Sunspots 261

Things I have recently spotted that may be of interest to someone else:



Science:Entanglement (the notion that two originally closely connected particles can somehow remain connected when separated across long distances) is one of the many weird aspects of quantum mechanics. Wired reports that some scientists believe that this property may allow migrating birds to see magnetic fields.

Wired also reports that scientists who have studied fights between ravens say that the birds can act as if they are consoling the losers.

Politics:
(or Education) A New York Times book review (you may need to obtain a free password to read this periodical) says that Diane Ravitch, once Assistant Secretary of Education under President George H. W. Bush, and a strong advocate of school choice and of standardized testing as a measuring instrument, has written a book in which she now says that neither school choice nor standardized tests have done much, if any, good.
