  • I’ve known a lot of math people, and /on average/ I think they’re more capable of programming useful code than the other college graduate groups I’ve spent a lot of time working with (psychology, economics, physics) /on average/.

    That said, the best mathematicians I’ve known were mostly rubbish at real programming, and the best programmers I’ve known have come out of computer engineering or computer science.

    If you need a correct, but otherwise useless implementation, a mathematician is a pretty good bet. If you need performance, readability, documentation, I’d look elsewhere most of the time.


  • We have only a single advanced civilization to use as a comparison point for the strength or our telescopes, and that’s ourselves. From my understanding of it, the most powerful broadcast we’ve made out is 15-20MW for an over the horizon radar system, and that only ran for 40 years or so. I don’t have an exact answer, but my understanding is that even for our largest radio telescope, 20 megawatts at a distance of 100 lightyears would be below the noise floor.

    Nuclear tests are slightly more visible than that, but only occur periodically, so you’d have to have a telescope facing the right way by coincidence. Basically, if there’s an Earth-like civilization 200 lightyears away, I think we would be entirely blind to it, and that’s over a tiny distance in the scheme of things.

    The farthest known exoplanet is 27,710 lightyears away, and was discovered by the transit method - but this was made possible because the planet is very big (bigger and heavier than Jupiter), and orbits quite close to its star (with a 43 hour orbit). To be detectable at that range, a signal has to be stronger than some stars are bright.
