I can't seem to get the Latex to work in Markdown. Is is that I can't see it with my browser? How do I fix this? (I use Chrome or Brave)

example: \ (x+y=z\ )

leaves have surfaces that have a degree of wetability, water will either stick to a surface or it will flow off depending on the ecological needs of the leaf. Nonwetable leaves have complex surfaces that modify the surface pressure of water so it forms droplets and flows off. The reasoning and mathematics of this is explained in this video:

My question: The complex surface looks fractal, is there a scaling law going on here?

Very interesting result for high D nonlinearity

#horrorvacui

Does Nature abhor a vacuum? Called _horror vacui_ in Latin, the idea originally came from Aristotle. If you put a cylinder with a plunger in water and pull back the plunger, the cylinder will fill with water. According to Aristotle, the water follows the plunger because it is afraid of creating a vacuum. The Italian mathematician, Evangelista Torricelli 1606 - 1647 showed this is not true with the following experiment. Take a glass and put it underwater in a basin until it fills up. Turn the glass over and pull it up out of the water's surface so that the bottom of the glass is just below the surface of the basin water. There will be an empty space at the top of the glass. Called at the time, "Torricelli's Emptiness" it is a real vacuum. The reason for this emptiness is pressure, formalized around the same time by Blaise Pascal. So Nature does not abhor a vacuum, Nature creates a vacuum. So why do we still say this? Is it more correct to say that human nature abhors a vacuum?

#whatisachair

Starting the book: The Social Logic of Space by Bill Hillier and Julienne Hanson. Written in 1984, it has a few comments that are dated and some that have been proven wrong but a couple important statements.

“… The structured information on which the system runs is not carried in the description mechanism but in reality itself in the spatio-temporal world. The programme does not generate reality. Reality generates the programme, one whose description is retrievable, leading to the self-reproduction of the system under generally stable conditions. Thus in effect reality is it’s own programme. The abstract description is built into the material organization of reality, which as a result has some degree of intelligibility.”

“… Every society invests a certain proportion of its material resources not in the biological perpetuation of individuals, but in the reproduction of the global society by means of special biologically irrelevant behaviors which are aimed purely at the enactment of descriptions of the society as a whole...”

Hillier, Bill, and Julienne Hanson. The Social Logic of Space. Cambridge University Press, 1984. https://doi.org/10.1017/CBO9780511597237.

I don't agree that these behaviors are "biologically irrelevant" and the notion of how humans perceive space has been turned on its head since he wrote this but I would call this book an early classic in using complex systems to understand human culture.
