Wikipedia FTW!
You know that you must at least refer to your the textbooks in order to get good grades for your university subjects (directly quoted from my Material Science Tutor).
I seriously think that my lecturers and tutors are earning some kind of commission from the publishers every time a textbook they recommended are bought.
What happens to el cheapos like me who won't buy the ZOMG! expensive textbook they are pushing to us? Go to the libraries then!
But what if I'm at home and I need to refer to some textbook?
I refer to Wikipedia.
Unless you're living under some rock or Potong Pasir and Hougang where they don't have internet access, Wikipedia is a free online encyclopaedia where anyone can edit.
So next time when you don't really know what's Torque, Angular Momentum or even Moment of Inertia. Check out Wikipedia!

The above is not a paid advertisement by Wikipedia. I do not receive any payment, in anyway or form, from Wikipedia by mentioning their website on my blog (I sure be happy if I receive some payment!)
I also sincerely apologise to all Potong Pasir and Hougang residents out there who are offended by that thoughtless comment about Potong Pasir and Hougang. It is not my intention to slight those who had voted for the opposition in any way.
