Prof. Leonard Kisslinger is the co-awardee of the first Mark Gelfand Service Award for Educational Outreach. Since 1998, Leonard Kisslinger has led the Carnegie Mellon Physics Concept Program. Middle school students from Pittsburgh Public Schools interact with undergraduate students, graduate students and faculty from the university to study fundamental physics concepts in an effort to provide the children with hands-on experience on how scientific research is carried out.

Data from this collider will answer important questions, such as the dominance of matter over antimatter in the universe. By now, most people in America have heard about "Deflategate," where the New England Patriots are alleged to have used underinflated footballs during the AFC championship game against the Indianapolis Colts.
While some believe the Patriots' footballs were tampered with, others have suggested that a change in temperature may have caused the Patriots' footballs to lose pressure. Carnegie Mellon Physics Professor explains how physics could have played a role in football's latest controversy.
"It's pretty simple physics," Franklin said. "If you pump up a bicycle tire using air from a warm room and then take it outside on a cold winter day, you'll find that the pressure in the tire decreases as the air in the tire cools off. The air pressure in a football is no different.
"If a football is inflated to the minimum pressure allowed by the NFL-12.5 pounds per square inch-using warm air, the football's pressure will drop below this minimum value as the air cools."
Could this possibly be part of the answer to Deflategate?
Franklin said that, by rule, a decrease in temperature will correspond to a decrease in pressure. For example, if the air temperature decreases by 10 percent, the pressure in an inflated object, such as a bicycle tire or football, will decrease by 10 percent.
This law can be used to calculate what would happen if the air pressure in a football was measured before a game in a nice warm room, perhaps at 72oF or higher, and then measured again after the football cooled to an outdoor temperature in the mid-40s.
At first glance, this might sound like it would have a huge effect — about a 40 percent reduction in temperature — but Franklin said to be careful. Physics doesn't operate in Fahrenheit. To do the calculation correctly, Fahrenheit readings need to be converted to numbers that measure the temperature relative to absolute zero. When this conversion is done, the temperature of the football decreases by only about 5 percent.
So what does a 5 percent decrease in temperature do to a football initially inflated to 12.5 pounds per square inch (psi)? While it's tempting to say that the pressure drop will be 5 percent of 12.5 psi, this would be incorrect. The pressure measured by the pressure gauge, called the "gauge pressure," is actually the pressure difference between the air inside the football and the air in the surrounding room.
