Newton was a man who wrote a book that neither he nor anybody else could understand
----- Cambridge student
* So since Newton's time, the idea of Quantum Theory has been developed; and it could be the reason that some physics books are not easy to follow.

Experiments are the only means of knowledge at our disposal. The rest is poetry, imagination. ------ Planck
Q: When is the time for our imagination to unfold ? A: When the mathematical or physical experiment is done.

*** a fundamental idea about entropy

If there is no uncertainty, then the entropy is zero and we do not have to make a measurement, because we know what the result will be. No uncertainty, no information. No pain, no gain.
Information is associated with uncertainty and entropy. Before we observe an oscillator, its displacement, momentum, frequency,phase, and energy are completely uncertain. ...... When entropy is low, a small amount of information removes a relatively large uncertainty. When entropy is high, a large amount of information is required. --- But all of this is statistical, and a.e. we look we see systems with low entropy, far from thermodyamic equilibrium
