the signal traveling at 99.7% the speed of light through a hollow-core
photonic crystal fiber.

"Semantics is the technical term used to refer to the
study of meaning, and since meaning is a part of
language, semantics is a part of linguistics.“
Semantic Web is not about links.
Semantic Web describes the relationships between
things (like A is a part of B and Y is a member of Z)
and the properties of things (like size, weight, age,
and price).

Section 7
Section 8
Design must be kept simple and
unnecessary complexity should be
removed.
Simplicity is the ultimate sophistication
Allow new approaches to replace
established ones, reducing unnecessary
complexity and increasing efficiency and
quality
simplicity is achieved by refinement/
evolution
