If you care to research this thread, WOT, you'll find that we have already covered the Coriolis effect, e.g., on Page 288.

"The Coriolis effect due to the Earth's rotation bends the direction of surface ocean currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere."
Actually, I don't care to waste time searching through 541 pages of Lounge Room nonsense, thanks.
I rarely even, very rarely.... click on any post of such lengths, because I know they contains endless babbling and debating that bores the death out of me.
Besides, this being the Lounge area, my comment was of a sarcastic nature.

On this thread, we try to combine intelligence with wit, however some may regard it as a work in progress! 😉

We are all micro-organisms in the universe of things.
Picture a huge, emense fish aquarium as being the universe, and we're all fish floating around in it.

I was curious what the Latin word, perhaps a particple, "Emense" meant... perhaps it would have been better to employ "Immense"?

It gets worse:

All fine and good there, Stevie boy.

However, do me some research om WHY the common toilet flush makes the swirling water go down in a certain direction.
The aliens from Planet Zackbar are asking for this queer phenomenon.

Surely the word OM is part of Buddhist Chant? Om, mani, padme, om... an' all that.

With two spelling mistakes so far, surely you must admit a certain linguistic uncertainty? Therefore a doubtful source?

More certainly, though we admit the Coriolis Effect, it might be greater in one hemisphere than another.

Reason I say this is our Universe is, AFAIK, left-handed:

Don't take my autistic criticism too hard. But you are dealing with "Third Kind" here. We are mainly visual, but at the highest level can do words too. A matter of training.

The search for hypothetical right-handed (sterile) neutrinos has been underway for some time, but it is possible that cohesive evidence for their existence may never be found.

Meanwhile, back in the practical world, neutrino astronomy is an emerging field in astroparticle physics.

Neutrinos travel across the Universe without absorption or deflection by magnetic fields, making them ideal astronomical messengers.

Because their interactions with matter are extremely feeble, sophisticated detection methods are required, such as those at the IceCube neutrino observatory.

Could it be that we overlook the Vera C. Rubin Observatory?

I haven't overlooked the Vera Rubin observatory. I mentioned it some time back as having the potential to improve the +/- 7% uncertainty that Dark Matter exists.

I've been reading about Loenhard Euler, whose work in mathematics is so vast that it is impossible to summarise here.

Pertinent to the thread, Euler wrote books on the calculation of planetary orbits and the motion of the Moon.

We owe to him the notation f(x) for a function, e for the base of natural logs, i for the square root of -1, π for pi, ∑ for summation and many others.

We live in an age of scientific wonders, which Gauss and Euler would be busy doing their calculations on, if they were still around.

This is a Kepleresque graph of the masses of various Hadrons and Mesons:

Very central to String Theory as an explanation of Regge Trajectories. Guess who firmed up the theory?

https://en.wikipedia.org/wiki/Beta_function#Applications

Euler! The Euler Beta function.

I often apply the Euler Zeta function to the problem of annoyingly bright street lighting, when about my astronomical observations.

https://en.wikipedia.org/wiki/Proof_of_the_Euler_product_formula_for_the_Riemann_zeta_function

Unfortunately our local council lacks mathematicians to correctly direct our street lights down, and an understanding of colour temperature to control glare!

They are hopeless on the subject of dark skies! Sorry to rant. 🙄

Your post is replete with Wiki references, Steve, but difficient when it comes to explanations!

My searches reveal that Euler considered the Zeta function when calculating the sum from n=1 to infinity of 1 divided by n squared.

He obtained the answer pi squared divided by 6.

I await your explanation of how this relates to "the problem of annoyingly bright street lighting".

You're not suggesting that the the Euler solution is related to the fact that the intensity of light is inversely proportional to the square of the distance from the source are you?

Euler Zeta (2) sums to Pi^2 /6 = 1.644493...

1 + 1/4 + 1/9 + 1/16 ....

What this means in one physical interpretation is with a row of street lights, it is the nearest 3 or 4 that do most of the useful lighting. The rest are just useless glare.

Lamps should thus have shielded downward pointing enclosures. Colour temperature matters too, since the blue end merely destroys your night vision and yellowish is much gentler.

Terrible light pollution here even from the beach in Portsmouth! And most of it just careless design on the Isle of Wight. Jupiter and Saturn conjunction at a recent Christmas.

Modern dazzling bluish LED car headlights are a thoroughly bad idea too, for the same reason.

I care about this stuff.

We are denying about 99% of the population the chance to see the wonder of the night sky. It's actually quite an easy and cheap problem to solve.
