POPSThe rotating grid illusionby
rj3sp Yesterday 11:51 AM A surprising optical illusion which is related to temporal aliasing, a visual phenomenon also known as the stroboscopic effect, which accounts for the fact that in video or motion pictures, wheels sometimes appear to be turning backwards.

POPSLet's junk the myths and celebrate what we've got Moreover, we need to become responsible versus petty humans; in the words of the article "When you see nothing but junk, create quality. Where quality is hard to find, curate it, adding your own seal of approval with a link. When you read inaccuracies and misunderstandings, add facts, corrections, context and journalism. If people on the internet get things wrong, educate them. When you hear the noise of people talking online, listen." Thumbs up.

POPSSay It Ain't So Pat Pat Robertson, that Nostradamus of the 21st century, has done it again. Although his previous predictions haven't fared all that well there's always a first time. And if his prognostications fail to materialize, there's always the "God works in mysterious ways" get out of jail free card. In conclusion, I'd like to offer my own Elixir of Health and Life Extender. Just send $4.98 to ...

POPSPre Spinning a Palin Loss Wouldn't it be nice if once, just once, somebody actually surprised us? The more I look at our political system the more I need anti-depressants.

POPScentripetal-force spin dryers - gentler & more effective than a wringer I've been feeling increasingly dissatisfied with the laundry facilities in our apartment building, and schlepping everything to the laundromat isn't terribly appealing, either. We've been looking at a hand-cranked tabletop washing machine, and these spin dryers look like one might be a useful addition.

POPSSun May Be Galactic Hitchhiker... Stars could travel from deep within the interior of a galaxy to its outer edges, and might even get passed around in a "spiral arm relay," Roskar told SPACE.com. Our sun currently has an orbit near the outer edge of the galaxy. New simulation runs confirmed earlier work that showed how star orbits can remain circular despite expanding or shrinking. That counters assumptions that the gravitational tug-of-war would push and pull orbits into wilder elliptical shapes.

POPSCloud-seeding ships could combat climate change The 300-tonne unmanned ships used to seed the clouds would be powered by the wind, but would not use conventional sails. Instead they would be fitted with a number of 20 m-high, 2.5 m-diameter cylinders known as “Flettner rotors” that would be made to spin continuously. This spinning would generate a force perpendicular to the wind direction, propelling the ship forward if it is oriented at right angles to the wind. around 1500 ships would be needed altogether to counteract a carbon doubling, at a cost of some £1m to £2m each. This would involve an initial fleet expanding by some 50 ships a year if the scheme is to keep in step with the current rate of increase in atmospheric carbon-dioxide levels.

POPSThe Most Important Story So Far This Month I join you in your anger, disgust and dismay. I'ts the best news corporate can buy! (0.00 / 0) Between this story and the Matthew McConaughey placenta spectacular, I thank God I've lived long enough to remember what journalism used to be. Including the status of our servicemen and women, there are so many issues to be tackled and this...is the best that media can come up with? I'm too flustered to read more than the headlines of this swill. Specifically gave up on network television news 2 years ago...is print next?
