comment Meaning and application of convolution or deconvolution in physical sciences
the point of googling stuff has been discussed at length on all the meta sites since the very inception of SE, and the conclusion forms the very philosophy behind SE sites. We want to localize knowledge, not point to links that can become outdated. The goal is to have this answer as the first google entry (see: "google as an interface" SE concept) so that people can learn immediately a well-written answer to a very specific question. I encourage you to browse the meta sites (not only the physics meta, but stackoverflow meta as well), to see the rationale behind my point.

comment Books that develop interest & critical thinking among high school students
@Mark : I have experienced it, don't worry. I played everything playable (I'm not kidding, we had a computer shop so I had all games released in a 10 yrs timespan) on C64 and Ami1200. On PS/XBox, I'm updated enough to know what's going on, and play games I consider worthy (e.g. Uncharted series or Portal). This is however, orthogonal to the argument. What I want to say is that Xbox is a strong attractor, and you need something really strong and cool to redirect interest without application of educational force (such as: first homework, then play, which is what any good parent should impose).

comment Does this statement make any sense?
@Cedric: maybe, maybe not. I think his friend is in good faith. He is just confusing things and assumes he knows technical facts. in reality, he is putting together a partial and incorrect vision to form something which is, in the end, improper. I think it's our duty to clarify their misunderstanding, if they want to listen.

I am answering your friend in an actual answer.

comment Books that develop interest & critical thinking among high school students
I'm not sure it's on topic, although I love the subject. In any case, I'm not sure you will get interest from books. There are (few) students who still don't think all their life is XBox and junk food. These students are captured even with paper lifted by a charged pen, so you need to feed them right, but you don't have to capture their attention, it's already captured. If you want to capture attention of the Xbox junkies, you need something else entirely. A book won't do, not as a starting point

comment Meaning and application of convolution or deconvolution in physical sciences
@Cedric I'm trying to find a real case, simple scenario where a convolution is used. I don't think we are going to have an endless list. I am looking for a very specific answer, the one that explains clearly how a convolution/deconvolution is practically used in real-world science.

I love when people use technobabble they know nothing about to work around their ignorance :)

comment Home experiments to derive the speed of light?
you have to know the frequency of the microwave, though.

comment What methods can astronomers use to find a black hole?
Hawking radiation is inversely proportional to the black hole mass, so I don't really hold my breath for having a detector able to see Hawking radiation from ordinary black holes.

comment What are the most fundamental assumptions of quantum mechanics?
as a quantum chemist would say, yes, it exists, but its projection in the english space has lower dimension, thus has a larger error due to the variational theorem.

@mumtaz:The electron is technically handled as a dimensionless point, but it's irrelevant. What you work on is the coordinate of an electron, but what you have is a coordinate of space where an electron's wavefunction has a given value. when you say wavefunction $\psi(x)$, your $x$ is a dimensionless point, but it's not really like you have a infinitesimal particle stuck in point $x$.

This is hardly in plain english ;)

comment What are the most fundamental assumptions of quantum mechanics?
I would not say "probabilistic existence". It's not like if you say "the electron has, say, 40% probability of being here" does not mean that it spends its time 40% here and 60% somewhere else. I think the plucked string is the most appropriate real-world example. It's not like in the middle of the string there's all the vibration 40 % of the time, and 60% is somewhere else. The vibration is just 40 % there and 60 % on the rest of the string.

what do you mean with assumptions ?
