Science is humanity’s collective effort to explain and understand phenomena in the natural world in a coherent, consistent and rational mode.
To accomplish this it meticulously observes,, analyzes, and studies specific aspects of the phenomenal world, using a variety of tools and techniques.
These tools include a plethora of carefully designed instruments ranging from the telescope and the microscope to the thermometer and the barometer and countless more in between. Science also uses measurements and mathematics whenever possible, adopting internationally agreed upon standards and units for the measurements.
Science’s tools also include carefully and precisely defined concepts, and the hypothetico-deductive method of formulating theories which consists in proposing hitherto unknown and unobserved aspects of the world, deducing therefrom consequences that might correspond to what is actually observed, sometimes leading to predictions of altogether new phenomena.
Every proposition (hypothesis, theory, idea, discovery) in Science is subject to thorough critical analysis by a body of experts (peer review). In this context, the term experts refers to people who have devoted many years to a specific field of study, and to which they have themselves made significant contributions. The experts are the only authorities that Science recognizes, and even they are not regarded as infallible.
Working in this framework Modern Science has made more discoveries and brought to human thinking deeper and more fruitful understanding than what had been achieved by humanity in the previous many centuries.
With all that, Science never considers its word as final, for it recognizes that its understanding at any period of time is a function of the currently available information.
It is ironic that with all that, billions of people all over the world hardly know what Science really is, and millions even overtly reject the findings of science.
