Animal Sleep Most animals have a daily pattern of rest and activity. Some animals are more active during the day (diurnal) and some are more active during the night (nocturnal). How much time do animals spend sleeping? Well, it depends on the animal: References: This table was adapted from four sources: Aserinsky, E., Eyelid condition at birth: relationship to adult mammalian sleep-waking patterns, In Rapid Eye Movement Sleep, edited by B.N.
Outlets of the Future aka in-wall USB Charger 1. Plug the Mini USB chargers into the outlets. Because the USB ports are off center I decided to put them both toward the center. 2. 3. 4. 5. 6. Breathingearth - CO2, birth &death rates by country, simulated real-time Will Life Be Worth Living In 2,000AD? What sort of life will you be living 39 years from now? Scientists have looked into the future and they can tell you. It looks as if everything will be so easy that people will probably die from sheer boredom. You will be whisked around in monorail vehicles at 200 miles an hour and you will think nothing of taking a fortnight's holiday in outer space. Your house will probably have air walls, and a floating roof, adjustable to the angle of the sun. oors will open automatically, and clothing will be put away by remote control. You'll have a home control room - an electronics centre, where messages will be recorded when you're away from home. You'll have wall-to-wall global TV, an indoor swimming pool, TV-telephones and room-to-room TV. The status symbol of the year 2000 will be the home computer help, which will help mother tend the children, cook the meals and issue reminders of appointments. Cooking will be in solar ovens with microwave controls. There's a lot more besides to make H.G.
Imaging maths - Inside the Klein bottle September 2003 My first practical experience with a Klein bottle was a failure. When I was still at school I came across a picture of a Klein bottle in a weekly journal. I shared my fascination with a friend who was a glassmaker specializing in physics equipment for schools. A few days later I was a proud owner of a physical Klein bottle, made of glass. What to do with such a bottle? To my delight, this primitive but interesting thermometer did indeed show signs of life during the day. The Klein bottle was discovered in 1882 by Felix Klein [1] and since then has joined the gallery of popular mathematical shapes known to the general public outside the "ivory tower". From the Möbius band to the projective plane The Möbius band is the simplest one-sided surface, and is easy to make out of a strip of paper. The band was discovered in 1858 by the German astronomer and mathematician August Ferdinand Möbius. Despite its simplicity the Möbius band was a genuine mathematical discovery. Felix Klein

How to boost your WiFi signal with a beer can | TechFlesh- News, Gadgets,... Here you will find very original tips to boost wireless signal to your computer. Good luck and have a fun. Source A beautiful but creepy vision of the "smart glass" future Two things: First, considering the touchscreen maps at my local shopping centres ae almost always down or only half work, and smeared with public finger goop, the maintenance factor would be huge in this kind of world. They'd always need constant repairs, cleaning, and upgrading. And the other thing is, though the touchscreen concept works okay at a small handheld level, if every single button you push has no tactile response, that satisfaction of a physical reaction to pressing a button, it can get quite exhausting for the fingers. Typing, which would be slowed down on a vertical or flat horizontal surface anyway, would be very painful to tap away at, with your fingertips repeatedly hitting solid glass with no give. I can see the small scale, and informative aspect, like temperature gauges on mirrors and windows, or dashboard info on car windscreens, but this kind of epic interactivity just wouldn't work.
Slingshot Instructions: (after you've read these, click here to get a bigger picture.) Click and drag the arrow to change the direction of launch of the spaceship. Choose Jupiter's path distance (the shortest distance of the initial launch point from Jupiter's orbital path) and initial speed of the spaceship. RESET: puts Jupiter into ready position at far left START: Jupiter begins moving at its orbital speed SHOOT: launches the spaceship Zoom in or out to see the full orbit of the spaceship! You can also right-click on the movie and zoom in to get a better view of the objects. Note: Jupiter moves through a distance equal to its diameter in about 3 hours. *** This flashlet demonstrates in a semiquantitative way how a properly directed spaceship can pick up energy from a moving planet.

02002-02029 (27 years): By 2029 no computer - or &machine intelligence& - will have passed the Turing Test. - Long Bets - StumbleUpon The Significance of the Turing Test. The implicit, and in my view brilliant, insight in Turing's eponymous test is the ability of written human language to represent human-level thinking. The basis of the Turing test is that if the human Turing test judge is competent, then an entity requires human-level intelligence in order to pass the test. To the extent that the "AI" chooses to reveal its "history" during the interview with the Turing Test judge (note that none of the contestants are required to reveal their histories), the AI will need to use a fictional human history because "it" will not be in a position to be honest about its origins as a machine intelligence and pass the test. There are many contemporary examples of computers passing "narrow" forms of the Turing test, that is, demonstrating human-level intelligence in specific domains. It is also important to note that once a computer does achieve a human level of intelligence, it will necessarily soar past it.
THINGS YOU LEARN IN COLLEGE & The Career Closet I had to post this hilarious list from www.funny2.com/collegeBut you don’t learn these things in class Quarters are like gold.Flip-flops become as important as soap, and shampoo. Asleep by 2:30 AM is an early night. New additions to the food groups: Mountain Dew, Doritos, Ben & Jerry’s, Ho-Hos and Oreos. Make sure your alarm clock has back-up batteries. Duct tape heals all wounds. Showers become less important. Sleep becomes more important. 10 minutes is more than enough time to get ready for your first class. Going to the mailbox was never an ego-booster (or ego-breaker) before. You begin to nap again. The book your professor wrote is always required for his class. E-mail becomes your second language. Frat parties are exactly like they are in the movies. Ten-page papers used to sound impossible, now they’re a Godsend. You never realized so many people are smarter than you. You never realized so many people are dumber than you. Professors are like celebrities: you see them, but they never see you.
