Do diagrams that show unit cells with atom/s located at each lattice point actually represent the "centre" of atom/s? When we see pictures of unit cells the lattice points are spread apart and you get 3-D box like constructions. As there are no spaces between atoms in unit cells I assume that we are actually looking at atom centres for each lattice point?

I noticed that the voice that i hear of myself is different from what I hear when I record my voice. Then, I asked other people if this is my voice and they said it is. So does the voice you hear of yourself have a different sound than how others hear it?

If we take a lattice in 2-D and link lattice points together with lines in different directions, will only certain lines become crystal faces? I have a hard follow diagram which shows a horinzonal line across the lattice and a vertical line up the lattice as lines that would form crystal faces. There a few other shorter lines on the diagram linking a few lattice points but I don't know if they would become crystal faces.

I'm thinking of taking window tinting film slightly bigger than the windshield and sticking hair thin copper wires to the sticky side about 1 cm apart from each other (like the rear window). Then sticking that to the inside of the windshield and trimming the edges. Then painstakingly attaching each heating wire to a larger wire at the left and right sides of the windshield and suppling power to those wires. It should get warm enough to defrost or defog. But I'm worried about the plastic melting, bad visibility, wires breaking on installation or air bubbles. Does anybody know where I can get something like this already made or better ideas on how to build this.

The Pizza Palace found some pre-inflation menus. An 8" pizza was only $0.85 and a medium pizza was $1.15. The equation for this quadratic function is p = d2 - 3d + 45

Suppose the menu listed a "Colossal pizza" for $6.00. What would the diameter of that pizza be?

Im trying to build my own air powered actuators for a robotic arm. But to control them ill need some solenoid valves of some sort. I don't know the exact pressure yet, but ill use around 50-100 psi. I keep searching and don't really see to many cheap ones. They can be reall cheap after all this is just an experiment all it needs to do is open and close pritty fast.
