echophysics

On the desk of Victor Franz Hess from the Vienna Institute for Radium Research (in display in echophysics in Pöllau), the original instruments are displayed, which Hess carried with him on his decisive balloon flight on Aug. 7, 1912.

Thermal radiation measuring apparatus

Thermal radiation measuring apparatus for determining the T⁴ dependence of thermal radiation.

Joseph Loschmidt (1821–1895)

From J. Loschmidt's self-published Chemical Studies I of the 'Constitutions-Formeln der organischen Chemie in graphischer Darstellung' (1861).

Loschmidt - and not Kekulé - was the first to publish the benzene ring diagram.
