SGR 1806-20 is a "magnetar": a rapidly spinning neutron star that not only has an incredible density, trillions of times greater than ordinary matter, but an incredibly strong magnetic field.
On December 27, 2004, scientists detected the most powerful single burst of energy ever observed, aside from the Big Bang at the universe's first moment of existence.
It was from a special kind of star called a "magnetar".

Steam is wet right? Wrong. Drier than dust. Dry. Bone dry. But you can see the water in steam right? Wrong. Steam is invisible. Dry, invisible. When you "see" steam, you are actually seing the steam condensing to water droplets, or water vapour, which is indeed wet, and visible. Steam itself is dry because ALL the water has been turned into a gas- there is no liquid in steam. I found this to be a rather amazing fact when I first heard this, but I got a first hand demonstration of this when I recently built a reproduction windsor armchair, which requires some steam bending wood in a steam chamber. After steaming for over an hour in a steam chamber, the wood emerges DRY, really hot, and surpisingly pliable for about 30 seconds. :idea:

Hi Sean. The one I built is a reproduction "comb-back" windsor, based on an American design used in the 18 century, It was considered a colonial "lay-z-boy," if you will. I had never built one before, so it took a considerable long time. I used hand tools as much as practical, and hand shaved and tapered all the back rest spindles. I also turned all the legs, spindles, stretchers, ect out of solid maple on a lathe, the seat, in keeping with tradition, is carved out of pine, and the upper sections, arm rest, head rest, ect, is out of oak, which is a wood that lends itself well to steam bending. The legs enter the seat in a tapered hole, go right through the seat, then wedges are driven through to lock them in place. It was a really difficult project, I am by no means a very experienced wood worker, so all together it took three months, and about 80 hours to complete. I could build another one in less than half that, now that I know how to do it. If you are interested there are websites dedicated to chairmaking, and windsor chairmaking in particular. The piece is really beutiful, a bit gothic, and is very eyecatching in my home. Its comfy to sit in too. If you ever watch "the Patriot", with Mel Gibson, you will see windsor chairmaking in action right at the beginning of the movie. Let me know if you do decide to build one. :D
Thanks for the info.....i'll pass it along to my father who has always been into restoring old wood furniture.....but never building any....I think he is ready to take the plunge. He just finished with a rocking chair made by my wifes grandfather.....and has started on a wooden chest that has a brass plate on the bottom that reads Christmas 1842 or 49...something like that.

Where's the boof?
Try Minnesota.
Minneapolis St. Paul, to be more precise.
Since joining the Minnesota Twins pitching rotation earlier this season, Boof Bonser has appeared in six regular season games. The 25 year-old, right-handed starter has compiled a record to date of two wins against one loss, with an ERA of 4.68 over 32 and 2/3 innings.
Born John Paul Bonser, he legally changed his name to "Boof" in 2001.
It was his customary nickname from childhood.

Schematic of a single-celled organism with a rudimentary eye. http://www.biocab.org/Euglena_Class.html
In his 1995 book, River Out of Eden, and again in his 2004 Ancestor’s Tale, Richard Dawkins estimates that image-forming eyes have evolved anywhere from 40 to 60 different times [on earth], using a total of nine very different optical forms. It is striking how different the compound eyes of insects are from the single-lensed eyes of vertebrates, and how similar the camera like eyes of octopi and squid are to our own. Because photoreceptors reside on the inner side of the retina in those mollusks, yet on the outer side in vertebrates, we can be sure that such differences signal deeply independent [evolutionary] origins.
At least nine distinct design principles are evident in the total range of eyes: Pinhole eyes; two kinds of camera-lens eyes (vertebrate and octopus); curved reflector (“satellite dish”) eyes and several kinds of compound, multi-lensed eyes. Compound eyes have evolved independently in ostracods v. crablike crustaceans, as well as among annelid worm (sabellids), and bivalve mollusks. Camera-like eyes have evolved not only in vertebrates and octopuses, but independently in jumping spiders, some snails, alciopid polychaete worms, cubozoan jellyfish, and the backward looking eyes of coral reef shrimp.
Finally, while many single-celled protists have photosensitive eyespots, single-celled dinoflagellates have a lens in their eyespot!

Kinda reminds me of the conch I picked up snorkeling in Fiji. It was alive, and when I looked inside, I was startled to see 2 tiny bright blue eyes with black pupils looking back at me. They were so human-like, I had to put the little critter back where I got it.

I just saw the new two-hour National Geographic TV segment "Sky Monsters", on the topic of pterosaurs (winged dinosaurs).
If you've only imagined pterosaurs as rather primitive birds, more gliders than fliers, and able to get aloft only by taking advantage of rising currents of warm air, then you're in for a number of surprises ...
The computer generated animations are awesome in their apparent reality.

An enormous amoeba-like structure 200 million light-years wide and made up of galaxies and large bubbles of gas is the largest known object in the universe, scientists say.
The galaxies and gas bubbles, called Lyman alpha blobs, are aligned along three curvy filaments that formed about 2 billion years after the universe exploded into existence after the theoretical Big Bang. The filaments were recently seen using the Subaru and Keck telescopes on Mauna Kea ...

OD1: Always captialize GOD!
It's cool, Chip. That was me, quoting an old post from QDO1. Since he was not talking about God - the (Jewish or Christian) God - or any other specific god, but just about the general concept of (a) god, it's proper to use "god" in that context.
OK?
As for QDO1 - well, I haven't seen a post from him in months.

Around 37 AD, the Roman emperor Caligula - a madman of legendary depravity - commissioned two extraordinary ships for his exclusive use on the small and shallow freshwater lake called "Nemi" on the outskirts of Rome.
The ships were colossal, even by Roman standards. One was a floating temple to the Greek goddess Diana - or the Egyptian god Isis - archaeologists have entertained both theories about it. The other was a lavishly equipped floating palace, with a heated deck and baths, running water and other ornate and extravagant furnishings that would rival a cruise ship of today for comfort and luxury.
Decorative bronze from one of Caligula's ships.
http://www.utexas.edu/courses/romanc...ivimages12.htm
The priceless ships were scuttled when a palace revolt ended Caligula's brief reign and also his relatively brief life. And it was unprecedented extravagances like these ships that had drained the Roman treasury under Caligula and comprised part of the motivation for his violent overthrow.
The ships lay forgotten until 1446, when a first attempt was made to salvage artifacts. Other salvage attempts were made in 1535, 1827 and 1895, but no one had a workable plan to raise the sunken ships.
Enter the Fascist dictator Benito Mussolini, who rose to power in Italy after the first world war with dreams of restoring Italy as a modern reincarnation of the ancient Roman Empire. He had a cunning plan to retrieve the sunken ships. Instead of raising the ships, he would drain the lake - and he knew just how to do it. Long before Caligula's time, the Romans bored a mile-long tunnel through the adjacent hills - another amazing story - for drawing water from the lake. In 1929, Mussolini's regime installed powerful electric pumps and drained the entire lake, pumping the water out through the ancient Roman tunnel.
As archaeologists studied the remains of the ships, their astonishment grew with a series of unexpected discoveries. The ships featured corrosion resistant copper-clad nails, precision-built water pumps and precision water control valves cast in bronze, an unexpectedly modern anchor design and even what looked like modern ball bearings for a "magic" revolving statue, rotated by a mechanism hidden under its base - some 1400 years before the historical invention of ball bearings by Leonardo da Vinci.
The engineering and construction of the ships was a revelation that Roman technology, already regarded as unprecedented for its time, was even more advanced than anyone had previously realized.

http://www.abc.se/~pa/mar/nemships.htm
The ship remains and artifacts were housed in a purpose-built museum and teams of archaeologists continued to study them until the outbreak of the second world war.
Enter Adolf Hitler.
In 1944, retreating German soldiers, either at the behest of Hitler or anticipating his desires, set fire to the museum and burned the invaluable Roman artifacts.

It seems that a financial swindle has delayed (if not ended) Frenchman Michel Fournier's bid to set a new record for the highest altitude parachute jump.
Protected only by a pressure suit, somewhat alike to an astronaut's spacesuit, Fournier was planning to jump from a high altitude balloon at 130,000 feet (well into the stratosphere) and free fall long enough to accelerate and drop faster than the speed of sound before pulling the ripcord to open his parachute.

The Great Orme Copper Mine in Wales is listed in the Guinness Book of World Records as the world's largest Bronze Age copper mine. The History Channel has called it the largest copper mine in the world - period. They say it is only about five-percent explored, and they have already uncovered more than five miles of Bronze Age tunnels and over 30,000 Bronze Age mining picks made from deer antlers. Elsewhere it's posted that prehistoric miners recovered enough copper worldwide to smelt more than ten million Bronze Age axes - although I can't find another source for that.If you really wanted to (!), you could listen online to this thirty minute audio clip about the mine from the BBC ... http://www.bbc.co.uk/radio4/science/...m_20030826.ram ... if a new icon appears on your Mac or PC desktop, you may have to "click" on it to start the audio playback.In the 19th century, the old mine workings were assumed to be Roman, but since serious modern excavation began in 1987, over four miles of tunnels dating from 1900 to 600 BC - long before the Roman era in Britain - have been surveyed. In 1995 Mark Randall (in a University College London dissertation) estimated that up to 1,769 tonnes of copper metal were extracted from the mine during the Bronze age. This figure, based only on the surveyed area of the workings, would make the Great Orme the pre-eminent source of copper in the Bronze Age. http://www.data-wales.co.uk/orme.htm

Kittinger bailed out of a balloon at 103,000 feet. A civilian attemt to beat the record resulted in a fatality, when the faceplate of the suit blew out. I only recall the first name as Nick." I made a couple efforts to break the Canadian high altitude record of 35,000 feet, far short of the world record, but I was unable to do so. Last I heard, the US air force stated, "The effects of super-sonic speeds on a parachutist and his equipment are unknown at this time."
