List of trigonometric identities These identities are useful whenever expressions involving trigonometric functions need to be simplified. An important application is the integration of non-trigonometric functions: a common technique involves first using the substitution rule with a trigonometric function, and then simplifying the resulting integral with a trigonometric identity.

AIMS Puzzle Corner: Free Math Puzzles This week’s Puzzle Corner activity is a magic trick with a mathematical, as well as a slight-of-hand, component. I first came across this trick in one of Martin Gardner’s many books on recreational mathematics. I liked it so much that I have been stumping students, friends, and family members with it ever since. In order to make this trick work, you will need to practice it by yourself until the moves (illustrated at bottom) become automatic, before trying it out on someone else. Neuroscience For Kids The smell of a flower - The memory of a walk in the park - The pain of stepping on a nail.

Interactive Mathematics Miscellany and Puzzles Since May 6, 1997You are visitor number E66B7E in base 20 Raymond Smullyan, a Mathematician, Philosopher and author of several outstanding books of logical puzzles, tells, in one of his books, a revealing story. A friend invited him for dinner. He told Smullyan that his teenage son was crazy about Smullyan's books and could not wait to meet him.

60 Ways RAND Has Made a Difference In 2008, the RAND Corporation celebrated its 60th anniversary. The difference between RAND today and the organization that was created in 1948 is substantial and dramatic. Most notably, we started with one client — the U.S. Air Force.

The blood-brain barrier in a live zebrafish embryo Dr. Jennifer Peters’ and Dr. Michael Taylor’s winning image of the blood-brain barrier in a live zebrafish embryo perfectly demonstrates the intersection of art and science that drives the Nikon Small World Competition. The blood-brain barrier plays a critical role in neurological function and disease. Drs.

Jim Reed's Home Page (Interactive Activities) Web Resources Design: The high school mathematics resources created over the last two years have a different design. The dynamic interactive activities typically have a visual and symbolic output with a means to change length/parameters. For the units completed, I have tried to develop a comprehensive, concise set of math notes with applets that the reader to understand/remember the concepts and enhance their math intuition for real life applications. For most of these resources I want the user to start exploring the applet to discover as much of the pattern themselves, then use the notes on the left to fill in the rest of the pattern. I am using my own invention, CET (Closed Eyes Test) to check the effectiveness of the resources. If the resource passes CET, I can still see/interact with the applet with my eyes closed.

<Advanced Lab Teaching Resources> This page provides a map to our online teaching resources for advanced laboratories at Haverford College Physics. We have three labs that effectively fall in this category. Most unusally, our sophomore-level labs cover much of the material usually taught in Jr. lab. Our majors then take a semester of upper-level junior or senior level advanded lab. The sophomore labs have standard writeups (see below), while our advanced electronics and computer instrumentation lab is taught out of prerelease copies of the new version of Art of Electronics Lab Manual (courtesy of Tom Hayes, Harvard University), and our advanced lab course per se is project based and students do not have writeups to work off of.

Surprises in steel: The mystery behind Detroit entrepreneur's revolutionary Flash Bainite A Detroit entrepreneur surprised academics when he invented a heat-treatment that makes steel 7 percent stronger than any steel on record – in less than 10 seconds. That steel, now trademarked as Flash Bainite, has tested stronger and more shock-absorbing than the most common titanium alloys used by industry. Now Gary Cola is helping researchers at Ohio State University to better understand the science behind the new treatment, called flash processing. What they've discovered may hold the key to making cars and military vehicles lighter, stronger, and more fuel-efficient.
