Troll A is the tallest structure ever moved by mankind.

The Troll A platform has an overall height of 472 metres (1,549 ft) and weighs 683,600 tons (1.2 million tons with ballast).

The platform stands on the sea floor 303 metres (994 feet) below the surface of the sea and one of the continuous-slip-formed concrete cylindrical legs (the leg containing the import and export risers) has an elevator that takes over nine minutes to travel from the platform above the waves to the sea floor.

In a survey of British, American, and German parents, it was found that the happiness that came with the birth of a first child typically reached a high point just before the birth and in the immediate time around it before settling back to pre-child levels.

The same thing happened with the second child, although the spike was less pronounced.

Third children had absolutely no positive effects associated with their arrival, and there were even trends that suggested a downward spiral in happiness in the time after the birth.

Scientists from Seoul National University in South Korea have discovered that cigarette butts can be recycled for use in batteries.

When the butts are put through a thermochemical decomposition process called pyrolysis, the cellulose acetate fibers in the cigarette filters can be made into a carbon-based material used in supercapacitors.

Supercapacitors are innovative batteries that last longer, charge faster, and hold more energy than regular batteries.
