As October, National Pizza Month, draws to a close, Flowing Data offers a rigorous examination of pizza chains across the U.S. and the relative proximity of their outlets in different areas. It’s the handiest of guides– and one to use: surely Americans can improve on last year’s statistics; surely we can do better than 251,770,000 pounds of pepperoni consumed…
As we ask for extra crushed red pepper, we might recall that it was on this date in 1937 we– the entire population of the earth– narrowly avoided (by twice the distance of the Moon… but that’s only three seconds) obliteration as the 500,000 ton asteroid/planetoid 69230 Hermes failed to collide with our planet. (In 1989, the earth had an even closer approach, but by the smaller 4581 Asclepius.)
Brian and Peter, the keepers of Plurib.us, have gifted us with perspective: Explore our solar system and its environs– planets, dwarf planets, and moons– comparing each celestial body’s size as it might appear from earth, as it is in “true” scale (as above)… and as it routinely appears n a child’s play set…

As we boldly go, we might recall that it was on this date in 1947, after 11 years of grinding and polishing, that what had begun as 20 tons of molten glass finally became a 200-inch diameter telescope lens for Cal Tech’s Mount Palomar Observatory. It was mounted in the Hale Telescope (named in honor of the late Dr. George E. Hale who had initiated the project).and was first used on February 1, 1949 to capture pictures of the Milky Way.

The Cabana Islander holds up to 6 people. Impractical in a swimming pool, it’s really only useful in a big body of water, like an ocean, where you might fall asleep and drift out to sea.
The only good thing about this $364 piece of inflatable plastic is that when you do, inevitably, wake up somewhere over the horizon, you’ve got up to five other family members or friends to eat. Just make sure you bring someone weak when you set sail for disaster, since you’ll need to conserve as much energy as possible in the process of overpowering them to eat their body.

This computer mouse hides a digital scale inside and has a little compartment to stash a tiny amount of weed. This would be more practical if a desktop computer wasn’t a big square box with a ton of empty space where you could put a full-sized scale and several ounces of weed.
Customers who bought this also bought a plastic bic lighter that you can store an even tinier amount of weed in. Who are all these customers and what are they doing with their tiny pieces of weed?

“I have a clean!” Thanks once again, capitalism, for reminding us that one of the greatest Americans in history can be reduced to a joke for a few thousand bucks. We laugh and destroy the few people willing to put their lives at stake to ensure a better future for the next generation. One day the sun will swallow the Earth, and the rest of the universe will breathe a sigh of relief.
…and the downright insulting…
“Unless your the worlds most fuckable man, you need Sure Fuck Cologne!” (sic) says the manufacturer. They also brag it “drives women into a Hot Sexual Frenzy!” If that’s true, it must smell an awful lot like having a full-time job.

As we contemplate commercial creativity, we might recall that it was on this date in 1178 that “The upper horn of the moon split in two … a flaming torch sprang up, spewing out fire, hot coals & sparks”: an asteroid or comet collided with the moon resulting in a violent explosion that created the Giordano Bruno crater.
The upper horn [of the moon] split in two. From the midpoint of the division a flaming torch sprang up, spewing out, over a considerable distance, fire, hot coals and sparks. Meanwhile the body of the Moon which was below writhed, as it were in anxiety, and to put it in the words of those who reported it to me and saw it with their own eyes, the Moon throbbed like a wounded snake. Afterwards it resumed its proper state. This phenomenon was repeated a dozen times or more, the flame assuming various twisting shapes at random and then returning to normal. Then, after these transformations, the Moon from horn to horn, that is along its whole length, took on a blackish appearance.- Gervase, Friar and Chronicle at Canterbury, who witnessed the event
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.
