Anyone experienced with the experiments done with cooled supeconductors, can you explain the experiment with a little detail where they place a magnet over an already cooled superconductor? I have an explanation myself but theres alot of confliction between a couple people i know.
Could anyone give their thoughts on the possibility of the Plank Einstein debate on science's involvement in political affairs question coming up? Its such a burden to remember, even if its just key points.. In my opinion it has no physics involvement at all
The reason you ever divide by the number of groups factorial is because choosing
ABC DEF GHI
is the same as
DEF GHI ABC
therefore we get 3! more arrangements.
in the 2nd situation, there is an unequal number of people in each of the groups, therefore you dont need to divide by 3! as...
