How certain can we be in the natural sciences?

Extracts from this document...


´╗┐Ashley Kabugo How certain can we be in the Natural Sciences? We use science everyday to explain certain things about the world that surrounds us. These experiments however depend on us as humans as we are the ones that must observe and gather the results from our own observations. The collection of results does depend on human perception and as humans we are bound to make mistakes, or interpret the results in an incorrect way. So if this is the case it is hard to say we can really trust the natural sciences. To begin with, most of our scientific knowledge in the past was based on theory. People used to believe that earth was flat, or that the sun revolved around the earth. ...read more.


To get results, we depend on our senses. Even if we do record the right things and the right results, we can?t be sure that what our senses tell us are accurate. You may need to use a variety of senses to determine something, but your senses also depend on our perception. For example if you were conducting an experiment whereby you had to time something, your reaction time is going to be slower. There is little chance that you will start the timer at the exact time that you need. The reaction time would affect the accuracy of the experiment, so how can we be certain of it? While conducting such experiments we mostly depend on our sight. While our eyes are accurate for day to day things such as seeing where we are going, what we are doing and so on, we do not have microscopic vision. ...read more.


The earth really is round, there are pictures that can prove it. So this is a reason why we trust the natural sciences. Also, it is the only way we have that can really explain the way the earth is. Sciences have helped as discover so much as human beings, and with this discovery come the ability to adapt and grow in order to survive. Life has been greatly improved by science, even lengthened as scientist find cures for diseases. This is also evidence of how on more than one occasion theories were proven right. In conclusion, while there are several things that may still be based on theory that we cannot prove entirely, sciences have helped us in so many ways and everything did start out as a theory, so it really shows how far we have come. I think we can trust natural sciences, not for everything, but most of the time. ...read more.

    The individual behavior is unique to our experiences and personality - not all humans act the same way when put under the same circumstances. It is therefore not possible to generalize a theory that applies to all individuals, as it is in the case for the natural sciences where the theory could be applied to different occurring natural phenomenon.

    Popper also believed and questioned scientist's method of testing, which can as he described be made to suit one's hypothesis. 'Good tests kill flawed theories; we remain alive to guess again'. In other words, if a test has not been correctly and fairly executed it will easily be disproved by another more controlled test.

    How can conviction be proven? One reason of that is conviction is generated by human mind, and perspectives of the believer can be constantly changing since knowers are constantly being exposed to information. In order for knowledge to be justified, it must have the quality and ability to be repeated by others.

    This finding is in disagreement with one of the most fundamental laws of physics, Einstein?s theory of special relativity. Ereditato explains that they ?tried to find all possible explanations for this,? and everything lined up. He goes on to say that they ?wanted to find a mistake ? trivial mistakes, more complicated mistakes or nasty effects,? but they did not.

    As humans study about the Natural Sciences, there are numerous limitations to their studies, which they eventually sum up as one major fact. For instance, the findings done by humans are limited by their senses in a way that if a particular thing is being measured, one?s sense of sight might interfere with the judgment of the issue.

    this discussion points to the question - What is evidence? Can we call anything that justifies our claim evidence? By looking at the sky I can claim that it is going to rain. But does this amount to evidence. No. Justification only shows the way you arrived at your claim.

    Results should produce evidence that can be repeated. The test to see if distilled water boils at 100° at sea level should be able to be repeated numerous times and produce the desired results. This theory that ‘Distilled water boils at 100 degrees Celsius’ can be proved factually correct irrespective of location of test, nationality of scientist, brand of measuring instrument etc.
