sciences in general, what they are and their methods
Occam’s Razor (also called Ockham’s Razor) refers to a principle of parsimony or simplicity in modern science associated with the medieval monk William of Ockham. His principle states: “Entities should not be multiplied unnecessarily.” The word “entities” is ambiguous here: what should be minimized, the total number of entities of any kind or the number of kinds […]
Karl Popper made falsification the key to scientific legitimacy. But as others have pointed out, scientists do not spend much time trying to falsify theories. Instead, they work to confirm and extend theories. Moreover, an observation that goes against a theory doesn’t falsify the whole theory; it creates an anomaly that can be dealt with
The word intension is not as well-known as its homophone intention. The word intension denotes the intrinsic meaning of a word, also called the comprehension or connotation. It contrasts with the extension, which denotes the range of applicability or objects to which the word refers, also known as the denotation. For example, the intension of “boat” is “a
Much discussion continues on the topic of “science and religion” but the concept of religion is vague or arbitrary so it is better to focus on “science and theology.” Christian theology in particular does have some relation to science. Historians have documented the role that Christianity played in the rise of modern science. For example,
When Isaac Newton published his Principia with its laws of motion, he asserted their universal application. Since he had unified motion on the surface of the earth with the motion of the solar system, it was a powerful argument. Nevertheless, to claim universal application excessively extrapolated and interpolated far beyond any data available at the time. But you
Science is knowledge (scientia) that is systematically gained and/or organized. That entails that the terminology of science be systematic, i.e, a nomenclature rather than a hodgepodge of terms. This can make discussions about science hard since people have to learn a body of nomenclature before understanding a science. This applies to all sciences, whether natural sciences,
Scientific theories are in principle subject to underdetermination in that multiple theories could account for the data. In the natural sciences this possibility is strongly resisted. When Darwin proposed his theory in 1859, he could not show that a version of special creation would not account for the data. What he and Huxley did instead was
A recent meta-analysis on the old question of nature vs. nurture (Meta-Analysis of Twin Correlations and Heritability) concluded that overall the variation of human traits and disease is 49% due to genetic factors and 51% due to environmental factors. There is a similar question about nature vs. culture in anthropology and education. Evolutionary theory is
Accuracy refers to closeness of measurements to the true value. Precision refers to variation of measurements to each other. So precision is relative but accuracy is absolute. Accuracy and precision can apply to statements as well as measurements. For example, if I say, “Today is Tuesday. This is the third day of the week.” but
The real scientific method is the inductive method invented by Socrates and elaborated by Aristotle, Bacon, and Whewell. It is different from the hypothetico-deductive method invented by JS Mill in the 19th century which is passed off as the method of modern science. Consider Francis Bacon. He called immature concepts “notions”. Induction starts with notions
