The Unbelievable Accuracy of the Monte Carlo Method

Stanislaw Ulam

Published on Jan 18, 2013

The year was 1945, the year I was born. That in itself is of great significance to me.  However, it was a momentous year in history. World War II came to its merciful end and the development of the first electronic computer – the ENIAC—was nearing completion. At a post-war Los Alamos National Laboratory (LANL), mathematician Stanislaw Ulam envisioned the possibilities of reviving statistical techniques that would have a huge impact on science and technology research today. (Read the history of Stanislaw Ulam in the special edition of Los Alamos Science No. 15, 1987.)

Science and a Movie

Published on Sep 18, 2012

DOE’s ScienceCinema is now showing “A LANL Scientist’s Dream Takes Off to Zap Rocks on Mars” starring Roger Wiens.

At age 9, Roger Wiens and his brother built rockets, a whole fleet of rockets. They also built a telescope that allowed them to draw craters they saw on Mars when  it neared close to earth. Little did Roger know that he would be putting a camera on Mars 40 years later. Roger Wiens is now a LANL planetary scientist and the principal investigator of the Mars Science Laboratory mission’s ChemCam team. The ChemCam instrument fires a laser at Martian rocks and looks at the resultant flash to determine the composition. Data obtained from Chemcam is helping to answer the question of about life on Mars. Visit DOE’s ScienceCinema to catch Roger’s excitement along with a team of 40 people at the Los Alamos National Laboratory (LANL) and the collabortaion of the French Space Agency IRAP as the Curiosity rover reaches Mars.

University of Tennessee Knoxville in DOE’s .EDUconnections Spotlight

University of Tennessee Knoxville

Published on Sep 04, 2012

Science is always in the spotlight at the University of Tennessee Knoxville, a land-grant institution and the state's flagship research campus.  Recent research might include searching for potential habitats for life on Mars, developing an autotaxin  inhibitor to fight cancer, designing a car for the DOE EcoCAR 2 competition, determining  the boundaries of the nuclear chart or developing “Living Light”, a net-zero energy home for DOE’s Solar Decathlon. UTK is situated in an ideal environment for research.

Wind Turbines and Wear and Tear

Wind turbine electrical power generation facility

Published on Aug 20, 2012

A modern wind turbine has more than 8,000 component parts that must withstand the wear and tear of wind stresses. DOE researchers and stakeholders have been working hard to predict and eliminate wind stress related barriers and extend the lifespan of wind turbines.  Working on a paper on this subject? OSTI can save you wear and tear by providing web tools that eliminate the need to search through database after database to find the research you need.  For example, if you use DOE’s Science Accelerator, you could search through 11 DOE databases, and in about 10 seconds or less, retrieve hundreds of documents about the use of simulations to understand wind turbine shear stress

Published on Aug 06, 2012

New simulation tools and data collection capabilities now available for wind power research are creating a lot of excitement and significant advances in the wind energy industry. For example, DOE’s National Renewable Energy Laboratory (NREL) tripled previous estimates of U.S. wind power potential by using advanced wind mapping and validation techniques. New wind development areas were also identified where the wind resource was previously considered unsuitable.

Published on Jul 16, 2012

  In the world of nanomanufacturing, new materials, devices, components and products are emerging at a breathtaking rate. Next-generation nanocoatings are being developed to enhance wear resistance of industrial materials.  An infrared retina that includes adaptive sensors has been patented. Self-cleaning skin-like prosthetic polymer surfaces have been developed at Oak Ridge National Laboratory (ORNL). ORNL is also well on its way to creating nano catalysts for diesel engine emission remediation
