    There's a Roger Zelazny novel where the protagonist inherits a trust fund that supports him so long as he's in college -- so he manages to keep changing his major, and doesn't gradate for over a decade.

    Sounds like my former colleague Domhnuill, except it took "D'ol" only 9 years to graduate. And he didn't have a trust fund, just the student grants. And his main trick was getting elected to full-time student organisation posts (Union President, Representative Council, etc) and only had to pull the "change faculty" stunt twice.
    Eventually the university changed the rules to stop it happening again, but they couldn't change the rules that applied to him (no retroactive legislation). But he accidentally passed his finals one year and ended up in the jobs market.
    I think he's in marketing these days, but he was a reasonably good technician for a few years. Even if he couldn't remember how to calibrate a chromatograph after re-building it.

    We have the capacity to keep using fossil fuels for a couple of centuries still,

    There is significant doubt about this. An article a couple of years ago in "Geoscientist" (the house journal of the Geological Society of London - written by geologists, for geologists, not for laymen. I've just looked, and it appears the article in question predates their content going online.) posed serious questions about the quality of the data collection that leads to claims that "we've got enough coal to last centuries". The same article also applies more statistical techniques to the rather less uncertain statistics of production (Do you want to get into a discussion about the distinction between proven and probable reserves? Arcane and tedious, as well as inherently uncertain.) and produces a talking point estimate that "peak coal" may be as soon as 2030 to 2050, with reserves and production unavoidably tailing off after then.

    Anyway, we're only geologists. What the fuck would we know about rocks and their mining? Let's leave it to the economists to pull a few gigatonnes of coal out of their arseholes. They can do it while pissing oil and spouting bullshit.

  4. would anyone volunteer to go on such a trip? on Sending Astronauts On a One-Way Trip To Mars · · Score: 1

    Valentina Tereshkova (the first female cosmonaut) is on record as saying that she'd take the one-way trip.
    If I thought that something useful would come out of it, I might volunteer ("something useful" being one caveat ; details of scheduling being another). But I think it's really a false dichotomy.

    No, I haven't RTFA. but I've enough respect for Lawrence Krauss to expect that he's addressed this point. Oh FSCK it, I'll just RTFA ...
    Krauss makes good points, but to my mind the more significant problem is going to be that of the travelling. As Krauss says, the biggest problem is the in-flight radiation. And the only effective solution to that is mass. Which slows travel times (because it required energy for acceleration. So, one way or the other, we're going to have to get used to long, slow trips in massive space craft.
    Once you've decided that you're going to go down that route, the future becomes clear : use robotic craft to put a solar-powered engine onto a medium-sized comet ; put the comet into earth or lunar orbit ; carve off chunks for shielding and reaction mass, to go off hunting more comets/ asteroids.
    In the interim, you've got to develop the technologies of living in a closed environment to the point that you can close the ecology for a trip of a few years, with people on board.
    Once you're there, technologically, sending an exploration party on a 10-year round trip to Mars is just a high-tech space-borne latter-day version of the voyage of the Beagle. (Which made Charles Darwin's scientific reputation, for those who don't get the reference.)

    No, it's not a risk-free option (IIRC, a couple of the Beagles sailors died in accidents and or disease). But life isn't risk-free.
    Oh, and incidentally, if the Beagle-3 happens to hear of an asteroid sterilizing Earth while they're away ... well, they're already equipped to last another decade or so, so they've got a good deal of time to improve their technologies.

    By the time that we can do a multi-year trip to Mars (one-way or two way), we'll be good enough at living in space to not need to worry about it being a one-way or two-way trip. The biggest remaining problem would be getting a return-to-orbit craft onto the ground. And that can be done robotically, until we're confident of the technology. Hell, land three return-to-orbit craft and use them to hold down the corners of the habitat.

    To demonstrate that this is an issue, you'd have to provide evidence that free-balling men have a significantly higher fertility on average than non-free-ballers. Journal, volume and page please. (It's not that I don't believe that you're probably correct ; but I do doubt that the effect is powerful. Particularly since the temperature difference between balls hanging free in space and balls hanging in a pair of trousers is not likely to be large. "Significant" is the word.)

    I've never heard this before. Citable evidence please.
    Further, it's decidedly implausible as discussed after your next point.

    It's been years since: perhaps NASA has learned some lessons to ease the problems, but hormonal swings of any sort among very busy, very overworked astronauts is asking to waste a lot of time and a lot of taxpayer money.

(That word again!) So I think, simply on that basis, that it's unlikely that they'd have sent a woman up who was about to have her period.
    Again, that's if they thought that it was likely to be significant. OK, B a l e n t i n a _ T e r e shh o v a _ _ was the first, so maybe they wouldn't have known. But if it had been a discovery, then there is likely to have been mention of it.

    Would they not have known about the possibility of excessive bleeding, presumably as a result of the high G of the descent? To quote the Wikipedia page, "Training included weightless flights, isolation tests, centrifuge tests, rocket theory, spacecraft engineering, 120 parachute jumps and pilot training". So, do you seriously think that the Russian army/ air force/ paratroop forces are unaware of the consequences of multi-G loads on the delicate female anatomy at that time of the month.
    Being married to one Russian lady, and having worked with several others, I find the concept of them accepting (let alone asking for) some sort of special consideration for being a delicate little lady ... well, I'd rather that you put your balls into that particular spike-jawed vice ; I may not particularly attached to mine, but I foresee pain as the lovely little ladies realise what you're trying to suggest. Being female and being feminine does not mean being personally soft.

    But, as far as I understand it, our abilities at finding exoplanets are generally limited to large Jupiter-sized planets with shorter periods.

    You're not wrong, but you are being too ... restraining.

    True, the majority of the tools that we use, at the moment, for detecting exoplanets are tools that are biased towards finding large planets in close orbits, but that is changing slowly for several reasons.
    Firstly, the most effective technique (so far) relies on gravity to agitate the star in the line of sight ; this is obviously biased to detecting large planets (because they have a lot of gravitational mass) ; it is less obviously biased to stars of small mass (for the same reason) ; it has an implicit bias towards close orbits because a close orbit (short orbital period) gives a lot of repetitions of the signal in a short period of observation, allowing for lots of measurements of the spectrum at different phases, between re-calibrations of the spectrometer. Improving spectrometers are addressing the mass biases ; longer epochs (duration from start of measurement series to end of series) of observation are addressing the period bias.
    (This technique also has an orientation bias - a brown dwarf of 14Mj in a 23 hour orbit around (say) Proxima Centauri (closest star to the solar system) which is orbiting perpendicular to the line of sight would remain invisible to this technique for a long time to come. Let's call this hypothetical end-case "Sisimen" for convenience.)
    Another technique that is becoming common, and is likely to unleash a flood of data in the next couple of years, is simple occultation. This has biases for a large ratio of planetary diameter to stellar diameter (to give a high ratio of occultation), short periods (lots of repeated events to stack and improve the signal-noise ratio), and orientation to line of sight (related to the ratio of occultation). Still real biases, but appreciably different to the spectrometric biases.
    ("Sisimen" would also remain invisible to this technique.)
    The same technique has been applied, with lesser sensitivity, to large clouds of stars as part of the "MACHO" observation project of the last decade or so - I wonder if they have any possible targets that the French COROT satellite telescope is slated to observe?
    What other techniques are in the pipeline? I can't think of any off-hand, but I haven't done any research on this, so there may be other techniques in proposal. Which will have their own biases, but which biases will be controlled and where possible adjusted to differ (in detail) from the biases of existing techniques. It is a definite aim to extended the search for exoplanets to wider areas of the "M.sin(i),P" parameter space.
