That app in the previous post has a nice guided tour, with more to come.
Here's a link to a short news story with some additional amazing images

In my experience, it's common for the client to own everything they've paid for without having to acknowledge the source (consultant). The "non-disclosure" part of the NDA's that I've seen and/or been party to expire after a certain time, however, usually five years.
If the breadth of the road is c, normal to its length, then the breadth b of a bus must also be measured normal to its direction of travel. (Thus b is bus width, not length.)
You seem to be mixing up concepts that are unrelated. The photoelectric effect is a quantum phenomenon while antennas, signals and filters are classical.
You may not be aware that there are no room temperature superconductors—yet. Superconductors expel magnetic fields, so one way to tell if you have a superconductor is to place it in a uniform magnetic field, cool it through the transition temperature, and watch the external fields change.

This is correct. A finite sequence sampled from a longer continuous waveform cannot be exactly reconstructed. The energy lost can be calculated by setting up an eigenvalue problem whose kernel is a sinc function (of course!). Eigenfunctions in the continuous case are the prolate spheroidal wave...
