[Philosophers, physicists and physicians in defense of the unity of the scientific method]

The falsifiability of scientific knowledge is an acquired result of contemporary philosophy of science and yet there is not a universal consensus upon the idea of the unity of scientific method. Albeit there are differences in techniques of testing (methodics) hypotheses in the vast field of research, the author, following the critical rationalism of Karl Popper, favors the perspective of the unity of method in natural as well in social and philological sciences.
