Thanks everyone for your replies. Dove and Stevie have given detailed answers which have give me more insight(no,you have not confused me,Dove). But due to my lack of acquaintance with Dirac's formalism,I have found the latter part a bit of a stretch,though I am not asking any clarification,just...

Thanks.Will Do.

Thank you Aravind,Hubewa and Russ. You have given me more insight not only to my question but also to the presentation of a question. So the bottom line is energy is an inherent entity in the universe and it's presence is ascertained only by it's effect on measurable parameters.

Hi San, You've given a true answer.But,then again how do we know an instrument has collapsed the wave function without us analysing the instrument?Do we effect the wave function collapse then or not?

Qualifications of an "Observer" I believe that Quantum Mechanics places an onus on an "Observer" to collapse the wave function of any particle(take an electron for example). My question is what defines an "Observer"?What are the necessary attributes required to be an observer? I have read...

I am really sorry. I meant to say,"Do we feel energy only as a cause and never as itself?". Let's say,we feel the effect of heat energy,temperature,we don't feel heat energy itself now,do we?

Using Thermodynamics we can measure a certain quantity that is preserved/transferred during a process and we call it energy. We feel it's existence based on it's effect on other observable quantities(say motion for instance) and we do not "know" energy as itself.Am I right? So do we energy...
