Can a Genetic Disease Be Cured? The Scale of the Universe - StumbleUpon. NOVA. Why Did NASA Kill Cassini? On September 15, 2017 NASA destroyed Cassini—on purpose. Why kill a multibillion-dollar spacecraft? Sep 20, 2017 Death Dive to Saturn Follow Cassini's final days as it skims the cloud tops before plunging into the planet. Commentary: Unsolicited and Unwelcome, Climate Denial Comes to Schools In mid-March of 2017, I saw the first indications of trouble. From Education Blog | Sep 19, 2017 Cassini's Search For Life Is there life beyond Earth?
Sep 15, 2017 Amazing Discoveries from Cassini Relive Cassini's greatest hits from its 13 years studying Saturn. 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.

The blood-brain barrier in a live zebrafish embryo | 2012 Photomicrography Competition. 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. Peters and Taylor, developed a transgenic zebrafish to visualize the development of this structure in a live specimen. To achieve this image, Peters and Taylor used a maximum intensity projection of a series of images acquired in the z plane. Both Peters and Taylor have more than ten years of imaging experience. 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. 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. Over the past six decades, we've enjoyed productive relationships with thousands of clients. The mix of studies, singular accomplishments, and streams of research and analysis included in this book exemplifies the range and originality of RAND research.
RAND's 60 years have been distinguished by an impressive number of prominent, even famous, experts in various fields, including winners of the Nobel Prize in several disciplines. Major breakthroughs usually cannot be seen as such until so much history has passed that lots of other people have long since taken or been given credit. In the early days of RAND, much of our research was not widely available. In assembling this collection, we have enjoyed reflecting on various aspects of our legacy. Michael D. 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] 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.
All non-immediate knowledge of the world is based on these premises, which are unprovable assumptions, or axioms. Axioms by Robert G. Dedication Notice Copyright Notice. Rader's NUMBERNUT.COM.

Teachers | STEM Education Resource Center. Welcome to PBS Teachers STEM Education Resource Center! Science, Technology, Engineering and Math (STEM) Resources for Grades PreK-12 PBS offers all Americans the opportunity to explore new ideas and new worlds related to science, technology, engineering, and mathematics (STEM) learning through television and online content.
On-line broadband access and digital media are dramatically changing the opportunities available to the nation’s educators improving STEM education. Our recent national educator survey (Grunwald, 2009) indicates that more teachers than ever before are turning to digital media resources to help their students understand concepts, practice new skills and engage in exciting, authentic learning experiences. Explore some of our great STEM offerings for grades PreK-12.

National Center for Case Study Teaching in Science (NCCSTS) Neuroscience For Kids. The smell of a flower - The memory of a walk in the park - The pain of stepping on a nail. These experiences are made possible by the 3 pounds of tissue in our heads...the BRAIN!! Neuroscience for Kids has been created for all students and teachers who would like to learn about the nervous system. Discover the exciting world of the brain, spinal cord, neurons and the senses. Use the experiments, activities and games to help you learn about the nervous system. There are plenty of links to other web sites for you to explore. Can't find what you are looking for?

Portions of Neuroscience for Kids are available in Spanish, Slovene, Portuguese, Italian, Korean, Japanese, Serbian, Russian, Slovak, Romanian, Polish, Albanian, Czech, Finnish, Estonian, Hungarian, Punjabi, Indonesian, Malay, Norwegian, Ukranian and Turkish. "Neuroscience for Kids" is maintained by Eric H. <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.
Feel free to contact us with any questions. 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. The Physics Classroom.
