Alfred K. Mann was known to the public for his decorated career in particle physics, and to his family members as a student of history and literature who quoted Cicero at the dinner table. More than a decade after retiring from the University of Pennsylvania, Dr. Mann, who died Sunday, Jan. 13, at age 92, added another line to his resumé: protester. In 2003, Dr. Mann helped organize a campaign against the proposed closure of an 8,000-foot-deep South Dakota gold mine that was seen as an ideal site to measure the subatomic particles called neutrinos.

On Canaan's Side by Sebastian Barry (Viking, $24.95) The lyrical, award-winning novelist depicts Depression-era America through the eyes of Lilly Bere, a political refugee from Ireland. (Sept. 6) Sister Citizen: Shame, Stereotypes, and Black Women by Melissa V. Harris-Perry (Yale, $28) The author, a professor of political science at Tulane University, explores how black women negotiate the many images society throws at them. The personal really is the political - and vice versa.

The visionary architect Lebbeus Woods wonders what would happen if buildings and cities sought to embody the "ethereal energies and exotic matter" of modern physics rather than "comfortable ruminations in the past. " He believes it is reassuring - but wrong - that architecture reflects the primitive, mechanical common sense codified in ancient times by Euclid and Aristotle, rather than the altogether more enigmatic world that has been revealed by a couple of centuries of progress in physics.

Norman Ramsey, 96, who shared the 1989 Nobel Prize in physics for his research into atomic energy levels that led to the creation of the atomic clock and MRI machines, died Friday at a nursing home in Wayland, Mass., his wife, Ellie, said Monday. Mr. Ramsey was an emeritus professor of physics at Harvard University. In his autobiography for the Nobel Prize - which he shared with Hans Dehmelt and Wolfgang Paul - he wrote that he was inspired by failure in molecular beam magnetic resonance experiments in the late 1940s to invent a new technique of measuring the frequency of radiation from atoms using two electromagnetic fields.

Students in Rosalind Echols' physics class at the Science Leadership Academy think about what they're learning even when they're not in school, like when they're playing soccer, or taking SEPTA. "While I'm running on the soccer field, I'm thinking about whether I'm accelerating in my speed, or whether I'm in constant velocity," said Ashley Melendez, 17, a junior at the Center City magnet school. Echols' students think about physics on SEPTA trains, buses and trolleys because she uses her students' travels to help them understand Isaac Newton's Laws of Motion.

In contrast to Proof's and Copenhagen's more high-minded dramatic forays into abstruse reaches of math and physics, Schr?dinger's Girlfriend insists there's an element of the farcical in the subatomic particle. But for all its offbeat iconoclasm, Matthew Wells' comedy takes a quantum leap to nowhere in particular. Wells deserves credit for having the titans of 20th-century physics step off their pedestals to show that beautiful minds can also be prey to lusting hearts. Instead of awed canonizations, we have Werner Heisenberg popping up to reinforce his uncertainty principle by insisting he's not really present on the stage of the Act II Playhouse in Ambler.

The world of physics was rocked mightily last week with the announcement that a new force may exist in the universe. If experiments show that the new force - known as hypercharge - does exists, the findings could have far-reaching implications on everything from the birth of the universe to black holes to attempts by physicists to link all of the known forces into one overall "grand unified theory. " The new theory challenges Galileo's observation in the early 17th century that all objects fall to earth at the same speed.

Pumpkins were flying through the air outside Conestoga High School as students watched anxiously. Only one pumpkin didn't survive, and its remains were splattered below the bleachers at Teamer Field. The event, held recently, was the second annual pumpkin flop held by the Physics I class. "The object was to get the students to construct a container or a device which will slow down the pumpkin's fall," said physics teacher Kathleen Conn. "The students were given rule sheets and several weeks to design their containers/devices.

The 21st century - you know, the one where technology is supposed to rule - could end up looking an awful lot like the 19th in Wyoming, where the state university is considering a plan to eliminate its physics programs. That would make Wyoming's the only state university system in the country not to offer a physics degree. This in a state that already ranks dead last, behind all the other states and Puerto Rico, in technology-related jobs - for many of which physics is a prerequisite.

As a physics teacher at the University of Rochester in 1963, he spent a year in Argentina, helping the government there set up an atomic research installation. As an expectant father in 1966, he took his wife on a teaching assignment to India, where their first child was born. "It shows the adventurous spirit that both he and I had," Larissa Bilaniuk, professor or radiology at the University of Pennsylvania, said of her husband. On Friday, Oleksa M. Bilaniuk, 82, emeritus professor of physics at Swarthmore College, died of brain cancer at his home in Wallingford.
