Flight 370 mystery: How can a jetliner drop off the radar?

Disappearance of Malaysia Airlines Flight 370 is very puzzling, with no hard evidence at the time of writing. The nearest thing to good news in this matter, is NextGen, a satellite-based aircraft navigation system under development by the FAA. Better tracking, with more accurate navigation in the air & it will get you to the gate faster.

Is the United States an enemy of the Internet?

Reporters Without Borders thinks so. Every year, they publish a list called "Enemies of the Internet". In the latest list, the US joins such champions of freedom as China, North Korea, Saudi Arabia, Cuba & Iran.

Amazing monumental public art from Vancouver – Kickstarter (video)


Credit: Moshi/The Gadgeteer

Kickstarter makes amazing things happen by connecting people with an idea to people who want to support it financially. Total recently passed $US1 billion pledged by 5.7 million people. Projects have included plays, books & hardware. I was a backer of the Pebble smart watch. Very happy with it.

To quote Neil Gaiman, it has "... a sort of weird & lovely magic ..."

Speaking of which, have a look at this:

Life expectancy: Country vs. City

You may have read in these pages, in July 2013, about lower life expectancy in country areas of the United States.

Something similar happens in Australia too:

Formula 1 – major revisions for 2014 (video)


Red Bull 2014 F1 car — notice the lower nose
Credit: Red Bull

This weekend, the first Formula One race for 2014 will be held in Melbourne Australia. Major revisions to the cars for 2014:

● 1.6 litre 90 degree V6
● turbocharged
● restricted to 15,000 rpm
● tightened regs for crankshaft design, including 3 pin crank — purpose, aparently, is to restrict R&D in this area, & ultimately, cost
● 8 speed semi automatic gearbox — restricted to one set of ratios plus one change through the season without penalty
● individual engines must last for at least 4,000 km (2,485 miles) — 2013 engines had to last for just 2,000 km (1,242 miles)
● lower nose & other body changes to increase safety & reduce downforce
● an additional Energy Recovery System (ERS), turns waste heat energy in the exhaust into electricity, which is available to power the vehicle
● KERS (Kinetic Energy Recovery System) is retained & will be renamed ERS-K

How wind helps Antarctic sea ice grow, even as the Arctic melts


Credit: Mark Brandon/Flickr/The Conversation

Both the atmosphere & the oceans are heat engines. I.e. heat from the Sun provides energy to drive winds in the atmosphere & currents in the ocean. By these means, heat is redistributed around the globe. E.g., the climate of Western & Northern Europe is warmer than it would otherwise be, due to the North Atlantic drift, one of the branches of the Gulf Stream.

In the Antarctic, winds, intensified by global warming, are driving an expansion in sea ice:
