Science is

Science is:

1. the study of Nature

From daily observations of natural phenomena, we can try to draw possible logical explanations (hypotheses). Questions that start with What, How, When, Where, and Who often circle around our curious mind.

A good hypothesis is one that can be rigorously tested using scientific methods, in order to derive evidence that either supports or rejects our hypothesis. This is also known as the Falsification Method, when scientists always subject their hypotheses to various empirical testing. An accepted hypothesis is one that stands such rigorous scrutiny. Even if there is a shred of evidence/data/observation that goes against our hypothesis, the whole thing falls apart (the hypothesis is rejected).


Hypotheses that are well accepted will eventually become a new Theory or Law (more commonly applied in Physics and Mathematics). However, this is not a permanent situation, as advances in Science open new opportunities to conduct new, more elaborate, and more accurate experiments.

This means that Science is never static nor dogmatic. Theories and Laws are being updated in light of new evidences and understandings (a Paradigm Shift).



2. predictable, reliable, and repeatable.

We can build upon present Theories and Laws, a working model to predict an outcome of related experiments and even other hypotheses. The outcome must be reliable, in the sense that results concur with the model. Else, again the Theories/Laws will be modified.

Last but not least, the outcome must be repeatable. Science is not any mumbo-jumbo that gives a whole lot of excuses in case the outcome is not as predicted.
