Howard Brody, 83, of Haverford, professor of physics emeritus at the University of Pennsylvania, died Tuesday, Aug. 11, of complications from Parkinson's disease at Bryn Mawr Hospital. Dr. Brody taught physics at the University of Pennsylvania from 1959 until 2000, when he retired. He was interested in the science of sports and, in particular, the physics of tennis. The notion that tennis could be deconstructed from a physics point of view, to help players gain insight and added skill, attracted attention and turned Dr. Brody into one of the sport's leading voices.

D EAR ABBY: My wife is a big woman (not fat). She's an athlete and quite strong. We both enjoy wrestling. We are evenly matched and do it often. Many times she'll pin me down with me on my back, shoulders to the ground. Other times, I do the same to her. The loser takes the winner out to dinner. We enjoy it greatly. Are we crazy? Are we weird? And most of all, are we alone in this activity? - Happy Husband in Florida DEAR HAPPY HUSBAND: As long as no one gets hurt, what two consenting adults do is their business.

The chairman of Temple University's physics department lost his leadership post Friday, one day after federal authorities accused him of illegally sharing sensitive U.S. technology with entities in China. Xiaoxing Xi, a naturalized U.S. citizen, however, would remain on the faculty, officials said. The case against Xi, who was charged with four counts of wire fraud, left colleagues, researchers, and former students perplexed and wondering how the professor they knew as a leading luminary in the field of superconductor research had ended up the latest target in the government's efforts to stanch the theft of trade secrets by China and Chinese businesses.

Update: Temple University said Friday that Xiaoxing Xi has been temporarily suspended as chair of Temple University's physics department, pending the outcome of federal charges that he schemed to provide sensitive U.S. defense technology to China. "The concern is this certainly will affect his ability to do administrative duties," Temple Provost Hai-Lung Dai said. No decision has been made on whether he will be permitted to teach in the fall if the case has not been resolved, Dai said.

THE CHAIRMAN of Temple University's physics department, a world-renowned expert in a complex field that most people know nothing about, has been indicted for fraudulently obtaining key technology to help associates in his native People's Republic of China. Xiaoxing Xi, 47, of Penn Valley, is a whiz in the field of superconductivity, the ability of something to allow electricity to flow through it easily - especially at very low temperatures - which can boost the performance and efficiency of certain technology like MRI machines.

When you get right down to it, it was a question of physics. At the site of the Amtrak derailment on Tuesday, the track had a fairly significant curve. Imagine a giant circle with a diameter of nearly 2,900 feet, more than a half-mile. The track's path would trace the outline of that circle. The track also had a "superelevation" of five inches, meaning the outer rail was five inches higher than the inner rail. Given those parameters, a locomotive pulling seven Amtrak-size cars could safely travel up to about 55 m.p.h., said Pennsylvania State University engineer Steve Dillen, who performed a rough calculation at The Inquirer's request.

The concentrated heat radiating from your laptop. The sudden roar of the cooling fan from inside your desktop computer. Familiar signs of wasted energy, caused largely by the increasing numbers of transistors crammed into the innards of our electronic gadgets. As you reach once again for that charging cable, be aware that an amiable pair of University of Pennsylvania physicists may have hit on the beginnings of a solution: a new kind of material called topological insulators.

For Joe Eisele, it wasn't just about making plays. It also was about making amends. "I was definitely determined," Eisele said after leading St. Augustine Prep to an 11-6 victory over Shawnee on Thursday morning in a clash of the No. 1 and No. 2 teams in The Inquirer's South Jersey Top 10 rankings. Eisele, a senior attack and Delaware recruit, scored four goals and added two assists as St. Augustine Prep emerged with the upper hand in a physical battle between fierce rivals in unseasonably harsh conditions.

Miles Austin revamped his warm-up regimen before last season to shake the "injury-prone" label that now follows the 30-year-old receiver to the Eagles. Austin played the first 11 games of 2014 for the Cleveland Browns without major problems with his hamstring, which forced him to miss 11 games in his final three seasons with the Dallas Cowboys. Then, he suffered a lacerated kidney in the 12th game, ending his season and bringing him onto the free-agent market after another unfinished campaign.

LIKE THE NFL'S endangered extra point, physicals given to players to make signings and trades official tend to be almost automatic. That might not be the case when Eagles doctors give wideout Miles Austin the once-over, though. Austin, who turns 31 in June, last played a full NFL season in 2012 and has a chronic hamstring problem. The NFL Network's Ian Rapoport reported yesterday that the Birds have signed Austin to a 1-year deal worth $2.3 million, with another $700,000 possible in incentives.
