There's a high probability that they don't know anything about anything, maybe less, and a dead certainty that they think they know more than you do about everything.
Very entertaining sometimes.

When you stir a liquid in a cup or pitcher using a spoon or stir stick creating a vortex, does the liquid move up and down, transferring the liquid at the top and bottom to circulate inn a circuitous route? I’m guessing yes,… And if it moves up and down the vortex, does it move up or down the center and back down or up outside of the vessel? I have not found the answer on my own yet.
Take a pitcher of water or some other vessel that's tall and narrow, get a vortex going (maybe with a stick blender if you have one) and add a drop or two of food coloring.
I would think there would be a difference between using a spoon and using a stick, and also depending on whether the stick was like a stirring rod or had some paddle-like dimension. So, no definitive answer given the stated parameters.
"Surface elevation in rotating flow Consider a vertical, axisymmetric vortex in homogeneous fluid with a free surface, e.g., a stirred mug of coffee. Let the height of the free surface be η(r)
. With no vertical motion, the fluid is in hydrostatic equilibrium, i.e., the pressure at each point is the weight of the fluid above it: With no vertical motion, the fluid is in hydrostatic equilibrium, i.e., the pressure at each point is the weight of the fluid above it:
p(r,z)=∫η(r)zρ0gdz=ρ0g(η−z).
Substitution into Equation 7.2.12
gives
η=η0+θ˙22gr2,(7.2.13)
where η0
is the surface elevation at r=0
. The surface is therefore a paraboloid of revolution.5
Suppose we stir a cup of coffee at a rate of two revolutions per second, so that θ˙=4πs−1
. If the radius of the cup is 4 cm and g
= 9.81 ms−2, then the elevation difference should be about 1.3 cm."
Why is it that when someone is taking a picture of other people in normal circumstances, the subject will smile and project a normal demeanor? But if the subjects (even if it's a selfie) think/know the photo is going to be posted to social media they open their eyes wide and their mouths wider in some exaggerated look of surprise and excitement. It's just weird.

The ultimate TMI!

It was a good morning, thanks for asking, Peter.

Reading the ingredients on peanut butter labels, they always use rapeseed or some other oil in it. Why can't they just use peanut oil?

I’m sure you could to a point. You can definitely taste it in milk when they’ve been able to eat a lot of wild onions and stuff.
