The Mystery of the 'Only Camera to Come Back from the Moon'

Space can be complicated, especially when it's up for sale.
After a furious bidding war in Vienna on Saturday, a Japanese camera collector has bought a Hasselblad camera for $910,000 in a record-setting auction of what's been widely called the "only camera to come back from the moon."
But contrary to claims repeated across the Internet on Monday, this isn't the only camera to come back from the moon.

History of the Rubik's Cube

History 
In 1974, a young Professor of architecture in Budapest (Hungary) named Erno Rubik created an object that was not supposed to be possible. His solid cube twisted and turned - and still it did not break or fall apart. With colourful stickers on its sides, the Cube got scrambled and thus emerged the first “Rubik’s Cube”. It took well over a month for Erno to work out the solution to his puzzle. Little did he expect that Rubik’s Cube would become the world’s best-selling toy ever. As a teacher, Erno was always looking for new, more exciting ways to present information, so he used the Cube’s first model to help him explain to his students about spatial relationships. Erno has always thought of the Cube primarily as an object of art, a mobile sculpture symbolizing stark contrasts of the human condition: bewildering problems and triumphant intelligence; simplicity and complexity; stability and dynamism; order and chaos.For this magic object to become the most popular toy in history a few chance meetings had to take place.

Oak Island Pit Mystery

One of the most curious human-caused mysteries of the past 300 years is the famous “Oak Island Pit” (aka The Money Pit of Oak Island) which has never been fully explained or fully explored, in spite of almost a dozen well-funded excavation attempts using fairly sophisticated equipment and professional engineers.
What has been found is an extremely sophisticated civil engineering project involving multiple lateral tunnels hundreds of feet long that feed sea water into a deep bore tunnel below a depth of about 90 feet.

Bad Karma in the Dharma

When Indian sage guru Padmasambhava, also known as the Second Buddha, prophesied more than one thousand years ago;
‘When the iron bird flies and the horses run on wheels, the Tibetan people will be scattered like ants across the world, and the Dharma will come to the land of the red men (America)’

Electrical Sound Recording


In 1924, J.P. Maxfield and H.C. Harrison of AT&T devised the first recording and reproducing system using electricity. Earlier systems had used direct conversion between sound and mechanical energy only. Photo: Early electrical sound recording machine. Using microphones and amplifiers, they extended the reproducible sound range by more than an octave and appreciably improved fidelity. The recording industry adopted electrical recording in 1925 . Victor records popularized AT&T's technology under the name "Orthophonic."

The Telephone

On March 10, 1876, the telephone was born when Alexander Graham Bell called to his assistant, "Mr. Watson! Come here! I want you!" He was not simply making the first phone call. He was beginning a revolution in communications and commerce. It spread a web of instantaneous information across towns, then a continent, then the world, and has greatly accelerated economic development.

History of mobile phones

Although most of us feel like we couldn't live without our mobile phones, they've not really been in existence for very long. In fact, mobile phones as we know them today have only been around in the last 10 to 15 years.

When was the first mobile phone invented?

Mobile phones, particularly the smartphones that have become our inseparable companions today, are relatively new. However, the origin of the mobile phone goes back to 1908 when a US Patent was issued in Kentucky for a wireless telephone.
The story of the modern mobile phone really begins in the 1940s when engineers working at AT&T developed cells for mobile phone base stations.

Android 0.5, Milestone 5—the land of scrapped interfaces

The first major Android change came three months after the first emulator release: the "m5-rc14" build. Released in February 2008, “Milestone 5" dumped the stretched-out BlackBerry interface and went with a totally revamped design—Google's first attempt at a finger-friendly interface.

This build was still identified as "Android 0.5" in the browser user agent string, but Milestone 5 couldn't be more different from the first release of Android. Several core Android features can directly trace their lineage back to this version. The layout and functionality of the notification panel was

 Android's home screen over the years.
Ron Amadeo
Android has been with us in one form or another for more than six years. During that time, we've seen an absolutely breathtaking rate of change unlike any other development cycle that has ever existed. When it came time for Google to dive in to the smartphone wars, the company took its rapid-iteration, Web-style update cycle and applied it to an operating system, and the result has been an onslaught of continual improvement. Lately, Android has even been running on a previously unheard of six-month development cycle, and that's slower than it used to be. For the first year of Android’s commercial existence, Google was putting out a new version every two-and-a-half months.
