What the Earth Would Look Like If We Drained the Water from the Oceans

Formerly a NASA Fellow at the Goddard Space Flight Center, Dr James O'Donoghue now works as a planetary scientist at the Japanese space agency JAXA. He also hosts a video channel on YouTube. Above, you can watch his high-res remake of a NASA animation produced back in 2008. Here's how NASA framed the original clip:

Three fifths of the Earth's surface is under the ocean, and the ocean floor is as rich in detail as the land surface with which we are familiar. This animation simulates a drop in sea level that gradually reveals this detail. As the sea level drops, the continental shelves appear immediately. They are mostly visible by a depth of 140 meters, except for the Arctic and Antarctic regions, where the shelves are deeper. The mid-ocean ridges start to appear at a depth of 2000 to 3000 meters. By 6000 meters, most of the ocean is drained except for the deep ocean trenches, the deepest of which is the Marianas Trench at a depth of 10,911 meters.

In 51 seconds, watch and see where the great draining ends...

What Voltaire Meant When He Said That “We Must Cultivate Our Garden”: An Animated Introduction

“Voltaire’s goal in writing [his 1759 satire Candide ] was to destroy the optimism of his times,” says Alain de Botton in the School of Life video above, “an optimism that centered around science, love, technical progress, and a faith in reason.” These beliefs were folly, Voltaire thought: the transfer of faith from a providential God to a perfect, clockwork universe. Candide satirizes this happy rationalism in Doctor Pangloss, whose belief that ours is the best of possible worlds comes directly from the philosophical optimism of Gottfried Leibniz . The preponderance of the evidence, Voltaire made abundantly clear in the novel’s series of increasingly horrific episodes, points toward a blind, indifferent universe full of needless cruelty and chaos. “Hope was, he felt, a disease,” de Botton says, and “it was Voltaire’s generous goal to try and cure us of it.” But as everyone who has read Candide (or read a summary or brief notes on Candide ) knows, the novel does not end with ...

An Interactive Map of Odysseus’ 10-Year Journey in Homer’s Odyssey

The Odyssey , one of Homer's two great epics, narrates Odysseus' long, strange trip home after the Trojan war . During their ten-year journey, Odysseus and his men had to overcome divine and natural forces, from battering storms and winds to difficult encounters with the Cyclops Polyphemus, the cannibalistic Laestrygones, the witch-goddess Circe and the rest. And they took a most circuitous route, bouncing all over the Mediterranean, moving first down to Crete and Tunisia. Next over to Sicily, then off toward Spain, and back to Greece again. If you're looking for an easy way to visualize all of the twists and turns in The Odyssey , then we'd recommend spending some time with the interactive map created by Gisèle Mounzer . "Odysseus' Journey" breaks down Odysseus' voyage into 14 key scenes and locates them on a modern map designed by Esri, a company that creates GIS mapping software. Meanwhile, if you're interested in the whole concept of ...

When Albert Einstein & Charlie Chaplin Met and Became Fast Famous Friends (1930)

Photo via Wikimedia Commons “You do not really understand something unless you can explain it to your grandmother,” goes a well-known quote attributed variously to Albert Einstein, Richard Feynman, and Ernest Rutherford. No matter who said it, “the sentiment… rings true,” writes Michelle Lavery , “for researchers in all disciplines from particle physics to ecopsychology.” As Feynman discovered during his many years of teaching , it could be “the motto of all professional communicators,” The Guardian ’s Russell Grossman writes , “and especially those who earn a living communicating the tricky business of science.” Einstein became one of the world’s great science communicators by choice, not necessity, and found ways to explain his complex theories to children and the elderly alike. But perhaps, if he’d had his way, he would rather have avoided words altogether, and preferred acrobatic feats of silent daring to get his message across. We might at least conclude so from his reverence f...
