This exchange is between myself and my Year 12 Physics teacher after final exams were over and we were on holiday.
I thought it was quite Highlarious.

I've been going over STAWA just for the hell of it and I have come across a question that I cannot do. This has left me feeling depressed and insecure, questioning my worth as a human being.
Does this mean I failed the TEE? Will I get a good job to sustain my family? Will I get a family? What can I do regarding this body odour?
All these questions flooded my mind at once, crowding the space which I normally use for formulating tatics and combos In Final Fantasy. Needless to say, this worried me even more. With that part of my brain out of commision my gameplay suffered immensly. No longer could I micromanage. No longer could I set up a organised rush against the enemy base. No longer could I decide when to have lunch and where.
Malnutrition hit me hard. Not because I thought I was fat but because I couldn't decide what to eat. The consequences were dire. Spiraling into a vicious cycle wherein there was no energy supply to my brain therefore the question became even harde to solve due to my weakened state and thus less energy was supplied. I went into convulsions, halucinating about Tetris and Pacman and in my state of craziness I devised a completely new game entitled "Tetman" where you are a Tetrimo moving around a maze by spinning, collecting pellets.
But I digress.
So in order to break me out of this cycle I need your help.
The physics question is:
A generator coil contains 200 turns and is 30 mm in diameter. It experienced a uniform density change of 0.5 T in 10 s. Calculate the average induced EMF in the coil.
On a completely unrelated note, I tried reading the entirety of Lord of the Rings, yesterday, in one sitting. I got up to page 56 before I got tired.
I need to train more. Oh wait, I have a Wii Fit now so I can be insulted and called a couch potato in one session then a muscle legend in another.
So yeah,
Hope you're having fun writing reports and whatnot

Hi Jeremy,
After reading your "question" I have become convinced that although I gave you an "A", perhaps I failed to teach you some of the more important things in life...such as GET OUT MORE OFTEN!
Why, oh why are you studying electromagnetism.....anyway the answer ...
A generator coil contains 200 turns and is 30 mm in diameter. It experienced a uniform density change of 0.5 T in 10 s. Calculate the average induced EMF in the coil.
EMF =change in flux / time
= (0.5 x pi (0.015^2))x200/10
= 0.007 V
= 7mV
(I hope this is correct!)
Have fun,
Mr D

Cause you said....you said.
That if we asked you a physics question during Leavers you would be impressed.
So I was merely complying to your advice.
....it is leavers now is it? I don't know.
Anywho I'm off anyway.
Places to go, people to kill

hmmm....yes I do seem to recall saying that.
And, unfortunately, I am not as impressed as I thought I would be.
Oh well.
I have just finished my reports, so I can now go out to play!
Wait. Go
out to play?
What are you talking about? Or are you going to take your laptop to the beach?
Anyway, enough of that.
I think I might give my keyboard a clean
