Time travel?

A good article about the possible implications of the neutrino experiment.  Some good links too, but ignore the dodgy google ads, especially if they use the word quantum...

Half term homework

Just a reminder that there is HW set on Kerboodle.  In addition to this, watch "Faster than the speed of light", still available on bbciplayer.
Happy holidays!

Year 12 homework - conservation rules

 

What is the  equation for neutron decay?

Calculate the charges and mass-energies of all particles involved.  Is it possible?

What happens to the energy left over?

Check the equations in q3 P480 – could they happen? Is mass-energy and charge conserved? (Use table on P493 to help)

•Interactions between particles must obey three basic conservation rules

•Momentum conservation

•Mass-energy conservation

•Charge conservation
