“Common sense is calculation applied to life…”*

I updated my iPhone to the latest iOS version last week. Doing so required that “I agree” to Terms and Conditions amounting to 6,114 words: more than 37% longer than The Constitution of the United States (4,447). Although hardcore legalese enthusiasts may curl up with this masterpiece before the fire, mug of hot cocoa in hand, it will be read by virtually no one else. I clicked immediately, blissfully ignorant of my acquiescence…

Or maybe not so blissful. I was, in fact, vaguely annoyed at having just blindly accepted what amounts to a 24-page term paper (12-pt Times Roman, double-spaced). What, then, would fully informed consent cost?

$482,894,368, as it turns out.

With various reputable sources suggesting an average reading speed of 300 words per minute, 6,114 words would suck up 20.38 minutes of life for each user. Multiply by the average American’s hourly earnings of $24.09/hour (.4015/minute) and it’s $8.18257 in labor per updater.

A recently released study estimated Apple’s share of the 145 million-unit American  smartphone market at 40.7%. 59 million iPhoners.

59,015,00 x $8.18257 = $482,894,368

Perhaps more unsettling than money is the cumulative man-hours this particular endeavor would consume: 20-million.

59,015,000 x users x 20.38 minutes per= 1,202,725,700 minutes= 20 million hours…

As we carry the 1, we might recall that it was on this date in 1807 that Joseph Fourier’s monograph On the Propagation of Heat in Solid Bodies, was read to the Paris Institute.  An important mathematical work containing what we now call Fourier series, it was reviewed by renowned respondents including Lagrange, Laplace, Monge, and Lacroix– who objected to his innovation (the expansion of functions as trigonometrical series: the Fourier series).  Indeed, his work wasn’t published (in a revised and somewhat expanded form, as The Analytic Theory of Heat) until 1822.  Fourier’s contributions were ultimately judged so important that, in addition to the series, Fourier’s Law and Fourier’s transform were named in his honor.  And indeed, Fourier’s work, having first helped scientists and engineers understand heat transfer and vibrations, went on to help Watson and Crick discover the structure of DNA and to provide the underpinnings for quantum physics, radio astronomy, MP3 and JPEG compression, X-ray crystallography, voice recognition, and PET or MRI scans.

(Fourier was something of a polymath:  just before developing his mathematical advances, he went with Napoleon Bonaparte on his Egyptian expedition in 1798, and was made governor of Lower Egypt and secretary of the Institut d’Égypte, where he was involved in the discovery and decoding of the Rosetta Stone. And after the publication of The Analytic Theory of Heat, he discovered the Greenhouse Effect.)

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

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.”)

Explanations one would really rather not have to give…

EATR (source)

From a press release issued by Cyclone Power Technologies and Robotic Technology:

In response to rumors circulating the internet on sites such as FoxNews.com, FastCompany.com and CNET News about a “flesh eating” robot project [ c.f., e.g., EATR: The Robot That Can Survive on Corpses], Cyclone Power Technologies Inc. (Pink Sheets: CYPW) and Robotic Technology Inc. (RTI) would like to set the record straight: This robot is strictly vegetarian.

On July 7, Cyclone announced that it had completed the first stage of development for a beta biomass engine system used to power RTI’s Energetically Autonomous Tactical Robot (EATR™), a Phase II SBIR project sponsored by the Defense Advanced Research Projects Agency (DARPA), Defense Sciences Office. RTI’s EATR is an autonomous robotic platform able to perform long-range, long-endurance missions without the need for manual or conventional re-fueling.

RTI’s patent pending robotic system will be able to find, ingest and extract energy from biomass in the environment. Despite the far-reaching reports that this includes “human bodies,” the public can be assured that the engine Cyclone has developed to power the EATR runs on fuel no scarier than twigs, grass clippings and wood chips – small, plant-based items for which RTI’s robotic technology is designed to forage. Desecration of the dead is a war crime under Article 15 of the Geneva Conventions, and is certainly not something sanctioned by DARPA, Cyclone or RTI.

“We completely understand the public’s concern about futuristic robots feeding on the human population, but that is not our mission,” stated Harry Schoell, Cyclone’s CEO. “We are focused on demonstrating that our engines can create usable, green power from plentiful, renewable plant matter. The commercial applications alone for this earth-friendly energy solution are enormous.”

As we contemplate off-label uses, we might also celebrate the happier fall-out of military maneuvers, as it was on this date in 1799 (or close; scholars agree that it was “mid-July” but disagree on the precise day) that a French soldier in Napoleon’s Egyptian Campaign discovered a black basalt slab inscribed with ancient writing near the town of Rosetta, about 35 miles north of Alexandria.

The stone contained fragments of passages written in three different scripts inscribed by priests of Ptolemy V in the second century B.C.– Greek, Egyptian hieroglyphics, and Egyptian demotic.  The Greek passage proclaimed that the three scripts were all of identical meaning– so allowed French Egyptologist Jean Francois Champollion to decipher the hieroglyphics… and opened the language of ancient Egypt, a written language that had been “dead” for nearly two millennia.
