“Nothing is built on stone; all is built on sand”*…

(Roughly) Daily has looked before at sand: as a scarce resource, thus as a valuable commodity and an object of theft, and as a metaphor. In this excerpt from his book, The World in a Grain: The Story of Sand and How It Transformed Civilization, Vince Beiser makes the case that it is the most important solid substance on earth…
[Sand is] the literal foundation of modern civilization. … Sand is the main material that modern cities are made of. It is to cities what flour is to bread, what cells are to our bodies: the invisible but fundamental ingredient that makes up the bulk of the built environment in which most of us live.
Sand is at the core of our daily lives. Look around you right now. Is there a floor beneath you, walls around, a roof overhead? Chances are excellent they are made at least partly out of concrete. And what is concrete? It’s essentially just sand and gravel glued together with cement.
Take a glance out the window. All those other buildings you see are also made from sand. So is the glass in that window. So are the miles of asphalt roads that connect all those buildings. So are the silicon chips that are the brains of your laptop and smartphone. If you’re in downtown San Francisco, in lakefront Chicago, or at Hong Kong’s international airport, the very ground beneath you is likely artificial, manufactured with sand dredged up from underwater. We humans bind together countless trillions of grains of sand to build towering structures, and we break apart the molecules of individual grains to make tiny computer chips.
Some of America’s greatest fortunes were built on sand. Henry J. Kaiser, one of the wealthiest and most powerful industrialists of twentieth-century America, got his start selling sand and gravel to road builders in the Pacific Northwest. Henry Crown, a billionaire who once owned the Empire State Building, began his own empire with sand dredged from Lake Michigan that he sold to developers building Chicago’s skyscrapers. Today the construction industry worldwide consumes some $130 billion worth of sand each year.
Sand lies deep in our cultural consciousness. It suffuses our language. We draw lines in it, build castles in it, hide our heads in it. In medieval Europe (and a classic Metallica song), the Sandman helped ease us into sleep. In our modern mythologies, the Sandman is a DC superhero and a Marvel supervillain. In the creation myths of indigenous cultures from West Africa to North America, sand is portrayed as the element that gives birth to the land. Buddhist monks and Navajo artisans have painted with it for centuries. ‘Like sands through the hourglass, so are the days of our lives,’ intone the opening credits of a classic American soap opera. William Blake encouraged us to ‘see a world in a grain of sand.’ Percy Bysshe Shelley reminded us that even the mightiest of kings end up dead and forgotten, while around them only ‘the lone and level sands stretch far away.’ Sand is both minuscule and infinite, a means of measurement and a substance beyond measuring.
Sand has been important to us for centuries, even millennia. People have used it for construction since at least the time of the ancient Egyptians. In the fifteenth century, an Italian artisan figured out how to turn sand into fully transparent glass, which made possible the microscopes, telescopes, and other technologies that helped drive the Renaissance’s scientific revolution.
But it was only with the advent of the modern industrialized world, in the decades just before and after the turn of the twentieth century, that people really began to harness the full potential of sand and begin making use of it on a colossal scale. It was during this period that sand went from being a resource used for widespread but artisanal purposes to becoming the essential building block of civilization, the key material used to create mass-manufactured structures and products demanded by a fast-growing population.
At the dawn of the twentieth century, almost all of the world’s large structures — apartment blocks, office buildings, churches, palaces, fortresses — were made with stone, brick, clay, or wood. The tallest buildings on Earth stood fewer than ten stories high. Roads were mostly paved with broken stone, or more likely, not paved at all. Glass in the form of windows or tableware was a relatively rare and expensive luxury. The mass manufacture and deployment of concrete and glass changed all that, reshaping how and where people lived in the industrialized world.
Then in the years leading up to the twenty-first century, the use of sand expanded tremendously again, to fill needs both old and unprecedented. Concrete and glass began rapidly expanding their dominion from wealthy Western nations to the entire world. At roughly the same time, digital technology, powered by silicon chips and other sophisticated hardware made with sand, began reshaping the global economy in ways gargantuan and quotidian.
Today, your life depends on sand. You may not realize it, but sand is there, making the way you live possible, in almost every minute of your day. We live in it, travel on it, communicate with it, surround ourselves with it…

As we muse on minerals, we might note that it was on this date in 1913 that a famous “sand castle” (concrete building) was opened in New York City, the neo-Gothic Woolworth Building. Located at 233 Broadway in the Tribeca neighborhood of Manhattan, it was the tallest building in the world from 1913 to 1930, at a height of 792 feet; more than a century after its construction, it remains one of the 100 tallest buildings in the United States.
The Woolworth Building has been a National Historic Landmark since 1966 and a New York City designated landmark since 1983. The building is assigned its own ZIP Code, 10279, one of 41 buildings in Manhattan so “honored” as of 2019.

“By the 1980’s and 1990’s, Moore’s Law had emerged as the underlying assumption that governed almost everything in the Valley, from technology to business, education, and even culture”*…

“Quantum dots”
… and Moore’s Law— the assertion that the number of transistors in a dense integrated circuit doubles approximately every two years– has indeed weathered pretty well since Gordon Moore coined it in 1965:

Still, all along the way there have been nay-sayers– those who believe that it simply must come to an end. Even Intel, which Moore co-founded after serving as Director of Research at Fairchild, the semiconductor pioneer at which he worked when he published his “law,” has now questioned whether “doubling every two years” can continue.
Of course, only time will tell. But believers can take heart in work recently published by Cornell researchers on their work with “quantum dots” [pictured at the top of this post].
Just as the single-crystal silicon wafer forever changed the nature of communication 60 years ago, Cornell researchers hope their work with quantum dot solids — crystals made out of crystals — can help usher in a new era in electronics.
The team has fashioned two-dimensional superstructures out of single-crystal building blocks. Using a pair of chemical processes, the lead-selenium nanocrystals are synthesized into larger crystals, then fused together to form atomically coherent square superlattices.
The difference between these and previous crystalline structures is the atomic coherence of each 5-nanometer crystal (a nanometer is one-billionth of a meter). They’re not connected by a substance between each crystal — they’re connected to each other directly. The electrical properties of these superstructures are potentially superior to existing semiconductor nanocrystals, with anticipated applications in energy absorption and light emission…

The “law” said the number of transistors would double every couple of years. It dictated that nothing stays the same for more than a moment; no technology is safe from its successor; costs fall and computing power increases not at a constant rate but exponentially: If you’re not running on what became known as ” Internet time,” you’re falling behind.”

As we get small, we might send thoughtful greetings to a man who can no doubt come up with new uses for that power– Seymour Papert; he celebrates his birthday on this date (as he was born on February 29, Leap Day, in 1928). Trained as a mathematician, Papert has been a pioneer of computer science, and in particular, artificial intelligence. He created the Epistemology and Learning Research Group at the MIT Architecture Machine Group (which later became the MIT Media Lab); he directed MIT’s Artificial Intelligence Laboratory; he authored the hugely-influential LOGO computer language; and he is a principal of the One Laptop Per Child Program. Called by Marvin Minsky “the greatest living mathematics educator,” Papert has won won a Guggenheim fellowship (1980), a Marconi International fellowship (1981), the Software Publishers Association Lifetime Achievement Award (1994), and the Smithsonian Award (1997).
“A day will come when there will be no battlefields, but markets opening to commerce and minds opening to ideas”*…
… well, markets opening anyway.
There’s a rule of thumb that to have a healthy diet, you should eat the rainbow—meaning fruits and veggies of all colors. A similar notion could be applied to a country’s economic health. The more diverse the exports, the less susceptible a nation will presumably be to fluctuations in a single market. Too reliant on oil? A drop in prices might spell the loss of billions of dollars. And for a country where heavy machinery comprises most of the exports, that drop in prices might mean lower operating costs and an uptick in sales. And thanks to globalization, the web of trade is very complex and tough to comprehend.
Looking for better ways to unpack this data, Harvard researchers mapped out international exports in an infographic called the Globe of Economic Complexity, an interactive website that visualizes the exports of every country around the world.
Industries like agriculture, medical products, precious metals, cars, and even baked goods are all assigned a specific color. To get more detailed breakdowns, the infographic leads you to an atlas of exports with more detailed breakdowns. The data was collected in 2012 and for that year, the graphic shows the United States as predominantly turquoise (machinery and parts), blue (automotive), and fuchsia (chemicals). Spin the globe and head over to China and nearly half of the exports are machinery related. Saudi Arabia is a beacon of pink for petroleum, accounting for 76% of exports. Clicking on the country names shows who the nation exports to the most.
Changing to different views, like the product space graph, reveals which countries are most heavily involved in the trade of a specific product. Who knew that the United Kingdom accounted for 26% of the antiques trade or that Europe exports the most cigarette papers?

As we note sadly that two countries with McDonald’s franchises have in fact gone to war, we might send charged birthday greetings to Ernest Rutherford, 1st Baron Rutherford of Nelson; he was born on this date in 1871. An experimental physicist whose work earned him the honorifics “father of nuclear physics” and “father of electronics” (along with a Nobel Prize), he is considered the greatest experimentalist since Michael Faraday, and and was instrumental in laying the foundation for the advances in technology and energy that have enabled the globalization visualized above.
From The Annals of Audacity: (Not) Guilty As Charged…
Mirco Pagano and Moreno De Turco have created the likenesses of seven musicians– Jimi Hendrix (above), Jim Morrison, Michael Jackson, Bob Marley, James Brown, Freddie Mercury and Elvis, each caught on the floor as though the victim of a shooting– by carefully “spilling” their CDs. It’s an arresting feat.
But their work is part of Piracy, an ad campaign, film short and sculptural work by ad agency TBWA. The conceit is that these musicians were ultimately brought down by internet piracy– ridiculous, as most of these artists died before “piracy” even had a name, and all profited handsomely from their recorded work. To the extent that “piracy” is even an issue, in these cases the “endangered” aren’t the artists, but the record companies trying to milk their cash cows into eternity. As Visual News (to whom, TotH) observes, “what looks like passion becomes something far more sinister.”

As we sigh, we might send electrifying birthday greetings to the man who made all of this “piracy” possible– not just in its current on-line form, but in its earlier (and also recording industry-feared) broadcast incarnations– Lee De Forest; he was born on this date in 1873. While he ultimately held 300 patents on a variety of inventions that abetted electronic communications, and co-founded the forerunner organization to the IEEE, De Forest is probably best remembered as the inventor of the Audion vacuum tube, which made possible live radio broadcasting and became the key component of all radio, telephone, radar, television, and computer systems before the invention of the transistor in 1947.
Unwittingly then had I discovered an Invisible Empire of the Air, intangible, yet solid as granite, whose structure shall persist while man inhabits the planet.
– Father of Radio: The Autobiography of Lee De Forest (1950), p. 4
