DYK-04 Who Revived the Klein Gordon Equation?Node id: 1828pageThe Klein Gordon equation in its original interpretation suffered from problem of negative probabilities. After quantum electrodynamics was successfully formulated, the second quantized Klein Gordon equation was shown to give a consistent formulation for spin zero particles. WHO DID THIS WORK? |

DYK-03 Jacobi Action PrincipleNode id: 1827pageJacobi Action Principle
A Second Variational Principle for Conservative Systems
Hamilton.'s action principle in classical mechanics is widely taught. There is a lesser known, but important Jacobi principle which is like Fermat's principle for waves. This form of action principle was used by Schrodinger to arrive at his hafous equation for qunatum mechanics of a point particles. |

Works of Masters always have something to offerNode id: 723pageI take the best from every one. But GOLD FROM OLD,
There is always something to learn from MASTERS;
In this age of internet, there is a tendency to open internet and learn from Wikipedia and similar sites. While this has its own advantages for a mature learner, I recommend that a beginner must learn from the masters even though the learning curve may look very steep. This collection is an attempt to encourage younger generation to leart role of contibuting to the subject and from the very best. There are many who contributed to pedgogy and teaching. Many old texts become 'obsolete' simply because is it fashionable to go for the latest. It would be foolhardy to ignore these and other works, so we include here snippets and quotes etc. from many other sources too. It is hoped this will provide incentive to the younger generations to ask for more. "Choose the very best from every one" |
