application, but an application can
exist before research is done to explain
how it works.

Aspirin
Long before researchers figured out how
aspirin works, people used it to relieve pain,
and doctors prescribed it for patients who were
at risk for a heart attack.
In 1971, it was discovered that aspirin can
block the production of a group of chemicals
that cause pain and lead to the formation of
blood clots. This is an example of pure
research.
