GEOMETRY
Application: Those who follow the geometry materials are invited to design amd if possible build a structure using the principles learned here.
So, we can dream, can't we?

Geometry was born of practial concerns like excavation and construction.
The Famous Pyramids of Egypt required a solid knowledge of certain fundamental principles of measurement, regardless of how well the builders could explain those principles.
Also, if you're Frodo Baggins trying to smuggle the ring out of the Shire, it might be good to know that "the shortest distance between point Shire and point Bree is a straight line."
ESCAPE THE SHIRE
Later, the science was articulated independent of concrete structures, and recognized as a system of knowledge.
Geometry has its own vocabulary which is not in daily use outside of academic or scientific settings.
So, Wildwood recommends repetetive listening to introductory lectures until the vocabulary is no longer strange
English language lectures are widely available online, we have posted some and will soon post more.

EUCLID'S WRITINGS
Archimedes may have been a student of Euclid and was charged with the defense of the ancient city-state of Syracuse.
Since siracusa is now a part of Sicily, you might conclude that he failed.
But in the process of defending the city he invented quite a lot of geometry, calculus and physics.
Incredibly, an Archimedes screw system is still in use in the salt mines of Mozia, Sicily as shown here:
