Born on a Blue Day
"When Daniel Tammet thinks about numbers, each one has a distinct personality. Thirty-seven is lumpy, for example; four is shy. He has a rare form of autism that gives him astonishing mental powers, such as effortlessly calculating huge numbers in his head with the speed of a computer."
An interesting interview from NPR's talk of the nation. You can also read the first chapter of the book.
Firey Teaching methods
Another interesting talk of the nation interview:
"Rafe Esquith is a trail-blazing, fast-talking, fifth-grade teacher who has racked up a slew of awards for his work at a public school in Los Angeles. Ninety-two percent of the children at the school live in households below the poverty level, but Esquith's students have reached the pinnacle of academic and artistic success. His fifth-graders are already tackling high-school fare: algebra, philosophy and Shakespeare."
"Where is the Ithaca described in such detail in Homer's Odyssey? The mystery has baffled scholars for over two millennia because Homer's descriptions bear little resemblance to the modern island called Ithaki, one of the Ionian Islands off the coast of western Greece. Homer himself is thought to have lived far away in Asia Minor (western Turkey) several hundred years after the events of the Odyssey, so most experts think that he based his poem on stories he had heard of distant Ithaki. The geographical mismatch in his poems perhaps reflected his lack of familiarity with the Ionian Islands, together with the fact that he was composing a poem rather than a travel guide.
In 2003 a radical alternative was proposed. What if Homer has been right all along? What if this mismatch has occurred not because of geographical errors by the poet, but because of geological changes in the landscape? Could something unprecedented have altered the layout of these islands since the time of the Trojan War around 1200 BC?
Since 2003 an interdisciplinary project team of geologists, classicists and archaeologists has been testing this hypothesis and the results that have emerged are astonishing. We have been able to reconstruct the former layout of these islands and it provides a compelling solution to the long-established enigma of the location of Homer's Ithaca."
Homer's great epic may have more reality embedded in it than has previously been thought. In addition to perhaps finding the place here Odysseus actually is said to have lived, science working with history and literature helps us better understand our past. Additionally, it is worth noting that instead of keeping such scholarly studies to be shared by other scholars and in the journals and books, now scholars can post to blogs or web sites to gain a wider audience and also perhaps to market their findings.
