Grinding

Chance The Rapper is facing criticism after a video surfaced of the Chicago rapper dancing with a woman at Jamaica’s Carnival, with some people pointing out that Chance is married.  The video shows Chance enjoying himself at the annual Jamaican festival, with a woman twerking away as he leans back. Chance is also seen slapping the woman’s behind in the clip. As The Neighborhood Talk points out below, some people were quick to suggest that Chance was disrespecting his wife, Kirsten Corley.“Ain’t you married?” one user…

Grinding up old batteries might lead to a low-energy way to recycle the lithium and other metals used in them. Lithum-ion batteries are in all our personal technology — such as phones, laptops and wireless headphones — and they power electric vehicles. Without them, our lives would look very different. The lithium in rechargeable batteries is currently recycled by either heating them to high temperatures or treating them with concentrated acids and organic solvents. Estimates for how much lithium is recycled vary, but…

Coffee Data ScienceDiving deep into how a sifting grinds coffeeIn my many explorations into sifting, I did not consider that the sifter itself could be modifying the coffee grounds. The act of sifting could modify a coffee particle as the grounds are rubbing back and forth. To better understand these theoretical implications, I collected some data.My aim was two folds:Does sifting grind coffee?Does sifting fundamentally change the particle shape?First, I used the Fellow Shimmy to remove less than 300um. Then I sifted the…

AMD has already received much criticism for using a unique design for the integrated heat spreaders (IHS) of its Zen 4 processors. So now enthusiasts are trying to find ways to improve cooling. One of the hacks is to remove the IHS altogether, but a bit less risky method is to reportedly reduce the thickness of the heat spreader by grinding it down.JayzTwoCents (opens in new tab) (via Andreas Schilling (opens in new tab)) grinded off the heat spreader of his Ryzen 9 7950X by 0.8mm and reduced the temperature of the…

Coffee Data ScienceCause and effectI haven’t used a bellows on my other grinders, and I have been hesitant to get one. However, I bought a new grinder (SPK-38G), and it came with a bellows. After using it for a week, I started to wonder what happens if you use the bellows during the grind?What would happen if you continuously bellow throughout the grind? In theory, finer particles that could make it between the burrs would be pushed out sooner, lessening the chances of regrinding.All images by authorI did a test with two…

Container cargo ships sit off shore from the Long Beach/Los Angeles port complex in Long Beach, CA, on Wednesday, October 6, 2021.Jeff Gritchen | MediaNews Group | Getty ImagesArmed with little more than a computer, hackers are increasingly setting their sights on some of the biggest things that humans can build.Vast container ships and chunky freight planes — essential in today's global economy — can now be brought to a halt by a new generation of code warriors."The reality is that an aeroplane or vessel, like any…

Why did people think cannibalism was good for their health? The answer offers a glimpse into the zaniest crannies of European history, at a time when Europeans were obsessed with Egyptian mummies.  Driven first by the belief that ground-up and tinctured human remains could cure anything from bubonic plague to a headache, and then by the macabre ideas Victorian people had about after-dinner entertainment, the bandaged corpses of ancient Egyptians were the subject of fascination from the Middle Ages to the 19th…
