The world is indebted to heroes who work alone or in groups to discover, invent, or design
advancements for mankind. Science projects may be years in the making and often take extreme dedication and effort, sometimes
to the detriment of an individual's personal life. The very existence of plant and animal life is very much dependent on the
science community as it works to overcome man's creation of problems dealing with the environment, population, and health.
There have been times when the cultural values of the day may have prevented scientists from working on specific projects. Stem cell research and
the cloning of animals have had limits placed which affected what experiments scientists could actually proceed with. During World War II, Hitler
allowed his scientists to perform horrendous experiments on humans in hopes of perfecting a master race. Countries with low respect for human life
can permit tests and experiments that ignore human values.
Today scientists are fortunate to be able to use computers in tabulating results or in performing tasks that can be performed to closer tolerances with
computerized research equipment. The researchers also use computers to simulate conditions in experiments that would be difficult to perform otherwise.
