### QUANTUM PHYSICS By Professor Balakrishnan - IIT Madras

Lecture Series on Quantum Physics by Prof.V.Balakrishnan, Department of Physics, IIT Madras. For more details on NPTEL visit http://nptel.iitm.ac.in Thanks to Physics de Pristine### Introduction to Quantum Mechanics, Probability Amplitudes and Quantum States

In this series of physics lectures, Professor J.J. Binney explains how probabilities are obtained from quantum amplitudes, why they give rise to quantum interference, the concept of a complete set of amplitudes and how this defines a "quantum...Breakdown of predictability in gravitational collapse

S. W. Hawking* Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Cambridge, England and California Institute of Technology, Pasadena, California 91125 Received 25 August 1975; published in the issue dated 15 November 1976 The principle of equivalence, whic...Tags: density matrix, wavefunction, s-matrix, superscattering operator, black hole, quantum-mechanical evaporation, information paradox, quantum mechanics, hawking

### The pilot-wave dynamics of walking droplets

By Daniel M. Harris & John W. M. Bush Department of Mathematics, MIT Further information: http://math.mit.edu/~bush/?page_id=484 Background: It has been known for some time that a drop can bounce indefinitely on the surface of a vibrating fluid...Black Holes: Complementarity or Firewalls?

Ahmed Almheiri, Donald Marolf, Joseph Polchinski, James Sully (Submitted on 13 Jul 2012 (v1), last revised 13 Apr 2013 (this version, v4)) We argue that the following three statements cannot all be true: (i) Hawking radiation is in a pure state, (ii) the information carried by th...Tags: black hole, firewall, information paradox, hawking radiation, quantum mechanics, gravity, einstein

### Nima Arkani-Hamed Public Lecture: Quantum Mechanics and Spacetime in the 21st Century

Dr. Nima Arkani-Hamed (Perimeter Institute and Institute for Advanced Study) delivers the second lecture of the 2014/15 Perimeter Institute Public Lecture Series, in Waterloo, Ontario, Canada. Held at Perimeter Institute and webcast live worldwide...### Gravity and Quantum Mechanics - The Quest for Unification | Joe Polchinski

Joe Polchinski KITP Mar 6, 2013 Quantum mechanics and relativity tell us that when we look at the very small, the very fast, or the very massive - then space, time, and matter behave in new and exotic ways. Each of these theories works well in its...Special and General Theory of Relativity by Albert Einstein is meeting the quanta

STR (Special Theory of Relativity) indicates a covariance of time to velocity of an object (matter with mass) in motion within an inertial system. The twins pardox is not a paradox: time dilation is due to the constant speed of light in vacuum, symmetries and laws of energy conservatio.........

Five unsolved problems in Theoretical Physics by Michael Balmer

Five unsolved problems in Theoretical Physics ,there are more so i don’t want anyone to think we only have five,even of the five there is only one to discuss being more important than the others. Problem 1 :Combine General Relativity with Quantum Mechanics Problem 2:The foundations of Qua.........
