Biological knowledge evolved from the collective activity of many investigators who focused more or less exclusively on their individual tasks, like ants in a nest. Consequently biology is presently uninformed by any explicit overall conception similar to that achieved in physics, except for a common naïve belief that physics will eventually explain whatever biologists regard as facts. Because biologists don’t understand physics, they don’t see that explanations for the matters of interest to them cannot be achieved by thinking like physicists. Biologists must begin to think for themselves and develop their own cognitive structure. A necessary step in that direction is to learn physics. Biologists who do so will see that even though physics is conceptually trivial and irrelevant, nevertheless it is methodologically useful for studying life. Armed with this methodology and a cognitive structure of their own design, biologists would be in a good position to understand the link between EMFs and disease, both acute and chronic.
