The mineral origin of Stonehenge is an ancient mystery now solved, thanks to the solving of more contemporary one: who absconded with core samples from a crumbling standing stone, drilled out in 1959 so it could be reinforced with rebar?
One of the three cores was recently returned by an 89-year-old worker from the diamond company that performed the work six decades ago, and tests show that it came from a quarry only 15 miles north of the monument.
Researchers first carried out x-ray fluorescence testing of all the remaining sarsens at Stonehenge which revealed most shared a similar chemistry and came from the same area.
They then analysed sarsen outcrops from Norfolk to Devon and compared their chemical composition with the chemistry of a piece of the returned core.
English Heritage said the opportunity to do a destructive test on the core proved "decisive", as it showed its composition matched the chemistry of sarsens at West Woods, just south of Marlborough.
Stonehenge's smaller bluestones were already proven to be from a quarry in Wales. Their 142-mile journey probably involved a leg by boat, a logistical feat that would have been much more challenging for the larger cuts.
History professor Albert Broussard, who also writes a history textbook commonly used in US middle and high schools, is pushing to capitalize the letter “b” in Black in future revisions of the text when referencing Black people. The publisher, McGraw Hill, told CNN that they are “strongly considering it.” From CNN: “I just personally would […]
Denis Shiryaev writes that this footage, filmed in Tokyo between 1913-1915 as “Japan of Today”, was upscaled using neural networks. ✔ FPS boosted to 60 frames per second, I have also fixed some playback speed issues; ✔ Faces are enhanced too – I have added to the pipeline of algorithms a neural network which is […]
Blue from Overly Sarcastic Productions dives into how the Black Death spread from the Mongol Empire throughout Europe, giving us newly relevant terms like “quarantine” and “yeet.” OK, maybe not the latter, but its use in this video to describe pestilence-filled corpses catapulted into Caffa is in fact, perfect.
If you’re a photographer, videographer, or graphic designer, you’ve got a lot of competition charging up behind you. Because while you’ve been trained as a content creator, the task of snapping brilliant images, capturing well-composed video, and posting effective social media is now part of literally everyone’s skill set. For years, Adobe and their ubiquitous […]
After years of hearing a steady drumbeat about the necessity of surfing the web under the protection of a VPN, even the most technophobic among us are starting to come around. But even knowing the dangers one can face from cybercrooks phishing for information from unsuspecting victims online, those last holdouts still have some fears. […]
You may not realize it, but some of the biggest films in movie history have been edited using the same tools some of you use to cut your video of vacationing at Disney World. Giant movies from Oscar favorites The Social Network and Gone Girl to blockbusters like Avatar, Deadpool, and last year’s Terminator: Dark […]
