Creepy-crawly goodness

If you like invertebrates (and who doesn’t?) check out the Circus of the Spineless at Burning Silo.

I take a casual interest in insects and other invertebrates, but one thing you quickly realise is that they’re really hard. I first really appreciated this when, quite pleased with myself for recognising something as a ‘scorpionfly’, I tried to look it up in a book and discovered there are something like 28 species just of scorpionflies in the UK. And that’s relatively modest compared to the beetles and things. So I mainly stick to birds.

Since I’m on natural history, check out the dioramas at Pruned; it’s worth clicking through the links in that post as well.

Digital Library for the Decorative Arts and Material Culture

I was looking for an internet copy of Thomas Chippendale’s The Gentleman and Cabinet-Maker’s Director (which is a large collection of the most elegant and useful designs of household furniture in the Gothic, Chinese and modern taste) and found the University of Wisconsin’s Digital Library for the Decorative Arts and Material Culture. Not only does it have complete scans of the Chippendale, it also has Owen Jones’s The Grammar of Ornament, and lots of similar stuff like Temple of Flora, or, Garden of the botanist, poet, painter, and philosopher, The City and Country Builder’s and Workman’s Treasury of Designs, or, The art of drawing and working the ornamental parts of architecture, and A New Treatise on Flower Painting, or, Every lady her own drawing master: containing familiar and easy instructions for acquiring a perfect knowledge of drawing flowers with accuracy and taste: Also complete directions for producing the various tints.

And while I’m posting links to that kind of thing, I can’t resist adding one to Ernst Haeckel’s Kunstformen der Natur.

Bomb-sniffing flowers

Scientists in Denmark, the US and Canada have all been working on producing a genetically-engineered plant whose flowers will come up red instead of white in the presence of underground explosives. The idea, of course, is that you can use them to to test for the presence of landmines by dropping the seeds from the air and seeing what colour the flowers are when they come up.

Apart from the benefits if the technology works (and the rampant symbolism), this is the kind of project that the genetic engineers needed to come up with at the start of the technology to help sell it to the public. It would take a very hard person, however suspicious they were of science, to oppose a cheap new mine-detection technology.

Instead, of course, despite all the publicity about how GM products were going to end third-world hunger, reinvigorate medicine and who knows what else, the first major products were herbicide-resistent crops, allowing farmers to use even more toxic chemicals in the quest for ever-more intensive crop production. Personally I think that most of the opposition to GM food is incoherent, illogical and based entirely on prejudice, but I still can’t feel very positive about Round-up Ready soybeans.

Intellectuals, science, and the English Channel

Something Todd Swift said pointed me to an article in the Guardian about the lack of public intellectuals in Britain, written by Agnès Poirier, a French journalist working in London. It’s worth reading just for the culture-clash exhibited in the comments.

I noticed that the unspoken assumption, from both sides of the argument, was inevitably that an intellectual is a philosopher, a cultural theorist, a littérateur and not, for example, someone like Richard Dawkins.* So I started digging around for this quote from C. P. Snow’s The Two Cultures:

I remember G. H. Hardy once remarking to me in mild puzzlement, some time in the 1930s, “Have you noticed how the word “intellectual” is used nowadays? There seems to be a new definition which certainly doesn’t include Rutherford or Eddington or Dirac or Adrian or me? It does seem rather odd, don’t y’know.”

The point being, of course, that Hardy was a mathematician, Rutherford (no relation), Eddington and Dirac were physicists and Adrian was, Wikipedia informs me, a physiologist. Three of them won Nobel prizes. I remember being very struck by that quote when I first read it, and I still think Snow’s basic point about the wilful scientific ignorance of those in the humanities is a good one, even if some of the other things he says in the essay don’t stand up very well. Indeed Wikipedia led me to an essay by Roger Kimball titled “The two cultures” today, published in 1994 in the New Criterion. Kimball does an excellent and largely deserved demolition job on Snow’s essay, but in the process demonstrates exactly the depressing indifference to science that Snow was complaining about.

Snow’s argument operates by erasing or ignoring certain fundamental distinctions. He goes to a literary party, discovers that no one (except himself) can explain the second law of thermodynamics, and then concludes triumphantly: “yet I was asking something which is about the equivalent of Have you read a work of Shakespeare’s?” But, as Leavis notes, “there is no scientific equivalent of that question; equations between orders so disparate are meaningless.” The second law of thermodynamics is a piece of specialized knowledge, useful or irrelevant depending on the job to be done; the works of Shakespeare provide a window into the soul of humanity: to read them is tantamount to acquiring self-knowledge. Snow seems blind to this distinction.

“A piece of specialized knowledge, useful or irrelevant depending on the job to be done”. It just makes me want to cry. An insight into the fundamental workings of the universe reduced to a tool, a mathematical spanner, something of no possible interest to anyone who doesn’t need it to do a job. An indirect and second-hand insight into ‘the soul of humanity’ meanwhile is of such obvious value that it apparently goes without saying.

Such arrogance. Not just the intellectual arrogance that is willing to dismiss physics as just a tool for getting jobs done, but the arrogance to assume that ‘self-knowledge’ is of more value than the attempt to understand everything that exists. This isn’t an argument, it’s just an assertion of self-importance.

And yes, I do know that scientists are sometimes just as arrogantly dismissive of the value of the humanities. For the sake of even-handedness, and because it amuses me, here’s a quote from Dirac: “In science one tries to tell people, in such a way as to be understood by everyone, something that no one ever knew before. But in poetry, it’s the exact opposite.”

* Just a note to say that when I wrote this, Dawkins hadn’t yet published The God Delusion; he did write articles about atheism but was primarily known as a writer about evolutionary theory.

Adela reaumurella

How did we ever get along without the internet to help us scratch those little itches of curiosity? Admittedly, most of them seem to be along the lines of “What have I seen that bloke in before? Oh, I see, he was in [embarrassingly awful sitcom I couldn’t possibly admit to watching]”, but still.

Anyway, in the woods the other day I saw a curious-looking insect, and I just got round to looking it up. Starting by googling ‘day-flying moths uk’ and going from there I came up with Adela reaumurella:

(photo from the fabulous UKMoths website and © Charles Baker)

Like a lot of insects, no-one has bothered to give it an English name, but apparently there are a couple of families of moths with these characteristic antennae, and they’re generally referred to as ‘longhorn moths’. You can see the peculiar antennae above, but the picture doesn’t give the full effect, because when I saw them they were flying all around each other in a little swarm in the sun above a hornbeam, holding their antennae up in a V shape for maximum visibility.

I’m guessing the lady moths like a male with a long horn; that it was, in fact, a moth lek. A lek is where lots of males congregate to compete for female attention, either directly (i.e. by fighting for the best spot), or indirectly (displaying their plumage) or some combination. Insert your own Essex nightclub joke here.

It’s not quite as exciting as having lekking Black Grouse, Ruff, or even hermits (check out the video!), but I was pleased.

One example of lekking behaviour is actually very familiar, although people don’t generally realise what’s happening. On a summer evening, you’ll frequently encounter a swarm of midges flying round and round above a prominent object like a bush. If you walk past them, they often follow you and swarm above your head instead. They are in fact lekking. The males find a convenient landmark and form a swarm, waiting for the females to find them. I assume that in some situations it’s just more efficient to attract the females to one place and then compete directly with other males than it is to expend the energy finding the females individually. I have no idea how the female midges decide which males are the attractive ones.

The ternness of terns

George Szirtes discusses people’s need to identify things – flowers, birds – something he doesn’t share. Indeed he sets up (but slightly backs away from), an opposition between the botanist’s way of looking and the artists’s way. He ends like this:

Yet all the time I am aware that even an urban citoyen of the imagination should be able to tell a kingfisher by its silhouette as it flashes across a narrow stream or be able to name at least a hundred stars. One should be able to do that really, as well as trying to render the flashing sensation in language and learning to define the starness of stars.

I can’t help feeling that those people – the vast majority – who can’t distinguish a gull from a tern, a swallow from a swift, or a bee from a wasp or a hoverfly, are completely failing to appreciate the ternness of terns.

Being able to recognise something and distinguish it from superficially similar things seems absolutely central to any attempt to learn something about its thingness. The ability to attach a name is secondary to the process of coming to know a thing the way you know a familiar place or a friend.

Conversely, any birdwatcher could tell you that gaining some sense of a bird’s thingness, its inscape, is a key part of learning to identify it. Of course, being a prosaic bunch, they don’t call it ‘inscape’, they call it ‘jizz’. But if there’s a distinction between saying ‘I knew it was a tern because of its tern-like jizz’ and ‘I knew it was a tern because it had ternness’, it would take a better philosopher than me to elucidate it.
