A federal jury in Oregon has awarded $18.6 million to a woman who spent two years unsuccessfully trying to get Equifax Information Services to fix major mistakes on her credit report.

Julie Miller of Marion County was awarded $18.4 million in punitive damages and $180,000 in compensatory damages, though Friday's award against one of the nation's major credit bureaus is likely to be appealed, The Oregonian reported.

The jury was told she contacted Equifax eight times between 2009 and 2011 in an effort to correct inaccuracies, including erroneous accounts and collection attempts, as well as a wrong Social Security number and birthday. Her lawsuit alleged the Atlanta-based company failed to correct the mistakes.

"There was damage to her reputation, a breach of her privacy and the lost opportunity to seek credit," said Justin Baxter, a Portland attorney who worked on the case with his father and law partner, Michael Baxter. "She has a brother who is disabled and who can't get credit on his own, and she wasn't able to help him."

Tim Klein, an Equifax spokesman, declined to comment on specifics of the case, saying he didn't have any details about the decision from the Oregon Federal District Court.

Miller discovered the problem when she was denied credit by a bank in early December 2009. She alerted Equifax and filled out multiple forms faxed by the credit agency seeking updated information. She had found similar mistakes in her reports with other credit bureaus, Baxter said, but those companies corrected their errors.

A Federal Trade Commission study earlier this year of 1,001 consumers who reviewed 2,968 of their credit reports found 21 percent contained errors. The survey found that 5 percent of the errors represented issues that would lead consumers to be denied credit.

19^12 / approximately 2.213 x 10^15 / approximately 2 quadrillion

The expression "nineteen to the dozen" means something is going really fast.

 Where id the phrase come from?

The usual meaningis to do something at a great rate. It most often refers to speed of speaking, as in this instance from the Daily Mail of 23 October 2003: “Talking nineteen to the dozen, her conversation is still peppered with outrageous references and bawdy asides.” The idea is that the rate of talking is so great that when other people say merely a dozen words, the speaker gets in 19. It’s also sometimes used to describe rapid heartbeat in times of danger, and to refer to other fast-moving or fast-changing things (like dogs’ tails).

Nobody seems to have the slightest idea why 19 is the traditional number to use here, but it has been in that form ever since it was first recorded in the eighteenth century.

There is a story about it which associates it with the efficiency of Cornish beam engines. It is said that such engines in the Newcomen era of the eighteenth century could pump 19,000 gallons of water out of a tin mine while burning only 12 bushels of coal. I am sure this is a folk tale, as an origin so specific and arcane would have been unlikely to generate a popular saying. It's more likely that the figures were quoted in some treatise and were then picked up as a way to explain the origin of this puzzling phrase. But nobody can know for sure because its early history is obscure.

The record for the most beers drunk in one night: 119, by Andre the Giant  (a wrestler who played the giant in The Princess Bride).

Born André René Roussimoff, and at adulthood stood over 7 feet & weighed over 500 pounds at his heaviest. Andre liked to drink. Born in France he had cosumed alcohol since he was a child. While wrestling for the WWF all the wrestlers would go to a certain bars after the shows in certain towns. Well one bar owner approached Andre & offered him a deal. The next time the WWF were in town, Andre would visit their bar & sit on stage, drinking beer all night allowing them to count how many. And the kicker was if Andre agreed to this, he got all his beer for free.

Andre agreed the the next time they were in town, the record was set. Andre sat on that stage for 6 hours. In that time he drank an astounding 119 beers! That's one beer every 3 minutes for six hours! Unreal. He could drink a can of beer in 2 drinks & his hands were so big you couldn't even see the can when he was holding it.  What's funny is that was one of the only times anybody ever saw Andre actually 'drunk'. (Andre passed out in the hallway of the hotel later that morning LOL)  He always seemed fine no matter how much he drank.

1390 (313+331+367+379)

In the 2007 Doctor Who episode "42", a sequence of happy primes (313, 331, 367, 379) is used as a code for unlocking a sealed door on a spaceship about to collide with a star. When the Doctor learns that nobody on the spaceship besides himself has heard of happy numbers, he asks, "Don't they teach recreational mathematics anymore?"

A prime number is a number with exactly 2 factors - itself and 1.

A happy number is a number that, when you square each digit and add the squares together, and keep doing that, eventually you get 1.
.....For example, the number 379 is happy:
.....square each digit - 3 squared is 9, 7 squared is 49, 9 squared is 81.
.....add the squares together:  9+49+81 = 139
.....repeat - 1 squared is 1, 3 squared is 9, 9 squared is 81.  1+9+81 = 91
.....repeat - 9 squared is 81, 1 squared is 1.  81+1 = 82
.....repeat - 8 squared is 64,  2 squared is 4.  64+4 = 68
.....repeat - 6 squared is 36, 8 squared is 64.  36+64 = 100
.....repeat - 1 squared is 1, 0 squared is 0, 0 squared is 0.  1+0+0 = 1
.....Eventually you get to 1.

313, 331, 367, 379 are all happy primes.

They add up to 1390, which is a happy number, but is not prime.


Neptune has a new moon, and its existence is an enigma. The object, known for now as S/2004 N1, is the first Neptunian moon to be found in a decade. Its diminutive size raises questions as to how it survived the chaos thought to have created the giant planet's other moons.

The faint moon was discovered in archived images from the Hubble Space Telescope. Mark Showalter of the SETI Institute in Mountain View, California, was poring over pictures of Neptune taken in 2009 to study segments of its rings.

The rings around our outermost planet are too faint to see without taking very long-exposure pictures. However, the rings orbit so fast that taking one long shot would smear them across the frame. Showalter and colleagues gathered multiple shorter-exposure images and developed a technique to digitally rewind the orbits to the same point in time. Then they could stack several images on top of each other to reveal details of the rings.

"I got nice pictures of the arcs, which was my main purpose, but I also got this little extra dot that I was not expecting to see," says Showalter.

Stacking eight to 10 images together allowed the moon to show up plain as day, he says. When he went back and repeated the process using Hubble pictures taken in 2004, the moon was still there and moving as expected.

The tiny addition to Neptune's family is an added shock because it seems too small to have survived the formation of the other moons, according to accepted theories.

Neptune's biggest moon, Triton, is 2705 kilometres wide and orbits backwards – travelling in the opposite direction to the planet's spin. Its large size and wonky orbit led astronomers to believe that Triton was captured by Neptune's gravity about 4 billion years ago and that it destroyed whatever moons the gas giant originally had as it was settling into its new home.

"The Neptune moons we see today were probably broken up and regenerated after the arrival of Triton," says Showalter.

S/2004 N1 is about 20 kilometres across, and it has a nearly circular orbit that takes it around Neptune in 23 hours. Its orbit is squarely between Proteus, the outermost moon aside from Triton, and Larissa. These moons are 400 and 200 kilometres across, respectively. But in the post-Triton chaos, such a small rock should have been swept up to become part of Proteus, or broken up by interloping asteroids sometime after the system settled down.

"How you can have a 20-kilometre object around Neptune is a little bit of a puzzle," says Showalter. "It's far enough away that its orbit is stable. Once you put it there it will stay there. The question is, how did it get there?"

A more immediate question may be what to call this new and unusual moon. Neptune's other natural satellites are named after minor water deities in Greek and Roman mythology, an official naming convention set up by the International Astronomical Union (IAU). Showalter and colleagues also recently discovered two new moons around Pluto and put their names to a public vote – although the IAU had the final say.

"Compared to work we recently did naming the moons of Pluto, there's not quite as colourful a cast of characters to work with, but there is still an interesting list of sea creatures one can choose from," he says.

For now, Showalter and the discovery team do not have a favourite in mind: "We don't really have a name for it. It's just 'that little moon', because S/2004 N1 does not roll off the tongue."

 In the television show Futurama, there is a taxicab number 87539319.


A famous anecdote of the British mathematician G. H. Hardy regarding a visit to the hospital to see the Indian mathematician Srinivasa Ramanujan. In Hardy's words:
I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavorable omen. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways."

Ever since then, the lowesat number that can be expressed as the sum of 2 positive cubes in n different ways is called a "taxicab number"  1729 is Taxicab(2) because n is 2.

87539319 is Taxicab(3).  It is the lowest number that can be written as the sum of 2 positive cubes in 3 different ways.

Taxicab(3) = 87539319
= 1673 + 4363
= 2283 + 4233
= 2553 + 4143

This property was discovered in 1957.
