This mesmerizing phenomenon occurs because liquid oxygen is highly paramagnetic (attracted to magnets), and it boils at an incredibly low temperature, roughly 200°C colder than room temperature. This massive temperature difference triggers the Leidenfrost effect, where the liquid oxygen instantly vaporizes upon contact with a warmer surface, creating a protective cushion of gas that allows the droplet to "dance" or skate across the surface without friction.

What's that sound? Oh yeah it's the sound of freshly mowed grass! Finally made a system that uses Metadata assigned to materials in Blender to differentiate footstep sounds based on surface! #LegionofHonorGame #GodotEngine #indiedev #retro #PSX #WWII #indie #dev

We were showing new staff members the benefit that fans can provide during these “dog days of summer.” This is a FLIR video I took a few seasons ago. You can see the surface temperature drop as the fan blows air across the surface. Without the fan, the surface temperature was well over 100 degrees. #fairview #summer #golf #golfcoursemaintenance #fans #summergolf #greenwich

New research claims human emissions are not driving atmospheric CO2. A paper by Dai Ato ran multiple linear regressions for 1959 to 2022, testing two predictors of the annual CO2 increase: sea surface temperature and human emissions. The result was clear: when the oceans warmed, CO2 levels rose almost exactly in step - about two to three parts per million for every one degree Celsius of warming. Adding human emissions to the model didn't change the outcome. Using only ocean temperature, the model reproduced global CO2 levels with near-perfect accuracy - a correlation of 0.995 and an error of just one to two ppm by 2022. The main factor governing the annual increase in atmospheric CO2 concentration is sea surface temperature rather than human emissions. Earlier studies have shown the same pattern. Temperature changes first, CO2 follows. If Ato is correct, cutting human emissions won't lower atmospheric CO2 because it's the oceans that set the pace.

Galileo was sentenced to house arrest until his death for challenging the idea that the Earth isn’t the center of the universe. 400 years from now, I wonder if people will look back & laugh at the idea that in 2024 people thought a tiny increase in Earth’s surface temperature would be a threat to humanity.

Russian Telegram channels report that the ammunition warehouse in Voronezh region of Russia that was attacked by drones last night, stored surface-to-surface and surface-to-air missiles, shells for tanks and artillery, boxes of ammunition for firearms, etc. From there, they were supplied to the Russian military on the frontlines.

Watch how this guy uses his knife. He uses one or two motions to glide the blade through the meat. When you saw back and forth, it will leave hesitation marks on the surface of the steak. A completely smooth surface is the signature of a pro. Source: carnesboiverde (IG)
