La particella di Dio

This is one of the two or three best documentaries I've ever seen. We were so lucky to see an advance screening at our movie preview club.

It's hard to believe that a documentary about particle physics and the Hadron collider could be dramatic, suspenseful, even thrilling. It's just as hard to make the subject matter - the creation and operation of a huge facility in Switzerland for the purpose of colliding sub-atomic particles at great speed to search for clues about the universe - both intelligible and accessible. Yet this film has brilliantly done both.

Accessibility is achieved partly through clear explanations from particle physicist (and co-producer) David Kaplan and other theoretical physicists, and several experimental physicists who work at the collider. Even more compelling are the clear, beautiful, and simple-to-understand graphics that accompany these explanations. Indeed, the great graphics begin right from the opening credits. All this is enhanced by the editing of multi-Oscar-winner Walter Murch.

The drama comes from the efforts of the experimentalists to prove the theorists' ideas true - especially the existence of the "Higgs boson," the crucial particle of modern physics. The drama is enhanced by presenting a pleasant cast of surprisingly normal, friendly (and, of course, super-smart) physicists who have strong rooting interests in the outcome the way some of us might root for a sports team - but with so much more at stake. There's even tension (albeit friendly) between the "multi-universe" and "dual symmetry" camps.

Watch this film and you'll understand these phrases and so much more. I learned more than I ever thought I could. And in the most pleasant, enthusiastic, accessible way possible.

The main focus of this film is the interaction of scientists with the LHC and its data. Many shots are either banter in the CERN offices or YouTube-like video contributions from scientists themselves. Basically, it adds a human element to what you might read in the news. The engineering of the LHC is scarcely touched upon, and while the film (directed by a physicist) attempts to explain the consequences for particle physics, its dramatized overview is not really accurate; the viewer would be advised to read Lee Smolin's book "The Trouble With Physics". The substitution of pictures of difficult-looking math equations for real scientific exposition became irritating. Furthermore, while we see people interacting with each other in a superficial way, the film doesn't really dig into the culture of theoretical physics -- for example, I enjoyed a shot where physicists discuss how rumors are displacing older methods of data distribution like the arXiv, but the context of this discussion was not given and I worried most of the audience would not understand it.

I subtract four stars for lack of depth and would probably extract more, except that the screening I went to had an interview with the director afterwards, and I realized from him that it was quite difficult for this documentary to achieve what it did. The science the LHC produces comes in the form of millions of spreadsheets full of numbers, which must be analyzed by thousands of experimental physicists sitting at computers around the world. It is rather hard to make a long documentary film about people analyzing numbers on computers. The director made a number of clever stylistic decisions, like mainly interviewing people who were physically present at the CERN buildings, and separating the segments of experimental and theoretical physicists. To get theoretical physics onto the big screen in a thoughtful and entertaining way is really an accomplishment in itself. It was also pointed out that the documentary skillfully focused on a few likable subjects among many to give a hint of the vast size of the project. All in all, the film is a decent portrayal of the kind of willpower and teamwork that is needed on a project the size of the LHC, but don't go to it expecting to gain a very deep knowledge of today's physics or the scientific community.

I generally evaluate films on their technical direction and production values, not necessarily their deep meanings -- because as a student of film and a video producer, I know how subjective those "deep-meaning" criteria can be.

I found this film to be an exciting, well-crafted, exceptionally well-edited and sound- designed production. No one in the audience seemed ready to drop off as is so often the case with documentary features. Instead, the director's timing was precise and the arc of the story very well formed. But there was much more happening in this movie below the surface.

The Hadron Collider is as one figure in the film indicated, the largest machine ever constructed by human beings ("machine" being meant as a mechanical unit, not a network like the Internet -- although even the Internet was essential to the successful use of the Collider, to distribute all of the data generated to various locations where it could be processed and analyzed). The drama of its conception was left a little vague, but from the time that construction began to the time it was used to look for the Higgs Boson, the characters involved are well portrayed and their motives thoroughly probed -- in an amazingly short time!

The physics behind the quest for the "God Particle" are not all that hard to understand and besides, the film does a great job of simplifying even further so that anyone with a basic high school education should be able to follow the story and its implications.

I particularly enjoyed the "main" characters, some of the key thinkers whose speculations as physics "theorists" fired the imagination of physics "experimentalists" who are driven to test the others' speculations. The give and take between the two communities gave the film its energy and tension. I hope there will be sequels following down the next round of experiments, to take place in Sweden, where an even bigger collider is being built -- and also the physicists, how their lives are turning based on the results gotten from this unique, massive exploration of the fundaments of existence itself.

PS PARTICLE FEVER is not all youthful, bubbly energy and joyful discovery. The stories of the older physicists, facing their retirement from the field possibly without ever finding elusive answers to questions they posed decades earlier in their lives, was real hankie material -- and for good reason. In the field of particle physics, like other achievement-driven/self-promotional professions, it's not how smart you are but when you're smart, if luck is on your side and you timely get noticed, validated, and lauded. Miss the mark, and you may be relegated to obsolescence even if your mind is still active and your ideas large. Fortunately in this case, most of those with long-ago aspirations have lived long enough to have their ideas tested and thus learn their truth.

Interesting how personal meaning and the meaning of the universe -- or multiverse, according to one theory tested by the Collider -- are so intertwined. And which really is the more important, a question about which there is no easy answer.

See this film, you will emerge glad for the experience, with big questions yet to be answered.

This is a documentary that physicists will love, as will others who really love science. It's the kind of film that carefully explains the difference between theoretical and experimental physicists. If that kind of distinction interests you, then you will like the film. A lot of physics jargon is tossed around in this film with no explanation so you need to bring a working knowledge of particle physics if you want to fully understand the discussions. If you don't know what a GeV is and that lack of knowledge is going to bother you, then you will not like this film. If you enjoy an explanation of the opposing physics theories of supersymmetry and the multiverse, then this is your film. Also, if math scares you, there are blackboards and whiteboards full of some of the hairiest equations you're likely to see. If you find such things frightening, just turn away.

However, if you'd like to meet people who have staked 10, 20, 30, even 40 years of their career on the moment when the ATLAS team finally announced "We've got it!", then this film is for you. This film paints an accurate though relatively lightweight picture of the years spent making the world's largest machine, the LHC (Large Hadron Collider), operational and then confirming the existence of the Higgs boson 40 years after it was predicted in theory. It's exciting to see scores of smart people stretching their brains to the limit so that they can understand something truly fundamental about the universe.

Although billions of particles were smashed in the LHC experiments needed to confirm the Higgs, you will mostly see calm scenes of crops growing in the LHC's vicinity. There are no car chases or crashes, no battling giant robots, no aliens. There are just lots of smart people saying highly intelligent things, most of the time. When they drop into small talk or take time out to brew an espresso, it's actually jarring. (At least it was to me.) About the audience: There were about 40 people in the movie showing I attended on a Sunday afternoon. Every single one of them looked like they had an advanced degree in physics or some other hard science. Indeed, that's who this movie is made for.

Since real science gets very little public exposure in any positive way, anticipation was high that this would help deliver that. While it made a credible attempt, I was rather disappointed at the lack of balanced credit. To the average public citizen it came across as largely the work of a few visionaries and one particular experiment - ATLAS. There were several others who did major yeoman like efforts and that is why I gave it only 6 stars. The human stories were particularly good, perseverance despite the adversity, it could have easily done it without the expletives as well. While it is a documentary and did a fantastic job of chronologically growing with the major real life characters, it failed to acknowledge numerous labs and institutions, along the way who were much more than mere influencers. But definitely worthwhile, hope the next generation of the story raises the bar.
