Among the moon’s vast riches: gold, cobalt, iron, palladium, platinum, tungsten and Helium-3, a gas that can be used in future fusion reactors to provide nuclear power without radioactive waste. “We went to the moon 50 years ago, yet today we have more computing power with our iPhones than the computers that sent men into space,” Jain said. “That type of exponential technological growth is allowing things to happen that was never possible before.”

We old pilots were drilled to know what is the closest airport of safe harbor while in cruise. Airports behind us, airports abeam us, and airports ahead of us. They’re always in our head. Always. If something happens, you don’t want to be thinking about what are you going to do–you already know what you are going to do. When I saw that left turn with a direct heading, I instinctively knew he was heading for an airport. He was taking a direct route to Palau Langkawi, a 13,000-foot airstrip with an approach over water and no obstacles. The captain did not turn back to Kuala Lampur because he knew he had 8,000-foot ridges to cross. He knew the terrain was friendlier toward Langkawi, which also was closer.

The problem arose when planners made blanket decisions, applying the criteria of speed and efficiency to all streets. Distances between points of interest grew, parking lots occupied valuable real estate, and Main Street disappeared as the automobile, not the pedestrian, became the “owner” of the street. It has become so prevalent, that much of modern planning today is aimed at reformatting these streets from the scale of the automobile back to the scale of the pedestrian.

When a street is shared, all users of the street must have a heightened sense of situational awareness. The requirement for every user of the street to be situationally aware will lead to caution and therefore safety. Designated lanes reduce the need for this situational awareness, providing people with a false sense of security while in their lane. Streets designed to demand situational awareness may not be the easiest, nor the fastest means to travel, but provide a safer environment for every mode of transportation on the street.
Stewart’s most powerful critiques result from his juxtaposing clips of politicians and commentators on news broadcasts to demonstrate their hypocrisy. He’ll contrast a clip of a Fox News commentator expressing outrage at President Obama taking a particular action with a clip of the same commentator praising President Bush for taking a similar same action. Stewart also uses montages of clips from CNN and other news networks to demonstrate their simultaneously sensationalistic and superficial coverage of disasters and trials. But for fair use, Stewart’s rebroadcast of these clips would be willful copyright infringement, subject to statutory damages of up to $150,000 per clip.
