Ten years in, nobody has come up with a use for blockchain. The Art of Learning Summary - Deconstructing Excellence. The Art of Learning Summary Josh Waitzkin’s story is a fascinating one, culminating in a book that surpasses any other writing in its insight into how a world champion is made. Everyone in the chess world knew the name Josh Waitzkin by the time he earned the Chess Master designation at the age of twelve, somewhere in the middle of his eight national championship titles. Notoriety in the chess world then morphed into pop culture fame five years later with the movie Searching for Bobby Fischer, which was based on Waitzkin’s life. In seeking an escape from the inner turmoil caused by his child celebrity status, Josh stumbled upon the Tao Te Ching, and was drawn by the Buddhist and Taoist philosophies of inner tranquility.

The journey from king of the chess nerds to martial arts legend is astounding in itself, but the real story here is that Josh subsequently accomplished what few have done. Part I: The Foundation Chapter 1: Innocent Moves & Chapter 2: Losing to Win Dr. Part II: My Second Art. How to Study and Learn (Part One) All thinking occurs within, and across, disciplines and domains of knowledge and experience, yet few students learn how to think well within those domains.

Despite having taken many classes, few are able to think biologically, chemically, geographically, sociologically, anthropologically, historically, artistically, ethically, or philosophically. Students study literature, but do not think in a literary way as a result. They study poetry, but do not think poetically. They do not know how to think like a reader when reading, nor how to think like a writer while writing, nor how to think like a listener while listening. Consequently they are poor readers, writers, and listeners. To study well and learn any subject is to learn how to think with discipline within that subject. To become a skilled learner is to become a self-directed, self-disciplined, self-monitored, and self-corrective thinker, who has given assent to rigorous standards of thought and mindful command of their use. Inceptionism: Going Deeper into Neural Networks. Posted by Alexander Mordvintsev, Software Engineer, Christopher Olah, Software Engineering Intern and Mike Tyka, Software EngineerUpdate - 13/07/2015Images in this blog post are licensed by Google Inc. under a Creative Commons Attribution 4.0 International License.

But even though these are very useful tools based on well-known mathematical methods, we actually understand surprisingly little of why certain models work and others don’t. So let’s take a look at some simple techniques for peeking inside these networks. We train an artificial neural network by showing it millions of training examples and gradually adjusting the network parameters until it gives the classifications we want. Why is this important?

An Interactive Guide To The Fourier Transform. The Fourier Transform is one of deepest insights ever made. Unfortunately, the meaning is buried within dense equations: Yikes. Rather than jumping into the symbols, let's experience the key idea firsthand. Here's a plain-English metaphor: What does the Fourier Transform do? Here's the "math English" version of the above: The Fourier Transform takes a time-based pattern, measures every possible cycle, and returns the overall "cycle recipe" (the strength, offset, & rotation speed for every cycle that was found). Time for the equations? If all goes well, we'll have an aha! This isn't a force-march through the equations, it's the casual stroll I wish I had. From Smoothie to Recipe A math transformation is a change of perspective.

The Fourier Transform changes our perspective from consumer to producer, turning What did I see? In other words: given a smoothie, let's find the recipe. Why? So... given a smoothie, how do we find the recipe? Well, imagine you had a few filters lying around: Whoa. Oh! Einstein’s Intuition : Quantum Space Theory.

Thinking like a Genius. Thinking and recall series Problem solving: creative solutions "Even if you're not a genius, you can use the same strategies as Aristotle and Einstein to harness the power of your creative mind and better manage your future. " The following strategies encourage you to think productively, rather than reproductively, in order to arrive at solutions to problems. "These strategies are common to the thinking styles of creative geniuses in science, art, and industry throughout history. " Nine approaches to creative problem solving: Rethink!

Look at problems in many different ways. Exercise #2 illustrates how famous thinkers used these approaches. Exercise #1: illustrates applications of the nine approaches.

"Last week, I jokingly asked a health club acquaintance whether he would change his mind about his choice for president if presented with sufficient facts that contradicted his present beliefs. He responded with utter confidence. "Absolutely not," he said. "No new facts will change my mind because I know that these facts are correct. " I was floored. In his brief rebuttal, he blindly demonstrated overconfidence in his own ideas and the inability to consider how new facts might alter a presently cherished opinion. In the current presidential election, a major percentage of voters are already committed to "their candidate"; new arguments and evidence fall on deaf ears.

Perhaps the single academic study most germane to the present election is the 1999 psychology paper by David Dunning and Justin Kruger, "Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments. " -Robert Burton (Excerpt: "My Candidate, Myself," Salon.com, 9.22.08. Keywords for the Engines scripts. The Fermi Paradox: Advanced civilizations do not… This article is partly adapted from my TransVision 2007 presentation, “Whither ET? What the failing search for extraterrestrial intelligence tells us about humanity's future.”

As I stated in my previous article, “The Fermi Paradox: Back with a vengeance”: The fact that our Galaxy appears unperturbed is hard to explain. We should be living in a Galaxy that is saturated with intelligence and highly organized. Thus, it may be assumed that intelligent life is rare, or, given our seemingly biophilic Universe, our assumptions about the general behaviour of intelligent civilizations are flawed.A paradox is a paradox for a reason: it means there’s something wrong in our thinking. So, let’s try to figure out what’s going on. …advertise their presence to the local community or engage in active efforts to contact As SETI is discovering (but is in denial about), space is not brimming with easily detectable radio signals.

Centre for Learning & Performance Technologies The Library Top down implementation of social learning won't work It's time to encourage people to use public social media tools - not ban them! What is social learning? An explanation using Twitter I was taking a look at all the resources that I had collected during 2008 in my Library as well as those that I had posted about in my blogs, etc, to identify those that I particularly enjoyed, that inspired me, made me think and/or I just found useful.

There were many, but I finally narrowed my list down to 100 (see below). I then fed all the titles into Wordle to generate a word cloud and identify trends in this collection of my favourite resources. Here are the resources listed chronologically by the month in which they appeared. 13 tips for virtual world teaching , Matt Villano, Campus Technology Thanks to YouTube, professors are finding more audiences , Jeffrey R Young, Chronicle of Higher Education What happened to performance support? List of cognitive biases. Systematic patterns of deviation from norm or rationality in judgment The loss aversion cognitive bias has been shown in monkeys Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment.

They are often studied in psychology and behavioral economics.[1] Although the reality of most of these biases is confirmed by reproducible research,[2][3] there are often controversies about how to classify these biases or how to explain them.[4] Gerd Gigerenzer has criticized the framing of cognitive biases as errors in judgment, and favors interpreting them as arising from rational deviations from logical thought.[5] Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior.

Social biases[edit] See also[edit] [edit] The Size Of Our World. A genius explains | From the Guardian. Daniel Tammet is talking. As he talks, he studies my shirt and counts the stitches. Ever since the age of three, when he suffered an epileptic fit, Tammet has been obsessed with counting. Now he is 26, and a mathematical genius who can figure out cube roots quicker than a calculator and recall pi to 22,514 decimal places. He also happens to be autistic, which is why he can't drive a car, wire a plug, or tell right from left. He lives with extraordinary ability and disability. Tammet is calculating 377 multiplied by 795. Tammet is a "savant", an individual with an astonishing, extraordinary mental ability. There are many theories about savants. Scans of the brains of autistic savants suggest that the right hemisphere might be compensating for damage in the left hemisphere. Tammet is creating his own language, strongly influenced by the vowel and image-rich languages of northern Europe.

Tammet is softly spoken, and shy about making eye contact, which makes him seem younger than he is. Geometric double-meanings. Jen-chung Chuan Department of Mathematics National Tsing Hua University Hsinchu, Taiwan 300 jcchuan@math.nthu.edu.tw Introduction Why is a geometric figure important? A geometric figure clarifies a theorem, motivates a proof, stimulates the thinking process, sums up a lengthy animation, provides a counterexample to a wild conjecture, or just plainly announces the existence of a significant piece of mathematics. Why is a geometric figure interesting? It is interesting often because it carries double meanings. "Given" and "To Construct" Switched A geometric construction problem has three parts: "Given", "To Construct", and the construction itself.

By switching the "Given" and the "To Construct" parts, we see that the picture may have these two interpretations: This tiny example shows that dynamic geometry is at least twice as interesting as the traditional one. The picture carries two messages: Evolute and Involute Involute is the path of a point of a string tautly unwound from the curve.

(Note you must enter the year as a 4-digit number!) The Days (And Years) Of Our Lives Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. The earth is in motion. The top-like rotation of the earth on its axis is how we define the day. The revolution of the earth around the sun is how we define the year. We all learn in grade school that the planets move at differing rates around the sun. Why the huge differences in periods? Johannes Kepler Tycho Brahe Kepler briefly worked with the great Danish observational astronomer, Tycho Brahe.

Here you see a planet in a very elliptical orbit. Kepler's third law is the one that interests us the most. Let's just solve for the period by taking the square root of both sides: Isaac Newton.
