- Albert Einstein described two different types of scientific theories: "Constructive theories" and "principle theories". Constructive theories are constructive models for phenomena: for example, kinetic theory. Principle theories are empirical generalisations, one such example being Newton's laws of motion.

A scientific theory is a verifiable explanation of natural phenomenon. For example, the theory of gravity explains why an apple always falls to the ground when dropped. A law, on the other hand, is an observation. In simpler terms, a law predicts what happens and a theory explains why.

- Heliocentrism: Copernicus, 1543. One of the greatest insights ever, conceived by some ancient Greeks but established only two millennia later: the Earth revolves around the sun (as do other planets).
- Evolution by natural selection: Charles Darwin, 1859. Darwin showed that the intricate complexity of life and the intricate relationships among life-forms could emerge and survive from natural processes, with no need for a designer or an ark.
- Quantum theory: Max Planck, Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Max Born, Paul Dirac, 1900–1926. Quantum theory ripped the entire fabric of classical physics to shreds, demolished ordinary notions of the nature of reality, screwed up entire philosophies of cause and effect and revealed peculiarities about nature that nobody, no matter how imaginative, could ever have imagined.
- General relativity: Einstein, 1915. General relativity was much more revolutionary than special relativity, because it ditched Newton’s law of gravity in favor of curved spacetime.

There are many scientific theory in different disciplines: 1. Astronomy: theory of stellar nucleosynthesis, theory of stellar evolution 2. Biology: cell theory, theory of evolution, germ theory, dual inheritance theory 3. Chemistry: atomic theory, Bronsted Lowry acid-base theory, kinetic molecular theory of gases, Lewis acid-base theory, molecular ...
In order for an explanation of the natural world to be a theory, it meets certain criteria: 1. A theory is falsifiable. At some point, a theory withstands testing and experimentation using the scientific method. 2. A theory is supported by lots of independent evidence. 3. A theory explains existing experimental results and predicts outcomes of new ...
Usually, a scientific theory is just called a theory. However, a theory in science means something different from the way most people use the word. For example, if frogs rain down from the sky, a person might observe the frogs and say, “I have a theory about why that happened.” While that theory might be an explanation, it is not based on multiple ...
Even though some theories are incorrect, they often retain value. For example, Arrhenius acid-base theory does not explain the behavior of chemicals lacking hydrogen that behave as acids. The Bronsted Lowry and Lewis theories do a better job of explaining this behavior. Yet, the Arrhenius theory predicts the behavior of most acids and is easier for...
The scientific method leads to the formulation of both scientific theories and laws. Both theories and laws are falsifiable. Both theories and laws help with making predictions about the natural world. However, there is a key difference. A theory explains why or how something works, while a law describeswhat happens without explaining it. Often, yo...
A hypothesis is a proposition that is tested via an experiment. A theory results from many, many tested hypotheses.
Theories depend on facts, but the two words mean different things. A fact is an irrefutable piece of evidence or data. Facts never change. A theory, on the other hand, may be modified or disproven.
Both theories and models allow a scientist to form a hypothesis and make predictions about future outcomes. However, a theory both describes and explains, while a model only describes. For example, a model of the solar system shows the arrangement of planets and asteroids in a plane around the Sun, but it does not explain how or why they got into t...

Key concepts. Terms you should know. Imagine yourself shopping in a grocery store with a good friend who happens to be a chemist. Struggling to choose between the many different types of tomatoes in front of you, you pick one up, turn to your friend, and ask her if she thinks the tomato is organic.
A scientific theory is an explanation of an aspect of the natural world and universe that can be (or a fortiori, that has been) repeatedly tested and corroborated in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled ...
