Z Machine Sets Unexpected Earth Temperature Record

Why is this plasma so hot? Physicists aren't sure. What is known for sure is that the Z Machine running at Sandia National Laboratories created a plasma that was unexpectedly hot. The plasma reached a temperature in excess of two billion Kelvin, making it arguably the hottest human made thing ever in the history of the Earth and, for a brief time, hotter than the interiors of stars. The Z Machine experiment, pictured above, purposely creates high temperatures by focusing 20 million amps of electricity into a small region further confined by a magnetic field. Vertical wires give the Z Machine its name. During the unexpected powerful contained explosion, the Z machine released about 80 times the world's entire electrical power usage for a brief fraction of a second. Experiments with the Z Machine are helping to explain the physics of Solar flares, design more efficient nuclear fusion plants, test materials under extreme heat, and gather data for the computer modeling of nuclear explosions.

Why Americans Know More About The Simpsons Than The Constitution

In his 1905 dissertation for Columbia Teachers College, Elwood Cubberly—the future Dean of Education at Stanford—wrote that schools should be factories "in which raw products, children, are to be shaped and formed into finished products...manufactured like nails, and the specifications for manufacturing will come from government and industry."

Similarly, the Rockefeller Education Board—which funded the creation of numerous public schools—issued a statement which read in part:

"In our dreams...people yield themselves with perfect docility to our molding hands. The present educational conventions [intellectual and character education] fade from our minds, and unhampered by tradition we work our own good will upon a grateful and responsive folk. We shall not try to make these people or any of their children into philosophers or men of learning or men of science. We have not to raise up from among them authors, educators, poets or men of letters. We shall not search for embryo great artists, painters, musicians, nor lawyers, doctors, preachers, politicians, statesmen, of whom we have ample supply. The task we set before ourselves is very simple...we will organize children...and teach them to do in a perfect way the things their fathers and mothers are doing in an imperfect way."
