Crescent Moon And Venus

My science teacher writes a joke on this board every week, they are so bad that they are funny and I love it

Photosynthesis is one of those things that you usually learn about in a simplified way when you're little, that we grow up kinda taking for granted that we "know how that works."

But the process is actually so spine tinglingly bizarre, that if you heard about it for the first time as an adult, you wouldn't even believe it.

Plants are just transmuting light beams into highly complex molecules of sugar. By using the light as a fuckin' battering ram to shatter molecules of water apart. And we're just like "oh yeah, they do that, no big deal" as if that's not a seven layer bizarro dip of what the fuck.

AFRICAN PENGUINS IDENTIFY PATNERS BY THEIR CHEST DOTS

Birds are known to be highly social and visual animals, and penguins are not the exception, as they live in dense colonies. Yet no specific visual feature has been identified to be responsible for individual recognition in birds. Now, researchers demonstrate that african penguins (Spheniscus demersus) can recognize their each others using their ventral dot patterns.

Researchers placed a experiment at the Zoomarine Marine Park, in Rome, Italy, to test how penguins will react to a model with plain with no dot penguin, and to penguins with dots, to find out penguins actually could visually recognize the dots of their lovers and friends in the zoo.

Penguins rely strongly on their ventral dot patterns for individual recognition, and may have holistic representations of other penguins in the colony. In this video below, an african penguin named Gerry appears to recognize his mate, Fiorella (left), in an individual recognition experiment.

These findings suggest that african penguins may rely on a more holistic visual representation of their partner, which includes both the ventral dot patterns and their partner's facial features. Notably, these abilities are not dependent on the ability of a pair to produce offspring together. Nemo and Chicco, male partners, showed the same preference for each other as other penguin partner pairs, suggesting that the ability to distinguish the partner from others is driven simply by the special bond developed between nesting partners.

Millipede under UV light. Many species of arthropods fluoresce, or glow, under ultraviolet light due to due to fluorescent compounds in their exoskeletons. At least one millipede genus, motyxia, is actually bioluminescent, meaning it can produce light on its own.

Feelings Wheel❤️

In order to discuss your feelings and emotions, you must know how to appropriately name them.

Putting a name to what you're feeling helps you to gain clarity and move forward with identifying your next step toward healing or resolution 💜

Why did I think anyone would like this?

Hey... what the fuck???

So I read the article, and this is super cool. Basically what happened is that they let a drop of butyl alcohol out from a syringe onto the surface of another liquid, and it just... hung out there? For a very significant amount of time, too. In the past, this type of "droplet levitation" has only lasted a few milliseconds max, but this droplet was staying levitated without any external forces applied for tens of minutes.

The reason this happens is because of Solutocapilllary convection, which as far as I can tell essentially boosts the surface tension of that one spot in the underlying liquid using vapor molecules, so that the butyl alcohol molecule can't sink in.

Also, the reason why I specified that the reason this was cool is because it was done without external forces is that APPARENTLY we've been able to levitate things using sound waves since like... the 1930s. And it makes sense that you can do that, in principle, but it still looks absolutely wild to see.

The more I hear people talk about race, the more I see the need to teach. People actually believe that skin colors represent race for humans without even thinking about it, how dumb and ignorant can humans be?

What in the hell do skin colors have to do with races to start with? I really would appreciate it if people would take the time to educate themselves about scientific racism and teach their children that races don't exist on earth, we are all Black Africans who inhabit earth 🌍.
