Bernoulli & Special Relativity

Post

From Bernoulli, we know that static pressure is lowest where dynamic pressure is highest. For example, an airfoil uses camber to increase the dynamic pressure (velocity) of air flow on the low-pressure side to reduce static pressure.

From special relativity, we know that time is slowest where speed is highest - I think. That's how we can observe time dilation between two object traveling at different speeds.

Graphically, they both essentially look like this...

...where the red line represents static pressure/time as a result of higher dynamic pressure/faster relative speed, and the blue lines depict the reason behind the difference.

Is there any connection here? And if so, what is it?

(I promise I'm not high. Yet.)

Similarity is in human propensity for pattern recognition..

Scale is the difference..

See vortex - from sink drainage to hurricane to spiral galaxy..

Speed/time as 4th dimension - in scalar terms too, see 'compression lift' - for high speed flight..

( & FYI, back in the `60s, LSD 25 was used - as a creative prompt in various research labs)..

An issue for me is that I sometimes recognize patterns that don't exist, and it can happen with or without psychotropic enhancement. (Though, it always tends to be more fun with it.)

But, on some basic level, are we just talking about conservation of energy and/or momentum in both cases?

Einstein (E=MC2), Newton (inertia), both & all, 'standing on the shoulders of giants'..

Relativity is present in our daily lives, it's just too small to have any perception of it.

Remember that you're comparing against speed of light squared. This basically means that to have any measurable effect you need to be close to the speed of light. Even if the speed is greater than the speed of sound, effects would still be really smal.
