Cosmological Cinema: Particle Fever



Director: Mark Levinson

Johns-Hopkins physicist and now film producer David Kaplan brings the historic search for the Higgs Boson particle to the big screen, which might lead a film-goer to ask: how cinema-friendly is particle physics and why would anyone want to watch physicists from around the world gather to view the results of a particle-smashing experiment at the Large Hadron Collider in Cern? To answer both questions in turn: 1) apparently very friendly and 2) because it's exciting and worthy of the world's attention. If only physicists and scientists received the media attention showered on clods like the Kardashians, films like Particle Fever might be commonplace but unfortunately 21st century America is light-years from that enlightened attitude.

The Higgs Boson particle was first theorized in 1964 by physicist Peter Higgs but it was only in July of 2012 that its existence was confirmed after a test at the Large Hadron Collider in Switzerland. To fully explain the significance of the discovery and its meaning is beyond my reach so I will include a link at the end of this post.

The film is effective in creating the tension and drama leading up to the experiment, which involved physicists from over 100 countries and technicians by the score. We hear from many physicists from the theoretical side and the experimental. The two camps are aware how mutually dependent they are but one detects a mild, almost sardonic regard the two fields bear for one another. Kaplan himself, with colleague and mentor Nima Arkani-Hamed--both theoretical physicists and academics--discuss the implications of the Collider experiment but the film also shows them in more human moments; playing ping-pong by utilizing a wall rather than a net and discussing the randomness of a university campus sculpture consisting of what looks like small slabs of flagstone.

We also meet many of those involved in the experiment as the big day approaches; a moment watched with bated breath by theoretical and experimental physicists alike, world-wide. One such person is Monica Dunford, an American physicist connected to one of 4 sub-experiments attached to the main particle-smashing event. Dunford discusses how she became involved in the experimental side but we often see her outside the Collider complex, running and biking and engaging in mundane, everyday tasks, which forms a sharp contrast with the abstract (but actually very concrete) world she often explores.

The experiment, after some technical setbacks, proceeds and ultimately succeeds, making front-page headlines world-wide and bringing some well-deserved attention to the extraordinary people who are directly or peripherally involved.

It is explained in the film that two contrasting theories of how the universe is structured would be impacted by the Collider experiment: those who support what is called Supersymmetry and those who support a Multi-verse model (Once again, please refer to links for a better understanding of the two theories). The energy the Higgs-Boson contained would mostly determine which theory offered a more plausible, sub-atomic description of the universe we live in. Theoretical physicists around the world were paying close attention to the data. Unfortunately for both parties, the data didn't support or deny either paradigm.

Watching the film made me wish Particle Fever could be seen on prime-time T.V. If the masses are tuning in to the new Cosmos program, might they also be eager to see Levinson's film? As a friend sitting next to me said, "who would have thought particle physics could be so exciting?" The film also has its touching moments, including the scene when a tearful Peter Higgs is recognized by an auditorium of colleagues and media for his theory; its confirmation only established 50 years after its existence was first proposed! It is certain more implications and discoveries related to the Higgs-Boson particle will be revealed in years to come.

I hope Particle Fever spawns more films in this genre. The world needs them. I also hope the world stays tuned.
