coincidence Definition and 54 Threads

EK = mv^2 energy kinetic = mass times velocity squared So... Isn't one way to interpret time dilation that everything moves through time and space with a sum velocity of c (somehow), and that as velocity in space increases velocity in time therefore decreases? I've read this in several...

Some my puzzles of “coincidence counting” When I read literatures concerning with two-photon interference experiment, the “two-photon interference patterns” are always got by means of so called” coincidence counting”. My questions are: What is the coincidence counting? What the essential is the...

Our sun eminates electromagnetic radiation over an enormous range of frequencies. Radiation curves (energy@wavelength) resemble bell curves, and highly accurate measurements have shown that the peak of the sun's radiation curve is in the visible light range. This is not a coincidence, it is...

I have met people who believe magic of mathematical coincidences magnified by their own predisposition for patterning. A TV commercial will say the word "soap" simultaneously to the viewer (me) thinking it. Perhaps you, at a party, were about to say the word "hippopotamus," but suppressed the...
