Felt cute, might delete later. 😊 Morning walk picture. Calling this the Dad Punk aesthetic. 😁 #Curbfind #Dadpunk #Flowers

Aurora video from last night. Over looking the battleship NC in Wilmington NC. At its brightest it was naked eye visible. #Aurora

Predictably, the narwhal situation has escalated. 🧶

Giant cardioid: version 2.5. Version 1.0 was made using Pex tubing and grommet tape. Version 2.0 was made from laser-cut pieces. The wood was too fragile, and it broke during construction. In version 2.5, I made the pieces wider and I used thicker wood. Success, I'd say! The diameter is about 5 ft.

Whoa!

Interesting, just goes to show you that you should remain skeptical of initial reported information as often as not, it will likely contain incorrect facts. Don't just jump to preconceived biases. In this day and age information spreads so quickly that it is both a blessing and a curse.

Meanwhile on Mars... The planet is covered with odd gullies that look like they were carved by running water. A cool new experiment demonstrates that they were probably carved by sliding, spitting chunks of dry ice. (Sorry, still no signs of life.) 🧪🔭 www.uu.nl/en/news/myst...

:My brain: Chemistry Degree: Helium has a full valance shell of electrons and is a very unreactive Noble gas. Physics Degree: ☝️ Actually, if Helium reaches a high enough density and temp (~1M K) it can undergo fusion and release a tremendous amount of energy. 💥 🤓 #Chemsky #Astrophysics

@zohrankmamdani is a deeply thoughtful human being and we think he would make the best NYC mayor imaginable. We feel this as New Yorkers, as Jews and as human beings who are desperate for kindness, compassion and empathy to be represented in our politics. GET OUT THE VOTE here bit.ly/4nxYXFp

Two shrines to the God of Fantasy Fiction! A complicated design and altar piece for those who like me, cannot consume enough fantasy books. I just finished Alchemised by SenLinYu, which was genuinely brilliant and would definitely recommend. www.martintomsky.com/shop/god-of-... #art #fantasy

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

Well, if you ever wanted to see 48 sea monsters hanging out... 🧶

I wonder if the 100K blockers includes blocks from people using block lists? If not, the number could be much higher. I looked and the account is block for me because of a block list I subscribe to. (Right wing propaganda and their followers)

I just learned about a creature called the Conehead Mantis, and it is legit an alien. It would be the stuff of nightmares to be the prey of this thing, caught in its raptorial claws and then munched on by this face. JFC, nature is metal AF. 📸 F. Vassen / R. B. Casado / D. Descouens

Wait...he's set to play Skeletor in a Masters of the Universe movie? I mean, they are seriously making a Masters of the Universe movie? 🤦‍♂️

Frist time I've seen HiRes images of this phenomenon. Pretty cool.

It's mushroom season in the Northern Hemisphere 🍄 Here's a look at the chemistry of arguably the most iconic mushroom, fly agaric, and what makes them so brightly coloured and hallucinogenic: www.compoundchem.com/2024/11/11/f... #ChemSky 🧪

Astonishing indeed. 😮 "neutrino’s energy was estimated to be an astonishing 220 peta- electronvolts (PeV)"

🧵 A nice circumhorizontal arc (informally known as a fire rainbow, which is a misnomer) over West Virginia captured by Christa Harbig! It is an optical phenomenon belonging to the family of ice halos, so it is neither fire nor a rainbow. ➡️ apod.nasa.gov/apod/ap21083... 🔭 🧪 #science 1/3

There's nothing I don't love about WOMBATS, from their curmudgeonly mannerisms to their armored, bony butts (that protect them from predators when they're head-first in a burrow). But we should talk about their cubic poop & how it gets that way. CW: animal poo in next post

Two nights of 3:45am alarms, blazing full moon lighting the sky like daytime and washing out the light of everything else, comet included. Then two days of post-processing battles, as comet processing is maddeningly tricky. But I finally pulled it off: here is C/2025 A6 Lemmon. 🔭 #Astrophotography

Comet C/2025 A6 (Lemmon) as seen this morning. I kind of feel the black and white version brings out more detail in its tail. #comet 🔭

I’ve followed this film maker/Youtube creator for a long time. Interesting perspective. #Sora youtu.be/I1dW-nZqhew?...

In continued celebration of a decade of GW detections, some of the @vanderbilt.edu astrophysicists made this fun explainer video. We had a great time making this; just the right amount of cheesy delivery. My students have already gotten a kick out of it. www.youtube.com/watch?v=bmkt...

Oh dang. This is an excellent analogy.

An elegant waltz occurs just off the East Coast of the US, as Hurricanes Humberto and Imelda put on a captivating performance.

#Humberto and #Imelda are so close to each other that their circulating winds cancel each other out in a calm “col” area in between them. 🇧🇲 Bermuda needs to be on alert however as Imelda will likely cause flash flooding and damaging waves from Wednesday into Thursday.

Putting the Secret Service's nonsense framing aside, it's a pretty cool discovery. Those black boxes are SIM gateways which you plug sim cards into and they act like virtual cell phones. They then route the access over the internet so people can use the sim cards from anywhere in the world.🧵 1/3

Wife: That cast iron skillet you left by the sink left a rust stain on the white counter top. Me: Hmm...we need a chelator. Wife: a key-what? Me: opens fridge and grabs lemon juice. "The juice contains citric acid that will...." Wife: Just do your thing. 😁 #Chemsky

Sigh, first pic for me from that feed. 🙁

🤣

100% myself. 😊

As a long time follower of this experiment, the engineering and physics involved has always astounded and delighted me. Great thread. #LIGO #Astrophysics #Astronomy

As we're all taught, you can (usually) only directly date the age of a rock if it cooled from lava. But here, scientists have dated dinosaur eggs, using uranium-lead ratios in the calcite. Hugely exciting, maybe groundbreaking. My take @science.org www.science.org/content/arti...

Tiny, colorful baby scallops — a total cuteness overload in one dish! You might think, “This person posts the same creature every year!” But honestly, seeing the same life return year after year is something truly wonderful𓂃🫧‪
