The Elegant Universe: Pt 1

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.

The Planet's Most Powerful Digital Camera Captures Its First Images of the Universe - Megan Garber The device could help astronomers figure out why the expansion of the universe is accelerating. Zoomed-in image from the Dark Energy Camera of the center of the globular star cluster 47 Tucanae, which lies about 17,000 light years from Earth (Dark Energy Survey Collaboration) The Dark Energy Camera is the world's most powerful digital camera. About the size of a phone booth and boasting 570 megapixels, the device took eight years to construct -- by astronomers, technicians, and engineers collaborating across three continents -- and is currently mounted to the Blanco telescope in Chile.

Practical Physics This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science. Practical activities are not just motivational and fun: they can also sharpen students’ powers of observation, stimulate questions, and help develop new understanding and vocabulary. The Visible Universe, Then and Now Before the telescope was invented in 1608, our picture of the universe consisted of six planets, our moon, the sun and any stars we could see in the Milky Way galaxy. But as our light-gathering capabilities have grown, so too have the boundaries of the visible universe. Our interactive map shows how the known universe has grown from 1950 to 2011.

The Universe is Alive “Night, when words fade and things come alive. When the destructive analysis of day is done, and all that is truly important becomes whole and sound again.” -Antoine de Saint-Exupery When you look out into the Universe, what is it that you typically think of? Do you think of reliable, fixed stars and constellations? 100 Best (Free) Science Documentaries Online No matter how much you know, there is always something new to learn about science. While your college courses may cover the basics, you can get a more in-depth look at a wide variety of topics from Internet resources such as these great documentaries. These selections will help you explore everything from the inner reaches of the human mind to the outer areas of our universe and just about everything else in between. Better yet, they’re all free to watch online so you can learn more without spending a dime.

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. Birth of the Moon Posted by admin on Saturday, February 11, 2012 · The latest episode of Cosmic Journeys, enjoy in full HD 1080p. Scientists have been reconstructing the history of the moon by scouring its surface, mapping its mountains and craters, and probing its interior. What are they learning about our own planet’s beginnings? Decades ago, we sent astronauts to the moon as a symbol of confidence in the face of the great cold war struggle. The Scale of the Universe Interactive Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2012 March 12 The Scale of the Universe - Interactive Flash Animation Credit & Copyright: Cary & Michael Huang Explanation: What does the universe look like on small scales?

NASA finds extra-terrestrial amino-acids in Sudan meteorites Earlier this month, NASA announced the discovery of bacteria living in arsenic in a California lake. Now they have uncovered ET amino-acids in meteorite fragments that landed in northern Sudan. The meteorite was a fragment of a parent asteroid measuring 13-feet-wide (4m), and weighing 59-tons. The Secret to Productivity: Focus Technology has helped us do so much more, so much faster. But many experts argue that work-related systems and tools haven’t necessarily made us more productive. How many times does your phone, tablet or computer chime to indicate email or a Facebook notification? The reality is that while technology has the ability to improve productivity, too many people allow it to distract. Ultimately, the key to getting more done in less time requires focus.

Breakthrough Nanotechnology Will Bring 100 Terabyte 3.5-inch Digital Data Storage Disks Have you ever dream of 100 terabyte of data per 3.5-inch disk? New patented innovation nanotechnology from Michael E. Thomas, president of Colossal Storage Corporation, makes it real. Exoplanets An interactive version of XKCD 1071: Exoplanets using data from Planetary Habilitability Laboratory (via @ProfAbelMendez) and adapted code from the d3.js Bubble Chart example (by @mbostock). Planets are drawn to scale using radius data. The dataset also includes attributes such as atmosphere type, which is included in the information area on the left. The dataset is large (about 1.1mb), so it may take a few seconds to load. All blue and light brown planets are smaller than Jupiter.
