comment Is the Higgs a quantum field or a particle?
I agree that we cannot really claim at this point that the Higgs is elementary.

comment Why is Mendel Sachs's work not taken seriously? Or is it?
Quantity of work is a poor measure of the work's value.

comment Constraining two-point functions of boundary operators on the disk
I am certainly assuming unitarity. The fact that correlators of descendants are determined in terms of primaries is of course true, which is why we don't usually care about such correlators. Perhaps this is enough for your purposes, but note that this alone does not imply that the pairs of correlators you asked about are at all related to each other: each could be related to a different correlator of primaries. My suggestion is that they are in fact related.

comment Constraining two-point functions of boundary operators on the disk
Yes, I see what you mean now. I added an idea for the descendants.

comment Change in appearance of liquid drop due to gravity
@CrazyBuddy What confuses me at least is that you call them 'horizontal' lines -- I never saw a raindrop that looks like that. That is why I thought you meant this flattening. Do you mean vertical lines?

comment Change in appearance of liquid drop due to gravity
Their shape depends on their size. Small drops are spherical, larger ones look sort of like pancakes (this is what I mean by 'flat', perhaps this was not clear), yet larger ones look like parachutes. I don't know at which size (if any) they become elongated, but the shape is due to the flow of air and not gravity. I will try to clarify...

comment What is the fundamental differences between bound and entangled states
Sorry, but I do not understand what you are asking. Specifically the phrases "the particle and the energy are bound to the process of entanglement" and "energy is determined to stay bound ..." make no sense to me. The photons do not exist before the decay. They are created when the particle decays.
