  • New forms of Uncertainty Relationships in Quantum Mechanics.

    ΔE.Δt ~ h Δp.Δx ~ h ΔL.Δθ  ~ h * Shouldn’t the constant above be ℏ/2 ? Let us first clear up some air of confusion. The above relations are kind of vague even though look like canonically powerful ways to represent the formal concepts of the Heisenberg Uncertainty relationships. I have myself confused with these at times … with…

  • Uncertainty Principle and Photography !

    why a moving object becomes fuzzy when you take its picture. Speed bears an uncertainty with momentum (hence energy ) just like time with energy and position with momentum. But for photons which are always ultra-relativistic we should not talk about its positions. Due to speed (relative motion of objects such as your and moving…

  • There is only one physical favor the Universe did on life.

    But all of them are not stable. We have made great strides in understanding them collectively called as standard model of particle physics which involves electroweak and strong interactions. Its a weird mess of beautiful list of particles and their behavior toward each other. Sometimes there is symmetry breaking sometimes there is symmetry and sometimes…

  • Why is the helicity for a mass-less particle Lorentz invariant?

    Result; now that photons are mass-less, their energy, momentum, speed, etc are no more variables, in the sense of arbitrariness. They are constants, taking only a few values, but constant in a given situation. But other particles have these properties; arbitrary. So electrons energy and momentum are not fixed, but arbitrary. But as long as…

  • Nature of photons.

    Also (without any direct theoretical connection, but correlation through reality of nature) 3. Photons are classical only in the sense that we perceive light only when photons are produced in large numbers. So large that the laws of the small do not incur large errors because they are in large numbers. Statistically the errors are…
