1/16

Why do we accept Natural

science theories as Law?


2/16

Ways of knowing common in scientific

culture and within their explanations.

And how this leads us to accept scientific

theories as Law?


3/16

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.


4/16

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?


5/16

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

WHAT IS THE DIFFERENCE?


12/16

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.

Is Science subject to change?

Science knowledge may change:

due to the development of new techniques

for observing investigations, including newtechnologies,

through new ways of thinking,

or framing the questions asked.


16/16

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
