Title: PHYSICISTS ARE PEOPLE TOO

It's true! They even have rights and sometimes play bingo!

"To use plausible arguments in place of proofs, and thenceforth refer to these arguments as proofs."

"To approximate all problems to ideal cases."

Hehehehe. Guilty. It should be an approximation statement in general though.

But! A plausible argument IS a proof!  =/

Is a proof a plausible argument? :P

Is a square a rectangle? (yes)
Is a rectangle a square? (no)

Is a plausible argument a proof? Not really... :P

Well, I guess, a (correct) proof must be plausible... right? :D

I love how physics teachers always choose really odd things to write in questions. ;D

Can't believe we forgot this one
Travelling at a constant velocity

The people who write physics questions must have a liking of toy trains too. If you read through some circular motion and conservation of energy/momentum questions you seem to find trains popping up a lot. Just something I noticed in year 12 while doing checkpoints..

I think in our year 11 textbook there was a diagram of a whale being thrown off a cliff.

In Fundamentals of Physics there were diagrams of penguins being towed up slopes and shot out of cannons

Animal cruelty.

reminds me of TSFX Physics notes, with cows being shot out of cannons, dropped off buildings etc.

They got rid of it though recently though =\

Great book; I love it. It was my textbook last year. The penguin questions are the greatest.

Hey, I just borrowed the set from my Physics teacher today!!! (halliday/resnick/walker?)
Where are these penguin questions??? :D

and theres a few more but I cannot find them atm

Uni/Advanced high school physics and maybe Uni enhancement. It uses calculus a lot so it's not really VCE Physics 3/4 stuff.

Edit: The electromagnetism related chapters are fucking hardcore.

haha. NEver seen that question. There is a question in there about a penguin falling off a cliff but I can't find it. :(

Did your teacher lend you the 5-part version or the onebighugebookthatweighsatonne version? I find the 5 part one is much easier to carry around and good if you want to cram just one part before a test.

The five-part one, except I've only taken Part 1 home, I'll get the rest later :D
Thank god it's not the all-in-one-as-heavy-as-LOTR version

Olympiad uses the Halliday, Resnick and Krane version which has slightly different questions. I actually found the EM problem solving questions a bit easier than some of the other chapters - I've done them more recently, so perhaps I'm just improving at physics...

Oh ok, well this will do! Some light reading for the next few months! :D
