You really only just learned that?

Your third grade teacher would like a word...

I don't think I knew the english word "fluid" in third grade

I was today years old when I learned air was considered a fluid, but by definition, it makes sense.

yea, fluid translates to the norwegian word for liquid, so I thought fluid meant liquid.

Mr Wizard told me bout that one in about 1984 https://www.youtube.com/watch?v=u0AH_GNviyw

TIL there is more water than air.

Gases and Liquids are fluids

And then you realize that we all live at the bottom of an ocean.

If the Norwegian word for fluid is synonymous with liquid, what is the Norwegian word for non-liquid fluidity? Surely there is a way to express this concept in that language.

gass

don't think we have a word that covers both liquid and gas like fluid does.

Yea, I’ve always assumed air was a gas, I learned what you stated, not what the misleading title implies

The fact that you know nothing about this person or his/her age and are still incredulous that they didn't learn this information at the exact moment you did makes you look far more ignorant.

SpongeBob intensifies

Solids liquids and gases are different than fluids

If the word phlogiston isn't mentioned, I'll scream

Well, yes. Air is a fluid because it flows. That's literally the definition.

I've argued with people my age, 58, that air is a fluid. It's usually when a pump is sucking air and I say "the pump can only move one fluid at a time..." and then they want to argue that air isn't a fluid.

OK, curious: Fluid Dynamics can be broken down to (among others) aerodynamics (gas) and hydrodynamics (liquid), or pneumatics (gas) and hydraulics (liquid). So what do Norwegians call "Fluid Dynamics" and what you you break it down to?

I fell like I'm delving into the American debate/argument that there is a difference between an engine and a motor. In most languages, when you translate "engine" it becomes motor.

I'm also reminded of the "stoner" meme that keeps popping up here: do crabs think fish can fly? Well, it's fluid dynamics. If humans think birds fly, sure crabs think fish fly.

Anything that flows

Yea, plasma is a fluid

Fluid, it's called fluid in Norwegian as well. The word for liquid fluid is 'væske', and if you ask Google Translate what 'væske' is in Norwegian it just returns 'fluid'.

Yeah lol. Ok so now I have a question for you. If a balloon is in the back of a covered trunk, no air influence from the outside, and the truck turns left, which way does the balloon go? It’s tied to a string inside the trunk.

well written and a VERY good point

Liquid? Fluid

Gas? Also fluid

Solid? Believe it or not, fluid

Plasma? You're right, fluid

We have the best matter in the universe because of fluid

Electricity has some fluid properties if we are being honest.

It just then has some not fluid properties also .

You didn’t specify what the balloon is filled with. If it is less dense than air: to the left as the air is pushed to the right pushing the less dense balloon to the left. If the balloon is filled with something denser than air: to the right as it pushes air out of its way.

that's more of a trick question than anything.

Didnt know I was a fish

When a dense mass of air has a less dense mass of air on top of it it can even have waves like the ocean. A lot of what meteorologists do is based on fluid dynamics because weather is the side effects of these high and low pressure zones forming and interacting with each other.

I guess fluid has a fluid definition

Liquids & gasses flow &, therefore, are fluid.

Air is not a liquid as a liquid cannot be compressed. Air however can be.

fluid means "liquid, gas, or plasma" I used to think it just meant liquid, but it also includes gas and plasma.

How is the title misleading? It's just someone not understanding scientific terminologies

You need new friends

They are capable of posting to reddit so not a toddler.

Goo goo gaga

What? Like highly dense air can carry liquid. Does that make it a liquid?
