Perpetual motion machine inventors do have principles. Unfortunately the physical principles they assume are often ones not obeyed by nature. Let's examine just a few. The principle of unlimited possibility. Anything is possible in nature. The "heavier on one side" seduction. Anything is possible Inventors assume that since we haven't looked at every part of the universe nor have we looked at all possible mechanisms or phenomena, we can't rule out anything. Those who think this way are much like the child who puts two blocks in a box, closes the box, shakes it, then opens it, hoping to find three blocks inside. The "heavier on one side" seduction. The most naive level of perpetual motion seduction is the notion that if a system has more mass on one side of the axle, then that side must swing downward. We can test its stability by turning the wheel to any position whatever. The earliest unbalanced wheel of Bhaskara underwent countless modifications and embellishments over centuries.

Immortality blows (fiction) - StumbleUpon Man, I wish I'd never found that goddamn lamp. Stupid fucking genie. I just had to blurt it out, didn't I? "I wish I were immortal!" User:Transfinite/Mecha as Practical War Machines The Land Walker is an example of a real life attempt at creating mecha Mecha as Practical War Machines[edit] The question of whether mecha could ever be used in the real world as practical war machines is a widely debated topic on many mecha forums. Due to their intended purpose, mecha are usually compared to tanks (or, in the case of Gundam or Macross, fighters). Mecha as a Replacement for Tanks[edit] Mobility[edit] Deepak Chopra: Happy Futurism: A Lifeline for Optimists The world is going through a downturn, which doesn't make for happiness, yet I think the larger trends are surprisingly hopeful. News cycles are fueled by bad news, and ratings must be kept up with impending disasters, whatever it takes to keep the tension high. The evening news gives the impression of a world lurching from crisis to crisis, playing brinkmanship ten times a week. This is largely not so, however. Looking at the big picture, we might pre-empt history's negative judgments. At the very least, global events have a good and bad side.

Belief in Nothing - StumbleUpon Nihilism confuses people. "How can you care about anything, or strive for anything, if you believe nothing means anything?" they ask. In return, nihilists point to the assumption of inherent meaning and question that assumption. Do we need existence to mean anything? After all, existence stays out there no matter what we think of it. List of engineering branches Engineering is the discipline, art, and profession that applies scientific theory to design, develop, and analyze technological solutions. In the contemporary era, is generally considered to consist of the major basic branches of chemical engineering, civil engineering, electrical engineering and mechanical engineering.[1] There are numerous other engineering subdisciplines and interdisciplinary subjects that are derived from concentrations, combinations, or extensions of the major engineering branches. Chemical engineering[edit]

Wired 8.04: Why the future doesnt need us. - StumbleUpon Why the future doesn't need us. Our most powerful 21st-century technologies - robotics, genetic engineering, and nanotech - are threatening to make humans an endangered species. From the moment I became involved in the creation of new technologies, their ethical dimensions have concerned me, but it was only in the autumn of 1998 that I became anxiously aware of how great are the dangers facing us in the 21st century. I can date the onset of my unease to the day I met Ray Kurzweil, the deservedly famous inventor of the first reading machine for the blind and many other amazing things.

Recent Database Breaches Teach Security Lessons Gawker, Epsilon, TSS of San Juan offer window into database hacks -- and how to defend against them [Excerpted from "Database Breaches: Lessons Learned From Real-World Attacks," a new report posted this week on Dark Reading's Database Security Tech Center.] If a hack successfully queries and exports hundreds of thousands -- or even millions -- of customers' records, you have a major problem that’s likely to cost your company millions of dollars in notifications, incident investigation/recovery, and lost business. According to the Ponemon Institute’s sixth annual U.S. Cost of a Data Breach Study, data breach incidents cost U.S. companies $214 per compromised customer record in 2010.

Team build worlds smallest hard drive & News in Science (ABC Science) News in Science Friday, 13 January 2012 Jesse EmspakDiscovery News Nano storage Hard drives could one day be the size of rice grains, powering music players so small they would fit inside your ear. Scientists at IBM and the German Center for Free-Electron Laser Science have built the world's smallest unit of magnetic storage, using just 96 atoms to create one byte of data. Conventional drives require a half a billion atoms for each byte. English Pronunciation If you can pronounce correctly every word in this poem, you will be speaking English better than 90% of the native English speakers in the world. After trying the verses, a Frenchman said he’d prefer six months of hard labour to reading six lines aloud. Dearest creature in creation, Study English pronunciation. I will teach you in my verse Sounds like corpse, corps, horse, and worse. I will keep you, Suzy, busy, Make your head with heat grow dizzy.
