The Life of a Scientist:
Fermi exhibit in library

In a 1954 talk, Enrico Fermi presented a futuristic vision of an accelerator that would encircle the earth and achieve energies never fathomed by scientists. Image courtesy of the Special Collections Research Center, University of Chicago Library.

An exhibit chronicling the life of the Nobel-winning physicist Enrico Fermi is currently on display in the Fermilab library. The exhibit, entitled "Enrico Fermi: The Life of a Scientist," includes reproductions of personal and scientific photographs and documents from Fermi's celebrated life. Our own National Accelerator Laboratory was renamed in his honor 1974.

Enrico Fermi

Fermi was widely known as the father of the Atomic Age for his contributions to the fields of particle theory and nuclear physics. After winning the 1938 Nobel Prize for Physics, Fermi and his family emigrated from Italy to the United States. His work on the Manhattan Project at the University of Chicago in 1942 produced the first self-sustaining nuclear chain reaction.

With the help of Fermilab's Visual Media Services, Giorgio Bellettini of CDF developed the exhibit for its inaugural display in September 2001 in honor of Fermi's 100th birthday. The exhibit includes documents and images from the Physics Department of the University of Pisa and the Enrico Fermi Institute at the University of Chicago. Archivist Adrienne Kolb also supplied additional artifacts from the Fermilab History and Archives Project.

The exhibit will be on display in the Fermilab library until July. Employees and users can borrow various books by and about Fermi, as well as a DVD of the Italian film, "Science at Pisa: Enrico Fermi."

What is behind the mysterious force we call dark energy? One way or another, it will overturn our idea about how the universe works

Every now and again cosmologists decide that the universe needs redecorating. Sometimes they declutter, as when Copernicus and Kepler shuffled the sun and the Earth to get rid of all those epicycles and make the planets move in straightforward orbits. Sometimes they embellish, as when Einstein decided that there's more to space than good old-fashioned nothingness, and introduced the concept of a deformable space-time.

The ILC: Gateway to the Quantum Universe

This column is written by Barry Barish, director of the ILC Global Design Effort.

The Terascale promises to revolutionize our views of the universe.

In addition to the technical reports released last week in Beijing that describe the reference design for the ILC, we also published in draft form a very attractive and informative companion document, "The International Linear Collider: Gateway to the Quantum Universe." It can be downloaded in pdf format.

The Reference Design Report (RDR), the Detector Concept Report (DCR) and this companion piece will all be published in final form this coming summer, after reviews and modifications are incorporated. The companion document tells the story of the ILC by those involved in designing and planning it. The document translates the technical and detailed materials for a much broader audience.

ILC Physics: The analysis
has already begun

For the proposed International Linear Collider, physicists are trying to both design the most precise calorimeter ever and still be able to afford it. A calorimeter measures the energy of particles in a detector, and is typically the single most expensive part. If you reduce its performance slightly to reduce costs, how much have you sacrificed?

One way to answer that question is to calculate the mass of the undiscovered Higgs particle. It may sound like a non sequitur, but analyzing data produced from simulated particle collisions gives a good idea of how sensitive the experiment remains to important physics.

"We are studying physics processes that are sensitive to the new detection method that the calorimeter will use," said physicist Tim Barklow. "We want to know how important it is to achieve the unprecedented precision in the calorimeter that we're attempting to achieve."

Barn Dance
There will be a Fermilab Folk Club Barn Dance Sunday, February 18 at 2 p.m. with music by the Common Taters and calling by Allan Sundry. More information

You can help stop local shortage by giving blood, Feb. 19-20
Except for AB Positive, Heartland Blood Center inventories of every blood type have dropped to less than a two-day supply; putting patient's surgery and treatment in jeopardy. You can donate blood at Fermilab February 19 and 20, from 8 a.m.-2 p.m. in the Wilson Hall Ground Floor Training Room. Appointments are suggested, but not required. To make an appointment, visit the ES&H website.
