHC in Cern is flinging around in massive circles and then crashing into other things. Interestingly I had never heard of the dairy quark but googled it and found out all about the "naturally fat free and a brilliantly versatile dairy ingredient that's great for cooking, mixing and baking."
