Following on from a provocative post I wrote a couple of weeks ago on this blog (which was subsequently reblogged by the Times Higher), I was contacted by Paul Crowther who sent me a copy of the slides used by Peter Main of the Institute of Physics in a talk in May 2015 on the subject of Widening Participation in Physics. With Peter Main’s permission I’m sharing those slides here as a service to the Physics community. There’s a lot of interesting information in these slides, which I think many UK physicists would be interested in.

Posted in Education, Science Politics with tags HEFCE, Higher Education, REF, research, Research Excellence Framework, Universities on September 9, 2015 by telescoperThis morning, the Minister for Universities, Jo Johnson, made a speech in which, among other things, he called for research funding to be made simpler. Under the current “dual funding” system, university researchers receive money through two main routes: one is the Research Excellence Framework (REF) which leads to so-called “QR” funding allocations made via the Higher Education Funding Council for England (HEFCE); and the other is through research grants which have to be applied for competitively from various sources, including the Seven Research Councils.
Part of the argument why this system needs to be simplified is the enormous expense and administrative burden of the Research Excellence Framework. Many people have commented to me that although they hate the REF and accept that it’s ridiculously expensive and time-consuming, they didn’t see any alternative. I’ve been thinking about it and thought I’d make a suggestion. Feel free to shoot it down in flames through the box at the end, but I’ll begin with a short introduction.
Those of you old enough to remember will know that before 1992 (when the old `polytechnics’ were given the go-ahead to call themselves `universities’) the University Funding Council – the forerunner of HEFCE – allocated research funding to universities by a simple formula related to the number of undergraduate students. When the number of universities suddenly increased this was no longer sustainable, so the funding agency began a series of Research Assessment Exercises to assign research funds (now called QR funding) based on the outcome. This prevented research money going to departments that weren’t active in research, most (but not all) of which were in the ex-Polytechnics. Over the years the apparatus of research assessment has become larger, more burdensome, and incomprehensibly obsessed with short-term impact of the research. Like most bureaucracies it has lost sight of its original purpose and has now become something that exists purely for its own sake.
It is especially indefensible at this time of deep cuts to university core funding that we are being forced to waste an increasingly large fraction of our decreasing budgets on staff-time that accomplishes nothing useful except pandering to the bean counters.
My proposal is to abandon the latest manifestation of research assessment mania, i.e. the REF, and return to a simple formula, much like the pre-1992 system, except that QR funding should be based on research student (i.e. PhD student) rather than undergraduate numbers. There’s an obvious risk of game-playing, and this idea would only stand a chance of working at all if the formula involved the number of successfully completed research degrees over a given period .
I can also see an argument that four-year undergraduate students (e.g. MPhys or MSci students) also be included in the formula, as most of these involve a project that requires a strong research environment.
Among the advantages of this scheme are that it’s simple, easy to administer, would not spread QR funding in non-research departments, and would not waste hundreds of millions of pounds on bureaucracy that would be better spent actually doing research. It would also maintain the current “dual support” system for research, if that’s a benefit.
I’m sure you’ll point out disadvantages through the comments box!
The Essence of Cosmology is Statistics
Posted in The Universe and Stuff with tags George McVittie, statistics, Third Berkeley Symposium on Mathematical Statistics and Probability on September 8, 2015 by telescoperI’m grateful to Licia Verde for sending this picture of me in action at last week’s conference in Castiglioncello.
The quote is one I use quite regularly, as the source is quite surprising. It is by George McVittie and appears in the Preface to the Proceedings of the Third Bekeley Symposium on Mathematical Statistics and Probability, which took place in 1956. It is surprising for two reasons. One is that McVittie is more strongly associated with theoretical cosmology than with statistics. In fact I have one of his books, the first edition of which was published in 1937:
There’s a bit in the book about observational cosmology, but basically it’s wall-to-wall Christoffel symbols!
The other surprising thing is that way back in 1956 there was precious little statistical information relevant to cosmology anyway, a far cry from the situation today with our plethora of maps and galaxy surveys. What he was saying though was that statistics is all about making inferences based on partial or incomplete data. Given that the subject of cosmology is the entire Universe, it is obvious we will never have complete data (i.e. we will never know everything). Hence cosmology is essentially statistical. This is true of other fields too, but in cosmology it is taken to an extreme. George McVittie passed away in 1988, so didn’t really live long enough to see this statement fulfilled, but it certainly has been over the last couple of decades!
P.S. Although he spent much of his working life in the East End of London (at Queen Mary College), George McVittie should not be confused with the even more famous, or rather infamous, Jack McVitie.

Posted in Music with tags BBC Radio 3, Cello Suites, Johann Sebastian Bach, Promenade Concert, Yo-Yo Ma on September 7, 2015 by telescoperI stayed in on Saturday night especially to listen to a very special promenade concert live on BBC Radio 3 during which renowned cellist Yo-Yo Ma played all six of the Suites for unaccompanied Cello by Johann Sebastian Bach. It was an absolutely brilliant concert which you can, if you missed it, or even if you didn’t, download for the next month here. The whole thing runs for over two and a half hours, but I didn’t move from my seat once.
I’ve loved all these pieces from the moment I first heard them. How Bach manages to conjure up such a vast range of melodic and rhythmic possibilities using just the one instrument is almost miraculous. Despite using very few chords, they manage to explore the harmonic domain too. Part of what makes them so special is the instrument itself – its earthy sound, complete with occasional growls and scrapes, emphasizes how this sublime music is somehow at the same time deeply human, somehow connecting the listener to something from far beyond the mundane world we normally inhabit. I’m not a religious man, but listening to music like this is a spiritual experience for me.
Do listen to the whole concert if you can, but if you can’t here’s a short taster (recorded elsewhere). This is the Prelude to the 1st Suite, the first page of which is here:
If you look at the sheet music you might be forgiven for thinking that it is just a dry exercise in playing across the strings. Listen to it come to life, however, and you’ll quickly realise that you were wrong. The ending of this prelude always sends shivers down my spine.
I know these suites have been transcribed for other solo instruments, such as the flute, but listening to them on Saturday I wondered if they had been transcribed for my favourite earthy and growly instrument, the tenor saxophone. In fact they have; you can hear an example here. One problem that struck me immediately is that saxophonists have to pause for breath! Anyway, I must get a copy of the transcription and have a go at learning it, though I think it would take a Sonny Rollins or John Coltrane to do them justice!

The Day of Daltonism
Posted in History with tags Colour Blind Awareness Day, John Dalton on September 6, 2015 by telescoperHaving a quick look at Twitter this morning as I drank my coffee I discovered that it is the birthday of the English scientist John Dalton, who was born on 6th September 1766. Dalton is most famous in the United Kingdom for his work on chemistry and physics, but somewhat less so for his pioneering studies of colour blindness. I didn’t know until today, in fact, that the birthday of John Dalton, who was himself colour blind, is Colour Blindness Awareness Day so I thought I’d do a quick post to mark the occasion. You might also be interested in this guest post on the subject of colour and colour perception.
Here’s a test for some of the main types of colour blindness – can you read the numbers?
Colour blindness comes in different forms and affects a significant fraction of the population, with a much higher rate of occurrence in males (up to 1 in 10 in some groups) than in females (about 1 in 200). It also varies significantly across different populations, with particularly low rates for, e.g., Fijian males (0.8 %) and much higher frequencies among, e.g. Russian males (9.2%). I am not colour-blind myself, but I know several colleagues who are. In fact at the meeting I was at last week, when one speaker decided to show two different sets of results on a graph by plotting one in red and the other in green, there were howls from several in the audience who couldn’t tell them apart. It’s very easy to make careless mistakes like this in preparing lecture materials when it takes only a small effort to make them suitable for all. I urge colleagues who teach to remember that if they are 100 men in the audience the likelihood is that there will be around 8 to 10 who are colour blind.
Thinking about this makes you realise how many maps and other designs rely on full colour perception for their effect. I’ve previously celebrated the London Underground map as an excellent example of graphic design, but it must be a nightmare to a person who is colour blind!
Last week I gave a short speech at the workshop to celebrate Sabino Matarrese’s 60th birthday, in the course of which I mentioned the late Francesco Lucchin, who first invited to Italy to work with the Padova group (of which Sabino was a member) back in the early 90s. Francesco and I ended up writing a book together and during the course of working on that he told me that he was “daltonic”. I later found out that this word does exist in English, but it is not in common usage as a word meaning “colour blind”. In fact the standard word in Italian for “colour blind” is “daltonico” and there are many other variants in other European languages, such as the French “daltonien”. It’s very curious that Dalton’s name is so strongly associated with colour blindness across the European continent but not in the country of his birth. I wonder why?
By the way, if I understand correctly, the English word “daltonic” refers to a specific form of red/green colour blindness called deuteranopia, whereas the foreign variants can refer to any form of colour blindness.
Anyway, must wrap it up there. I have to mark some resit examinations which, according to the instructions, should be done in red ink by the first marker and in green ink by the second marker…
Follow @telescoperFrom here to Astragalo
Posted in Biographical, History with tags Astragalo, Castiglioncello, dice, Gambling, Italy on September 5, 2015 by telescoperNow that I’m back to the relatively autumnal setting of Brighton, I can’t help reflecting on last week’s meeting. On Monday evening I attended a cocktail party in a very pleasant bar in Castiglioncello overlooking the sea. Sunset views are something of a speciality from this location:
Anyway, the name of the place we were in was Astragalo. I checked and, as I suspected, this the Italian word for astragalus, which has an approximately tetrahedral shape. Astragalus is also a kind of plant, which is perhaps more likely to be associated with the name of a seaside bar, but that spoils the connection I wish to make with probability theory, a topic that came up regularly during the conference I was attending, so I’ll ignore it.
Nowadays gambling is generally looked down on as something shady and disreputable, not to be discussed in polite company, or even to be banned altogether. However, the formulation of the basic laws of probability was almost exclusively inspired by their potential application to games of chance. Once established, these laws found a much wide range of applications in scientific contexts, including my own field of astronomy. The astragalus provides a very early example.
Gambling in various forms has been around for millennia. Sumerian and Assyrian archaeological sites are littered with examples the astragalus (or talus bone). This is found just above the heel and its roughly tetrahedral shape (in sheep and deer at any rate) is such that when it is tossed in the air it can land in any one of four possible orientations; it’s fairly similar in fact to the four-sided dice used in some role-playing games. The astragalus can be used to generate “random” outcomes and is in many ways the forerunner of modern six-sided dice. The astragalus is known to have been used for gambling games as early as 3600 BC.

Unlike modern dice, which began to appear around 2000BC, the astragalus is not quite symmetrical, giving a different probability of it landing in each orientation. It is not thought that there was a mathematical understanding of how to calculate odds in games involving this object or its more symmetrical successors (right).

The Best of Times
Posted in Literature, The Universe and Stuff with tags A Tale of Two Cities, Charles Dickens, Cosmology on September 3, 2015 by telescoperWell, I made it to Pisa Airport in time to sample the Club Europe lounge, which offers free wifi access (as well as other luxuries). It seems I have a bit of time before my flight so thought I’d do a quick post about this morning’s events. I had the honour to be asked, along with Rocky Kolb, to deliver the concluding remarks for the meeting I’ve been at since Monday. Rocky and I had a quick discussion yesterday about what we should do and we agreed that we shouldn’t try to do a conventional “summary” of the workshop, but instead try something different. In the end we turned to Charles Dickens for inspiration and based the closing remarks on the following text:
IT WAS the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way…
This is of course part of the famous opening paragraph of Book 1 of A Tale of Two Cities.
The idea was to use the text to discuss different perspectives on the state of the Universe, or at least of cosmology. For example, the fact that we now have huge amounts of cosmological data might lead you to view that this is the “the best of times” for cosmology. On the other hand, this has made life much harder for theorists as everything is now so heavily constrained that it is much more difficult to generate viable alternative models than it was thirty years ago. We also now have a standard cosmological model which some physicists believe in very strongly, whereas others are much more skeptical. This the “epoch of belief” for some but the “epoch of incredulity” for others. Now that the field is dominated by large collaborations in which it is hard for younger researchers to establish themselves, is this a “winter of despair” or do the opportunities presented by the new era of cosmology offer a “spring of hope”.
I haven’t got time to summarize all the points that came up, but it was fun acting as a “feed” for Rocky who had a stream of amusing and insightful comments. There aren’t any “right” or “wrong” answers of course, but it seemed to be an interesting way to get people thinking about where on the “best of times/worst of times” axis they would position themselves.
My own opinion is that cosmology has changed since I started (thirty years ago) and the challenges by the current generation are different from, and in many ways tougher than, those faced by my generation, who were lucky to have been able to learn quite a lot using relatively simple ideas and techniques. Now most of the “easy” stuff has been done, but solving difficult puzzles is immensely rewarding not only for the scientific insights the answers reveal, but also for their own sake. The time to despair about a field is not when it gets tough, but when it stops being fun. I’m glad to say we’re a long way from that situation in cosmology.

Last Day Blues
Posted in Biographical on September 3, 2015 by telescoperWell, here I am. My last day in Castiglioncello. I’m all packed and ready. Just time for a quick post before I go down to breakfast overlooking the sea..
After breakfast I have to check out and then head up to the conference for the final session, concluding remarks, farewells and all that. Then I have to get back to Pisa for the flight home.
It’s been a fun meeting, but all too brief. I wouldn’t have minded staying here a lot longer, because that would have given me the chance to have a proper holiday before term starts, but now it’s just a week before our new students arrive and it will be back once more into the regular cycle of academic term.
