Solar Storms

Photo: Solar Storm Causes X-Ray Aurora, On April 7, the SOHO spacecraft spotted a Solar Storm ejecting a cloud of energetic particles toward planet Earth. The plasma cloud’s center missed Earth, but high energy particles swept up by Earth’s magnetosphere still created a geomagnetic storm! Read more, from NASA.

Stronger Solar Storms Predicted; Blackouts May Result, John Roach for National Geographic News

“This prediction of an active solar cycle suggests we are potentially looking at more communication and navigation disruptions, more satellite failures, possible disruption of electric grids and blackouts, more dangerous conditions for astronauts—all these things,” Behnke said during the briefing.

Engineering Education Worldwide

Quality vs. Quantity in Engineering

This article discusses the Duke study (USA Under-counting Engineering Graduates) proposing an adjustment to the numbers used for comparing engineering education results of the United States, China and India.

Like Wadhwa, Johnson suggested that the recent emphasis on increasing the number of engineers in America should take a back seat to promoting quality. “The fact there may be X, Y or Z number of [science and engineering graduates] floating around, doesn’t necessarily speak to the question of does that represent the actual high level high skill innovative talent American industries are looking for,” he said.

Drinking Soda and Obesity

Scientists in food fight over soda (bozos at CNN deleted the webpage):

Biologically, the calories from sugar-sweetened beverages are fundamentally different in the body than those from food.

The main sweetener in soda — high-fructose corn syrup — can increase fats in the blood called triglycerides, which raises the risk of heart problems, diabetes and other health woes.

This sweetener also doesn’t spur production of insulin to make the body “process” calories, nor does it spur leptin, a substance that tamps down appetite, as other carbohydrates do, explained Dr. George Bray of the Pennington Biomedical Research Center in Baton Rouge, Louisiana.

“There’s a lack of fullness or satiety. The brain just seems to add it on,” said Dr. Louis Aronne, a Weill-Cornell Medical College doctor who is president of the Obesity Society.

As with so much life science the “answers” are not clear (Medical Study Results Questioned – Why Most Published Research Findings Are False). The article presents arguments from those who disagree about the link between drinking soda and the dramatic rise in obesity in the USA.

K-12 Engineering Education Grant for Purdue

Bechtel $1 million grant for k-12 engineering education programs at Purdue

The $1 million grant from Stephen D. Bechtel Jr is renewable for up to four additional years and will expand Purdue university’s educational research efforts to foster an interest in science and engineering in K-12 classrooms.

The grant will support research and program development in Purdue’s Department of Engineering Education.
Earlier the department received $1 million grant from the National Science Foundation to launch the Multidisciplinary Engineering program.

Engineers Discuss: Is America Falling Behind?

Is America Falling Behind? Engineers Discuss Ways to Stem the Brain Drain by Chriss Swaney, Carnegie Mellon Today

“We still lead the world in research and development,” Carnegie Mellon University Engineering Dean Pradeep Khosla, said. “We can make the changes necessary to be competitive.”

“We must train engineers who will be managing, creating and deploying innovation.” – Khosla

Math, Science and Engineering Scholarships Proposal

Angelides pledges math, science, engineering scholarships

Democratic gubernatorial primary candidate Phil Angelides told Silicon Valley business executives Thursday he could reduce Silicon Valley’s dependency on skilled foreign workers by offering thousands of college scholarships to California students who study science, math and engineering.

If he were governor, Angelides told business executives, the California Tomorrow Fellowship program would award 10,000 students with up to $10,000 each for college expenses.

The state, he said, would put up $50 million and the remaining $50 million, he hopes, would be matched by businesses, universities and foundations.

“Last year California graduated 6,700 young people with degrees in engineering. South Korea, a country barely a third larger” than California, “graduated 56,000,” Angelides told a gathering of the Silicon Valley Leadership Group.

$20 Million for Georgia Tech School of Industrial and Systems Engineering

Georgia Tech School of Industrial and Systems Engineering Receives $20 Million Commitment

Georgia Tech’s School of Industrial and Systems Engineering (ISyE), ranked No. 1 in the country for the past 15 years by U.S. News & World Report, has received a commitment of $20 million from Georgia Tech alumnus H. Milton “Milt” Stewart and his wife, Carolyn Stewart.

The commitment establishes a permanent endowment, the income from which will be available for unrestricted use within ISyE.

Proposed Legislation on Science and Education

“Protecting America’s Competitive Edge” Legislation Proposal

Proposals include:

Each year, up to 10,000 bright students would receive a 4-year scholarship to earn a bachelor’s degree in science, engineering or math, while concurrently earning teacher certification. In exchange for these scholarships, they would be expected to serve for at least four years as a math or science teacher.
Each year, up to 25,000 bright young Americans would receive a 4-year competitive scholarship to earn a bachelor’s degree in science, engineering or math, so that our brightest students pursue studies in these fields which are so critical to our economic growth. Up to 5,000 students who have already earned their bachelor’s degree, would compete to receive graduate research fellowships to cover education costs and provide a stipend.

Better Way To Desalinate Water

NJIT Professor Discovers Better Way To Desalinate Water – NJIT broke the link to their press release so I removed it 🙁 A university breaking news release web link, sigh. At least far fewer web sites are run by pointy haired bosses that don’t understand extremely basic rules like web pages must live forever.

Chemical engineer Kamalesh Sirkar, PhD, a distinguished professor at New Jersey Institute of Technology (NJIT) and an expert in membrane separation technology, is leading a team of researchers to develop a breakthrough method to desalinate water. Sirkar, who holds more than 20 patents in the field of membrane separation, said that using his technology, engineers will be able to recover water from brines with the highest salt concentrations.

Leonardo da Vinci

Leonardo da Vinci drawings including a larger version of the image above.

Math and the Mona Lisa : The Art and Science of Leonardo da Vinci is an excellent book exploring the visionary science of Leonardo da Vinci. More excellent science books that we recommend.

An excellent site for learning more about Leonardo – Museum of Science Leonardo web site (includes classroom activities):

Leonardo da Vinci may seem an unusual topic to study in science. But the more you learn about this remarkable Renaissance man, the more you will realize that he was a terrific role model for applying the scientific method creatively in every aspect of life including art and music. Although he is best known for his dramatic and expressive artwork, Leonardo also conducted dozens of carefully thought out experiments and created futuristic inventions in a time before modern science and invention had really begun.
