In 1910, Walter Goodacre published a map of the Moon, created over the course of several decades using nothing more high-tech than a good quality backyard telescope. Goodacre was an amateur astronomer. He didn't have access to top-of-the-line observatory. But he did have a knack for detail and willingness to painstakingly record his observations of the Moon with pen and paper, eventually producing a map that's accurate to a few kilometers. (In contrast, the high-definition images that we get today from lunar orbiters show details at a scale of a few meters.)
University College London has an explorable version of Goodacre's map on their website, along with scans from his 1910 book that broke the map up into sections. (As art, the sections are almost more intriguing than the full, stitched-together image.) It's all part of a larger collection of historic space images, photos from the Moon, Mars, Jupiter, and Venus.
To demonstrate the Magnus effect, YouTuber PeterSripol grabbed a couple of KFC buckets and tricked out an RC plane. The resulting trial and error is mostly the latter.
One of the weirdest places in Antarctica is Blood Falls, a five-story cascade of blood-red liquid pouring from Taylor Glacier. Researchers finally traced its source: a saltwater lake millions of years old trapped under the glacier.
Fetal lambs survived for weeks in an experimental artificial womb, and scientists hope that the breakthrough could lead to new treatments for premature babies and perhaps the dreamed-of machine utopia where humans are kept mindlessly writhing in translucent plastic sheaths filled with psuedoamniotic liquid. Physicians at the Children’s Hospital of Philadelphia placed fetal lambs into […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
