A Slower Speed of Light. Download the Spring 2013 Beta Release For WindowsFor MacFor Linux Download the Summer 2012 release For WindowsFor Mac A Slower Speed of Light is a first-person game prototype in which players navigate a 3D space while picking up orbs that reduce the speed of light in increments.
Custom-built, open-source relativistic graphics code allows the speed of light in the game to approach the player’s own maximum walking speed. Download our PowerPoint presentation about the relativistic effects in the game. 1,000,000,000,000 Frames/Second Photography - Ramesh Raskar. Relativistic Baseball. What would happen if you tried to hit a baseball pitched at 90% the speed of light?
- Ellen McManis Let’s set aside the question of how we got the baseball moving that fast. We'll suppose it's a normal pitch, except in the instant the pitcher releases the ball, it magically accelerates to 0.9c. From that point onward, everything proceeds according to normal physics.

Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2015 December 19 Star Streams and the Whale Galaxy Image Credit & Copyright: R Jay Gabany (Blackbird Observatory) Collaboration: David Martínez-Delgado (University of Heidelberg), et al. Explanation: NGC 4631 is a spiral galaxy found only 25 million light-years away, toward the well-trained northern constellation Canes Venatici. Seen ege-on, the galaxy is similar in size to the Milky Way. Tomorrow's picture: dark Earth, red sprite. LIFE A Journey Through Time. News Blog: Quantum weirdness wins again: Entanglement clocks in at 10,000+ times faster than light. No matter how many times researchers try, there's just no getting around the weirdness of quantum mechanics.
In the latest attempt, researchers at the University of Geneva in Switzerland tried to determine whether entanglement—the fact that measuring a property of one particle instantly determines the property of another—is actually transmitted by some wave-like signal that's fast but not infinitely fast. Their test involved a series of measurements on pairs of entangled photons (particles of light) that were generated in Geneva (satellite view at left) and then split apart by optical fiber to two villages 18 kilometers (11 miles) apart where the team had set up photon detectors.
(In 2007, researchers transmitted entangled light 144 kilometers between two of the Canary Islands.) State of the Nation. If possible, the first images in each set will be true-color, as you would see them with your own eyes.
Most images will either be true-color or monochrome (black and white), unless stated otherwise. Many images can be vastly enlarged by clicking on them and choosing a larger size from the Flickr page. Downloading them may allow even larger sizes. 8 Wonders of the Solar System, Made Interactive.

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. Good quality, appropriate physics experiments and investigations are the key to enhanced learning, and clarification and consolidation of theory. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5. Space Time Travel – Relativity Visualized.
The Speed of God : Uncertain Principles. Over in Twitter-land, Eric Weinstein is visiting the AMNH at the same time as a bunch of Orthodox Jews, and takes the opportunity for a little Q&A: Me: Excuse me, but how is the phylogenetic tree reconciled with Torah.Modern Orthodox Man: Lorentzian time dilation.
It’s a head hurter. This is an interesting attempt to square the six-day creation story with modern science, and raises one obvious question: How fast must God have been moving for the six days of creation to last 13.7 billion years? This is veering into Built on Facts territory, but the relevant formula is: For six days (5.18×105 seconds) to seem like 13.7 billion years (4.32×1018 seconds), the Lorentz factor γ would need to be 8.34×1012.

Paul A.M. Dirac - Biography. Paul Adrien Maurice Dirac was born on 8th August, 1902, at Bristol, England, his father being Swiss and his mother English. He was educated at the Merchant Venturer's Secondary School, Bristol, then went on to Bristol University. Here, he studied electrical engineering, obtaining the B.Sc. (Engineering) degree in 1921. He then studied mathematics for two years at Bristol University, later going on to St. John's College, Cambridge, as a research student in mathematics.

But in reality, water - the foundation of life and most common of liquid - is really weird and scientists actually don't completely understand how water works. Science News, Articles and Information. Atomic Structure Lessons : Chemistry Zone. Solar and Heliospheric Observatory Homepage. Evol_massive5.swf (application/x-shockwave-flash Object) Atomic Structure. An updated version of this lesson is available at Visionlearning: Atomic Theory & Ions & Isotopes In the last lesson we learned that atoms were particles of elements, substances that could not be broken down further.
In examining atomic structure though, we have to clarify this statement. An atom cannot be broken down further without changing the chemical nature of the substance. Fundamental Forces.
