I was a teenage rower, and now am a middle aged rower, so most of my exercise comes on the river, or on an erg (disregarding the 11 miles a day cycle to work, which is definitely good for me too, but that counts as base load). So today I did 10 km, which took me a fraction less than 40 mins, and the end of it I was sufficiently tired to do nothing but pant for 5 mins, and then my arms shook while eating lunch. But a few hours later I am fully recovered, I think.
The contrast I’m trying to draw is with running, which I’m getting into a little bit. When I run 5 km, I end up not truely tired, but more feeling damaged: my thighs ache, my calves ache, but I’m still quite capable of moving. Perhaps I just haven’t learnt how to try hard enough while running. My time for 5km, incidentally, is a little under 25 mins, so 5 mins/km, which is worse than my 10 km rowing speed. But I’m not sure how the two compare.
I do wonder if I should hive off all the non-science junk onto a non-science blog. But no-one is complaining so far.
I’m sure the risible rubbish in Denial Depot would once upon a time have raised some outrage, or at least the feeling that it might need rebutting. But now it just seems boring (and I’m only writing this as a placeholder for a change in interests). Eli briefly snarks it, and Coby apparently intends to read it. Perhaps Schellnhuber is right.
[Various commenters assure me that it is a spoof. I certainly hope so. But this just proves my own personal point: I really don’t care enough to find out! -W]
Stretham Old Engine is a former pumping engine out in the fens; visiting it is not too dissimilar to the Museum of fenland drainage that James visited a while back. You can see it from above and you can visit it’s own website: strethamoldengine.org.uk/.
It is best to visit it by boat, though, which we managed on a wednesday during the school holidays, and were even lucky enough to find it open. Sadly it is trapped in something of a vicious circle: they don’t open often so get few visitors; and since they get few visitors they can’t afford to open very often.
Pix here; and I’ll in-line a few.
Anyone who was anyone (and some who aren’t 🙂 went to the great Cam clean up. Unlike James, I didn’t bother turn up for the speeches. This may have been a mistake, as not only did I not get on the grapple teams but also by the time I’d come along most of the litter had gone too. I walked from the FSG (G not J to keep Andy happy!) to the railway bridge and found somewhat less than a bin liner’s worth. Still, it was a lovely day for it, I got to abuse Meg in the tub (sorry) and I saw some nice lichen:
Weird sight of the day was the diver finding stuff under the Elizabeth Way bridge, as marked by his inflatable floaty-thing, which lead to log-jams of VIII’s as they tried to avoid mowing him down. Which they couldn’t even if they tried, since an VIII draws about a foot of water at the most, and he was well down.
There were the traditional lorry-loads of bikes dredged out and kids watching the show. A fair morning out, though not as much fun as going rowing.
After dinner, a 5km run:
A while ago, crowing over the extent of Arctic sea ice this winter and the possibility this would mean loadsa ice this summer, I noted that “it is clear from that, that the winter anomaly doesn’t correlate too closely with the summer minimum”. That was based on the IJIS plot, and on little more than that the 2008 winter ice is clearly on the high side while the summer ice was on the low side. C challenged my assertion, and drew some plots, and decided in the end that maybe I was right. He was also kind enough to send me his spread sheet, but I didn’t get along with it, so have faked up my own google spreadsheet: here if you’re interested.
And the pic below, if all the googly magic works out, is a plot of the winter (March) anomaly and the summer (September) anomaly. We see what we already know: ice is declining, and 2007/8 are anomalously low. If you scatter plot the anomalies, then there is a strong relationship, because of the linear trend.
So it is more interesting to know if one year’s winter anomaly is followed by a summer anomaly. Below is a scatter plot of the winter (March) anomaly-from-linear-trend against the summer (September) anomaly-f-l-t (making the possibly unwarranted assumption that I’ve got my excel script right).
I think it is a blob. There is little sign of a relation.
All this seems vaguely interesting, and you would have thought someone must have published on it. Anyone got a ref?
Ice data from ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/Sep/N_09_area.txt and related.
Finally, I’ve been promoted to Rouge admin status. It is a game a little like Mornington Crescent: there are no rules, but it would be a dreadful faux pas to break them.
The excuse was quite a suitable one: I blocked a septic who in a huff had said “I’d quite like to be blocked” but who then proved about as consistent as most septics by demanding to be unblocked.
If you’re interested in more heavy-handed wiki humour, WP:GIANTDICK is good (or this version).
I would have thought that saying the Israeli state was racist was just the bleedin’ obvious; but apparently it is controversial. Odd. Maybe the “totally” was OTT. I suppose having the Iranians saying it must be irritating. So what was the conference for? To discuss racism without at any point admitting that anyone is?
