Tonight on Newsnight Scotland, they claim they're close to pinning down | :00:21. | :00:23. | |
the elemental particle which has eluded science for a generation. We | :00:23. | :00:26. | |
look at the Scottish academic contribution and ponder the | :00:26. | :00:28. | |
significance of Higgs Bosun for the rest of us. | :00:28. | :00:31. | |
Good evening. Science is closing in on the most elusive thing in the | :00:31. | :00:34. | |
universe. A symposium that's just begun in Paris is to be told the | :00:34. | :00:37. | |
latest developments in the hunt for the Higgs Boson, the theoretical | :00:37. | :00:40. | |
particle that gives everything else its mass. The theory behind the | :00:40. | :00:43. | |
Higgs came out of Edinburgh university in the 1960s. Now dozens | :00:43. | :00:46. | |
of scientists from Scotland are among those looking for it at the | :00:46. | :00:48. | |
European nuclear research centre CERN. One of them has told this | :00:48. | :00:51. | |
programme that the breakthrough is just months away. From Switzerland, | :00:51. | :01:01. | |
:01:01. | :01:04. | ||
here's our science correspondent This is Mission Control for a time | :01:04. | :01:09. | |
machine. Science is turning the clock back 13.7 billion years to a | :01:09. | :01:16. | |
point less than a billionth of a second from the Big Bang. To do | :01:16. | :01:21. | |
that, CERN has built the world's biggest machine beneath the border | :01:21. | :01:25. | |
between France and Switzerland, the large Hadron Collider. This is the | :01:25. | :01:28. | |
capital of superlatives, the coldest place in the universe is | :01:28. | :01:34. | |
here. The hottest place in our galaxy is here, so is theentiest | :01:34. | :01:39. | |
space - a single proton going around the large Hadron Collider, | :01:39. | :01:43. | |
all 27 kilometres of it. It can go around there 11,000 times every | :01:43. | :01:49. | |
second. Dozens of physicists from Glasgow | :01:49. | :01:53. | |
and Edinburgh Universities are working here alongside colleagues | :01:53. | :01:57. | |
from across Europe. The large Hadron Collider is the world's | :01:57. | :02:04. | |
highest energy colliding machine. It accelerates protons up to 7 | :02:04. | :02:07. | |
trillion electron votes. That is then converted into new matter we | :02:07. | :02:13. | |
hope, and what we aim to do is to discover new particles. | :02:13. | :02:17. | |
Among them, potentially the most significant particle of them all. | :02:17. | :02:24. | |
Whether or not an apple was ever really involved, Isaac Newton was | :02:24. | :02:30. | |
sure it was a gravitational force, but what newtonian physics and | :02:30. | :02:33. | |
indeed Einstein couldn't show is why even if you take this apple | :02:33. | :02:38. | |
into the weightlessness of space, it will still have mass. What gives | :02:38. | :02:42. | |
it mass? The prevailing theory is a fundamental particle gives that | :02:42. | :02:48. | |
property of mass to everything else in the universe. The Higgs Bosun | :02:48. | :02:52. | |
was first postulated in Scotland along the with the man who came up | :02:52. | :02:57. | |
to it in the '60s - has had a little trouble explaining it in | :02:57. | :03:03. | |
layman's terms. It's - eh, it's - it's - I mean, it's the relation | :03:03. | :03:09. | |
between waves and particles, electromagnetic waves, photoons - | :03:09. | :03:19. | |
:03:19. | :03:19. | ||
waves in this quantity, which oscillates up and down that trough | :03:19. | :03:24. | |
have a quanto which are called the Higgs Bosun. That probably tells | :03:24. | :03:27. | |
you nothing. Finding the Higgs Bosun has been | :03:27. | :03:31. | |
even more difficult. Only the large Hadron Collider has the power to | :03:31. | :03:34. | |
bring it within reach. It accelerates a stream of particles | :03:34. | :03:39. | |
to almost the speed of light and does the same to a second stream | :03:39. | :03:42. | |
travelling in the opposite direction. Then the two streams are | :03:42. | :03:47. | |
smashed head on inside one of four huge underground detectors. The | :03:48. | :03:52. | |
hottest place in our galaxy is a hundred metres below my feet. It's | :03:52. | :03:57. | |
the centre of the At his detector, just one of the experiments ranged | :03:57. | :04:01. | |
around the large Hadron Collider. If you think about it as a camera | :04:01. | :04:06. | |
that takes 40 million pictures every second, then you've got Atlas | :04:06. | :04:10. | |
just about right. That's what it looks like, except in real life | :04:10. | :04:15. | |
it's even bigger - this big. It took 15 years to build, and some of | :04:15. | :04:18. | |
the most sensitive components were made in Scotland. To underline the | :04:18. | :04:22. | |
scale of the enterprise, the Atlas control room is in Switzerland, the | :04:22. | :04:27. | |
central control is in France, but how close has this brought us to | :04:27. | :04:34. | |
the Higgs? Imagine a house with many rooms. A house with exactly | :04:34. | :04:41. | |
signature rooms, OK? We have - and what we do is we open the doors of | :04:41. | :04:47. | |
each room and say, the Higgs is not here. It is not here. It is not | :04:47. | :04:52. | |
here, and today we are left with one room, and we should - this room | :04:52. | :04:59. | |
- we should be able to open the door and decide if the Higgs exist | :04:59. | :05:03. | |
or doesn't exist by the next few months. | :05:03. | :05:07. | |
None of this would have been possible without vast quantities of | :05:07. | :05:11. | |
computing power. That power is used to analyse the results of real | :05:11. | :05:17. | |
collisions and to simulate what Higgs event might look like. | :05:17. | :05:20. | |
simulate currently about two billion events, and each event | :05:20. | :05:25. | |
takes about 20 minutes to simulate, so this is - it would take you | :05:25. | :05:28. | |
maybe 75,000 years on one computer to try and do this. Instead of | :05:28. | :05:33. | |
doing that we have hundreds of thousands of CPUs across the grid, | :05:33. | :05:38. | |
and then we run these simulations all in parallel. It takes a massive | :05:38. | :05:42. | |
infrastructure to try to do that, and some of that infrastructure is | :05:42. | :05:46. | |
located here at CERN. There's many sites that are located all across | :05:46. | :05:50. | |
the world. In particular, there's some Scottish sites as well. Ph.D | :05:50. | :05:53. | |
students from Edinburgh and Glasgow Universities are among the | :05:53. | :05:57. | |
thousands working here. It's not just high-energy physics. It's high | :05:57. | :06:02. | |
pressure too. There is a lot of, like, pressure around and a lot of | :06:02. | :06:06. | |
requirements, and we are really trying to work hard and to get the | :06:06. | :06:10. | |
results as soon as possible. currently a fourth-year Ph.D | :06:10. | :06:15. | |
student, so I feel a lot of pressure. I have to submit in a few | :06:15. | :06:21. | |
months' time, so I am writing my these's, trying to finish the | :06:21. | :06:25. | |
analysis, because when everything is exciting, I don't want to be | :06:25. | :06:31. | |
writing. I want to be on the front line of it. None of this is cheap, | :06:31. | :06:36. | |
although arguably, CERN has already paid for itself by inventing the | :06:36. | :06:41. | |
web. We want to do these particle | :06:41. | :06:44. | |
physics experiments and look at all of these particles coming off you | :06:44. | :06:48. | |
might say, where does that fit in with the rest of the world? It's | :06:48. | :06:53. | |
very abstract, but in fact, these are now being applied to medical | :06:53. | :06:57. | |
science and could replace X-rays or PET scanners, and these could | :06:57. | :07:02. | |
reduce the doses you give to people when you want to diagnose illnesses. | :07:02. | :07:06. | |
For now, though, most attention is on finding the Higgs Bosun. What if | :07:06. | :07:10. | |
they throw open the door of that last room, and it's not there? | :07:10. | :07:14. | |
it's not there, that would be even more interesting for us. Of course, | :07:14. | :07:18. | |
that's the whole point that we've gone on this great trail of | :07:18. | :07:23. | |
discovery, and then what we were hoping to find was the Higgs | :07:23. | :07:29. | |
particle. It's the simplest - it's Occam's Razor. It's the simplest of | :07:29. | :07:35. | |
all things that we see is through the Higgs Particle. If it doesn't | :07:35. | :07:40. | |
appear in the way we think it will appear, then that'll really get the | :07:40. | :07:43. | |
community as a whole really scratching their heads because | :07:43. | :07:46. | |
essentially all of our theoretical understanding which started with | :07:46. | :07:52. | |
Peter Higgs in the '60s in Edinburgh, that's now going to have | :07:52. | :07:56. | |
to move on in some new direction, which, to be honest, we don't know | :07:56. | :08:02. | |
what direction that would be. has been running for more than half | :08:02. | :08:07. | |
a century. Here sophisticated pieces of equipment that once won | :08:07. | :08:10. | |
Nobel prizes are now garden ornaments. One day the large Hadron | :08:10. | :08:16. | |
Collider will also be history. Until then, questions like, how | :08:16. | :08:20. | |
many dimensions are there? Will be enough to be getting on with. | :08:20. | :08:23. | |
I'm joined now by Glasgow university physics professor Tony | :08:23. | :08:26. | |
Doyle, who's been working on the Hadron project, as you saw in the | :08:26. | :08:28. | |
film there. And in Edinburgh is Heriot Watt University vice | :08:28. | :08:31. | |
principal Professor Julian Jones, whose work has been more in the | :08:31. | :08:39. | |
field of applied physics. Just on that film, Tony Doyle, 59 | :08:39. | :08:45. | |
rooms - you're in room 60. We're in room 60, which is quite exciting, | :08:45. | :08:48. | |
right? You've gone through all the possibilities up to this point. | :08:48. | :08:52. | |
We're left with a small window. It's not even a door. It's now a | :08:53. | :08:57. | |
small window that we're opening. It may or may not... Are you still an | :08:57. | :09:01. | |
optimist this thing exists? I am an optimist that in the next year | :09:01. | :09:04. | |
we'll certainly determine whether or not the Higgs Bosun exists in | :09:04. | :09:08. | |
the way that is predicted. Before we broaden this - just explain to | :09:08. | :09:13. | |
me, what this would show - it would give us an explanation within | :09:13. | :09:17. | |
standard physics as we know it of why particles have mass. That's | :09:17. | :09:22. | |
basically it. That's right, so how - so the way we understand forces | :09:22. | :09:26. | |
and matter and how they interact is through these particles. What we | :09:26. | :09:29. | |
don't understand is why these particles have mass, and | :09:29. | :09:33. | |
fundamentally, the Higgs Bosun gives mass to all of those other | :09:33. | :09:38. | |
particles. But what it doesn't do is give us the grand unified theory, | :09:38. | :09:43. | |
does it, which is to unite quantum theory with relativity. That would | :09:43. | :09:47. | |
still need a theory of gravity, which it wouldn't give us. | :09:47. | :09:51. | |
Absolutely. That's beyond us, and in fact, we don't have experiments | :09:51. | :09:55. | |
- even though the scale of the large Hadron Collider is certainly | :09:55. | :10:01. | |
very large, right? It's this 27- kilometre... Bigger? We'll need | :10:01. | :10:04. | |
something that can go back to beyond a billionth of a second | :10:05. | :10:11. | |
after the Big Bang, right, so way, way back to something called the | :10:11. | :10:15. | |
Plank Scale. That's not going to challenge us for many, many years | :10:15. | :10:20. | |
to come. Julian Jones, I am just wondering - the excitement | :10:21. | :10:24. | |
generated by this - do you have a - you're trying to get young people | :10:25. | :10:29. | |
in Scotland interested in science. It must be possible surely too use | :10:29. | :10:33. | |
this as almost a magnet - is probably the wrong phrase to use, | :10:33. | :10:38. | |
given what we have just been talking about. Absolutely, and we | :10:38. | :10:42. | |
already see it - demand for undergraduate courses in the basic | :10:42. | :10:46. | |
sciences and physics has certainly grown in recent years. It's a very | :10:46. | :10:51. | |
good thing too. When you say it's grown, has it grown because more | :10:51. | :10:55. | |
young people are going through higher education, or has the demand | :10:55. | :10:58. | |
for science subjects grown relative to the demand for humanity | :10:58. | :11:01. | |
subjects? Yes, it's grown in relative terms. I think there are | :11:01. | :11:05. | |
two reasons for that. Part of that is because of the philosophical | :11:05. | :11:10. | |
appeal of things like the kind of work that Tony and his colleagues | :11:10. | :11:16. | |
do. It's partly too I think because of a realisation that that kind of | :11:16. | :11:19. | |
education contributes to a modern technological economy, and there is | :11:19. | :11:23. | |
a good chance of getting a worth while job out of it. Is it a | :11:23. | :11:28. | |
broader thing than just, I can get a job? Heavens, yes. I think it's a | :11:28. | :11:34. | |
job which contributes, and surely almost everybody watching this | :11:34. | :11:37. | |
programme will feel that it would be worthwhile to rebalance the | :11:37. | :11:40. | |
economy by good, high-value manufacturing, and I think that's | :11:41. | :11:45. | |
inspiring too. There has been a culture of change, hasn't there? 30 | :11:45. | :11:51. | |
years ago, science had a bit of a bad image. It was Dr Strangelove, | :11:51. | :11:56. | |
guys that make nasty things like chemical warfare, whereas now | :11:56. | :11:59. | |
people look at this and think, my gosh, that's exciting. Computing | :11:59. | :12:04. | |
and all the rest of it people think is really cool. There has been a | :12:04. | :12:09. | |
whole change of image. For me, the inspiration was the Apollo | :12:09. | :12:13. | |
programme. For people my age, that was what inspired us. Now I think | :12:13. | :12:17. | |
we have moved on. Particle physics really has captured the imagination | :12:17. | :12:23. | |
of the public as a whole. That's the first step in terms of | :12:23. | :12:27. | |
inspiring the next generation of physicists, so that's what we're | :12:27. | :12:31. | |
doing next. That's what Julian was saying. Actually, there are now | :12:31. | :12:35. | |
more people interested in science, technology, engineering and | :12:35. | :12:38. | |
mathematics. Do you think we should be doing more to get a sort of | :12:38. | :12:42. | |
public understanding of science, say, in - amongst your people, | :12:42. | :12:46. | |
perhaps, in schools? I know this stuff is very, very complicated. | :12:46. | :12:50. | |
Absolutely. But the way you explain it, you can start to see why it's | :12:50. | :12:55. | |
so exciting. There is a much clearer understanding now amongst | :12:55. | :12:57. | |
those who practising science that there's a responsibility to explain | :12:58. | :13:03. | |
our work to a wider work to an audience, and I'm sure Tony's | :13:03. | :13:08. | |
university is exactly the same as mine. We spend a good deal of time | :13:08. | :13:11. | |
nowadays going out into schools and working through our learned | :13:11. | :13:13. | |
societies just to try to communicate better than we have | :13:13. | :13:17. | |
done before, and we're seeing the benefits of it as well. I am | :13:17. | :13:20. | |
curious, Tony Doyle - you know, if people watch this and say, what's | :13:20. | :13:25. | |
this got to do with the price of fish? What does it have to do with | :13:25. | :13:32. | |
the price of fish? Famously, non- stick plans, lasers, quantum | :13:32. | :13:36. | |
mechanics, and particle physics - what? The world-wide web, of course, | :13:36. | :13:40. | |
which we needed in the '90s, so when I was a younger scientist then, | :13:41. | :13:45. | |
I needed to communicate with... order to get this massive - and as | :13:45. | :13:48. | |
we explained in the film there, it's almost like parallel | :13:48. | :13:52. | |
programming is involved in this going... Yes. They invented the | :13:52. | :13:55. | |
world-wide web. That's what we did in the '90s. The next step was the | :13:56. | :13:59. | |
grid. So it's not the particles themselves that necessarily have | :13:59. | :14:02. | |
the implications. It's the development of the instruments that | :14:03. | :14:07. | |
allow you to eventually say, gosh, we think we have found it. That's | :14:07. | :14:10. | |
right. We have to leave it there. Thank you very much indeed. | :14:10. | :14:20. | |
:14:20. | :14:33. | ||
A very quick look at tomorrow's That's all we have time for tonight. | :14:34. | :14:43. | |
:14:44. | :14:47. | ||
I'll be back again tomorrow. Until Hello. Lots of cloud and mist | :14:47. | :14:50. | |
around overnight. One or two fog patches too. It all adds up to a | :14:51. | :14:54. | |
pretty grey start on Wednesday. Like obtuse, some places will | :14:54. | :14:57. | |
brighten up with a little bit of sunshine, but for many, it will | :14:57. | :15:03. | |
stay rather glum, particularly in these western areas, to the west of | :15:03. | :15:09. | |
the Pennines across the West Indies, expect fairly cloudy day. In the | :15:09. | :15:14. | |
east, we could get sunshine. Where we get the sunshine, 12-13 Celsius. | :15:14. | :15:17. | |
We could see 12-13 Celsius in the west, but outbreaks of rain are | :15:17. | :15:20. | |
working across Devon and Cornwall. That same area of rain will push | :15:20. | :15:24. | |
into the west of Wales during the afternoon. Further north across | :15:24. | :15:27. | |
Northern Ireland, some brightness is possible early on, but overall, | :15:27. | :15:31. | |
a cloudy afternoon, a little bit of drizzly rain here at times too to | :15:31. | :15:36. | |
end the day. For most of Scotland, it should be dry. Lots of cloud | :15:36. | :15:39. | |
across central and Southern Scotland. In the north, we may well | :15:39. | :15:43. | |
get some sunshine, though again, we might get stubborn fog patches. | :15:43. | :15:47. | |
Thursday night, areas of rain working northwards. Rain may return | :15:47. | :15:50. | |
to parts of Northern Ireland and Scotland late on Thursday. For | :15:50. | :15:53. | |
England and Wales, Thursday promises some bright or sunny | :15:53. | :15:58. | |
spells. Again, where the sun comes out, temperatures into the teens. | :15:58. | :16:02. | |
It will start cloudy across Eastern England Thursday. It may take a | :16:02. | :16:06. |
