One of the more creative hypotheses surrounding quantum mechanics posits the exact opposite. Though we can readily see only one world, quantum mechanics says that when were not observing the particles that make up that world, those particles exist in multiple places at once. There are many theories that attempt to grasp what this means, but one of the most tantalizing is Hugh Everett's multiverse concept.
digg_url = 'http://digg.com/design/Can_a_Swimsuit_Be_Too_Good'; Even we didnt guess it would be this good. When I wrote last month about Speedos latest swimsuit—an extremely high-tech full-body wonder—three world records had already been broken by LZR-clad swimmers. Coincidence? Maybe. But, after eight more records fell in the past month, the suit is causing some serious waves.
Portland is arguably the furthest along of any American city as far as far as bicycle-friendly infrastructure goes (Seattle and Davis are close seconds). But none of them even approaches the level of cultural saturation prevalent in the Netherlands; the grand Mecca of cycle commuting. That is not to imply the American cities' efforts are futile, I mention the disparity only to convey the weight behind a statement this week from the Dutch Cycling Federation calling on the government to mandate the installation of air bags on cars. On the outside.
Used to be, a guy could sit comfortably on the couch and, by mashing a few buttons, make onscreen characters do all the hard work. Nintendo changed all that with the Wii. Suddenly, if you wanted to bowl or play tennis or help Mario save the galaxy, you had to stand up (gasp!) and move major muscle groups in a coordinated manner (heresy!). All those years of disciplined training to develop Thumbs of Steel (and Buns of Marshmallow), and Nintendo changes the game.
The good news is that the ozone hole over Antarctica is slowly healing, thanks to controls on ozone-depleting substances that were once widely used in products such as refrigerators and aerosol cans. Stratospheric ozone protects us from harmful ultraviolet radiation that can cause problems such as skin cancer and crop damage.
Today marks the 18th anniversary of the launch of the Hubble Space Telescope, and to celebrate, NASA has released a collection of 59 new Hubble images (under the fantastic title "Galxies Gone Wild!") that present galaxies in all of their volatile wonder.
Carry a different phone for every situation, whether youre traveling light or blasting tunes in your car. On its own, Modu is one of the smallest, lightest cellphones yet. But when you want to do more than basic calling, pop it into a new outer shell to give it features like a full keyboard, a wider display or a longer-lasting battery.
