Humpback Whale Breaching II wallpaper
There is a nice write up and video about whales and their evolution from land mammals to sea mammals at PBS.
In 1978, paleontologist Phil Gingerich discovered a 52-million-year-old skull in Pakistan that resembled fossils of creodonts — wolf-sized carnivores that lived between 60 and 37 million years ago, in the early Eocene epoch. But the skull also had characteristics in common with the Archaeocetes, the oldest known whales. The new bones, dubbed Pakicetus, proved to have key features that were transitional between terrestrial mammals and the earliest true whales
We all make mistakes. I was under the impression that the gossip/newest urban myth about China drilling for oil off the coast of Florida was so absurd that it wouldn’t gain any traction, but some people keep repeating it, The Three Biggest Myths About Offshore Drilling
Conservatives from Rudy Giuliani to Dick Cheney have repeatedly claimed that the United States needs to start drilling for off-shore oil because China is taking “American oil” off the coast of Cuba, just “60 miles off the coast of Florida.”
Cheney exhorted, “Even the communistshave figured out that a good answer to high prices is more supply.” That same day, Rep. Roy Blunt (R-MO) wrote that Castro was allowing drilling “45 miles from the Florida keys.”
Rep. George Radanovich (R-CA) and House Minority Leader John Boehner (R-OH) have also raised the specter of Chinese drilling just off U.S. shores. However, this modern invocation of the Red Scare the claim is completely false.
As Cheney was forced to acknowledge, “no Chinese firm is drilling” off Cuba’s coast. Talking Points Memo has recorded the large number of conservatives hyping the false story
is this like the grown-ups version of having an imaginary friend.
Advance brings low-cost, bright LED lighting closer to reality. The Cliff notes version. LED lights expensive because of substrate. Scientists create silicon coated substarte that is sheaper and does the same thing as sapphire LEDs. Oops zirconium nitride is unstable in the presence of silicon. Scientist discover that a layer of aluminum nitride solves that problem. The silicon substarte will allow for the unscaling of production which will also bring down costs. Two years before this all hits the market and consumers get the benefit of the energy savings from using LEDs for lighting.
