The video released by Li Yongle three years ago of a drop of water lifting a 10,000-ton ship has recently triggered a new round of controversy. Many netizens questioned the error of his statement and asked him to admit his mistake. Li Yongle recently issued a response, making it clear that he would never admit his mistakes and stick to his own views.
He explained that in reality, not to mention a drop of water, not even a glass of water can float a giant ship. If it is spread on the bottom of the ship, it will evaporate instantly. Everyone knows this.But this statement itself uses scientific reasoning to explain Archimedes' principle.
Buoyancy is only related to the volume of water displaced, not the total amount of water. As long as the shape of the ship is appropriate and there is enough space around it for the water to form a "groove" that matches the bottom of the ship, theoretically, as long as there is a very small amount of water, the ship can float, just like Galileo's inclined plane experiment, which is a reasoning method for an ideal experiment.
Many people misunderstood that he wanted a drop of water to cover the bottom of the boat, but this was not his original intention.He just wanted to use this extreme example to let everyone better understand the difference between displacement and water volume, and understand the nature of buoyancy.He said that science is not only true if it can be realized in reality, but it is valuable if it can help people get closer to the truth.
Faced with demands from netizens to force him to admit his mistakes,He stated his position directly and would never admit his mistake because he adhered to the scientific spirit rather than a simple conclusion.As for the marketing account saying that he founded a new physics teaching, he also said that everyone should not pay attention to it and just treat it as a joke.
