What is 2*2?

Several scientists were all posed the following question: "What is 2 * 2 ?"  

• The engineer whips out his slide rule (so it's old) and shuffles it back and forth, and finally announces "3.99".
• The physicist consults his technical references, sets up the problem on his computer, and announces "it lies between 3.98 and 4.02".
• The mathematician cogitates for a while, then announces: "I don't know what the answer is, but I can tell you, an answer exists!".
• Philosopher smiles: "But what do you mean by 2 * 2 ?"
• Logician replies: "Please define 2 * 2 more precisely."
• The sociologist: "I don't know, but is was nice talking about it".
• Behavioral Ecologist: "A polygamous mating system".
• Medical Student : "4" 
• All others looking astonished : "How did you know ??" Medical Student : :I memorized it."

Physics of FSc Pakistan

I am a student of Fsc 1st year in a normal private high school in a small city of Hazara, Pakistan. When I went to America on an exchange program through YES-Pakistan, I felt the need of being in touch of the courses taught in Pakistan. I searched for hours and hours on internet but was never able to find any book of science (Physics, Chemistry, Maths) from the courses taught in Pakistan. So, I wasn't able to compare. I was a lot depressed because I never knew all the courses I learned in Pakistan nor even the courses that was coming up in the next classes. Now after I am back from USA, I want to gather the work of Khan Academy in a sequence for my other Pakistani fellows who want to learn from internet besides from their teacher.  I want my fellow Pakistani to be equipped with more advanced knowledge, just like the students of advanced countries are getting in their life. I want an educated and well-civilized nation. Thanks to Khan academy for their work that I am spreading. These lectures are in English so there is a chance of improving English also.

Below are the topics that deal with Physics taught in FSc of Pakistan:

Chapter 2:

2A.1   Scalar and Vectors (Introduction)
2A.2   Definition of some special vectors
