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!
