Slow news day…

As we struggle to balance “nimble” and “quick,” we might light a candle for Lucifer Calaritanus, bishop of Cagliari in Sardinia; he died on this date in 370 (according to St. Jerome; it may have been 371).  Though the status is elsewhere disputed, Lucifer is considered a saint in Sardinia, and today is his feast day.  In any case, his name– which means “bearer of light”– is a reminder that “Lucifer” had not in his life time attained its Satanic connotation.  Indeed, it was St. Jerome, in his translation of the Bible into Latin (the Vulgate) in the 390s, who made “Lucifer” synonymous with the Dark Lord… Given that Jerome was a theological antagonist of (Bishop) Lucifer, the naming may not have been altogether coincidental.

German scale-maker Kern has been in the weighing business since 1844.  To demonstrate the precision of the scientific instruments in which it now specializes, Kern has launched The Gnome Experiment.

If Earth was a perfect sphere of uniform density, then gravity would be consistent. But it’s not, which means gravity varies wherever you go. So can we chart those discrepancies using just a basic-range Kern scale?

Method

We’re shipping our Gnome Kit from scientist to scientist around the world. Join the experiment and you’ll receive:

1x Kern EWB 2.4 Scale
Pre-calibrated according to local gravity at Kern HQ, Balingen, Germany.

1x Kern Gnome
The perfect test-subject for two good reasons: Gnomes are already accustomed to travelling the world. They also originate from our homeland, Germany.

1x Lab gloves & 1 x Air duster
Important because dust or grease will reduce the accuracy of the results.

Readers can check up on results-to-date…

… and can sign up to participate, here.

As we pack our bags to move south,* we might send earthy birthday greetings to civil engineer and geodesist John Fillmore Hayford; he was born on this date in 1868.  Hayford, the father of the modern science of geodesy, made the first precise determination of the ellipsoidal shape and size of the earth.

Identical twins Camille and Kennerly Kitt are Third Degree Black Belts in Tae Kwon Do and “Distinguished Experts” in rifle marksmanship, competitive swimmers who qualified for the Junior Olympics 5 times, and actresses (in, e.g., the films Creeporia and Blacktino).  But they are surely best known as “The Harp Twins,” “the world’s only known identical twin professional harpists…. known for their remarkable duet harp arrangements of songs by artists such as Lady Gaga, Guns N’ Roses, Led Zeppelin, Metallica, Aerosmith, Bon Jovi, Pink Floyd, U2, Journey, Taylor Swift, The Cranberries, Rihanna, Coldplay, The Beatles, Britney Spears, Enya, Johnny Cash, OutKast, P!nk, Deep Purple, The Smiths, Elton John, Joy Division, and many more.”

As we are reminded that (speaking of Joy Division) it was on this date in 1980 the Ian Curtis, the band’s lead singer, committed suicide, we might also recall that this was the date, in 1972, on which the TV series Me and the Chimp came to an abbreviated end, cancelled after 19 episodes by CBS.  An early effort by Garry Marshall and Tom Miller ( who later worked together on Happy Days and Laverne And Shirley), the sitcom was built around Ted Bessell (who’d gained prominence in That Girl)… and Buttons the Chimpanzee.  It went on to rank 46th in TV Guide‘s list of “The 50 Worst TV Shows of All Time.”

The Phoenix Coyotes got an unexpected addition to their roster last Friday while battling the Nashville Predators: Somebody chucked a slimy, whiskered catfish onto the ice. A smiling puck-girl had to cart it off in her bare hands before play could resume…  Predators players are supported by an army of catfish-flinging maniacs, who may or may not catch them by noodling. The tradition began in 2002 as a response against the [Detroit] Red Wings military use of octopus. The catfish get so thick sometimes that shovels are required to scoop them off the ice…

As we remember to pack our ponchos, we might recall that it was on this date in 1875 that Oliver Lewis rode H. P. McGrath’s thoroughbred Aristides to victory in the first Kentucky Derby, at the Louisville Jockey Club. (McGrath, a gambling parlor owner who had used his profits to enter the world of horse racing, had entered two horses in the first Derby: Aristides, who was expected to be quick out of the gate and force the other horses to wear themselves out early, and Chesapeake, whom McGrath expected to be the real winner.  But Aristides took the lead early and never relinquished it, while Chesapeake never really caught up with the pack. Not sure what to do, Aristides’s jockey, Lewis, looked to McGrath, and McGrath signaled for him to go on.  Aristides won by a long length, and took the purse — a whopping $2850.)

As we check in to Hilbert’s Hotel, we might spare a thought for Joesph Fourier; the French mathematician, physicist, Egyptologist and administrator who died on this date in 1830. Fourier introduced Jean-Francois Champollion to the Rosetta Stone, which Champollion subsequently decoded/translated.  And after calculating that a body the size of earth, at earth’s distance form the sun, should be cooler than our world is, discovered what we now call “the greenhouse effect.”  But Fourier is best remembered for his contributions to mathematical physics through his Théorie analytique de la chaleur (1822; The Analytical Theory of Heat), which introduced an infinite mathematical series to aid in solving conduction equations. (The technique allowed the function of any variable to be expanded into a series of sines of multiples of the variable– now known as “the fourier series.”)

True greatness is when your name is like ampere, watt, and fourier—when it’s spelled with a lower case letter.

- Richard Hamming (in a 1986 Bell Labs Colloquium)
