WHAT ARE THEY?

• An invention is a new composition, device, or
  process. An invention may be derived from a
  pre-existing model or idea, or it could be
  independently conceived in which case it may be a
  radical breakthrough. In addition, there is
  cultural invention, which is an innovative set of
  useful social behaviors adopted by people and
  passed on to others.Inventions often extend the
  boundaries of human knowledge or experience. An
  invention that is novel and not obvious to others
  skilled in the same field may be able to obtain
  the legal protection of a patent.

WHY ARE THEY IMPORTANT?DO YOU KNOW OF ANY FAMOUS
INVENTORS?

• The most important Ancient Greek invention was
  the invention of True and not only Applied
  Science around 600 BC with Thales.
• But as more arts were invented, and some were
  directed to the necessities of life, others to
  recreation, the inventors of the latter were
  naturally always regarded as wiser than the
  inventors of the former, because their branches
  of knowledge did not aim at utility. Hence when
  all such inventions were already established, the
  sciences which do not aim at giving pleasure or
  at the necessities of life were discovered, and
  first in the places where men first began to have
  leisure. This is why the mathematical arts were
  founded in Egypt for there the priestly caste
  was allowed to be at leisure. Aristotle

ADHESIVE TAPE

• Richard G. Drew (1899-1980) invented masking tape
  and clear adhesive tape (also called cellophane
  tape or Scotch tape). Drew was an engineer for
  the 3M company (the Minnesota Mining and
  Manufacturing).
• Drew's first tape invention was a masking tape
  made for painters in 1923 (this tape was designed
  to help painters paint a straight border between
  two colours). This early masking tape was a wide
  paper tape with adhesive on only the edges of the
  tape - not in the middle. Drew made an improved
  tape called Scotch (TM) Brand Cellulose Tape in
  1930. This tape was a clear, all-purpose adhesive
  tape that was soon adopted worldwide. The first
  tape dispenser with a built-in cutting edge was
  invented in 1932 by John A. Borden, another 3M
  employee.
