I have the following question: Assume a fast moving object is emitting a photon. The photon energy is E1=hν1Due to the Doppler effect observer will receive the same photon with energy E2= hν2. As E2≠E1, the energy conservation law is broken. Attempts to explain this using relativity theory are not convincing because energy E2 depends not only on the speed V of the fast moving object but also on the direction (towards or from the observer) while Lorenz transformation are direction independent.

Introduction to quantum mechanics
I don't know what you were trying to do to introduction to quantum mechanics, but the net effect was that you deleted all 23 notes. That is why I reverted. Please be more careful next time you edit an article! Thank you.--P.wormer 13:06, 19 July 2007 (UTC) PS. Science related questions can be asked here
