Jim Al-Khalili on nuclear power

Pompey Skeptics' Honorary President Jim Al-Khalili is our next speaker — at the Rose in June PH on Thursday 10 September. Details and tickets (£3.50) from here:

http://www.wegottickets.com/event/329076

Can't wait that long for your Jim-fix? Tomorrow on BBC4 he's presenting a documentary about Sellafield nuclear power station:

http://www.bbc.co.uk/programmes/b065x080
Lying on the remote northwest coast of England is one of the most secret places in the country - Sellafield, the most controversial nuclear facility in Britain. Now, for the first time, Sellafield are letting nuclear physicist Professor Jim Al-Khalili and the television cameras in, to discover the real story. Inside, Jim encounters some of the most dangerous substances on Earth, reveals the nature of radiation and even attempts to split the atom. He sees inside a nuclear reactor, glimpses one of the rarest elements in the world - radioactive plutonium - and even subjects living tissue to deadly radiation. Ultimately, the film reveals Britain's attempts - past, present and future - to harness the almost limitless power of the atom.

No more NOMA, no, no, no.

This evening I watched something my faithful telly-watching machine recorded for me last week — Rosh Hashanah: Science vs Religion, a half-hour programme presented by the Chief Rabbi, Jonathan Sacks.

Lord Sacks is often on Thought for the Day, speaking with his characteristic measured pace, endowing each word with great meaning and authority. His precise enunciation, however, fails to conceal an embarrassing fact: that the meaning and authority are wholly spurious. It's almost as if he strings words together solely based on their euphony, without consideration of what the words might actually mean.

 

"For me, science is one of the greatest achievements of humankind — a gift given to us by God."

Well, which is it, Lord Sacks? An achievement of humankind? Or a gift from God? (Is it any wonder he thinks science and religion are compatible when he obviously can't see the blatant incompatibility of what he's saying right at the start of his own TV programme?)

You have a couple of days to catch the whole thing on iPlayer:

Some clips:

The blurb from the BBC website:
Religion and science are frequently set up as polar opposites; incompatible ways of thinking. The Chief Rabbi Lord Sacks begs to differ. For him, science and religion can, and should, work together. To mark Rosh Hashanah, the Jewish New Year, he puts his position to the test. He meets three non-believing scientists, each at the top of their field: neurologist Baroness Susan Greenfield, theoretical physicist Professor Jim Al-Khalili, and the person best known for leading the scientific attack on religion, Professor Richard Dawkins. Will the Chief Rabbi succeed in convincing the militant defender of atheism that science and religion need not be at war?
It's clear that all three of the atheist scientists to whom Lord Sacks puts his plea are willing to concede that there are limits to science — and that's where the Chief Rabbi jumps in to claim the ground for himself, while simultaneously decrying "God of the gaps". But he doesn't seem to realise that just because science doesn't have answers to certain questions, he cannot claim that religion does. Because it doesn't. All that religion can do is interpret scripture — which more often than not means making stuff up.

My QED 2012 experience — part 2

(Click here for part 1.)

I bought lunch in the hotel bar (I wasn't going to repeat last year's mistake, when a bunch of us decided to eat out — unfortunately on that occasion service was so slow we had to bring our food back with us, twenty minutes late for Jim Al-Khalili's talk on time travel). So this time it was coffee and a sandwich — basic, cheap and quick — and I'd had a good breakfast, plus I was booked in for the Gala Dinner in the evening.

I was looking forward to Ophelia Benson's talk, titled "Silencing for God", as I read her blog Butterflies and Wheels (at least I try to; she's so prolific it's hard to keep up — a point I made to her in a brief conversation the previous evening during the Mixer). Her first example of free speech suppression was from University College London, where there had been some fuss over the use of a Jesus and Mo cartoon appearing on the Facebook page for the university's Atheist Secularist & Humanist Society. The Students' Union claimed this was offensive and demanded it be taken down. The controversy spread to the London School of Economics with similar results, and even further: award-winning young skeptic Rhys Morgan used the cartoon (actually it was the cover of a Jesus and Mo book) as his profile picture as a mark of solidarity with the ASHS, and his school demanded he take it down — on pain of expulsion. These are classic claims of the right not to be offended — which as it happens is not actually a right. Interesting to note that Rhys Morgan and "Author" (pen-name of the author of Jesus and Mo) were both at QED.

Ophelia had plenty of other examples from all around the world, many using intimidation to stifle free speech. The problem is that religions (of many different stripes) believe they have the right to censor the words of people who don't subscribe to the particular religion that's objecting. It's only by standing firm, en masse, that this kind of thing will be defeated — which is difficult when you're faced with what appear to be genuine threats.

Sarah Angliss delivered a talk-cum-demonstration entitled "Voices of the Dead", which included some highly surreal music and a live demonstration (recording as well as playback) of an Edison Phonograph. Weird instruments were in evidence, including what must be the ultimate weird instrument, a theremin, played by waving one's hands at and around it. The instrument on stage appeared to be commercially produced (it had the "Moog" logo on it). Sarah was another speaker I was keen to hear on account of her reference to a temporary exhibition (which I saw at the Science Museum) of the work of Daphne Oram, including the original "Oramics Machine" used for creating electronic music.

Previously I'd only come across Massimo Polidoro in Skeptical Inquirer, for which magazine he writes a regular column. He's been involved in the JREF Million Dollar Challenge, overseeing many attempts to prove paranormal phenomena, both as part of the MDC and elsewhere, none of which has so far succeeded. His talk, "The Search for Superman", documented some of the more unusual and hilarious of these attempts.
DSC_3413_MassimoPolidoro_1DSC_3414_MassimoPolidoro_2

The afternoon concluded with Richard Saunders, well-known to listeners of the podcast The Skeptic Zone, otherwise well-known to viewers of Australian TV. His talk, "The Delights & Dangers of being a TV Skeptic", gave us the inside story on some of the programmes and series on which he's appeared. He also demonstrated the infamous "Power Balance" bracelet, using a not entirely unknown volunteer:
DSC_3417_RichardSaunders_1DSC_3424_PowerBalance_1DSC_3429_PowerBalance_2
The Power Balance story is one of success for the balanced powers of organised skepticism. After several publicised tests and prolonged media exposure the product — shown to be fake — was withdrawn, and the company sold. Unfortunately other bogus woo has promptly jumped in to fill the gap in a credulous market. Eternal vigilance required!

The Gala Dinner on Saturday evening was a success. I didn't hesitate to book for this optional extra, as last year's was definitely worth it, but how successful it is for any individual depends on whose table you're assigned to, and what mix of dining companions you find yourself amongst. After the dinner, Robin Ince introduced the Skeptic Awards, which were followed by a musical performance from Sarah Angliss, including yet another weird instrument — a sonorous saw coaxed into audibility using a violin bow. Then we had laid-back stand-up from Alun Cochrane (superb), and stand-up plus conjuring from Paul Zenon, whose performance with a full beer glass swinging from a string, while walking among the audience, was as surprising as it was scary (I still wonder if he's ever had a serious accident — and concomitant injury claims — as a result of this reckless stunt). It was, needless to say, the cause of much nervous hilarity.

The night apparently continued with dancing late into the early morning, but I needed some sleep.

Prof. Steve Jones on The Life Scientific

Today I listened to a delightful conversation between Jim Al-Khalili and geneticist Steve Jones, on the former's BBC Radio 4 programme The Life Scientific. It's over a week since it was broadcast, but all episodes are available as mp3 downloads from the BBC website. I've seen Prof. Steve Jones "in the flesh" a number of times — first as part of last year's Uncaged Monkeys tour at the Basingstoke Anvil, and more recently at this year's QED, after which he stepped in to introduce his former pupil Adam Rutherford when he gave the Darwin Day Lecture at Congress Hall in London.

This half-hour conversation is a low-key affair, with many insights into what it's like to be a research scientist. Steve Jones made a surprising point about mediocre science being worthwhile despite its mediocrity. There were also comments from Jerry Coyne, with whom Steve Jones worked. Fascinating stuff.

The Secret Life of Chaos

I watched this one-off documentary yesterday (it was rebroadcast earlier this year, and it's taken me a while to get round to watching it again). Jim Al-Khalili explains how we get complexity from simplicity, and as far as abiogenesis is concerned the implication is clear. It makes "intelligent design" a superfluous theory.

The hour-long documentary is no longer available on iPlayer, but there's a dedicated webpage with several clips, and with luck it will be rebroadcast yet again. (It was apparently available on YouTube for a while, but all instances appear to have been removed.)


Here's the blurb from the BBC website:
Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. 

It turns out that chaos theory answers a question that mankind has asked for millennia - how did we get here? In this documentary, Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science - how does a universe that starts off as dust end up with intelligent life? How does order emerge from disorder?

It's a mindbending, counterintuitive and for many people a deeply troubling idea. But Professor Al-Khalili reveals the science behind much of beauty and structure in the natural world and discovers that far from it being magic or an act of God, it is in fact an intrinsic part of the laws of physics. Amazingly, it turns out that the mathematics of chaos can explain how and why the universe creates exquisite order and pattern.

And the best thing is that one doesn't need to be a scientist to understand it. The natural world is full of awe-inspiring examples of the way nature transforms simplicity into complexity. From trees to clouds to humans - after watching this film you'll never be able to look at the world in the same way again.
Inspiring stuff.

Everything and Nothing — Professor Jim Al-Khalili

We've had Professor Brian Cox's latest wondrous TV series ogling different aspects of the universe — and very splendid it was too. But I'd like to recommend a shorter and perhaps more focussed series recently broadcast on BBC Four. This was Professor Jim Al-Khalili's two-parter Everything and Nothing.
Two-part documentary which deals with two of the deepest questions there are - what is everything, and what is nothing?

In two epic, surreal and mind-expanding films, Professor Jim Al-Khalili searches for an answer to these questions as he explores the true size and shape of the universe and delves into the amazing science behind apparent nothingness.

The first part, Everything, sees Professor Al-Khalili set out to discover what the universe might actually look like. The journey takes him from the distant past to the boundaries of the known universe. Along the way he charts the remarkable stories of the men and women who discovered the truth about the cosmos and investigates how our understanding of space has been shaped by both mathematics and astronomy.

The second part, Nothing, explores science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. Jim sets out to answer one very simple question - what is nothing? His journey ends with perhaps the most profound insight about reality that humanity has ever made. Everything came from nothing. The quantum world of the super-small shaped the vast universe we inhabit today, and Jim can prove it.
