Antipodr is a nifty little site that lets visitors learn what's on the opposite side of the globe from any coordinate. For instance, Auckland, New Zealand is directly opposite Venta de Leche in southern Spain. Read the rest

In much of the world, addresses are difficult to convey because they refer to locations on unnamed streets, in unnumbered buildings, in unincorporated townships, sometimes in disputed national boundaries (I have often corresponded with people in rural Costa Rica whose addresses were "So-and-so, Road Without Name, 300m west of the bus stop, village, nearest town, region").

Londonist's roundup of cutaway maps -- many from the outstanding Transport Museum in Covent Garden -- combines the nerdy excitement of hidden tunnels with the aesthetic pleasure of isomorophic cutaway art, along with some interesting commentary on both the development of subterranean tunnels and works and the history of representing the built environment underground in two-dimension artwork.

In 1971, astronomer Frank Drake, the father of the search for extraterrestrial intelligence, drew a map pinpointing Earth in our galaxy. That diagram, a "pulsar map," was etched on a plaque designed by Frank and Carl Sagan and first carried into space in 1972 by the Pioneer 10 and 11 spacecraft. In 1977, the pulsar map would appear again etched on the covers of the golden records affixed to the the Voyager probes. These days, Frank's original pencil drawing of the map is stored in an old tomato box at his house. (In fact, Frank kindly allowed us to scan it for our book included in our new Voyager Golden Record vinyl box set!) Over at National Geographic, Nadia Drake, one of my favorite science journalists who also happens to be Frank's daughter, tells the fascinating story of this iconic piece of cosmic cartography. From National Geographic:

The question was, how do you create such a map in units that an extraterrestrial might understand?

...To my dad, the answer was obvious: pulsars. Discovered in 1967 by Jocelyn Bell Burnell, these dense husks of expired stars were perfect blazes in both space and time.

For starters, pulsars are incredibly long-lived, staying active for tens of millions to multiple billions of years.

Also, each pulsar is unique. They spin almost unbelievably fast, and they emit pulses of electromagnetic radiation like lighthouses. By timing those pulses, astronomers can determine a pulsar’s spin rate to a ridiculous degree of accuracy, and no two are alike.

In the late 19th century, travel times became a thing of fascination as modes of transportation improved by leaps and bounds (e.g., Around the World in 80 Days, published in 1873). Great thinkers of the day like Francis Galton even devised isochrone maps, which showed how long it would take to get from a central point to other points of interest. Read the rest

The Mercator projection maps we're all familiar with dates to a 16th-centry Flemish cartographer who wanted to emphasize colonial trade routes; as a result, it vastly distorts the relative sizes and positions of the world's continents, swelling Europe and North America to absurd proportions and shrinking South America and Africa.

Sebastian C. Adams's Synchronological Chart from the late 19th century presents 5,885 years of history (4004 BCE - 1881 AD) on a magnificent 27 inch x 23 foot illustrated and annotated timeline. What a stunner. You can zoom and pan through the whole thing at the David Rumsey Map Collection or order a scaled-down print.

According to the book Cartographies of Time: History of the Timeline, the Synchronological Chart "was ninetheenth-century America's surpassing achievement in complexity and synthetic power."

What happens when a professional cartographer needs a break? For Sasha Trubetskoy, it meant making a map of the Bay Area based on Urban Dictionary entries. Berzerkely, Freakmont, Pathetica, and The Yoch are just a few points of interest. Read the rest

Several years ago, a new apartment building went up at 1600 Pennsylvania Avenue SE in Washington DC. That's a few miles from the better known 1600 Pennsylvania Avenue, aka the White House. A car lot was previously on the apartment building property, then registered as 1550 Pennsylvania Avenue SE, but the developers thought it would be a hoot to petition for the 1600 Pennsylvania Avenue SE address. They got it. From WTPO:

Residents say they often get funny looks or disbelief when they have to give their address or hand over their driver’s licenses. Carlos Gutierrez, 39, and other residents said they get asked: “You live at the White House?”

The address has produced headaches for some residents. One early resident of the building, Daniel Perry, 36, said Amazon.com initially wouldn’t take orders to the address, though that’s since been sorted out. Another resident said even now, she sometimes has difficulty ordering online. A recent order for a pair of summer sandals required calling the company, she said.

Residents have to make sure that anyone sending them mail puts the all-important “SE” after the address. The correct zip code — 20003 — is also key. The White House’s ZIP code is 20500.

A goof means the mail might eventually get to the correct recipient, but because the president’s mail gets extra security screening, any resident’s mail with an incomplete address could be significantly delayed.

Mail mix-ups happen the other way, too. Errant letters for the first family arrive at the building every so often and sit unopened by the residents’ mailboxes until the U.S.
