A photograph that won third place in the 2003 AAPT High School Physics Photo Contest for the Contrived Category. This image captures what happens the instant a paintball (fired from a gun) hits the lower part of a balloon filled with water. As the paintball makes contact with the surface of the balloon, the balloon breaks along a single tear, pulling back on both sides. (The photo was taken by Meaghan Tanguay, a student at Noble and Greenough School in Deadham, MA.)


Antoine Dunklin (#88) of John Carroll University outreaches Anthony Tucker (#41) of Wilmington College for an 8-yard touchdown pass. The analysis of controversial football plays is the subject of the paper by Gregory DiLisi and Richard Rarick beginning on page 454 of this issue. (photo credit: Fuchs-Kasperak Photography)


Authors Saalih Allie et al. discuss the teaching of measurement in the introductory physics lab in their paper, beginning on page 394 of this issue. (Appalachian Photo by University Photographer Mike Rominger)


Saffar Arjmandi, Joseph Brinkman, and Terrence Toepker bring push-ups into the physics classroom in their paper, "Physical Push-ups," beginning on page 323 of this issue.


This month’s cover is a close-up of Galileo’s lens (diameter 3.0 cm) in its encasement, date unknown. The crack was due to an unfortunate disregard for the thermal properties of the bronze encasement. The lens, which is on display at the Museo di Storia della Scienza in Italy, is the focus of Harry Manos’s paper beginning on page 268 of this issue.

This month’s cover commemorates the 40th anniversary of TPT with a collage of previous covers. Included are: the very first cover from April 1963, the 10th-anniversary cover (April 1973), showing a likeness of the first editor J.W. Buchta, Harvey White performing a demonstration (Feb. 1983), AAPT’s 1993 move to the American Center for Physics (Dec. 1993), and two of our more recent covers.


This month’s cover shows the gravitational lensing from both luminous and dark matter in the galaxy cluster Abell 1689 distorts the images of more distant background galaxies into so-called "galaxy arcs." The distribution of matter in the universe is among the topics discussed in Lawrence Krauss’s paper "The History and Fate of the Universe," beginning on p. 146 of this issue. Photo Credit: NASA, N.

This month’s cover shows the neo-impressionist painting by Paul Signac, entitled "Barques de Pêche à Marseilles," becomes a useful and fun tool in an introductory optics exercise. See "Physics in the Art Museum," by Daniel Dale and Brenae Bailey, beginning on p. 82 of this issue. (Courtesy of the University of Wyoming Art Museum. The painting is a gift of Dr. and Mrs. Theodore Leshner.)


This month’s cover shows an object that really is “closer than it appears.” Ariel Libertun illustrates how this “real life” example can be used to discuss optical concepts in his note beginning on p. 20 of this issue.


This month’s cover shows “sundogs” positioned on either side of the Sun, with the “upper tangent arc” directly above. These bright patches arise from the refraction of light through oriented ice crystals in clouds. The picture was shot on Kodachrome 64 film using a Nikon F3 camera with a Nikkor 25-50 mm zoom lens. It was made in December 1987 in Roswell, Georgia, looking southwest near sunset. The phenomenon lasted about an hour. Ron Edge explains more about sundogs in his note on p. 522 of this issue.

This month’s cover shows the emission line spectrum of helium as viewed through an uncoated compact disk. At least nine lines are visible, including the prominent yellow line at 587.6 nm. The setup used by Editor Karl Mamola and colleague Joe Pollock to obtain this image is shown in the inset. The optical properties of transparent CDs are the subject of Tim Knauer’s ?Compact Disk Transmission Spectroscope? (beginning on p. 466) and Paul Gluck’s ?Compact Disk Optics? (beginning on p. 468).
