I am looking for a few interesting sheets of foil with special properties. For example, Magnetic paper, solar filter paper, diffraction grating foil. I also know that there is a thermal paper that ...
I'm new to wave problems, so excuse my simplified words. I have a signal consists of high range of frequencies . I applied a Band-pass filter to this signal and I have been able to separate it to ...

http://en.wikipedia.org/wiki/Explosively_pumped_flux_compression_generator Explosively Pumped Flux Compression Generator detonated a mile away or so, what damage would be done to my phone, and other ...
Where did the formula $Φ(x,y,z) = x^3y - z^2$ come from? How does it define a scalar field? [closed]
I want to ask that why $Φ(x,y,z) = x^3y - z^2$. I don't understand this relation? Can someone make sense of this equation.
Consider a one-dimensional semi-bounded "ray" (or thin "cylinder") of stratum (or just any homogeneous substance) which has several "features" along it's length (say, thin films). Consider a wave that ...
I am looking at this formula: from wiki for brakedown voltage in gas discahrge lamps, and I see it's linear by length (d) (ops, I see it's divided by ln...). Does that mean that I can make tiny ...
In tonight's session of a science fiction role-playing game, I used a white phosphorous grenade against a group of ammonia-breathing aliens on their home turf, and I must confess that neither the GM ...
Coleman-Mandula is often cited as being the key theorem that leads us to consider Supersymmetry for unification. An overview discussion with sufficient detail is missing in many popular texts. So ...
