Intelligent
2 Blue Jays conversing in a spruce. First Jay asks "What if we aren't the only intelligent species in the universe? What would they be like?" The second replies "Let's see... they'd need to be good at problem solving, and to have advanced communication skills, a social structure, self-awareness..." "... the ability to fly?" continues the first Jay. "That goes without saying!" exclaims the second. The first states confidently "And a strong beak, of course". To which the second responds rhetorically "How could you do anything intelligent without a strong beak?"

What makes new goals difficult to reach? As I discussed with @alisonpstevens.bsky.social for @sciencenews.bsky.social, the issue might be holding precise but costly memories of the target. As we internalize rules for what success looks like, goals become more attainable. @annecollins.bsky.social

Big goals can feel overwhelming. Here’s how to stay on track
Aiming for something big? Break that big goal into smaller, manageable steps. Then narrow your focus. This will keep your eyes on the prize.

Happy Darwin Day to those that celebrate! In these handwritten annotations you can see how Darwin was fascinated by dogs
A graphic that days “Happy Darwin Day! Here are some of his handwritten notes about dogs.” There is a picture of the handwritten notes, which are hard to read. There is also a picture of Darwin himself in older age with a long white beard.Here are some things he took note of:
-Dogs were bred for color in Ancient Greece
-Ancient dogs tended to have upright ears rather than hanging ears
-Newfoundlands have partial webbing between their toes
-Native American dogs in Florida resembled wolves
-One pointer once held a point for over an hour
-Native dogs in the Pacific all went extinct

You can specify relative position in ggplot with I(x) I(y). E.g. annotate("text", x = I(.5), y = I(.5), label = "hello!") will place the text in the middle of the plot. This, combined with alignment arguments is like 87% of the magic for me.
