HARDIN VALLEY—It was a once-in-a lifetime opportunity for some, a chance to shake hands with the president of the United States of America or wave at his heavily guarded motorcade as it passed by on a local roadway.

For others, it was a chance to hear about a presidential proposal modeled after a Tennessee program that would make the first two years of community college free to students who maintain at least a 2.5 grade point average. That proposal, officially announced at Pellissippi State Community College in Hardin Valley on Friday, expands on the 20th century idea that all children in the United States are entitled to a public education. In the 21st century economy, the White House said, 12 years of school is no longer enough.

For a much-smaller group, Friday’s visit by President Barack Obama, Vice President Joe Biden, and his wife Jill Biden offered an opportunity to hear an in-person announcement of a new advanced manufacturing hub, the country’s fifth, that will be led by the University of Tennessee in Knoxville and have Oak Ridge National Laboratory as a founding partner. That announcement at Techmer PM in Clinton was highlighted by a 3-D printed carbon fiber replica of a Shelby Cobra that the president joked about receiving for his birthday. [Read more…]

Guest column: ‘A Day of Publick Thanksgiving and Prayer’

In October of 1789, George Washington issued a proclamation “recommending” to the people of the United States a day of “Publick Thanksgiving and Prayer.” He urged Americans to remember “with grateful hearts the many and signal favors of Almighty God.” He published this proclamation, less than a month after the Constitution was signed, at the request of Congress.

Seventy-four years later, in the midst of a bloody and bitter civil war, a different president issued another Thanksgiving Day proclamation. In his proclamation, Lincoln called for “a day of Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens.” He urged Americans to acknowledge “the gracious gifts of the Most High God, who, while dealing with us in anger for our sins, hath nevertheless remembered mercy.”

School children of my generation were assigned to read and study such Thanksgiving proclamations from our presidents. But today, it seems school children are seldom required to become familiar with such historic proclamations. Why is this? Are our schools, and popular culture in our nation, conspiring to obscure the meaning of Thanksgiving? [Read more…]

For the fourth consecutive time, Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, has retained its position as the world’s number one system. Meanwhile, Titan at Oak Ridge National Laboratory, which was the top supercomputer in November 2012, remains number two.

Tianhe-2 is capable of performing at 33.86 petaflops, or 33.86 quadrillions of calculations per second, on a benchmark test known as Linpack.

The rankings are from the 44th edition of the twice-yearly TOP500 list of the world’s most powerful supercomputers, which was announced Monday in Mannheim, Germany; Berkeley, California; and Knoxville. Tianhe-2 has been in the top spot four consecutive times, and Titan has been number two each time. [Read more…]

A Chinese supercomputer kept its No. 1 spot, and Titan at Oak Ridge National Laboratory stayed at No. 2 in the latest semiannual ranking of the world’s most powerful supercomputers.

The Chinese supercomputer, Tianhe-2, was developed by China’s National University of Defense Technology, and it’s been in the top spot three times in a row on the Top500 List. Tianhe-2 bumped Titan from the top spot in June 2013.

The Chinese supercomputer performed at 33.86 petaflops—that’s 33.86 quadrillion calculations per second—on a test known as the Linpack benchmark, the press release said. Titan performed at 17.59 petaflops.

There was little change among the ranking of the world’s Top 10 supercomputers in the latest edition of the closely watched list, a press release said. The only new entry was at number 10—a 3.14-petaflop Cray XC30 installed at an undisclosed U.S. government site.

The Top500 list was announced Monday morning. The list is compiled by Erich Strohmaier and Horst Simon of Lawrence Berkeley National Laboratory, Jack Dongarra of the University of Tennessee in Knoxville, and Martin Meuer of Prometeus, Germany. [Read more…]

ORAU: Nearly 2/3 of foreign doctorates staying in U.S. 10 years after graduation

ORISE report suggests foreign doctorate recipients routinely take regular employment in the U.S. after completing postdoctoral appointments

The number of foreign, science, and engineering doctorate students who remain in the United States after graduation has declined slightly during the past five to 10 years, but long-term stay rates indicate that nearly two-thirds of foreign doctorates are continuing to stay in the U.S. These are the latest findings in a series of biennial reports that have been produced by the Oak Ridge Institute for Science Education and funded by the National Science Foundation since 2000.

The latest report is titled “Stay Rates of Foreign Doctorate Recipients from U.S. Universities, 2011.” It documents a study in which 2011 tax records—the most recent data currently available for the study—were used to estimate the proportion of foreign doctorate recipients from U.S. universities who stayed in the U.S. after graduation for any reason. The “Survey of Earned Doctorates,” published annually by the NSF, collects information from each graduate school on people completing doctorates each year. The Social Security Administration then calculates the proportion of those graduates with annual earnings of $5,500 or more, and these tabulations are used with appropriate adjustments (e.g., death) to produce the stay rate.

The 2011 stay rate for all foreign doctorate recipients, including those on permanent visas at graduation, was 68 percent for those graduating five years earlier, and 65 percent for those graduating 10 years earlier. [Read more…]

Professor also ORNL researcher, co-author of Top 500 ranking of the world’s most powerful supercomputers

KNOXVILLE—The U.S. Department of Energy recently released a report co-chaired by Jack Dongarra, a distinguished professor at the University of Tennessee in Knoxville, in which he stresses the importance of prioritizing research into high-end mathematics to help keep the United States on the cutting edge of computing.

“Exascale computing (capable of one quintillion floating point operations per second) will enable us to solve problems in ways that are not feasible today and will result in significant scientific breakthroughs,” said Dongarra, of UT’s Department of Electrical Engineering and Computer Science. “However, the transition to exascale poses numerous scientific and technological challenges.”

Dongarra, one of five National Academy of Engineering members on the faculty of UT’s College of Engineering, said that increased funding for the development of new models and ways of gathering data is key to unlocking a number of those challenges. [Read more…]

U.S. Sen. Bob Corker has called on the Obama administration to maintain its commitment to nuclear modernization in next year’s budget and include the necessary funding in the fiscal year that starts in October.

Corker, a Tennessee Republican, made the request after Defense Secretary Chuck Hagel expressed support for resources to modernize the nation’s nuclear arsenal.

Corker is the ranking member of the Senate’s Foreign Relations Committee.

In a press release, he said President Barack Obama agreed to provide the “full and necessary funding to upgrade and modernize the United States’ aging nuclear arsenal” during the Senate debate in 2010 over the New START Treaty with Russia. [Read more…]

Final milestone in U.S.-Russian partnership converting nuclear warheads into fuel

WASHINGTON, D.C.—Russia has converted 500 metric tons of highly enriched uranium—the equivalent of 20,000 nuclear warheads—and the resulting low enriched uranium, or LEU, has been delivered to the United States, fabricated into nuclear fuel, and used in nuclear power plants to generate nearly 10 percent of all U.S. electricity for the past 15 years, federal officials said.

That’s roughly half of all commercial nuclear energy produced domestically during that period, a U.S. Department of Energy press release said.

Energy Secretary Ernest Moniz announced the final LEU shipment on Thursday.

The LEU was derived from Russian weapons-origin highly enriched uranium, or HEU, under the 1993 U.S.-Russia HEU Purchase Agreement, commonly known as the Megatons to Megawatts Program, the press release said. [Read more…]
