Ah, so much to say.
First off, I absolutely LOVE these riddles. My brother (comp. engineer) has to answer extremely tough ones for job interviews and it is really stressful.
I'll give you two examples:
You have 8 balls...1 of the balls is abnormally heavy. You have a counterbalancing scale and the balls. How many trials does it take to find the abnormal ball and explain how you should conduct the trials?
There are 50 lockers. They are all closed. On your first trip through the locker, you open all of them. On your second trip, you close every 2nd one (ie locker 2, 4, 6, 8). On the third trip, you TOGGLE (meaning change...open to close or close to open) every 3rd locker (ie locker 3 6 9) etc until your 50th trip when you toggle the 50th locker.
At the end of all 50 trips, how many lockers are open and which ones are they?
Now to personal notes:
Love the avatar Brett..go play some golf and relax.
Congrats to scenti and Teera on their interviews.
Good luck to all August 2006 MCATers (tucker, will, nikki and donut and anyone else I missed)
Since I'm in the quizzing mode, here's an MCAT question (or at least I think it is):
We all know that PV=nRT is the general equation for ideal gases. However, under circumstances, this is not the case and there is a deviation. Explain the following situations by describing the differences between real gases and ideal gases:
Assuming n =1, PV/RT > 1
Assuming n = 1, PV/RT < 1
(Sorry if I wrote the question down incorrectly or vaguely...I just wanted to do a theory question. 😉 )
