Other prominent physicists include: Amedeo Avogadro (most noted for his contributions to molecular theory, in particular the Avogadro's law and the Avogadro constant), Evangelista Torricelli (inventor of barometer), Alessandro Volta (inventor of electric battery), Guglielmo Marconi (inventor of radio), Galileo Ferraris and Antonio Pacinotti, pioneers of the induction motor, Alessandro Cruto, pioneer of light bulb and Innocenzo Manzetti, eclectic pioneer of auto and robotics, Ettore Majorana (who discovered the Majorana fermions), Carlo Rubbia (1984 Nobel
Marsilio Landriani to convince Landriani to change over to the new chemistry, but he never was able to decide between phlogiston and oxygen. After 1790 he dealt exclusively with chemical applications of electric phenomena, and the improvement of physics and meteorology instruments. During his career he enjoyed a popularity comparable only to that of Alessandro Volta and Lazzaro Spallanzani, of all Italian scientists of that time. Marsilio Landriani Marsilio Landriani (Milan, 1751 – Vienna, 1815) was an Italian chemist, physicist and meteorologist. He became known with his first book, (Physical investigations on the salubrity of air), published in 1775. In it he
