27 days to power in May

This is a joint review of the books “22 days in May” by David Laws and “5 days to power” by Rob Wilson on the negotiations to form the Coalition government following the May 2010 General Election. The Laws book is his personal account of those negotiations, and his subsequent brief period in office. The Wilson book is drawn more widely, although he is a Conservative MP. The title of this blog post is a search engine unfriendly mashup of the two titles.

The Liberal Democrats started planning for negotiations in the event of a hung parliament towards the end 2009, this was done secretly by Danny Alexander, David Laws, Chris Huhne and Andrew Stunell on the direction of Nick Clegg. Their consensus, pre-election, was that depending on electoral arithmetic a coalition with Labour or a “confidence and supply” with Tories were the best outcomes for the hung parliament regime where no party had an overall majority. However, Chris Huhne argued that coalition with the Tories was better than “confidence and supply”. Confidence and supply means that the junior party supports the senior for votes of confidence, and for budgetary votes. Huhne argued that under these circumstances LibDems would get all of the blame for difficult government decisions which they supported, without any say over policy. The Tories set up a similar group approximately two weeks before the election comprising William Hague, Ed Llewellyn, George Osborne and Oliver Letwin. Labour apparently did no group planning, their negotiating team comprised Lord’s Mandelson and Adonis (a former LibDem), Ed Balls, Ed Miliband and Harriet Harman. The civil service also seems to have been very well prepared to support negotiations and had a strong preference for coalition over other forms of government. There are strong hints that the civil service were deeply concerned at the prospect of a minority government, or a “confidence and supply” agreement would be bad for confidence in the economy.

The 2010 general election gave the Tories 306 seats, Labour 258, Liberal Democrats 57 and other parties 28 seats (including 8 DUP, 6 SNP, 5 Sinn Fein). This would give a Lib-Lab pact a majority over the Conservatives of 8 seats but with 28 votes with smaller parties so not technically a majority. A Tory-LibDem coalition gives 363 seats, with a majority over Labour of 105. Such a pact can take a rebellion (i.e. MPs of the coalition voting against it) of 35, in theory a Lib-Lab coalition could take no rebellion. In practice the 5 Sinn Fein MPs would likely not vote and the SNP would be unlikely to vote with Tories, except if there was something in it for Scotland.

This electoral maths suggest to me that the only real choice was what form the agreement with the Tories should take: no agreement – likely leading to a new election, “confidence and supply” or full coalition. Coalition with Labour looked really hairy in terms of numbers of seats but there was a lot of enthusiasm in the Liberal Democrats and some enthusiasm in Labour for this. The generation of LibDem MPs who had entered the parliament opposing Tory governments (Paddy Ashdown, Vince Cable, Charles Kennedy, Don Foster etc) were particularly keen. Gordon Brown was keen to form a coalition, and from the Labour team Mandelson and Adonis. Clearly from a negotiating point of view the fact that a coalition with Labour was feasible was a strong card to play.

Steve Richards, in The Independent, prefers to characterise the Coalition agreement between LibDem and Tory as the result of a take over by Orange Book Liberal Democrats, against the will of the party. This seems to misunderstand the internal workings of the party: both the parliamentary party (Commons and Lords) and the federal executive were consulted at the time on how negotiations should progress. They also voted on the outcome, as did the wider membership at a special conference held shortly thereafter. Many of these would be people just like me who would have been nervous of coalition with Tories, and many would have initially preferred coalition with Labour. However, ultimately all of these groups voted emphatically for coalition with the Tories. One striking thing in the whole process was the amount of time the LibDems spent on internal consultation – Labour apparently did none of this, and in the Tory party it was cursory and ad hoc.

Lord Adonis has disputed David Laws assertion that the Labour team were disengaged and unhelpful in the negotiating process, and largely supported the Richards view of an Orange Book take over. Laws has responded to that accusation. Personally I’m happy to accept David Laws view of the Labour stance in negotiations: the external signs from Labour were that there was a substantial lack of will to form coalition in the parliamentary party (Blunkett, Reid, Burnham, Darling apparently all against), and that little or no preparation had been made to try to negotiate a coalition should the opportunity arise. Why was this? Was it an oversight? Did they feel formation of a coalition with the Liberal Democrats was so trivial as not to require any preparation? The accusation that the Labour negotiation team may have been split flies because it is so self-evidently plausible. My view is that the Labour party as a whole were tired of government, could not face coalition with a non-existent majority and could not face the prospect of implementing the cuts required (and promised by them too) to address the deficit. There’s no doubt that for some of them coalition with any other party, except with the most supine partner was anathema.
David Laws book is the one to read for LibDems or those wishing to understand LibDems better, the Wilson book is better for a more rounded view of the formation of the coalition. His tone with regard to his dear leader is somewhat grating but I’m sure others would say the same of the Laws book. A full account of the negotiations from the Labour perspective would be useful.
A vignette that I’ve not seen reported elsewhere: George Osborne offered David Laws a post in the shadow cabinet in 2004 and a cabinet post, were he to defect. Laws refused.

Book review: Trilobites! by Richard Fortey

Triarthus_lateral
Triarthrus eatoni from Beechers Trilobite bed

This week I’m reporting on “Trilobite! Eye witness to evolution” by Richard Fortey, which I came to via Attenborough’s “First Life” TV programme and advice from @crafthole. As usual this is intended as part notes for my own edification and part review. I read the Kindle version of this book, I’d recommend getting the paper version since the publishers have made no effort to incorporate any of the illustrations from the book into the electronic edition.

Fortey has a rather literary style which makes for rather pleasing reading: the book starts with a walk along the cliffs beyond Boscastle to a location used by Thomas Hardy in “A pair of blue eyes” where the hero comes face to face with a trilobite embedded in the cliffs. The book covers the discovery of trilobite anatomy; evolution, the drifting continents and what makes a palaeontologist tick.

Trilobites were common in the relatively early history of life on earth, during the Cambrian period, about 500 million years ago and became extinct at the end of the Permian period about 250 million years ago. The book starts with a description of trilobite anatomy – you can see the details on the wikipedia page. The basic fossil remnants are the hard shell of the trilobite, the upper surface shield – the closest living relatives to trilobites are things like woodlice and the horseshoe crab (which Fortey eats in Thailand!). Generally legs and soft parts do not fossilise, so it was some time before these structures were understood.

The first written record of a trilobite was by Dr Lhwyd in a letter to Martin Lister, reported to the Royal Society in 1699. It is a fleeting mention, and he mis-identifies his find as a “skeleton of some flat fish”, noting that they are abundant but his illustration is quite clearly of a trilobite. Dr Lhwyd writes from Wales and much of the early history of the trilobite’s discovery is tied up with Wales, trilobites are characteristic of the Cambrian period, named after Wales.

The image at the top of this post illustrates the discovery of trilobite legs. Most trilobites lost their legs in the fossilisation process, they are flimsy and poorly armoured. However in the case of the Beechers’ trilobite bed special preservation circumstances have fossilised the legs, in this case picked out in ‘fools gold’ or iron pyrite.

I was rather impressed by the chapter on trilobite eyes, as reported in my post on First Life, trilobite eyes are made from calcite – an array of calcite hexagonal prisms in the eye channels light to light receptors. Calcite is birefringent, one of the features of this property is that light only travels along the prisms to the light sensors if it enters them square on. So the relatively large number of calcite prisms in trilobite eyes suggest resolution comes from directional selectivity of the prisms. Some trilobite eyes are more complex than this: the Phacops eye is comprised of fewer prisms but with cunning lenses at the outside faces which work using magnesium concentration gradients to eliminate chromatic aberration – this suggests they channel light to multiple light receptors. Calcite is calcium carbonate, but the calcium can be selectively replaced by magnesium which changes it’s optical properties – in terms of man-made optics this type of thing is feasible but it’s pretty sophisticated. Reading this on the train the temptation to grab fellow commuters and jab my finger at the appropriate paragraph shouting “Have you read this about trilobite eyes, it is flippin’ incredible!!” was almost overwhelming!

Fortey is clearly passionate about his topic, as he says of breaking rocks to find the trilobites therein:

“Hardened criminals used to be required to do the same thing before it was banned as inhumane. I loved it.”

He works as a palaeontologists tasked with identifying trilobites, and if necessary creating new species. I learnt that the Linnean binomial system is slightly more complex than I thought, as well as having a two part name each species is tagged with the name of the person who first described a species this helps the expert in the field trace the original citation for a species. You gain the impression of someone able to identify one trilobite of a myriad potential species from mere fragments, in the manner of those archaeologists who can apparently build a pot, complete with its history, from a tiny shard. As arthropods with tough exoskeletons, trilobites moulted their shells to grow – each animal strewing the landscape with potential fossil fragments: fossil factories, Fortey calls them. He goes into some detail of the inferred life styles of trilobites and their development i.e how juveniles grow into adults. For some of the developmental stuff it would be nice to see the supporting fossils: it sounds ferociously difficult separating juvenile forms from different species of trilobite.

The large variety of trilobites, and their appearance in the early days of fossilising life, makes them a useful tool in the study of how evolution operates. Fortey rebuts the proposal by Stephen Jay Gould in “Wonderful Life” for a Cambrian explosion producing massive diversity of forms, beyond what we see now. Arguing from research by former colleagues that the variation in forms discovered in the Burgess Shale is much smaller than Gould claims. The difference being in the interpretation of how diverse forms are from relatively indistinct fossils. This is perhaps a warning to the casual reader that controversies are easily hidden in the popular science literature.

A second application of trilobites is in the dating of rocks: they are very common, fossilise well and, over a period of time, evolved into many distinctive forms which makes them ideal for the purpose. Finally they can also be used in the reconstruction of ancient continents: identifying common collections of trilobites in disparate parts of the world suggests they were originally found in one place.

As mentioned at the top of page, my Kindle edition of this book was bereft of illustrations but by the power of google, I can give you phacops, famous for it’s fancy eyes, ollenelus – one of the commonest of the early trilobites, calymene blumenbachii pleasingly convex as Fortey says, paradoxides another early species, Ogygiocarella debuchii as discovered by Dr Lhywd.

I found this book most useful as an insight into the mind of a palaeontologist and a taxonomist.

Kindle-ing

kindleAnother in an occasional series of gadget reviews, and more general thoughts on books. This time I look at the Amazon Kindle, my latest gadgety purchase – I have the WiFi only version with added leather carry case. The Kindle is an electronic device onto which books can be downloaded from a range of sources. In a sense the device is a side issue, Kindle software is available for smartphones (I have it on my HTC Desire), and computers. The main action for the Kindle is in the ecosystem: it makes it very easy to spend money on Amazon!

There are quite a few books available in the Kindle Store on Amazon, both free and paid. The paid offerings are a little cheaper than their paper equivalents but not hugely so. In addition PDF files can be read using the device, it will also play MP3 audio files. The Kindle Store also has links out to places where free content can be downloaded. For example, Project Gutenberg holds a wide variety of out of copyright material in a variety of e-book formats.

As long as you’re prepared to compromise a little you’ll not run short of things to read –  I’d like to read the Patrick O’Brian Aubrey-Maturin series but they are not yet available for download. Only three of the top ten Amazon bestsellers are available in Kindle format at the moment. So far I’ve bought “Trilobite!” by Richard Fortey and “22 days in May” by David Laws. I also have “Sustainable Energy – without the hot air” by David Mackay which I got as a free download, and converted to an appropriate format using Calibre e-book Management, this is available as a community conversion of the original HTML files. Books can be transferred to the Kindle by WiFi, or direct cable connection. Buying books is magically easy – press button, wait a minute and you’re done!

Compared to an HTC Desire the Kindle interface feels rather clunky, I kept wanting to change pages by touch! Having said this moving from page to page is ergonomically easy: there are a couple of handy page forward / page backward buttons suited to either handedness. Page changes feel ever so slightly ponderous with a bit of a flash as the page changes. The battery life is very good, the display is e-ink based and so static display takes no power, only switching pages requires power. The display size is about right and it is very nice to read from, when I first opened the device I assumed the picture on the screen was a piece of paper for display purposes. There are a range of options for adjusting text size, spacing and so forth, although I found some glitches with text size control.

The Kindle is ideal for plain text, however for text with diagrams it is a bit hit-and-miss, although the quality of the display is good enough to show quite detailed greyscale images in the case of the Fortey book these have simply not been included by the publisher. The Mackay book includes figures but the placement of the figures in the text has largely been done automatically and is a bit wobbly. I’d really like to try a book with illustrations which have been done properly – any recommendations then please comment.

The benefit of the Kindle with non-fiction is that searching, bookmarking, and highlighting are all relatively straightforward. I have religious objections against making marks in paper books – I think as a result of using the library as a child. It’s also possible to add notes to a book and to see the “favourite” notes of others.

The problem is the Kindle misses the display aspects of book owning and reading; my house is full of books collected over 20 years. They are my extended phenotype; they tell you something about me. If you visit my house you can see my books – you might want to borrow one. The Kindle cuts this away, you can’t see what is on my Kindle, and if even if you could, you couldn’t borrow it. I’ve tried to replicate the bookshelf aspect in my Shelfari account, where you can see what I am reading and what I have read. I’m also missing the pile of books beside my bed. I’m an old-fashioned animal that misses physical objects.

Overall: not at all bad, reading raw text is comfortable, the whole buying new text is frighteningly easy, and a range of formats can be read. I’m looking forward to using the Kindle to avoid my mortal holiday fear – that I might run out of things to read!

Book review: The Scientific Revolution and the Origins of Modern Science by John Henry

ScientificRevolution_JohnHenryThe book I review in this post is “The Scientific Revolution and the Origins of Modern Science” by John Henry. In contrast to previous history books I have read this is neither popular history of science, nor original material but instead an academic text book. My first impressions are that it is a slim volume (100 pages) and contains no pictures! Since childhood I have tended towards the weightier volume, feeling it better value for money.

The Scientific Revolution is a period in European history during which the way in which science was done changed dramatically. The main action took place during the 17th century with lesser changes occurring in the 15th and 18th centuries. The Royal Society, on which I have blogged several times, plays a part in this Revolution and God’s Philosophers by James Hannam is one view of the preamble to the period.

The book starts with a brief introduction to historiography (methods of history research) of the Scientific Revolution, with a particular warning against “whiggish” behaviour: that’s to say looking back into the past and extracting from it that thread that leads to the future, ignoring all other things – the preferred alternative being to look at a period as a whole in its own terms. History as introduced by scientists is often highly whiggish.

Next up is a highlighting of the Renaissance, a period immediately prior to the Scientific Revolution wherein much renewed effort was made to learn from the Classics, the importance of the Renaissance appears to have been in initiating a break from the natural philosophy and theology taught in the universities of the time, which were teaching rather than research institutions.

The Scientific Revolution introduced two “methods of science” which differentiated it from the previous studies of natural philosophy: mathematisation and experiment. Mathematisation in that for sciences particularly relating to physics the aim became to develop a mathematical model for the physical behaviour observed. Prior to the Revolution mathematics was seen almost as a menial craft, inferior to both natural philosophy and theology which relied on logical chains of deduction to establish causes. These days mathematics has a far higher prestige, as illustrated in this xkcd comicstrip. The second element of experimentation means the use of controlled experimentation rather than pure thought to determine true facts.

One of the more surprising insights for me was the influence of magic on the developing science, very much in parallel to the influence of alchemy on the developing chemical sciences: magic was a physical equivalent. Magicians were intensely interested in the mysterious properties of physical objects and were early users of lenses and mirrors. The experience they developed in manipulating physical objects was the equivalent of the experience the alchemists gained in manipulating chemicals. Some of this thinking went forward into the new science the remaining rump of bonkers stuff left behind.

It’s very easy to glibly teach of forces and atoms to students, or perhaps blithely demonstrate the solution to an, on the face of it, tricky integral. However, we take a lot for granted: the great names of the past were at least as intelligent as more recent ones such as Einstein or Maxwell yet they struggled greatly with the idea of a force acting at a distance and so forth and that’s because these ideas are actually not obvious except in retrospect. Mechanical philosophies of Descartes and Hobbes were amongst the competing ideas for a “system of the world” ultimately supplanted by Newton.

Henry highlights that most of the participants in the Scientific Revolution were religiously devout, as were many in that time. An interesting idea taken up, but now apparently rejected, was that Puritanism was essential in driving the Scientific Revolution in Britain. Despite this, it was in this period that atheism started to appear.

A few times Henry refers to differences in emphasis between the developing new science in Britain when compared to the Continent. In Britain the emphasis was on an almost legalistic approach with purportedly bare facts presented to a jury in the form, for example, of the fellows of the Royal Society – theorising was in principle depreciated. This approach originates with Francis Bacon, a former Attorney General and experienced legal figure. On the Continent the emphasis was different, experiments were seen more as a demonstration of the correctness of a theory. The reason for this difference is laid at the door of the English Civil War, only briefly passed when the Royal Society was founded. It is argued that this largely non-confrontational style arose from a need for a bit of peace following the recent turmoil.

In sum I found this book an interesting experience: it’s very dense and heavily referenced. Popular history of science tends to revolve around individual biography and it’s nice to get some context for these lives. I’m particularly interested in following up some of the references to other European learned societies.

Book review: God’s Philosophers by James Hannam

God_the_Geometer I seem to be on a run of book reviewing at the moment, as I’ve indicated before these are as much for me as they are for you! This weeks contribution is on “God’s Philosophers: How the Medieval World laid the foundations of Modern Science“ by James Hannam. This book looks at the development of science, or at least a precursor to modern science, during the Middle Ages (5th-15th century). This fits in with my previous book reviewing which has gone back to the founding of the Royal Society (1662), and a little earlier with Gerard Mercator (1512-1594).

To my mind the book makes a poor start in the introduction by telling me how everything I believe about the Middle (or Dark) Ages is wrong, and so is everyone else. I’m prepared to accept that my visualisation of the Dark Ages, as being quite literally Dark with peasants fumbling around in a permanent twilight may be wrong, however this type of introduction generally leaves me believing that the writer is a conspiracy theorist!

A recurring theme of the book is how those studying natural philosophy (a convenient term for the proto-science) continually ran the risk of being accused of heresy. Hannam seems to portray the treatment of heresy as not really so bad: only 1 in 20 trials resulted in burning at the stake, there wasn’t much torture, the victim was asking for it, the church handed over the heretics to the secular authorities who carried out the most terrible punishment. This seems to treat lightly the death, by burning at the stake, of people who simply believed something different. Perhaps more insidiously anyone studying natural philosophy had to have an eye to what the church believed in case what they studied was considered to be heretical. Later Hannam’s defence turns out to be more narrowly defined: he sees himself as defending the Catholic Church against Protestants. He reserves a special ire for humanists, those in the Renaissance who had a particular fondness for studying the ancient classics.

This said, the book is a nice overview of the development of the academic life after the fall of the Roman Empire, with the early universities in Italy and France growing up as offshoots from the great cathedrals. The very earliest of these institutions taught law, and sometime later medicine although the core of early teaching was in theology. A great deal of effort was expended in recovering the work of the Ancients (Greek philosophers) this was made difficult by the absence of much knowledge of Greek in Western Europe. The Arabs had picked up much of this material in an earlier period but translated it into Arabic rather than Greek whilst Western Europe had Latin as a common scholarly language. Interest was primarily in Aristotle, although later the works of Plato were re-discovered. In some ways it’s this aspect of the Middle Age and Renaissance enterprise which is so confusing to a modern scientist. It just looks like it would be far easier, and quicker, to make a fresh start and discover things for yourself rather than dredge through ancient, partial manuscripts in ill-known languages for clues.

There are various places in the book where I can feel myself trying to shout back through the ages “Yes, yes, you’re on the right track, keep going!”. Only to see the protagonist draw back at the last minute or for their work to be subsequently ignored. Examples include Nicole Oresme (1323-1382) and his use of graphs in understanding physical ideas. Or the theory of impetus developed by Jean Buridan (~1300-1358), which is a very direct precursor of modern theories of mechanical motion. Similarly isolated sparks spoke of doing controlled experiments to test theories, and the idea that mathematics could be used to describe physical processes. However these ideas did not seem to start drawing together until the period in which Galileo lived (1564-1642).

The part that astrology played in the development of astronomy is rather illuminating, as part of their programme the astrologers wanted to known exactly where heavenly bodies would be at some point in time in the past or future therefore they expended considerable, skilled effort in measuring the locations of these bodies and building models from these measurements. This was the work that lead Copernicus to propose a heliocentric solar system, and would have fed into Newton’s work on gravity, and all done for completely ridiculous reasons. This also highlights some of the oddities in the thinking of the early pioneers of the modern period, for example William Gilbert, who did excellent work on magnetism did it in a distinctly odd framework – he believed the magnet was the soul of a planet, similarly William Harvey’s work on the circulation of blood and Isaac Newton’s obsessive alchemy and bible study.

During the Middle Ages there were various technological developments: the mechanical clock (Norwich, 1273), spectacles (Venice, 1300), modern printing (by Gutenberg around 1439). Paper making had been brought to Europe at some time before 1276 when the first paper mill is recorded in central Italy. Gunpowder was first mentioned in Europe by Roger Bacon (1267), having been invented in China in around the 9th century. These inventions largely arose outside of the university system.

The book ends with the death of Galileo in 1642, who had been subjected to a trial for heresy following which he was held under house arrest for the remainder of his life. The book makes clear, that in common with Newton, Galileo was “standing on the shoulders of giants” drawing heavily on work in the Middle Ages – although synthesising into a coherent whole, making his own additions and also covering a large range of topics over his lifetime.

Finally there is a timeline, a cast of characters and a nice, manageable set of further readings.

I feel ambivalent about this book, the historical aspects of it I found very interesting, the proselytising less so. It seems evident that there was progress in proto-science during the Middle Ages, and also in technology. Hannam claims that the Catholic Church facilitated this progress; the evidence he presents is mixed – they supported scholarship and the founding of universities but simultaneously ran a system of Inquisition to detect heresy which made free academic enquiry difficult.
