You may not even think that the opening of the vast world of power applications is due to a famous controversy about frog legs.
One day in November 1780, the Italian biologist Galvani 1 was cooking in the kitchen as he prepared a local traditional delicacy - braised frog legs. Galvani was used to experiments, so even when cooking, he used to use a scalpel for cooking operations. The wife, who was watching her husband cook, plucked her leg on a whim with the tip of a scalpel.
Unexpectedly, when the tip of the knife touched the nerve on the frog's leg, the dead frog actually trembled a few times, and the wife who mistakenly thought that the frog had come back to life was frightened and screamed loudly. Galvani became intensely curious about this phenomenon and subsequently began related scientific research. Soon after, Galvani announced that he had discovered animal electricity.
After Galvani's paper on animal electricity was published, his discovery of animal electricity and the method of stimulating animal electricity caused an unprecedented sensation in Europe at that time. Many of Galvani's close friends came to congratulate him, except for one friend named Alessandro Volta 1, who disagreed with Galvani's opinion. In fact, at first, Volta still believed in Galvani and thought that Galvani had made a genius discovery, but after some research, Volta realized that something didn't seem to be right - the frog would only twitch when two metal wires of different materials were used to touch the frog's legs; If you just touch the frog leg with a metal wire of the same material, the dead frog will not react in any way.
Volta believes that the phenomenon of frog tics is not due to animal electricity in the organism, but to the metal in contact with the wet frog legs, and the frog is only affected by the electric current generated by the metal after contact with the wet animal muscles.
In the same way, Galvani and Volta came to two very different conclusions, which led to the very famous frog-legged controversy in the history of science. The controversy is divided into two factions, one represented by Volta, who believes that the frog's twitching is due to the connection of electricity; The other group is represented by Galvani and his nephew, who firmly believe that the frog's twitching is a manifestation of animal electricity.
From the initial oral argument between the two sides, it gradually evolved into a controversy that appeared in the newspapers and shouted through the media, and the fighting intensified.
