The Day Sussex Died

Posted in History with tags , , , on June 30, 2016 by telescoper

In advance of tomorrow’s sombre commemorations of the centenary of the start of the Battle of the Somme, I thought I’d write a short preliminary piece about a related centenary to be marked today, 30th June 2016.

On this day in 1916 there took place the Battle of the Boar’s Head, the name given to a German salient near Richebourg-l’Avoué in the Pas de Calais region. This battle is remembered locally here in Brighton as The Day Sussex Died. The following brief account is based on the wikipedia article.

The attack on the Boar’s Head was launched on 30 June 1916, as an attempt to divert German attention from the Battle of the Somme which was to begin on the following day, 1 July. The attack was conducted by the 11th, 12th and 13th (Southdowns) Battalions of the Royal Sussex Regiment, part of the 116th Southdowns Brigade of the 39th Division.

A preliminary bombardment and wire-cutting by the artillery commenced on the afternoon of 29 June and was reported to be very effective. The final bombardment commenced shortly before 3:00 a.m. and the 12th and 13th battalions went over the top (most for the first time) shortly afterwards, the 11th Battalion providing carrying parties. The guns lifted their fire off the German front trench and put down an intense barrage in support. The infantry reached the German trenches, bombing and bayoneting their way into the German front line trench and held it for about four hours.

The second trench was captured and held for only half an hour, during which several counter-attacks were repulsed and then the raiders withdrew, because of a shortage of ammunition and mounting casualties. The German support position was not reached by the infantry, because the German defensive tactics included shelling trenches where the British had gained a foothold.

In fewer than five hours the three Southdowns Battalions of the Royal Sussex lost 17 officers and 349 men killed, including 12 sets of brothers, three from one family. A further 1,000 men were wounded or taken prisoner.

The corps commander looked upon the attack as a raid and considered it to be successful.

Here is a photograph of A Company of the 13th Battalion of the Royal Sussex Regiment, taken shortly before the battle; by its end, over 80% of these men were dead.


The losses at the Boar’s Head were shortly to be dwarfed by the horrendous scale of the slaughter on the Somme, but their impact  on families and indeed whole villages in rural Sussex was devastating.  Those who lost their lives in armed conflict should never been forgotten, nor should their sacrifices be appropriated for political ends.

Lest we forget.


The Habitability of the Universe

Posted in Politics, The Universe and Stuff on June 30, 2016 by telescoper

It’s important not to get carried away by the post-referendum doom and gloom. Abraham Loeb’s recent paper on the arXiv suggests the Universe will only be habitable for the next 10,000,000,000,000 years or so. This means that the current state of political chaos  won’t last for ever, though I wonder the paper doesn’t make it clear if Article 50 will have been triggered by the time the last star goes out.

Is life most likely to emerge at the present cosmic time near a star like the Sun? We consider the habitability of the Universe throughout cosmic history, and conservatively restrict our attention to the context of “life as we know it” and the standard cosmological model, LCDM. The habitable cosmic epoch started shortly after the first stars formed, about 30 Myr after the Big Bang, and will end about 10 Tyr from now, when all stars will die. We review the formation history of habitable planets and find that unless habitability around low mass stars is suppressed, life is most likely to exist near 0.1 solar mass stars ten trillion years from now. Spectroscopic searches for biosignatures in the atmospheres of transiting Earth-mass planets around low mass stars will determine whether present-day life is indeed premature or typical from a cosmic perspective.

The BrExit Threat to British Science

Posted in Politics, Science Politics with tags , , on June 29, 2016 by telescoper

After a couple of days away dealing with some personal business I’ve now time to make a few comments about the ongoing repercussions following last week’s referendum vote to Leave the European Union.

First of all on the general situation. Legally speaking the referendum decision by itself changes nothing at all. Referendums have no constitutional status in the United Kingdom and are not legally binding. The Prime Minister David Cameron has declined to activate (the now famous) Article 50 of the Lisbon Treaty which would initiate a two-year negotiated withdrawal, preferring to leave this to whomever succeeds him following his resignation. None of the likely contenders for the unenviable position of next Prime Minister seems keen to pull the trigger very quickly either. The United Kingdom therefore remains a member of the European Union and there is no clear picture of when that might change.

The rest of the European Union obviously wants the UK to leave as soon as possible, not just because we’ve indicated that we want to, but because  we have always been never been very committed or reliable partners. In the words of Jean-Claude Juncker: ‘It is not an amicable divorce, but it was not an intimate love affair anyway.’

I don’t blame the 27 remaining members for wanting us to get on with getting out, because uncertainty is bad for business. Two years is more than enough time for big European businesses to write British producers out of their supply chains and for international companies now based in the United Kingdom to relocate to continental Europe. The current gridlock at Westminster merely defers this inevitable exodus. In the meantime inward investment is falling as companies defer decisions on future plans, casting a planningblight over the UK economy.

My own view, however, is that the longer the UK waits before invoking Article 50 the greater the probability that it will never be invoked at all.  This is because the next PM – probably Boris Johnson – surely knows that he will simply not be able to deliver on any of the promises he has made.

For example, there will be no access to the single market post-BrExit without free movement of people. There won’t be £350 million per week extra for the NHS either, because our GDP is falling and we never sent £350 million anyway.  All the possible deals will be so obviously far worse than the status quo that I don’t think Parliament will ever pass legislation to accept a situation is so clearly against the national interest. I may be wrong, of course, but I think the likeliest scenario is that the referendum decision is kicked into the long grass for at least the duration of the current Parliament.

That doesn’t solve the issue of BrExit blight, however. Which brings me to British science in a possible post-BrExit era. It’s all very uncertain, of course, but it seems to me that as things stand, any deal that involves free movement within Europe would be unacceptable to the powerful  UK anti-immigration lobby. This rules out a “Norway” type deal, among others, and almost certainly means there will be no access to any science EU funding schemes post 2020. Free movement is essential to the way most of these schemes operate anyway.

It has been guaranteed that funding commitments will be honoured until the end of Horizon 2020, but that assumes that holders of such grants don’t leave the UK taking the grants with them. I know of four cases of this happening already. They won’t come back even if we’re still in the European Union then.

Another probable outcomes are that:

  1. the shrinking economy will cause the UK government to abandon its ring-fence on science funding, which will  lead to cuts in domestic provision also;
  2. a steep decline in EU students (and associated income) will halt the expansion of UK science departments, and may cause some to shrink or even close;
  3. non-UK EU scientists working in the UK decide to leave anyway because the atmosphere of this country has already been poisoned by xenophobic rhetoric.

British science may “endure” after BrExit but it definitely won’t prosper. What is the least bad solution, if we cannot remain?

Keep Calm and Carry On

Posted in Uncategorized on June 25, 2016 by telescoper

I’m still depressed and worried by the referendum vote, but it isn’t the British way to yield to despair. Let’s take the advice of a previous generation…


It seems clear that we are set to remain in the EU for the forseeable future, as the Leave campaigners are in no hurry to invoke Article 50 of the Lisbon treaty. I think there’s a real chance that we’ll end up staying in the EU after all.

In any case we are still in the European Union now. So. Chin up everyone. Business as usual!

P.S. Another Exit

Posted in Biographical, The Universe and Stuff on June 24, 2016 by telescoper

The news about yesterday’s vote to take the United Kingdom out of the European Union reminded me that I haven’t yet mentioned on this blog that I’ll shortly be making an exit of my own although it is completely unconnected with and far less important than the EU referendum! Hopefully this will answer a comment on a poem I recently posted

I will be stepping down as Head of the School of Mathematical and Physical Sciences (MPS) and leaving the University of Sussex at the end of July. I made this decision some time ago and it was annnounced publicly by the University of Sussex in May, but at that time I was busy marking examinations and doing other stuff and I never got around to mentioning it on here.

I do not propose to go into detail about the reasons for my resignation, which are a mixture of personal and professional. Suffice to say I have found the many burdens and frustrations of my current job just too onerous to manage and therefore concluded that it’s better for all concerned if I leave and make way for someone better suited to the position.

I will be taking a short career break for health reasons, and returning to the  School of Physics and Astronomy at Cardiff University, to continue my research in astrophysics and cosmology in connection with the new Data Innovation Research Institute.

My appointment in 2013 was for a 5-year term, so I am leaving after three and a half years. MPS is in a very good position, with record student numbers and research income. I would not have decided to leave if I thought my departure would in any way jeopardise the progress that has been made over the last few years or the plans already in place for the next few years.

I’d like to take this opportunity to thank everyone I’ve worked with at Sussex for being such great colleagues and wish them all the very best for the future.


Britain votes to leave the EU

Posted in Politics on June 24, 2016 by telescoper

My once and future home….


Today is a sad day for Britain and for Wales. The UK has voted to leave the EU.

Here in Wales we have overwhelmingly benefited from EU membership. Between 2007 and 2013 alone we received over £1.8billion in structural funding from the EU. Our universities prosper through EU co-operation and funding, a brand new campus in Swansea has just been completed – thanks to EU funding.

Those who have fought for remain, from across the political spectrum, have fought with love and wisdom. They have put aside party politics to fight for a greater, a stronger, a better UK – a better Wales. Thank you to everyone who got out and campaigned, who leafleted, who talked to friends about the benefits of the EU. Thank you.

Today we look back on what we have lost. Tomorrow we get together to help our broken and bruised country get back on its feet. This is a time to come together.

Dear Brexiteer. What we need you to do now.

Posted in Politics on June 24, 2016 by telescoper

I’m too desolated by the referendum result – and too busy – to comment for now, but here’s a post that encapsulates a lot of what I feel.

I continue to hope that we will remain in the EU. There may be another referendum next year. I think that’s always been Boris’ plan.

But in the meantime, Cameron has resigned and we’ll get a new right-wing government with new policies without a General Election having taken place. It’s a coup.

Those of you who voted BrExit because of the alleged democratic failings of the EU should ponder on that.


So well done, first of all. You listened to the arguments, the same ones I listened to. You heard all the same information I did, you listened to the same debates that I did, but you voted to leave. And you won. I take that – it was a democratic process and sometimes in the democratic process you lose, as I have done.

The referendum has activated the political energies of people who haven’t been interested in politics for some time, so we are told, and many of them are like you, who voted to leave. So here’s the plea of the losing side to you now.

Firstly, don’t stop – don’t stop with your political passion and activism, because we need you now. We need you to be active, we need you to keep talking to the people who you trusted with this vote, and we need you to…

Referendum Day

Posted in Biographical, Politics on June 23, 2016 by telescoper

Today has been a very eventful day. First I was up at 6am to get to my local polling station in order to cast my vote in the EU Referendum  as soon as the doors opened. I then had to get up to campus and spent all day from 9am until now interviewing for a Lectureship in Probability and Statistics. In between there have been thunderstorms, torrential rain, and flooding. Also, after checking the bookies’ odds on the Referendum result, I decided to place an insurance bet on Leave of £100 at 10/1 against. Given the closeness of the opinion polls I think those odds are far too long.

I’m far too tired to stay up and follow the results coming in, but tomorrow morning I’ll wake up to find that the UK will remain in the European Union or that I’m £1000 richer.

Anyway, for those of you out there who still haven’t voted – perhaps because of the inclement weather – there’s still three hours to get to it!


Why I will be voting “remain” in tomorrow’s referendum

Posted in Uncategorized on June 22, 2016 by telescoper

Abother personal take on the EU Referendum, from Rhodri Evans..


Tomorrow (Thursday 23 June) the (Dis)united Kingdom is holding a referendum to decide whether its four constituent countries should stay as members of the European Union or not. The fact that I refer to the “United” Kingdom as the “Disunited” Kingdom may suggest that I want out of the European Union. But, I don’t.

I think Wales benefits hugely from being a member of the European Union (EU). At the moment, Wales cannot make the decision about our membership on our own, it is decided at a (D)UK level, which means England, Scotland, Northern Ireland and Wales all pooled together. So, it may be the case that Wales (and Scotland) decide they want to stay in the EU, but the overall DUK vote is “out” because most of the DUK’s population is based in England.

I am not sure what the reaction to such a scenario would be in Wales…
