Science, Fact, and Hypothesis

There are many subjects which fall into the category of sciences or the social sciences. Subjects such as physics, chemistry, biology and mathematics come under the category of natural sciences. whereas subjects such as business, psychology and literature fall in the category of social sciences. In Science, there is no limit to what kind of research is done and neither is there a limit to the procedure that is used. Therefore science is divided into branches, different branch looks at different methods and has a different field of interest.

Science is totally a human activity as the objectives of science are to describe, explain, understand, investigate, predict and control, and these are characteristically human goals. Science is considered as supreme because of its reliability, definiteness, precision, objectivity or intersubjectivity, testability, self-correctiveness, comprehensiveness or universality to inform, to predict, to control, and to summarize the data economically.

A theory is brought up based on facts, instead it is selected to give us new objectives. A theory does not come up by automatic induction, nor by generalization, and nor by observation of general regularities, but it comes about by someone’s imagination to a new merging idea.


There are six ingredients that can determine what a fact is:

  1. The Human Organism
  2. The scientific instruments available. The methods and conditions of observation relate to the “fact”. Things do not have a size that is independent of the instruments used to measure it.
  3. Memory: one can only remember something if the sense of what had occurred in the past is still alive in his brain.
  4. The personality, aims, and bias of the individual scientist.
  5. Language: Observer can describe something only by the language that he can speak and every language has its limit. There are some languages in which some things are not given any name.


A fact cannot be determined without knowing the hypothesis. A hypothesis must meet eight conditions in order to be of maximum usefulness in acquiring and organizing knowledge.

  1. A hypothesis cannot be a reasoned statement, so a hypothesis must be falsifiable, because if it is not then there is no point of carrying out the experiment.
  2. The explanatory hypothesis must be true.
  3. The hypothesis must be simple. Simplicity may be in the concepts employed, or in the laws in which they are used.
  4. There must be elegance or beauty in your hypothesis.
  1. The hypothesis must be as general as possible. It must not be a victim of unreasonable restrictions such as; time and place.
  2. The hypothesis must refrain from being statistical or probabilistic as much as possible.
  3. The hypothesis must highlight analogies wherever the situation allows you to.
  4. “The hypothesis should, finally, satisfy certain criteria that can best be described as metaphysical: that there is no infinite regress of explanatory causes; that there is continuity  in the world; that the world be regarded as stable; even that the world be properly anthropomorphic.” (Man is the Measure, pg – 88)

I think facts play an important role in the science as without facts one cannot come up with hypothesis or ideas. For anyone to introduce a hypothesis or a new idea, he or she must have factual knowledge.

In its more restricted contemporary sense, science refers to a system of acquiring knowledge based on scientific method, and to the organized body of knowledge gained through such research. This article focuses on the more restricted use of the word. Science as discussed in this article is sometimes called experimental science to differentiate it from applied science - the application of scientific research to specific human needs - although the two are often interconnected.

Science is a continuing effort to discover and increase human knowledge and understanding through disciplined research. Using controlled methods, scientists collect observable evidence of natural or social phenomena, record measurable data relating to the observations, and analyze this information to construct theoretical explanations of how things work. The methods of scientific research include the generation of hypotheses about how phenomena work, and experimentation that tests these hypotheses under controlled conditions. Scientists are also expected to publish their information so other scientists can do similar experiments to double-check their conclusions. The results of this process enable better understanding of past events, and better ability to predict future events of the same kind as those that have been tested.

Science is a study of the physical Phenomena around us. My opinion is that science (natural sciences) are widely accepted as the superior sciences than the human sciences as the level of precision, experimentation and discovery is rigorous. Apart from that, I believe that in science, its not about what is the other's opinion. Here, more attention is paid upon logical reasoning based onour observations, inference, hypothesis and the complex methodology used in experimentation. Unlike the human science, natural science involves more detail, complexity, accuracy based on experiments conducted in a controlled environment, which in areas of the human sciences is not possible.

  1. ToK: "Science is built of facts, the way a house is built of bricks.."

    When the words are carefully chosen, properly ordered, when their meanings are appropriate, then we have an ordinary sentence and maybe a text. And that is of great importance, because in our daily routine we use language mainly as a tool to express ourselves.

  2. Science is built of facts the way a house is built of bricks: but ...

    However with a house this is unlikely to occur from just one brick falling out. But if the foundation of the house fails, then the whole house will fall. This is similar to what would happen in science if a fact was proved wrong.

  1. United They Stand, Divided They Fall

    On the full understanding that science is not exclusive to natural sciences, for the purposes of this paper, I shall only discuss the formation and purpose of scientific explanations in one particular aspect of natural science, eclipses. According to Hempel's deductive-nomological model, the explanation as to why eclipses occur can

    Though an inquiry was unable to determine the cause of the explosion, the U.S. press conducted a hysterical campaign to blame Spain. The campaign helped win public support for the Spanish-American War in which the U.S. seized control of Puerto Rico, Cuba, Guam and the Philippines, launching itself as a world power"( http://socialistworker.org/2002-2/427/427_07_HistoryOfLies.shtml)

    For example in physics - the law of gravity applies to all objects on earth. In psychology however, results are hardly ever generalized to anything large-scale like in the already recognised natural sciences. According to one of the websites I visited, it states that, "Scientific laws are generalisable but psychological explanations are often restricted to specific times and places."

    wants to prefer to live with the people sharing his ideologies and viewpoints. For example, as per a report from a survey conducted in the U.S., it has been found out that individuals tend to live at places, the names of whose start with their names.

  1. The more falsifiable a theory is, the better it is. Discuss.

    that it is very scientific because we might find a way to disapprove it. The patient would probably doubt on its effectiveness on him even though it?s a symbol of ?scientific?. That?s also why those ?pseudo sciences? get advantage to be popular; the public is in a lack of the understanding of ?a falsifiable theory?.

  2. Defining and Analyzing Mixed Method Johnson and Christensen (2007) describe mixed research as the ...

    Mixed methods designs can provide pragmatic advantages when exploring complex research questions. The qualitative data provide a deep understanding of survey responses, and statistical analysis can provide detailed assessment of pat terns of responses. However, the analytic process of combining qualitative and survey data by quantifying qualitative data can be
