“Games are a compromise between intimacy and keeping intimacy away”*…
… Maybe, as Greg Costikyan explains, none more so than Rochambeau (or “Rock-Paper-Scissors” as it’s also known)…
Unless you have lived in a Skinner box from an early age, you know that the outcome of tic-tac-toe is utterly certain. At first glance, rock-paper-scissors appears almost as bad. A four-year-old might think there’s some strategy to it, but isn’t it basically random?
Indeed, people often turn to rock-paper-scissors as a way of making random, arbitrary decisions — choosing who’ll buy the first round of drinks, say. Yet there is no quantum-uncertainty collapse, no tumble of a die, no random number generator here; both players make a choice. Surely this is wholly nonrandom?
All right, nonrandom it is, but perhaps it’s arbitrary? There’s no predictable or even statistically calculable way of figuring out what an opponent will do next, so that one choice is as good as another, and outcomes will be distributed randomly over time — one-third in victory for one player, one-third to the opponent, one-third in a tie. Yes? Players quickly learn that this is a guessing game and that your goal is to build a mental model of your opponent, to try to predict his actions. Yet a naïve player, once having realized this, will often conclude that the game is still arbitrary; you get into a sort of infinite loop. If he thinks such-and-so, then I should do this-and-that; but, on the other hand, if he can predict that I will reason thusly, he will instead do the-other-thing, so my response should be something else; but if we go for a third loop — assuming he can reason through the two loops I just did — then . . . and so on, ad infinitum. So it is back to being a purely arbitrary game. No?
No…

As we play, we might send carefully-plotted birthday greetings to Vilfredo Pareto; he was born on this date in 1848. An engineer, mathematician, sociologist, economist, political scientist, and philosopher, he made significant contributions to math and sociology. But he is best remembered for his work in economics and socioeconomics– particularly in the study of income distribution, in the analysis of individuals’ choices, and in his studies of societies, in which he popularized the use of the term “elite” in social analysis.
He introduced the concept of Pareto efficiency (zero-sum situations in which no action or allocation is available that makes one individual better off without making another worse off) and helped develop the field of microeconomics. He was also the first to discover that income follows a Pareto distribution, which is a power law probability distribution. The Pareto principle ( the “80-20 rule”) was built on his observations that 80% of the wealth in Italy belonged to about 20% of the population.
“Infrastructure is much more important than architecture”*…
.. much, much more important, as Debbie Chachra explains in a piece featured once before in (R)D. It’s excerpted here again, with special emphasis on our power grid…
We use exogenous energy every day to exceed the limits of what our bodies can do. Artificial light compensates for our species’ poor night vision and gives us control over how we spend our time, releasing us from the constraints of sunrise and sunset. So valuable is artificial light that it’s a reliable correlate of wealth and economic development: researchers use the growing brightness of regions over time, as quantified from satellite images taken at night, as a proxy measure—more resources, more light. The southern half of the Korean Peninsula and the ocean surrounding it is ablaze with light; while North Korea has just faint threads of light leading out from Pyongyang, a result of decades of imposed scarcity.
Energy in the form of mechanical work also replaces our body’s labour, from the domestic scale—all the technologies for textiles, for example, from spinning and weaving to sewing and laundry—to scales that are nearly impossible for human bodies alone, like building skyscrapers and bridges. And we use mechanical energy to move our bodies and ferry goods around: transportation. Exogenous energy also makes our living environments more comfortable; for a long time, this was mostly limited to heating, but in the twentieth century, the technologies of refrigeration and air conditioning became widespread. The newest uses of energy are telecommunications technologies—from Morse code to TikTok, they turn electrons into bits of information, facilitating human connections on a global scale.
In fact, this ability to access more energy than our bodies themselves can provide is—all but literally—baked into being a human. All cultures eat cooked food (and no animals cook their food). While it’s not required to survive, strictly speaking, heating food breaks it down, making the nutrients more bioavailable; in essence, the food becomes more nutritious. Learning to cook our food is thought to have been an important contributor to the development of our calorie-dense brains and all that followed, helping to free humans from the ongoing labour of foraging and eating that occupies most animals. But the near-necessity of cooking food then requires a different labour: for most women on most of the planet, obtaining fuel for cooking remains their primary daily occupation.
“Care at Scale”
How is that we in the U.S. have more-or-less abundant power? Brian Potter explains the evolution of our electric grid…
Abundant electricity is a defining feature of the modern era. At the turn of the 20th century electrical power was a rare, expensive luxury: in 1900 electricity provided less than 5% of industrial power in the US, and as late as 1907 was in only 8% of US homes. Today, however, 89.6% of the world’s population has access to electricity (97.3% if you just consider urban areas), and Wikipedia’s “list of countries by electrification rate” has 123 countries sharing the top spot at 100% electrification.
Electrical service is considered critical in a way that’s different from most other services. Even a brief interruption in electrical power is considered a serious problem in industrialized countries where power outage durations are typically measured in minutes per year. To put this in perspective, the average yearly outage time in the US is around 475 minutes per year, which is considered especially unreliable despite representing ~99.9% uptime. By comparison, Germany averaged just 12.7 minutes of power outages per year in 2021—a remarkable 99.998% uptime.
Electricity’s transition from a luxury good to the foundation of modern life happened quickly. By 1930, electricity was available in nearly 70% of US homes, and supplied almost 80% of industrial mechanical power. By 1950, the US was tied together by an enormous network of high-voltage transmission lines…

As we think systemically, we might recall that it was on this date in 1752 that Benjamin Franklin and his son tested the relationship between electricity and lightning by flying a kite in a thunder storm. Franklin was attempting a (safer) variation on a set of French investigations about which he’d read. The French had connected lightning rods to a Leyden jar, but one of their experiments electrocuted the investigator. Franklin– who was, of course, no fool– used a kite; the increased height/distance from the strike reduces the risk of electrocution. (But it doesn’t eliminate it: Franklin’s experiment is now illegal in many states.)
In fact (other) French experiments had successfully demonstrated the electrical properties of lightning a month before, but word had not yet reached Philadelphia.

“I don’t believe in astrology; I’m a Sagittarius and we’re skeptical.”*…
(Roughly) Daily has looked at almanacs before (e.g., here and here), but never with an eye to their astrological underpinnings. Livia Gershon plugs that gap…
Some Christians today see astrology as a clear affront to their beliefs, and possibly a dangerous manifestation of the occult. And yet, as historian T.J. Tomlin writes, through the eighteenth century, it was a central aspect of the almanacs that were ubiquitous in Protestant American homes.
By 1800, Tomlin writes, U.S. printers produced enough almanacs to provide one to every household in the country. People turned to the books for a clear, simple idea of how the universe worked. Their astrological calculations helped readers gain practical know-how about agricultural management, weather, and personal health.
…
Like the study of the natural world in general in that time and place, almanacs were rooted in Protestantism. They presented simple, widely held religious ideas—God’s power, redemption through Christ, the promise of heaven—to an increasingly literate public. “This was the liturgy of early American popular culture,” Tomlin writes.
But there were debates about what sort of astrology was compatible with this religious belief. “Natural astrology,” using the movements of heavenly bodies to draw conclusions about agriculture, medicine, and the weather, was widely regarded as “a way to illuminate God’s creative impulse in the universe,” Tomlin writes. But “judicial astrology,” predicting the events of individual lives or political affairs, might be seen as blasphemous…

As we study the stars, we might send multi-faceted birthday greetings to the painter, sculptor, architect, musician, mathematician, engineer, inventor, physicist, chemist, anatomist, botanist, geologist, cartographer, and writer– the archetypical Renaissance Man– Leonardo da Vinci. Quite possibly the greatest genius of the last Millennium, he was born on this date in 1452.
While Leonardo’s attention (and thus his notebooks) extended to astronomy, there’s no evidence that he believed in astrology. That said, his chart has been cast myriad times (e.g., here).

Thomas Midgley, Jr. (1889–1944) was an American engineer and chemist who contracted polio at age 51, leaving him severely disabled. He devised an elaborate system of ropes and pulleys to help others lift him from bed. He became accidentally entangled in the ropes and died of strangulation at the age of 55. However, he is better known for two of his other inventions: the tetraethyl lead (TEL) additive to gasoline, and chlorofluorocarbons (CFCs) [as we’ve noted in (Roughly) Daily before]…

As we practice prudence, we might spare a thought for F. Sherwood Rowland; he died on this date in 2012. A chemist who focused on atmospheric chemistry, he is best remembered as the man who “outed” Thomas Midgley– that’s to say, for his discovery that chlorofluorocarbons contribute to ozone depletion– for which he shared 1995 Nobel Prize for Chemistry.
“A chicken in every pot”*…
How and when were chickens domesticated, and turned into a staple source of protein? As Ann Gibbons reports, new studies propose a surprisingly late date, and a link to rice cultivation…
From chicken biryani to khao mun gai, chicken and rice is a winning combo worldwide. But the two are more inextricably linked than even chefs realized. A pair of new archaeological studies suggest that without rice, chickens may have never existed.
The work reveals that chickens may have been domesticated thousands of years later than scientists thought, and only after humans began cultivating rice within range of the wild red jungle fowl, in Thailand or nearby in peninsular Southeast Asia, says Dale Serjeantson, an archaeologist at the University of Southampton who was not involved with the research. The studies, she says, have “dismantled many of the hoary myths about chicken origins.”…

As we ponder poultry, we might spare a thought for Lillian Evelyn Moller Gilbreth; she died on this date in 1972. One of the first working female engineers holding a Ph.D., she was arguably the first true industrial/organizational psychologist. With her husband Frank Gilbreth, she was one of the first “efficiency experts” helping establish the fields of motion study and human factors. She is perhaps best remembered as the subject of Cheaper by the Dozen and Belles on Their Toes (charming books written by their children Ernestine and Frank Jr.) recounting the couple’s family life with their twelve children, and their application of time and motion study to the organization and daily routines of such a large family.
As we’ve seen before, she was instrumental in the development of the modern kitchen, creating the “work triangle” and linear-kitchen layouts that are often used today– enabling the preparation of lots of chicken.
