Examples of discoveries, questions, and conclusions drawn by scientists from life

Newton's apple fell on Newton's head, and Newton discovered gravity.

Watt looked at the lid of the boiling water pot and discovered the principle of steam power. Archimedes.

Buoyancy is found in the common phenomenon of water spilling from the tank during bathing, and so on.

In the autumn of 1666, in a village called Ulsthorpe in Lincolnshire, in the north of England, a trivial incident occurred: one evening, Newton, who had studied all day, felt a little tired, and he wanted to rest. So he walked to his apple orchard, sat under an apple tree, and admired the fruit.

In the face of this wonderful and harmonious nature, Newton always vaguely felt that behind the mysterious natural world, there must be some kind of law governing its movement, but what is this law? The faint fragrance of apples unconsciously immersed Newton in the contemplation of the mystery of celestial motion. An apple falls from a tree that happens to happen.

At this time, it occurred to him that why did the apple always fall vertically to the ground? Why don't apples move outwards or upwards, but always toward the center of the earth?

Undoubtedly, it is the earth pulling it downward, there is a downward pull acting on the object, and the sum of this downward pull must be directed towards the center of the earth and not towards the rest of the earth. So apples always fall vertically, or always towards the center of the earth. The apple is facing the earth, which can also be seen as the earth facing the apple, and the objects are moving towards each other.

The force acting between the objects must be proportional to their mass. This force is what we came to call gravitational force.

Newton's main contributions.

In mechanics, Newton clarified the principle of conservation of momentum and angular momentum and proposed Newton's laws of motion. Optically, he invented the reflecting telescope and developed a theory of color based on the observation that a prism diverges white light into the visible spectrum. He also systematically formulated the law of cooling and studied the speed of sound.

In mathematics, Newton shared the honor of developing calculus with Gottfried Wilhelm Leibniz. He also proved the generalized binomial theorem, proposed the "Newtonian method" to approximate the zero point of a function, and contributed to the study of power series.

I'm so entangled with you, your uncle.

Yes, I am a scientist, a dying scientist, I am 76 years old, 30 years ago I asked my assistant: you say, can people not die? He said:

Expert, you are a master and I am just a doctor, you say I am just your rib hand, if you want me to say I will say, yes, there are about 50 billion planets in the universe that can be lived by people, but people want to invent something that makes genetic nucleic acids not lose and eat it. So I said to my assistant, "Then let's invent it."

He said, "Yes." At that moment, I had been doing it for more than 40 years, but just the two of us, and when I was 56 years old, my assistant unfortunately died, and before I left, he said something that I couldn't say.

He said: "Su Su, you must insist. Before I finished speaking, my assistant Liu Kunhe left this beautiful world.

When I was 60 years old, I was the only one doing it, and I occasionally heard someone say: Yan Su put aside his master's status and didn't look for a good job, but he studied things here that made people immortal. Ay.

But I didn't give up, I worked harder, and I didn't know I had colorectal cancer until yesterday. I just want to say: the scientists who saw it should also invent it.
