    Why does sound travel further at night?

    Like, when there's no sun around to photosynthesise?

    The Doppler effect

    So if I'm standing still, the wind is blowing from the south and there's a sound coming towards me from the north, will the sound travel faster, relative to me, or slower? If it's constant through the medium, and the medium is pushing the source away from you, what do you reckon?

    The Doppler effect

    What if the medium is moving? Then the speed is still constant through the medium.

    The Doppler effect

    That's what I thought, but robzy disagreed with me. The speed is constant through the medium. (For the purposes of a physics question)

    Less ambient noise.

    There's a cheap curry place here: http://bit.ly/3KTPSs Walk along Melbourne St once you've look at GoMA or the Museum, then keep going along Boundary. That's West End. Where's the thing you're going to?

    I need some help with a puzzle...

    Infinite points on its circumference would infer that it is a curve. A curve is a line that changes its direction continuously from point to point throughout its entire length. I would say it has no sides. "A curve is a line that changes its direction continuously from point to point throughout its entire length" from point to point, huh? so theres a new bearing to each new point, and by deduction, straight lines in between points. how close are these points together? of course, the idea of a "point" is an abstraction, so there need be no limit on how many there are, how small, and how close they are together. but no matter how far you zoom in, you will not escape the fact that there is a theoretical straight line, or "side", between each and every point. however, you might well concede that there is a level of scale beyond which all considerations of 'sides' become meaningless and not applicable to any useful purpose. so, i would not say it has no sides. it is most correct to say it is undefined. Who defines a circle parametrically? The answer is an engineer pretending to be a mathematician.

    Every (Euclidean) polygon has an infinite number of points on its circumference.
