Emily Saltijeral-DeMar: An in-depth look at a deep place

Our tour guide encouraged us to look at our destination, the NuMI tunnel, some 300 feet below. Standing next to the rail, one hand holding my hard hat in place and the other keeping my glasses from flying off, I looked down into what seemed to be a bottomless pit.

Author list

The Collider Detector at Fermilab (CDF) is one of two experiments that record the debris of powerful proton-antiproton collisions at the Tevatron particle collider to explore subatomic processes.

DUSEL mine tour

In March 2007, members of a US National Science Foundation panel went on a whirlwind bus tour of potential sites for the Deep Underground Science and Engineering Laboratory. Here’'s an account of that trip by Peter Fisher of the Massachusetts Institute of Technology.

The wrong stuff

Physicist Brian Cox has been watching science fiction movies since he was a small child. He always scoffed at the imprecise nature of the science in movies. But over the past year, he learned a lot about the balance between making a movie entertaining and making it scientifically correct.

On the trail of cosmic bullets

Do the most energetic particles in the universe come from supermassive black holes? New results from the Pierre Auger Observatory make that case.

Free for all

The next big experiment in particle physics won’t need an accelerator, detector, or other big machine. It doesn’t even involve subatomic particles—unless you count the electrons that flow through electronic circuits, carrying bits of information from one human brain to the next.

Herman Winick: Science and peace

Science is an international activity. It is elementary that communication and collaboration among scientists promote scientific progress. No group has a monopoly on good ideas.

Access to science

The modern age of science was born in a system of patronage and independently wealthy hobbyists pursuing questions that would satisfy their curiosity or fill their pocketbooks.

First HERA collisions

On October 19, 1991, at 6:50 p.m., Bjørn Wiik logged the first collisions in the new electron-proton particle collider at the Deutsches Elektronen-Synchrotron in Hamburg.

RESULTS! The particles of our readers’ imaginations

We asked you to use Roz Chast’s cover of the May issue of symmetry as inspiration to go beyond the elementary particles already discovered or theorized and tell us about the particles of your dreams. The dozens of responses were clever, funny, and insightful.

A night of wonder

Men and women wearing gaudy dresses, looking for customers under garish neon signs—this is a common sight in Kabuki-cho, Shinjuku, a famous entertainment and red-light district in Tokyo, Japan.

BaBar is a video star

Search for “BaBar” on YouTube.com, and you'll get a long list of links to a 1980s TV series based on an animated elephant. But a surprise is hidden among the cartoons—a six-minute film shot in the Stanford Linear Accelerator Center's BaBar control room.

Computing center in a box

Stanford Linear Accelerator Center's newest computing center arrived in a standard 20-foot-long shipping container.

Particles in the sky

What is the universe made of? What are matter, energy, space, and time? How did we get here and where are we going? In particle physics, the classic place to look for answers is in giant accelerators where particles collide. But nature also provides a wealth of data.
