Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment Separation of radio frequency
The question obviously intends you to assume the transmitters are coherent, otherwise they wouldn't create a stable interference pattern.

comment Rigid rectangle in Schwarzschild
Can you clarify what you're asking? Do you want your rectangle to have sides that are geodesics, or are you asking what the coordinates of a rectangle constructed in flat space would be in curved space?

comment What is the notion of a spatial angle in general relativity?
Locally spacetime is flat and you can measure angles just as Euclid did. I don't see the problem with calculating the worldline of the outgoing photon. Why is this hard?
