While in Dublin I went to see Broom Bridge, where William Rowan Hamilton was when he had the inspiration for quaternions, and scratched the equation on the bridge:



Not many people are likely to have made the trip because it's not in the middle of town the way you might think from hearing the story; but it was no detour for me because it's near where my aunt and uncle's house is.



When I got back and told everyone where I'd been my uncle said that was where he and my dad used to skip Mass and go fishing!

The Worldcon itself was sadly the most disappointing I've ever been to, so I quit two days early to have more time with the family and to drive down to Waterford and Cork.

Blimey, this setting everyone up with all the right settings in DW is murder on the mouse wrist. If anyone drops in or out of sight on either site, please bear with the management during this period.

John WINOLJ Holden just called to say he's coming round tomorrow lunchtime, so if anyone else wants to come and hang out, I'm in to visitors. This isn't a mooch for helpers; if you want to come round later in the afternoon when we're getting in the pizzas, you're very welcome to a slice and some beer. Speaking of which, I understand there's a beer festival in Reading this weekend.

It's also my birthday on Monday :-)

Now the Hugos have been awarded at Denvention, it's time for the annual moaning about the ageing of science fiction. Using [livejournal.com profile] nhw's data, I graphed the birth dates of Hugo and Nebula winners before, and I've graphed the median ages here:
more graphs, small but lots of them )
Again, I'm not seeing much to suggest the end is nigh. Median ages have risen before, and fallen before. I think the shocking statistic that only two awards have gone to writers born after 1970 (Tim Pratt and Elizabeth Bear who won the last two years' short story Hugos) is mainly a coincidence of threshold number: the upward trend in ages has happened to parallel the line of constant age, reflecting a delay in the appearance of the 1970s birth group for a few years longer than expected.

To me the big event is the collapse in the number of older writers represented at the novel length in the 80s, when the age range of Hugo and Nebula winners narrowed dramatically. The median ages have been climbing again from that low, as those young 80s writers grow older while continuing to win awards, and the younger writers are not coming in at a rate of exactly one year per year. That can change quickly: as the financial salesmen say "the market may go down as well as up".

I read this BBC news article saying "The average UK person will this year have a greater income than their US counterpart for the first time since the 19th Century, figures suggest." Now this may be true, but I would point out that "GDP divided by population" is not the same as "The income of the average person". The first is the mean, the second is the median.

What I mean is )

That's why I'm never interested in hearing whether something is "helping" or "hurting" the country's Gross Domestic Product. The income of average people depends much more on the shape of the distribution than its total size.

Update: Elsewhere in the BBC, someone gets it right.... )

With the ESA satellite COROT nearing its first 300 days in orbit, I hear that a truckload of new extrasolar planets are due to be announced to the world soon. These detections will be based on planetary transits, which means this may be the last time my graph of exoplanets detected by doppler spectroscopy (based on data from exoplanet.eu) represent a majority of all the exoplanets known, so I'd better pimp it one last time :-)

[livejournal.com profile] nhw posted that writers born between 1942 and 1951 are overrepresented in Hugo and Nebula awards, sparking a flurry of responses attempting to explain the decline of science fiction. I think the debate is mainly missing the fact that the Hugos and Nebulas have only been around for about fifty years, and the full range of a ten year cohort's output—from the first wunderkind born at the start of the ten years who wins an award at twenty five, to the grand old man born at the end who wins at seventy five—can easily span sixty years. Jack Williamson, of the 1902-11 cohort, won the Hugo and Nebula Best Novella awards in 2001 for "The Ultimate Earth" at the age of 93. Peter Beagle of the 1932-41 cohort won the best Novelette Hugo this year for "Two Hearts".

The Hugos didn't start to be awarded until 1953, and only 23 of them had been awarded (counting ties and collaborations) by 1964, the year before the Nebulas began. We can increase this to 35 by including twelve retro-Hugos. 334 Hugos and Nebulas have been awarded since 1965. The 1942-51 cohort are in that sweet spot where the Hugos and Nebulas in all four length categories (Short, Novelette, Novella, Novel) were available to be won at all stages in their careers, starting from 1965: the first award won by a member of the cohort was the 1965 Nebula for Best Novel, Babel-17 by Samuel R. Delany. The most recent is Connie Willis's Hugo for Best Novella, for "Inside Job".

"Younger" writers, i.e., those born after 1951, haven't had time to rack up the full number of awards possible for their cohort. If we had the Hugo and Nebula results from 2007-2047 available to us, the statistics might look a little different.

Edited to correct the "first Hugos in 1946" error. Thanks to [livejournal.com profile] timill

"...I do not think it means what you think it means."

The Guardian reports:

British officers took part in a US war game aimed at preparing for a possible invasion of Iran, despite repeated claims by the foreign secretary, Jack Straw, that a military strike against Iran is inconceivable.

"I've hired you to help me start a war. That's a prestigious line of work with a long and glorious tradition."

"You never said anything about killing anyone."

A Foreign Office spokesman said: "The foreign secretary has made his position very clear that military action is inconceivable. The Foreign Office regards speculation about war, particularly involving Britain, as unhelpful at a time when the diplomatic route is still being pursued."

After the con - Tuesday 18th Feb )

Wednesday 19th Feb )

Summary
The Sheraton was a great venue, right in the middle of Boston with great restaurants nearby. I kept hinting that I’d like to go eat at one of the Legal Sea Foods chain of restaurants, but all the Bostonians I was with declared it had gone downhill since the good old days, so I never got to try it for myself. One day when I’m back in Boston with some other new-in-town folks, perhaps. I’m strongly tempted to go back for Noreascon 4 next year, when the Worldcon takes the Sheraton, the Marriott, and the Hynes Convention Centre, with the very handy mall outside for fast food.

I had a fantastic time, great food, old friendships renewed and new friendships made. I enjoyed Boston as a city, and Boston fans were very friendly, although there seem to be so many of them that they don’t all know each other!

I’d especially like to thank Ellen Brody and Susan Murosako for encouraging me to come, and help finding accommodation, and acting as native guides in Boston; Mike Devney for offering emergency crash space; Victor and Sheila for their hospitality, and Gary Feldbaum for the room share. My extra special thanks to Ellen for driving me around Boston and showing me the city, even when I wasn't as gracious a guest as such a gracious host deserves.

Thanks to everyone else whose friendliness and generosity I’ve forgotten to mention, and I hope to see some of you again at Torcon.

Monday morning I went down to the bar where some of the fans snowed in by the blizzard had gathered. About 50 were still in the hotel, having missed flights or similar. Since my own flight was scheduled for Wednesday anyway, this was gravy for me. An extra con! Two for the price of one. They were calling it Snokone. Chatted with Hope Leibowitz, Michael Pins, Elaine Brennan, Sharon Sbarsky, Dave Cantor, met Naomi Fisher and Pat Molloy. George R. R. Martin was there too.Read more... )

Sunday morning I walked the long way from Victor and Sheila's place to the MBTA station in Central Square. I had intended to walk to Harvard Square, I don't know how I got turned around. Back at 11, dropped bags in Charlie and Feórag's room.

12:00 noon What Should Good Fantasy Do? Ellen Asher, Ellen Kushner, George R. R. Martin, Beth Meacham.
Charlie asked the question from the audience, "what should fantasy not do?". Ellen Kushner said at the end "let's take it to the bar", which doesn't make sense in an American con context; is this a borrowed expression from British fandom?Read more... )

No hotel breakfast for the room crasher, so I went out to the food court in the Prudential Mall for something, then back for the morning programme.

11:00am: Uplifting Biology Judith Berman, Tom Easton, Jeff Hecht, Shariann Lewitt, Robert J. Sawyer. The discussion was more around psychology than physical features as I’d expected. Shariann Lewitt had to physically move the microphone away from RobWho? )

Victor Gonzalez and Sheila Lightsey kindly invited me back to Cambridge to stay on their sofa, so we went back across the Charles River by taxi, where I met their cats Cassie, Art and Trouble.
