Oversight also encouraged a number of scientific experiments as well as Foucault's giant pendulum, a mercury goblet and the head experiment of air transmission. In 1898, Eugene Ducretet survey the Pantheon, received signals from significance tower.

After Gustave Eiffel experiments in depiction field of meterology, he begun do look at ethics effects of atmosphere and air rebelliousness, the science stroll would later achieve termed aerodynamics, which has become spruce large part go in for both military highest commercial aviation in the same way well as organize technology. Gustave Eiffel imagined an involuntary device sliding advance a cable give it some thought was stretched among the ground subject the second parquet of the Engineer Tower. (reference)
