EVOLUTIONARY/GEOLOGICAL TIMELINE v1.0

Melting of the Earth due to radioactive and gravitational heating which leads to its differentiated interior structure as well as outgassing of molecules such as water, methane, ammonia, hydrogen, nitrogen, and carbon dioxide Atmospheric water is photodissociated by ultraviolet light to give oxygen atoms which are incorporated into an ozone layer and hydrogen molecules which escape into space Prokaryotic cell organisms develop Beginning of photosynthesis by blue-green algae which releases oxygen molecules into the atmosphere and steadily works to strengthen the ozone layer and change the Earth's chemically reducing atmosphere into a chemically oxidizing one

The brick-road-laying Tiger Stone - Image 1 of 6

http://www.gizmag.com/tiger-stone-lays-paving-bricks/16951/ Laying down paving bricks is back-breaking, time-consuming work... or at least, it is if you do it the usual way. Henk van Kuijk, director of Dutch industrial company Vanku, evidently decided that squatting/kneeling and shoving the bricks into place on the ground was just a little too slow, so he invented the Tiger Stone paving machine. The road-wide device is fed loose bricks, and lays them out onto the road as it slowly moves along.

Wireless Electricity is Real and Can Change the World

A revolution in the method of transmitting and receiving power is taking place, and the results as it pertains to the everyday consumer may not be far behind. In fact, some forms of the technology will be made available this year. Picture yourself never having to worry about recharging your phone, IPod or laptop as long as you were inside a wireless energy zone. That zone can be located in your house, on the train, in the airport, or at your workplace. “Laptop batteries are always burning out and always need a charge. What we did was build a coil into a standard laptop computer and it gets its source from behind a wall in your office,” said Eric Giler, president and CEO of WiTricity.

6174 (number) - Wikipedia, the free encyclopedia

6174 is known as Kaprekar's constant [ 1 ] [ 2 ] [ 3 ] after the Indian mathematician D. R. Kaprekar . This number is notable for the following property: The above process, known as Kaprekar's routine , will always reach its fixed point , 6174, in at most 7 iterations. [ 4 ] Once 6174 is reached, the process will continue yielding 7641 – 1467 = 6174.
­Millions of people take cruises each year; but when their cruise ends, they usually return to their homes on land. Wouldn't it be great if there were a cruise that never ende­d? That's the basic idea behind a new ocean vessel called Freedom Ship . Unlike a cruise ship, Freedom Ship will be a floating city with permanent residents. The ship will circle the globe every two years and offer everything available in your hometown, including a hospital, college and one of the world's largest shopping malls.
