Freakonomics » Lottery Loopholes and Deadly Doctors: A New Freakonomics Radio Podcast
"Also in this episode, we take a broader look at financial literacy – or, really, financial illiteracy. In general, Americans aren’t very good at the basics of saving, investing, and retirement planning. So we want to know: How do we improve our grade?  We’ll hear from one scholar who wants to put financial literacy in schools and another who thinks that would be a waste of time. Guests also include two members of President Obama’s economic team and National Book Award-winner Sherwin Nuland.

And if education isn’t the route to financial literacy, maybe we can learn something from how one Los Angeles hospital solved the problem of its doctors failing to wash their hands."

Jersey Jazzman: No Child Let Ahead
"Put yourself in an Eighth Grade geometry (a high level of mathematics for that age) teacher's shoes for a minute. Your kids will be taking a test that mostly covers content from last year. Your livelihood is on the line. Your ability to pay your mortgage is predicated not on your kids' abilities to pass a test in this year's content, but on last year's content.

What are you going to do? Push them ahead? Or make damn well sure they "grow" on a test based on what they did the previous year?"

Makematics: turning CS research into maker tools
"No generation of artists has ever been more dependent on scientific and technical advances than today’s. Today’s artists work on computers. Advances in computer science and related mathematical fields underlie everything that digital artists make. Recently these advances have lead to the advent of whole new creative fields like interactive art, generative graphics, data visualization, and digital fabrication.

In order to produce excellent and novel work in these new fields, artists have had to learn computational and mathematical techniques. They started with basic material like trigonometry for 2D games and graphics, the rudiments of computer vision for interactive installations, and primitive signal processing for embedded electronics.

Increasingly these new creative fields are becoming the basis of art and design across our culture. And these techniques are becoming the foundation of a new kind of art and design education."

Kill Math
"The power to understand and predict the quantities of the world should not be restricted to those with a freakish knack for manipulating abstract symbols.

When most people speak of Math, what they have in mind is more its mechanism than its essence. This "Math" consists of assigning meaning to a set of symbols, blindly shuffling around these symbols according to arcane rules, and then interpreting a meaning from the shuffled result. The process is not unlike casting lots."

This mechanism of math evolved for a reason: it was the most efficient means of modeling quantitative systems given the constraints of pencil and paper. Unfortunately, most people are not comfortable with bundling up meaning into abstract symbols and making them dance. Thus, the power of math beyond arithmetic is generally reserved for a clergy of scientists and engineers (many of whom struggle with symbolic abstractions more than they'll actually admit).

We are no longer constrained by pencil and paper…"

dy/dan » On iBooks 2 And iBooks Author
"Algebra, as designed by McGraw-Hill for iBooks 2, is lighter by pounds. It's indexed for search. It's quick. You can highlight the text and insert notes. It removes one layer of abstraction between students and tools that already existed. Rather than accessing quizzes, tutorials, and enrichment videos by loading a CD-ROM into a computer or entering a password into a website, they're a tap away.

That's where the differences end. Students still interact with mathematics as they always have…

What I'm saying, basically, is that I'd have to modify, adapt, and extend the McGraw-Hill iBook in all the same ways that I modified, adapted, and extended the McGraw-Hill print textbook. We'd pull out the iBook just as infrequently as its printed sibling."

dy/dan » Blog Archive » It’s Called iBooks Author, Not iMathTextbooks Author, And The Trouble That Results
"Print textbooks are powerless to facilitate that moment right there. Teachers can't facilitate it, not at anywhere near the speed and ease I'm suggesting. iBooks Author can't facilitate it either, but if it could — if it had some kind of "Q&A;" widget that lived alongside its other widgets and basically copied all the options from Google Forms — I'd find the platform difficult to resist.

But iBooks Author doesn't exist for the pleasure of math education publishers or even education publishers. "This is about Apple versus Amazon for who will sell digital literature in the future," says Audrey Watters. "This isn't really about textbooks."

iBooks Author serves publishers, period. It'll help you publish your Firefly fan fiction, your autobiography, or your Nana's recipe collection. It's extremely useful, broadly speaking, which inevitably means that, narrowly speaking to math education publishers, it's much less useful."

How to Fix Our Math Education - NYTimes.com
"Imagine replacing the sequence of algebra, geometry and calculus with a sequence of finance, data and basic engineering. In the finance course, students would learn the exponential function, use formulas in spreadsheets and study the budgets of people, companies and governments. In the data course, students would gather their own data sets and learn how, in fields as diverse as sports and medicine, larger samples give better estimates of averages. In the basic engineering course, students would learn the workings of engines, sound waves, TV signals and computers. Science and math were originally discovered together, and they are best learned together now."

Eric Schmidt, chairman of Google, condemns British education system | Technology | The Guardian
""Over the past century, the UK has stopped nurturing its polymaths. You need to bring art and science back together."…<br />
<br />
"It was a time when the same people wrote poetry and built bridges," he said. "Lewis Carroll didn't just write one of the classic fairytales of all time. He was also a mathematics tutor at Oxford. James Clerk Maxwell was described by Einstein as among the best physicists since Newton – but was also a published poet."<br />
<br />
Schmidt's comments echoed sentiments expressed by Steve Jobs, the chief executive of Apple, who revealed this week that he was stepping down. "The Macintosh turned out so well because the people working on it were musicians, artists, poets and historians – who also happened to be excellent computer scientists," Jobs once told the New York Times."

13-Year-Old Makes Solar Power Breakthrough by Harnessing the Fibonacci Sequence | Inhabitat - Green Design Will Save the World
"While most 13-year-olds spend their free time playing video games or cruising Facebook, one 7th grader was trekking through the woods uncovering a mystery of science. After studying how trees branch in a very specific way, Aidan Dwyer created a solar cell tree that produces 20-50% more power than a uniform array of photovoltaic panels. His impressive results show that using a specific formula for distributing solar cells can drastically improve energy generation. The study earned Aidan a provisional U.S patent - it's a rare find in the field of technology and a fantastic example of how biomimicry can drastically improve design."<br />

"I’m Paul Salomon, and Math/ed stuff is constantly rolling around and boiling over in my mind.  I don’t value grades, scores, or top-down standards.  I want schools that honor the people within them and let student interest drive their culture.  Aside from that, a whole mess of ideas are careening around inside my head, making me question everything I do.  What is possible at school?  What’s math worth? How do people become experts?  How do I get better?  These are the things I’m working on at Saint Ann’s School in Brooklyn, in the hopes that I can better share engaging mathematics."

Controversy over the Christakis-Fowler findings on the contagion of obesity — The Monkey Cage
"To return to Christakis and Fowler: I’d be interested to see their reply to the criticisms of Lyons and others. Perhaps they’ll simply step back a few paces and say that the Framingham data are sparse, that they’ve found some interesting patterns that they hope will inspire further study in other contexts.<br />
<br />
After all, even if the Framingham results were unambiguously statistically significant, robust to reasonable models of measurement error, and had a clean identification strategy—even then, it’s just one group of people. In that sense, the debate about Christakis and Fowler’s particular claims, interesting and (methodologically) important as it is, is only part of a larger story of personal networks, health, and behavior. I hope that Lyons’s article and any responses by Christakis, Fowler, and others will be helpful in designing and analyzing future studies and in piecing together the big picture."

Buckminster Fuller - Wikipedia
"He attended Froebelian Kindergarten. Spending much of his youth on Bear Island, in Penobscot Bay off the coast of Maine, he had trouble with geometry, being unable to understand the abstraction necessary to imagine that a chalk dot on the blackboard represented a mathematical point, or that an imperfectly drawn line with an arrow on the end was meant to stretch off to infinity. He often made items from materials he brought home from the woods, and sometimes made his own tools. He experimented with designing a new apparatus for human propulsion of small boats.<br />
<br />
Years later, he decided that this sort of experience had provided him with not only an interest in design, but also a habit of being familiar with and knowledgeable about the materials that his later projects would require. Fuller earned a machinist's certification, and knew how to use the press brake, stretch press, and other tools and equipment used in the sheet metal trade."

How I Failed, Failed, and Finally Succeeded at Learning How to Code - Technology - The Atlantic
"Kids are naturally curious. They love blank slates: a sandbox, a bag of LEGOs. Once you show them a little of what the machine can do they'll clamor for more. They'll want to know how to make that circle a little smaller or how to make that song go a little faster. They'll imagine a game in their head and then relentlessly fight to build it.
Along the way, of course, they'll start to pick up all the concepts you wanted to teach them in the first place. And those concepts will stick because they learned them not in a vacuum, but in the service of a problem they were itching to solve.

Project Euler, named for the Swiss mathematician Leonhard Euler, is popular (more than 150,000 users have submitted 2,630,835 solutions) precisely because Colin Hughes…crafted problems that lots of people get the itch to solve. And it's an effective teacher because those problems are arranged like the programs in the ORIC-1's manual, in what Hughes calls an "inductive chain":"

Ukulele Dayz « Sarcasymptote
"What I’ve been doing a better job of, though, (but see footnote 2 and know that IT STILL ISN’T GOOD), is backing off and letting them struggle…<br />
<br />
…brought my ukulele to school one day because I had a rehearsal to go to after, and I started playing it in class as a joke. Not only did they not complain, but they said they kind of liked it[3]. So I started to do it more. And I noticed something. They stopped asking me for help when I was playing ukulele and would instead turn to their neighbor and ask them. Good God, that is what I’d been asking you guys to do forever! Hot damn! It was beautiful: I could still move around and check up on their work, but when they asked me to help them, I would just say, “Ugh, I’m too busy playing ukulele.”

Khan Academy and the mythical math cure « Generation YES Blog
"There is no doubt that Khan Academy fills a perceived need that something needs to be fixed about math instruction. But at some point, when you talk about learning math, you have to define your terms. If you are a strict instructionist – you are going to love Khan Academy. If you are a constructivist, you are going to find fault with a solution that is all about instruction. So any discussion of Khan Academy in the classroom has to start with the question, how do YOU believe people learn?<br />
<br />
I have more to say about Khan Academy and math education in the US — this post turned into 4 parts!<br />
<br />
Part 1 – Khan Academy and the mythical math cure (this post)<br />
Part 2 – Khan Academy – algorithms and autonomy<br />
Part 3 – Don’t we need balance? and other questions<br />

"Can you do that? Can you just plug in some made up thing and end up with solutions? Can you simply draw some imaginary lines and end up with a better map? You don’t expect to be acclaimed as a great scientist until you discover something, something big and useful, but shouldn’t this something have to be real? Let’s jump ahead 125 years. It’s 1922 and Ludwig Wittgenstein has just published his Tractatus Logico-Philosophicus which insists, among other things, that the limits of my language mean the limits of my world. Or, put another way: how you say it is how you think it. And, more dramatically: if you can’t say it, you can’t think it. And, if you can’t think it, how can you solve it?"

The Way You Learned Math Is So Old School : NPR
"there's a reason elementary schools are teaching arithmetic in a new way.<br />
<br />
"…largely to reflect the different needs of society. No one ever in their real life anymore needs to — & in most cases never does — do the calculations themselves."<br />
<br />
Computers do arithmetic for us…but making computers do the things we want them to do requires algebraic thinking. For instance, take a computer spreadsheet. The computer does all the calculations for you automatically. But you have to write the macros that tell it what calculations to do —& that is algebraic thinking.<br />
<br />
"You cannot become good at algebra w/out a mastery of arithmetic, but arithmetic itself is no longer the ultimate goal." Thus the emphasis in teaching mathematics today is on getting people to be sophisticated, algebraic thinkers.<br />
<br />
That doesn't mean that kids can skip learning their multiplications tables. "But the way it's taught now is you get to multiplication tables by understanding number system & what numbers mean"

n+1: N1BReading, Part 2
"The Lost Books of the Odyssey by Zachary Mason—that book was awesome. It came out in 2007 from a tiny publisher & was republished by FSG last year, at which point my esteemed friend Mansbach gave it a review…I think he was less enthusiastic than I have since become. The book is not just a game w/ the Odyssey…but a genuine rewriting of it. For what was the thing about Odysseus? He was crafty; he was smarter than everyone else. But what did it mean to be smarter than a bunch of peasants; what did it mean to be a logician 600 years before the birth of Pythagoras? Mason puts the ingeniousness, the cleverness, & the math back into Odysseus & back also into contemporary literature. It’s interesting that, according to the jacket copy, Mason in his day-to-day life works on AI: Computers too are pre-logical, full of force but lacking reason. Working with computers all those years, Mason must himself have come to feel like Odysseus among the Agamemnon-era Greeks." —Keith Gessen

How Design Can Get Kids On the Path to Tech Careers | Co.Design
"whenever you say the word 'school,' it conjures up mental images & models of our experiences and behavior in a place -- & accompanying that 'place model' is a kaleidoscope of memories & emotions about how that place looked & worked -- how we felt in it, what was rewarded, celebrated & expected, & who we were supposed to be as learners in that place. Unfortunately, many of these mental models of how we should learn in school are completely at odds w/ how real learning happens & how it's demonstrated in the real world. False proxies for learning often erode our children's vibrant intellectual & creative potentials because they diminish the excitement of real learning & discovery. Everyone knows that finishing a course and a textbook does not mean achievement. Listening to a lecture does not mean understanding. Getting a high score on a high-stakes standardized test does not mean proficiency. Credentialing does not mean competency. Our children know it, too, yet it persists."

Why the other lines always seem to move faster than yours
"Erlang found out how many telephone lines the company needed, given the average number of calls per hour. Similarly, you can figure out how many checkout lines you need, given the average number of customers. It turns out the best arrangement is to have a single line, and the next customer goes to the next available register. There's less chance of blockage from a single delay.<br />
But people don't like doing that apparently, and so assuming random selection, ending up in the slow line comes down to simple probability.<br />
<br />
Another way to think about this problem is in terms of time. You wait when you're in a slow line. You move when you're in a fast line. So the longer amounts of time spent waiting feel more significant (even though it might be a single pick) than when you made the fast picks."

Simpson's paradox - Wikipedia
"In probability and statistics, Simpson's paradox (or the Yule-Simpson effect) is an apparent paradox in which a correlation (trend) present in different groups is reversed when the groups are combined. This result is often encountered in social-science and medical-science statistics,[1] and it occurs when frequency data are hastily given causal interpretations.[2] Simpson's Paradox disappears when causal relations are brought into consideration (see Implications to Decision Making)."

The Good Show - Radiolab
"In this episode, a question that haunted Charles Darwin: if natural selection boils down to survival of the fittest, how do you explain why one creature might stick its neck out for another?<br />
<br />
The standard view of evolution is that living things are shaped by cold-hearted competition. And there is no doubt that today's plants and animals carry the genetic legacy of ancestors who fought fiercely to survive and reproduce. But in this hour, we wonder whether there might also be a logic behind sharing, niceness, kindness ... or even, self-sacrifice. Is altruism an aberration, or just an elaborate guise for sneaky self-interest? Do we really live in a selfish, dog-eat-dog world? Or has evolution carved out a hidden code that rewards genuine cooperation?" [Related: http://www.nytimes.com/2010/07/11/books/review/deWaal-t.html?pagewanted=all ]

A Physicist Turns the City Into an Equation - NYTimes.com ["According to data, when a city doubles in size, every measure of economic activity increases by approximately 15% per capita.]
One quote“A human being at rest runs on 90 watts,” he says. “That’s how much power you need just to lie down. And if you’re a hunter-gatherer and you live in the Amazon, you’ll need about 250 watts. That’s how much energy it takes to run about and find food. So how much energy does our lifestyle [in America] require? Well, when you add up all our calories and then you add up the energy needed to run the computer and the air-conditioner, you get an incredibly large number, somewhere around 11,000 watts. Now you can ask yourself: What kind of animal requires 11,000 watts to live? And what you find is that we have created a lifestyle where we need more watts than a blue whale. We require more energy than the biggest animal that has ever existed. That is why our lifestyle is unsustainable. We can’t have seven billion blue whales on this planet. It’s not even clear that we can afford to have 300 million blue whales.”

Rule 30 - Wikipedia
"Rule 30 is a one-dimensional binary cellular automaton rule introduced by Stephen Wolfram in 1983. Wolfram describes it as being his "all-time favourite rule" and details it in his book, A New Kind of Science. Using Wolfram's classification scheme, Rule 30 is a Class III rule, displaying aperiodic, chaotic behaviour.<br />
<br />
This rule is of particular interest because it produces complex, seemingly-random patterns from simple, well-defined rules. Because of this, Wolfram believes that rule 30, and cellular automata in general, are the key to understanding how simple rules produce complex structures and behaviour in nature."

Education Week: Is There an Algebra Overkill?
"No doubt, algebra is a steppingstone to higher mathematics and quite necessary in professions that require extensive knowledge of math. Too, it offers insights not only into numbers, but also into general problem-solving separately. It is also reasonable for most students to have some experience with it before they leave school.<br />
<br />
The difficulty, however, is assuming that algebra, in itself, will greatly increase everyone's ability to do the kind of mathematics that most people do in ordinary life."

SpeEdChange: Of time and technology...
"So when I sat in an elementary school last week and saw a lesson on time and quarter hours I wondered why we were still doing that - other than, in this case, mandates from the Commonwealth of Virginia? So I asked teachers sitting near me, and only one in five still tended to use those old terms.<br />
<br />
There is a lovely antiquity, I suppose, in the nature of that circular clock. But it encourages imprecion and confusion, and barely is used anymore in a functional way.<br />
<br />
So why are we teaching it?"

How Einstein Started Solving Its Math Problem - voiceofsandiego.org: Schooled: The Education Blog
"The math scores at Einstein Academy didn't add up. Kids aced math in the younger grades at the South Park school, a respected charter with enviable test scores.<br />
<br />
Yet when they hit algebra, their scores plummeted. Three years ago, just 9 percent of eighth graders in its sister middle school were proficient in algebra on state tests — even kids who seemed to be math whizzes before.<br />
<br />
Instead of jumping on algebra and assuming that something was amiss in eighth grade, Einstein stepped back and examined its whole math curriculum from kindergarten up.<br />
<br />
What it found was surprising. The problem started much earlier than eighth grade, back when kids were acing math. Einstein's students were developing too many shortcuts and not enough understanding. While that had worked in the short term, it ultimately shortchanged kids."

Mathematics (song) - Wikipedia
""Mathematics" is a b-side single from Mos Def's solo debut album, Black on Both Sides. It contains lyrics about various social issues and asks the listener to add them up and come to conclusions about them. Many references to numbers are found in this song and at times, Mos Def rhymes statistics in numerical order. The song is produced by DJ Premier whose famous scratch samples make up the song's bridge. Premier has called it one of his favorite beats."

Cities - Radiolab
"In this hour of Radiolab, we take to the street to ask what makes cities tick.<br />
<br />
There's no scientific metric for measuring a city's personality. But step out on the sidewalk, and you can see and feel it. Two physicists explain one tidy mathematical formula that they believe holds the key to what drives a city. Yet math can't explain most of the human-scale details that make urban life unique. So we head out in search of what the numbers miss, and meet a reluctant city dweller, a man who's walked 700 feet below Manhattan, and a once-thriving community that's slipping away."

Karl Fisch: Do you Believe in Algebra? (VIDEO)
"But it still begs the question of whether all students need these 118 standards. For example, do you believe that all students (scratch, that, all people) need to know that "there is a complex number i such that i2 = -1, and every complex number has the form a + bi with a and b real?" (CCSS, N-CN 1). Or how about "prove the Pythagorean identity sin2(x) + cos2(x) = 1 and use it to find sin(x), cos (x), or tan(x) and the quadrant of the angle?" (CCSS, F-TF 8).<br />
<br />
(My not-so-modest proposal is that no state legislature is allowed to require standards that they couldn't demonstrate proficiency on themselves. Since they are clearly successful adults and they are saying that these standards are necessary for all students to be successful, surely they'd be able to demonstrate proficiency by taking the same tests our students do. But I digress.)"

Autism and HIV: when maths can be misleading - Telegraph
"Moreover, the number of people involved was small: 20 with autism, 20 without. With that small a group, it’s hard to tell whether any association that shows up is meaningful. You can train a computer using photos of the family cat, and it will calculate whichever combination of size, colour, and whisker length best detects autism in its owner. There are so many potential combinations that in all likelihood one of them will appear to perform pretty well. But try it on another bunch of people, and the odds are it will fail."

NOVA | A Radical Mind [Interview with Benoit Mandelbrot via: http://preoccupations.tumblr.com/post/1334513534/benoit-mandelbrot-1924-2010-nova-a-radical]
"You’ve been interested in the revolution in thinking that took place during Renaissance. I love the term “natural philosophy”…<br />
<br />
It is lovely indeed. Too bad it hasn’t been used since 18th century.<br />
<br />
What does that term mean to you?<br />
<br />
Before Galileo, philosopher was somebody who studied great books. Many of those people were extraordinarily brilliant, but their absolute obedience to books was destructive. What Galileo did was to say natural philosophy is written in the Great Book of Nature & one must move from reading books in library to reading books around us—that is, use experimental method & believe in power of the eye. That was the big thing. Newton was called a natural philosopher. & in 18th century, professions of mathematics & physics were not deeply distinguished, but now they are.<br />
I’m certainly a philosopher entranced with unifying ideas. However, I don’t only study books; I study nature. Also art of the past, for purpose of finding artifacts that I could embrace."

""Reading is defined as getting information from a recorded source into your head, Writing is defined as getting information from your head into a form which others can access." And to which I might have added, "Arithmetic is defined as having a common system for sharing quantifiable data.""

"reason US standardized test results collapse after 4th grade...tests simply ask kids to regurgitate processes we've been banging into them for first 4 years of school. They do that well enough. But the processes really don't connect to most on functional level, so when they take later content-driven evaluation tests, they fail, because they are not accessing content...only know how to "read" to "read." I see this all the time, quick, "fluent" readers who have no idea what they've just read, or why. Kids who form letters perfectly but who can't express themselves. Kids w/ memorized math facts but no ability to leap into algebra or beyond...

"10 things that were constantly reinforced during my 12 years of public school in America that had to be unlearned as an adult desiring to be an entrepreneur.

1. Fit in instead of be original

2. Follow the rules instead of questioning why they exist

3. Helping others is cheating despite the fact that everything you do as a successful adult is a team effort

4. Have good handwriting instead of teaching me to type

5. Do it because the teacher said so, instead of teaching me to understand why doing it is important

6. Don’t challenge authority instead of teaching me that I deserve respect too

7. Get good grades in all my classes, even though I will never do trigonometry ever in life. (Sine these nuts. lol)

8. Don’t fail instead of teaching me to value trial and error

9. Debating and arguing with friends is a bad thing, instead of encouraging independent thought and self confidence

10. Be a generalist and learn things I hate, instead of developing my genius at things that i like.

More Dumbshit that I still dont understand.

*Getting to school late will be punished by making you stay home for 3 days…WTF

*Memorize stuff that now can be looked up on Google.

*Learn to do calculus by hand, despite being required to purchase a $200 calculator.

*Appearing smart is more important than being effective…. REALLY?

Redesigning Education: Building Schools for Science, Technology, Engineering, and Math | Co.
"Now is the time to reflect on the reasons for students' disengagement from science and technology subjects. We need to treat STEM as a pedagogical approach and design an environment to support this new way of teaching. Brian Greene, a best-selling author and theoretical physicist best known for his work in string theory, talks passionately about how we have educated the curiosity out of the math and sciences. Greene says that we have paralyzed our children with the fear of being wrong. Risk-taking and making mistakes are critical to the scientific process. This fear of being wrong has resulted in disengagement from science and mathematics: learning science and math is a drag! He makes a convincing assessment of the problems with our current science education system and stops just short of demanding a new pedagogy to bring excitement and relevance back to the learning of science and math."

The calculus of friendship: what a teacher and a student learned about life while corresponding about math ... - Google Books
"The Calculus of Friendship is the story of an extraordinary connection between a teacher and a student, as chronicled through more than thirty years of letters between them. What makes their relationship unique is that it is based almost entirely on a shared love of calculus. For them, calculus is more than a branch of mathematics; it is a game they love playing together, a constant when all else is in flux. The teacher goes from the prime of his career to retirement, competes in whitewater kayaking at the international level, and loses a son. The student matures from high school math whiz to Ivy League professor, suffers the sudden death of a parent, and blunders into a marriage destined to fail. Yet through it all they take refuge in the haven of calculus--until a day comes when calculus is no longer enough. Like calculus itself, The Calculus of Friendship is an exploration of change..."

"So employing an internal data griot makes a lot of sense: someone who can spend the time looking for both large trends and individual needs and uses that illuminate and portend.

The Economist (sub required) posits them as data scientists (a position Flickr are currently looking for), but this misses the ability to ask interesting questions, and having hunches – being so immersed in the data that relevancy screams out."
