The man who saved the world.
He wasn’t a politician, a scientist, a philosopher, or a university professor. He wasn’t even an American! But had he not had the courage to do what he did, a nuclear war would have happened in 1962.

Fascinating interview, though I find it humorous how it is considered absurd and unlikely for a private company that makes bras to make these spacesuits. In truth, when the Apollo missions happened, Americans had no doubt that ordinary private businesses were the best places to go to get something novel and creative done.

An engineer describes how he and four other engineers debugged a fully fueled Saturn 5 rocket while it was the launchpad.
An engineer describes how he and four other engineers debugged a fully fueled Saturn 5 rocket while it was the launchpad.
The Saturn V was more noisy and ghostly than I had ever expected and it had grown much taller and certainly more threatening since last week. The venting fuel made loud hissing sounds when relief valves popped or opened up suddenly. It was very easy to let your imagination infect your brain. This is a very dangerous place and everything seems to be moving in the heavy foggy mist. There was no way to talk to each other, heck, we could barely see each other and…we hadn’t thought of this problem so we held onto each others yellow protective clothing like kindergartners crossing the street. We all wore safety helmets but they just did not make you feel like you were really safe.
This was also the first test launch of the Saturn 5, so the unknowns were significantly magnified.

The great Martian dust storm of 1971.
The great Martian dust storm of 1971.
There has only been one comparable global dust storm on Mars since then. What made the 1971 even more significant historically is that the first human orbital probe had arrived at that very moment to record it.
By late 1971 and into January 1972 the storm abated, and Mariner 9 began to send back some spectacular images – a total of over 7,300 pictures that mapped the entire martian surface with resolutions ranging from 1 kilometer per pixel to as good at 100 meters per pixel.
The image here gives a sense of the magnitude of the storm. This was what the scientists began to see as the dust settled. The only visible features are the three great Tharsis Montes shield volcanoes, poking up through the haze in a line. The tallest of these reaches an altitude of over 18 kilometers. These peaks, and the enormous bulk of Olympus Mons had never been imaged by a spacecraft before, earlier flybys had missed them.
The late Bruce Murray (Caltech) was on the camera team and recalls, “there was a gradual clearing, like a stage scene, and three dark spots showed up.” The Mars that came out of the storm was a revelation, from these colossal mountains to the great rift of Valles Marineris and the steep valleys of Noctis Labyrinthus.

“Government shuts down, nation descends into riots, looting and cannibalism.”
“The government shut down! We can do anything we like,” shouted Sam Hasbley of Grassley, Iowa, while tearing the tag off a mattress despite an explicit warning label forbidding such a dangerous course of action. “Tear yours off. The government is shut down. It can’t stop you.”
Eyewitnesses spoke of further horrors. On a quiet street in suburban Massachusetts, a man brought out a set of highly illegal lawn darts. In Maryland, there were allegations that an entire family had begun digging ditches to collect rainwater runoff. With the fall of the government, citizen activists took it upon themselves to chronicle the culture of lawlessness. Men played Gibson guitars made of wood imported from India, but not finished by Indian workers. Women bought cold medicine without a photo ID. Children went hours without hearing lectures about the environment.
Heh. Read it all. You will be horrified.

Freeing the Smoky Mountains
The Maddron Bald trailhead on October 3, 2013, during
the government shutdown.
Today we did our last hike in Great Smoky Mountains National Park. As I described yesterday, we decided to go to a place where we could park on private land and easily hike to a trail in the park. That way, we would reduce the level of power any fascist-minded ranger from the National Park Service might have over us should they confront us for being in our park.
As it turns out, there was no evidence at all of a shutdown at the trailhead we choose. We went to the Maddron Bald trailhead, just off state route 321. The parking area here is small, capable of holding no more than 5 or 6 cars. When we arrived there were three cars there, so we had no problem finding room, as you can see from the image to the left.
There were also no signs indicating the park was closed. Nor were there any barricades or cones. As far as we could tell, it was a normal day in the national park, which to me proved that the restrictions the park service is imposing on New Found Gap Road (as well as elsewhere across the nation) has absolutely nothing to do with their lack of funds. This particular trailhead is not as well known or visited, and is off the beaten track. Moreover, it would be hard to monitor. Thus, the park service chose to make believe it wasn’t there. Smart tourists could come here and enjoy the park, as intended, despite the shutdown.
If the shutdown really required the closure of the park, the park service would have sent a ranger here as well. They did not, proving that their obnoxious efforts are really aimed at causing problems for as many Americans as possible, not securing the park as they dishonestly might tell us.

The oldest globe to show the New World may have been discovered.
The globe, about the size of a grapefruit, is labeled in Latin and includes what were considered exotic territories such as Japan, Brazil and Arabia. North America is depicted as a group of scattered islands. The globe’s lone sentence, above the coast of Southeast Asia, is “Hic Sunt Dracones.”
Those words mean, of all things, “Here be dragons.” The globe is dated from 1504, only a dozen years after Columbus’s first voyage.

Scientists have finally discovered the forgotten formula for the concrete the Romans used.
Scientists have finally discovered the forgotten formula for the concrete the Romans used.
The secret to Roman concrete lies in its unique mineral formulation and production technique. As the researchers explain in a press release outlining their findings, “The Romans made concrete by mixing lime and volcanic rock. For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms. The seawater instantly triggered a hot chemical reaction. The lime was hydrated—incorporating water molecules into its structure—and reacted with the ash to cement the whole mixture together.”
The Portland cement formula crucially lacks the lyme and volcanic ash mixture. As a result, it doesn’t bind quite as well when compared with the Roman concrete, researchers found. It is this inferior binding property that explains why structures made of Portland cement tend to weaken and crack after a few decades of use, Jackson says.

And I have a bridge I want to sell you. This story is very suspicious. No picture, the rock isn’t metallic, the NASA engineer who identified it isn’t identified even though he wrote a letter to the man, and it was found on the eastern United States even though Mir was de-orbited over the south Pacific.
If this story is true, than the journalist who wrote it did a really bad job of reporting it.

Tests have now shown that at least one bead from an Egyptian tomb was made from a meteorite.
Tests have now shown that at least one bead of jewelry from an Egyptian tomb was made from a meteorite.
The tube-shaped bead is one of nine found in 1911 in a cemetery at Gerzeh, around 70 kilometres south of Cairo. The cache dates from around 3,300 BC, making the beads the oldest known iron artefacts in Egypt.
An early study found that the iron in the beads had a high nickel content — a signature of iron meteorites — and led to the suggestion that it was of celestial origin2. But scholars argued in the 1980s that accidental early smelting efforts could have led to nickel-enriched iron3, while a more recent analysis of oxidised material on the surface of the beads showed low nickel content4.
To settle the argument, Diane Johnson, a meteorite scientist at the Open University in Milton Keynes, UK, and her colleagues used scanning electron microscopy and computed tomography to analyze one of the beads on loan from the Manchester Museum, UK. The researchers weren’t able to cut the precious artefact open, but they found areas where the weathered material on the surface of the bead had fallen away, providing what Johnson describes as “little windows” to the preserved metal beneath.
The nickel content of this original metal was high — 30% — suggesting that it did indeed come from a meteorite. To confirm the result, the team observed a distinctive crystallographic structure called a Widmanstätten pattern. It is only found in iron meteorites, which cooled extremely slowly inside their parent asteroids as the Solar System was forming.
