comment Is passing on knowledge/information from one body to another and the resultant state is ever studied as any branch of physics?
You may be interested, speaking of Physics, in the concept of entropy, Shannon information theory, quantum information, Kolmogorov complexity. Look them up on Wikipedia, you may like them. However, as already noted, seems like your question (and, most of all, your example) could be better answered in a Biology forum.

comment Why doesn't the LHC accelerate electrons?
You are right, but still the disadvantages of a lepton collider are counterbalanced by the much cleaner events you get. So it seems to me that the two approaches have been competing, and I wouldn't be so decisive in declaring circular electron/positron collider not viable. There have been some serious proposals: arxiv.org/abs/1305.6498

comment Radiation pressure question
You guess is right, the pressure must be very slight. And you have to compare it with the gravitational force, which basically keeps the planets on their orbit. This force is so much stronger than the radiation pressure, that makes is essentially irrelevant.

comment What is charge?
Actually at microscopical level, speaking of electrons and elementary particles, the charge is an elementary property. So the electron has charge $-e$, because it's like that. It determines how it couples to the electromagnetic field, the strength of the coupling, speaking more precisely. Why it's like that is not explained by the Standard Model, which is currently the broadest, widely accepted theory describing (among many other phenomena) the electromagnetic field.

comment Proving a step in this field-theoretic derivation of the Bogoliubov de Gennes (BdG) equations
Write the differential operator $\nabla^2$ in terms of derivatives as $\nabla^2 = \partial_x^2 + \partial_y^2 + \partial_z^2 $. Write each derivative as a limit (i.e.: $\partial_x f(x) = \lim_{h \to 0} \frac{f(x+h)-f(x)}{h} $). Rearrange the field by putting $\psi_\downarrow \left( \mathbf{r}' \right)$ on the left, of course keep track of fermionic exchanges with a minus sign. Reinstate the limit as a derivative and then as a differential operator.

comment Which types of particles are affected by the wave-particle duality?
I'm not that expert on experiments... However there are "standard" double slit experiments, and in recent times people have tried to see wave-like behaviors for bigger particles... The furthest we got is the Zwillinger's experiments (C60 diffraction, the experiment I was quoting) as far as I know.
