    Undergrad Solving Riddle: Find Closest 2 Points on a Plane in O(N)

    I know there's a so-called "simple" solution that requires O(N * log^2(N)), and a more complex one that requires O(N * log(N)).

    Undergrad Solving Riddle: Find Closest 2 Points on a Plane in O(N)

    Here's a riddle I'm having trouble solving: There are N points on a plane. Find the two points that are closest, in time better than O(N^2). Any idea? Thanks :)

    Building a low-energy microwave generator.

    I want to build a low-amplitude microwave generator. Nothing as strong as in real microwave ovens. I believe I have most of the theoretical knowledge needed, and I am willing to spend up to 200$ on materials. Any idea where to start? Anyone tried this himself once? Thanks :)

    High School A couple of basic questions about electromagnetic waves

    Hi, I'm new. From what I understand, radio waves are generated these days using alternating currents or mechanically moving charges. The highest frequencies that modern technology reaches is somewhere in the bottom of infrared. Theoretically speaking, is it possible to emit visible light...
