Today was the anniversary of my glorious 1:36 in the Cambridge Half Marathon. Today, alas, I only managed 1:41 so at that rate Jules will be steaming past me before many more years have passed. I remain fairly confident of out-erging her over the distance though. Here I am with other folk from our rowing club that were running. You’ll notice that most of them are female. Maggie in the background, if you were wondering. Onwards, to Brighton.
But other things are happening. You’ll have to wait just a little longer for my deeply valuable thoughts on the Ukraine crisis; this post is Misc.
Last night I spent quite a while broswing wiki and reminding myself about the different sorts of supernova and their causes. There’s a wonderful majesty and scope to the whole thing. CIP has a nice post on GHGs to the stars, on some speculations about first-generations stars having little “metals” and hence being less radiatively opaque. Fun.
Like many such posts, it has no comments. Which brings me on to DA’s plaint about not getting many comments (though he’s since cut it back). This is something that I intended to write a whole post about sometime, but I’m not sure I’ll get round to now. What gets comments, and what doesn’t, has precious little to do with intrinsic quality of the post. I’ve often thought that lower quality posts often get more comments, because there is something to say in reply. A perfectly formed posting that exhausts its subject is a joy to read, but not to reply to.
An earlier post at QS, Who is Patrick Moore?, probably deserves a wider readership for those who care about the political debate.
As does this one from which I’ve taken this image. People sometimes ask, “what proportion of warming is due to GHG’s”, and appear to expect an answer less than or equal to 100%; they generally can’t even begin to understand an answer greater than 100%.
JA is not very impressed with the “pause” or reactions to it. Which seems fair enough. See-also Breaking down the discrepancy between modeled and observed temperatures during the “hiatus” by Troy.
Oh, and finally: I’ve been making some attempts to sample the delights of on-line education available via the intertubes; it seemed a shame to ignore it all. I didn’t get very far with Turn Down the Heat: Why a 4°C Warmer World Must be Avoided on Coursera. I did a bit better with “An introduction to functional analysis” – I’d forgotten how breathtakingly beautiful and simple some of the basics are, like the abstract definition of a continuous function. But in the end, French from Duolingo seems to be getting on best.
