Nine and nano both start with n - that should help you remember ;)

Hi Everyone! :D

I have a practical assessment task for Physics soon (finding slit separation distance) and there is a part that wants us to look at "Experiment Analysis", does this just essentially mean answering questions on, Reliability, Validity and Accuracy of the experiment or something else?

Thanks in advance!

Hi,
I don’t do physics but I think it means analysing your results and coming to a conclusion based on that and interpretation of the results and explain what the results mean,  reliability and how reliable it was, improvements that can be made to the experiment, whether the results were consistent with expectations and did or did not support the hypothesis

Can someone please explain if inflation came before or after annihilation? I thought it was annihilation first because inflation separates the matter from anti-matter and stopping lonely particles from annihilating but I’m not sure. I've heard mixed statements so I would appreciate it if you could give reasoning behind your answer.

Thanks!
