Mentioned in "Nine Chapters of Arithmetic"? Wednesday, the first game? . This? Wednesday, the first game? The approximate value of pi is 3. Liu Hui thinks that this result is too vague and inaccurate to be used as the value of pi. Liu Hui invented it? Circumcision? The origin of is also very interesting. Newton was hit by an apple under an apple tree and discovered the law of gravity. Liu Hui was inspired by watching a stonemason cut stones.
Liu Hui happened to see the stonemason's work, and thought the process was very interesting, so she took a look beside it. Masons cut off four corners of a square stone in turn, and then cut off eight corners from four corners in turn. By analogy, masons cut off these corners in turn until the stone becomes hornless and finally becomes a smooth pillar. As a stonemason, Liu Hui saw from beginning to end. He thought of the circle from the stone, and further thought of pi. He cut the circle step by step according to the stonemason's method, then calculated the pi, and finally got the definite value of pi. Every day I saw masons cutting stones, and only Liu Hui came up with a solution. Newton was not the only one who was hit by an apple, but also the discovery of the law of gravity. Successful people are good at observing life, getting inspiration from it and solving their own problems.
Liu Hui was inspired by masons to cut stones and invented it? Circumcision? It provides a feasible logical thinking and strict calculation method for future generations to calculate pi, and his deeds have been passed down by future generations to this day. Liu Hui is the famous author of Nine Chapters Arithmetic Notes and Arithmetic on the Island. These two works also play a great role in China's mathematics field.
