Happy Pollinator week to the Baltic Isopod, the first underwater pollinator discovered by science! Lab studies imply that their activities help pollinate seagrass and macroalgea. Is there anything isopods can't do?

I’m not a girl or a boy I’m saying I’m an insect who dreamt he was a man and loved it. But now the dream is over and the insect is awake. yeah any pronouns is fine

Still not over how that fucking submarine was not only made of carbon fiber, which is commonly used for aircraft because it's very light etc, but as you will quickly find out Planes Don't Experience The Same Kind Of Pressure As Submarines. Not only that. But they also used shit carbon fiber. They used boeing's spoilt leftovers. That's insane. I have a little bit of airplane autism do the rest of you understand how insane that is

The thing is that it doesn't even make sense at the very first glance as a material to make a submarine out of. The main draw of carbon fiber is how lightweight it is. Yknow if you're trying to fly. This isn't really, like... correct me if I'm wrong but doesn't that not really matter on a submarine. Aren't there other ways you control buoyancy. Am I losing my mind

The words "expired carbon fiber submarine" are just like swirling around in my head right now. Expired carbon fiber submarine. The expired carbon fiber submarine imploded. To the surprise of... about five people, I guess

Another thing about carbon fiber is that it doesn't bend. Once it's been through enough stress, or experienced enough repeated stress (I.e. pressure changes in flying and landing, or. Submerging and coming back up. If you're making a submarine out of it for some fucking reason), where other materials might noticeably warp, carbon fiber will just break. It just snaps. Estimating when this will happen is a Whole Thing. They take it very seriously in aerospace engineering. It turns out rich people don't though

One of the few ways an airplane actually *is* very similar to a submarine is that if the hull cracks you will die very quickly

This is why you don't use expired carbon fiber

I know I've been over this but man HRT is good stuff. I wanna shake the hand of whoever invented it. It's a crime that I don't know who that is actually. They're more important than Einstein

id also been really curious about the history of hrt so i had some tabs open:

The first hrt treatments were mostly estrogen extracted during pregnancies to be used for menopause symptoms, but the first usage of those medicines for trans women is credited to the world's first Trans Clinic, opened in pre-WW2 Germany by Magnus Hirschfield, a gay jewish man.

Oh he looks delightful

Thank you grandpa

The comparasion to Einstein was actually made at the time too! He was commonly refered to as “the Einstein of sex”, to which he supposedly once replied that he would rather Einstein be called “the Hirschfeld of physics” lmao

Oh my god

you can only reblog chicken noodle melon today reblog any other day and you fucking die

made it with an hour to spare
