摘要:Giraffes face unique challenges for drinking due to their long necks. In this article we use evidence from videos, size estimates, and elementary fluid mechanics to make a strong case for a plunger pump mechanism moving water up from their lips to their shoulders.

摘要:In September, we looked at participation in high school physics by race and ethnicity, and we have provided two different views of physics in high school by socioeconomic status (SES). This month, we consider the proportion of seniors attending schools by race and SES. About...

摘要:November 10, 2015, marked the 40th anniversary of the sinking of the S. S. Edmund Fitzgerald , a Great Lakes bulk cargo freighter that suddenly and mysteriously sank during a severe winter storm on Lake Superior. A year after the sinking, Canadian folksinger Gordon Lightfoot...

摘要:“What we don't understand, we explain to each other” was Robert Oppenheimer's 1948 description of theoretical physics as a profession. Because the phrase connects research, teaching, and learning, it seemed the right approach for the talk I gave to the AAPT on receiving the ...

摘要:Doing experiments in physics lessons can create a magical moment if students become really intrigued with the experimental progression. They add a new quality to what the experiment shows. Their attention and nature's revelations flow together: a performance is taking place....

摘要:My favorite exam question comes from the final exam in an introductory mechanics course: A rolling 31 ton railroad boxcar collides with a stationary flatcar. The coupling mechanism activates so the cars latch together and roll down the track attached. Of the initial kinetic energ...

摘要:The concept of “seeing by feeling” as a way to circumvent limitations on sight is universal on the macroscopic scale—reading Braille, feeling one's way around a dark room, etc. The development of the atomic force microscope (AFM) in 1986 extended this concept to imaging...
