In 1990, Penny Kasper, Danying Yi and I were all graduate students on the E791 experiment. Part of the detector, controls and data acquisition system had been modified from the previous experiment, E769, so everything had to be tested before we got the first beams.
Jean Slaughter, who was in charge of the day-to-day operation of the experiment, announced we would have a “dress rehearsal.” Being a non-native English speaker, I had no clue what that meant. I asked Jean what would I have to do. She simply replied: “Just stand there and look pretty.” So I decided to take it literally and convinced Penny and Danying to join in.
Just before the dress rehearsal, we all snuck out and came back to the control room dressed to the nines. Penny wore her best dress, Danying put on the special wedding dress her mother had sent her from China (hoping to encourage her to get married), and I wore my mother’s copper satin wedding dress.
When we showed up in the control room, our colleagues all looked puzzled. Most had a great laugh, even though I suspect many of them just thought we were plain nuts.

Fermilab’s Superconducting Quantum Materials and Systems Center is announcing a new fellowship opportunity for Black and African American postdoctoral scholars. The Carolyn B. Parker Fellowship honors the legacy of the first African American woman to earn a postgraduate degree in physics.
A brief history of women of Fermilab
No aspect of Fermilab, past or present — the accomplishments of the Tevatron, the popular Arts and Lecture Series, the education efforts, the world-leading neutrino program — would be what it is today without the contributions of women. This International Women’s Day, we honor their contributions.
Twenty-fifth anniversary of the discovery of the top quark at Fermilab
Twenty-five years ago, scientists on the CDF and DZero particle physics experiments at Fermilab announced one of history’s biggest breakthroughs in particle physics: the discovery of the long-sought top quark. The collaborations on the two experiments jointly made the announcement on March 2, 1995, to much fanfare. We take a look back on this day in Fermilab history a quarter-century ago.
