Newton's Laws for Rotation.

1st Law : The rotational principle of inertia:
The rotational principle of inertia: In the absence of a net applied torque, the angular velocity remains unchanged.

2nd Law: The rate of change of Angular Momentum:

τ = I α

This is not as general a relationship as the linear one because the moment of inertia, I, is not strictly a scalar quantity. The rotational equation is limited to rotation about a single principal axis, which in simple cases is an axis of symmetry.

3rd Law: Reaction Torque:

For every applied torque, there is an equal and opposite reaction torque. (A result of Newton's 3^rd law of linear motion.)

If we can somehow cheat any of these laws we can have perpetual machines requiring no energy inputs.

What are The Best Institutions for Higher Education in India?

All Institute of National Importance are Best Place for Higher education in India.

Institute of National Importance (INI) is a status that may be conferred to a public higher education institution in India by an act of parliament, an institution which "serves as a pivotal player in developing highly skilled personnel within the specified region of the country/state". INIs receive special recognition and funding. As of 23 April 2015 the Ministry of Human Resource Development has listed 74 institutions under this category.^[1] AllNational Institutes of Technology, Indian Institutes of Technology, School of Planning and Architecture, Indian Institutes of Science Education and Research and All India Institute of Medical Sciences are considered Institutes of National Importance.

Visit Wikipedia for further detail.

Please note there are also Institute which are not in this list but they also very good e.g.

• TIFR Mumbai
• IISC Banglore
• All the IIMs

1. Who rules the Universe? 2. What is the Ultimate Question? 3. Who is Zaphod Beeblebrox?

Q.1. Who rules the Universe? Q.2. What is the Ultimate Question? Q.3. Who is Zaphod Beeblebrox?

Well I will not answer the Question 1 & 2 right now but maybe later.

Zaphod Beeblebrox was once the President of Our Galaxy, Milkyway.
He delivered his duty as President very diligently otherwise he was very irresponsible.
He also discovered Pan Galactic Gargle Blaster.
Want to know more about him, Then Read "The Hitchhiker's Guide to the Galaxy".

Good Physics Books for IITJEE

Hi Folks!

Let me tell me you about the importance of reading only good books and nothing else.

What is a Good book?
Good books have a theme in them, they are like watching a TV series, each chapter is related to other chapters. They are written by a person of vast knowledge and interest.
Good books give real knowledge, comfort and are interesting.


What is bad book?
Bad books are written by people of shallow knowledge Or by too many uncoordinated people. The are mostly copy of Various good books.
Bad books cause nothing more than confusion and distress and are boring.

What is Average Book?
In between the two.


So read only good books and nothing else.

Let me suggest some of the good books :

Physics :
1.
Fundamentals of Physics , By:  Halliday, Resnick and Walker

My comments on this :
I have read it when I prepared for IITJEE in 2002, I say no other book can replace it.
Very good for theory and concepts.
Fairly good for 50% of IITJEE Questions.
You don't have to do its all the Numerical problems given at the end, you skip 50-70% easily, without any harm.

2.
For difficult numerical try to solve only 50 % of Irodov Problems in Physics, even if you see the solutions and understood, it will help a lot.
The best part of Irodov is that it deals with Characters instead of numerical values, so you are doing lots of theorems.
