POPSAncient Blueprints of Calculus Uncovered in Archimedes Text Details have been released from the nine-year-long reconstruction project to recover the Greek mathematician's writings from this one-of-a-kind find and the results are fascinating. Buried beneath the surface of this gilded palimpsest, researchers discovered more extensive demonstrations of concepts such as infinite series, approximations, limits, and integral calculus than had been known to exist in ancient times. Archimedes wrote The Method almost two thousand years before Isaac Newton and Gottfried Wilhelm von Leibniz developed calculus in the 1700s. Reviel Netz, an historian of mathematics at Stanford University who transcribed the text, says that the examination of Archimedes' work has revealed "a new twist on the entire trajectory of Western mathematics."

POPSThe 10 Weirdest Facts about American Presidents 7. Calvin Coolidge, the 30th president, was reported to be a very interesting character. When not having his head massaged with Vaseline during breakfasts in bed or riding his own mechanical bull, he was ringing the White House doorbell and then running off to hide. 8. So far, all American presidents have claimed ancestry limited to one or more of just seven nationalities: Dutch, English, German, Irish, Scottish, Swiss, and Welsh. 9. Grover Cleveland was the only president to openly admit that he had fathered an illegitimate child. 10. There were four presidents who were not actual presidents of the United States: Sam Houston, Mirabeau Lamar, and Anson Jones were all presidents of the Republic of Texas. Jefferson Davis was President of the Confederate States of America.

POPSCaral: The first city in the New World A brief article on a stunning archaeological discovery in South America. About six years ago, Peruvian/American archaeologist Ruth Shady , introduced the "oldest city in America" to the world. It was Caral; an ancient city on the Pacific coast of Peru, with trade centers, temples and a pyramid complex not less impressive than its counterparts in Mexico and Guatemala. The most exciting thing about Caral was its age: The city was carbon dated to ca. 3000 BCE, which strongly suggested a radical change in history textbooks. All evidence show Caral was not an exception in the region and there are many more ancient towns, waiting to be discovered. Another interesting thing about Caral is, its surprisingly peaceful social order. Archaeologists found no city walls, no forts, no signs of an army and even not a single weapon in Caral. Once again, thanks to Ruth Shady for this fantastic discovery.

POPSIs Time disappearing from the universe? At an everyday level, the change would not be perceptible. However, it would be obvious from cosmic scale measurements tracking the course of the universe over billions of years. The change would be infinitesimally slow from a human perspective, but in terms of the vast perspective of cosmology, the study of ancient light from suns that shone billions of years ago, it could easily be measured Difficult to fathom.

POPSBefore the Big Bang - the Big Bounce Now, however, Dr Bojowald and fellow physicists are exploring territory unknown even to Einstein - the time before the Big Bang - using his new theory, called Loop Quantum Cosmology. An analysis of this, one of a series of newly-emerging theories which combine Einstein's theory of gravity (general relativity) with that of the subatomic world (quantum theory), "is supposed to provide a non-singular framework in which one could address the question of what was there before the Big Bang," he says.

POPSEarth's Magnetic Field Reversal is Approaching Here is another reason why humanity seems to lose direction.... :-) "Right now, historic records show that the strength of the magnetic field is declining very rapidly. From a quick back-of-the-envelope prediction, in 1,500 years the field will be as weak as it's ever been and we could go into a state of polarity reversal," says Singer. "One broad goal of our research is to provide some predictive capability for what could happen and what could be the signs of the next reversal."
