A joke about eating potatoes

Papin ate a potato and invented the pressure cooker. Where did his inspiration come from? More than 300 years ago, a young French doctor, Papin, was forced to flee abroad. He trudged along the Alps, intending to seek asylum in Switzerland. Papin slept all the way, eating potatoes and quenching his thirst with mountain spring water. One day, Papin came near a mountain. He felt very hungry, so he cooked rice and potatoes in the pot. Boiled several times, the potatoes are still not ripe. He had to wolf down immature potatoes to fill his stomach. This incident left a deep impression on him.

Inventions have changed people's lives, but what you may not know is that many inventions in history are accidental. Many people think that many great inventions in the history of science are the result of scientists' efforts, but in fact, many famous inventions in human history are the result of "luck".

Papin made a sealed container himself. He will heat the container to increase the amount of steam in it and keep it there. Therefore, the pressure in the container increases, and the boiling point of water is higher and higher. Two years later, Papin drew a drawing of pressure cooker according to his new idea, and invited a technician to help him make it. When the pot is ready, Papin puts the potatoes in the pot, lights the fire, and then stares blankly. 10 minutes later, the potatoes are ripe.

168 1 year, Papin made his first important invention, namely "digester", which became the original pressure cooker. Using the principle that the greater the steam pressure in the sealed container, the higher the boiling point of water, saving a lot of time. Papin cooked the ribs in the earthen pot like food, and invited members of the Royal Society to a scientific dinner to taste the power and achievements of the earthen pot. Later, people used the name "pressure cooker" instead of "digester". Pressure cooker can effectively sterilize in medical treatment. Pressure cookers are particularly useful in high mountains and plateaus, where the pressure is low and the boiling point of water is low. It was not until 1687, when Papin was 40 years old, that he had a formal title: Professor of Mathematics at Marburg University in Germany. He knew that his knowledge would be very useful in machinery, so he continued his research and experiment, and in less than a year he invented a centrifugal pump for urban water supply and mine ventilation.
