If you get electrocuted can you see your skeleton (like in the cartoons)? I have saved up the money and am ready to get a 500,000 volt tazer but I'm not sure if that will be powerfull enough, is there a better way of testing this (short of flying a kite in a storm)?

Unpolarized light, which travels in the z-direction and has frequency f0, enters a linear polarizer with a Transmission Axis (TA) inclined at an angle of 45 degrees with respect to the x-axis. It then enters a birefringent slab and emerges as circularly polarized light. The TA and the fast and slow axes of the birefrigent slab are parallel to the xy plane

With the slab oriented as shown in the figure, the light frequency is doubled to 2 f0. After the light emerges from the birefringent slab, it is:
a) unpolarized
b) circularly polarized
c) linearly polarized

the answer is c) but I cant figure it out for the life of me, can anyone explain?

I have 2 cameras set up at different positions to record some positions in 3D space. Given the parameters of 2 cameras and the image coordinates of these points recorded by both cameras, how do I calculate the 3D coordinates of these points?

Would you fall all the way through the earth, coming out the other side, and fly into the sky, or would gravitational foces crush you at the center? Would you come to an immediate stop at the center, or be suspended in space weightless?

Dirac vaccum is an excellent question of symmetry why is the universe symettric and why is it not in some aspects
2)All the the vaccum has dark energy and dark matter does this mean to say that light only travels in a medium or someother....

Can you jump thru loopholes in time?
in other words.. instead of traveling from point A to point B
you BEND the spectrum until A and B are one and the same
therefore you never really travel at all.. you just jump thru the bend.

i dont, i recently proved this one wrong, einstien helped me with this part, if you get 2 particles, spin one left, the other goes right, now put one 200 light years away, spin the one on earth right, the other goes left, INSTANTLY, so the information is going faster than light, the speed of time, instantainiously., now heres my part, this proves 2 things, the speed of light isn't the fasted speed ever, and that the speed of time is the speed of information, so if you somehow went faster than this, you would dissapear because your atoms, which are information, couldn't keep up with you because your going faster than information, so your not going faster, it makes you dissapear before you get faster, and also i have heared that you need infinant energy to go faster than light, and there is not infinant energy in the whole universe. so thus explaining why time travel is not possible.

I just want to know if there is any way that could work. For example: a mixed stream of 50%/50% hydrogen and carbon monoxide comes from a container of heated coke when water is brought into contact with it (producer gas).

Can a vortex precipitator of the type usually used for removing dust separate the two gasses to any significant degree? Any idea how efficient this might be?

Similarly [I know, I know, this is almost a separate question] could such a vortex device separate a mixture of silica (SiO2) and alumina (Al2O3) particles in water?

Any ideas, suggestions that might work? A filter column won't work for insoluble substances, will it?

This is for an S/F story in a primitive setting with modern knowledge but without modern resources. But I want it to work right. Thanks, everybody!
