-- Does it explain things that have already been observed ?-- Does it make predictions that can be tested, and when tested, are found to be true ?
Scientists make observations about the natural world through experiments and try to explain the phenomena that they observe. Scientists then attempt to explain the occurence of all of these observations in an overarching theory. For example, an observation would be seeing an apple fall to the ground and making measurements. The next step would be taking all of these observations which could include things such as the movement of planets and other cosmic bodies to form the theory of gravity which attempts to explain these observations.
There are many things that happen when you block light with an object. Some of the common things that would happen include reflection and refraction of the light.
Speed of light is constant, not the other things.
quantum theory
Scientific Theory.
it can change by any time or any day because new things happen everyday in life or literally on earth
To explain how things happen
to explain how things happen
Theory provides a framework for organizing and understanding our observations and experiences. It helps to explain why things happen the way they do and can guide future research and application. Additionally, theory can lead to the development of new ideas, technologies, and practices.
-- Does it explain things that have already been observed ?-- Does it make predictions that can be tested, and when tested, are found to be true ?
Scientific theories do not " prove " things, they explain things. So, before the big bang is not yet explained, as an example.
charles darwin prposed the 1st theory to explain the formation of life on the earth
Two means of testing the validity of a hypothesis: -- Does it adequately explain things that have already been observed ? -- Can observations of its predictions be achieved ? If a hypothesis passes both of these tests, it then becomes a theory.
The statement is basically saying:Science tells you why things work Science deals with the theoretical principles.Technology tells you how to make things work.Technology deals with the practical application of the theory and sometimes succeeds by trial and error if the theory is not known.
Because it helps explain many of the things that happen around us. The understanding enables us to design new and better ways of doing things.
