Daily Show Explains the LHC

You can always count on the Daily Show. As John presaged earlier this month, correspondent John Oliver visited CERN to do a report on the LHC, which has finally appeared. Watch as John Ellis lays the science smackdown!

The best thing about it is that, once again, Jon Stewart and company have taken an issue that completely flummoxed most major news media — in this case, the purported danger that the LHC will destroy the world — and actually get it right. In addition to visiting CERN itself, Oliver scored an interview with Walter Wagner (“graduated UC Berkeley with a Minor in Physics”), originator of much of the hysteria and lawsuits. You’ll get to hear Wagner explain that the probability the LHC will destroy the world is — wait for it — fifty percent. You know, because when you have two things that can possibly happen, obviously each has half the probability, right? I don’t want to say too much about Walter Wagner, because, if nothing else, the guy is really fond of a good lawsuit. So I have no comment whatsoever on Walter Wagner’s competence or sanity. But I do know people who are utterly incompetent and completely insane, who resemble Walter Wagner in certain ways. I’ll stop there.

See, major news media? It’s not that hard!

Death by Physics

I’m not supposed to give away too much here. But recall that Hollywood loves science, and occasionally we can help them out with an interesting idea or two. So it’s possible that if you were to watch tonight’s episode of Bones (8 p.m., 7 Central, on Fox), our plucky heroes Booth and Brennan could be investigating a murder that makes clever use of expertise in physics. It’s even possible that the murder technique was dreamed up in part by one of our previous guest-bloggers, which might very well be reflected in the name of the research institute where the dastardly deed takes place.

I’ve probably said more than I should already.

Science and Journalism, Intersecting

We’re happy to welcome The Intersection, featuring the bloggy stylings of Chris Mooney and Sheril Kirshenbaum, to their new home here at Discover Blogs! Anyone who isn’t already following their excellent work is encouraged to go have a look.

It’s great timing, as Sheril and Chris are experts in the intersection of science and journalism (among other intersections), and that’s going to be a hot topic in the days to come. There was something of a dustup a few months ago, set off by dueling Bloggingheads dialogues, first from science bloggers Abbie Smith and Ed Yong, then by journalists George Johnson and John Horgan. Apparently Abbie was questioning the role of journalists in an era where scientists can reach out themselves through blogs, and George responded in a somewhat intemperate fashion. (He later apologized for the tone, although not really the sentiment.) Much back-and-forth ensued — see responses by Brian Switek and Chad Orzel. And just last week, Geoff Brumfiel at Nature wrote a feature exploring the relationship between science journalism and science blogs, with the tagline: “But can the one replace the other?”

Well, no. Science blogging will never replace science journalism, any more than other kinds of blogging will replace other kinds of journalism. (Of course blogging can include just about any kind of writing, including what we usually call “journalism”; I’m thinking here of the specific case of people whose day job is doing science, and who blog in their spare time.) They have very different roles. Journalists are paid to cover stories of wide interest, to get multiple perspectives on new results, and to be as objective as possible in separating the wheat from the chaff. Science bloggers are sometimes going to blog about something newsworthy, but most can’t be bothered trying to cover every interesting story, and years will pass before a typical blogger picks up a phone to interview a source before posting. Instead, they bring a special expertise and inside knowledge to a field that no general-purpose journalist can hope to match.

I’m not sure what the source of controversy really is. It seems perfectly obvious that science blogging should enrich and extend conventional science journalism, not aspire to replace it. (See also sensible takes from Jessica Palmer at bioephemera and Curtis Brainard at the Columbia Journalism Review. [Hey! A blogger and a journalist!]) Movies didn’t replace live theater, airplanes didn’t replace cars, mammals didn’t replace birds. These are things that serve different functions.

The conversation we should be having is how the two forms can work together. How great would it be, for example, if major newspapers regularly linked to relevant blog entries by real experts when a big science story broke? It might actually require some effort to make something like that happen, just because of the way journalism these days works, including the tradition of embargoed results. When the Bullet Cluster results indicating the existence of dark matter were first released, I was lucky enough to be a participant in the original press conference, so I had access to the papers before most people did. Consequently, I was able to write an informed post that could be pointed to by people looking for an expert-level discussion. But ordinarily, such pre-embargo access is only given to professional journalists. If the communities worked a bit more closely together, we might be able to more regularly combine the reportage and explanatory skills of professional journalists with the in-depth perspective of professional scientists.

Meanwhile, newspapers are dying. CNN shut down its science division. The amount of real science journalism is shrinking dramatically, and any scientist who thinks that’s a good thing for the field as a whole is living in crazy land. The old ways of doing business are crumbling, and we have to find new ways to work together.

A Teaching Moment: Angels & Demons

May 15 will be the premiere of Angels & Demons, the Ron Howard movie starring Tom Hanks and Ayelet Zurer, based on the Dan Brown novel. The narrative moves between particle physics at CERN and religious politics at the Vatican — feel free to provide your own characterization of that particular binary opposition.

Angels & Demons at CERN

We have no idea how good the movie is going to be, but it’s sure to garner attention, and it does feature physics prominently. So the Division of Particles and Fields of the American Physical Society figures that we might as well get some mileage out of it. They recently sent around the email below, encouraging physics departments to host “Angels & Demons lecture nights” to capitalize on the interest generated by the movie. Seems like a good idea to me — rather than spending energy finding flaws in the physics as portrayed in the movie (which are sure to be there), let’s grab the opportunity to spread the word about some exciting science that’s being done in the real world. If nothing else, the most common question about the LHC will change from “Will it make a black hole that will destroy the world?” to “Will it make an anti-matter bomb that could destroy the Vatican?”

This May, Sony Pictures will release Angels and Demons, a movie based
on Dan Brown’s best-selling novel that focuses on an apparent plot to
destroy the Vatican using a small amount of antimatter. In the book
and the movie, that antimatter gets stolen from CERN.

Starring Tom Hanks and directed by Ron Howard, parts of the movie were
actually filmed at CERN. It’s not every day that a major motion
picture places particle physics in the spotlight. The US particle
physics community would like to take advantage of this opportunity to
tell the world about the science behind the movie, the Large Hadron
Collider and the excitement of particle physics.

Along these lines, the Fermilab, SLAC and US LHC users organizations
will join forces to organize Angels and Demons public lecture nights
at universities or other venues across the country when the movie
premieres in mid-May. While each institution will be responsible for
the local logistics of planning the public lecture, the Fermilab
Office of Communications and the CERN Press Office can help. A Web
page on the US LHC Web site (http://www.uslhc.us/Angels_Demons) will
provide you with materials that will include:

– a template PowerPoint talk, for your use if helpful

– a template poster to advertise the lecture at your institution

– tips on answering tough questions

– information on how to broadcast the lecture on the Web

If you would like to host a lecture, please contact Elizabeth Clements
(lizzie@fnal.gov) or Katie Yurkewicz (katie@fnal.gov). They will give
you more information and help you with publicity for your event.

While the movie contains a great deal that is not about science,
physics is central to its plot. This makes it possible for US
physicists to lecture on the science behind the movie, the Large
Hadron Collider and particle physics in general. The physics at the
heart of Angels and Demons–the potential destruction of the Vatican
by a small chunk of antimatter–calls attention to what happens when
matter and antimatter meet. This in turn calls attention to the fact
that the absence of practically any antimatter in the universe is
crucial to our existence. To understand that absence is one of the big
challenges of particle physics. Public lectures could discuss the
challenge of the missing antimatter, possible solutions and how
experiments in both the intensity and energy frontiers will explore
these mysteries.

In order to allow enough time to plan and advertise the lecture at
your institution, the time to get started is now. We hope that you
will make the most of this wonderful opportunity to get the public
excited about particle physics and the many anticipated discoveries
that lie ahead.

Sincerely,

Boris Kayser, Chair
Division of Particles and Fields
American Physical Society

Guest Post: David E. Kaplan on the LHC on the History Channel

You may have heard that there’s some sort of big science machine scheduled to turn on in Europe. Very soon, in fact: first (official) beam at the Large Hadron Collider is supposed to occur around 9:30 Central European Summer Time (3:30 a.m. Eastern, if I have done the math correctly) on Wednesday. Call it Tuesday night, for us West Coasters.

The folks at the History Channel recognize the importance of the event, and they’ve recruited Friend of CV David E. Kaplan, a particle theorist at Johns Hopkins, to host a special show entitled the Next Big Bang. And we, of course, have recruited David to tell you a little about the show. (In the picture, David is the one wearing glasses.)

(p.s. This LHC game is surprisingly educational. Via DILigence.)

Update: Hey, I guess this is a preview? Well, not of the History Channel documentary in particular, but closely related (and see David struggling with a bad hair day). Via symmetry breaking.

—————————————————-

Hello All. This post represents shameless advertising for a television program which I am hosting on the History Channel this week. The show is a one-hour program about the Large Hadron Collider (LHC) experiment outside of Geneva and will air the day before the first proton bunch circulates the entire 27 km ring (September 9th, 8pm/midnight EDT/PDT, 7pm/11pm CDT, 6pm/10pm MDT). The show will visually describe the complexity and scale of the experiment and some of the potential discoveries we hope to make (the Higgs particle, supersymmetry, dark matter, extra dimensions).

For many reasons this is an amazing moment in the history of science (many which have probably been repeated on this blog before). [Indeed — ed.] There are roughly 75 countries with at least one institution (university or lab) which has contributed to the construction of this machine. The list includes strange bedfellows: India and Pakistan, Israel and Iran and the United States, Greece and Turkey, Russia and Georgia, all of western Europe, most of eastern Europe, some of northern Africa and south America, Japan, China, S. Korea, etc. This unlikely team has constructed the biggest single machine in the history of the planet after over 20 years since the first plans were laid. At 10,000 scientists, this project represents the modern day pyramids.

What gets me though is that high-energy physics have not really seen a discovery that has directly shaken the standard model of particle physics for thirty years. The discovery of neutrino masses were a surprise, but fit nicely in the standard model if there is new physics at (unreachably) high energies. Dark matter was certainly a surprise, but could potentially only couple to us gravitationally, and again not uproot the standard model. The same can be said about dark energy to an even greater extreme. However, an unexpected particle has not been discovered since the seventies. The seventies were the time that not only the standard model was discovered experimentally, but its underpinnings, quantum field theory, was confirmed as the correct underlying description of all matter interactions (other than gravitational). The (perhaps, not so) amazing thing is, the surprising discoveries stopped by the end of the seventies, and we have been confirming the standard model even since.

The implication is that almost the entire particle physics community, both theorists and experimentalists, who are actively working on LHC physics have never been involved in a surprising discovery. This large community of scientists have been building up to this moment for their entire careers. The scale of these experiments are such that one can really only expect one discovery per generation, and this one is ours.

The show is not perfect, but there are some stunning analogies. I did not write the show, but I fact-checked most of it. There is no attempt to scare the viewer with ‘disaster scenarios’, but simply an attempt to cover what the physicists are constructing and what they expecting or hoping to discover. There is also a bit of history of particle physics.

Enjoy the show. I’ll stay connected so I can answer any questions that come up.

Street Corner Science with Leon Lederman

ScienCentral is an interesting organization. They are a production company that focuses, unsurprisingly, on science. The kind of thing they will do is to haunt the hallways of a big science conference, and snag interviews with scientists, and then turn them into short news stories that can play on local TV stations around the country (and be seen by millions of people in the process). And of course they do longer-form pieces as well.

And now they have been upgrading their web presence, and the site has a lot of goodies (including a nascent blog). Here is a fun clip featuring Leon Lederman sitting on the sidewalk and answering science questions from passers-by. (This doesn’t usually happen.)

Stories of Sizzling Science

So why didn’t I think of this? Marine-biologist-turned-filmmaker Randy Olson has a new movie coming out — Sizzle: A Global Warming Comedy — and has asked a bunch of bloggers to simultaneously post reviews, to generate some buzz out there on the internets. (Full listing here.) Next time I have a movie coming out, I’ll have to come up with something even more clever.

Disclaimer: I’ve met Randy a couple of times, and he handed me a review copy of the DVD (premiere is this Saturday) at the conclusion of an enjoyable Mexican dinner with a bunch of local science/media folks. None of this, of course, compromises my unswerving devotion to completely objective fairness, but the rituals must be observed.

This is a movie with a goal, and it’s fair to ask how well it achieved that goal. To which I would answer: so-so. I thought the execution was a bit rough in spots, to be honest. It was clearly done on a shoestring budget — a running gag was the search for a famous celebrity spokesperson, and a couple of C-list celebs were dutifully trotted out (with captions so you knew they had appeared on TV), but nobody is going to mistake this for a Spielberg film, or even a Michael Moore film.

Nevertheless: the goal was awesome! Namely (as I see it, maybe Randy would disagree), to make a movie about a scientific topic that would be interesting and perhaps even gripping to an audience that would generally not show up at movies about science. In particular, to make a movie with an actual narrative — one with characters, that told a story, all in the service of a scientific purpose. Sizzle is not a lecture, nor does it pretend to be. On the contrary, another running gag is the famous inability of scientists to cast their message in the form of a gripping story when they could instead take refuge in data-filled plots and multiply-qualified conditional statements.

Which is great. Communicating generally, and storytelling specifically, are very particular skills that take a lot of effort to master. Too many scientists don’t think the effort is worth it, or are simply convinced that this is a skill they have already perfected. The best thing about Sizzle is that it proves the existence, by construction, of an alternative model. This movie has a story, featuring actual characters, and — best of all — the characters actually learn and grow and change during the course of the film. All in the service of conveying a scientific message!

Unfortunately, I don’t think the message is successfully conveyed. The movie ends up reacting so strongly against the traditional pitfalls of misguided scientific presentations — too much data, too little drama — that it falls victim to the complementary pitfalls. At the end, I wasn’t sure why I should believe that global warming was a real problem, outside of some appeals to authority (these scientists sure are trustworthy, aren’t they?) and emotional gestures (polar bears are cute! the aftermath of Katrina was sad).

So I commend Randy and the other people involved with Sizzle for trying to break the mold of traditional scientific discourse, and for reaching out to new audiences. But I think that there is a tricky balance that has yet to be successfully struck: on the one hand, respecting the science, and being honestly informative without hedging the truth in the service of persuasion; and on the other, telling a compelling story that draws people in without giving them the feeling that they are being forced to eat their vegetables.

Science is full of drama, excitement, and gripping stories. Making that excitement accessible to the wider world is by no means a simple thing, but it’s worth the effort.

What Do You Say?

Here is a Q&A interview with me in the LA Times, to which I link only reluctantly, as somehow they managed to take a picture that makes me look like I’m wearing a bad toupee. And a halo! So that’s a mixed bag.

The interview was spurred by the recent Scientific American article on the arrow of time, and most of the questions are pretty straightforward queries about entropy and cosmology. But at the end we veer into matters theological:

Does God exist in a multiverse?

I don’t want to give advice to people about their religious beliefs, but I do think that it’s not smart to bet against the power of science to figure out the natural world. It used to be, a thousand years ago, that if you wanted to explain why the moon moved through the sky, you needed to invoke God.

And then Galileo and Newton came along and realized that there was conservation of momentum, so things tend to keep moving.

Nowadays people say, “Well, you certainly can’t explain the creation of the universe without invoking God,” and I want to say, “Don’t bet against it.”

I’m not really surprised that people bring up God when asking about cosmology; the subjects are related, like it or not. But I really do want to separate out the science from the religion, so in the context of an interview about physics I’m reluctant to talk about the existence of God, and I haven’t really perfected an answer when the subject comes up.

Anyone who reads the blog might be surprised to hear that I don’t want to give people advice about their religious beliefs — I do it all the time! But context is crucial. This is our blog, and we write about whatever we’re interested in, and nobody is forced to read it. Likewise, if I’m invited to speak or write specifically about the subject of religion, I’m happy to be perfectly honest about my views. But in a context where the explicit subject is supposed to be science, I would rather not bring up God at all; not because I’m reluctant to say what I believe, but because it gives a false impression of how scientists actually think about science. God just doesn’t come up in the everyday activities of a working cosmologist.

This was the second recent incident when I was prodded into talking about atheism when I would have liked to have stuck with physics. At my talk in St. Louis in front of the American Astronomical Society, I was introduced by John Huchra, the incoming AAS president. He had stumbled across “Why (Almost All) Cosmologists Are Atheists,” and insisted that I tell everyone why. So I gave a version of the above argument, presumably in an equally clumsy fashion: whether or not you choose to be religious, it’s a bad idea to base your belief on natural theology (reasoning towards God from evidence in the physical universe), as science has a way of swooping in and explaining things that had previously been judged inexplicable by purely natural means.

And I think that’s very true, but I think something stronger as well: that claims about God can be separated into two classes — (1) those that are meaningless, and (2) those that can be judged by standard criteria for evaluating scientific claims, and come up wanting. But it’s an argument I just don’t want to force on an audience that came for some science. After all, there are plenty of claims that I think are true, but I don’t feel an urgent need to insist on every single one of them in every imaginable venue.

For example: with the acquisition of a reliable low-post presence in the form of Elton Brand, the Sixers will be challenging for the Eastern Conference title this year and for the foreseeable future. Undoubtedly true, and an important fact about the universe that everyone should really appreciate, but not something I’ll be bringing up at my next physics seminar.
