Google Maps for the Roman World

111

"ORBIS — the Stanford Geospatial Network Model of the Roman World."

From the website:

Spanning one-ninth of the earth's circumference across three continents, the Roman Empire ruled a quarter of humanity through complex networks of political power, military domination, and economic exchange. These extensive connections were sustained by premodern transportation and communication technologies that relied on energy generated by human and animal bodies, winds, and currents.

Conventional maps that represent this world as it appears from space signally fail to capture the severe environmental constraints that governed the flows of people, goods and information. Cost, rather than distance, is the principal determinant of connectivity.

For the first time, ORBIS allows us to express Roman communication costs in terms of both time and expense. By simulating movement along the principal routes of the Roman road network, the main navigable rivers, and hundreds of sea routes in the Mediterranean, Black Sea, and coastal Atlantic, this interactive model reconstructs the duration and financial cost of travel in antiquity.

Taking account of seasonal variation and accommodating a wide range of modes and means of transport, ORBIS reveals the true shape of the Roman world and provides a unique resource for our understanding of premodern history.

Fair warning: there goes the summer.

One definition of faith

McCandless

Above, astronaut Bruce McCandless II floats completely untethered, away from the safety of the space shuttle, with nothing but his Manned Maneuvering Unit keeping him alive.

He was — and always will be — the first person in history to do so, on February 7, 1984.

Back story from NASA here.

You know what song I'm hearing....

Egg Levitation

From Savvas Papasavva:

In this video I attempt to recreate an excerpted account of how to levitate an egg from "The Ten Thousand Infallible Arts of the Prince of Huainan."

Despite managing to reduce the weight of an egg by several grams, and even after extracting the membrane beneath the shell, all my attempts to levitate the egg failed, instead simply setting it on fire and making a stink.

I concluded that I was not trying hard enough and that if a psychotic monarch had expected me to make an egg levitate, my survival instinct would surely kick in and help me find a solution.

OK boj readers, drop everything and get cracking.

heh
