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.

POPSπ Pi(π) appears where you least expect it. Coincidentally, Pi Day is also the birthday of Albert Einstein, who no doubt knew more than a little about pi. Pi Day celebrants, usually children with an enthusiastic teacher and a varying degree of personal interest in the subject, learn about pi, circles, and, if they're lucky, eat baked pies of various sorts.

POPSBrave New World of Digital Intimacy 
It is easy to become unsettled by privacy-eroding aspects of awareness tools. But there is another — quite different — result of all this incessant updating: a culture of people who know much more about themselves. Many of the avid Twitterers, Flickrers and Facebook users I interviewed described an unexpected side-effect of constant self-disclosure. The act of stopping several times a day to observe what you’re feeling or thinking can become, after weeks and weeks, a sort of philosophical act. It’s like the Greek dictum to “know thyself,” or the therapeutic concept of mindfulness. (Indeed, the question that floats eternally at the top of Twitter’s Web site — “What are you doing?” — can come to seem existentially freighted. What are you doing?) Having an audience can make the self-reflection even more acute, since, as my interviewees noted, they’re trying to describe their activities in a way that is not only accurate but also interesting to others: the status update as a literary form.

POPSEvolution of the Olympic Torch The 2008 Beijing Olympic torch can reportedly withstand winds of up to 40 miles an hour (65 kilometers an hour), partly due to the flat top of its Chinese-scroll-based design, according to engineer Richard Kelso.The exterior of the torch is made of aluminum-magnesium alloy and is decorated with 56 swirling clouds, one for each of China's ethnic groups.<<

POPSWhy is pleasure so suspicious? "The best sort of life, says Epicurus, is one that is free from pain in the body and from disturbance in the mind. That sounds a rather negative credo for a 21st-century devotee of the good life. Were he writing self-help books today, Epicurus would probably acknowledge that you can aim a little higher than that. He might point out in his own defence that health and peace are essential preconditions of happiness, and are easy to belittle if you are lucky enough to have them. But perhaps his most useful observation for the discerning hedonists of today, when such an intoxicating variety of gratifications are dangled before them, is a reminder of caveat emptor: "No pleasure is in itself evil, but the things which produce certain pleasures entail annoyances many times greater than the pleasures themselves."

POPSAll-girl fish that hasn't had sex for 70,000 years According to the report in the BMC Evolutionary Biology journal, one theory is that the fish may occasionally be taking some of the DNA from the males that trigger reproduction, in order to refresh their gene pool. Dr Laurence Loewe, of the university's School of Biological Sciences, said: "What we have shown now is that this fish really has something special going on and that some special tricks exist to help this fish survive. "Maybe there is still occasional sex with strangers that keeps the species alive. Future research may give us some answers."
