The development of science is inseparable from exploration and experimentation. Every technological discovery causes a sensation and debate in the scientific community. Science has truth only in constant debate and experimentation.
At the time when the Leiden bottle was first invented, most people only thought of it as a tool of entertainment, and only a few people, like Franklin and the German scientist who unfortunately died, were willing to dig deeper and explore electricity.
When it was discovered that the lightning in the sky and the electricity in the Leiden bottle were the same thing, scientists began to think about a new question: electricity, this powerful energy, in addition to the ability to make people jump, what other uses does it have?
The more famous is "a famous controversy about frog legs", which opened up a vast world of power applications.
One day in November 1780, the Italian biologist Galvani was cooking in the kitchen as he prepared a traditional local 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, picked the frog's leg with the tip of a scalpel on a whim.
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 science
Study. Soon after, Galvani announced that he had discovered animal electricity.
After Galvani's paper on animal electricity, his discovery of animal electricity and the method of excitation of bioelectricity 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, who disagreed with Galvani's opinion.
Volta believes that the frog's twitching phenomenon 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 produced after the metal comes into contact with the wet animal muscle
Twitches occur due to the influence of the generated electric current.
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 contact with 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.
Scientific discoveries and inventions, under constant debate, with the participation of more and more scientific personnel, the truth will be revealed to the world. This book will take you into the temple of science and learn about scientific discoveries and inventions.
The highlight of technological development
