The Science Is Clear: Offshore Wind Isn’t What’s Killing Whales

www.scientificamerican.com

"Politicians and nonprofit groups have blamed offshore wind turbines for whale deaths, but the science doesn’t support those claims—at all" "Conducting necropsies on beached whales to pin down a cause of death is made difficult by the animals’ layer of blubber and by the fact that organs can literally cook inside a stranded whale. But it is starkly clear that human activity—in the form of ships that hit whales or fishing gear that wraps around them—is often to blame."

"How I Found A 55 Year Old Bug In The First Lunar Lander Game" by Martin C. Martin

martincmartin.com

cross-posted from: https://lemmy.sdf.org/post/18298626 > "I recently explored the optimal fuel burn schedule to land as gently as possible and with maximum remaining fuel. Surprisingly, the theoretical best strategy didn’t work. The game falsely thinks the lander doesn’t touch down on the surface when in fact it does. Digging in, I was amazed by the sophisticated physics and numerical computing in the game. Eventually I found a bug: a missing “divide by two” that had seemingly gone unnoticed for nearly 55 years."

In 1952, a group of three 'stars' vanished—astronomers still can't find them

phys.org

cross-posted from: https://lemmy.sdf.org/post/6593278 > On July 19, 1952, Palomar Observatory was undertaking a photographic survey of the night sky. Part of the project was to take multiple images of the same region of sky, to help identify things such as asteroids. At around 8:52 that evening a photographic plate captured the light of three stars clustered together. At a magnitude of 15, they were reasonably bright in the image. At 9:45 pm the same region of sky was captured again, but this time the three stars were nowhere to be seen. In less than an hour they had completely vanished.
