    Quantum Books on Quantum Mechanics

    Dear Sir , actually I studied all courses from Classical Physics to Modern Physics. But , as you know as time passes , we try to get more refined and deep thinking over the matter , for example , force is equal to the rate of change of momentum w.r.t time. Then how Newton came to this , has not...

    Max. Scholarship gained by student for in MSC in USA

    GRE EXAM for admission in postgraduation in physics in USA is of 340 marks. If one scores 330/340 then how much maximum scholarship could he get for masters in a good USA university for physics, he has done research work too? And would he also get reduction in accommodation and mess fees, if...

    Courses CSE at the age of 21

    No, sir. I want to be like Alan turing. Physics and mathematics (which already I am with) and computers. It is because I am self-motivated in computers too. I mean, a computer engineer, too.

    Courses CSE at the age of 21

    Hi, I am from India. I will be getting my honors for Bachelor's degree for physics in a few days. I am 21. As members at this forum are from USA too, so I want to know if I take exams like GRE, IELTS, TOEFL and get admission in USA, just suppose. Then, in any way, would I be able to be the same...

    Battery connected to a pure inductor with a Zero-resistance wire

    You may be right. So, is there anyone and you who knows the mechanism of this circuit?

    Battery connected to a pure inductor with a Zero-resistance wire

    As a current even starts to gain a slight value in the circuit, for even such a very short value of current like 0.000001mA, the slope (di/dt) would still be very large or same for the current rising afterwards. And thus, voltage across the inductor will be infinity or very large. Doesn't it...

    Battery connected to a pure inductor with a Zero-resistance wire

    I know the mechanism of a circuit containing just a capacitor connected to battery in resistance less wire. The particles are just tending towards making same emf on capacitor. But, I am not able to think clearly for the case of inductor. As, we connect battery and as resistance is 0.So,current...

    Computers for understanding physics

    Is it possible that people would be able to know about each natural phenomenon with the help of computers. I don't think so because how one will know about the quantum mechanics or high energy physics! So, I mean that only humans can only do this, right? Or, is going to be possible in the...

    Physics Experiments for theorists?

    We know the fact that we physicists are now understanding physics only mathematically(string theory) , there is not even a single physical variable(except time, space) in the equations. Yes, obviously, it had to happen because how much far can my eye see? It had already started from quantum...

    I Nature of contact force

    Yes, but as electrons are repelling each other at the molecular level. Similarly, the protons are attracting the electrons of other atoms too. So, u can't say for sure what will be the resultant force between the atoms I mean attractive or repulsive.

    As we draw the electric field lines due to 2 equal magnitude and same nature charges. But when we solve the question concerning the same case we take the resultant of forces due to both charges at a test charge in such a manner that the 2nd charge(let I put the test charge on the left side i.e...

    I Nature of contact force

    If friction is electromagnetically attractive force and the normal reaction is electromagnetically repulsive force which it obviously is. But how is it possible to have different type of force as the component of a single force i. e. Contact force over the nature of which I have got confused!
