EarthViewer for iPad Takes You Through the History of Earth EarthViewer is a free iPad app that takes you through 4.5 billion years on Earth. EarthViewer allows you to select eons and eras to view. Within each eon and era you can view tectonic plates, continental drift, and other geological events. You can view major biological events in EarthViewer too. Climate data for the last one hundred years is available in the app. EarthViewer users can manipulate the virtual globe to see how each continent has moved and been altered over time. EarthViewer could be an excellent resource to include in a science or geography lesson. Tags: biology, free ipad app, free ipad apps, geography, geology, science, science apps
Michael Pecirno's Minimal Maps Single Out American Land Use Patterns Most maps of the U.S. prioritize metropolitan areas. But "Minimal Maps" single out the nation's forests, crops, and waterbodies. Eighty percent of the U.S. population lives in "urban" areas, a staggering 249,253,271 souls. Yet these folks live in just 3 percent of the country's 2.3 billion acres of land. These are statistics that never fail to blow my provincially urban mind—in part, perhaps, because most maps of the country visually prioritize metropolitan areas. But London-based designer Michael Pecirno produces images of America that illuminate all land use patterns, type by type. "[C]orn fields take up 91 million acres of the American landscape," writes Pecirno in an email. All images courtesy of Michael Pecirno.

WWF Together Powers of Minus Ten - Bone Brugstedet.dk PlantNet Identification Plante – Applications sur Google Play Pl@ntNet est une application vous permettant d’identifier les plantes simplement en les photographiant avec votre smartphone. Très utile lorsqu’on n’a pas un botaniste sous la main ! Pl@ntNet, c’est aussi un grand projet de sciences participatives : toutes les plantes que vous photographiez sont collectées et analysées par des scientifiques du monde entier afin de mieux comprendre l’évolution de la biodiversité végétale et de mieux la préserver. Pl@ntNet permet d’identifier et de mieux connaître toutes sortes de plantes vivant dans la nature : des plantes à fleur, des arbres, des herbes, des conifères, des fougères, des lianes, des salades sauvages ou bien encore des cactus. Plus vous donner à Pl@ntNet d’information visuelle sur la plante que vous observez et plus l’identification sera précise. A l’heure actuelle Pl@ntNet permet de reconnaître environ 20 000 espèces. La version web de l’application est également disponible à l’adresse suivante :
Dark Side of the Earth 200 miles above Earth's surface, astronaut Dave Wolf -- rocketing through the blackness of Earth's shadow at 5 miles a second -- floated out of the Mir Space Station on his very first spacewalk. In this short, he describes the extremes of light and dark in space, relives a heart-pounding close call, and shares one of the most tranquil moments of his life. When we were putting together our live show In the Dark, Jad and Robert called up Dave Wolf to ask him if he had any stories about darkness. And boy, did he. Dave told us two stories that became the finale of our show. Back in late 1997, Dave Wolf was on his first spacewalk, to perform work on the Mir (the photo to the right was taken during that mission, courtesy of NASA.). Out in blackness of space, the contrast between light and dark is almost unimaginably extreme -- every 45 minutes, you plunge between absolute darkness on the night-side of Earth, and blazing light as the sun screams into view.
