You know Einstein was very clever. (Information Theory in Physics )

Then he goes S = Int{Ldt}, action is the total amount of specified definitions of energy over all of time, and action is a kind of information if we are dealing with a statistical system of L {energy} because Energy is not known precisely, or rather action is not, this fact is brought in by saying the time is an information or a PLAN, because things are not known precisely although depend on other well defined factors. Then he sees that since interactions of different chunks of Energy with each other which are not known very precisely gives rise to heat or temperature, temperature here serves as information or PLAN. Then this is still called S, akin to action because S again is information or imprecise or statistical. Then they call it Entropy. {Perhaps for INTERnal-Energy = Intropy} But this other factor temperature also is denoted by same initial T. Since T has to be a fundamental parameter as are Energy and Entropy it can go anywhere, in denominator or numerator and sitting below sometimes feels good so they give T the chance to do that. Its better to heat from below. Heat works that way. But Time T sits on top, see: S = Int{Ldt}. More…

Triangles and Particle Physics !

Phase Space.

When we deal with what we call particle physics, we always have to bring into discussion; whats a phase space. Its the most basic thing to do, in that involvement. Its like each time we make pizza we have to think of whats the dough and whats the topping. At-least the theoretical and experimental particle physicists would think so.

Whats phase space? How is it that the special relativity was hidden into a small angle?

Lets first talk phase space.

Phase space literally means a space of angles. A phase is an angle. But what is the angle? The angle that gives us the direction of momentum. And the magnitude of the momentum is directly connected to the energy. More…

Basic ideas of Particle Physics.. A Klong Meson
^{
4 }

Another example of importance of Particle Physics as is understood by the general public is Blackhole. Well see blackhole is not a particle-phyics idea but the general public knows LHC is a particle-physics lab which produces blackholes that can engulf the world. Such was the paranoia in the year 2008 before LHC had started banging its protons into protons at the speed of light. In roughly 4 years the Higgs-like has been discovered. Why I say its a Higgs-like and not a Higgs? Because the Scientists are not perfectly sure that Higgs is that which they have found. If you want to remember Higgs here is a hint: it sounds like Eggs. {like in my eggs-girlfriend, My Higgs-girlfriend and my ex-girlfriend don’t they all sound the same?} More…

Basic concepts of Monte Carlo and reconstruction.
^{
1 }

This scheme as you could see is only a flip-flop and works to check if this works and my toy Monte Carlo proved that it does. But in real situations this Dzero mass constraint is used to recover the Klong 4-vector which also means we have the Dzero full-info now. But we input some Dzero info as given {its mass} hence its only trivial. But we can add this Dzero to other released particles in the topography and see the signal in terms of D* particle. More…
