Ich was a burden to plese
Nowe looke arounde
Leaves are broun
And the skye
Ys a hazye shade of wynter

I do love that the arctrig functions do translate to actual arc lengths, though.

How is it that people don't ruin this by just pressing the doorbell any time?

Asteroid 2024 YRβ‚„ will NOT hit the Moon.

JWST observations refined the orbit, dropping the lunar impact probability from 4% to zero.

Independent researcher Sam Deen had already reached the same conclusion using 2016 precoveries.

The problem is not "thinking of it as a person". The problem is "thinking of it as a person that is as competent as it sounds". LLMs are best thought of as a person with poorly understood brain damage.

So with the sugar rush, you probably had some "creative" art ideas .. that you *may* want to look over again the next day before starting them!

sorry, was away from computer .. but aren't there options for particular angle rotations (and .. rotate a circle? won't it still be a circle .. unless there is something else attached to indicate a rotation) (at this point you probably have it solved)

Students are used to measuring degrees so don't get radians. Here are some interesting radian scale protractors https://www.proradian.net/ (by Jennifer Silverman, @jensilvermath)

Sorry I'm not more open-minded about LLMs, it's just some fucking maniacs shoveled out a bunch of useless bloatware featuring that technology, did not give me any chance to opt out, reorganized the entire economy around it, zeroed out gains made by green energy, and made it impossible to buy RAM

Color photo of the Pioneer 10 rocket launch, which took place at night. The photo is dominated by the bright white and yellow glowing exhaust at the bast of the rocket as it lifts off.

A black and white diagram showing the path of Pioneer "F" and "G," later dubbed "10" and "11," through the inner solar system, past the asteroid belt, and to the vicinity of Jupiter. The diagram shows the Sun, Mercury, Venus, Earth, Mars, Pallas, Vesta, Ceres, and Jupiter.

A (vertical) triptych of Jupiter images captured by Pioneer 10. All three photos show white, orange, and tan cloud bands. The Great Red Spot is on the left limb of the planet in the top photo, and moves towards the center in images 2 and 3. In addition, the shadow of an inner moon moves across the face of the planet.

Color image of the anodized aluminum plaque attached to Pioneer 10. It shows line art diagrams of a man and woman, their relative size compared to the probe, a diagram of our solar system with Pioneer's path past Mars and Jupiter then out of the solar system, our location relative to a number of pulsars, and a schematic representation of a well-known Hydrogen atom transition.

Pioneer 10 launched #OTD in 1972.

It was a mission of firsts: passing through the asteroid belt, visiting Jupiter, crossing Neptune's orbit, achieving the speed needed to leave the solar system.

We detected a last, faint signal on January 23, 2003. Now it belongs to the cosmos. πŸ§ͺ πŸ”­ πŸ›°οΈ

Did you know that the bees that need saving are NOT honeybees?

Honeybees are the dairy cows of bees. People brought them over from Europe to make us honey.

The problem with honeybees, esp in resource-limited ecosystems (like hey! cities!) is that they compete with our native bees for food.

I recently got a Cricut, which I haven't had time to try, for cutting fabric (masks/ties), and astronomy "thingies" for my astro class/lab (sundials, etc) .. *and* now I'm looking up circle cutters! All the toys!!! [So, thanks? 🀣]

Watching a TV show and a senior academic has bookshelves in their office with plenty of space for new books. I’m used to suspending disbelief but this is ridiculous.
