Following Gigers death in 2014, a plant breeder named Matthew Kaelin named a carnivorous species Nepenthes H.R. Wilson noted that Dr. T. J. Trenn, a modern physics scholar, characterized Geiger's and Marsden's work of this period: "It was not the Geiger-Marsden scattering evidence, as such, that provided massive support for Rutherford's model of the atom. Geiger moved from the Reichsanstalt in 1925 to become professor of physics at the University of Kiel. Giger because of its spikes and peristome teeth. Hans Geiger was awarded with the Hughes Medal in 1929 "for his invention and development of methods of counting alpha and beta particles". The creatures in Alien: Resurrection are even closer to my original Alien designs than the ones which appear in Aliens and Alien 3, he wrote. Yet, when Geiger and Marsden conducted their eponymous experiment, they found that in about 2% of cases, the -particle underwent large deflections.

Despite these failings, the Rutherford model derived from the Geiger-Marsden experiments would become the inspiration for Niels Bohr's atomic model of hydrogen, for which he won a Nobel Prize in Physics. Geiger continued to study the scattering effect, publishing two more papers about it that year. Even with this random scattering, the maximum angle of refraction if Thomson's model was correct would be just over half a degree. Alternate titles: Johannes Wilhelm Geiger.
