Five scientific theories?

Question

I need five scientific theories for science.For example the Big Boom.If you cant think of five its ok just write as many as you kinow.I dont even care if you know just one.just write the ones you know.thank you.

I meant the Big Bang

Answer 1

The heliocentric theory. Copernicus, primarily. Verified.

Universal Theory of Gravitation. Newton. Verified, and fundamental to almost all aspects of astronomy.

The Lamarckian theory of inheritance. Refuted.

The theory of evolution, (by natural selection). Darwin, et al. This has been verified to the point of being irrefutable fact.

Atomic theory. Rutherford, et al. Also verified. (Actually Aristotle was the first on record to hypothesize the existence of atoms.)

Theory of the luminiferous ether. Refuted.

The theory of Relativity. Einstein. Verified, but still debated in some of its implications.

Plate tectonics/continental drift. Weggener. This was once a theory and has been verified.

Quantum Mechanics. Neils Bohr. Looks good. Still a work in progress.

Theory (or theories) of abiogenesis. Still being built and debated, but certain points are agreed on by most scientists.

The Big Bang, you already mentioned.

I went back and put these in roughly chronological order.

Answer 2

As much as I hate to correct KWB3, but I would put a lot harder cuts on theories than he does:

- The heliocentric theory. Copernicus, primarily. Verified.
Not a theory , just a model. It takes a bit more than that to form a theory.

- Universal Theory of Gravitation. Newton. Verified, and fundamental to almost all aspects of astronomy.

Not a theory, just part of a theory called classical mechanics.

- The Lamarckian theory of inheritance. Refuted.

Obviously not a theory because it failed. Just another hypothesis which bites the dust.

- The theory of evolution, (by natural selection). Darwin, et al. This has been verified to the point of being irrefutable fact.

Now we are talking! About as fundamental to biology as thermodynamics is to physics.

- Atomic theory. Rutherford, et al. Also verified. (Actually Aristotle was the first on record to hypothesize the existence of atoms.)

I would probably take that, at least as part of atomic physics.

- Theory of the luminiferous ether. Refuted.

A failed hypothesis. It was supposed to be part of the theory of electromagnetism.

- The theory of Relativity. Einstein. Verified, but still debated in some of its implications.

Completely verified. Not debated at all.

- Plate tectonics/continental drift. Weggener. This was once a theory and has been verified.

Don't know. Would need to ask a geologist about its status as a theory or part of a greater theory. But I agree... completely verified.

- Quantum Mechanics. Neils Bohr. Looks good. Still a work in progress.

Theory, yes. Work in progress, no. This was basically complete in the 1930s. Everything you see now are applications.

- Theory (or theories) of abiogenesis. Still being built and debated, but certain points are agreed on by most scientists.

Not a theory because it is not sufficiently verified. Just a hypothesis. Which we take to be correct in the fundamental idea but that is not enough to call it a theory. We need to have the detailed chemistry worked out.

- The Big Bang, you already mentioned.

Not a theory. Just a model within a greater theory. Verified to a point but still evolving.

Fundamental theories in physics (there are not that many!):

Classical mechanics (Newton)
Theory of relativity (special and general)
Electromagnetism
Thermodynamics
Quantum mechanics
Quantum field theory (this is more of a mathematical framework than a complete theory because it puts little emphasis on observational evidence)

Applied fields which can be considered collections of minor theories and applications of fundamental ones:

Atomic physics (uses QM, EM, TD, SR)
Molecular physics (QM, EM, TD, SR)
Nuclear physics (QM, EM, TD, SR)
Elementary particle physics (QFT, EM, TD, SR)
Cosmology (all of the above)
Magnetism(QM, EM, TD)
Superconductivity (QM, EM, TD)
Solid state physics (QM, EM, TD)
Plasma physics (EM, TD, nuclear physics)
Semiconductor physics (QM, ED, TD)

I have to say, though, that physicists do not consider minor theories like BCS
(Bardeen, Cooper, Schrieffer) as nearly as fundamental as mechanics, quantum mechanics or thermodynamics. Einstein went so far to call thermodynamics the
only theory that would never be falsified. I would have to agree with him.

The other important observation to make is that theory building does not seem
to be as important to scientists as it is to people without science background.
The main reason is that theories build themselves and there are very few people who came up with a complete theory all by themselves (arguably not even Einstein or Newton fall into that category). So in the life of a mortal scientist this stuff does not matter as much as the next unsolved problem. And once you know your field, the important stuff is self-explanatory, you don't need anyone to order the material for you.

Answer 3

complex thing. try searching onto google and yahoo. this might help!
