peak sun

We don’t have all the data for August yet, and today is quite sunny, but it’s not going to change these figures much.

These two plots show our daily solar power generation in kWh, month by month.  The first plot shows the actual daily values (with some jitter applied to the horizontal position, to prevent points overlapping).  The second shows violin plots (box and whisker plots of median and quartile statistics, overlaying a kernel density plot, which is a smoothed version of the jitter plot).




So it looks like summer is over!

Notice that August has a low outlier, for a very dark and cloudy day.  That was Bank Holiday Monday, of course!  Other months have had days as bad as this, but they weren’t outliers; other days in that month were poor too, and the overall interquartile range is high.  August days are relatively clustered around mediocre (so a small interquartile range), making the Bank Holiday a significantly bad day!

book review: Losing the Head of Philip K Dick

David Dufty.
Losing the Head of Philip K Dick.
(aka Lost in Transit, aka How to Build an Android)
Oneworld. 2011

In 2005, a disparate group of computer AI and robotics researchers got together, and decided to build an android recreation of the science fiction writer Philip K. Dick. They chose Dick because they had access to a huge archive of his writings and in-depth interviews, allowing them to build an Eliza-esque system that could converse in a Dick-like manner by drawing on this large database. The project went well, drawing in fascinated crowds, until the fateful day they lost the android’s head…

This is another of those “true-life fly-on-the-wall” tales of heroic scientific and engineering endeavour. It is an interesting, if somewhat pedestrian, recounting of a true story that could never be told as fiction, as it is too unlikely. Here the author is himself a researcher, rather than a journalist, so we get fewer of those irritating vignettes common to works that focus mainly on the people.

Yet there is a disappointing lack of technical detail. For example, we get a few transcripts of amazing conversations the android held with the public (although presumably heavily editied: there is a YouTube video of an actual “conversation” that is impressive, but less “intelligent”; there is also a website with some photos), but we get only a glimpse of what is going on inside the android’s “head” (the relevant computers are actually in a box to one side) at the time.

One interesting piece of technical discussion is about the so-called “uncanny valley” of near-lifelike, and hence creepy, robots. David Hanson, the developer of the life-like animated head, disliked the notion, so delved into the literature to find the evidence. Apparently, there was none: it was originally just an hypothesis, that then got taken up. Moral: always go back to the source material!

Moral 2: always make sure you have all your belongings with you when leaving the plane. The most I’ve left behind is a book. A head is a whole other problem.

Loncon 3 : Monday

For the sake of tradition, here is a photo from our hotel window, showing the ExCeL loading bays at the back, and the work on the new Crossrail in the front.

A Room With A View
After breakfast, we checked out of the hotel, leaving our luggage for later collection, and walked across to the ExCeL for the last day of the Worldcon.

First up was a talk by Dr Nicholas Jackson, on Knots in Non-Euclidean Space.  Nicholas has been giving interesting general talks on mathematics at Eastercons: this time it was based on some of his own work.  I got lost towards the end, but it was all done in his clear, amusing, and interesting style.

Next was a panel on The Politics of the Culture.  Banks was a fairly consistent Old Labour social democrat; reviewers seem to assume his characters’ opinions are his own, though.  Ken MacLeod told the story of The Use of Calculators as Iain’s proposed route to his Marxist communist utopia of “a stateless and classless society based on automation and abundance”. Many of the Culture novels are based on the Minds having a strong sense of the cost of backwardness, and a moral imperative to uplift, and then working through the complications and consequences with a degree of rigour.

At noon I went to see The Compleat Wrks of Wllm Shkspr (Abridged), by the RSC Shakespeare Company: 37 plays in 97 minutes, including all the comedies at once, and Hamlet several times, faster and faster, and then backwards.  I’d seen it many years ago; it was well worth seeing again.

Lunch, and then my final panel the con: The Scientific Culture.  Here no Banksian reference, just a discussion of the culture (with a small ‘c’) of science and scientists.

The end of a great Worldcon, my fourth: I went to Glasgow 2005, Glasgow 1995, and Brighton 1987.

And, coming full circle, I left the ExCel for Brighton, where tomorrow I give a tutorial on complexity and emergence at the Student Conference on Complexity Science.

And so to bed, in a different hotel, now by the seaside.

Loncon 3 : Sunday

Sunday started out well with Dr Jenny Rohn’s great talk on antibiotic resistance in Revenge of the bugs: how bacteria have re-emerged as a serious threat to our existence.  Bacteria have been shaping our evolution by slaughtering the weak for as long as we can tell.  In the 20th century we began to fight back with antibiotics, but the bugs are out-evolving them, at an accelerating rate.  Not only that, but we’ve stopped making new antibiotics, because it’s just not financially viable: the low hanging fruit is gone, and the financial incentives are wrong.  It’s a health catastrophe on a par with climate change.  What to do?  Write to your MP demanding action!  And don’t take antibiotics for a cold.

Next was Authors Accept, Encourage, and Create Fan Works Too, a panel about fanfic.  All the panel indulged to some degree; some had learned their craft that way.  Despite some people looking down on fanfic, they pointed out that screenwriters, for example, are all playing in someone else’s sandbox.  If you do work for hire, there are restrictions: don’t kill off a major character, no explicit sex, no crossovers; so for a fan writer, why would you bother? Some authors send cease and desist letters under the mistaken impression they need to do so to protect their copyright (they don’t) or their trademark (they could authorise instead).

Next was a history panel, Seeing the Future, Knowing the Past.  Real history is messy, full of contingency, short bloodlines, and instability, so why does fantasy insist on prophesy and “rightful heirs”?  And all this “last in the long line of kings”, like Aragorn.  In reality, you are either everyone’s ancestor, or no-one’s; nearly everyone is a descendant of Genghis Khan, and he died only about 800 years ago.  However, it is a function of fiction to put order onto messiness and chaos; it provides a controlled environment where we can get answers (although this is a relatively recent trend in literature).  Also, fantasy likes grand overarching narratives.  In reality, prophesies do exist, but are often written in retrospect.  People blame Tolkien, but he didn’t do this kind of thing: he was a “messy” writer, with lots happening. Quote of the panel: “I don’t blame Tolkien; I blame Terry Brooks!”

The Secrecy in Science panel discussed to pros and cons of keeping experimental data secret until it has been fully analysed, and published by the scientists who have spent most of their career on the specific project.  NASA releases all its data immediately; ESA is more restrictive. There was also some discussion on the move to publishing the results of all drug trials, not just the successful ones, and the use of Open Access.

Lablit (laboratory literature) discussed a wide range of stories featuring scientists going about their research, as part of a contemporary story, not science fiction.

Botanical Conquistadors was an interesting panel.  The moderator asked the rest of the panel a sequence of questions designed to get them to incrementally design a terraforming strategy.  The structure worked really well, leading to musings on giant evolved tardigrades, planet-covering HeLa cells, and Japanese knotweed as a mulch.  We also learnt interesting facts about terraforming, such as the need for nitrogen, and how mosquitoes are a key species as food for birds.

We finished off the day attending the Hugo Ceremony.

And so to bed.

Loncon 3 : Saturday

At breakfast today, we shared a table with a woman with limited mobility, who had hired a mobility scooter to traverse the ExCeL.  She amused us with descriptions of many different ways to incorporate such the scooter in a hall costume, Davros being merely the starting point.

My first panel was 1938: The Year In SF/F, discussing the retro-Hugos.  The world was different then: SF was mainly published in magazines in the US, and it was possible to read everything every month, twice!  The UK market was completely separate.  It was suggested that some of the retro awards were won because present day fans were voting for the author, not the work; one panelists suggested there should be a rediscovery award for unfairly neglected writes, and suggested Raymond Z Gallun as a nominee.  It was also noted that every book on the 1938 list was part of a series.

Next came Banksian, a  panel discussing what the term means, and who is writing it today. Ultraviolence as a feature was discussed, but it was pointed out that while Banks wrote violence, it was never the star; there was always a strong moral content, and the reader was supposed to be sickened by the violence.  Next on the list was the expansive, inventive scope and scale, of time, of events, of artefacts.  Before Banks, spaceships were 500 yards long, after, they were 500 miles.  Then the panel discussed his experimental, unusual writing techniques: the inverted story structure in Use of Weapons; the dialect in Feesum Endjinn; 2nd person narrative; epistolary structure of Excession.  Of course, anyone copying any of these styles wouldn’t be experimental!  Banksian politics is socialist utopian individualism, which needs the Minds to keep everything stable.

With a change of focus from science fiction to science, I next went to the Climate Change Narratives panel.  The discussion oscillated between how to write a compelling story about climate change, and how to redesign economics to properly account for climate change.

Next off to a fantasy panel:  “Your ‘realistic’ fantasy is a washed out colourless emptiness compared to the Rabelaisian reality.” Discuss.  Some authors claim to write their medieval fantasies full of straight white men, because “that’s how it was back then”.  The panel of historians begged to differ (although Edward James pointed out that Rabelais wrote fantasy, not reality).  Despite this, Kari had a lovely rant about how one of the problems of being a Celticist is the Celtic fantasy novels like Marion Zimmer Bradley’s Mists of Avalon and Gael Baudino’s Gossamer Axe, promulgating the Californian neo-pagan Myth of the Celtic Woman: quote of the panel: “Celtic women were property, not radical lesbian separatists!”

I grabbed a mid-afternoon pasty before going along to the Science Fiction Encyclopedia Reunion, where we heard the fascinating story of the design and production of the Science Fiction Encyclopedia, from the first edition onwards.

Next was The Post Human Future, a talk delivered by Astronomer Royal Martin Rees.  The first part was based around his book Our Final Century (he said how the publisher cut his question mark, and the US title was Our Final Hour, maybe because they want instant gratification!), which is about all the things that could wipe us out.  He then talked about space flight, and how it would be better to commercialise it as a dangerous sport rather than as tourism, so that the inevitable accidents won’t be as traumatic.  He finished off talking about the period from when the Andormeda Galaxy crashes into ours in 4bn years, to the far future of the universe, and the multiverse.  His talk was peppered with wry jokes and science fiction references.  Quote of the talk: “I tell my students it’s better to read first rate science fiction rather than second rate science: it’s more stimulating, and no more likely to be wrong”.

We finished off the evening with the Masquerade, which demonstrated amazing creativity and attention to detail.

And so to bed.

Loncon 3 : Friday

Day 2 of the Worldcon started with breakfast in the hotel.  We were late enough down to have to move into the overflow space.  We were joined first by someone who worked in the hotel, curious about the convention.  Next we were joined by a couple from Canada.  In fact, they were from St John’s, Newfoundland, where I had spent 10 days only a couple of weeks earlier! One of them worked at Memorial University, and knew the person I was visiting there.  It just confirms my theory that there are only 400 people in the world, 200 who you know, and 200 who act as backdrop.

First off was a talk by Prof Ian Stewart on The Science of Discworld, partly about the content of the four books he wrote with Jack Cohen and Terry Pratchett, and partly about the history of their production.  The aim is to explain science, which isn’t a problem.  The problem is that the Discworld short story that  forms part of each book must make sense in its own right, yet have no impact on the overall Discworld canon.  He told the story of reading a biography of Darwin, with all the accidents that nearly stopped his voyage of discovery, and the coincidences that then put him back on track.  Ian explained to his co-authors: “It’s the Wizards at work!”  Jack asked him what he was on.  [But, as my breakfast conversation shows, coincidences like this happen all the time.]

Next was the panel on The Pleasures of a Good, Long Info-Dump.  Science fiction often uses the info-dump, or the “As you  know, Bob…” scene, to provide essential background information.  In mainstream literature, this is thought to be A Bad Thing.  Here Kim Stanley Robinson had a long, interesting rant on why he rejected the term “info-dump”, a pejorative term invented by the Turkey City Lexicon, and called it “a failed attempt to assert you know how fiction works”.  Older fiction, like Les Miserables or Moby Dick, revel in the “expository lump”, and so modernism invented rules as a reaction to that, requiring “show, don’t tell”.  But science fiction is different.  It should not feel it has to conform to these other rules, which can be turned into an ideological control, suppressing SF’s way of being subversive, by reducing its power to blow people’s minds.  Alternatives to a lecture include using snippets from fictional encyclopedias (we were told Matt Ruff’s Mirage takes this to another level, by including the edit wars in an on-line encyclopedia), or use of what Jo Walton calls incluing.  Quote of the panel (from Cory Doctorow, of course): “The best dumps come at the end of a lot of anticipation”.

Next I took a break, and went to the enormous hanger-like room housing the Art Show, the Dealers’ Room, and several related exhibitions.  Having them all in one place like this was great.

welcome from the Hawaiʻian Dalek (yes, the brown lumps are coconuts!)

At 1:30pm I went to Dr Tori Herridge’s talk on How to Make a Dwarf Mammoth.  Starting from fossil hunter Dorothea Bate’s 1904 adventure on Crete, we had a whirlwind and fascinating tour of the paleontology of mini mammoths in the Mediterranean, including how they have evolved and gone extinct multiple times, and in parallel on different islands.  I can now safely say I know at least an order of magnitude more about elephants than I did before.  The answer to the title: get  a mammoth (or two), get an island, and wait 50 thousand years.

The Interview with John Clute was very Clutean.  He talked about his early days, his first novel, being a critic, his use of Fantastika as a term for “the literature of the fantastic as a whole”, how Fantastika is essentially to be read literally not metaphorically, his novel Appleseed (written from a synopsis for a tie-in novel for Elite), and the Encyclopedia [of which more later].  Quote of the interview “To accept that to reveal a book is to spoil it privileges the reader’s first reading”.

In the Ian Stewart Interview, Nicholas Jackson interviewed Ian Stewart about his life in mathematics, his popular mathematical writings, his undergraduate rock band, and his work with Jack Cohen.  After Ian’s earlier descriptions of the coincidences in Darwin’s life, it was interesting to hear his own stories of how he got his university place at Cambridge without applying for it, and his first academic job at Warwick without applying for it.  Quote of the interview: “Agents alternate between saying ‘don’t write so many books!’ and ‘when’s the next book?’”

My final panel of the day was What's New in Maths, which included some discussion of the recent Fields Medal winners.  Quote of the panel, of the Clay Mathematics Institute Millennium Prize Problems: “There are easier ways to earn a million dollars”.

We rounded off the evening by going to the Worldcon Philharmonic Orchestra concert.

And so to bed.
