The Water Delivery Man Problem

Optimal route for the 33-city traveling salesman problem in the 1962 Car 54 contest. Proctor & Gamble sponsored a $10,000 grand prize for the winning entry. Mathematicians Robert Karg and Gerald Thompson tied for first place.

There is a problem that has vexed mathematicians for the greater part of the past century. Currently, there is no solution, and nobody knows for certain whether or not one exists. But cracking the code would be a huge breakthrough both in theoretical mathematics and practical everyday applications. Ellis Robinson brings the story, starting with a description of the problem from physicist Eddie Farhi.

Study: River Forecasting in Rockies Needs Dusting

Dust on snow is easily visible to human eyes. And Satellites too. Burgess-Bryant is involved in a project that assesses dustfall on snowpack using satellite imagery.

Snow in the Upper Colorado River Basin provides water for seven states.  Farmers, factories, and families alike depend on this water, and a considerable amount of effort goes into understanding and forecasting how much melt is going to come from the snowpack, and when.

Geoengineering: The Technological Fix to Climate Change?

Schematic showing the major geoengineering strategies in the scientific literature. Among those discussed in this piece are aerosols in the stratosphere and iron fertilization of the oceans.

You may have missed it, but last week national headlines read, “the CIA wants to control the weather.”  Those headlines came on the heels of the media learning the CIA was funding a report on geoengineering. It’s an idea that’s akin to a man-made thermostat for the globe.  Aspen Public Radio’s Science Reporter explains what geoengineering is, why you need to know about it, and why the CIA is involved.

Earth #Photobombed Saturn Last Time. Today, it's a #Selfie.

Earth-moon system as photographed by NASA spacecraft Cassini. "The Day Earth Smiled" was taken from approximately 900 million miles away on July 19, 2013.

A billion miles from the Roaring Fork Valley, there’s a satellite orbiting Saturn. This afternoon, from that planet’s shadow, the NASA space probe will take a historic photograph of Earth.  It’s the first time people down here will know exactly when the earth is going to get its picture taken... and they can look up at the cosmos and smile. Ellis Robinson has the story.

  UPDATE (July 22, 9:01 AM): The Friday July 19, 2013 photograph of the earth and our moon, taken by Cassini, was released this past weekend.
