E= hv= mc2

You are blue and young, only a few light years away.
I wait for eternal darkness to arrive every evening,
for you to bright up a halo with a burst of energy.
Your constant smile in Hubble's universe and
your dancing photons are equations of my future.
If you see my mother, tell her to slow down.
If you see my dad, tell him to take good rest;
he is running all his life in four dimensions.

You are young and brilliant blue of midnight horizon.
My feet on an arrow of time start to break the blindness
and follow your light amid cacophony of wide open field.
When I get tired, I renew myself by the shower of your duality,
eh! dazzling wave-particle on the tangent of summer curvature.
I am closer to your blue frequency now more than ever.
Let us dance together at a rhythm of our resonance.
We are a star of infinite darkness, my matter-morphosis!

The equations of motion in Newtonian mechanics were replaced by similar equations between matrices; it was a strange experience to find that many of the old results of Newtonian mechanics, like conservation of energy etc., could be derived also in the new scheme. Later the investigations of Born, Jordan and Dirac showed that the matrices representing position and momentum of the electron do not commute. This later fact demonstrated clearly the essential difference between quantum mechanics and classical mechanics.

The difference between Newtonian mechanics and Einstein's theory of relativity is this: In classical theory we assume that future and past are separated by an infinitely short time interval which we may call the present moment. In the theory of relativity we have learned that the situation is different: future and past are separated by a finite time interval the length of which depends on the distance from the observer. Any action can only be propagated by a velocity smaller than or equal to the velocity of light. Therefore, an observer can at a given instant neither know of nor influence any event at a distant point which takes place between two characteristic times. The one time is the instant at which a light signal has to be given from the point of the event in order to reach the observer at the instant of observation. The other time is the instant at which a light signal, given by the observer at the instant of observation, reaches the point of the event. The whole finite time interval between these two instants may be said to belong to the "present time" for the observer at the instant of observation. Any event taking place between the two characteristic times may be called "simultaneous" with the act of observation.
