Karl Jaspers (1883–1969) was born into an upper-middle-class family. He was a sickly child but it was only in April 1901 that bronchiectasis was diagnosed. This was a lifelong condition that influenced his choice of career but also his outlook as he was not expected to live long. Jaspers studied medicine in Berlin, Göttingen and Heidelberg. At Heidelberg, he came into contact with many of the l...

Karl Gebhardt (1897–1948) had a distinguished career as professor of sports medicine before the Second World War. He developed sports for the disabled at a specialised orthopaedic clinic at Hohenlychen and was President of the Red Cross in Germany. During the war, Gebhardt also acted as Heinrich Himmler’s personal physician and was responsible for medical experimentation on prisoners in the con...

This article investigates the historical method of Karl Sudhoff (1853- 1938), Germany's first professor of medical history. It argues that in order to understand his ideas more fully, we need to step outside the historiography of medical history and assess his methodology in relation to the norms and ideals of German academic history writing in general. The article demonstrates that the philolo...

We show that in the dissipative quantum model of brain the time-dependence of the frequencies of the electrical dipole wave quanta leads to the dynamical organization of the memories in space (i.e. to their localization in more or less diffused regions of the brain) and in time (i.e. to their longer or shorter life-time). The life-time and the localization in domains of the memory states also d...

Karl Popper, though not trained as a physicist and embarrassed early in his career by a physics error pointed out by Einstein and Bohr, ultimately made substantial contributions to the interpretation of quantum mechanics. As was often the case, Popper initially formulated his position by criticizing the views of others—in this case Niels Bohr and Werner Heisenberg. Underlying Popper’s criticism...

We characterize matrices A ∈ Cn×n whose zero/nonzero pattern requires that the controllability matrix [b Ab Ab . . . An−1b] ∈ Cn×n is of full rank, where b ∈ Cn×1 has exactly one nonzero entry. When all the diagonal entries of A are nonzero we show that this occurs if and only if QAQ is unreduced upper Hessenberg, with Q being a permutation matrix for which Qb = [b1, 0, . . . , 0] T . We also c...
