Question for #Mathstodon
When you *draw* a graph (or a graph-like thing) on a computer, either for your own thinking, or for a paper/ formal communication, what do you use?
I am not a #GraphTheory person, so I'm sure I'm missing some - please let me know in the comments.
Boosts are welcome. -

#Mathstodon, can can we figure out the #physics behind this?
At Alnwick Gardens, the water feature #wateglass shows some mysterious behaviour. The water falls from a circular basin, forming a vertical sheet that oscillates towards the bottom. This flutter is surprisingly aggressive and persistent. It disappears when the water flow is disturbed at the top, but when the disturbance is removed the oscillations quickly grow again.
The plaque attributes the phenomenon to pressure differences between the sides of the sheet of water. While I think it's plausible that the oscillation is indeed an aerodynamic effect, this is not a satisfactory answer without an explanation of why the pressure difference occurs.
It may be relevant that the sheet is curved, because the flutter seems much weaker near the edges of the installation. Could the surface tension be pulling the sheet inward, somehow getting into a positive feedback loop with aerodynamic forces? Your guess is as good as mine...

CW: question about math notation
This question doesn't lend itself well to plain text, so I LaTeX'd and screenshotted it. I'll do my best with the alt text.
#math #maths #mathstodon #AskFediEdit: It turns out that Friendica has a MathJax addon. Who knew?
Also, it seems like there are a number of options. The one I like best is:
$$\sum_{\begin{matrix}1 \le n \le m\\n \ne a\end{matrix}} f(n)$$Edit 2: It looks like this doesn't render properly when federated to a server without MathJax support. I suppose I should've seen that coming.
