Dear prof. Unnikrishnan,
I am very much thankful to you for reading my essay and posting your lucid comments on it and I am glad to answer them point by point.
1) In QP, we can call definite states of matter as 'reality' but in CP, we can call matter itself as 'reality'. I don't see how the realities of both classical and quantum physics are mixed when I say "photons represent classical information as continuous collection of bits". Because photons (presently) are the only source (as far as I know there are no other sources) of information in CP although they characterize the quantum world and this need not mean mixing of realities of both CP and QP.
2) Although QM and S-equation are based on the continuous space and time back ground, it need not imply that at the 'quantum level' they are not discrete and according to me, discreteness follows from the very concept of 'quantization'. This is the reason for QP to be different from the CP and all dichotomy lies here, for otherwise CP could have explained the whole of QP.
3) If two quantum mechanically entangled particles are separated by a huge distance and measurement of correlated values are carried out, it is known from QM that the measurement of one value affects that of the corresponding value of another particle instantly. This is interpreted as, information travels instantly between the two particles irrespective of the distances between them. But such super luminal speed of information is prohibited by relativity and hence to comply with relativity the information cannot be physical but non-physical. If there is logical connection between the two measurements in QE, then how do we account for the instantaneous effect? (When I say 'non-physical' there are some reasons behind it and want to disclose it when I express my views on QE.)
4) You have mistaken what I have said in the biology section of 'The concept of Reality in Biology'. There I have said "there is no limit to the comprehension power of the human mind just as there is no limit to the horizon of his imagination. It can answer, over time, any question for which it seeks answer. Consequently there is no limit to his understanding of the physical Reality of the external world and it is unfettered by the structure of his brain". You have mistaken 'reality' to 'information'.
These are the reasons I have when I made above statements. You may (I think you will) have objection to the 2nd point, but that is how I view the dichotomy that exists between the CP and QP. I want to continue this dialogue in due course.
Best regards,
Sreenath
