  • Separate sound and video of an mp4 file.?

    I'm trying to watch a video but at some point along the picture freezes for a few minutes and the sound keeps playing, which of course puts it out of step with the picture once it resumes. My question is is there a means or some software which could separate out the sound a picture so I could cut out the frozen part, or will I have to use a program like Audacity to record the sound as it plays and then cut the video and somehow recombine them?

  • In python, how do I save a defined function for future use?

    If I define a simple function, like printing all the square numbers up to n or whatever, is there a way that I can save it so that next time I start up Python, I don't need to redefine it and can run it straight away? If so, how?

  • Can you stimulate alpha radiation?

    Given that alpha particles exist in a potential charge well in the atom such that they can only escape by tunneling, would it be possible to input energy into an alpha emitter such that rather than tunneling out, the particles can simply go over the top of the well and escape according to classical means?

    I know my explanation and terminology here isn't fantastic, and my knowledge of potential wells and tunneling is a little limited, but would this be possible?

  • Can light travel faster than the limit imposed by the medium?

    Say, for example, is it possible for light to travel at the full ~3*10^8 m/s in water? And if so, does anything in particular happen like some radiation being given off, or the water being ionised, or some such thing?

  • What happens when the products of a vacuum fluctuation get separated?

    Ok, having learned about vacuum fluctuations (and please correct me if I'm wrong on this), in a vacuum, a photon can 'cease to exist' which transfers its energy to create, for example, an electron-positron pair, but they can only exist for a limited time because of the uncertainty principle, and they soon annihilate.

    My question is, what happens when, for example, a fluctuation occurs just outside the event horizon of a black hole, and one particle, but not the other, is taken into the black hole and destroyed, does it violate the uncertainty principle? The way I see it, there's a particle which should only exist for a short time, but its counterpart which it needs to cease to exist, has been destroyed. Does the particle just disappear of its own accord after a time? If another fluctuation occurs to create an (anti)particle to annihilate the first, then wouldn't one be left over anyway, and the same issue arises?

  • Is it actually possible to prove that 1 + 1 = 2?

    I mean without simply relying on the fact that it does. If so, it seems like a quirk of the subject that the science where everything must be completely proven relies on a fundamentally unprovable concept.

    Also if it is provable, putting the proof here would be great if it's concise enough

  • Pocket watch hinge pin sticks out?

    The pin holding the cover on one of my pocket watches seems to work its way out of the hinge over time when opened and closed (see pic). I was wondering if this is a common problem and if there's a way to fix it permanently rather than just having the watch shop hammer it back in every so often. The design on the cover makes the cover irreplaceable. Could anyone help me with this?

  • Pocket watch battery change help?

    I'm changing the battery on a quartz pocket watch, and I've managed to pop off the back cover, but part of the plastic which holds the movement in place covers the battery (image below). None of the assorted guides on the internet seem to list this issue. I'm asking what should I do to remove the battery, or is it set up so that the battery is non-replaceable?

  • What do you think of this definition of insanity?

    I'm wondering whether this seems to make sense to people. It is probably more religion based, but I think this is a better section to ask than R&S.

    It's quite common to see people claiming that believing in the illogical and irrational is insane, but that's not entirely true. A lot of new scientific discoveries seem illogical until they are fully explained, you only need to look at quantum physics from the perspective of a classical physicist to see that, but insanity is wanting to believe in the irrational. Believing something that makes no sense is not insane, but being given a logical and rational explanation of a phenomenon, and then choosing not to believe it, that is insanity.

    I was just wondering if that makes sense to you guys or if it was just me.

  • Question about Blood Groups?

    Is it possible for two parents in the B+ blood group to have a child in the O+ group? Just I recently got told I was O+ when giving blood, but both my parents are B+, is this possible through recessive traits being passed on or is it possible that the blood donation people made a mistake?

  • Question about omnibenevolent gods...?

    Ok, firstly, I'm not trying to pick on any religions or troll or anything like that. This is a valid question.

    You see, the thing I don't get about religions with omnibenevolent and all-loving gods (Christianity being the most prominent example which springs to mind) is that it easily loses some credibility because it's not difficult to find flaws (like 'Why is there evil in the world?' or 'Why isn't the world perfect?') whereas if you were to look at, say, the Greek/Roman Pantheon, you get a lot of whimsical gods who don't really care for humanity without reason and who could turn you into a cow just to hide you from his wife (this example being Io), and it becomes slightly harder to point out immediate faults in reasoning.

    What I want to know is why/when did religions with omnibenevolent gods become more prominent than than that of whimsical gods? I know that you can take comfort in supposedly being loved by an omnipotent being, but surely there must be more than that.

  • What would happen if a proton and an antineutron collided?

    On the assumption that hadron annihilation is down to quarks meeting antiquarks, if a proton, (up up down) collided with an antineutron (antiup antidown antidown) would one up annihilate with the antiup and the down annihilate with an antidown, leaving 2 quarks which would form a positively charged meson? Would the remaining quarks just fly away in opposite directions? Or would nothing happen, and if so, why?

    As is also true for circumference and area of a circle, but not of any other 2D or 3D shape I can think of. Why is this?

  • What's with all the stereotyping in the politics section?

    I keep seeing things such as "demoKKKrats" everywhere. You're complaining about intolerence while being intolerent, and that's not the only example of it.

    You guys are worse than the R&S section.

  • If God falls over in a forest, and there's noone there to believe in him, does he make a sound?

    Doesn't necessarily have to be in a forest, but I guess it's as good a place as any.

  • Binary Star Systems Concept..?

    As a concept, could a planet or small satellite exist in a relatively staionary position between 2 stars in a binary star system in a sort of gravity equilibrium. This is assuming the force of gravity from each star is pretty much equal and pulling in opposite directions. Also I know that it is possible for planets to have a 'figure-8' orbit which goes around and between the stars, but I mean for it not to have an orbit at all or for it to at least not to leave the area between the 2 stars. I know that this is unlikely, but it's a big universe. Could it be possible?
