This blog was started by a PhD student in Bose-Einstein Condensation (Theoretical Atomic Physics) in a US University, to write something on Quantum Mechanics and the phenomena which can be better explained quantum mechanically. The blogger was born on the lap of the HIMALAYAS !

When You're a KET !
Paul Dirac, a famous quantum physicist, introduced in 1930 a unique notation called a 'KET' to represent the state of a quantum system . To define a scalar product, there is another notation, called a 'BRA', so that we can define a scalar product 'BRA-KET', which gives a number. This notation greatly simplified the mathematical development of Quantum Mechanics.
