Why Math Might Be The Secret To School Success : NPR Ed : NPR

december 2014 by daguti

"There's plenty of evidence on the long-term importance of preschool. But why math? Morris says a 2013 study by Greg Duncan, at the University of California, Irvine's School of Education, showed that math knowledge at the beginning of elementary school was the single most powerful predictor determining whether a student would graduate from high school and attend college. "We think math might be sort of a lever to improve outcomes for kids longer term," Morris says."

Terry Moore: Why is 'x' the unknown? | Video on TED.com

june 2012 by daguti

X is unknown because when arabic was translated to spanish, there was no sound for "sh" so they used the green "kai" which looks kind of like an x... and when that was translated to english and put into textbooks, they just replaced the kai with an x.

Geoffrey West: The surprising math of cities and corporations | Video on TED.com

july 2011 by daguti

"All companies die"

evolvify-topics = Not 100% true, but tied to the fact that human constructions (cities, buildings, companies, etc) grow in the same predictable ways that nature does.

At 8:05, "Economies of scale" - tied to Charlie Munger's "mental models" - the fact that an elephant 1million times larger than a mouse doesn't need a million times more energy (economy of scale) FTA: "The bigger you are, the less needed per 'capita'" (at ~8:15)

VERY IMPORTANT: at 9:00, he lists 5 rules of biological life, which (I believe) are easily transposed to business and the universe at large.. especially rules b, c and d:

b) bigger u are, less needed per capita

c) pace of life slows w/ increasing size

d) growth is sigmoidal, reaching stable size @maturity

At 15:00 (or before), discussion regarding the "built-in" collapse for companies/societies and the need for faster and faster "innovation" or "changing of gears" to avoid collapse.

How maths killed Lehman Brothers

july 2009 by daguti

Yes, it is unfair! In fact, CDO is a lot riskier than bank deposits, but Lehman Brothers, like many investors, didn't seem to know that. Let's go back to our original model. The first source of error is that we have assumed that each investor has a 3% chance of defaulting. How do we know that? It must be from historical data. The problem is, there hasn't been a national drop of housing price since the great depression in the 1920s, so the chance that a borrower defaults was calculated on the basis of a good period when the housing prices surged. However, the housing market crashed in 2007. Many borrowers' properties are now worth even less than the loan they have to pay in the future, so many of them refuse to pay. To worsen the situation, 22% of these borrowers are the so-called subprime borrowers — those who had little income and had little hope of returning money. Banks were not afraid of lending money to them because even if they defaulted, the insurance would pay them back.

At Drexel, he designs amazing mirrors | Philadelphia Inquirer | 01/12/2009

january 2009 by daguti

Indeed it could. Eight years and numerous calculations later, Hicks is now testing a prototype mirror - for a car, not a bike - and he is in talks with a foreign manufacturer. As with the bike mirror, the rounded surface provides a wide field of view - so wide that it eliminates the dreaded, driver-side "blind spot" - yet the subtle mathematics of his design result in little or no distortion.

Fibonacci Forex Indicators

Fibonacci numbers are sequences of numbers where each successive number is the sum of the prior 2 numbers (i.e., 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc…). The Fibonacci number pattern was developed by Leonardo Fibonacci sometime around 1200
