Essence of linear algebra - "[Grant Sanderson of 3Blue1Brown (now at Khan Academy) animates] the geometric intuitions underlying linear algebra, making the many matrix and vector operations feel less arbitrary." [more inside]
Alright sir, if you don't get on oxygen you're going to die. [YT] Destin Sandlin of "Smarter Every Day" goes into a high altitude simulation chamber where he demonstrates why you should definitely, always, put on your own oxygen mask first. The chamber is set to the equivalent of 25,000 feet (7,620 meters) after a slow decompression, which allows 3 to 5 minutes of consciousness. The video points out that "most airliners travel at 35,000 feet" (10,670 meters), and under a real scenario you may get only 15-30 seconds of useful consciousness.

Yesterday, during the pre-World Cup friendly between England and Peru being played at Wembley Stadium, there were three goals scored, but the moment that captured the most attention has been this unbelievable, incredible paper airplane toss.
On September 20, 1956, just before the bars closed at 3 a.m., a single-engine plane landed on St. Nicholas Avenue near 191st Street in northern Manhattan. Behind the stick was 26-year-old Tommy Fiztpatrick, who pulled off the no-lights, no-radio "feat of aeronautics" while (allegedly) drunk to (allegedly) win a bar bet. Two years later, when a fellow patron called his story into question, Fitzpatrick did it again.

How airplanes pulling banners take off. (With wonderful MSPaint style illustrations.) Short video showing how it's done. You can hire companies to fly most any banner, of course. The pickup move is risky, so some types of banners can be directly taken off with, because of wheels (that from Wikipedia).

"We finally flew our first thermal camera flight yesterday afternoon. About 10 seconds after launch my co pilot looked at the screen and said something like, 'We now have our very own predator drone'" A rice farmer in Louisiana had a real problem, feral pigs were coming out of the woods at night, into the rice fields, tearing up his crops and causing thousands of dollars worth of damage. The only solution is to bring in hunters to shoot the pigs. Hunting feral pigs in waist high rice plants, in the dead of night, is very difficult. You have to be within 10 feet of them to shoot them and it can take hours to stalk them down. So the farmer calls his brother, an Electronic Warfare engineer who flies RC airplanes as a hobby. $5000 worth of electronics, including a $4500 infrared camera, are installed on a $80 model airplane, and the Dehogaflier is born!

It may take years, but some researcher will travel to Pakistan’s tribal areas and produce a definitive study on what it’s been like to live amidst an aerial bombardment from American pilotless aircraft. When that account inevitably comes out, it’s likely to find that 2010 — and especially the final quarter of 2010 — marked a turning point in how civilians coped with a drone war that turned relentless.

“It’s weird. You only see this type of stuff in movies. Just as long as we're here, I'm sure there are other things somewhere." In the past couple of months, strange blue lights have been appearing over towns across the USA: Anaheim, College Station, and outside of Washington DC. Many UFO buffs and conspiracy theorists believe this to be a part of an alien agenda to force the US Government to disclose alien existence, or perhaps a plot by NASA to overthrow all the world's religions.

Reconnaissance will outlive the U-2, but there will always be a divot in the hearts of those who have seen the curvature of the earth, the stars seemingly close enough to touch, and known the satisfaction of having completed a mission with the Dragon Lady. Former U-2 pilot and military correspondent Cholene Espinoza writes a lovely adieu to these beautiful, difficult-to-fly aircraft, as well as a requiem for the era of human pilots for surveillance, giving way now to UAVs and other remote-control drones. The U-2 is, amazingly, still in service, but apparently soon to be grounded -- or not -- half-a-century after Francis Gary Powers' little Cold War incident. [Previously]

Early in the days of exploration of Antarctica, Australian geologist Douglas Mawson turned down an invitation to join Robert Falcon Scott's Terra Nova Expedition in 1910 (Cool Antarctica previously). Instead, Mawson lead his own expedition, the Australasian Antarctic Expedition (December 1911 to December 1913), an expedition to chart the 2000-mile coastline directly south of Australia, one of the least-visited parts of the continent throughout the early years of Antarctic exploration. The group's efforts and activities are well documented, and many remnants of the expedition remain on Antarctica. The conservation of Mawson's Huts is now an ongoing effort from Association of Australasian Palaeontologists (AAP) Mawson's Huts Foundation. While most efforts were focused on the recovery and treatment of artifacts inside the main hut, the group also searched for the Vickers (Aviation) monoplane that was modified to become an "air tractor", or motorized sledge. The remains of the plane were last seen in 1975. Now the plane has been found, thanks to an exceptionally low tide and a bit of luck. [more inside]

The Kalinin K-7 was a giant flying fortress that might have redefined aerial combat in the 1930s. The hugely expensive and trouble-prone prototype was scrapped by Stalin and its designer was later executed. Here are some renderings of the planes that might have been, with spacious lounges, battleship-sized cannons, and the ability to defend us from UFOs.
