After a pause, the emperor continued, "Well, I'm going to call this new instrument a microscope."
"A mirror that shows microorganisms." Zhang Yita nodded thoughtfully and said, "Single lenses have been developed to this extent, and I thought it was the limit. What Brother Shen said is very feasible. Optics, well, I will study it seriously. But if Brother Shen makes a microscope first, don't be too proud of it, and make sure to let me open my eyes."
Zhu Youxiao smiled and nodded slightly, saying, "There are so many things to do, I'm afraid I can only think about it. Brother Zhang, if you study hard, you will definitely be able to develop a microscope soon."
Xu Fuyuan was a little puzzled and asked, "Brother Shen, may I ask, what is the practical significance of spending so much time and effort to build this microscope?"
Zhu Youxiao pondered for a moment and said, "Brother Xu, do you know why the wound is swollen, or pus is flowing, and even life-threatening?"
Xu Fuyuan frowned, thought for a moment, and shook his head, "I don't know."
Zhu Youxiao said, "That's because the wound is infected. Microorganisms invisible to the naked eye are multiplying in the wound. If we have a microscope, we can see what microorganisms are causing the damage and what we can use to kill them."
"Boiling water—" Wang Jizhong blurted out, and then he couldn't help laughing, "The injured person was also scalded to death!"
Several students also laughed, thinking that Wang Jizhong's words were too casual, which was a bit funny when they thought about it.
"Some microorganisms are harmful to humans, but some are beneficial," Zhu Youxiao said with a smile. "At first, you might think it's useless to use a mirror to observe things you can't see with your eyes, but if you study it in depth, you'll find that's not the case."
Zhu Youxiao stood up, looked around at the students, and said loudly: "Isn't the principle of the operation of all things what we are exploring? We are familiar with it in our daily lives, but often do not know the underlying principles."
He pointed at the table and said, "Why are four-legged stools the most stable? A three-legged stool can also maintain balance. Why are two-legged stools unstable, except for people?"
"Those who have read the book carefully must know that this is a problem of center of gravity. If you encounter a loader, you will not put heavy objects on it, thus avoiding unnecessary trouble."
"Some might say that learning these things might not be useful, and that life was fine even without them." Zhu Youxiao pursed his lips, revealing a hint of disdain. He continued, "But think about it, everyone: from the Shang and Zhou dynasties, or even earlier, the era of the Three Sovereigns and Five Emperors, to the present, what would have happened if there had been no advancement in science and technology?"
Everyone's face showed confusion and contemplation, and they blinked slowly. For a moment, they could not imagine the scene that "Shen Lang" had assumed.
