Hot Springs At Yellowstone Changed Their Color Due To Tourist Activity 18

Posted by samzenpus

An anonymous reader writes Researchers say that the different colors of the hot springs in Yellowstone National Park are caused by human contamination. From the article: "Researchers at Montana State University and Brandenburg University of Applied Sciences in Germany have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park's hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus. If Yellowstone National Park is a geothermal wonderland, Grand Prismatic Spring and its neighbors are the ebullient envoys, steaming in front of the camera and gracing the Internet with their ethereal beauty. While the basic physical phenomena that render these colorful delights have long been scientifically understood—they arise because of a complicated interplay of underwater vents and lawns of bacteria—no mathematical model existed that showed empirically how the physical and chemical variables of a pool relate to their optical factors and coalesce in the unique, stunning fashion that they do."

People want consistent UI.

Maybe they do. But what they need is an appropriate one.

Having to have a muli-touch smartphone GPS and a button and dial tactile GPS in the car seems stupider than you assert touchscreen in a car is.

It's not stupid because they're used in different situations.

+ - Librarians: The Google Before Google

An anonymous reader writes "NPR has an article about the questions people ask librarians. Before the internet, the librarian was your best bet for a quick answer to anything on your mind. "We were Google before Google existed," NYPL spokesperson Angela Montefinise explains. "If you wanted to know if a poisonous snake dies if it bites itself, you'd call or visit us." The New York Public Library in Manhattan recently discovered a box of old reference questions asked by patrons and plans to release some in its Instagram account. Here are a few of the best:
  • I just saw a mouse in the kitchen. Is DDT OK to use? (1946)
  • What does it mean when you dream of being chased by an elephant? (1947)
  • Can you tell me the thickness of a U.S. Postage stamp with the glue on it? Answer: We couldn't tell you that answer quickly. Why don't you try the Post Office? Response: This is the Post Office. (1963)
  • Where can I rent a beagle for hunting? (1963)

Never tell people how to do things. Tell them WHAT to do and they will surprise you with their ingenuity. -- Gen. George S. Patton, Jr.
