On this day, 180 years ago, on August 16, 1845 (July 14, 1845 lunar calendar), the famous French physicist Lippmann was born. The physicist Lippmann Lippmann was a famous French physicist, born in Luxembourg on August 16, 1845. The father was Lorraine and the mother was Alsatian. Both of them were tutors in Luxembourg's aristocratic government, and their lives were comfortable. But they felt that they were French, and they should have their sons raised in the arms of their motherland. At the age of 3, despite repeated attempts by his master, Lippmann's parents resigned and left Luxembourg, returned to France, and settled in the Latin Quarter, the most cultural atmosphere in Paris. Lippmann was born in such a bookish family, and his parents were both down-to-earth, modest, and educated people. Their attitude towards learning was serious and meticulous. This played a subtle role in the formation of Lippmann's ideological character. Lippmann had big ambitions and could work hard. He was admitted to the Department of Education of the Ecole Normale Supérieure in Paris in 1868, but because he showed a strong interest in mathematics, he transferred to the Department of Physics the next year. During the next 10 years, he investigated all aspects of physics, especially for the development of experimental physics. In 1882, he applied to be a professor of mathematics and science at the University of Paris, and later became famous at home and abroad for his excellent results in experimental physics. In 1886 he was elected a member of the French Academy of Sciences. Lippmann had a deep knowledge of physics and a wide range of research, especially in electricity, heat, optics and optoelectronics. He made outstanding achievements. At that time, the European scientific community recognized him as an authority. One day, while entertaining the celebrities of the scientific community, he unreservedly presented his invention of the capillary potentiometer to the French Physical Society. At that time, if he applied for a patent in his country or other countries with this invention, he could immediately become a millionaire. His spirit of not being greedy for wealth and regarding scientific achievements as common to all mankind, and contributing to science and the motherland came from his mother's teachings. Lippmann is also the inventor of "color photographic interference". Due to his outstanding contributions, he was awarded the Nobel Prize in Physics in 1908 by the Royal Swedish Academy of Sciences. In 1912, Lippmann was elected president of the French Academy of Sciences. In 1921, Lippmann went to Canada and the United States to give lectures, fell ill abroad, and died on July 13 on his way back.
