The Technological Singularity Continuous Chest Compression CPR—University of Arizona Sarver Heart Center Emotional Freedom Technique (EFT) for Headaches 11 ways you are thoroughly (but interestingly) wrong The folks at Your Logical Fallacy Is have compiled a list of 24 common ways that you and I are often mistaken in the way we think. I have to say that looking through their site is perhaps the most fun I’ve ever had being told how wrong I am. And not just wrong in a certain instance, but consistently and fundamentally flawed in the very way I think. Fun, right? I thought so. Included at the site is a free, very high-res poster for those of you who may have a reason to hang these as a reminder on the wall. (via MetaFilter)
10 Scientific Laws and Theories You Really Should Know" The British physicist and novelist C.P. Snow once said that a nonscientist who didn't know the second law of thermodynamics was like a scientist who had never read Shakespeare [source: Lambert]. Snow's now-famous statement was meant to emphasize both the importance of thermodynamics and the necessity for nonscientists to learn about it. Thermodynamics is the study of how energy works in a system, whether it's an engine or the Earth's core. It can be reduced to several basic laws, which Snow cleverly summed up as follows [source: Physics Planet]: You can't win.You can't break even.You can't quit the game. Let's unpack these a bit. The second statement -- you can't break even -- means that due to ever-increasing entropy, you can't return to the same energy state. Finally, the third law -- you can't quit the game -- refers to absolute zero, the lowest theoretical temperature possible, measured at zero Kelvin or (minus 273.15 degrees Celsius and minus 459.67 degrees Fahrenheit).
How to Navigate by the Stars Explorers have used the stars as a compass for millennia, and if you’re out having adventures at night, you should add the skill to your arsenal. (If nothing else, it’s a killer party trick.) Here’s how to transform the night sky into your personal roadmap. 1) Learn the Big Three According to the Royal Naval Academy, 58 stars are handy for navigation. You need to know 38 different constellations to find all of them. 2) Find the North Star It’s always within one degree of true north. 3) Shoot for the Moon If you can find Orion’s sword, following its point will show you south. 4) Down Under? The North Star isn’t visible below the equator. 5) Move Like a Star Like the sun, stars skate east to west. 6) Take a Survey Forgot to memorize your constellations?
