Scientific Theory - Examples of Scientific Theories

Examples of Scientific Theories

Note that many fields of inquiry do not have specific named theories, e.g. genetics and developmental biology. Scientific knowledge outside a named theory can still have a high level of certainty, depending on the amount of evidence supporting it. Also note that since theories draw evidence from many different fields, the categorization is not absolute.

  • Biology: cell theory, theory of evolution, germ theory
  • Chemistry: collision theory, kinetic theory of gases, Lewis theory, molecular theory, molecular orbital theory, transition state theory, valence bond theory
  • Physics: atomic theory, Big Bang theory, Dynamo theory, M-theory, perturbation theory, theory of relativity (successor to classical mechanics), quantum field theory
  • Other: climate change theory (from climatology), plate tectonics theory (from geology)

Famous quotes containing the words examples of, examples, scientific and/or theories:

    There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.
    Bernard Mandeville (1670–1733)

    No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.
    André Breton (1896–1966)

    The scientific imagination always restrains itself within the limits of probability.
    Thomas Henry Huxley (1825–95)

    The wise man regulates his conduct by the theories both of religion and science. But he regards these theories not as statements of ultimate fact but as art-forms.
    —J.B.S. (John Burdon Sanderson)
