The Aim of a Scientist: To work with the past along with the
present to develop new theories, to improve
the scientific explanation of the world aroundus.
Taking into account new facts found with
current technology they form a general law.

Natural sciences
Science is built of facts the way a house is builtof bricks: but an accumulation of facts is no morescience than a pile of bricks is a house?
- Poincar
Do the natural sciences make any assumptionsthat are improvable by science? e.g Thateverything that happens is caused, that all causes
are physical?If so, what does this imply about natural sciencesas an area of knowledge?

The Scientific method
Science is best defined as a careful,
disciplined, logical search for knowledge about
any and all aspects of the universe, obtained
by examination of the best available evidence
and always subject to correction and
improvement upon discovery of better
evidence. What's left is magic - and magicdoesn't work. - James Randi

Changes in Science
The world was once though to be Flat. It was
accepted as a law, a general truth. We now
know this to be false.
Pluto has now become and Ex-planet, still
truthfully unsure about its status.

due to the development of new techniques
for observing investigations, including newtechnologies,
through new ways of thinking,
or framing the questions asked.

Why do we accept scientific theories
as Law?The reason why we dont believe in fairies but in electrons is because Fairies are
much more free. A fairy does what it decides to do. We havent been able to find
any useful rules for predicting how a fairy will behave under particular
circumstances, or even for telling when a fairy has been involved in a particular
observation. - Benjamin Kuipers
