January 1, 2015. Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. Its content reflects the fact that my interest lies in history and philosophy of science and that I teach in a Department of History and Philosophy of Science. This text owes a lot to many. i i i
Boston chemist wins Houston-based Welch Award A Boston scientist who harnessed the power of nuclear magnetic resonance to elucidate the structure of molecules has won the 2011 Welch Award in Chemistry, a prestigious prize given by the Houston-based Welch Foundation. The tools devised more than four decades ago by Massachusetts Institute of Technology chemist John Waugh, 82, are still used in labs today. "Dr. Waugh discovered how to use NMR to study solids, creating a collection of tools that allows researchers to view the structures and properties of proteins, membranes, viruses and many other critical components of life," said Ernest Cockrell, chair of The Welch Foundation. "Ultimately, new applications in fields as diverse as medicine and batteries can trace their way back to the research techniques he initiated." The award carries a $300,000 prize, and Waugh will receive a gold medallion at a ceremonial dinner on Monday night. "It opened up the possibility of determining molecular structure," Waugh said.
Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. Many animations have been translated into Greek by Vangelis Koltsakis. Most animations have been translated into Hungarian by Sandor Nagy, Eötvös Loránd University.
The Dvorak Keyboard -- a Primer Aerodynamics (Mechanics of Flight)--Science Tracer Bullet Tracer Bullet 00-3 Aerodynamics is the science that deals with the motion of air and other gaseous fluids, and with the forces acting on solid bodies when they move through gaseous fluids, or when gaseous fluids move against or around solid bodies. Therefore aerodynamics comes into play when air is flowing over airplanes, automobiles, cars, ships, buildings, and other objects. Aerodynamics also comes into play when air is flowing through ducts or other enclosed spaces such as wind tunnels, jet and rocket engines, and pipes. Anderson, John D. Datta, Sreela. Wegener, Peter P. Subject headings used by the Library of Congress, under which books on aerodynamics can be located in most card, book, and online catalogs, include the following: Anderson, John David.

The Elegant Universe: Series ... The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination. This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything." Our guide to this brave new world is Brian Greene, the bestselling author and physicist. BRIAN GREENE (Columbia University): And no matter how many times I come here, I never seem to get used to it. NARRATOR: Can he help us solve the greatest puzzle of modern physics—that our understanding of the universe is based on two sets of laws that don't agree? NARRATOR: Resolving that contradiction eluded even Einstein, who made it his final quest. S. BRIAN GREENE:The atmosphere was electric. S. S.
Polyphasic Sleep A couple days ago, I saw a post about polyphasic sleep on LifeHack.org. Since then I’ve been emailed about this topic as well, probably because I’ve written previously about becoming an early riser. Polyphasic sleep involves taking multiple short sleep periods throughout the day instead of getting all your sleep in one long chunk. A popular form of polyphasic sleep, the Uberman sleep schedule, suggests that you sleep 20-30 minutes six times per day, with equally spaced naps every 4 hours around the clock. This means you’re only sleeping 2-3 hours per day. Under this sleep schedule, your sleep times might be at 2am, 6am, 10am, 2pm, 6pm, and 10pm. How can this sleep schedule work? It requires some discipline to successfully transition to this cycle, as well as a flexible schedule that allows it. It was interesting to read some of the posts from people who’ve tried this sleep cycle. The downside to this sleep schedule is that it can be inflexible. Plus it’s just plain weird. Sleep well!
