The Popular Science archives—Google-digitzed versions of whole issues stretching back to the beginning of the 20th century—will never not be awesome. Reading these magazines can teach you a lot about the culture and history of science. It's also a nice way for journalists, like me, to remind ourselves about how very easy it is to get our jobs wrong.
For instance, just because the Royal Geographic Society is sending an expedition to the Himalayas to hunt for the Abominable Snowman doesn't mean the Abominable Snowman definitely exists. In this story, from a gallery of Pop Sci articles about pseudoscience (some appropriately skeptical, some ... not), it's easy to see the writer getting so caught up in the excitement of the hunt that he stopped questioning whether there was really anything to hunt for. It's a fun read. And a nice kick in the pants.
I’ve had quite a few fun afternoons playing with dry ice from making spooky fog in the kitchen to exploding plastic bottles in the yard. But I’ve never had the opportunity to pour hot lava over dry ice. In this video, the lava is 1400 °C and the dry ice is -78C°. So cool! And […]
A Boston University team have developed an acoustic, 3D-printed metamaterial whose topology is such that it reflects 94% of human-audible sound; the researchers' demonstration involves inserting a ring of this stuff in a PVC pipe and blasting a speaker down one end: light and air emerges from the other end, but sound does not.
Scientists Lior Appelbaum and David Zada in Israel publish new proof that sleep serves to help our brains repair damage.
Big companies want automation on a big scale. Doing that means diving into the tricky world of machine learning and data science. And no matter what platform you’ll be implementing it on, you can learn how with the Machine Learning & Data Science Certification Training Bundle. In 48 hours and through eight courses, this bundle […]
Big systems need tight security – and the experts who can implement it. Cisco Networking Systems are the go-to providers for network infrastructure, but maintaining it takes a lot of up-to-date knowledge. If you want that knowledge right from the source, there’s an online course that can get you certified painlessly: The Foundational Cisco CCNA […]
Computer slowing down? There are a ton of reasons why that might be, especially if your unit has a few years on it. Junk files and programs can accumulate over time, some even left over from otherwise uninstalled software. This virtual debris can slow your PC down dramatically, but there’s a surprisingly quick fix. Lauded […]
