“Few things are more enjoyable than lingering over the atlas and plotting a trip”*…

I’m excited to finally share a new design project this week! Over the past year and a half I’ve been working on a collection of ten maps on planets, moons, and outer space. To name a few, I’ve made an animated map of the seasons on Earth, a map of Mars geology, and a map of everything in the solar system bigger than 10km…
Data visualizer extraordinaire Eleanor Lutz has announced “An Atlas of Space.”

As we see stars, we might spare a thought for Daniel Kirkwood; he died on this date in 1895. Kirkwood’s most significant contribution came from his study of asteroid orbits. When arranging the then-growing number of discovered asteroids by their distance from the Sun, he noted several gaps, now named Kirkwood gaps in his honor, and associated these gaps with orbital resonances with the orbit of Jupiter. Further, Kirkwood also suggested a similar dynamic was responsible for Cassini Division in Saturn’s rings, as the result of a resonance with one of Saturn’s moons. In the same paper, he was the first to correctly posit that the material in meteor showers is cometary debris.
Kirkwood also identified a pattern relating the distances of the planets to their rotation periods, which was called Kirkwood’s Law. This discovery earned Kirkwood an international reputation among astronomers; he was dubbed “the American Kepler” by Sears Cook Walker, who claimed that Kirkwood’s Law proved the widely held Solar Nebula Theory. (In the event, the “Law” has since become discredited as new measurements of planetary rotation periods have shown that the pattern doesn’t hold.)

Harmonia Macrocosmica (1660), an atlas of the stars from the Dutch Golden Age of cartography, maps the structure of the heavens in twenty-nine extraordinary double-folio spreads. We are presented with the motions of the celestial bodies, the stellar constellations of the northern hemisphere, the old geocentric universe of Ptolemy, the newish heliocentric one of Copernicus [as above], and Tycho Brahe’s eccentric combination of the two — in which the Moon orbits the Earth, and the planets orbit the Sun, but the Sun still orbits the Earth. The marginal area of each brightly coloured map is a hive of activity: astronomers bent over charts debate their findings, eager youngsters direct their quadrants skywards, and cherubs fly about with pet birds in tow…

As we look to the stars, we might recall that it was on this date in 1843 that Sir William Rowan Hamilton conceived the theory of quaternions. A physicist, astronomer, and mathematician who made important contributions to classical mechanics, optics, and algebra, he had been working since the late 1830s on the basic principles of algebra, resulting in a theory of conjugate functions, or algebraic couples, in which complex numbers are expressed as ordered pairs of real numbers. But he hadn’t succeeded in developing a theory of triplets that could be applied to three-dimensional geometric problems. Walking with his wife along the Royal Canal in Dublin, Hamilton realized that the theory should involve quadruplets, not triplets– at which point he stopped to carve carve the underlying equations in a nearby bridge lest he forget them.

For much of the 17th century, Europeans believed that California was an island. Indeed, readers who have suffered through your correspondent’s explanation of scenario planning know that a 17th century map in which California is depicted as an island, very like the one above, figures into the talk as an example of the way that incorrect maps– cartographical or mental maps– are hard to change and often lead us astray.
But as this appreciation of Stanford’s collection of California maps points out, there may be a deeper truth to the depiction:
The fact that a number of explorers knew that California was not an island was not enough to nip the idea in the bud. Yet it would be a shame to think of the idea as simply an error, a cartographical crease which needed ironing out. Even though maps may be presented as accurate, they cannot escape their metaphorical nature. They reflect much more than physical geography. That California was mapped as an island for so long speaks to its separateness. The writer Rebecca Solnit, a student of the Stanford maps, has argued that, “An island is anything surrounded by difference.” The state contains around 2,000 plant species found nowhere else. Its borders comprise dizzying mountains, harsh deserts and immense ocean. It has been home to the Gold Rush, the psychedelic era, the silicon boom. In several ways then, California is an island…

As we remember that “the map is not the territory,” we might recall that it was on this date in 1570 that Gilles Coppens de Diest at Antwerp published Flemish cartographer Abraham Ortelius’ Theatrum Orbis Terrarum— a collection of 53 maps that is generally agreed to have been the first modern atlas.
Interestingly (for reasons explained in the article linked above), Ortelius’ maps, which pre-date the charts in the Stanford collection, portray California more accurately.

“A map does not just chart, it unlocks and formulates meaning; it forms bridges between here and there, between disparate ideas that we did not know were previously connected”*…

And as a (more global) bonus: Edward Quin’s 1830 Historical Atlas in a Series of Maps of the World as Known at Different Periods, with an Historical Narrative, featuring 21 plates that visually depicted what Quin called “the world as known at different periods.” Dramatic clouds cover the “unknown,” rolling back slowly as time moves on.

As we travel through time, we might recall that it was on this date in 1861 that New York City Mayor Fernando Wood, a “Copperhead” (sympathizer of the incipient Confederate cause), suggested to the New York City Council that New York secede and declare itself a free city, to continue its profitable cotton trade with the Confederacy. Wood’s Democratic machine was concerned to maintain the revenues (which depended on Southern cotton) that maintained the patronage that provided its electoral margins.
