I wouldn't sail this ship if I were you

Five fiendish physics problems

1. Consider a perfectly spherical cow of 1 metre diameter and uniform density. This cow needs milking. How are you going to do it?

2. I am pointing a 15 MW laser at the back of your head right now. No, don’t turn around. I’m not asking you to solve this problem, I’m just suggesting that you do have a problem here and asking you to acknowledge it. I probably won’t turn the laser on.

3. Derive Maxwell’s equations. To do this, you will need to use the fundamental constants pi and c. Note: both of these constants are hungry and one of them needs a wee. Your derivation will probably proceed much more smoothly if you can sort out their needs first.  

4. Consider two trains of mass m speeding towards each other. Train 1 is travelling at 50% of the speed of light, and train 2 at 20% of the speed of light. You are a passenger on train 2. Roughly how much energy will be released when they crash, and don’t you think you’d better find a way to get off before answering this question?

5. You are in a Hollywood film in which Love is postulated as the fifth fundamental force. Derive a plausible extension of the Standard Model of particle physics to include the Love Force, based on its observed effects at a macro level (flushed cheeks, hormonal release, last-minute assignations in airports, etc.).
