A little story about questioning .

1. Bruno.

This natural scientist, who cried out for the truth, defied the ban of the Church and boldly exposed the ignorance of religion. He organically combined the advanced natural sciences and philosophy of the time to establish his own materialist natural philosophy cosmology. He insisted on supplementing and developing the Copernican doctrine.

Copernicus lowered the earth from the center of the universe to a planet in the solar system, thus shaking the foundations of Catholic theological domination.

2. Galileo.

Galileo challenged Aristotle about the "Leaning Tower of Pisa Experiment" Galileo used two iron balls of different weights on the Leaning Tower of Pisa to come to a conclusion: when objects are in free fall, they do not show different speeds due to weight Aristotle believes that the speed at which objects of different weights fall from a height is proportional to their weight, and the heavier ones must fall to the ground first.

3, Zhong Nanshan.

When SARS first came out, many medical authorities in China believed that chlamydia was pure and auspicious, but Academician Zhong Nanshan made another discovery, he boldly questioned and repeatedly insisted on his own point of view, believing that it was the coronavirus, which made great contributions to the rapid diagnosis and treatment of patients at that time.

4. Huygens.

Newton thought of light as a stream of particles, and used it to explain phenomena such as linear propagation, specular reflection, and interfacial refraction of light. Huygens, however, had a different view, arguing that the particle theory could not explain more complex phenomena such as diffraction and interference, and that light was an aether wave, and that it was the truth.

Because of Newton's high prestige, the majority supported the particle theory, and Huygens became an isolated minority But he did not follow the crowd, did not believe in authority, insisted on independent opinions, and as the research deepened, by the beginning of the 19th century, the wave theory prevailed over the particle theory.

5. Outer Carters.

In his research, the German mathematician Schwai Carter questioned a theorem in Eucliché's Principia Geometry: the sum of the internal angles of a triangle is equal to 180°. For more than 2,000 years, people have thought that this is a natural and universal theorem, and scientists are convinced of the truth of this theorem.

But this questioning of Outer Carter drove a sudden change in mathematics. The German mathematician Riemann was inspired by the ideas of the Outer Cart, and the non-Euclidean set broke ground. Riemann pointed out that Euclidean geometry is not applicable in all spaces, for example, on the surface of the earth, the sum of the internal angles of a triangle is greater than 180°.

The Americans Adam and Jimmy, who once questioned Archimedes' use of mirror reflection to burn the Roman warship, went to the experiment again, and found that the Roman warship was not burned, but the Roman commander found that the temperature of the warship had risen very high, and he was afraid that the warship would burn, so he withdrew from the army.

In the answer class, the philosopher Socrates took out an apple, stood in front of the podium and said, "Please smell the air." One student raised his hand and replied, "I smell it, it's the scent of apples" Socrates stepped down from the podium, slowly walked past each student with apples, and admonished:

Let's take a closer look and see if there is any smell of apples in the air," at this time, half of the students raised their hands. Socrates returned to the pulpit and repeated the question. This time, all but one student did not raise their hands.

Socrates walked up to the student and asked, "Don't you really smell anything," and the student affirmed, "I really don't smell anything."

At this time, Socrates announced to the students: "He is right, because it is a fake apple." This student was the famous philosopher Plato.

1.If you learn without thinking, you will be reckless, and if you think without learning, you will die. (Confucius).

1.Dai Zhen, a scholar and thinker in the Qing Dynasty, asked Zhu Xi when he was a person and how he knew about it more than 2,000 years ago when his teacher explained the "University Chapters and Verses".

2.Newton's thinking about the apple landing proposed the law of gravitation.

Galileo boldly questioned Aristotle's doctrine and proved through experiments that his views were not correct and that his own ideas were correct.

Aristotle of Greece believed that objects fall differently and slowly. The speed at which it falls is directly proportional to its weight, and the heavier the object, the faster it falls. For example, an object weighing 10 kg will fall 10 times faster than an object weighing 1 kg.

For more than 1,700 years, people have regarded this doctrine, which is contrary to the laws of nature, as an unquestionable truth. The young Galileo, reasoning from his own experience, boldly questioned the doctrine of Aristotle. After much deliberation, he decided to do a hands-on experiment.

He chose the Leaning Tower of Pisa as his testing ground.

On this day, he brought two iron balls of the same size but different weights, one weighing 100 pounds and being solid; The other weighs 1 pound and is hollow. Galileo stands on top of the Leaning Tower of Pisa and looks down. The tower was full of people who came to **, and everyone was talking.

Someone sarcastically said, "This young man must have a sick nerve!" Aristotle's theory can't be wrong!

The experiment began, and Galileo took an iron ball in each hand and shouted: "You see, people below, the iron ball is about to fall. With that, he opened both hands at the same time.

It was seen that two iron balls fell parallel to each other, almost simultaneously on the ground. Everyone was dumbfounded.

Galangelio's experiments revealed the secret of the motion of the falling body and overthrew Aristotle's doctrine. This experiment is of epoch-making significance in the history of physics.
