Galileo vs. Aristotle, which doctrine did Galileo overthrow Aristotle?

Two iron balls hit the ground at the same time.

Galileo overthrew Aristotle's doctrine that "the speed at which an object falls in proportion to its weight".

In 1590, Galileo Galilei did an experiment on the Leaning Tower of Pisa where "two iron balls hit the ground at the same time", and came to the conclusion that two iron balls of different weights fell at the same time, thus overturning Aristotle's theory that "the falling speed of an object is proportional to its weight", and correcting this erroneous conclusion that lasted for more than 1,900 years.

But this is unlikely, objects of different weights can only land at the same time under vacuum, and the law of free fall was proved when American astronaut David Scott tried to drop a feather and an iron hammer at the same height at the same height after landing on the moon, and found that they landed at the same time.

Even if Galileo did do this experiment, it was limited to the level of technology at the time, so it "seemed" to land at the same time. Regarding the free fall experiment, Galileo did a lot of experiments, he stood on top of the leaning tower and made objects of different materials fall from the top of the tower, and measured the difference in the time of falling.

It was found that all kinds of objects landed at the same time, in no particular order. In other words, the falling motion is not related to the specific characteristics of the object. Regardless of whether the ball is wooden or iron, if it starts falling from the tower at the same time, they will reach the ground at the same time.

Through repeated experiments, Galileo believed that the free fall velocity of light and heavy objects is the same, that is, the magnitude of gravitational acceleration is the same, regardless of air resistance.

Galileo Galilei (15 February 1564 – 8 January 1642). Italian mathematician, physicist, astronomer, pioneer of the scientific revolution. Galileo Galilei invented the pendulum needle and thermometer, made great contributions to mankind in science, and was one of the founders of modern experimental science.

Aristotle (384 BC 322 BC), an ancient philosopher, an ancient Greek, one of the great philosophers, scientists and educators in the ancient history of the world, can be called the master of Greek philosophy. He was a pupil of Plato and a teacher of Alexandria.

Aristotle and Galileo were both famous ancient philosophers and scientists who made unique contributions to the observation and understanding of the natural world. Their views on the world are significantly different, so let's take a look at their views.

According to Aristotle, the world is made up of many different substances, all of which have their own properties and characteristics. He divided matter into four elements: earth, water, fire, and air, and believed that all matter was made up of these elements.

He also put forward the concept of "metaphysics", which holds that there is some form or essence in matter that transcends the matter itself. He believed that human beings could understand the nature and laws of various things in nature by observing their nature and characteristics.

In contrast, Galileo studied the early lack of cherry blossoms in nature from the perspective of experiments and observations. He believed that all objects follow the laws of nature, which can be determined through experiments and observations. His ideas were very bold and avant-garde at the time, and he proposed the theory of ether and the theory of relativity, which had a huge impact on the scientific community at that time.

In general, Aristotle and Galileo have significantly different views. Aristotle focused more on the study of metaphysics and essence, while Galileo focused more on the importance of experimentation and observation. These two great philosophers and scientists have made very important contributions to our understanding of the laws and nature of the natural world.

Aristotle was a Greek philosopher.
