POPSMinds and myths "..Other sciences certainly do have their own myths – just think of the story of Newton and the falling apple or Archimedes leaping out of the bath following his Eureka insight. Perhaps myths just seem more prominent in psychology because we tend to talk and write about our science in terms of studies rather than facts."

POPS2300 Year Old Model Airplane Did anyone actually build a large version of this thing? Well, no one could have come this close to the real shape of flight without working on a larger scale. This little wooden model could hardly exist unless someone had worked with large, light models, or even with man-carrying versions. Archaeologists have looked in vain for a prototype. A large model light enough to fly would be too delicate to stand the ravages of 2300 years. The original -- if it ever was -- has long since joined the desert dust. Whatever form this Egyptian airplane might have taken, it has long since returned to the world of dreams and imagination from which it first came.

POPSEdison vs. Archimedes... Alph Bingham, founder of Innocentive, has been writing an extended series on this... takes time to work through, but interesting.

POPSThe Ancient Mechanics and How They Thought He also majored in astronomy as an undergraduate, and about nine years ago, feeling science-deprived, he joined a multinational research endeavor called the Archimedes Project, based at the Max Planck Institute for the History of Science in Berlin. The Archimedes team studies the history of mechanics, how people thought about simple machines like the lever, the wheel and axle, the balance, the pulley, the wedge and the screw and how they turned their thoughts into theories and principles. The textual record begins with “Mechanical Problems,” moves to Rome and then through the medieval Islamic world to the Renaissance. It ends, finally, with Newton, who described many of the basic laws of mechanics in the 18th century. By following the historical record, the Archimedes researchers have discovered that the evolution of physics — or, at least, mechanics — is based on an interplay between practice and theory.

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.

POPSEureka! A Prayer for Archimedes Archimedes wrote his manuscript on a papyrus scroll 2,200 years ago. At an unknown later time, someone copied the text from papyrus to animal-skin parchment. Then, 700 years ago, a monk needed parchment for a new prayer book. He pulled the copy of Archimedes' book off the shelf, cut the pages in half, rotated them 90 degrees.....

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."

POPSarchimedes found! these same techniques are enabling scholars to decipher some of the multitude of scraps of papyrus fragment that fill drawers of their museums. One such, a 1,500-year-old bit of papyrus written in Greek, the original language of the New Testament, contains a key passage from the Book of Revelation that is causing consternation... the “Number of the Beast,” or the sign of the anti-Christ whose coming is predicted in the book’s apocalyptic verses. Most versions of this section of the Bible give it as 666, but it is shown in this text – which pre-dates the other texts by at least a century – as 616. taken in part from james randi.
