Theoretical chemistry uses physics to explain or predict chemical observations.
It can also be used as a model to explain experimental observations of neural activity to a certain extent.
"Science" is a way of explaining and classifying observations.
Detractors have asserted that neither the overkill nor climate change hypotheses can explain several observations.
Additional knowledge can be obtained by proving (or falsifying) existing theories and by trying to better explain observations.
This new theory explained more experimental observations than previous theories, and its mathematics also made further testable predictions that could be confirmed.
Their existence is necessary to explain observations of elements other than hydrogen and helium in quasars.
To me, the role of science is to explain observations, and as our observations get better, so do our explanations.
Instead, hypotheses stand or fail on their ability to explain known observations, and to predict the outcome of observations that haven't been performed yet.
This discovery explained observations that had puzzled elephant watchers.
