Back in 1997, my new house was in the slow process of changing from plans on paper into bricks on concrete. One of the tasks that has to be done early on is to lay out the shape of the house accurately onto the land. My builder uses a sub-contractor to do that - and I had occasion to watch him work. He arrived in a beat up old pickup truck with four 'migrant workers' sitting in the back. In order to lay out the initial 'bounding rectangle' of the building, they follow this algorithm:

* Measure a baseline for the long edge of the rectangle. Mark it with two stakes hammered into the ground and tie a length of nylon string between them.

* Tie a second piece of string to one of the stakes and measure out the width of the rectangle along it. Eyeball the angle between the new edge and the baseline so it's roughly 90 degrees and you have an 'L' shape. One guy holds the string there.

* Do the same at the other end of the baseline. Now you have a 'U' shape and two guys are holding the open ends of the strings.

* Take a third piece of string - equal in length to the length of the rectangle. Give one end to each of the two guys who are already holding string. 'jiggle' them until all three strings are tight. You now have a parallelogram made of string, staked out at two corners.

* Now take two long tape measures and with one guy standing at each corner of our parallelogram, position the tape measures along the two diagonals of the parallelogram. With two guys holding the tapes on the baseline stakes and the other two holding onto the strings and shouting out the lengths of the diagonals, they jiggle the two free points until all of the strings are tight and the two diagonals tape measures are reading the same lengths. This requires a lot of shouting, cursing and everyone telling everyone else which way to move.

* Now they have a rectangle - so they bash in two more stakes and then level the whole thing with a really impressive-looking laser contraption.

Well, I watched this with some amusement - and asked why they didn't just calculate the length of the diagonal. The boss guy said that you couldn't do that - "It's impossible". I told him about Pythagoras' theorem. With the aid of a calculator (he didn't know what that funny 'square-root' key was for), I was able to show him how easy it is to calculate the length of the diagonal and do away with all the ugly 'jiggling'.

"Wow!" he said. Then he thought for a moment - "Now I'll only need three guys to hold the string!"...and fired one of them on the spot! I thought he was kidding - but the next day when they were measuring out the place for the garage, there was one less guy holding the string.

So, a 2,500 year old technological advance cost some poor guy his job.

Let me help you out here. I lived with a family of 6 whose yearly average of taxable income of $14,000 (c.2000). We received welfare ($600/month), food stamps ($250/month), and received subsidized rent via HUD ($-400/month). As you can tell, we were below the poverty line.

Now consider the average education level of those under the line. I think my family was a good example having a Vietnam-vet with a GED as a father and a middle-school-educated mother. They were not capable of finding significant income in an area that would allow "people like us" to live.

They eventually got a car-- an '80s junker on a 16% interest loan. We had 2 color televisions with cable. "Why?," you ask? because there is literally NO OTHER WAY OF ESCAPE in a society that focuses around entertainment! A one-time cost of $200 and a monthly cost of $25 is damn reasonable when you consider that most Slashdotters rarely think more than twice about upgrading their system (or buying a new one) with a pricetag of 200+.

Lastly, there's all the qualitative differences in a family that lives below the poverty line. There's frustration (an extreme understatement here) of being stuck and unable to provide. This anger is, more often than not, expressed physically with women and children on the receiving end. There's depression, lack of confidence, in ability to socialize outside of your born-in group as other groups cost money to associate with, no culture of education... there is no hope.

So, before you rain judgement from upon high based on severly miscalculated eyeball-assumptions, give it a shot.

Let's say you have some corpus with N distinct words in it. For each word w you create a "context vector" vw of length 2N. In the first N positions there are counts for the number of time each word in the corpus appears immediately to the left of the word w, and for the second N positions there are counts of the same for the right context. The angle between any two vectors in this 2N-dimensional vector space produces a measure of the distance between the two words. If you use some kind of dimensionality reduction technique to get a 2-dimensional representation, you can see that although this technique is pretty crude linguistically speaking it does pretty well. Each language has a distinct "shape" in this regard, with similar words grouped together, i.e., in English there might be a cluster of points consisting of "singular nouns," or specific parts of speech, like prepositions. It can sometimes even group words by semantic domain, depending on your corpus.

Kind like a mathematician freelancer/mercenary : You do the job, you get the money and that's it.

I mean, there are web sites for freelancer artists/web developer/coder. But there isn't one for mathematicians.

So, the only way to make money out of maths (in france) is either to teach it or to research in an university. Either way, you are a salary man.

Man, that sucks.

What is the use for those monsters maths skills, that I patiently honed all these years if I can't even make a little cash out of it/or make more money out of it that the average teacher (that really sucks at research/high lvl maths) ?

They have tremendous demand for mathematicians that can develop models to quantify risk.

This is not a trivial problem. It is quite technically challenging and requires very sophisticated mathematical skills. Oh, and you'll make more money than God.

Math majors from top schools are being recruited (along with other hard sciences, physics and CS) by banks, hedge funds, etc. and getting 6 figures right out of college. No kidding. The story is, about a decade or so ago, some hedge funds decided to try letting some really smart people (i.e. math majors from top schools) handle money. They did so well, they made a fortune and it turned the industry upside-down. Well, that might be an exaggeration, but it's more or less true.

Markets had a number of pricing inconsistencies, etc. in them, and these smart mathy people figured out how to take advantage of them. Lots of algorithms and computer programming found application to managing these hedge funds. To correct for these abuses, the markets had to close the gaps and inconsistencies these hedge funds were abusing.

Although a lot of the market problems have since been cleaned up, a lot of math is going into managing funds to maximize profit. There aren't as many people making millions off of just trading, but there's a lot of jobs in the financial industry for smart math people that still pay extremely well.

The financial industry learned its lesson: math is incredibly useful. This has already been obvious in industries like computer programming, where sophisticated math goes into designing algorithms. In the future, I think we'll continue to see other industries finding out how huge the benefits of math can be.

Otherwise, get ready for low pay unless you graduated from MIT, NYU , or Cal Tech in a program designed specifically for the "latest" applied math craze. I watched graduates from a top 10 Applied Math Program grovel for 1 year post-docs. Many went into Comp Sci AFTER receiving their PhD because they did not want to enjoy the bountiful $35K they would get as a post-doc.

By the time a place like Business Week has an article on this, the top math programs located nearby the trend

Yep, stick with your applied field and a strong math background.

## Math has always been a necessity (Score:3, Interesting)

The simple fact is that only a small percentage of the population has the requisite knowledge of mathematics, and only a small percentage of them have the passion and drive to pursue math even further. I am one of those mathephiles, and I'm proud of it. The problem with the article is that non-mathletes don't necessarily understand mathletes. It raises privacy problems and such as problems in the mathematical world, but the real fact is, math really does nothing to avert privacy. Maty can be

usedto devise algorithms which may or may not undermine privacy. The real fact is, however, that overzealous entrepreneurs will attempt to bastardize the good applications of math for their own ill gain. I don't really see a problem with the mathematical progress we make. I personally think that if businesses use math, and consumers are too stupid to realize they are being pimped, for lack of a better term, by industry, then they deserve what they get. I will still be an alert person and protect my privacy by being careful. There is no substitute for common-sense.The other problem I have is that we need to lure women and "ethnic minorities" into mathematics. Sure, it would be wonderful if there were more female mathematicians. But we can't simply set up a quota system for mathematicians. This is more of a society problem than education or anything. Big entertainment has put out this message that being intelligent is "uncool," especially when one is good at math. In fact, society scorns illiterates, but people brag about inneptities in mathematics. Look at the news media. They are preaching about this avian flu, but their already fragile case for hysteria is flattened by their fouled up statistics (no pun intended). They say the mortality rate is something like 75%. With a logistic growth model, that would knock off huge amounts of the population in its second stage, which has definitely not happened yet. But if you look at the sources of their statistics, they only accounted for people who have been confirmed with avian flu, and specifically those who died or were critically ill. The actual numbers of people who have been infected is probably much higher, and in past years many people have probably been affected by it and then overcame it, thinking it was a "normal" flu. With these people taken into account, the true mortality rate is probably much less. The lack of math knowledge in the media is terrible, because these people just utter words that they think they understand. "Mortality rate" is the ratio of deaths (with respect to something) per 1000 people. If you looked up infant mortality rate, it would be quoted as "n deaths per 1000 live births". When society en masse becomes more attentive to mathematics, then we will start to see women enter the field.

'Ethnic minorities' was the phrase that stumped me. Why do we beat around the bush and use this PC "ethnic minority" crap? I work in a physics lab with physicists, enginneers, and mathematicians. Its like the friggin' UN in there. A guy from Thailand, one from India, a Pacific Islander, a guy from China, a black guy, then two white guys (another guy and I) all work in an office. There is no clear majority! The only real fact is that we're all men. What pisses me off is that we can't say "we wish more blacks would enter the mathematics field," we have to say "we hope 'ethnic minorities' enter mathematics." Ethnic minorities are distributed all throughout mathematics in the US. Asians, Indians, and Arabs are all present in mathematical fields. Maybe when ignorance by the media is overcome, and the real truth is confronted, then we'll see mathematics interest really spike across the board.

This may surprise those of you who assumed that the British contraction is older than the N. American one, but the opposite is in fact true.

The first use of 'math' recorded in the Oxford English Dictionary is in 1849, whereas its earliest recorded entry for 'math' is in 1911, penned by the English War Poet Wilfred Owen

The well-known plural form 'mathematics' is to be compared with terms such as physics and metaphysics. In early use, the subjects were often referred to in the singular, as matamatik, fiskyke, and metaphesyk. In plural, they connoted something entirely different. For instance, physics was the title of Aristotle's collected physical treatises. 'Mathematics' would be used to denote the collection of the various branches of mathematics, such as geometry, algebra, etc. In modern usage, 'mathematic' and 'physic' have fallen by the wayside and the plural forms have taken their place.
