Black hole had 18th century feeding frenzy

About 300 years ago, the black hole lurking in the heart of the Milky Way woke from hibernation and entered a feeding frenzy, triggering a cascade of x-rays that reverberated off nearby clouds, researchers say.

The energy released by the event was so intense that echoes remain etched in an interstellar cloud today.

The findings, reported by Japanese astronomers, may explain why our galaxy's black hole, known as Sagittarius A*, is so laid-back compared to similarly sized monsters in other galaxies.

"Perhaps it's just resting after a major outburst," says Kyoto University's Tatsuya Inui, lead author of a paper in the Publications of the Astronomical Society of Japan.

Data taken between 1994 and 2005 revealed a quick-lived but intense flash of x-rays from a large cloud known as Sagittarius B2, which lies 300 light-years from the Milky Way's black hole.

Scientists believe the black hole's frenzy spewed out x-rays that blasted electrons off iron molecules in the cloud.

It should take you two and a half seconds to read this sentence. Any faster and you won't absorb its meaning. The motor response of the retina, and the time it takes the image of a word to travel from the macula to the thalamus to the visual cortex for processing, limits the eye to about 500 words a minute. (That's peak efficiency; the average college student can expect a rate about half that.) "There is no such thing as speed reading," says Keith Rayner a cognitive psychologist at the University of Massachusetts-Amherst. "Not if your definition of reading is comprehending text." Studies show that fast readers fare worse than slower ones when questioned about the text. So, to get smarter, slow down. It's even OK to move your lips.

clipper's remarks: The site has the contents and articles from the magazine. For some reason it reminds me a bit of Clipmarks! In any case, I am sure there is a wealth of information there to be shared.

The Penny Magazine, published every Saturday, was aimed at the working class. It was part of the Society for the Diffusion of Useful Knowledge's program for liberal reform. for its reader, however, it was a source of information on subjects of general interest: everyday things like tea and coffee, well-known places in England, a series on animals and birds of Britain, descriptions of prsent-day manufacturing, even an American alaman and a serial of a personal account of an immigrant's problems. Poetry was published, too, and there are several illustrations in each issue.

clipper's remarks: "The United States, some years back, found its new bogeyman "Islam" to replace its former imaginary enemy "Communism." And now the European press appears to have finally (?) found a replacement for the Jewish people that they used to malign and attack. Anti-Islam/Muslimism appears to now have officially replaced anti-Jewish sentiments in Europe.

The roots of these attacks are the same: an inability to acknowledge and respect a diversity of people that might result in a Europe that is non-White and/or non-Christian.

The anti-Muslim/Islam cartoons of today are little different than the anti-Jewish cartoons that were published by the Nazis during WW II."
