In pictures: Oman's empty quarter (BBC)














This was the view from within the tent one night. The total lack of light pollution made star trails visible.




British teacher Mark Evans and New Zealand photographer John Smith spent four weeks exploring the desert in Oman's Empty Quarter.

The pair started near the border of Yemen, Saudi Arabia and Oman, and travelled north-east towards the famous Umm al-Samim quicksands. This shows the approach to the summit of Oman's highest dune.

They spent time with people in desert communities. This camel has won Oman's revered 'Most beautiful camel' award. Her owner, Sheikh Mohammed, lives in a small settlement 1km from Saudi Arabia.

Offering hospitality to travellers is still a key part of desert culture.

The pair made their journey by car, but they slept under traditional Bedouin tents. This was the view from within the tent one night. The total lack of light pollution made star trails visible.

Dancing black hole twins spotted - (BBC Article)

Reseachers have seen the best evidence yet for a pair of black holes orbiting each other within the same galaxy.

While such "binary systems" have been postulated before, none has ever been conclusively spotted.

The new black hole pair is dancing significantly closer than the prior best binary system candidate.

The work, published in the journal Nature, is in line with the theory of growth of galaxies, each with a black hole at its centre.

The theory has it that as galaxies near each other, their central black holes should orbit each other until merging together.

But evidence for black holes nearing and orbiting has so far been scant.

As matter falls into black holes, it emits light of a characteristic colour that in turn gives information about the direction in which the black hole is moving.

Because they are orbiting each other, astronomers have suggested that binary black hole systems would emit two beams, each a slightly different colour.

Todd Boroson and Tod Lauer of the National Optical Astronomy Observatory analysed some 17,500 spectra from the Sloan Digital Sky Survey, and found such a pair coming from a distant quasar.

The researchers estimate that the two light sources come from black holes between 20 million and one billion times heavier than the sun.

The black holes are separated by an estimated distance of less than a third of a light-year - cheek-to-cheek by black hole standards and significantly more than the postulated binary system spotted by the Chandra X-ray Observatory in 2003.

The pair are estimated to dance around one another every 100 years.

Because they are moving with respect to the Earth as well as to each other, observations of their movement over the next few years could prove that they are in fact the first partnered pair of black holes.

"Previous work has identified potential examples of black holes on their way to merging, but the case presented by Boroson and Lauer is special because the pairing is tighter and the evidence much stronger," said Jon Miller, an astronomer at the University of Michigan.

8 Amazing Holes
These holes are not only amazing, but some of them are really terrifying - especially #8! The sheer scale of these holes reminds you of just how small one individual is in the scheme of things.

1. KimberleyBig Hole - South Africa

Apparently the largest ever hand-dug excavation in the world,
this 1097 meter deep mine yielded over 3 tons of diamonds
before being closed in 1914.
















2.Glory Hole - Monticello Dam, California
A glory hole is used when a dam is at full capacity and water needs to be drained from the reservoir



















3.BinghamCanyon Mine, Utah

This is supposedly the largest man-made excavation on earth. Extraction began in 1863 and still continues today, the pit increasing in size constantly. In its current state the hole is miles deep and 2.5 miles wide.















4.Great Blue Hole , Belize



This incredible geographical phenomenon known as a
blue hole is situated 60 miles off the mainland of Belize .
There are numerous blue holes around the world,
but none as stunning as this one.

















5.Mirny Diamond Mine , Serbia

I'm pretty sure most people have seen this one.
It's an absolute beast and holds the title of largest
open diamond mines in the world. At 525 meters
deep, with a top diameter of 1200 meters, there's
even a no-fly zone above the hole due to a few
helicopters having been sucked in.









6.Diavik Mine, Canada

The mine is so huge and the area so remote that it has
its own airport with a runway large enough to accommodate a
Boeing 737.
It looks equally cool when the surrounding water is frozen
.







7.Sinkhole in Guatemala

These photos are of a sinkhole that occurred
early this year in Guatemala . The hole swallowed
a dozen homes and killed at least 3 people.







And the really terrifying one? #8



Try This. Lets see if you can do ...

Joke: Microsoft vs GM

Bill Gates reportedly compared the computer industry with the auto industry and stated:

"
If GM had kept up with technology like the computer industry has, we
would all be driving twenty-five dollar cars that got 1,000 miles to
the gallon
."

In response to Bill's comments, General Motors issued a press release
stating :

"
If GM had developed technology like Microsoft, we would all be
driving cars with the following characteristics:

1) For no reason whatsoever your car would crash twice a day.

2) Every time they painted new lines on the road you would have to
buy a new car.

3) Occasionally your car would die on the freeway for no reason, and
you would just accept this, restart and drive on.

4) Occasionally, executing a manoeuvre such as a left turn, would
cause your car to shut down and refuse to restart, in which case you
would have to reinstall the engine.

5) Only one person at a time could use the car, unless you
bought "Car95" or "CarNT". But then you would have to buy more seats.

6) Macintosh would make a car that was powered by the sun, reliable,
five times as fast, and twice as easy to drive, but would only run on
five percent of the roads.

7) The oil, water temperature and alternator warning lights would be
replaced by a single "general car default" warning light.

8) New seats would force everyone to have the same size butt.

9) The airbag system would say "Are you sure?" before going off.

10) Occasionally for no reason whatsoever, your car would lock you
out and refuse to let you in until you simultaneously lifted the door
handle, turned the key, and grab hold of the radio antenna.

11) GM would also require all car buyers to also purchase a deluxe
set of Rand McNally road maps (now a GM subsidiary), even though they
neither need them nor want them. Attempting to delete this option
would immediately cause the car's performance to diminish by 50% or
more. Moreover, GM would become a target for investigation by the
Justice Department.

12) Every time GM introduced a new model car buyers would have to
learn how to drive all over again because none of the controls would
operate in the same manner as the old car.

13) You'd press the "start" button to shut off the engine

IT Manager: Joke

A hot-air balloonist realises he is lost, and so reduces height to ask directions from a man on the ground: "Excuse me, can you tell me where I am?"

"Yes," says the man below. "You're in a hot-air balloon, hovering about 30 feet above this field."

"You must work in Information Technology," says the balloonist.

"I do," replies the man. "How did you know?"

"Well," says the balloonist, "everything you have told me is technically correct, but it's no use to anyone."

The man below is miffed. "You must work in business as a manager," he says.

"I do," replies the balloonist, "but how did you know?"

"Well," says the man, "you don't know where you are, or where you're going, but you expect me to be able to help. You're in the same position you were before we met, but now it's my fault."
