In the first half of the 19th century, physicists were not very interested in induction generators. On the contrary, starting in the 1860s, numerous prototypes of electrostatic influence machines were invented, such as the Holtz or Toepler influence machine, both from 1865. These devices were soon put aside, because others were invented, which had higher performances, such as that of Voss...
In 1898, Carl Evard Johansson, a rifle maker based at a factory based in Eskilstuna, Sweden, filed for a patent for Gauge Block Sets for Precision Measurements.” The invention was as simple as it was powerful. Instead of relying on thousands of different mechanical gauges, as was the practice in the small arm industry, he introduced a set of only 102 accurately polished blocks. Such blocks,...
One of the most significant discoveries of the NanoWorld are Carbon Nanotubes. Crossing the history of nanotubes through its historiographical––and––scientific literature, we analysed a) Radushkevich and Lukyanovich’s research On the Carbon Structure Formed by the Thermal Decomposition of Carbon Monoxide on an Iron Contact. In 1952, they observed and described tubular structures of carbon,...
