Preoccupied with getting ready for my talk in Bath  I forgot t post an item pointing out that yesterday was the 25th anniversary of the launch of the Hubble Space Telescope. Can it really be so long?

Anyway, many happy returns to Hubble. I did manage to preempt the celebrations however by choosing the above picture of the Hubble Ultra Deep Field as the background fo the poster advertising the talk.

Anyway it went reasonably well. There was a full house and questions went on quite a while. Thanks to Bath Royal Literary and Scientific Institution for the invitation!

Dark Energy and its Discontents

Posted in Biographical, Books, The Universe and Stuff with tags , on April 24, 2015 by telescoper

Just time for a spot of gratuitous self-promotion. I shall be giving a public lecture tonight, Friday 24th April 2015, entitled Dark Energy and its Discontents, at the very posh-sounding Bath Royal Literary and Scientific Institution.
I am just finishing the slides for the talk, and packing some dark energy in my bag to use as a demonstration.
Here is the poster for tonight’s event, which explains all…

Perhaps I’ll see the odd reader of this blog there?

Mental Health at Work – to Declare or not to Declare?

Posted in Biographical, Mental Health with tags , on April 19, 2015 by telescoper

I couldn’t resist a comment on a recent article in the Times Higher  (written in response to an earlier piece expressing an opposite view). The question addressed by these articles is whether a member of University staff should be open about mental health issues or not. The latest comes down firmly on “no” side. Although I understand the argument, I disagree very strongly with this conclusion.

In fact I’ve taken this a bit further than just disclosing my problems to my employer; I’ve even blogged about them, both here and elsewhere. I also stood up in the University of Sussex Senate about two years ago and spoke about them there. That latter episode was in response to the attempts by some members of Senate to play down the extent of the violence and intimidation associated with a protest on campus that erupted into a full-scale riot on March 2013, accompanied by theft, vandalism and arson. Since violence is the root cause of my longstanding troubles I was incensed by the casual attitude some academics displayed about something that should never be tolerated. I don’t know whether my intervention had any effect on the discussion but I felt I had to make my point. It still troubles me, in fact, that the culprits have still not been brought to justice, and that some of them undoubtedly remain at large on campus even today.

Anyway, two full years have passed since then and I have received nothing but supportive comments from colleagues both in the School and among senior managers in the University.

When I applied for my current job at Sussex, it was just after I’d recovered from a serious breakdown. When I was offered the position, paperwork arrived that included a form on which to declare any health issues (including mental health). I have moved around several times in my career and have never made a declaration on such a form before, but this time I felt that I should especially because I was still taking medication then. I did wonder whether I might be declared unfit to take up a job that promised to have a fair share of stress associated with it. In the end, though, what happened was that I was put in touch with the Occupational Health department who offered their services if there was anything they could do to help. All these discussions were confidential.

I think it is very important that staff do declare problems with depression or other mental health issues. That’s the only way to be sure of getting the support you need. It’s also important for your colleagues to be able to put arrangements in place if you need to take some time off. On top of all that, employers need to learn how widespread such problems can be so they can try to deal with any factors that might exacerbate existing conditions, such as work-related stress.

Going back to the article in the Times Higher, though. I should say that I can understand the author’s reluctance. It took me twenty-five years so I am hardly in a position to criticise anyone! I was particularly struck by this section:

To disguise my illness, I try my best to be the very opposite of what depressed people are. I become the funniest, the smiliest and the most supportive colleague at work. At times, the performance succeeds and I feel a fleeting sense of being invincible. However, this feeling quickly dissipates and I am left feeling utterly alone, dark and lost. A colleague once said to me that she thought I was the most positive person she had ever met and that everyone enjoyed working with me. I couldn’t say anything to her in that moment. But if I was to speak my truth, it would have been to tell her that I was probably the darkest and saddest of her colleagues. That darkness frightens the hell out of me – so I keep it to myself.

That will ring very true to anyone who is living with mental illness; it becomes part of who you are, and it does mean that you find somethings very difficult or impossible that other people take for granted, no matter how effective your medication is. Putting on a brave face is just one way to avoid dealing with it, but it’s just a form of denial. Another common avoidance strategy is to make up fake excuses for absence from events that fill you with dread. I’ve done that a number of times over the years and although it provides short-term relief, it leaves you with a sense of shame at your own dishonesty that is damaging in the long run to your sense of self-worth and will only serve to give you a reputation for unreliability. The darkness can indeed be frightening but it does not follow that you should keep it to yourself. You should share it – not necessarily with friends and colleagues, who may not know how to help – but with compassionate and highly trained professional counsellors who really can help. It will also help your institution provide more and better assistance.

This is not to say that there isn’t a downside to being open about mental health issues. Now that my own genie is not only out of the bottle but all over the internet I do wonder what the future holds in store for my career beyond my current position. Then again I’m not at all sure what I want to happen. Only time will tell.

End of Term Balls

Posted in Biographical, Education with tags , , , , on April 18, 2015 by telescoper

I haven’t had time to post for the last couple of days because I’ve been too bust with end-of-term business (and pleasure). Yesterday (Friday) was the last day of teaching term and this week I had to get a lot of things finished because of various deadlines, as well as attending numerous meetings. It’s been quite an exhausting week, not just because of that but also because by tradition the two departments within the School of Mathematical and Physical Sciences at the University of Sussex, the Department of Mathematics and the Department of Physics & Astronomy, hold their annual Staff-Student Balls on consecutive days. When I arrived here just over two years ago I decided that I should attend both or neither, as to attend at only one would look like favouritism. In fact this is the third time I’ve attended both of them. Let no-one say I don’t take my obligations seriously.  It’s a tough job, but someone has to do it. Holding both balls so close together  poses some problems for a person of my age, but I coped and also tried to weigh them up relative to each other and see  which was  most impressive.

Actually, both were really well organized. The Mathematics Ball was held in the elegant Hilton Metropole hotel and the Physics one in the Holiday Inn, both on the seafront. As has been the case in previous years the Mathematics ball is a bit more refined and sedate, the Physics one a little more raucous. Also this year there was a very large difference in the number of people going, with over 200 at the Physics Ball and only just over half that number at the Mathematics one. In terms of all-round fun I have to declare the Physics Ball the winner last year, but both occasions were very enjoyable. I’d like to say a very public thank you to the organizers of both events, especially Sinem and Jordan for Mathematics and Francis for Physics. Very well done.

The highlight of the Physics Ball was an after-dinner speech by particle physicist Jon Butterworth, who has an excellent blog called Life and Physics on the Guardian website. I’ve actually been in contact with Jon many times through social media (especially Twitter) over a period of over six years, but we never actually met in person until last night. I think he was a bit nervous beforehand because he had never done an after-dinner speech before, in the end though his talk was funny and wise, and extremely well received. Mind you, I did make it easy for him by giving a short speech to introduce him, and after a speech by me almost anyone would look good!

Thereafter the evening continued with drinking and dancing. After a while most people present were rather tired and emotional.  I even think some might even have been drunk. I eventually got home about 2am, after declining an invitation to go to the after-party. I’m far too old for that sort of thing. Social events like this can be a little bit difficult, for a number of reasons. One is that there’s an inevitable “distance” between students and staff, not just in terms of age but also in the sense that the staff have positions of responsibility for the students. Students are not children, of course, so we’re not legally  in loco parentis, but something of that kind of relationship is definitely there. Although it doesn’t stop either side letting their hair down once in a while, I always find there’s a little bit of tension especially if the revels get a bit out of hand. To help occasions like this run smoothly I think it’s the responsibility of the staff members present to drink heavily in order to put the students at ease. United by a common bond of inebriation, the staff-student divide crumbles and a good time is had by all.

There’s another thing I find a bit strange. Chatting to students last night was the first time I had spoken to many of my students like that, i.e. outside the lecture  or tutorial. I see the same faces in my lectures day in, day out but all I do is talk to them about physics. I really don’t know much about them at all. But it is especially nice when on occasions like this students come up, as several did last night, and say that they enjoyed my lectures. Actually, it’s more than just nice. Amid all the bureaucracy and committee meetings, it’s very valuable to be reminded what the job is really all about.

 

P.S. Apologies for not having any pictures. I left my phone in the office on Friday when I went home to get changed. I will post some if anyone can supply appropriate images. Or, better still, inappropriate ones!

 

 

Interlude

Posted in Biographical, Uncategorized with tags , , on April 1, 2015 by telescoper

The University of Sussex is closing down for a week to allow people to take a breather around Easter weekend. After this afternoon’s staff meeting, I will heading off for a week’s holiday and probably won’t be blogging until I get back, primarily because I won’t have an internet connection where I’m going. That’s a deliberate decision, by the way….

So, as the saying goes, there will now follow a short intermission….

PS. The suitably restful and very typical bit of 1950s  “light” music accompanying this is called Pastoral Montage, and it was written by South African born composer Gideon Fagan.

 

Found in Translation…

Posted in Biographical, Books, Books, Talks and Reviews with tags on March 30, 2015 by telescoper

A nice surprise was waiting for me when I arrived at work this morning in the form of a parcel from Oxford University Press containing six copies of the new Arabic edition of my book  Cosmology: A Very Short Introduction. I think I’ve put them the right way up. I was a bit confused because they open the opposite way to books in English, as arabic is read from right to left rather than from left to right.

VSI-Arabic

Anyway, although I can’t read Arabic it’s nice to have these to put with the other foreign editions, including these. I still can’t remember whether the first one is Japanese or Korean…

…still, it’s interesting to see how they’ve chosen different covers for the different translations, and at least I know what my name looks like in Russian Bulgarian!

Remembering Erdös

Posted in Biographical with tags , , on March 17, 2015 by telescoper

This poster, advertising a forthcoming Summer School in honour of the famous mathematician Paul Erdös arrived this morning, so I thought I’d advertise it through this blog.

Erdos

In case you didn’t know, Paul Erdős (who died in 1996) was an eccentric yet prolific Hungarian mathematician who wrote more than 1000 mathematical papers during his life but never settled in one place for any length of time. He travelled constantly between colleagues and conferences, mostly living out of a suitcase, and showed no interest at all in property or possessions. His story is a fascinating one, and his contributions to mathematics were immense and wide-ranging, and I’m sure the conference in his honour will be fascinating.

A strange offshoot of his mathematical work is the Erdős number, which is really a tiny part of his legacy, but one that seems to have taken hold. Some mathematicians appear to take it very seriously, but most treat it with tongue firmly in cheek, as I certainly do.

So what is the Erdős number? It’s actually quite simple to define. First, Erdős himself is assigned an Erdős number of zero. Anyone who co-authored a paper with Erdős then has an Erdős number of 1. Then anyone who wrote a paper with someone who wrote a paper with Erdős has an Erdős number of 2, and so on. The Erdős number is thus a measure of “collaborative distance”, with lower numbers representing closer connections. I say it’s quite easy to define, but it’s rather harder to calculate. Or it would be were it not for modern bibliographic databases. In fact there’s a website run by the American Mathematical Society which allows you to calculate your Erdős number as well as a similar measure of collaborative distance with respect to any other mathematician. Also, a list of individuals with very low Erdős numbers (1, 2 or 3) can be found here. I did a quick poll around the Department of Mathematics here at the University of Sussex and it seems that the shortest collaborative distance among the staff belongs to Dr James Hirschfeld who has an Erdos Number of 2. There is a paper of his, with M. Deza and P. Frankl, Sections of varieties over finite fields as large intersection families, Proc. London. Math. Soc. 50 (1985), 405-425 and both Michel Deza and Peter Frankl have joint papers with Paul Erdős.

Given that Erdős was basically a pure mathematician, I didn’t expect first to show up as having any Erdős number at all, since I’m not really a mathematician and I’m certainly not very pure. However, his influence is clearly felt very strongly in physics and a surprisingly large number of physicists (and astronomers) have a surprisingly small Erdős number. Anyway, my erstwhile PhD supervisor Professor John D. Barrow emailed to point out that he had written a paper with Robin Wilson, who once co-authored a paper (on graph theory) with Erdős himself. That means that John’s Erdős number is now 2, mine is consequently 3 (unless, improbably, I have unkowingly written a paper with someone who has written a paper with Erdős). Anyone I’ve ever written a paper with has an Erdős number no greater than 4; they of course may have other routes to Erdős than through me.

Anyway, none of that is important compared to the real legacy of Erdős, which is his mathematical work. I’m sure the Summer School will be both rewarding and enjoyable!

Essays in Physics

Posted in Biographical, Education with tags , , , , , , on March 6, 2015 by telescoper

In the course of a rare episode of tidying-up in my office I came across this. You can click on it to make it bigger if it’s difficult to read. It was the first paper of my finals examination at the University of Cambridge way back in 1985. Yes, that really was thirty years ago…

wpid-wp-1425648226410.jpeg

As you can probably infer from the little circle around number 4, I decided to write an Essay about topic 4. I’ve always been interested in detective stories so this was an easy choice for me, but I have absolutely no idea what I wrote about for three hours. Nor do I recall actually ever getting a mark for the essay, so I never really knew whether it really counted for anything. I do remember, however, that I had another 3-hour examination in the afternoon of the same day, two three-hour examinations the following day, and would have had two the day after that had I not elected to do a theory project which let me off one paper at the end.

I survived this rigorous diet of examinations (more-or-less) and later that year moved to Sussex to start my DPhil, returning here couple of years ago as Head of the same School in which I did my graduate studies. To add further proof that the universe is cyclic, this year I’ve taken on the job of being External Examiner for physics at the University of Cambridge, the same place I did my undergraduate studies.

Anyway, to get back to the essay paper, we certainly don’t set essay examinations like that here in the Department of Physics & Astronomy at the University of Sussex and I suspect they no longer do so in the Department of Physics at Cambridge. I don’t really see the point of making students write such things under examination conditions. On the other hand, I do have an essay as part of the coursework in my 2nd Year Theoretical Physics module. That may seem surprising and I’m not sure the students like the idea, but the reason for having it is that theoretical physics students don’t do experimental work in the second year so they don’t get the chance to develop their writing skills through lab reports. The essay titles I set are much more specific than those listed in the paper above and linked very closely to the topics covered in the lectures, but it’s still an opportunity for physics students to practice writing and getting some feedback on their efforts. Incidentally, some of the submissions last year were outstandingly good and I’m actually quite looking forward to reading this year’s crop!

Farewell, Mr Spock

Posted in Biographical, Television on February 27, 2015 by telescoper

I was very sad to hear this afternoon of the death, at the age of 83, of actor Leonard Nimoy. Although he did a great many other things in a long and varied career, Leonard Nimoy will of course be remembered most fondly for his role as Mr Spock, Science Officer of the USS Enterprise, in Star Trek.

I was both fascinated and inspired by Mr Spock when I was young, so Leonard Nimoy’s death is like the loss of an old friend. I’m sure I’m not the only scientist of my generation who is feeling that way today. Mr Spock represented the outsider in all of us.
