Faster than the speed of light? Or an anomaly?

Albert Einstein

 

According to Einstein's theory of relativity, it is not possible for matter to travel faster than the speed of light in a vacuum.  The speed of light (186,282 miles per second) has long been considered a cosmic speed limit, and much of modern physics is based on Einstein's work. Now there is a possibility that Einstein was wrong -- and physics may have to rethink the concept of matter and energy.


The science world was surprised when workers at CERN, the world's largest physics lab, recently announced that they had recorded subatomic particles travelling faster than the speed of light.  If their findings are proven to be correct, they would overturn one of the pillars of the Standard Model of physics, which attempts to explain the way the universe and everything within it works. 
Neutrinos have long been suspected of being able to travel beyond light speed but the ability to measure their speed accurately has only recently been possible thanks to the CERN lab. This may be one of those moments in science history that opens the door to new discoveries, and could change the way we understand the universe and ourselves. However, given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established.

Celebrate National Engineers’ Week 2011 – February 20-26, 2011

The celebration of National Engineers’ Week started in 1951 by the National Society of Professional Engineers.  The week occurs in February, in conjunction with President George Washington's Birthday; our first President is considered by many engineers to be the nation's first engineer because of his survey work.

 

Engineering has made countless contributions to enhancing modern life by making it more comfortable, safe and prosperous.  Engineers use imagination and analytical skills to invent, design, improve and build things. They turn ideas into reality, apply basic research and dream up creative and practical solutions.   Engineers change the world.

 

The engineering field is as varied as engineers themselves. Engineers design and build superstructures and delicate medical instruments.  They explore for energy and better and more efficient ways to deliver it, design environmental controls for buildings and are driving innovation in wind energy, fuel cell technology, solar energy, geothermal energy, petroleum, gas, nuclear engineering, alternative energy and energy efficiency to fusion, hydrogen and superconductor technologies.

 

Who knows where the next great challenges and breakthroughs will be?

 

At DOE and the National Laboratories engineers support the discovery and design of new materials with novel structures, functions and properties that may lead to new materials for the generation, storage and use of energy or address and solve environmental impacts of energy use. Other engineers use modern tools and capabilities in the engineering sciences to ensure the safety, security, reliability and performance of the current and future U.S. nuclear weapons stockpile without having to...

Celebrate National Chemistry Week 2010 – October 17-23

National Chemistry Week

 

Chemistry has made countless contributions to enhancing modern life by making it more comfortable, safe and prosperous.

Chemistry is a physical science that studies atoms, molecules, crystals and other aggregates of matter.  Understanding the basic properties of matter and learning how to predict and explain changes are what chemistry and chemists are all about.  Chemistry can be very specialized, dealing with the composition, behavior, structure and properties of matter, as well as changes that occur during chemical reactions.

 

The Chemical Sciences, Geosciences, and Energy Biosciences Division (CSGB) in the Department of Energy’s (DOE) Office of Science supports chemistry. CSGB is also involved in DOE’s exciting new Energy Frontier Research Centers and Innovation Hubs. DOE funds approximately 20% of fedderally-funded chemistry research and is the largest source of funding for chemical engineering, sponsoring 40% of all federally funded research in that field in 2007.  Over the years, 26 researchers associated with DOE have been awarded a Nobel Prize in Chemistry for their work.

Value of a Semantic Science Accelerator and Means of Constructing It

by Dr. William Watson 28 Jul, 2010 in Technology

OSTI's current services accelerate science through what is largely a kind of card file.  We point people to particular pieces of literature or data that meet certain search criteria.  From there, people can build on what those pieces of information tell them and achieve new discoveries and inventions. 

Some of what the users achieve involves combining the information they get with other knowledge of their own that isn't represented in databases.  This of course requires some thought from the users.  But other achievements could result entirely from information that the users retrieve through OSTI, with no additional input whatsoever--namely inferences made directly from that information alone.  Right now, such inferences still generally require user involvement.  But software programs designed and tested in the last several years can automate some inferences from text and data tables.  In biology and medicine, these programs have already turned up connections in the literature that could accelerate our understanding, and thus treatment, of some poorly-understood diseases.[1]  Among the most recent inferential programs is Semantic Medline[2], which displays conceptual interconnections across multiple search results in a single graph, thus showing the searcher how his query's terms relate to other concepts, some of which he may not already know. 

If it were permanently left to unaided human users to make these inferences themselves, very few would ever be made, since no user knows every fact mentioned in the entire science and technology literature.  Computers, on the other hand, can check large sets of literature for explicit links between concepts and infer chains of such links to reveal unsuspected relations in the physical world.  The text-analysis software currently...

Enormous STI Content Made Easily Searchable by OSTI

WorldWideScience.org Meeting

 

We have integrated about ten OSTI products dealing with technical reports, e-prints, patents, conference proceedings, project summaries, etc., so that they are all searchable via s single query.  The integrated product allows users to search without first having to decide which OSTI product is likely to have the content he/she seeks.  This product is ScienceAccelerator.gov.

We have integrated comparable offerings from about 14 other agencies so that all the virtually combined offerings can be searched via a single query.  Science.gov allows users to search without first having to decide which agency offers which content.  The DOE contribution to Science.gov is ScienceAccelerator.gov .

We have integrated comparable offerings from about 70 other countries so that all the offerings can be searched via a single query.  The US contribution to WorldWideScience.org is Science.gov.  WorldWideScience.org allows users to search without first having to decide which country offers which content.  The virtual collection is enormous, being comparable in size to science made searchable via Google.  Our tests suggest, however, that well over 90% of the content of WorldWideScience is non-Googelable.

Until June 11, 2010, the content accessible via WorldWideScience had English titles and other bibliographic information.  On June 11, 2010 WorldWideScience became multilingual. ...
