More of L’Aquila

Posted in Uncategorized with tags , , on October 12, 2014 by telescoper

At the risk of boring you all with even more pictures of L’Aquila, here are a few more pictures I took with my phone while out and about over the past week.

First, here’s the Gran Sasso Science Institute (GSSI) where our workshop is being held:


The following sites can all be found within a few minutes’ walk of the GSSI (which is itself just a few minutes from my hotel). In particular there is the historically important Romanesque church of Santa Maria di Collemaggio which dates back to the 13th Century. The façade looks in good nick, although there is evidence of recent repair. However, the back of the church collapsed completely during the 2009 Earthquake and is currently being rebuilt. There is also cracking and significant bowing of the wall on the left hand side, hence the supporting structures.

Excursion to Sulmona

Posted in Uncategorized with tags , , on October 11, 2014 by telescoper

I’m here on my own over the weekend so I decided to make the most of the lovely weather (it was a sunny 28° C today) and take a small excursion by train. The railway station at L’Aquila is situated on a branch line so the options from here are limited: up or down. I decided to take the “up” line to the town of Sulmona, which is 61km away by train. The ticket cost a mere €4.80 and though the train was a bit old, it was right on time in both directions. The journey time of an hour each way might seem a bit long, but the journey is through rather mountainous terrain and the service is a slow Regionale stopping service so I didn’t expect it to be a quick journey. On arrival I discovered that the Stazione Centrale is in fact pretty far from central but it was a pleasant walk of about half an hour into the small city centre.

Sulmona is famous for two things. One is that it is the birthplace of the poet Ovid who is  remembered by a fine bronze statue in the Piazza XX Settembre. The other famous thing is the Confetti di Sulmona, sugar-coated almonds coloured in such a way to look like oversized Smarties and presented in various disguises, e.g. as flower petals.

The town itself was almost totally destroyed by an earthquake in 1706. That’s a bit of a theme around these parts. You might think people would get fed up living in a place where natural catastrophes happen so regularly, but apparently not. Anyway, quite aside from the fact that many of the buildings are clearly of late eighteenth or early nineteenth century, which is not the case in L’Aquila, the reconstruction of Sulmona has made it a much airier place: the squares are larger and more open, and the streets wider. While the topography around L’Aquila is complex – the town itself sits on a hill surrounded by numerous local maxima, minima and saddle-points –  Sulmona sits in a broad flat plain on which the first and second derivatives behave in a much more sensible fashion.  I have to say that I have found L’Aquila quite oppressive at times during this visit. I don’t believe in ghosts of course, but there is so much evidence of destruction all around that it definitely has something of a haunted atmosphere. It was good to get away to a town whose wounds have healed.

A Brain Teaser from SWALEC

Posted in Uncategorized with tags , , on September 8, 2014 by telescoper

As I wend my way Brightonwards after a week in Wales, I thought I’d request your assistance in deciphering part of a letter I received from SWALEC, the company that supplies gas and electricity to my Cardiff residence.

If anyone out there can explain the logic that leads from a credit of £163.54 to an increase in my monthly payment – other than the obvious one that SWALEC are trying it on – I’d be most grateful!

Pallas’s Cat

Posted in Uncategorized with tags , on August 29, 2014 by telescoper

Too busy for a proper post today as I’ve got a lot to do before going off for a spot of annual leave. I’m therefore resorting to a standard ploy in such situation, posting a video of a cat. The short clip below features no ordinary cat, however. It’s an example of Pallas’s Cat, Otocolobus manul, a wonderful – but sadly endangered – creature which lives wild in the steppes of Central Asia. Here’s a fine specimen captured in a still photograph:


Although it appears very stocky because of its long fur, it’s actually no bigger than an average domestic cat.

The clip is a valuable reminder to us all that even the coolest and most dignified animals on Earth  can be hilarious when placed in an unfamiliar situation. This one has clearly just spotted a camera outside its lair….

As an “intellectual poseur” I couldn’t resist reblogging this piece …

Originally posted on The Dreamheron Chronicles:

Just this summer, Professor Amber Miller of Columbia University (appearing at the World Science Festival panel discussion on BICEP2), stated emphatically (and it seems, not required by the context of the discussion) that the cosmic blackbody is intact. Her taxpayer-funded high-tech research in the high frontier is riding on this assumption. (Watch the video from 1:07 to 1:09).

A video released last month by the learned society SPIE and filmed at NASA Goddard pointedly avers that the blackbody is fully intact, with 50 ppm accuracy.

And today this bit of public education from Professor Peter Coles of the University of Sussex (upon holding many consultations with mainstream colleagues at a conference on this very subject in Denmark) states:

The problem – the Achilles Heel of BICEP, so to speak – is that it operates at a single frequency, 150 GHz. That means that it is not possible for this experiment…
