Remembering The Man Who Made Jet Fighters Possible

Richard T. Whitcomb solved a problem that had bedeviled aviation engineers, leading to supersonic flight. He died Tuesday at age 88. NASA

He Sparked Supersonic Flight With A Coke Bottle And File -- Wall Street Journal

Richard T. Whitcomb dreamed up techniques that made supersonic flight possible and innovations that endure on passenger jets today.

Mr. Whitcomb, who died Oct. 13 at age 88, solved a problem that had bedeviled aviation engineers, whose designs couldn't achieve supersonic flight even though they seemed to have enough power. Increased wind resistance at speeds approaching the speed of sound was the problem. Engineers took to calling it the "sound barrier."

Rocking On With Hot Rocks Geothermal Energy

From NOVA:

The world is getting hotter. This is because of the increasing concentration of greenhouse gases in the atmosphere, due mainly to our excessive burning of fossil fuels. We burn them for the energy that is needed increasingly in our daily life – to drive to school, cool ourselves on hot summer days, blow-dry our hair and listen to our music. The resulting greenhouse gases trap radiation from the sun, preventing it from escaping back into space, causing the planet’s temperature to rise. But not all of the planet’s heat comes from the Sun; some of it is within the Earth; and rather than causing global warming it could help to wean us off fossil fuels.

This heat, geothermal energy, lies in abundance beneath our feet. If the energy stored in hot rocks inside the Earth could be tapped and used instead of fossil fuels, it could help to reduce the threat of climate change.

Marine Plant Life Holds The Secret To Preventing Global Warming

Mangrove forests, salt marshes and seagrass beds, above, cover less than 1 per cent of the world's seabed, but lock away well over half of all carbon to be buried in the ocean floor

From Times Online:

Life in the ocean has the potential to help to prevent global warming, according to a report published today.

Marine plant life sucks 2 billion tonnes of carbon dioxide from the atmosphere every year, but most of the plankton responsible never reaches the seabed to become a permanent carbon store.

Mangrove forests, salt marshes and seagrass beds are a different matter. Although together they cover less than 1 per cent of the world’s seabed, they lock away well over half of all carbon to be buried in the ocean floor. They are estimated to store 1,650 million tonnes of carbon dioxide every year — nearly half of global transport emissions — making them one of the most intense carbon sinks on Earth.

Bizarre Galaxy Is Result Of Pair Of Spiral Galaxies Smashing Together

Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the centre of the other, until ultimately, the two merge into one massive galaxy. NGC 2623 is in the late stages of the merging process, with the centres of the original galaxy pair now merged into one nucleus, but stretching out from the centre are two tidal tails of young stars, a strong indicator that a merger has taken place. During such a collision, the dramatic exchange of mass and gases initiates star formation, seen here in both the tails. (Credit: NASA, ESA and A.
