Qaaw What Artifact Will Tell Future Generations The Most About Us
As a symbol of the Fourth of July holiday, it is easy for the conversation this time of year to turn to iconic American flags, like the flag the
stanley thermos Marines raised at Iwo Jima; the one firefighters put up at ground zero; and the one that flew over Fort McHenry and was the inspiration for what would become our national anthem.As the space shuttle program comes to an end this week, CBS News decided to look into the flags the astronauts left behind on six trips to the moon. What s become of them CBS News correspondent Jim Axelrod reports that when Neil Armstrong and Buzz Aldrin planted the first flag on the moon, it was an ac

A U.N. treaty would not allow the U.S. or any other country to claim the moon as its territory.Smithsonian curator Allan Needell says the flags planted by the crews of all the Apollo missions that landed on the moon were goodwill gestures to the world. By and large, the symbol was very much understood for what it was, as a symbol of pride, but

An engineer on the NASA team that designed the first flag to go to the moon, Moser was told to keep it hush-hush. It was not a military, Department of Defense secret. It was just the fact that politically we didn t want the word out before the event happened, Moser says.From the beginning, there were technical problems.

Sitting at a red light can feel torturously long, but yellow lights often seem suspiciously short. It not all in your head: some yellow lights are too short. There is an ideal minimum length o
stanley taza f a yellow traffic light. You just might never experience it especially if you ;re from Chicago . There no universal correct yellow traffic light time, since people going 35 MPH will be able to stop quicker than pe
stanley cup ople going 50 MPH. But there are equations to figure out the minimum safe time for a yellow light. The speed limit obviously matters, but so does how quickly a car can decelerate, and whether the road is hilly or level. Plus, you have to account for the driver perception reaction time, which is basically how quickly a driver can react to seeing the light turn yellow. And that reaction time can vary from person to person, which is where things get sticky. That why a lot of cities are adopting equations to figure out how to set their traffic lights instead of deciding on one uniform time per speed zone. According to a 2012 survey of 200 transportation agencies in the U.S., Canada, and Germany, 40% of the agencies use an e

It a much better system than just picking one time per speed zone, the current Chicago method. Yellow lights were shortened to 3 seconds in 30 MPH zones there, and results have prompted plenty of anger, especial
