Plumbata are substantial war darts that have their origins in Ancient Greece and were favoured by late Empire Romans. They have rather nasty barbed head, a lead weight for inertia and were thrown as fighting lines started to close. Their nickname amongst the Romans was Little barbs of Mars

The Roadmachines Mono-Rail may have been the only truly useful, fit-for-purpose monorail in the world. Of the hundreds that were built, most were never meant for passengers. But they did carry a couple of famous people in their time, including a certain secret agent…
Thank you to the staff and volunteers at the Amberley Museum — Harry and Gerry in particular — for running the monorail specially, and letting me film! The Amberley Museum is a massive industrial heritage museum in the South Downs, and you can find out more about them here — via Youtube
A secret cabal is taking over the world. They kidnap children, slaughter, and eat them to gain power from their blood. They control high positions in government, banks, international finance, the news media, and the church. They want to disarm the police. They promote homosexuality and pedophilia. They plan to mongrelize the white race so it will lose its essential power.
Does this conspiracy theory sound familiar? It is. The same narrative has been repackaged by QAnon.
I have studied and worked to prevent genocide for forty years. Genocide Watch and the Alliance Against Genocide, the first international anti-genocide coalition, see such hate-filled conspiracy theories as early warning signs of deadly genocidal violence.
The plot, described above, was the conspiracy revealed
in the most influential anti-Jewish pamphlet of all time. It was called The Protocols of the Elders of Zion. It was written by Russian anti-Jewish propagandists around 1902. It collected myths about a Jewish plot to take over the world that had existed for hundreds of years — via Just Security

Antikythera Fragment #2 – Ancient Tool Technology – The Original Dividing Plate?
One thing about this machine that is truly surprising, is just how small the teeth are.
There’s a well established theory as to how the tooth divisions were marked out, but employing that process to mark out multiple wheels has forced Clickspring to question whether it can reasonably be applied to the Antikythera Mechanism.
So in this video Clickspring proposes an alternative process of wheel division, using only the non precision tools of the period — via Youtube

Every hardcore band you loved in the ’80s and beyond, from Black Flag to Minutemen to Fugazi, had one unfortunate thing in common: Nazi skinheads occasionally stormed their concerts, stomped their fans, gave Hitler salutes in lieu of applauding, and generally turned a communal experience into one full of hatred and conflict. Punk rockers had flirted with fascist imagery for shock value, with the Sex Pistols’ Sid Vicious and Siouxsie Sioux wearing swastikas in public, but, as early San Francisco scenester Howie Klein, later president of Reprise Records, recalls: Suddenly, you had people who were part of the scene who didn’t understand
fascist bad.
By 1980, a more violent strain of punk fans was infecting punk shows. Pogoing became slam-dancing, now known as moshing, and some of ’em didn’t seem like they were there to enjoy the music, as much as they were there to beat up on people — sometimes in a really chickenshit way,
says Jello Biafra, whose band, Dead Kennedys, put out a classic song about it in 1981: Nazi Punks Fuck Off

Steve McQueen made one last effort to buy his favourite Mustang in 1977. He sent a letter, typed on a single piece of heavy off-white vellum, to the car’s owner in New Jersey. The logo for his movie company, Solar Productions, was embossed in the upper left corner and opposite that resided the date, 14 December 1977. The letter is just four sentences.
Again,
it begins, I would like to appeal to you to get back my ’68 Mustang.
McQueen offered no specifics as to why this particular Ford was important to him, except to say that he wanted to keep it unrestored and that it was simply personal with me
.
McQueen’s star may have dimmed by 1977, but he remained an icon, a rare actor loved by both genders. McQueen was also one of us, an aficionado and a racer, someone who understood the instinctual joy of automobiles and motorcycles and indulged in both. And with that ’68 Mustang, McQueen gave us a gift, one of the greatest car chases ever filmed, a duel with a Dodge Charger up, down, and around San Francisco. The Bullitt chase is coveted for the usual crashes and jumps, but it had something more: Unlike most cinematic chases that feature cars performing impossible feats, the one from Bullitt was every bit as exciting, but the driving was obviously real. Those who know cars knew. It’s 10 minutes of film nirvana. McQueen wanted the Bullitt Mustang back.
The rich and famous are often allergic to the word no
, and so was McQueen. His impatience over being rebuked in his quest emerged in the last sentence: I would be happy to try to find you another Mustang similar to the one you have, he wrote, if there is not too much monies involved in it. Otherwise, we had better forget it.
The owner was just fine with forgetting it, and then the Bullitt Mustang made an exit, stage left, from recorded history — via Hagerty

The man who wrote the Australian Antarctic manual for husky team training has welcomed the commemoration of the dogs’ critical roles on maps.
The Antarctic Place Names Committee is naming 26 islands, rocks and reefs after the beloved dogs, that were depended on during Australia’s heroic era of ice exploration a century ago, and had a role into the 1990s.
The dogs were all on Douglas Mawson’s Australasian Antarctic Expedition (AAE) of 1911-14, but the naming is a tribute to all the huskies that underpinned Australian exploration in the icy continent — via ABC News

A pair of Apollo-era NASA computers and hundreds of mysterious tape reels have been discovered in a deceased engineer’s basement in Pittsburgh, according to a NASA Office of the Inspector General (OIG) report released in response to a Freedom of Information Act (FOIA) request.
Most of the tapes are unmarked, but the majority of the rest appear to be instrumentation reels for Pioneer 10 and Pioneer 11, NASA’s fly-by missions to Jupiter and Saturn.
The two computers are so heavy that a crane was likely used to move the machines, the report concluded.
At some point in the early 1970s, an IBM engineer working for NASA at the height of the Space Race took home the computers — and the mysterious tape reels. A scrap dealer, invited to clean out the deceased’s electronics-filled basement, discovered the computers. The devices were clearly labelled NASA PROPERTY
, so the dealer called NASA to report the find.
Please tell NASA these items were not stolen,
the engineer’s heir told the scrap dealer, according to the report. They belonged to IBM Allegheny Center Pittsburgh, PA 15212. During the 1968-1972 timeframe, IBM was getting rid of the items so [redacted engineer] asked if he could have them and was told he could have them.

Ancient Roman concrete marine structures built thousands of years ago are stronger now than when they were first built.
So how has Roman concrete outlasted the empire, while modern concrete mixtures erode within decades of being exposed to seawater?
Scientists have uncovered the chemistry behind how Roman sea walls and harbour piers resisted the elements, and what modern engineers could learn from it.
Romans built their sea walls from a mixture of lime (calcium oxide), volcanic rocks and volcanic ash, a study, published in the journal American Mineralogist, found.
Elements within the volcanic material reacted with sea water to strengthen the concrete structure and prevent cracks from growing over time.
It’s the most durable building material in human history, and I say that as an engineer not prone to hyperbole,

Archaeologists investigating human bones excavated from the deserted mediaeval village of Wharram Percy in North Yorkshire have suggested that the villagers burned and mutilated corpses to prevent the dead from rising from their graves to terrorise the living.
Although starvation cannibalism often accounts for the mutilation of corpses during the Middle Ages, when famines were common, researchers from Historic England and the University of Southampton have found that the ways in which the Wharram Perry remains had been dismembered suggested actions more significant of folk beliefs about preventing the dead from going walkabout.
Their paper, titled A multidisciplinary study of a burnt and mutilated assemblage of human remains from a deserted mediaeval village in England, is published today in the Journal of Archaeological Science — via redwolf.newsvine.com

GUARD Archaeologists have recently recovered a very rare and internationally significant hoard of metalwork that is a major addition to Scottish Late Bronze Age archaeology.
A bronze spearhead decorated with gold was found alongside a bronze sword, pin and scabbard fittings in a pit close to a Bronze Age settlement excavated by a team of GUARD Archaeologists led by Alan Hunter Blair, on behalf of Angus Council in advance of their development of two football pitches at Carnoustie.
Each individual object in the hoard is significant but the presence of gold ornament on the spearhead makes this an exceptional group. Within Britain and Ireland, only a handful of such spearheads are known — among them a weapon hoard found in 1963 at Pyotdykes Farm to the west of Dundee. These two weapon hoards from Angus — found only a few kilometres apart — hint at the wealth of the local warrior society during the centuries around 1000-800 BC — via redwolf.newsvine.com
