To Boldly Twitter…

From Dr McCoy to the Real McCoy.  Another Space Shuttle mission has just launched from Cape Canaveral.  They’re off to the Hubble Telescope.

Atlantis on the pad, ready for STS-125


Two astronauts have the twittering bug.  Mission Specialist Mike Massimino is on Atlantis, while Mark Polansky is the commander of STS-127.   Earlier this year, their colleague Sandra Magnus posted a blog from space.

Thus, right before dawn there is total black and as you look out the window it is as if neither the Earth nor the heavens are there. You just exist, floating in an endless sea of black with one bright light, the sun, illuminating the way. Nothing beyond the light exists. It only lasts a moment, though, as the sun rises higher over the nearing horizon. The Earth starts to pick up some of the rays at last and reappears out of the darkness awash in a faint gray color. Drawing closer you can notice that any high clouds in the atmosphere glow orange or red as they too find the morning sun. It is possible to see the terminator as you cross it. The grey of dawn gives way to the bright blues and whites of day that are so distinctive of our water planet. Looking back in the direction from whence you came, the darkness of night is still noticeable. Only looking forward does the day shine clearly. Soon the night is gone as the Space Station continues on its never-ending trek across the planet. The heavens are now just a dark velvety curtain against the brilliant colors of Earth. No stars are visible. They are there, though, waiting for the night which will come in another 45 minutes or so, to show themselves again.

Lovely.
Anyway, Godspeed Atlantis.

Update

Goddamit! Yet again, I was let down by the online streaming video, crashing as loads of people logged on at the last moment. It happened with STS-116, and it happened with the PopeCam.

On Stars

Via Michelle, I hear that 2009 is the International Year of Astronomy.
This seems a good opportunity to post a link to the Light Cone RSS Feed:

From the moment of my birth, light [that I could have influenced] has been expanding around the Earth and light [which could influence me, from an increasing distance of origin] reaching it — this ever-growing sphere of potential causality is my light cone.

Not quite a Total Perspective Vortex, but still awesome (in the old sense of that word).
Elsewhere, the Boston Globe’s fantastic Big Picture blog recently ran an advent calendar of photos from the Hubble Telescope.

ATLAS Hadronic endcap Liquid Argon Calorimeter

ATLAS Hadronic endcap Liquid Argon Calorimeter


The Large Hadron Collider at Cern is being switched on tomorrow. Stephen Hawking says it is safe, and that the machine will not create a black-hole that will suck the entire world in on itself. It is the perfect Douglas Adams scenario. We could all be anihilated by ten past nine tomorrow morning, and no-one will bring the milk in.
Can you imagine just how embarrassing such an event will be for humanity? One moment, we are daring to behold the secrets of the universe, edging closer to the mind of God. The next, we are all squashed, star dust again – only this time, your base materials will be blended with those of your office colleagues and that beige laser printer on the filing cabinet. Perversely, it might actually be the one moment where human beings discover a true understanding of one another. Six billion people united in a single thought: “Whoops.” Perhaps that moment will be worth it.

Against the Windfall Tax

Like Conor at the Liberal Conspiracy, I can’t really get behind this clamour for a windfall tax on oil companies. I would love to have a dig at Big Oil, but something grates.
Its not that I am like Tim Worstall, who has barrels of faith in the market to sort the problem out fairly. Oil extraction and distribution is a sort of cartel, not a free market. In any case, such a market takes time (maybe measured in decades or centuries) to do its ‘thing’, and in the meantime it is probable that excess profits will accumulate while everyone else is suffering from a recession.
No, my problem is that arguing for a windfall tax is surely another way of saying that you want to change the rules retrospectively.
Economists often argue that to change the rules, and to impose a windfall tax, simply breeds uncertainty in the market, and cause the oil companies to under-invest. Its an irritating argument against taxation, because it has an air of a threat about it: “don’t tax us, or we will mess up your economy”. In the case of a windfall tax, which everyone (even the oil companies) assumes will be a very rare occurrence, it is less believable than (say) the case of top-rate tax-payers. So I can see how the campaigners might discount this economic argument.
But leaving aside the economic risks that a windfall tax entails, surely changing the rules is simply wrong wrong wrong, no further discussion required? Imposing some kind of law (in this case, a tax law) retrospectively is the stuff of wild-eyed dictatorships, surely. Windfall taxes are short-cuts. An easy, lazy solution to a complex situation.
Play by the rules… and if you feel you must change the rules, do so only at the start of the game. If we percieve a problem with the way our country operates, its fine to legislate so that it doesn’t happen in the following tax year. Nationalise the oil companies if we must, or tax them at 99%. Whatever. Only this: we must to legislate for the future, not the past.
There’s a familiar saying, which goes something like “you can judge a society by the way it treats its most vulnerable”. Well, an alternative might be that we should judge ourselves by how we treat our most despised. The oil giants are certainly some of the most resented institutions in the country, but to subject them to anything other than the rule-of-law is not, I would suggest, cricket. Compass should leave the oil companies with this year’s profits, and get busy lobbying for a law that would redistribute future profits. That’s the right way a democracy should approach this problem.

Update 3rd September

The only counter argument that has piqued my interest has been that a large portion of the oil companies profits have arisen because of preferences in the system of allocating carbon credits via the European Emmissions Trading Scheme. However, while this is a definite argument for going after excess profits, I’m not sure it justifies doing so retrospectively, as a windfall tax would.

Embryo Research Bill II

My second point about the Embryo Research Bill controversy is one of irritation.  The issue of whether Gordon Brown should have allowed Labour MPs a free vote was portrayed in the media as a battle between the Prime Minister and the dark forces of Catholicism.  Cardinal Cormac Murphy O’Connor vocally insisted on a whip-less vote.
In the binary world of most political reporting, the result of this was that taking moral issue with he Embryo Research Bill was seen as the preserve of Catholicism. However, it is perfectly possible for atheists to have moral objections to the Bill too. The idea that morality can only derive from revealed religion is a great meme that needs to be challenged. The idea that atheism and secularism can be equated with the cold, amoral march of science is equally bad, but its a connection that Cardinals and Popes keep making. They should be challenged on this point.
