We did something similar in chemistry today, so i just had to come back and comment this! Difference is we had to see if certain chemicals were effected by the charge, proving if they were polar or non-polar based on the position of their atoms. So in a way this can be chemistry aswell as physics as there're several areas where physics and chemistry are similar, one of which is atomic structure :P
Made me think, and i worked out the average human only takes up something like 1 25,250,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000th of the universe (after rounding). Then again i've only just started my AS level in maths so dont trust that too much :P
I did not see that one coming... just as I was reaching for the back button thinking there was no punchline... BAM! NEDM to the face! anyway... I lol'd
