Seen above is a green disc, wax on brass, with an early recording of  Hamlet’s “To be or not to be…” soliloquy, that likely hasn’t been heard  in over 125 years. Created by Alexander Graham Bell’s Volta Laboratory in the late 19th Century and sent to the Smithsonian for archiving as they were created, the paranoid Bell failed to provide a playback mechanism for these discs, for fear that his competitors would appropriate his innovations.
Researchers at the Lawrence Berkeley National Laboratories are working on recovering these early audio recordings with a system called IRENE/3D that creates 3D optical scans of the old record-like discs:

Using methods derived from our work on instrumentation for particle physics we have investigated the problem of audio reconstruction from mechanical recordings.  The idea was to acquire digital maps of the surface of the media, without contact, and then apply image analysis methods to recover the audio data and reduce noise.

The nifty thing about this form of hands-off scanning is that it can accommodate many types of otherwise mechanically incompatible media, from discs made of metal or glass to wax cylinders (quick, someone set this up to scan the Lazarus bowl!!). The 18-second snippet of Hamlet audio from the green disc above (maybe the voice of Bell himself?) has been posted on YouTube, or you can download more examples from the project in WAV and MP3 format.

"This tattooing had been the work of a departed prophet and seer of his island, who, by those hieroglyphic marks, had written out on his body a complete theory of the heavens and the earth, and a mystical treatise on the art of attaining truth; so that Queequeg in his own proper person was a riddle to unfold; a wondrous work in one volume; but whose mysteries not even himself could read, though his own live heart beat against them; and these mysteries were therefore destined in the end to moulder away with the living parchment whereon they were inscribed, and so be unsolved to the last."

The description of Queequeg’s tattoos quoted on the blog The Loom, the author of which has a new book out about science-inspired tattoos. It hadn’t occurred to me when reading Moby-Dick, but European sailors had only been decorating themselves with tattoos for some 80 years by the time the book came out — the first example of the word used in English was recorded in Captain Cook’s naturalist’s journals in 1769. 

(Here’s the original passage from Moby-Dick)

bobulate:

Want to remember an experience? Don’t move.

That’s overstating it, but a new study shows that just walking through a doorway creates what’s called a “new memory episode,” which makes it difficult to remember the experience in the previous room:

[M]emory performance was poorer after travelling through an open doorway, compared with covering the same distance within the same room. “Walking through doorways serves as an event boundary, thereby initiating the updating of one’s event model [i.e. the creation of a new episode in memory]” the researchers said.

Apparently, there can be these sort of episode markers — “a while later” — in stories as well.

Curious what episode markers mark our digital spaces.

Perhaps correlations could be drawn here to the subject of memory palaces or even psychological / mythological concepts of thresholds and liminality. It’s very interesting that real, literal movement through spaces can impact our relationship with memory.

On gunpowder, ice cream, and sound symbolism

From the post Language of Food: Ice Cream, a fascinating article linking the history of gunpowder, ice cream, linguistics, and even a bit of marketing insight:

Something similarly beautiful was created as saltpeter and snow, sherbet and salt, were passed along and extended from the Chinese to the Arabs to the Mughals to the Neapolitans, to create the sweet lusciousness of ice cream. And it’s a nice thought that saltpeter, applied originally to war, became the key hundreds of years later to inventing something that makes us all smile on a hot summer day.

If you like food, language, or science, the full post is worth a read.

From a post titled The Art of Nomography on Dead Reckonings (a blog dedicated to forgotten-but-beautiful mathematical systems! I’d better subscribe to this one…) :

Nomography, truly a forgotten art, is the graphical representation of  mathematical relationships or laws (the Greek word for law is nomos). These graphs are variously called nomograms (the term used here), nomographs, alignment charts, and abacs.  This area of practical and theoretical mathematics was invented in 1880  by Philbert Maurice d’Ocagne (1862-1938) and used extensively for many  years to provide engineers with fast graphical calculations of  complicated formulas to a practical precision.
Along with the mathematics involved, a great deal of ingenuity went  into the design of these nomograms to increase their utility as well as  their precision. Many books were written on nomography and then driven  out of print with the spread of computers and calculators, and it can be  difficult to find these books today even in libraries. Every once in a  while a nomogram appears in a modern setting, and it seems odd and  strangely old-fashioned—the multi-faceted Smith Chart for transmission  line calculations is still sometimes observed in the wild. The theory of  nomograms “draws on every aspect of analytic, descriptive, and  projective geometries, the several fields of algebra, and other  mathematical fields” [Douglass].

I’ve heard that plants attract insects and other pollinators using nectar guides (nature’s own user interface!), but I’ve never heard of this adaptation: the plants depicted above manipulate sound rather than light to attract attention, a bit of floral acoustics.

Ralph Simon at the University of Ulm in Germany and his colleagues  analysed the leaf’s acoustic properties and found that its unique shape  produces a strong, constant echo across a range of sound-source angles.  They then trained bats to seek a feeder hidden in artificial foliage.  The animals found feeders topped with the cup shape in an average of 12  seconds — around half the time it took them to locate unadorned feeders  or those under other leaf shapes.

NASA has teamed up with LEGO to blast the above three custom minifigs to Jupiter via an Atlas V rocket! There’s so much about this idea that excites the little kid in me. The three aluminum individuals going along for the ride are the goddess Juno (namesake of this NASA Jupiter probe project), bearing an outsized magnifying glass; Jupiter himself, with lightning bolts; and Galileo, with telescope and globe, who isn’t a god but made followers of one kind of angry back in the day when he started noticing and thinking about the moons circling the distant planet.
If these weren’t cast in metal, I’d like to think all three would be wearing the classic LEGO Space logo suit.

Herman Melville on the Nature of Color

From Moby Dick, chapter 42, “The Whiteness of the Whale”:

Is it that by its indefiniteness it shadows forth the heartless voids and immensities of the universe, and thus stabs us from behind with the thought of annihilation, when beholding the white depths of the milky way? Or is it, that as in essence whiteness is not so much a color as the visible absence of color, and at the same time the concrete of all colors; is it for these reasons that there is such a dumb blankness, full of meaning, in a wide landscape of snows - a colorless, all-color of atheism from which we shrink? And when we consider that other theory of the natural philosophers, that all other earthly hues - every stately or lovely emblazoning - the sweet tinges of sunset skies and woods; yea, and the gilded velvets of butterflies, and the butterfly cheeks of young girls; all these are but subtile deceits, not actually inherent in substances, but only laid on from without; so that all deified Nature absolutely paints like the harlot, whose allurements cover nothing but the charnel-house within; and when we proceed further, and consider that the mystical cosmetic which produces every one of her hues, the great principle of light, for ever remains white or colorless in itself, and if operating without medium upon matter, would touch all objects, even tulips and roses, with its own blank tinge - pondering all this, the palsied universe lies before us a leper; and like wilful travellers in Lapland, who refuse to wear colored and coloring glasses upon their eyes, so the wretched infidel gazes himself blind at the monumental white shroud that wraps all the prospect around him. And of all these things the Albino Whale was the symbol. Wonder ye then at the fiery hunt?

Cryptochrome

Research continues on whether humans (and other animals) have the ability to perceive magnetic fields:

Many birds have a compass in their eyes. Their retinas are loaded with a protein called cryptochrome, which is sensitive to the Earth’s magnetic fields. It’s possible that the birds can literally see these fields, overlaid on top of their normal vision. This remarkable sense allows them to keep their bearings when no other landmarks are visible.

But cryptochrome isn’t unique to birds – it’s an ancient protein with versions in all branches of life. In most cases, these proteins control daily rhythms. Humans, for example, have two cryptochromes – CRY1 and CRY2 – which help to control our body clocks. But Lauren Foley from the University of Massachusetts Medical School has found that CRY2 can double as a magnetic sensor.

Vision is amazing, even more so when you take into account the myriad other things that animals and insects can detect beyond just our “visible” EMF spectrum. See also: box jellyfish with their surprisingly complex (and human-like) set of 24 eyes.

Researchers at the Karlsruhe Institute of Technology set a new record by transmitting 26 terabits of a data per second (“the entire Library of Congress in 10 seconds!” as the usual benchmark goes) using a single laser and a clever FFT and frequency comb technique to split the light into 300+ discrete colors:

The Fourier transform is a well-known mathematical trick that can in essence extract the different colours from an input beam, based solely on the times that the different parts of the beam arrive. The team does this optically - rather than mathematically, which at these data rates would be impossible - by splitting the incoming beam into different paths that arrive at different times, recombining them on a detector. In this way, stringing together all the data in the different colours turns into the simpler problem of organising data that essentially arrive at different times.

Neat.

From Discover:

This futuristic method is based on a centuries-old observation that electric fields can do funny things (videos) to flames, making them sputter and even snuffing them out.

The researchers’ early-stage prototype consists of a 600-watt amplifier hooked up to a electric beam-shooting wand, according to their presentation at the American Chemical Society meeting earlier this week.  In tests, they were able to quickly zap out flames over a foot high.

I look forward to the day when I can dial 911 and get the ArcAttack guys over to put out the blaze!

Actually, he does. Donald Duck accidentally (and somewhat accurately) described the chemical compound methylene nearly two decades before real-world scientists:

In 1963, the Disney Studio learned just how wide and faithful a  readership [Carl] Barks had. A letter arrived from Joseph B. Lambert of the  California Institute of Technology, pointing out a curious reference in  “The Spin States of Carbenes,” a technical article soon to be published  by P.P. Gaspar and G.S. Hammond (in Carbene Chemistry, edited by  Wolfgang Kirmse, New York:  Academic Press, 1964). “Despite the recent extensive interest in  methylene chemistry,” read the article’s last paragraph, “much  additional study is required…. Among experiments which have not, to our  knowledge, been carried out as yet is one of a most intriguing nature  suggested in the literature of no less than 19 years ago (91).” Footnote  91, in turn, directed readers to issue 44 of Walt Disney’s Comics and  Stories. … A  year later, the Studio received a letter from Richard Greenwald, a  scientist at Harvard. “Recent developments in chemistry have focused  much attention to species of this sort,” Greenwald commented. “Without  getting technical let me say that carbenes can be made but not isolated;  i.e. they cannot be put into a jar and kept on a shell. They can,  however, be made to react with other substances. Donald was using  carbene in just such a manner, many years before ‘real chemists’ thought  to do so.”

Mind-boggling stuff like this is why I keep reading science journals. We can already use photons to push and pinch things with their tiny mass (amazing enough), but new research is underway in how to pull with photons:

Light is pushy. The physical pressure of photons is what allows for solar sail space missions that ride on sunlight, and what allows for dreams of lasers that will push those sails even faster. And light can trap objects, too: Optical tweezers can hold tiny objects in place. Pulling an object with light, however, is another matter.  …  Jun Chen’s research team says that the key is to use not a regular laser beam, but instead what’s called a Bessel beam. Viewed head-on, a Bessel beam looks like one intense point surrounded by concentric circles—what you might see when you toss a stone into a lake.

From the Journal of Experimental Biology comes news that caterpillars are able to force air through their bodies to ‘whistle’ as a defense mechanism when they’re spotted by predators. These aren’t exotic bugs, either: they can be found all over the U.S., even here in Austin, Texas (guess I’d better listen carefully next time I’m in the backyard). From the Nature abstract:

When under attack, walnut sphinx caterpillars (Amorpha juglandis), whistle. An 1868 Canadian Entomologist paper, “Musical larvae,” first reported these shrieks, but their purpose wasn’t clear.

Jayne Yack at Carleton University in Ottawa, Canada, and her team now show that the whistle, produced through openings along the body called spiracles, is a defence against predators. Simulated attacks with blunt tweezers caused the caterpillars to pull their heads back, forcing air through two of the spiracles in a succession of squeaks.

There’s a video of the little guy whistling available in .mov format. I think I’d squeak too if someone was jabbing at me with a pair of forceps…
