Twitter's Users Tweet Over 400 Million Times Per Day
I currently follow 159 users on Twitter and I occasionally get overwhelmed by how much they tweet. It's intimidating to imagine that these tweets amount to only a tiny fraction of the 400 million or so tweets generated each day.
Forbes' Tomio Geron reports that Twitter CEO Dick Costolo mentioned the social media network's latest statistics during a talk at a conference organized by the Economist.

My Comment: Only 400 million times a day? I thought it was more.
Stunning New Footage Of Venus Transit
Nasa Releases Stunning New Ultra-High Definition Footage Of 2012 Venus Transit -- The Telegraph
One of the rarest astronomical events is captured on film in stunning detail as the planet Venus passes directly between the Sun and Earth, a transit that won't occur again until 2117.
The amazing video was captured by Nasa's Solar Dynamics Observatory (SDO), the most advanced spacecraft ever designed to study the sun.
On June 5 2012, SDO collected images of the rarest predictable solar event - the transit of Venus across the face of the sun.
This event happens in pairs eight years apart that are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117.

My Comment: Cool video.
Self-Guided Bullet
Straight Shooter Trevor Johnston
Rough Sketch: Self-Guided Bullet -- Popular Science
“Our .50-caliber bullet can guide itself to a hit half a mile away”.
For years, people have tried to come up with ways to steer bullets, and everyone has consistently said you can’t do it. And you couldn’t—if the bullet was spinning. A spinning bullet is too stable; you can’t apply enough force to turn it off its axis of revolution. The secret sauce is that our bullet doesn’t spin. It’s kind of like a musket ball, which doesn’t rotate, but with technology added to let us control where it goes.

Mercedes Embraces More User-Facing Technology
Mercedes Makes the Mundane ‘Magical’ -- Autopia
Leave it to the Germans. Just when you think the most simplistic, mundane bits of a vehicle can’t be improved, they surprise. Such is the case with the 2013 Mercedes-Benz SL550 Roadster, which packs more user-facing technology than this week’s latest and greatest Android device.
But much like the thousands of Android-powered smartphones, Mercedes has a problem with branding. Look no further than the latest technological breakthrough on the SL: Magic Vision Control.

Prelude To A Catastrophe: “One Of The Most Active And Most Explosive Volcanoes In The Cascade Range” -- Scientific American
Imagine being an extraterrestrial geologist in geostationary orbit above the Pacific Northwest in the 1970s. You’re the first explorers to reach Earth (underpants-thieving aliens aside), and you haven’t got a lot of data on this little blue marble. But your own planet has plate tectonics, so you’re familiar with the landforms caused by the process.
You have a look through your sensors, and see a conga line of volcanoes weaving up the continent.

Instead Of Honoring D-Day, Google Honors The Drive-In Theater
D-Day vs The First Drive-In Theater? Google Picks Theater -- Search Engine Roundtable
68 years ago today was one of the most significant days in America's history - D-Day. But 79 years ago today, the first drive in movie theatre opened. Google picked, as it always does, the fun and light hearted even to celebrate with a special Google logo, aka Doodle.
So get past the fact Google doesn't have a logo for D-Day. There is still the concern for some that Google does logos at all on days like today. That is not for me to decide, just to report based on complaints in the forums.

My Comment: I cannot be too critical of Google .... they do focus on the "fun and light hearted". But it would be nice to honor the vets from World War II at least once.
The 2,000-Year-Old Antikythera Computer
The Extraordinary 2,000-Year-Old Computer That You've Never Heard Of -- The Guardian
The Antikythera mechanism was designed to predict movements of the sun, moon and planets. Why isn't it better known?
Right, that's enough of the Queen for now. Have you ever heard of the Antikythera mechanism? You have? Well done. If not, I suspect you're in good company and the fact that I learned about it from a fascinating BBC4 programme – the high point of my jubilee weekend – on Sunday night is unlikely to broaden public knowledge as much as we might hope.

Ancient Man Had A Taste For Sea Food
Catching fish is a practice that goes back thousands of years
World's 'Oldest Fish Trap' Found Off Coast Of Sweden -- BBC
Wooden fish traps said to be some 9,000 years old have been found in the Baltic Sea off Sweden, possibly the oldest such traps in existence.
Marine archaeologists from Stockholm's Sodertorn University found finger-thick hazel rods grouped on the sea bed.
They are thought to be the remains of stationary basket traps.
"This is the world's oldest find when it comes to fishing," said Johan Ronnby, a professor in marine archaeology.

Watch The Venus Transit Online
Missed the Venus Transit in 2012? Watch It Online Until 2117 -- PC World
Did you miss the transit of Venus in front of the sun yesterday? Were there clouds in your skies? Stuck in Antarctica? If you didn’t catch this last alignment of our cloud-shrouded planetary neighbor and our closest star until 2115, here are some ways to re-live the transit.
My favorite video was taken by NASA’s Solar Dynamics Observatory, a spacecraft dedicated to observing the sun. You can watch Venus passing in front of the sun and its giant coronal loops, where plasma moves along the sun’s magnetic field lines.

A Rat Is Still Smarter Than Google
Clever - but still learning: Google Navigation, pictured here on an Android phone, is a clever, intelligent-seeming system - but it is still just code, following instructions
Why Google Is Nowhere Near As Clever As A Rat - But One Day, Even Your Smartphone Will Be Smarter Than You -- Daily Mail
* Clever technology such as Google is still powered by rote-learning and pattern-matching, say AI researchers...
* ...But over the next 30 years, super-computers will become smarter, cheaper, and smaller
Google has spent the last 15 years becoming smarter and smarter, learning how to power our lives - from our homes, our cars, our phones.
But - and with apologies to founders Larry Page and Sergey Brin - all of that work is still no match to the intelligence of a common rat.
Or taking it further, even a gnat.
The point was made by artificial intelligence researchers Yann LeCun and Josh Tenenbaum, who were not criticising the search engine, just pointing out how much further we have to go until we can create computers which contain - or at least, perfectly mimic - intelligent life.

My Comment: We have made progress .... but we definitely still have a long way to go before an AI platform is smarter than a rat.
Robot Ethics: Morals And The Machine
Robot Ethics: Morals And The Machine -- The Economist
As robots grow more autonomous, society needs to develop rules to manage them
IN THE classic science-fiction film “2001”, the ship’s computer, HAL, faces a dilemma. His instructions require him both to fulfil the ship’s mission (investigating an artefact near Jupiter) and to keep the mission’s true purpose secret from the ship’s crew. To resolve the contradiction, he tries to kill the crew.

Every Black Hole Contains a New Universe -- Inside Science
(ISM) -- Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It's a theory that has been explored over the past few decades by a small group of physicists including myself.
Successful as it is, there are notable unsolved questions with the standard big bang theory, which suggests that the universe began as a seemingly impossible "singularity," an infinitely small point containing an infinitely high concentration of matter, expanding in size to what we observe today. The theory of inflation, a super-fast expansion of space proposed in recent decades, fills in many important details, such as why slight lumps in the concentration of matter in the early universe coalesced into large celestial bodies such as galaxies and clusters of galaxies.

ScienceDaily (June 4, 2012) — Giant insects ruled the prehistoric skies during periods when Earth's atmosphere was rich in oxygen. Then came the birds. After the evolution of birds about 150 million years ago, insects got smaller despite rising oxygen levels, according to a new study by scientists at the University of California, Santa Cruz.

Robots Go To War
March Of The Robots -- Economist
Robotics: From reconnaissance to bomb-defusal to launching attacks, military robots are on the march, raising knotty ethical quandaries.
IN THE early afternoon of August 18th 2008, a reconnaissance unit of about 100 French paratroopers, accompanied by a small number of Afghan and American soldiers, was ambushed by a similarly sized Taliban force in the Uzbin Valley, not far from Kabul. Ten French soldiers were killed in fighting that continued into the night—France’s biggest loss since it sent soldiers to Afghanistan in 2002. But it might have been avoided had the unit had a single aerial-robot scout, says Gérard de Boisboissel, a specialist on military robots at the French army’s Saint-Cyr military academy. That assessment, shared by many, led to a retooling of France’s armed forces. Today drones, also called unmanned aerial vehicles (UAVs), routinely accompany even small French units.
