For example, since the federal government provides about half the funding for scientific research in this country, it's become easy for national politicians and bureaucrats to silence politically incorrect science.
Money is to scientific research as electricity is to a light bulb.
Turn the money on and light the lamp of knowledge. Turn off the juice, and we're back in the dark. Science is even more resourceful than Batman. And science has a major ally. The American public still likes science and has high hopes for it.
