Walter Greiner 1935 - 2016

I don't think I posted anything here last year noting the death of Walter Greiner.  He was a major figure in nuclear physics in all the time I've been doing it, and someone closely related to people I have had close links with research-wise, though I only actually bumped into him a couple of times that I remember.  

Anyway, I notice that the European Physical Society posted an obituary of him earlier this month, so rather than attempt to write a potted biography of someone I knew mostly through second-hand observations,  I direct interested readers to the EPS obituary.

Machiavellian spot-the-difference

This is somewhat off-topic, but I wonder if readers have ever noticed the similarity in appearance between Florentine politico Machiavelli, whose most famous work advocated acting immorally if it achieves the desired political ends, and contemporary politician Jeremy Hunt, who has governmental responsibility for looking after the NHS?

Euroschool on Exotic Beams

I notice that the latest in the series of Euroschools on Exotic Beams is open for registration.  It is a summer school intended for PhD students and young researchers working on nuclear physics involving radioactive ion beams.  If you are such a person reading this, then follow the link above to have a look and consider applying to attend.  There are a great range of lecturers covering experimental and theoretical aspects, and spending a few days in Normandy in late summer can't be the worst thing to do.  

The Euroschool series has a great history of publishing the lecture notes and making them freely available.  If you follow the link above you can easily find them.  They are a great resource for graduate level nuclear physics study, covering a very broad range of topics.  It also includes one instance of my friend and colleague Wilton Catford citing a certain R. A. Zimmerman.

Ludvig Faddeev (1934 – 2017)

I saw from a friend's Facebook post that Ludvig Faddeev, known to me for his eponymous equations, died a couple of days ago.

Faddeev was a mathematician and physicist whose work is of great importance in few-body nuclear physics.  In particular, he developed a method for solving the quantum three-body problem that can be used when studying, e.g the triton or 3He, but also weakly-bound nuclei in which there is 2-neutron halo along with a strongly-bound core, such as 11Li. 

At this point I have to confess that I have never tried solving the Faddeev equation myself, though this blog post is tempting me to do so.  If someone reading would like to write a quick primer, then I'd be more than happy to post it here.

Bright Club #12

A series of reminder emails are doing their job in reminding me that I am going to be one of the participants in Bright Club #12, which is happening quite soon, on March 9th in the Boilerroom in Guildford.  Bright Club, for the uninitiated is a stand-up comedy event where the performers work in academia.  The name is a bit show-offy for my liking.  Like joining Mensa or something.  But it's an okay pun on Fight Club, so okay.  Anyway, if you want to come and see me, and my absent sense of embarrassment standing up and attempting to be funny, along with some other more competent people, then tickets are available here.

I might start a rival event called Shite Club.

Fusion 17

I'm at the FUSION17 conference in Hobart, Tasmania.  At the beginning of today's session I tweeted, using the hashtag #fusion17 not realising that it had already been used by a party being organised in Texas this spring break (see attached picture).  Oh well.

The conference is one of a series which has been going for 20 years to bring together people working on nuclear reaction mechanisms which lead to fusion.  That's a somewhat minor part of what I do, though what I do doesn't really fall within any one specialist conference series, so it's about as on-topic as most conferences I ever go to.  The fact that I know quite a few of the people here is probably a sign that I belong sufficiently well enough to attend.  

We're about half way through day one, and as usual, the conference talks have filled me with enthusiasm for the research area, and given me lots of ideas of calculations to perform.  I was also pleased and somewhat embarrassed to see my name in the talk by Michael Thoennessen in which he listed the names of all attendees at the conference who were co-authors on papers which announced the discovery of new isotopes.  I have 4 written next to my name, apparently being a co-discoverer of four isotopes.  I can't claim to have been on the experiment(s) leading to these discoveries, but I was involved enough in some of the calculations associated with them to be on the discovery papers.

Erasmus Joint Master Degree in Nuclear Physics

If any readers are looking for opportunities to study for a funded master's degree in nuclear physics, an email I received earlier this week might just have what you are after.  It's a 2-year taught master's degree course entitled (deep breath) Erasmus Mundus Joint Master Degree in Nuclear Physics (EMJMDNP).  The email says that "the course is supported by EACEA Agency of European Union with full scholarships (including travel costs and health insurance)"

The degree is co-taught across several universities across Europe, and from what I can see all students will spend some time in each of Spain, France, and Italy.  It looks pretty interesting, and well worth considering as a next step if you have just finished your bachelor's degree and nuclear physics takes your fancy.  Tell them I sent you :-)

UK Leaving Euratom. What does it mean?

According to official explanatory notes accompanying the European Union (Notification of Withdrawal) Bill, the withdrawal of the UK from the EU will mean withdrawal from the Euratom programme.  

As an academic nuclear physicist, my knowledge of Euratom comes from its role within the European research mechanism.  The Euratom page at the European Commission website says that "Euratom is a complementary research programme for nuclear research and training" and goes on to describe its role in research into decarbonisation, nuclear fission research, nuclear waste management, fusion energy, and radiation protection.  Its most high–profile project is the ITER fusion reaction; the International Thermonuclear Experimental Reactor, based in France, to which Euratom contributes, with other partners.

But as well as being a scientific research programme, Euratom is also a very high-level treaty that the UK has just confirmed it will leave at the same time as it leaves the EU.  What I have not seen anything about is whether and how the UK will step in to replace the funding of research in these areas.  Will we re-join ITER as an independent partner?  What about pursuing the other goals of the Euratom research project for UK scientists?  Will they have increased funding via the UK Research Councils to replace Euratom?  The UK Government need to state the position on the wider consequences of departure from Euratom, if they wish to inspire confidence to the UK scientific community in the management of the Brexit process.

Buy Lego. Save the world.

A friend of mine who works at Surrey Satellite Technologies Limited alerted me to this pretty neat thing:  Lego has a scheme whereby proposed kits and designs can be produced by them if they receive enough support on a community website.  Someone has proposed a kit for the Galileo Global Navigation Satellites, parts of which are made here in Guildford.  If you'd like to see the kit made available, please add your support at the Lego Galileo Spacecraft page.  It doesn't oblige you to buy one when it gets to market, but Lego is pretty cool stuff, and Lego are also a place where at least I feel comfortable spending my money, given that every time we spend money we are undertaking an act about as political as anything else we do.

Applications of Nuclear Physics

A really nice and extensive article on many of the uses of nuclear physics appeared on the arXiv this week, written by Anna Hayes of Los Alamos Lab.  As well as including the most obvious applications (weapons and power) and perhaps the most widespread, as well as the first, application (medical), it also covers some of the neat uses in areas like geology, where the study of isotopic abundances in things such as groundwater can tell you what it going on far underground.  I've yet to read the whole thing yet, but it looks definitely worth bookmarking as a go-to piece whenever you are looking to discuss the range of things nuclear physics is applied to.

The figure attached to this post is from the paper, showing some of the ancient (pre-historic) natural nuclear fission reactors that existed in what is now Gabon, detected by the unusual isotope ratio of the remaining uranium, as well as some fission products.  See Anna's paper for more details!
