  1. Thaddeus J. Trenn (1986). The Geiger-Müller Counter of 1928. Annals of Science 43 (2):111-135.
    Ancillary to the emergence of nuclear physics in the 1930s, this important instrument soon became one of the most famous of all time. Yet little is known of its origin, how it differs from the Geiger Counter of 1913, or what role Walter Müller played in the invention of the Geiger-Müller counter of 1928. One of the most interesting features of this history is the absence of any ‘somking gun’—any specific novum for the assignment of credit unless it be the (...)

  2. Thaddeus J. Trenn (1981). Ludwik Fleck's 'on the Question of the Foundations of Medical Knowledge'. Journal of Medicine and Philosophy 6 (3):237-256.
    According to Fleck, a fact is not something objectively given but rather a social event. Scientific facts are no exception, as can be seen through the annals of medicine. Fleck argues that if the physical sciences initially appear to be immune to such social conditioning, this misconception can be corrected by recognizing the similarities between the natural sciences and medicine both historically and epistemologically. Fleck's ideas are not new, having been presented by him in 1935, but it is only recently (...)

  3. Thaddeus J. Trenn (1980). The Phenomenon of Aggregate Recoil: The Premature Acceptance of an Essentially Incorrect Theory. Annals of Science 37 (1):81-100.
    Postulated before 1920 to account for observations such as the fluctuating measured half-life of polonium and the unusual migration of polonium causing radioactive contamination throughout laboratories, by 1930 the phenomenon of aggregate recoil had become part of international textbook science. The formation of radioactive aggregates has been confirmed, but their migration is probably due either to volatility and diffusion or to electrostatic polarity and attraction. Knock-on recoil and sputtering may contribute to the release of such aggregates from solid surfaces, whereas (...)

  4. Thaddeus J. Trenn (1978). Thoruranium (U-236) as the Extinct Natural Parent of Thorium: The Premature Falsification of an Essentially Correct Theory. Annals of Science 35 (6):581-597.
    To explain the origin of thorium, the Austrian geophysicist Kirsch in 1922 postulated a hypothetical isotope, thoruranium , by analogy with actinouranium. The theoretical life-time of thoruranium was predicted as being too short for it to have survived in the recent geological past. Available geological data was not inconsistent with this hypothesis, but neither did it confirm it. Within five years one new piece of geological evidence, which appeared not to conform with predictions based upon this alleged U-236, was accepted (...)

  5. Thaddeus J. Trenn (1974). Rutherfords alpha-teilchen. Annals of Science 31 (1):49-72.
    It is with good reason that the name Rutherford is closely linked with the early history of the alpha particle. He discovered them, determined their nature, and from 1909 used them to probe the structure of the atom. From 1898 to 1902 Rutherford construed alpha radiation as a type of non-particulate Röntgen radiation. On his theory of the locomotion of radioactive particles Rutherford proposed that alpha radiation consisted of negatively charged particles. During 1902 he confirmed the particulate nature of alpha (...)
