A decade closes; a decade opens

The new millenium opened when my son Matthew set off a firework that soared into the sky at a New Year's Eve party, almost exactly ten years ago. We stood out in the road and listened to the roar and crackle of fireworks exploding all over the neighbourhood. The first decade of the new millenium ended sitting quietly on the sofa next to my wife; the kids off at different social engagements of their own. It has been a rollercoaster of a decade; the first two years struggling to complete an external PhD on time (eventually successfully submitted in Jan 2002). The highlight was passing the Viva exam, then flying back from Edinburgh to Heathrow on a brilliantly sunny July day, landing at Heathrow, and being given a magnificent view of Concorde, just landed as we taxied in from the runway. It seemed almost as if this magnificent view was the cherry on the icing - the sense of triumph was palpable, and highlighted by the view of the beautiful aircraft. Since then, a rollercoaster as

Prejudiced against prejudice

Any deep philosophy tends to get rooted in paradox – the paradox itself providing the motivation to explore further, like the irritating bit of sand in the oyster shell that won’t go away and gives rise to a beautiful pearl. Here’s a good example from Socrates, after being attacked by a politician late in life: “I am wiser than this man; it is likely that neither of us knows anything worthwhile, but he thinks he knows something when he does not, whereas when I do not know, neither do I think I know; so I am likely to be wiser than he to this small extent, that I do not think I know what I do not know” A more pithy version along the same sort of lines also from Socrates is: “The one thing I know is that I know nothing.” Socrates taught by active dialogue with pupils and not by written word. I imagine that if Socrates had a blog, his entries would be short and terse (unlike this one), and the comments session would extend to a much greater degree. If I were in discussion with Socrates,

The Sims and Evidence

Computer Simulation Games and Scientific Evidence In this post, I shall carry on my discussion of the nature of miracles and the demand for scientific evidence, using as a model the computer game The Sims . In order to do science we have to make observations in order to gather evidence, formulate theories based on the observations we have made, and then make predictions from those theories.  We postulate experiments that will confirm the correctness of our theories if the outcome is in line with our prediction, or will falsify the theory if the outcome differs from the prediction. That's what science is.  Anything that doesn't follow this pattern (evidence, prediction, validation or falsification), but allows literally anything to be explained away isn't scientific.  An example is given in an A-level Psychology textbook about philosopher Karl Popper's criticism of Freudian psychoanalysis as being unscientific: Science is supposed to deal in observable evidence, but psyc

Christ in the Universe - a poem for Christian Trekkies

Gene Roddenberry, the creator of Star Trek, had a vision of a galaxy teeming with intriguing alien life forms that it was the Enterprise's five-year mission to seek out. In successive Star Trek franchises the spiritual beliefs of these alien species were often investigated. It seems Roddenberry was preceded in this idea by Alice Meynell (1847-1922), an English Catholic mystical poet, who wrote the following marvellous poem in 1917. Christ in the Universe With this ambiguous earth  His dealings have been told us. These abide:  The signal to a maid, the human birth,  The lesson, and the young Man crucified. But not a star of all  The innumerable host of stars has heard  How He administered this terrestrial ball.  Our race have kept their Lord’s entrusted Word. Of His earth-visiting feet  None knows the secret, cherished, perilous,  The terrible, shamefast, frightened, whispered, sweet,  Heart-shattering secret of His way with us. No planet knows that this  Our wayside planet, carryin

Simulation games, miracles, and why Dawkins is wrong

I recently listened to a debate between the foremost "New atheist" spokesman Richard Dawkins, and Oxford Mathematics professor John Lennox, who is an evangelical Christian. Dawkins led off in his typical manner, attempting at the outset to ridicule Lennox for believing in miracles. Doubtless this will give Dawkins acolytes much to cheer about; though it is difficult to see how it is constructive dialog offered by a human being interested in rational discussion. He started by saying that he was accustomed to debating with "sophisticated theologians", (presumably ones who don't believe in miracles) but in Lennox, he had found a scientist who believed that Jesus turned water into wine. He outlined what this entailed - that somehow Jesus had interacted with the water molecules and added proteins, carbohydrates, tannin and alcohol to it. This, and other beliefs (such as walking on water, dying for our sins etc), he stated were "profoundly unscientific".

We call this Friday God

The wounded surgeon plies the steel That questions the distempered part Beneath the bleeding hands we feel The sharp compassion of the healer's art Resolving the enigma of the fever chart. Our only health is the disease If we obey the dying nurse Whose constant care is not to please But to remind of our, and Adam's curse, And that, to be restored, our sickness must grow worse. The whole earth is our hospital Endowed by the ruined millionaire, Wherein, if we do well, we shall Die of the absolute paternal care That will not leave us, but prevents us everywhere. The chill ascends from feet to knees The fever sings in mental wires. If to be warmed, then I must freeze And quake in frigid purgatorial fires Of which the flame is roses, and the smoke is briars. The dripping blood our only drink, The bloody flesh our only food: In spite of which we like to think That we are sound, substantial flesh and blood - Again, in spite of that, we call this Friday good. I have just typed by hand

Keep religion and philosophy out of science lessons, Prof. Dawkins!

I've just finished watching the Royal Institution Christmas lecture series for 2008, which was televised last week in the UK. This is a long and venerable lecture series, dating back to 1825 when the first series of lectures were given by Michael Faraday (see here for a list of all the lecturers). I myself attended the lectures in 1969 (Prof. Sir George Porter on Time Machines) and 1970 (J. Napier on evolution). The lectures are primarily aimed at schoolchildren from the ages of 11 onwards. Many eminent scientists have given these lectures before, including both holders of the post of Professor of Public Understanding of Science, Richard Dawkins, and the current holder, Marcus du Sautoy. This year's lectures were of special interest to me as they were given by my PhD supervisor, Chris Bishop, who is head researcher at Microsoft Research in Cambridge. In one of the lectures, Bishop gave an amusing demonstration of the precision of the laws of physics; saying that the small
