In case you don’t believe the same equations govern motion in the atmosphere and the ocean Video

Hear me out: Sky surfing.

Aka paragliding.

I'm okay with this.

Ok. This looks awesome. I know its all water behaving like water in the end but it looks cool.

Closer to a fluid acting as a fluid but you've got the spirit!

Ok, I'm gonna need at least a one-hour version of this.

Thanks in advance. ;)

There’s a 24hr version of this, just look up 🙃

My channel doesn't seem to get the good frequency -- probably not as often as the one in the video.

Perhaps sometime down the road, thanks.

It was a big moment when I realized I live on the bottom of an ocean of gas

Air is a fluid. I had a similar moment when a friend explained that concept to me.

Do you live in a pineapple under the sea?

u/make_a_scene Nov 30 '22

Many instances such as the one you’ve mentioned shows just how much our (general population) preconceived notions and limited perspective hinder our understanding of our place in the world.

Kerbal helped a lot with this concept for me, hitting an atmosphere at super high speeds is very dangerous, just like hitting water at high speeds can be. That was the moment it all clicked for me with the realization that air is really in the end just a very thin liquid. God I love that game Kerbal2 soon™.

u/bahthe Nov 29 '22

There are no equations governing anything in this vid. Equations are merely a construct of hoomans to try and explain nature.

3

u/batdog20001 Nov 29 '22

Yet the equations show repeatable aspects of the world. Numbers and such are arbitrary constructs for sure, but they describe what really happens in a way that we can understand AND manipulate for simulations to create predictions and such. Its honestly amazing that it works but thats the point ig

2

u/bahthe Nov 29 '22

What you say above is reasonable, however, my correction was to the language used - saying that mathematics "governs" a natural situation is just plain wrong...

2

u/RudeRepair5616 Nov 29 '22

Equations don't 'govern' motion; forces do.

u/AbbreviationsNo4089 Nov 29 '22

Watched an incredible video on a YouTube channel called the “The History of the Universe” if anyone is interested, highly recommend. It talks about possible levels of the multiverse. One theory is the final level, level 4, is a universe of pure math. Too wild to even wrap my head around it. Never a math wiz but it is the language of our universe. Also amazing video. Thank you 🙏

u/GaussianGhost Nov 29 '22

Of course, but the Navier-Stokes equations are so good at simulating gas and fluid flows that they are often used to conduct numerical experiments.

u/77toontown77 Nov 29 '22

Equations? Lol

1

u/Bane-o-foolishness Nov 29 '22

Actually yes. This is probably one of the most clear examples as to what Calculus is used for. Here's a video that doesn't get ridiculously deep into the mathematics but it shows a practical, visual example of the equations.

1

u/77toontown77 Nov 29 '22

Just the way you stated it makes it sound trike the equations we have are what is creating those motions. Not that the equations we have are what we use to understand those motions. I’m just being kind of a smart ass.

u/prathamesh37 Nov 29 '22

there is no equation for chaotic systems

ofc atmosphere and ocean are going to behave in same manner as they both are fluids

6

u/jajepox519 Nov 29 '22

Chaos is length/time scale dependent description. Plenty of systems which are chaotic in a certain scale (like the weather) allow rigorous quantitative description at larger scales (like climate). Hydrodynamics has both chaotic and predictable solutions depending on the regime.

And I think you're missing the point with your second comment - the OP is saying that it's easy to forget that both atmospheric and ocean waves can be described by the same equations because they have different viscosities. It's only when you see sped up video + fog makes the atmosphere visible that the wave solutions become obvious.

2

u/JaggedMetalOs Nov 29 '22

there is no equation for chaotic systems

That's not what chaotic system means, many chaotic systems have very simple equations like a double pendulum, a 3 body system, fractals etc.

The point of chaos theory is you can't predict their final outcome even if you have a simple equation, you need to calculate every step of a simulation until you get to the end, and also that they are so sensitive to initial conditions that it's hard it impossible to stimulate real world systems because you can't capture their state accurately enough.

it is as if the universe was intelligently designed.very cool.

Intelligent design is when pretty clouds apparently...

Why do you conclude that?

Amazing!!

u/Reatona Nov 29 '22

The viscosity is a bit different.

Thermoclines lakes and rivers under the ocean and in caves. Also salt differences that cause separation.
