No, mathematics is not science.
Mathematics can be applied to science, and to the extent that it models the variables correctly, it can produce useful results. But that's the key--did that mathematical model use the correct variables correctly, and did it weight them correctly? Mathematicians are good at math, but not necessarily at biology.
Here is a counter example, a biologist who is pretty good at math. And he comes up with entirely different results:
Making Genetic Networks Operate Robustly: Unintelligent Non-design SufficesHow are you going to deal with that?
Online lecture by Professor Garrett Odellhttp://www.researchchannel.org/prog/displayevent.aspx?rID=2513
Description: Mathematical computer models of two ancient and famous genetic networks act early in embryos of many different species to determine the body plan. Models revealed these networks to be astonishingly robust, despite their 'unintelligent design.' This examines the use of mathematical models to shed light on how biological, pattern-forming gene networks operate and how thoughtless, haphazard, non-design produces networks whose robustness seems inspired, begging the question what else unintelligent non-design might be capable of.
The central activity of mathematics is applying strict formal rules of logic to produce theorems from arbitrary human-invented axioms. Theorems are proven, and once proven are eternally valid.
The central activity of science (as I understand it) is applying the scientific method to produce theories from data gathered in experiments. Theories are tentative, and are eventually replaced by "better" theories.
I say this mostly as an excuse to point out a particular idiocy of the idiot Karl Priest. From his monumentally idiotic lesson plan:
"1. Students will comprehend that the science of mathematics proves that life could not have developed by natural (evolutionary) means.
...
4. Discuss the scientific method (use the schools science book definition). Emphasize that evolutionists have failed to follow the scientific method. Middle school teachers will see a cross-content teaching opportunity here."
So this Priest, this harebrained hairball, contends that biologists have failed to follow the scientific method. But somehow his remedial grasp of the subject he claims to teach has prevented him from realizing that the scientific method shows up nowhere in mathematics. How can any semi-educated person swallow this bull excrement?
And some biologists are absolutely amazing mathematicians: Ronald Fisher.
