People ask why I still call this website Twitter and why I still call these things Tweets, so here's the "Hank Green Style Guide on Twitter and X." If a billionaire took over my city's government and said "Your City is Now Called X" I would say, "That's silly, my city is called Missoula. I live here and it's called whatever I call it...but I'm happy to call the government "X" because that's the thing you actually took over.

Wild stuff going on in Montana right now. Lemme tell you about it.

One of our senators is a guy named Jon Tester who grew up outside of a town called Big Sandy on land that his grandfather homesteaded in 1912. He has worked his family farm almost his entire life, including the 10 years he’s been in the Senate.

But he started his political career with ten years on the Big Sandy school board.

Can we...just accept that we suck at this?

I want to tell you a story that has made me kinda hopeless about Twitter's ability to affect positive things happening, and it starts with this tweet from Hillary Clinton.

It was (and I understand why) widely mocked. The graph is confusing and bad, especially the part where it flattens out in 2030 (which is when most of the provisions of the Inflation Reduction Act, the largest climate change bill in the history of Earth, expires.)

FYI Charlotte the stingray is not pregnant with shark rays (unfortunately impossible) but she is also not pregnant with clones of herself (also impossible) it's much weirder than that. Charlotte the stingray procreates sexually, which means she isn't set up to create clones. Her egg cells have half of her genome with a random mix of genes from her father and mother.

Usually that would get fertilized with sperm with half of another stingray's genome.

Here's the story of how I kinda bought 10% of an amazing new word game...for charity.

A few months ago, I saw a TikTok about a word game called "Gubbins" that was being produced by a small indie game studio in Australia (@folly_studio) and I messaged the people creating it. Image I got early access to the game and absolutely loved it. It's fun, simple, fast, clever, and most of all ABSOLUTELY DELIGHTFUL. It's just a little piece of art that is part of my daily life now.

Massively under-reported science story because there's so much going on right now but...it turns out that we might have figured out what's causing this very scary spike.

Quick thread, on how WE'VE BEEN ACCIDENTALLY GEOENGINEERING FOR DECADES...but then we stopped: Image So, geoengineering (or climate engineering) is when you intentionally do stuff to change the climate of the Earth. When you accidentally do stuff to change the climate of the Earth, that's just called "The last 100 years."

We've been doing a lot of accidental geoengineering.

It's really a shame that the IceCube neutrino observatory galaxy map was released on the same day as the gravitational wave data because they're both entirely new ways to observe our universe and I feel like it didn't get the press it deserved! Image Like, it's one thing to use pulsars in the Milky Way as a galaxy-sized gravitational wave detector. But it's another thing to actually build a neutrino telescope by lowering thousands of detectors into a square kilometer of perfectly clear, ancient Antarctic ice.

Hey, it's me, the guy who has been early to every social media app somehow. Threads is going to be big. Bigger than Twitter. I'm sorry.

I don't like it either.

Here's why: 1. People are having a ton of fun. The giddiness of cultural creation is real. This was enabled by:

Wanna understand some of the biggest science news of the year (maybe the decade?) better than 99% of people? That new should be coming out tomorrow evening, but we know a bit about it...so here's a thread: For almost all of the history of astronomy we have learned everything we know about the universe by looking at photons. Whether Galileo was looking at the visible light of Jupiter or the JWST was looking at the infra-red of the Orion Nebula (which it did recently...check it out.)

Ok, might delete but…we’re used to thinking about explosions, not implosions. The thing is, they are the same thing, rapid changes in pressure.

An explosion is when a solid or liquid becomes a gas very fast. The gas takes up way more space, and so slams into anything nearby. 🧵 That doesn’t seem that dangerous, but it is. Molecules are molecules, and getting hit by a bunch of fast-moving gas molecules can to just as much damage as being hit by a bunch of fast-moving truck molecules.

(All depends on the speed!!)

I’m going through old papers and I completely forgot that the Toronto Star did a story on 2D Glasses! And here is the online “Number under Number” list I was ever on. The Montana Business and Technology’s 40 under 40.

In 2012, when SciShow had like 60 videos (and we were still very much figuring out what we were) we brought on a video editor named Caitlin Hofmeister. Now, we have over 3,600 videos and Caitlin is the EP of SciShow (basically, the person who runs it.) She has helped define so much about what SciShow is. If you have ever enjoyed a SciShow video there is a near 100% chance that she was involved in its creation.

People are confused by this and I forget that things that are central to my entire life might be unknown to people who are following me on Twitter.

...a thread. In 2007, YouTube had just launched the ability to upload custom thumbnails (before that it was just a frame of the video) and also we knew that, in theory, it would be pretty easy to overwhelm YouTube's clunky recommendation systems.

The more I learn about the history of science the more I feel like every time you heard of some person discovering something it's just...wrong. They didn't discover that thing, they got some piece of data that didn't make sense and refused to stop freaking out about it until they were able to convince some other people that something weird was going on.

Thank you so much to everyone who has shared this, but I woke up this morning feeling so grateful to the people who actually made this happen. So many thoughtful, passionate people are working on this project right now. Too many to name...so today I'll just talk about Nick. I met Nick in a coffee shop in Missoula 1000 years ago. He was a professor at UM teaching film and came off as a very smart, a little bit grumpy guy. I hired him a week later, and we were filming Crash Course biology that month.

In 2010 my brother and I started posting educational videos because we had run out of ideas for our vlog.

Today, with @ASU and @Google, we’re launching gostudyhall.com a path from YouTube to real, transferable college credit, and I want to talk about why (and how). There’s 1.75 trillion dollars of student debt in America held by around 43 million Americans. This seems like a...kinda bad thing, but it is actually worse than it sounds.

People tagging me in this are very sweet but it's a bit tricky to go from Andrew Tate to a guy who cannot do 16 pushups in a row even if he does know lots of science facts.

Anyway, masculinity is complex and fraught and we're bad at understanding it and talking about it. I have two big concerns with masculinity conversations, so I guess I'll say them here on Twitter, where people are always super forgiving and never willfully misinterpret things </s>

I have been given a long and complicated (but very repetitive) task by a six year old and it's cool but...he's a pretty weird boss. Here it is so far...we couldn't find a poster that was just countries ranked by population...he also needs it to be a rainbow.

I'm on Twitter to ask...does anyone know how they figured out atomic weights back in Mendeleev's time? Like, you can get the density of a substance, no problem, and some elements have densities that are proportional to atomic weight, but certainly not all!!

How'd they do that?? OK, with some help...I think I've got it. Gases are great for this because the same number of atoms take up the same amount of space every time.
