The sixth of our PhysicsMeetup events, hosted by the Physics Department of Central Mindanao University, Bukidnon, Philippines, is taking place on  Wednesday 30 June at 1:30 AM Italian Time (8:30 AM Philippines Time).

This virtual event will be held via zoom and livestreamed on Facebook. For further information on how to access the event, kindly visit https://www.facebook.com/physicsmeetup

About the Talk:
One of the most misunderstood aspects of the flight of airplanes (and birds) is the drag force - the force that the air exerts to oppose the motion of the airplane. Part of the drag force is what we commonly call "air resistance"; (the force you feel on your face when running or bicycling). But another important part is induced drag, which is an unavoidable byproduct of the lift force produced by an airplane's wings. Unlike air resistance, induced drag becomes more important the slower the airplane flies!
In this illustrated talk, Prof. Freedman will explore both kinds of drag and see how their properties explain the shapes of airplane and bird wings.
The talk is suitable for first-year undergraduates as well as professional scientists (and you don't need to have seen his previous talk on May 29!).


 

About the Speaker:
Roger Freedman is the co-author of several best-selling textbooks, including University Physics (Pearson), College Physics (Macmillan), Universe (W. H. Freeman), and Investigating Astronomy (W. H. Freeman). Prof. Freedman is a teaching professor in physics at the University of California, Santa Barbara. He was an undergraduate at the University of California campuses in San Diego and Los Angeles, and did his doctoral research in theoretical nuclear physics at Stanford University. He holds a commercial pilot’s license and is academic advisor to UCSB Women’s and Men’s Rowing. He was an early organizer of the San Diego Comic-Con, now the world’s largest popular culture convention, and today is a member of the board of directors of San Diego Comic Fest, an annual convention that recaptures the spirit of Comic-Con in its early years. He has appeared as a mad scientist and supervillain in both Marvel and DC comics.
