    SCHOOL BUSES.

    Whatever happened to walking (or cycling) to school? In the 13 (14?) years that I was in primary and secondary education, I think I got a lift to school on maybe three or four occasions - when Dad had some business to do in town rather than in the factory. And when I was at university, it was either walking or cycling to the department and once per week out on field work.

    Shielding of 4.41 tons/m^2 [nasa.gov] is sufficient.

    Hmmmm, My fist estimate on this sort of this is to look at the Earth's atmosphere. Living at the bottom of the atmosphere is good enough for a lifetime's shielding from interplanetary radiation. One atmosphere is equivalent to 10m of water depth (consult your diving manuals). That's 10 tonnes per square metre of protected area. Half of that amount - sounds reasonably credible. What material to use? Well, air is evidently sufficient (see "lifetime" above). Water is convenient - you'll need a considerable quantity any way. Some metals for taking out the slowed down and secondary radiations. But you'll need be needing metals anyway. I'd probably let the outer parts of it freeze to ice, for a degree of micrometeorite protection, and for the same reason you'll want several layers of it.

    While I'm not exactly a fan of Big Pharma, I can't for one second believe that they'd be so mind-bogglingly stupid as to actually do something like this deliberately.

    An essential step in profiting from this sort of scare would be in letting the general public know about it, to generate an increase in voluntary (re-)vaccination rates. This story is the first I've heard about it, and there's no sign of the story on the BBC news site. So, no publicity means no increase in booster sales.

    Anyway, I had my booster several years ago - due to travel in nasty parts of the world. Not concerned here, despite travelling to the Low Countries on a regular basis.

    Part of the point about only being able to renew a few weeks before the end of the year was to prevent people from driving around for extended period without having an MoT. Insurance too. you had to produce a valid insurance cover note and MOT along with the log book when you renewed at the post office.

    I'm not sure how the online thing works - you'd probably have to plug in the MoT test certificate number and your insurance policy number. But it's been that long since I did that, I don't actually know.

    But on the technological horizon, there's altered graphene based desalinization. It may be possible to efficiently generate drinking/farming water from the oceans, which will end this problem.

    Which ocean are you going to take your water for desalinisation into the Aral Sea area from? The Indian, Arctic, or Pacific? (I wouldn't waste time trying to take it from the Caspian, Black or Mediterranean seas - the Caspian is already isolated and you'd just move the problem ; and the others are at the far end of literal bottlenecks at Gibraltar and Istanbul. Same argument for Persian Gulf and Hormuz)

    Most people waste an inordinate amount of time on "um" and "errr" ; planned public speakers excepted, which is why they charge a significant fee. That's also why the ability to make a presentation in front of a meeting/ classroom, whatever is worth a significant chunk of your salary, if you can do it.

    contrasting levels of religous belief between scientists in the UK and India. It's almost as if atheism is irrelevent to pursuing a career in science

    I note from the figures cited up-thread that religionism amongst Indian scientists was given as 32% (compared to 12% in the UK). Given that general levels of religionism in Indian society are higher than in the UK, that suggests, quite strongly, that being a scientist strongly correlates with a lower than normal (for the society) degree of religionism. Or that going into science strongly selects the less-religious people in a society.

    Right away you are ignoring the definition of deity completely. Notice also that you neglected the definition of a soul,

    Why do you keep bringing a soul into a discussion of atheism? The two are separate things.

    Consider a universe ; it has no life forms, just dead chemistry Nuclear fusion, silicates, ices. That's it. Nothing else. No life. Nothing conscious or even self aware. An atheist position on such a universe is that there is no supernatural deity in that universe. Whether there are any souls in that universe is completely immaterial to that question.

  13. Re:Um, no! on Are the World's Religions Ready For ET? · · Score: 1

    A soul, and judgement system for a soul, does not meet atheist criteria of a deity-less universe.

    Speaking as an atheist, and also a non-believer in souls, re-incarnation and an afterlife, I don't think you're right.

    Without recourse to science fiction, I can envisage, within a century or so, the transfer of minds into computing systems. If that works then you've moved a non-corporeal entity (your consciousness, your memories, your personality) from one body to another. If that's not, functionally, a soul, an afterlife and re-incarnation, then I don't know what is. But that wouldn't stop me remaining an atheist.

    There's still no need for a god of any sort.

    The specific question is about extra-terrestrial life forms - and not necessarily intelligent ones.

    The book in question is more about the existence of extraterrestrials anywhere in the universe, being detected by astronomical observations. Whether or not the ETs actually come here to visit us (and we're not going to visit them for centuries at least) doesn't seem to be an issue that the summaries address, or even consider important.

    As a scientist (geologist), I know I have no data on the presence of life (or even intelligent life) on other planets, yet. But we do know that interstellar transport is not an easy problem, so the probability of intelligent life AND interstellar transport is going to be considerably lower than just the probability of intelligent life on it's own.

    That's invasion or illegal landing of an illegal immigrant. If someone tried dropping (say) a Mexican on an island off the coast of America, you'd count that as an illegal immigrant being landed, which would result in the arrest of the landed person and the seizure of the vessel assisting the illegal immigrant.

    Your thought experiment isn't well thought out. Try running it again in the Great Salt Lake, as I said up-thread. The Kara Sea is surrounded by Russian-occupied islands. Everything in it is as Russian as any islands in the Great Salt Lake are American.

    I work in exploration of the continental slopes (there's a damned good reason for my vessel to have holds capable of carrying 3km of riser pressure-rated to 20kpsi). It's on-going. Unfortunately the costs are much higher than for exploring, developing and producing in shallow water, which is why only the highest-quality prospects are worth developing.

    Unless you believe Tom Gold (which would get you laughed out of any board room with a geologist in it), you need sediment in considerable quantities to generate significant quantities of hydrocarbons (note below). After which, looking at your hypsographic curve you'll see that the 5km water depth contour (OK, "isobath") encompasses something slightly less than 5% of the Earth's surface while the average depth of the oceans is 3800m.

    And now you know why the commercial vessel I work on (one of 4 sister ships, built to the same basic design) has space for 3km of marine riser, and the largest vessels on the slipways of China only carry 5km of riser.

    Some early explorations were discouraging, but MOST exploration is discouraging.

    In intensely planned remote area deep water offshore exploration, the discovery rate is about one well in three.

    I was discussing a previous well with another vessel's weather forecaster (that'll tell you which region we were in) who informed me that core was brought to the surface on three occasions which was oozing with oil; my geological sources refused to comment (quite correctly) several years later when I quizzed them about it, which I take as confirmation. A discovery! Yes. The prospect and regional license was abandoned. The discovery wasn't big enough to have a chance of repaying the billion dollars poured into finding it.

    Welcome to offshore exploration.
