In his 60s, having suffered a series of heart attacks, Marconi dreamed “of a device that would let him hear lost sounds, let him tap into these eternal frequencies. He would tell people that if he got it right, he could hear Jesus of Nazareth giving the Sermon on the Mount…”
At the end of his life he could sit in his piazza in Rome, and hear everything that was ever said to him or about him. He could relive every toast and testimonial. And we all could — hear everything: Hear Caesar. Hear Shakespeare give an actor a line-reading. Hear my grandmother introduce herself to my grandfather at a nightclub in Rhode Island. Hear someone tell you that they love you, that first time they told you they loved you. Hear everything, forever.
There’s more in Rebecca Rosen’s appreciation at The Atlantic, “The Museum of Lost Sounds,” where she links to the Cornell Ornithology Lab’s sound archive. You can hear the whole of DiMeo’s Marconi piece, “These Words, Forever,” here, and more of his wonderful podcasts at The Memory Palace.
After we candle our ears, we might send both birthday greetings and notes of condolence to Johannes Hevelius; he was born on this date in 1611, and died on this date in 1687. A councilor and mayor of Danzig (Gdańsk), Hevelius was an avid– and important– astronomer who worked from observatories he built across his city’s rooftops. From four years’ telescopic study of the Moon, he compiled Selenographia (“Pictures of the Moon”, 1647), an atlas of the Moon with some of the earliest detailed maps of its surface. A few of his names for lunar mountains (e.g., the Alps) are still in use, and a lunar crater is named for him. In Prodromus Astronomiae (1690), Hevelius catalogued 1564 stars, discovered four comets, described ten new constellations (seven of which are still recognized by astronomers), and was one of the first to observe the transit of Mercury.
Readers may feel a sense of relief now that the Mayan prophecy of doom in 2012 has gone unfulfilled– understandable… but maybe a bit premature. As this handy reference from The Economist illustrates…
…while most of the major prophecies on record are past their due dates (the Norse and Nostradamus were canny enough to refrain from specifying exact timings), one apocalyptic alert is still active… and sadly for humankind, it’s from an all-too-august source.
Possibly the greatest and most influential scientist in history, Isaac Newton was also a pious, albeit unorthodox, Christian. Early in his life, surrounded by the Plague, the Great Fires of London, and assorted other upheavals, Newton decided that the End Times were at hand. But while Newton realized promptly that he was premature, millennial pronouncements continued from others. So, in a 1704 manuscript (in which he describes his attempts to extract scientific information from the Bible) he estimated that the world would end no earlier than 2060. He explained: “This I mention not to assert when the time of the end shall be, but to put a stop to the rash conjectures of fanciful men who are frequently predicting the time of the end, and by doing so bring the sacred prophesies into discredit as often as their predictions fail.”
Now, “no earlier than 47 years from now” gives one some time to prepare.
But could it be that even Sir Isaac made mistakes? So argues David Flynn, author of Temple at the Center of Time: Newton’s Bible Codex Deciphered and the Year 2012. Flynn revisits Newton’s logic and his calculations, and “corrects” it to find that the threshold for total termination may be much nearer– indeed, this year– 2013… Read the story at WND.com, along with “Just the Facts: How Satan Takes ‘Legal Authority’ Over You” and “Obama Staged Sandy Hook Massacre.”
As we contain our credulity, we might send cosmic birthday greetings to Robert Woodrow Wilson; he was born on this date in 1936. An astronomer, Wilson and his Bell Labs partner, physicist Arno Penzias, discovered the cosmic microwave background radiation (CMB) in 1964– a feat that earned them the Nobel Prize (in 1978), as CMB was a critical corroborator of the Big Bang Theory of the origin of the universe.
Nearly 40 years ago, a Hungarian architecture professor, Emo Rubik, created a puzzle to use with his design students- a puzzle with 43 quintillion possible combinations and one solution. Within five years, it had been played by over 20% of the world’s population, and has so far sold over 350 million units (not counting “unofficial” versions).
As we twist and turn, we might spare a thought for Ulugh Beg; he died on this date in 1449. Probably Mongolia’s greatest scientist, Beg was a Timurid ruler and sultan, a mathematician, and the greatest astronomer of his time. In his observatory in at Samarkand he discovered a number of errors in the computations of the 2nd-century Alexandrian astronomer Ptolemy, whose figures were still being used; his star map (of 994 stars) was the first since Hipparchus’.
One could be forgiven for mistaking these structures for the set of science fiction epic staged on a planet light years from Earth. In fact, they are centuries-old scientific instruments, designed and used in Jantar Mantar (Jaipur), India, to explore the heavens. They were built by a great Maharaja in the early decades of the 18th century and they have been in continuous use since.

As we raise our eyes, we might send celestial birthday greetings to Mary Watson Whitney; she was born on this date in 1847. A protege of astronomer Maria Mitchell, Whitney followed her mentor as professor of astronomy at Vassar and as head of the Observatory there. A champion of scientific education for women, Whitney built Vassar’s astronomy program into one of the nation’s finest.
As a service to bewildered younger viewers of the recent Grammy Awards show, the History Channel and Twitter combined (under the auspices of Funny or Die) to produce the helpful documentary, Who is Paul McCartney?
As we say, “oh yeah (yeah yeah),” we might send heavenly birthday greetings to Renaissance astronomer Nicolaus Copernicus; he was born on this date in 1473. Copernicus’ De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres; published just before his death in 1543), with its heliocentric account of the solar system, is often regarded as the beginning both of modern astronomy and of the scientific revolution.
Of all discoveries and opinions, none may have exerted a greater effect on the human spirit than the doctrine of Copernicus. The world had scarcely become known as round and complete in itself when it was asked to waive the tremendous privilege of being the center of the universe. Never, perhaps, was a greater demand made on mankind – for by this admission so many things vanished in mist and smoke! What became of our Eden, our world of innocence, piety and poetry; the testimony of the senses; the conviction of a poetic – religious faith? No wonder his contemporaries did not wish to let all this go and offered every possible resistance to a doctrine which in its converts authorized and demanded a freedom of view and greatness of thought so far unknown, indeed not even dreamed of.
