Guys, there are a lot of really amazing things in the world! And there are also a lot of people out there exploring those amazing things and learning about them! Sometimes when they learn something new, they talk about it, and share it with laypeople so that they can also be excited and amazed.
I fucking love science.
I bet you do, too.
HEY KIDS, YOU LIKE DINOSAURS?
Well PALEONTOLOGY is a science, for sure! Paleontology is the study of goddamn extinct animals and shit using their fossils. If you're studying the dodo, you're probably not a paleontologist, though, because it only counts if your fossils are pre-Holocene. That means before people. Among other things. Look, if you're a people, paleontologists don't give a fuck about you.
They're too busy discovering the biggest dinosaur ever. His name is Dreadnaughtus and, given that he weighed more than seven T-Rexes, this guy would ruin your day if you pissed him off.
Paleo means "old as balls" in Greek, and if you're not into old as balls animals, you're not a paleontologist. You might be a paleobotanist, like Ellie Sattler, or a paleoecologist, or a paleoclimatologist even! You can be paleo-a lot of stuff.
"Dinosaurs are boring, they move too quickly. I want a science that talks about time on an even larger scale."
Like.. the GEOLOGIC time scale? We can work with that. Geology is the study of the Earth, its components, and what makes them change. Also, how they change. Geologists can be found doing all sorts of really amazing stuff, so if you think geology is dumb then I counter with NO YOU'RE DUMB. Look at all these sciences that fall under the mantle (IT'S A PUN) of geology:
Volcanology is the study of volcanoes, which are portals to hell, probably, or kind of like giant zits on the Earth's face. Volcanoes form where plates of the earth's crust are either being pulled apart (divergent tectonic plates) or pushed together (convergent tectonic plates). They can also form at weak spots in the earth's crust, or when diapirs of magma push up from under the crust. You can think of a diapir as one liquidy-smushy-moving material is able to force its way through a brittle-y, breaky other material. Protip: magma is liquid rock found underground; once it comes up and out it stops being magma and starts being lava.
But wait! The definition above is a bit misleading because you can also study solid "earth" that isn't actually on Earth. Like, say, the geology of other bodies in space. You into that? You should be, because it's rad as fuck. The people who realized this early on and studied it extensively are called exogeologists, or planetary geologists, or just Really Cool Dudes.
There's also Mineralogy, which is the study of the crystal structure, makeup, and general properties (like refraction) of minerals. If you like maths and things that are beautiful and also chemistry and also SECRET SURPRISES, mineralogy is a thing to consider studying. People think it's boring but people are wrong.
That is a picture of a mineral called chalcanthite, which forms in dry climates on late-oxidization-stage copper deposits. SUPER GORGEOUS, right? here's the SECRET SURPRISE: It's water soluble, and if you lick it, it MIGHT KILL YOU. That's right, it's poisonous!
This silky hair stuff is a beautiful mineral, too! It's called tremolite, and in its silky fibrous form, it is recognized as a kind of asbestos. Just a reminder: asbestos causes oodles of cancer and a chronic inflammatory condition called asbestosis, because you get it from, y'know, asbestos.
Okay I guess I gotta stop talking about rocks. There are other natural sciences, though. Wicked cool sciences like BIOLOGY, which is the study of living things! Just like the other types we've discussed, there are a million subdisciplines in biology! Molecular biology, ecology, neuroscience...
Then there's CHEMISTRY, PHYSICS, ASTRONOMY, SOCIOLOGY... BIOMEDICAL ENGINEERING...
Look, okay there's a lot of scientific ground to cover and that's not really why I wanted to make this thread. I wanted to make this because I bet there are other people out there who do a lot of science reading in their day-to-day, and often see things and think, "THAT'S AMAZING!" Well, I want you to share with me your AMAZING SCIENCE THINGS that you find! We can talk about how totally incredible all the stuff around us is. (It's pretty incredible.)
I fucking love science.
I bet you do, too.

I wish there was a proper print version of this, there's one high-resolution one but it's of pretty low quality once you actually zoom in.
Photographer Aaron Ansarov has been taking pictures of Portuguese Man-of-Wars for a while now, and they're gorgeous.
These are super fascinating animals, and the photographs are out of this world beautiful. There are tons more if you click the link, and some of them moooooove.

jellyfish are fucking terrifying.
Somebody has to have made an actual calendar out of that, right?

What.
sounds like witch-talk to me.
and it leaves nothing to the ship of the imagination

This is all I want in the world.
Well, this and a nice MLT.

Need some stuff designed or printed? I can help with that.
my sister is an anthropologist, and I approve of this joke.
A single tear fell on my anthro degree from the University of South Carolina as I typed this
So maybe if I'm feeling ambitious later I'll write something up but it's hard to make fluid dynamics anything other than booooooring
I'd be interested in reading about it, even though I have no idea what you're talking about.
WHAT
Navier-Stokes whaaaaat
And I bet I will find it pretty interesting!
I nearly waxed rhapsodic about rocks for another page worth of OP, it's not that much of a stretch.

Listen, I start talking about viscosity and vortices and vapor pressure and then their eyes start to wander and they play with their phones
I should really just show people the video of the pistol shrimp and call it good
"Now picture an army of these attacking this propeller..."
i mean, you can't really go wrong with Mantis Shrimp, and you definitely understand the basics of cavitation afterwards

But not with shrimp
Cavitation is some awesome stuff.
You see, the faster a fluid moves, the lower the pressure becomes. You can actually get a fluid moving fast enough that it fucking vaporizes!
It's not like it disappears forever, though, so when it slows down, like from hitting a propeller, that little vaporized bubble will collapse. BAM! LIKE AN EXPLOSION but backwards! Here's the cool part: when that bubble collapses, it creates a shockwave of tens of thousands of PSI which can take a chunk of metal out of the propeller with it.
I think I understand this concept, but can you explain a likely scenario in which this would happen? Can it happen when any vapor hits a a propeller or only when vapor formed due to cavitation hits a propeller?
wooo
informative, but boring

Science
This will be here until I receive an apology or Weedlordvegeta get any consequences for being a bully
Well, see, pumps have this thing called "net positive suction head required(NPSHr)" based on the geometry of the impeller. It also has "net positive suction head available (NPSHa)"
Now, pressure is measured in feet, as in how high a pump can push a column of water or whatever it's pumping. So at sea level, where a pump inlet is exactly at the level of the fluid it's pumping, you have roughly 34 feet of NPSHa. So if your pump requires 25 feet of NPSHr, the closer that pump comes to 9 feet above the surface of the liquid the more likely it is to cavitate. This happens often in scenarios where a fluid level changes a lot and the pump for whatever reason cannot be placed at the bottom of the fluid reservoir. Like, say, a pump placed at the edge of a pond.
Then we decided, fuck it. Let's make it super stiff.
