num8er5 (10. 974)

Via Web Curios (much more to explore on the weekly roundup), we are directed towards an list of the first ten-thousand digits as indexed by Erich Friedman with a distinguishing fact for each that makes the number special. Among the new and revisited concepts we learned about our favourites were seventeen possible wallpaper groupings that can cover a plane with an indefinitely repeating motif—patterns often found in textiles and tessellations, Mersenne Primes, the weird sequence in the eight thousand nine hundred and seventies that all equal 8 + 9⁴ + 7⁴ + n and Narcissistic Numbers, like 153 (=1³+5³+3³) which may be amusing for amateurs and in puzzles (see also) but hold no mathematical significance.

human computer (10. 817)

Despite a posthumous and four-decade late official acknowledgement by the world records authority, Shakuntala Devi (เฒถเฒ•ುಂเฒคเฒฒಾ เฒฆೇเฒตಿ), nonetheless a celebrated author, mental calculator, political opponent to Indira Ganhdi in parliamentary elections after her prime-ministership and astrologer—without any formal education (though born into the Brahmin caste her father was a circus performer, a trapeze artist and lion tamer before taking his prodigious daughter on tour), achieved her record setting calculation on this day in 1980 at Imperial College, London, multiplying two randomly-generated thirteen digit numbers in under half-a-minute, rivalling the processing times of contemporary computers. In addition to authoring several books on arithmetic to teach people some of her methods for simplifying and intuiting solutions, including Figuring: The Joy of Numbers, Devi also wrote several cookbooks, crime novels and a rather controversial though suppressed and not widely and first study on homosexuality in India (which possibly delayed recognition by Guinness), written in order to understand her gay husband and to better understand the community.

platonic solids (10. 769)

Via tmn, we are directed to a 1974 installation by collector, curator and conceptual artist Sol LeWitt’s serial exploration of negative and positive space, both flat and realised in three-dimensions, in his one hundred-twenty-two permutations of how a cube could be not closed space. This matrix of deconstruction invites one to reexamine the fundamentals of geometry and perspective that we otherwise might take for granted.

beflix (10. 736)

Via Waxy, we a directed to this thoroughgoing study of early computer art of the 1950s and 1960s by Amy Goodchild, beginning with the moment of inception with Babbage and Lovelace speculating on the creative potential of their difference engine to the realisation of mathematician Ben Laposky using sine functions and oscilloscopy to produce “electrical compositions” and one of the earliest interactive applications called MusiColor that generated patterns and light mapped from audio inputs. There are profiles of the pioneers in this field with images and video presentations of various pivotal works and installations as well as the above programming language for computer animation—from Bell Flicks—made for educational and engineering applications 1970 to explore, which are really remarkable considering the time and labour put into each project and makes one reflect how pace and patience temper the creative process in an age of instant iteration.

penta-vigesimal (10. 678)

Whilst mathematics is universal, there is no monopoly on notation and alternative numbering systems certainly do yield insight on cognition, computation and reckoning parallels. The Western hemisphere’s first new notational system in over a century was developed in the early 1990s, we learn via Clive Thompson’s Linkfest (previously), by a small class of middle school and high school students as part of maths enrichment project in Katovik, Alaska, noting that they didn’t have the numbers to represent all the numbers in Iรฑupiaq in Arabic-Hindi numerals alone for their base-twenty counting, scores used in Danish, French and for some other Inuit family languages), devising and refining a method of arithmetically representing all the native values reckoned on all one’s fingers and toes, with positional correspondence derived from native terms—for example, tallimat (5) coming from taliq (arm) for all of one’s five digits, iรฑuiรฑรฑaq (20) meaning a whole person or the glyph for zero or null a gesture of negation. A marked increase in scores on standardised mathematics tests for indigenous communities using notational systems that more closely match their ethnographic heritage not only helps with student achievement but demonstrates for all involved that numeracy is embedded within their culture and not something imparted by western hegemony.

♾️+1 (10. 625)

BBC Future has an interesting discussion of those middlingly large numbers, exponents upon exponents though smaller than a googol or googolplex, that are yet unnamed and yet will equally boggle the mind and that leave us overdrawn in the paper, ink and time department—still falling far short of infinity but with the reminder that some infinities are bigger than others.

native client (10. 528)

Via Clive Thompson’s latest Linkfest, not only are we directed to a collection of emulators of graphing calculators like the example pictured but are moreover educated in the method reproducing these classic interfaces using MAME (Multiple Arcade Machine Emulator, an open-source tool to re-create hardware as software, previously)—a collaborative bit of programming by Nicola Salmoria to ensure that historic coding isn’t lost to the ages and that virtual consoles can exist within all sorts of operating system and browser environments.

zero my hero (10. 507)

Turning fifty this month with its debut as a series with Multiplication Rock with songs written and performed by Bob Dorough going through the tables—see also—the interstitial animated educational shorts Schoolhouse Rock! was a staple of American Saturday morning cartoon programming, originally running through 1984. The original concept was suggested by an advertising executive of the influential firm McCaffrey and McCall’s that his young son was—despite being able to memorise the lyrics of Rolling Stones songs—struggling to rote lessons, resulting in the pre-canon “Three is a Magic Number” in 1971 before pursuing the project further. One of three between programming segments along with Time for Timer (“A Hankering for a Hunk of Cheese”) and the Bod Squad (“The Munchies,” “Don’t Drown Your Food”) and was followed by a second series, Grammar Rock, and for the US bicentennial in 1976, America Rock, culminating in the final run of Scooter Computer and Mister Chips.

ars notaria (10. 503)

Via Clive Thompson’s latest linkfest, which is a delight in itself to check in on often, we are introduced to the Cistercian system of ciphers, almost rune-like, developed by the monastic order parallel to the arrival of the Hindu-Arabic numerals in northwestern Europe which gradually replaced Roman notation, this stave system of units was far more compact and convenient for transcription as a single glyph could represent any value from one to ten-thousand. The pattern for forming higher numbers becomes apparent and later scholars expanded the system exponentially into the trillions. While seemingly not used for calculation, manuscripts from the thirteenth century show that they were used for numbering lists, indices, tables, musical notation and foliation—that is, page numbers. For more exploration and for a challenge (see also), click through to find source code to make a Cistercian clock.

innerspace (10. 307)

Designed by astrophysicist Frank Drake (see previously) with input from Carl Sagan and others as a proof-of-concept demonstration rather than an attempt to enter into to dialogue with extra-terrestrials and criticised as being too low-resolution to be recognisable to future recipients, the Arecibo Message (see also here and here) was beamed from the radio observatory in Puerto Rico on this date in 1974, aimed in the direction of the globular star cluster M13, some twenty-five thousand light-years from Earth. When encoded graphically, the some sixteen hundred bits of data produce the pictured image with seven elements, from top to bottom: the decimal system, the valance of the elements that make up DNA, the chemical formula for the constituent nucleotides, the approximate number of said organic molecules in the human genome with representation of the double-helix structure, the average dimensions of a human male plus the Earth’s population (four billion, compared to eight billion presently), a representation of the Solar System and finally in purple, the Arecibo telescope. The precise number of bits, 1 679, is a semiprime—that is, the product of two prime numbers, seventy-three and twenty-three, to prompt one toward the right orientation, the alternate arrangement producing static. An answer came in 2001 in the form of a crop circle near the Chilbolton radio telescope in Hampshire—rather intricately replacing the carbon-based DNA with silicon and the pictogram of the human figure looks alien—though this reply was unfortunately an elaborate hoax.

hubertustag (10. 268)

Fรชted on this day as the Apostle of the Ardennes and patron protector of hunters, opticians, metalworkers, mathematicians and chicken roasters, the sainted eighth century bishop of Liรจge (see previously here and here) is regarded as the originator of ethical deer stalking and preached compassion for animals as God’s creations—Hubertus himself converted whilst pursuing quarry in the woods and had the vision of a Crucifix floating suspended between the antlers of a stag—and is credited with formulating a set of rules and tactics to follow. Until very recent times, the saint was invoked as a cure for rabies (see also) through the use of a sacramental metal nail worked into the form of a cross called a St Hubert’s Key (Hubertusschlรผssel, Clef de Saint-Hubert), heated in fire and branded at the site of an animal bite, possibly with the effect of cauterising the wound.

lingua cosma (10. 215)

Though somewhat unclear whether mathematician Hans Freudenthal intended his constructed language to be practically applicable or just a thought-experiment and heuristic for thinking about how we might hurdle a potential language-barrier, his Lincos (a portmanteau of the above, see previously) was designed to be decipherable by any extraterrestrial life form—free of terrestrial syntax or context—and conducive to radio transmissions as part of the SETI program, it was meant to primarily convey propositional logic and universal constants. This narrow-band of communication—a bridge, however did not dissuade senior lecturer in Digital Media Studies at the University of Roehampton Richard Carter from anthologizing this alien-icebreaker in a collection of poems called Signals, which of course limn our limits of expression amongst ourselves as much as to other galactic denizens. Much more to explore at the links above.

time in a bottle (10. 087)

A favourite topic here at PfRC being the subject of time and time-keeping and having previously covered topics of Roman hours, the French Revolutionary Decimal Calendar, Time Zones, Knocker-Uppers and Daylight Savings Time, we quite enjoyed this latest instalment of You’re Dead to Me—the comedy podcast that takes history seriously, that explores both the want to escape the tyranny of clock and how in its measurement of time, our horizons are broadened beyond the immediate to the eminent. Following one tradition that informs the generally agreed upon standard, it was the Roman conquest of Greek Sicily and bringing back the sundial of Syracuse as a war trophy and putting it on public display (despite being calibrated for Sicily-time) was the beginning of regimented time-keeping with the fabulist Titus Maccius Plautus lamented of this new installation in the forum during the Punic Wars, duplicated all over the empire, “May the gods damn the man who first discovered the hours—when I was a boy, my stomach was the only sundial, but now what there is isn’t eaten lest the sun say so.” Much more to explore at the links above.
