“One aim of the physical sciences has been to give an exact picture of the material of the world. One achievement in physics in the 20th century has been to prove that this aim is unattainable”

-Jacob Bronowski

Natural Sciences often seem to many as completely straightforward, however this is simply not the case. To explain this, we can remind ourselves of the Scientific Method, the way of expanding our knowledge; all the scientific method does is to find a testable theory that passes the test.

However the theory can have some errors in it that even if they produce positive results mean nothing. A greatly simplified way of explaining this is “Liquid metal makes water evaporate.” Firstly many would use heated up metal for this, only the ones using a liquid metal at room temperature such as mercury would be able to disprove of this obviously erroneous theory. As the test different metals they would claim that their theory passes all the tests positively. This makes one wonder about actual theories that are being tested. Some tested theories need external knowledge, such as the fact that heat (over a 100C) makes water evaporate, but what about the theories that enter areas without any previous knowledge? A less exaggerated and real examples are the many physical theories that only work on earth, once we leave the earth to go in places unattainable by humans,  science as a way of knowing becomes much more complex.[This is one reasons why mathematicians dislike the scientific method]. Sometimes, scientists also build up untestable theories also built up on other untestable ones that end up making improbable assumptions such as Quantum Logic, that has managed to show us how little our understanding of the universe is; linking to the claim that science has proven that giving an exact picture of the universe is impossible.

Defining science is another word having subjective definitions. Questions such as: “Is Homeopathy scientific” are answered in different ways by many scientists, who in turn refuse to call the “opposing” camp “scientists”. Some unwanted pseudo scientists such as astrologist sometimes want to fit in as defining what they come up with as ”science”, rejecting the unfavourable association with the term “pseudo science”. But some “sciences” blur the line separating these two “sciences” even more; pills producing placebo effect. Antidepressant pills do show positive results but what is it that makes them work? Their composition which would then place them into ...
