Energy Inversion

Posted in Uncategorized with tags , , , , , on February 12, 2012 by telescoper

Like many people I’ve just received my gas and electricity bills. Unlike many, I can actually afford to pay them. My little terraced house is actually pretty easy to keep warm, even in the very cold weather we’ve had recently. I’m helped in that by the next door neighbours, who seem to have their heating on all the time thus warming one side of the house for me. I do occasionally put a few logs in the fireplace and treat myself to the comfort of the resulting blaze, but that’s not really necessary to keep warm, just me being a bit  bourgeois.

Coincidentally, the Independent recently ran an interesting article about fuel poverty and the inflated profits being made by the energy utilities in the United Kingdom.  The two are obviously connected, and it seems quite clear to me that the primary mechanism by which the public are being exploited is through the infamous ratchet. When wholesale fuel prices go up the regulator Ofgen allows the utilities to increase their retail energy prices accordingly. When the wholesale price comes down again, the retail price remains high and Ofgen does nothing. Next time wholesale prices rise, retail prices go up again, and so on. Prices to customers increase monotonically, with the inevitable result that the poor get squeezed and the companies’ profit spiral upwards.

There’s talk of the regulator getting tougher with the bastards companies concerned, but there’s been talk of that for ages. Nothing of any consequence ever happens. Meanwhile, vulnerable people, especially the elderly poor, die in the cold. It’s yet another sickening example of  the grossly distorted priorities of the world we live in.

I don’t claim to have an answer to all forms of capitalist exploitation, but reading my gas bill did give me an idea to help with this particular one. In common with many customers, my gas bill (from SWALEC in my case) is constructed in two parts: “standard energy” (which is quite expensive) and “discounted energy” (which is much cheaper, little over half the cost per kiloWatt-hour of the standard tariff). The way this works is the first 1000 kWh or so one uses are charged at the standard rate, then the additional energy consumption is charged at the discount rate.

This pricing system seems pretty normal, but it suddenly struck me when I got my bill as being completely the wrong way around. If one instead were charged the discounted rate initially and the higher rate for the excess, that would (a) benefit the poor, who presumably live in smaller houses than the rich and therefore use less energy to heat them, and (b) discourage profligate energy use beyond the switch-over point. Such a pricing system would give each user an “allowance” of cheaper energy, but charge them at a higher rate if they exceed it.

Inverting the tariff system in this way would  both help the most vulnerable and provide a real incentive for heavy users of energy to increase their efficiency. No point, though, in expecting the cartel of privatised energy suppliers to do something like that off their own bat. They’re doing very nicely out of the status quo and have no reason to change it. Dead pensioners don’t have much effect on their profits.

P.S. It also occurs to me that the £200 winter fuel payment currently paid by the government would be more efficiently targetted if it were passed on directly by energy utilities in the form of free energy to its elderly customers. I’d even make the case that they should pay it out of their own profits…

Out, Mad Colleague!

In order to develop further the problem-solving skills of students in the School of Physics & Astronomy at Cardiff University, it has been decided to list the entries in the Spring Semester module catalogue in the form of anagrams.

For example, here is the list for third year students doing basic courses in physics SHY PICS

PX3206      A CHEMIST’S TACTICAL SIN

PX3211       VASTLY DIMMED CAPACITANCE HASH

PX3226      MEDIC’S CROUTONS

PX3233      CRISPY HASSLE

PX3235      AN ANARCHY, SO MINDLESS NOTES

PX3237      ACCIDENTAL RAUNCHY SLIPPERS

while those taking courses involving ROMAN TOYS also have

PX3231       POSY ALCOHOLIC’S GYM

PX3212       SLITHERY SCALPS

Students doing  SCUM I also get to do

PX3214       SHUTS NOISY DENS

and DECIMAL students have

PX3234        A RUNT CALLED SODIUM

Students also have to do their JET CROP, of course…

Oh, and  I forgot that 3rd year students can also take

PX4215      PITY CHERISHES SAGGY HORN

I hope this clarifies the situation.

I Don’t Like Chocolate

Posted in Uncategorized on January 29, 2012 by telescoper

I was beginning to think I’m the only person in the Universe who doesn’t like chocolate, so I’m grateful to this blogger for showing me I’m not alone!

Yesterday Cadbury were “promoting” their revolting “Creme Eggs” on Twitter. These are particularly vile: sickly sugar-soaked globules of a mixture of pus and mucus, encased in solidified baby poo. Eat one and puke.

I don’t like them, you see.

I see that the Academic Journal Racket also applies to mathematics! I also see that WordPress has reinstated the “reblog” feature!

gowers's avatarGowers's Weblog

The Dutch publisher Elsevier publishes many of the world’s best known mathematics journals, including Advances in Mathematics, Comptes Rendus, Discrete Mathematics, The European Journal of Combinatorics, Historia Mathematica, Journal of Algebra, Journal of Approximation Theory, Journal of Combinatorics Series A, Journal of Functional Analysis, Journal of Geometry and Physics, Journal of Mathematical Analysis and Applications, Journal of Number Theory, Topology, and Topology and its Applications. For many years, it has also been heavily criticized for its business practices. Let me briefly summarize these criticisms.

1. It charges very high prices — so far above the average that it seems quite extraordinary that they can get away with it.

2. One method that they have for getting away with it is a practice known as “bundling”, where instead of giving libraries the choice of which journals they want to subscribe to, they offer them the choice between a large collection of…

Serious Brain Power – a reminder!

Posted in Uncategorized with tags on January 22, 2012 by telescoper

I’ve posted already about this initiative, but there’s no harm doing a bit of re-advertising on behalf of Cardiff University’s new recruitment campaign which has the slogan Serious Brain Power.  A major initiative is under way to attract high quality researchers to Cardff (either at Chair level for established academics or at the level of a Fellowship for those earlier in their careers)  across a range of academic disciplines, including STEM subjects.

In the School of Physics & Astronomy we’ve already appointed four new lecturers in Physics over the last year, and will also be joined by a new Professor of Experimental Physics next year, all independently of this scheme, but it would be great if we could attract even more excellent new people into the School via the new initiative; for an advert see here.

At fellowship level the positions  provide a greater degree of independence than a normal postdoctoral research assistantship, including the possibility to direct one’s own research programme. The number of  similar positions funded by research councils  is  dwindling owing to cutbacks in the research council budgets, making such a post a particularly valuable and attractive proposition.

Although this is a personal blog, and therefore not officially part of the recruitment campaign, it occurred to me that readers of this blog might well be interested in these opportunities, hence the reason for posting this message. Applicants for astronomy and cosmology would be welcomed,  by me at any rate! It’s a rare opportunity to join a Physics department that’s actually growing in size…

To find out more about the Fellowships and Chairs, see here. Feel free to contact me informally if you have any questions, and  please also feel free to pass this on to anyone you think might be interested!

Warning: This Blog is X-rated!

Posted in Uncategorized with tags , , , , on January 19, 2012 by telescoper

Most of you will have noticed that many important websites (including wikipedia) were offline yesterday in protest against SOPA (Stop Online Piracy Act) and PIPA (Protect Intellectual Property Act), two devices specifically designed to prevent the sharing of material via the internet. I’m among the many that think these acts are at best misguided and at worst downright sinister; see, e.g. here. They are probably also just the start of long battle to defend freedom of speech on the internet more generally. Those pushing ahead this repressive agenda are those with most to gain by controlling public access to information and most likely to want to write new laws to in order to avoid being held to account for violation of old ones. In other words, politicians.

Anyway, I recently discovered that I’ve become a victim of internet censorship myself. Apparently if you try to read this blog through some mobile internet connections a thing called Orange Safeguard pops up and tells you that this blog is only suitable to those aged 18 and over. If you can’t prove your age, access to the site is blocked.

Amused and, I have to say, slightly perturbed by this development, I went to the Orange site and found a list of reasons why a site might be X-rated. Here it is:

Anonymizers: These sites allow you to browse the Internet and access content anonymously.

Anorexia – Bulimia: Promoting and instigating eating disorders.

Gambling: Access to online gambling such as casinos and any other online services that let you place bets.

Chat: Where you chat in real time to people you don’t know.

Bombs: Explaining how to prepare, make, build and use explosives and explosive devices.

Dating: Websites for match-making where the user can meet other people – make friends, find a partner, etc.

Forums: Where you’re invited to take part in discussions on predetermined topics with people you don’t know.

Pornography: Websites with a pornographic or sexual content.

Racism: Sites promoting racist behaviour based on culture, race, religion, ideology, etc.

Sects: Websites on universally acknowledged sects. Within this category URLs are included on organizations that promote directly or indirectly: (i) group, animal or individual injuries, (ii) esoteric practices, (iii) content that sets a bad example for young children: that teaches or encourages children to perform harmful acts or imitate dangerous behaviour, (iv) content that creates feelings of fear, intimidation, horror, or psychological terror, (v) Incitement or depiction of harm against any individual or group based on gender, sexual orientation, ethnic, religious or national identity.

Violence: Containing openly violent content and/or that promote violence or defend it.

I’m not sure which of these I’ve fallen foul of. Is cosmology a sect? Or do the physics problems I’ve posted induce psychological terror? Who decided that this blog is for adults-only, and why? I’ve never been informed, although I have written to Orange in order to request this information…

..and that leads to the important question behind this amusing state of affairs. Who decides? Once we allow censorship to become commonplace, someone has to decide who can see what. That gives them, whoever they may be, far too much power.

If someone finds something I put on here offensive, they should have to tell me and explain why, not just arbitrarily terminate access. It’s the start of a journey that will take us into a very dark place indeed.

And another question. By blocking my blog, Orange Mobile is implying that it contains material belonging to the categories listed above. I don’t think it does. So can I sue Orange Mobile for libel?

The WordPress.com stats helper monkeys prepared a 2011 annual report for this blog.

Here’s an excerpt:

London Olympic Stadium holds 80,000 people. This blog was viewed about 360,000 times in 2011. If it were competing at London Olympic Stadium, it would take about 5 sold-out events for that many people to see it.

I’ve tried set this to appear just as the New Year comes in while I am out and about enjoying the revels. I hope I’ve set the WordPress scheduler correctly. I don’t think I’ll be in a fit state to fix it if not!

I’d just like to say thank you to everyone who has followed this blog over the last year, especially those who have commented on it either on the site or by private communication.

I wish you all a very Happy New Year and a 2012 that is full of Good Things.

Happy New Year!

Back from the North

Posted in Uncategorized with tags on December 28, 2011 by telescoper

After a nice Christmas break back in my home town of Newcastle I’m now back to Cardiff. The weather was a bit of a contrast after last year’s snow and ice, as it was unusually mild in the North East this year although a bit dark and blustery. I travelled there and back by train too, without any significant hitches either way, arriving on time on both journeys. It was a very restful holiday for me – which is just what I needed, if truth be told.

On boxing day we took a drive through the beautiful countryside of Northumberland where, as usual the winter weather produced some dramatic lighting effects. Although I only had my Blackberry with me I managed to get a snap of Warkworth Castle, which came out quite well, the castle looking brooding against the setting sun:


And a bit later on, over the moors, the wind clouds and sunbeams produced some ominous-looking patterns, which the little phone camera struggled to capture…

The portents turned out to be inaccurate, however, as Newcastle United managed to win their Boxing Day fixture, away against Bolton Wanderers, a team from the Midlands.

Anyway, I hope you all had as pleasant a festive period as I did. Now it’s all about preparing for the new year and new teaching term, and of course blogging will resume!

The Fall of the House of Usher

Posted in Uncategorized with tags , , , on December 17, 2011 by telescoper

It’s a strange tradition that the Christmas season tends to bring with it an appetite for ghost  stories and other tales of supernatural horror. It’s probably a reflection of a much earlier age when the winter was a harsh and dangerous time, during which food was scarce and survival through the winter meant huddling around a fire trying to stay warm. It seems natural to me that the kind of stories that would be told in such an environment would be of fear and foreboding. It’s not really a Christian tradition, therefore, but the legacy of a much older pagan one. Like Christmas itself, as a matter of fact.

Anyway, a few days ago at our little cosmology group Christmas night out the subject of horror films came up.  I’ve never been a particular aficianado of this genre, and I’m afraid most modern horror films are so formulaic that they bore me to tears. I do enjoy the classics enormously, however. James Whale’s 1931 Frankenstein, for example,  has to my mind never been bettered; a great film turned into a masterpiece by an unforgettably moving  performance by Boris Karloff. I think that’s a wonderful film, but I have to say I never found it particularly frightening, even as a child.

The first film I remember seeing that really terrified me was Roger Corman’s The Fall of the House of Usher starring the inimitable Vincent Price, a film based on a short story by Edgar Allan Poe. When I was around 8 or 9 I was once  left home alone on a Friday night by my parents. In those days the BBC used to show horror films late at night on Fridays and, against parental guidance, I decided to watch this one. It scared me witless and when my parents got home they found me a gibbering wreck. I don’t really know why I found it so scary – younger people reared on a diet of slasher movies probably find it very tame, as you don’t actually see anything particularly shocking – but the whole atmosphere of it really got to me. Here’s an example.

This reminds me that I need to get some replastering done in the new year….

Anyway, I’d be interested in hearing other suggestions for the most scariest film through the Comments box…
