13b work for Ms Hamnett Tuesday P1 (no lesson)

Dear Y13
In addition to the list of work on the earlier blog post, work for Tuesday P1 is as follows
Research an experimental method of finding the specific charge on the electron.  This needs to have a diagram, an explanation and full details of the calculations that would need to be done.  Come on Friday ready to explain this method to the rest of the class.
Thanks and see you Friday
Ms Hamnett

Graviational waves discovered with an interferometer!

Einstein's gravitational waves 'seen' from black holes

For the first time, scientists have detected tiny, rhythmic distortions in space and time - gravitational waves - predicted by Einstein 100 years ago.
