The method most commonly used - loading from the back to the front - is, as you might expect, the most inefficient. But using computer simulations, Jason Steffen, an astrophysicist who works at the Fermi National Laboratory outside of Chicago, has come up with a new method that's much improved. It involves loading one side of the plane at a time, filling first the window seats, then the middle seats, and finally the aisle seats. Dr. Steffen's method is a variation of an earlier studied method known as the Wilma method, but nearly doubles the boarding speed. Steffen's results appear in the Journal of Air Transport Management. You can also read more about it on the BBC website.
Courtesy US White HouseA concept for a plane that could make the trip from New York City to London in 90 minutes (a trip that ranks somewhere between going to the grocery store and going to the bathroom for me, in terms of frequency) was just unveiled at the Paris Air Show. It uses standard jet engines, along with rockets and ramjets. Also, it will use jet fuel made from algae. Pretty sweet.
Unfortunately, while it only takes an hour and a half to cross the Atlantic, it will take 40 years to arrive in reality. If it ever does. We'll probably all be riding pegasuses (or octopi) at that point anyway, so supersonic jets will seem lame.
Last night, Louisiana Governor Bobby Jindal criticized government spending authorized by the stimulus bill, calling particular attention to "something called volcano monitoring." Hey, $140 million is a lot of money, and what does it get us? Turns out volcano monitoring is actually kind of a big deal.
It teaches us a lot about earth processes, of course, but some folks aren't swayed by talk of scientific advancement.
An argument for everyone is that monitoring enables authorities to plan and implement evacuations when necessary.
"The USGS has issued several warnings over the past 10 years, though predicting the timing and size of eruptions remains a difficult task.
Volcano monitoring likely saved many lives — and significant money — in the case of the 1991 eruption of Mount Pinatubo in the Philippines (where the United States had military bases at the time), according to the USGS.
The cataclysmic eruption lasted more than 10 hours and sent a cloud of ash as high as 22 miles into the air that grew to more than 300 miles across.
The USGS spent less than $1.5 million monitoring the volcano and was able to warn of the impending eruption, which allowed authorities to evacuate residents, as well as aircraft and other equipment from U.S. bases there.
The USGS estimates that the efforts saved thousands of lives and prevented property losses of at least $250 million (considered a conservative figure)."
Still not convinced? Here's another benefit: volcano monitoring keeps our air routes safer, too. See, a pilot can't easily tell the difference between an ash cloud and a regular cloud. But ash clouds can damage flight control systems and kill jet engines. Don't think that's really a big problem? Some 10,000 passengers and millions of dollars' worth of cargo are ferried by US aircraft over the North Pacific every day, and there are 100 potentially dangerous volcanoes under those air routes.
Suddenly "volcano monitoring" doesn't seem like a goofy piece of esoteric research...
