LGBTQ+ STEMinar 2020 – The Conference Photograph!

Posted in Biographical, LGBT with tags , , , on February 17, 2020 by telescoper

Regular readers of this blog – both of them – will be aware that last month I attended the 2020 LGBTQ+ STEMinar at the University of Birmingham. This was fifth of these and the largest one of these do far, with around 250 participants. Anyway, I’ve just received delivery of the conference photo!

You’ll see me on the extreme left about half way up. Of course there are fewer than 250 in the photograph: not everyone wanted to be in it (for a variety of reasons).

Anyway, the next one of these will be in 2021 in Oxford where, I am told, there is also a university.

LGBTQ+ STEMinar 2020

Well I made it to Birmingham (after getting up at 3.30am!) and to the Leonard Deacon Lecture Theatre in the School of Medicine at the University thereof for this year’s LGBT+ STEMinar (the 5th of a series that started in 2016).

This is the largest one of these do far, with around 250 participants, and an impressive array of sponsors:

One of the great things about the LGBTSTEMeminar (apart from the feeling of being amongst ‘family’) is the opportunity to hear talks about fields other than your own, which I am enjoying very much.

Ooh. I forgot to mention that next year’s event will also be in the Midlands, at Oxford University.

Exams and Anniversaries

Posted in Biographical, Education, Maynooth with tags , , , on January 9, 2020 by telescoper

Tomorrow (10th January)  is the start of our mid-year examination period here at Maynooth University. It’s therefore a good opportunity to send a hearty “good luck” message to all students about to take examinations, especially those who are further on in their courses for whom these papers have greater importance. In particular I’d like to send my best wishes to students on my fourth-year module on Astrology Astrophysics and Cosmetics Cosmology, whose paper is tomorrow.

On the equivalent day last year I reflected on examinations and in particularly on the fact that the system of education both here in Ireland and in the United Kingdom places such a great emphasis on examination and assessment compared to learning and understanding.

Also on the equivalent day yesterday I was about to travel to London to attend my first LGBT+STEMinar at the Institute of Physics in London. Tomorrow I’ll be doing a similar thing, getting up at stupid o’clock
to travel to Birmingham for the 2020 event. The main difference this year (apart from the change of venue) is that I’m not giving a talk this time. This is good news for me (because it means I can relax a bit more) and for the attendees (because they don’t have to listen to me rambling on like they did last year).

I won’t be able to stay to the end of the LGBT+STEMinar, however, as I have to get to London. As I have mentioned previously here, 2020 marks the bicentenary of the Royal Astronomical Society:

According to the brief history published on the RAS website:

The ‘Astronomical Society of London’ was conceived on 12 January 1820 when 14 gentlemen sat down to dinner at the Freemason’s Tavern, in Lincoln’s Inn Fields, London. After an unusually short gestation the new Society was born on 10 March 1820 with the first meeting of the Council and the Society as a whole. An early setback, when Sir Joseph Banks induced the Duke of Somerset to withdraw his agreement to be the first President, was overcome when Sir William Herschel agreed to be the titular first President, though he never actually took the Chair at a meeting.

To be precise, the Society only became the `Royal Astronomical Society’ in 1831 when it was granted a Royal Charter by William IV, but its roots go back to 1820.

It’s not only the Royal Astronomical Society that has survived and prospered for two hundred years. The group of `gentlemen’ who met for dinner in January 1820 has also carried on in the form of the RAS Club which is, of course, older than the RAS itself. The Dining Club always meet on the second Friday of the month, which means that tomorrow is the closest date to that very first meeting. There will therefore be a special club dinner tomorrow night, with more guests than usual. I’m looking forward to it a lot, actually, although I’m slightly apprehensive about the fact that I’ll be relying on the train to get me there in time!

LGBT+ STEMinar – Notes on my Keynote

Posted in Biographical, LGBT, The Universe and Stuff with tags , , , on January 12, 2019 by telescoper

I’m in a hotel near King’s Cross having had my Full English and with an hour or so before I have to check out and trek to Heathrow for my flight back to Dublin.

First things first. I promised a few people yesterday at the LGBT STEMinar that I would post the slides I used in my Keynote talk yesterday so here you go:

And here are a few pictures of me in action. I got all these from Twitter so apologize for not giving due credit to the photographers. My timeline was very crowded yesterday!

What I tried to do in the talk was to discuss the theme of progress over the last thirty years, both in my area of research (cosmology, specifically the large-scale structure of the Universe) and in the area of LGBT+ rights.

I started with my time as a graduate student at Sussex. One of the first things I did during `Freshers Week’ at when I started there was to join the GaySoc (as it was called) and I gradually became more involved in it as time went on. Over the five years I was at Sussex, `Gaysoc’ became `Lesbian and Gay Soc’ but a move to recognize bisexual people in the title was voted down, by quite a large margin. Inclusivity was (and still isn’t) a given even among marginalized groups. Biphobia and transphobia are still very much around.

Initially I kept my sexual orientation separate from my academic life and wasn’t really all that open in the Department in which I worked. My decision to change that was largely because of things going on in the outside world that convinced me that there was a need to stand up and be counted.

One of these was the AIDS `panic’ exacerbated by the Thatcher Government’s awful advertising campaign, an example of which you can see above. It was a very frightening time to be gay, not only because of the fear of contracting AIDS oneself but also because of the hostility that arose as a reaction to the `gay plague’. I’m convinced that this campaign led directly to a great deal of the violence that was inflicted on gay people during this time, including myself.

The second thing that made me want to come out was the Local Government Act (1988), which included the now infamous Section 28 (above). This was the subject of the first political demonstrations I ever attended. We failed to stop it becoming law, which was what we had wanted to do, but one positive that came out of this was that it did galvanize a lot of people into action, and the law was eventually repealed.

Anyway, I just got fed up of hearing people making ill-informed generalisations during this time. Rather than make a big public statement about being gay, I just resolved to not let such comments pass. I think it only took a few intercessions in the tea room or Falmer Bar for it to become widely known in the Department that I was gay. That was how I came out in astrophysics, and thereafter almost everyone just seemed to know.

So that was the eighties. If somebody had told me then that in thirty years the United Kingdom would have legalized same-sex marriage I would just have laughed. That wasn’t even really being discussed by the LGBT+ community then.

Anyway, back to the talk. What I then tried to do – actually for most of the presentation – was to outline the progress that has been made over the last thirty years in cosmology. When I started in 1985 there was hardly any data. There were some small redshift surveys of the order of a thousand galaxies, but my thesis was supposed to be about the pattern of fluctuations in the cosmic microwave background and there were no relevant measurements back then. I had to rely on simulations, as I mentioned here a few days ago.

Over the years there has been tremendous progress, especially with the accumulation of data enabled by improvements in observational technology. Theory has moved on to the extent that we now have a standard model of cosmology that accounts for most of this data (at least in a broad-brush sense) with just six free parameters. That’s a great success.

This rapid progress has led some to suggest that cosmology is now basically over in the sense that we have done virtually everything that we’ll ever do. I disagree with this entirely. The standard model contains a number of assumptions (general relativity, cold dark matter, a cosmological constant, and so on) all of which should be questioned. In science every answer leads to new questions and all progress to new challenges. If we ever rest on our laurels the field will stagnate and die. Success should never lead to complacency.

So then in the talk I returned to LGBT+ rights. Some (straight) people have said to me that now that we have equal marriage then it’s basically all done, isn’t it? There’s now no discrimination. You can stop talking about LGBT+ matters and `just be a scientist’.

That, I’m afraid, is bollocks. We have equal marriage but, though welcome, by no means represents some sort of utopia. Society is still basically a patriarchy, configured in a way that is profoundly unfair to many groups of people, so there are still many challenges to be fought. Unless we keep pushing for a truly inclusive society there is a real danger that the rights we have won could easily be rolled back. This is no more over than cosmology is over. In fact, you could really say that it’s really just the start.

The 2019 LGBT+STEMinar

Posted in Biographical, LGBT, The Universe and Stuff with tags , on January 11, 2019 by telescoper

I’m just back in my hotel after an evening at the Royal Astronomical Society Club Dinner which I went to straight from today’s LGBT+STEMinar at the very nice new Institute of Physics building on Caledonian Road near King’s Cross. This is what it looked like when I arrived this morning:

I enjoyed the LGBT+ STEMinar very much indeed. There was a huge range of talks by a wonderfully diverse crowd of speakers, on topics ranging from nuclear waste, parasites in wood mice, glaciology, quantum optics, the evolution of island finches, bacterial pathogenesis, gamma-ray bursts and machine learning in astrophysics.

I particular enjoyed the talk by Niamh Kavanagh from the Tyndall Institute in Cork who handed out home-made filters to give herself a rainbow effect:

I was delighted and relieved that my keynote talk and the end of the day seemed to go down quite well, at least judging by the comments I found in my Twitter feed just now. Here’s a picture I found there!

I’ll post the slides from my talk and perhaps a few other comments about it tomorrow, after I’ve had a good night’s sleep. But I won’t delay in thanking the organisers, especially Angela Townsend, for making this such a special day.

Cosmological Simulations down Memory Lane

Posted in Biographical, LGBT, The Universe and Stuff with tags on January 8, 2019 by telescoper

On Friday I have to be in London to give a keynote talk at this year’s LGBT+ STEMinar, which is taking place at the new Institute of Physics Building near King’s Cross. I’ve been struggling to think what to say but a conversation this afternoon with some of our PhD students gave me an idea. I won’t spoil it for those going to the event by giving too much detail away, but it involves going over the past 30 years of cosmology and LGBT+ rights alongside each other, pointing out that in both areas there has been great progress but there is also still very much to do.

Anyway, in the course of this I had a look at my thesis (vintage 1988) and came up with the following pictures, in glorious monochrome:

You can click on them to make them bigger. When I started my graduate studies in 1985 my thesis was supposed to be about the statistical analysis of the cosmic microwave background. The problem was that way back then there weren’t any measurements, so I had to make simulations to test various analysis methods on. The above images are examples that ended up in a published paper.

You have no idea what a pain it was to make these images. I had very limited access to a graphics terminal so I had to send these to a special printer in the computer room  (which was behind closed doors and an airlock) and then wait (sometimes for days) for the operators to process the files and produce a the printout. If they came out wrong the process had to be repeated. It was all frustratingly slow as my programs were quite buggy, at least to begin with.

For those of you interested, these simulations were made using a (two-dimensional) Fast-Fourier Transform method, using a pseudo-random number generator to set up appropriate amplitudes and phases for the Fourier modes. The only even remotely clever bit was to find a way of generating Gaussian and non-Gaussian maps with the same two-point correlations.

In all it took me several months of work to complete the work that went into that paper (which was essentially a thesis chapter). When I look back on it I think if I’d been cleverer – and had a decent graphics screen like you find on a modern PC – I could have done it all in a couple of days!

And now, of course, we have real data as well as simulations!

My point is that things that seem very difficult at the time often look extremely easy in retrospect. And that’s not just the case in cosmology.
