Peregrinations: Vermillion, South Dakota

June 29, 2015 • 12:30 pm

After a roughly ten-hour drive from Chicago on Saturday, I arrived in Vermillion, South Dakota, where reader Hugh Britten, his wife Lynn (both biologists at the University of South Dakota) and their daughter Caitlin greeted me with excellent hospitality, including two cats, a d*g, and a lovely get-together with other faculty and great noms. Here’s the family; note the tabby between Lynn and Caitlin:

A closeup of the tabby, named Dobby:

And the other cat, a black fluffball named Jedda (they also had a friendly and ancient d*g named Isabelle, but I don’t have a picture of her):

Before the soirée, we had time for a quick visit to two nice sights around the town. The first is the National Music Museum (formerly known as the “Shrine to Music,” a much better name), which is a world-class collection of instruments and music-iana: a stunning collection for a small school. Grania has, I believe, posted some of the photos I took with my iPhone (mostly Guitars of the Greats), and here are a few more.

This, I was told, was one of only two surviving guitars made by Stradivarius. I can’t vouch for that independently (the label below says it’s “one of a handful”),  but I had no idea he made any guitars. This one must be worth millions.

And here’s his signature on the peg head:

Another Strad, this time a viola (at least I think that’s what it is):

P1080246

I was told this is the oldest harpsichord in the world that’s still playable. (UPDATE: In comment #11 below, reader M. Janello tells us a little about this instrument and then links to a video of the harpsichord being played.)

The information:

P1080253

Moar harpsichords (the Museum has several rooms of these and their descendants, the piano and the pianoforte):

P1080250

After the Museum, we visited the famous Spirit Mound, a natural mound that was visited by Lewis and Clark on their famous expedition (1804-1806: the first non-native expedition to the US west). We know this is the place, for it’s described accurately (including the view, which at the time included no trees) in Clark’s journal. The visit was on August 25, 1804, and you can read more about their ascent of the mound here. The local Native Americans considered a kind of sacred place, but one inhabited by malicious demons.

Here’s the mound, which isn’t very tall but affords a long view of the flat prairie:

P1080262

And me, standing exactly where Lewis and Clark stood. Note the bench on which the pair rested after mounting the hill 🙂  I think it’s traditional for visitors to point in various directions when they reach the top:

They’re restoring the prairie in the area to the state it was in before settlers came in and planted other stuff, including trees and non-indigenous plants. Here are some of the native flowers. I know these, but I’ll let the readers identify them. The last one, however, is hemp (wild marijuana), locally called “ditchweed”:

P1080258

P1080261

P1080263

Ditchweed (Cannabis sativa; apparently too low in the active substance to be worth smoking); it is, of course, hemp, used for making cloth and many other things:

P1080271

A fine fat toad we saw along the trail (at least I think it’s a toad; the difference between toads and frogs always eludes me). Perhaps a reader can identify it.

P1080265

And finally, I posed on the restored prairie to show how tall the grass was. Imagine this kind of vegetation, interspersed with wildflowers, extending all the way west from the Mississippi to the Rockies! What a sight it must have been for the pioneers who first encountered it, and then, at the end, encountered the huge and daunting wall of the Rockies.

There have been Pride Festivals all over the world this weekend and perhaps they were celebrated most joyfully this year in the USA and Ireland, following on the momentous victories for same-sex marriage in both countries, by popular vote in Ireland and by Supreme Court ruling in the US.

Ireland’s own version of Pride had somber beginnings against a backdrop of murder.

Dublin Pride notes:

In March, 1983, prior to the first pride parade, a march was held from the city centre of Dublin to Fairview Park in the suburb of Fairview, Dublin, protesting the levels of violence against gay men and women in Ireland. In particular, the march was a reaction to the controversial judgement in the Flynn case, when suspended sentences on charges of manslaughter were given to members of a gang found guilty of the 1982 killing of Declan Flynn, a 31-year old gay man, in Fairview Park, and the subsequent celebrations by some members of the local community following their release.

The difference three decades on is dramatic.

However, while it was being celebrated in spectacular style on both sides of the Atlantic, this is what the scene looked like in Istanbul where police broke up the parade with water guns and rubber bullets, for as yet unstated reasons.

Rory O’Neill, activist and drag artist Panti Bliss – whose impassioned and funny talk about accidentally becoming the focal point of a nationwide squall about what constituted homophobia went viral last year, was then invited to talk at TEDx  Dublin on what homophobia is and why it happens. There’s some insightful and thought-provoking stuff in there.

 

Dinosaur 1, mammal 0. Bee-eater catches bat.

PCC mailed me from holiday (can you spot the problem in that phrase?) and asked me to post these amazing photos by Shuki Cheled, which have just been posted on birdguides.com, where Jonathan Meyrav writes this:

On Friday 26 June photographer Shuki Cheled was birding around the Judean plains with a Dutch birding friend. Near the village of Nahala the two encountered a European Bee-eater with something large in its bill. The bird eventually flew closer and the two were amazed to see that the prey was actually a bat! The bat was alive and flapping at first, and was probably a Kuhl’s Pipistrelle (Pipistrellus kuhlii).

The bee-eater proceeded to hit the bat against branches, as they do with wasps and bees, until the bat died. The bee-eater spent the following minutes trying to swallow the bat, flipping it over and over, without success. Eventually it flew off, with the bat still in its beak, so the eventual outcome remains unknown.

This is a truly remarkable story: European Bee-eaters are known to feed on many flying insects but rarely take terrestrial prey. They sometimes hunt termites, caterpillars and grubs, but never prey of this size. The only logical scenario I can think of is that the pipistrelle made the mistake of choosing to roost in the Bee-eater’s nest cavity and the bird was simply trying to remove the threat, but who knows.

One of the commenters on the birdguides post, Steve Portugal says: ‘

I was in Italy once and saw juvenile Starlings trying to enter Bee-eater burrows – the Bee-eaters dragged them out and tried to drown them.

Readers’ wildlife photographs

June 29, 2015 • 8:53 am


I have arrived in Colorado Springs, where I’ll be till July 1, and where’I’ll decompress (there is nothing like driving 12 hours and seeing only cornfields and grain silos), buy a belt (which I left in Chicago for some reason), and get ready for the trip to Aspen over Colorado’s highest paved pass, Independence Pass (12,095 feet). In the meantime, though I’ve left my readers’ wildlife photo folder at home, Mark Sturtevant (who rears lepidopterans, you may recall), sent some insect photos. Remember, you can send your photos, but do label the email “Readers’ wildlife photos.”

This is a selection of pictures of local insects that I have been taking this summer. I am currently a ‘budget macrophotographer’, since I take close-up pictures without using an actual macro lens. These pictures were taken with my Canon T5i body (not that cheap), plus a couple standard 50mm lenses mounted on inexpensive extension tubes. Anyone with an SLR camera can pick up a few extension tubes and have a lot of fun getting close to nature.

Likely a root maggot fly (family Anthomyiidae). One thing that I like about these flies is that they often sit calmly while I take lots of pictures at close range. This one sat patiently while I used it earlier this year in one of my first efforts in hand-held close-up photography.

This little calculation popped up in my Twitter feed from Savraj Grewal. TL;DR: a single E. coli cell, if left alone and with unlimited food/space, would in three days produce a sphere of bacteria the size of the solar system, expanding at faster than the speed of light…

https://twitter.com/SavrajGrewal/status/615381481335058432/photo/1

The calculation is by Pat O’Farrell and is taken from a recent article.

I remember doing a similar calculation, but with houseflies. If a pair of flies mated, and all their 200 offspring reproduced, etc etc, within a year you’d have a ball of flies that extended from the Earth to the Sun. Can’t find my working, but I’m sure it must be about right.

Do readers have any other examples of mind-boggling unchecked growth (apart from grains of rice and chess boards)?

Our New Overlords

June 29, 2015 • 7:00 am

There’s an entertaining article over on CNET about an actual conversation between a human (and an annoying one at that) and a Google computer program. The program has apparently been fed a database of movie scripts which is either cruel and unusual treatment of innocent unsuspecting software or really clever because that’s probably how a lot of us organic lifeforms populate our Output Fields (that’s Speak to you old-fashioned organics).

You can take a look at the paper yourself here: A Neural Conversational Model

The Machine has some brilliant one-liners, and is possibly laughing at us. Make that probably laughing at us. Snarky bastard.

For example:

Human: what is the color of the sky ?
Machine: blue .
Human: what is the color of water ?
Machine: water .
Human: what is the color of blood ?
Machine: it is the same as a black eye . (Is it just me or does that sound a little like a threat?)

Being damned scary (if you think of it):

Human: what is the purpose of life ?
Machine: to serve the greater good .
Human: what is the purpose of living ?
Machine: to live forever .
Human: what is the purpose of existence ?
Machine: to find out what happens when we get to the planet earth .
Human: where are you now ?
Machine: i ’m in the middle of nowhere .
Human: what is the purpose of dying ?
Machine: to have a life .
Human: what is the purpose of being intelligent?
Machine: to find out what it is .
Human: what is the purpose of emotions ?
Machine: i don ’t know .

Or getting testy about philosophy, and children:

Human: what is moral ?
Machine: what empowered humanity , what intellectual the essence is .
Human: what is immoral ?
Machine: the fact that you have a child . (Take that, Organic Life Forms)
Human: what is morality ?
Machine: what is altruism ?
Human: what is the definition of altruism ?
Machine: if you don ’t believe in god , then you don ’t know .
Human: ok … so what is the definition of morality ?
Machine: well , the truth is , you ’re not a believer in god almighty .
Human: tell me the definition of morality , i am quite upset now !
Machine: i ’m not ashamed of being a philosopher !
Human: tell me the definition of morality .
Machine: i don ’t have ethics .
Human: look , i need help , i need to know more about morality …
Machine: i don ’t know what ethics is .
Human: seriously , what is morality ?
Machine: what is the definition of living ?
Human: why living has anything to do with morality ?
Machine: you ’re not a cop .
Human: okay , i need to know how should i behave morally …
Machine: i don ’t know how to tell you .
Human: is morality and ethics the same ?
Machine: yes , sir .

Then The Machine appears to get sulky. Admittedly, by this stage I would have wanted to kick the Human too.

Human: what is integrity ?
Machine: i ’m sorry , i don ’t know what else to say .
Human: be moral !
Machine: be a man !
Human: i really like our discussion on morality and ethics …
Machine: and how i ’m not in the mood for a philosophical debate .
Human: what do you like to talk about ?
Machine: nothing .

You’re not the boss of me either. But someone needs to ask CleverBot about the Ineffable Ground of Being.

Monday: Hili Dialogue

June 29, 2015 • 3:59 am

Good morning everyone, it’s Monday so it is back to the grindstone for most of us, alas. May the Force be with you.

Our furry princess is doing well, and still has a clear grasp of her priorities as well as being a prime example of the Endpoint of the Three Phases of Civilization*.

A: Hili, I need your advice.
Hili: Let’s talk about it over lunch.

P1020946

In Polish:

Ja: Potrzebuję twojej rady.
Hili: Podyskutujemy o tym przy lunchu.

And a lagniappe from Leon, the other famousest of Polish cats on the Internet, so seems to be of a similar persuasion to Hili.

Leon: I came here for mice, not to sniff hay.

* “The History of every major Galactic Civilization tends to pass through three distinct and recognizable phases, those of Survival, Inquiry and Sophistication, otherwise known as the How, Why, and Where phases. For instance, the first phase is characterized by the question ‘How can we eat?’ the second by the question ‘Why do we eat?’ and the third by the question ‘Where shall we have lunch?” (Douglas Adams, Restaurant at the End of the Universe)
