Saying Goodbye to Cassini Cassini, a brave explorer that was dispatched to study a distant ringed world, has died. What Saturn Can Tell Us About Earth—and Beyond After Friday’s crash landing into Saturn, NASA scientists are reflecting on the lessons Cassini has imparted.
Welcome - The Richard Dawkins Foundation for Reason and Science axioms Contents Contents | rgb Home | Philosophy Home | Axioms | Other Books by rgb: | The Book of Lilith | Axioms is a work that explores the true nature of human knowledge, in particular the fundamental nature of deductive and inductive reasoning. It begins by embracing Hume's Skepticism and Descartes' one ``certain'' thing, and then looking for a way out of the solipsistic hell this leaves one in in terms of ``certain'' knowledge. Indeed, to the extent that philosophy in the past has sought to provide certain answers to virtually any question at all, philosophy itself proves to be bullshit - all philosophical arguments ultimately come back to at least one unprovable premise, usually unstated, and can be refuted by simply asserting ``I don't agree with your premises.'' The way out is to give up the idea of certain knowledge. Axioms by Robert G. Dedication No book is written in a vacuum. Notice Copyright Notice Copyright Robert G. Lulu Press www.lulu.com
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. In the current issue of Materials Science and Technology, the inventor and his Ohio State partners describe how rapidly heating and cooling steel sheets changes the microstructure inside the alloy to make it stronger and less brittle. "Steel is what we would call a 'mature technology.' Yet, when inventor Gary Cola initially approached him, Babu didn't know what to think. Cola's entire process took less than 10 seconds.
The Physics Classroom <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. Suzannne Amador Kane I also maintain a website with more information about medical physics-related labs. Sound Lab (intro level) We also have a related curriculum on science ethics that I will be posting shortly. AAPT listserv on advanced lab materials Lab Manual for Nanoscale Science and Technology (University of Wisconsin's MRSEC)--has excellent online materials with many good ideas. Physics 211: Laboratory in Electronics, Waves & Optics This course meets weekly for 3 hours per week. Physics 212: Quantum Physics Lab This course meets weekly for 3 hours per week. Physics 316: Advanced Electronics and Computer Instrumentation Physics 326: Advanced Physics Lab This is our project lab. Homeworks on error and data analysis

Rader's NUMBERNUT.COM 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. Notation[edit] Angles[edit] 1 full circle = 360 degrees = 2 radians = 400 grads. The following table shows the conversions for some common angles: Unless otherwise specified, all angles in this article are assumed to be in radians, but angles ending in a degree symbol (°) are in degrees. Trigonometric functions[edit] The primary trigonometric functions are the sine and cosine of an angle. The Sine of an angle is defined in the context of a Right Triangle, as the ratio of the length of the side that is opposite to the angle, divided by the length of the longest side of the triangle (the Hypotenuse ). Inverse functions[edit] and Related identities[edit]
