I have been wondering why photons can't go through matter and electromagnetic fields mostly unaffected while neutrinos can. Neither of them have an electric charge as a particle, and the basic description I see about neutrinos is always that "they are unaffected because they have zero electric...
yes ok i see your point.
no need to be hostile, what i meant to ask was why it's an even function in general. so i could also phrase it like
\delta (x-h) = \delta (-x+h)
or just give a number
\delta (x-5) = \delta (-x+5)
In this case I just felt like the "spike" formed by the delta function...
Hi this is my first post here so I'm sorry if my question seems trivial.
I haven't worked a lot with the dirac delta function before, so i always thought that the shifting property would only work as:
\int\delta(x-h)\;f(x)\;dx=f(h)
Now I've been reading some articles and I came across...
