Atomic Goal - 800 Years of Power From Waste
Matthew Ryan Williams for The New York Times Ted Ellis of TerraPower working on a fuel system. Matthew Ryan Williams for The New York Times Ash Odedra, wearing glasses, the principal design engineer at TerraPower in Bellevue, Wash., a company that is being led by Bill Gates and Nathan Myhrvold, a fellow Microsoft billionaire. The quest is for a new kind of nuclear reactor that would be fueled by today’s nuclear waste, supply all the electricity in the United States for the next 800 years and, possibly, cut the risk of nuclear weapons proliferation around the world.

This article isn’t entirely about productivity, but I guarantee you’ll learn a thing or two. Here are 100 incredible things I learned watching 70 hours of TED talks last week!
Cool math trick: Converting between miles and kilometers
The Fibonacci sequence is made up of numbers that are the sum of the previous two numbers in the sequence, starting with 0 and 1. It's 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144… 1 is 0+1, 2 is 1+1, 3 is 1+12, 5 is 2+3, and 8 is 3+5. The number after 144 is 233, or 89+144. The Fibonacci number describes the golden spiral, an ideal form much beloved by designerseverywhere. Interestingly, it also neatly matches the relationship between kilometers and miles.
Inconsistent Mathematics, Reutersvärd, and Buddhism: An Interview with Chris Mortensen
Inconsistent Mathematics, Reutersvärd, and Buddhism: An Interview with Chris Mortensen by Michael Lopresto Chris Mortensen is Emeritus Professor of Philosophy at the University of Adelaide. He thinks that the inconsistent hasn't been taken seriously enough in Western philosophy, that the masterpieces of Reutersvärd rub our noses in the inconsistent, and that Western philosophy and Buddhism are complementary. He's the author of Inconsistent Mathematics (1995) and Inconsistent Geometry (2010). Firstly, what made you get into philosophy?

Jeremy Howard: The wonderful and terrifying implications of computers that can learn
What happens when we teach a computer how to learn? Technologist Jeremy Howard shares some surprising new developments in the fast-moving field of deep learning, a technique that can give computers the ability to learn Chinese, or to recognize objects in photos, or to help think through a medical diagnosis. (One deep learning tool, after watching hours of YouTube, taught itself the concept of “cats.”) Get caught up on a field that will change the way the computers around you behave … sooner than you probably think. This talk was presented to a local audience at TEDxBrussels, an independent event.

Unhappy Truckers and Other Algorithmic Problems - Issue 3: In Transit
When Bob Santilli, a senior project manager at UPS, was invited in 2009 to his daughter’s fifth grade class on Career Day, he struggled with how to describe exactly what he did for a living. Eventually, he decided he would show the class a travel optimization problem of the kind he worked on, and impress them with how fun and complex it was. The challenge was to choose the most efficient route among six different stops, in a typical suburban-errands itinerary. The class devised their respective routes, then began picking them over. But one girl thought past the question of efficiency. “She says, my mom would never go to the store and buy perishable things—she didn’t use the word perishable, I did—and leave it in the car the whole day at work,” Santilli tells me.

David Epstein: Are athletes really getting faster, better, stronger?
When you look at sporting achievements over the last decades, it seems like humans have gotten faster, better and stronger in nearly every way. Yet as David Epstein points out in this delightfully counter-intuitive talk, we might want to lay off the self-congratulation. Many factors are at play in shattering athletic records, and the development of our natural talents is just one of them. This talk was presented at an official TED conference, and was featured by our editors on the home page.
