2 more questions, if I may: 1. Should I trust a device like the one at the link? 2. Isn't there any substance that can absorb microwaves and this way act as a protection? Thank you very much! I appreciate your help!

Thank you for your prompt and informative response! Unfortunately the police in my country is not as useful as you may expect so I really doubt that informing them would help, but thank you for the suggestion. I'll my friend about it. Is there any, not very expensive, way to detect such waves...

Is it possible to injure your neighbor with microwaves using the heater of a microwave oven when there is a thick wall yours and your neighbor's apartments? I know this is a really weird questions, but that's because it's related to a really weird situation. A friend of mine does not get along...

Thank you very much HallsofIvy, that's really helpful!

That's great! I'd love know what would be that equation. I found the following: In an x-y coordinate system, the circle with centre (0, 0) and radius r is the set of all points (x, y) such that: {x}^2+{y}^2={r}^2 But I'm not sure how to find the coordinates of a random point using this formula.

Hi. If the radius of a circle is known and it's also known that its center is at X:0, Y:0, how can the points that form the circle be calculated? What would be the coordinates of a random point of the circle? I made a simple illustration hoping that it would make the question a little clearer...

Perfect. Thank You.

Hi. This is the first Topic I've posted at (the very cool) Physics Forums site so go easy on me. My English is very far from perfect so some used terms may not be used correctly... :) Anyways... I was writing a script for a website and a mathematics question popped up. The numbers 1...
