How they 'split the atom' - Brian Trench
Good afternoon, my name is Brian Trench and I'm delighted to welcome you here on behalf
of the Celsius group here at DCU about which I'll say a word in a moment. A very particular
welcome if you don't mind me just drawing attention to it straight away to the members
of the Walton family who are here. Philip, the son of ETSW, his wife Anne and their son
Ian. Philip has assured me that they're keeping physics in the family going and his daughter
is a physicist just as he, his brother and his sister have been physicists as well. As
the title of this event indicates, we're recalling something that happened 80 years ago tomorrow.
In fact there was some doubt as to whether it really happened on the 13th or the 14th
but I'm sure Brian will put us absolutely right on that. Brian Cathcart. And we're doing
so in the context of Dublin City of Science 2012. So we're looking at this not just as
a key moment in 20th century science, which of course it was, but also in terms of its
wider cultural, social resonance. And Brian Cathcart in particular in his book, this wonderful
book The Fly in the Cathedral, and in the talk he will give us now in a moment, looks
at how the news about this discovery was managed, in fact unsuccessfully. An attempt was made
to manage it. I'm setting off some reactions here that I didn't intend. I'll turn it off.
It's possible that Ty is interrupting, is interfering with me because these are actually
high energy events that are going on with Ty. Ty is actually from CERN. I had to mention
that at some stage. What was I saying before that? Yes, indeed that this is a bigger event
than just, that the event of the 14th of April was not just a singular scientific event but
also was a bigger cultural and social resonance. And this is one of just two, I think, is that
right Brian? Surviving pictures that were taken by the media, indeed where the three
gents made themselves available to the media, just long enough for two photographs to be
taken. In the middle Ernest Rutherford, the head of the Cavendish Laboratory. On the left
Ernest Walton and on the right John Cockcroft. And that was on the 2nd of May, taken on the
2nd of May 1932. And on that same day, the Irish Times in an editorial celebrated a triumph
of science. And it remarked that the average man's knowledge of the atom is vague and thanks
to recent fiction of the scientific school, rather terrifying. I think that's a reference
probably to HG Wells which isn't that recent, but there you are. And it talks again about
the plain man knows only that science has been striving in recent years to release and
control the stored vigour of the atom as in earlier ages it pursued the philosopher's
stone and that the splitting, in inverted commas, as we had it also in the title of
this event, of the atom was an essential factor of success. It goes on to talk about the plain
man a bit further and talks about the possibility of the splitting of the atom, with the splitting
of the atom man becomes master of a destructive force, or could become master of a destructive
force that enabled him to hold the world to ransom. This is a reference to the fiction
of a scientific character. While Lord Rutherford's announcement is silent upon such horrific
possibility, it is difficult he states to say to what this discovery may lead. Well
we're in the fortunate position 80 years later of being able to say to what this discovery
has led. And not all of it necessarily entirely welcome. At the end then it says it must be
a cause of pride to all Irishmen that one of the two victors of the atom, Dr ETS Walton
is a young graduate of Dublin University.
The CELTIUS group which is hosting today's event set up about five or six years ago to
support and to undertake research on the cultural, ethical, legal and social issues in science
that gives you CELTIUS. It happened to be the 250th anniversary of the birth of CELTIUS
so he was kind of in our consciousness at the time and we've organised annual symposia
and seminars of various kinds over the years, including hosting the visit of Bruno Latour
very recently to DCU, one of the pioneering figures in social studies of science. And
there are a number of PhD students associated with the group.
In organising this event as I said we are conscious that we are in the year of Dublin
city of science and in doing this we're trying to contribute in some way to the putting into
mainstream culture, and I can't find a more elegant way of saying it, but I can in French
in a moment, putting into mainstream culture science, scientific institutions, scientific
discoveries, scientific developments. Actually it's the French theoretical physicist who
writes also essays on science, Jean-Marc Levy-Leblanc, who refers to la mise en culture de la science,
the placing into culture of science. So that is partly what we are trying to achieve with
organising an event of this kind, as indeed many other events of the city of science year
are also doing.
One measure of the place of science and culture, one small measure, might be the presence of
representations of scientists on stamps. And actually if you were to consider scientists
and scientific issues on Irish stamps you would say that Ireland was a very scientific
culture, indeed. The only person ever to have been featured twice on a commemorative stamp
is a scientist. Apparently you only get one chance at doing it, so I'm afraid, Ernest,
you had your chance and this was on the centenary of his birth in 1903, 2003 the stamp was issued.
William Rowan Hamilton actually appeared twice, but that's largely due to Deborah's great
interest in William Rowan Hamilton. But here's a little one for you, if Ernest Walton has
been commemorated on a stamp of Ireland, what other country do you think might have
commemorated Ernest Walton on a stamp? This is a little bit, actually the Walton family
are excluded from answering this question. This is a little bit about the physics of
philately or the philately of physics. The answer is Saint Vincent and Grenadines. Now
I bet none of you thought of that one. Actually Saint Vincent and Grenadines has actually
issued a series of stamps with Nobel Prize winning scientists on them. Anyway, I hope
we've established the context for this and we're going to hear first of all from Brian
Cathcart, who I had the pleasure of introducing in a quite different context at another conference
just two months ago and meeting at a previous conference just before that earlier in the
year, one about journalism history, the next one about media diversity and today about
the history of nuclear science. He may have time to tell you how he came to be interested
in this, but he'd been writing about it for over 20 years and I think the first article
that I came upon by Brian about Ernest Walton dates back to about 20 years ago and he's
published this wonderfully well-told story, The Fly in the Cathedral, which I recommend
to anybody who might even be bemused by the science of the so-called splitting of the
atom, strongly recommend it to you. It's available in paperback and from most good
bookstores if you try hard enough anyway. Brian is a journalist by background, a journalism
lecturer, a journalism professor now in Kingston University in Surrey and as I say has a long-standing
personal interest that really is outside of his professional activity as a journalism
lecturer and professor in the history of nuclear science. Really his book, I just was
speaking to somebody outside about his book and he said to me, well a science teacher
said to me just recently, this is the best book about science that I know. It really
is popular science of a kind that we need much more of. It tells a really great story,
but in the telling of the story and in the painting of the characters and in the description
of the apparatus, it really does lead us into the core of the scientific discovery
process itself. So a great pleasure in welcoming Brian Cathcart.
