6:21 PM | A physicist flirts with philosophy (and lives to tell the tale)

Five years ago, I wouldn’t touch philosophy with a barge pole. I was nearing the end of my physics degree, and this had provided me with an adequate enough explanation of the workings of the cosmos. Philosophy, in my view, was obsolete – important to the Ancient Greeks, but of about as much use today [...]

Did you like this photo? No, really like…

Researchers in Germany and the US have developed an algorithm that can work out whether comments on a photo or video (and eventually any shared digital document) are being positive or negative about the quality of the photo, or critical about the subject of the photo itself. So a blurry, underexposed snap of Justin Bieber [...]Related Posts:Media, marketing, mutualitySaving power on the cloudDoubling broadband brings 0.3% economic “boost”Wikimaps plots important points on Wikipedia8 […]

A Little News, Two Approximations, And A Few Graphical Derivatives To Go With Your Coffee

Good Morning! While drinking my coffee after getting a full night's sleep, (hooray for happily sleeping seven month olds!!!), I came across a cute little satellite and some useful approximations.ESTCUBE 1The Estonian University of Tartu has successfully placed a student built and student operated cubesat into orbit. The satellite will deploy an electrodynamic tether and test the ability of the device to propel the space craft by exploiting the force between the electric charge […]

Ants Reveal How to Build a Tunnel You Can't Fall Down

It's hard to keep your footing in a steep tunnel made of loose dirt while others are scrambling around and over your body. Harder still in pitch blackness. That's why fire ants build tunnels that will catch them when they fall—a strategy human engineers might want to steal. "Slips and missteps are likely a constant, recurring feature of life underground," says Nick Gravish, a graduate student in Daniel Goldman's rheology and biomechanics lab at Georgia Tech. Yet ants have to traverse […]

Algae Can Cover One-Twelfth of U.S. Annual Fuel Consumption

A new study shows that the U.S. land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons (94.6 million m3) of algae-based renewable biodiesel a year, one-twelfth of the country’s yearly needs. Read more »
