The Female Engineering Major Traveled Through the Warring States Period: Flirting with Crazy Mozi and Torturing Lu Ban to Tears

[Ink Attack: Mortise and Tenon] Engineering girl in the Warring States Period: Flirting with Crazy Mozi and torturing Lu Ban to tears One afternoon in 444 BC, I woke up among a pile of corpses. My name is Ma Jingyi, and I am studying for a PhD in materials mechanics. The first person to be killed was using the principle of leverage. The next day. I met Mozi. He was fixing a broken car and I told him he was doing it the wrong way. He looked at me as if he were looking at an interesting piece of wood. It was many years before I understood that look. We use arithmetic to solve equations on the ground. The moment we untied it, we looked at each other and smiled. The surroundings were filled with the stench of corpses and gunpowder smoke, but at that moment, the world was clean. Someone asked him what the relationship between tenon and tenon was. He said, if it gets red hot, stuff it in, and if it gets cold, you can't pull it out. That's called giving up one's life. He didn't look at me. I didn't look at him either. But I know what he's talking about. Physics textbooks 2,400 years later called it 'interference fit'. I was in the Warring States Period, so I called it—— Forget it, it's not important. The important thing is that I still remember the burning smell in the workshop that day.
