How do scientific theories come about? By experimentation?

Scientific theories may have been derived through ideal experiments. Such as Newton's first law.

If we ignore the effect of friction, we find that after the ball rolls down from the left and then rolls up from the right slope, the ball will rise to the same point as the left release and then stop; If the angle of inclination on the right side is reduced, the ball will still rise to its original height and stop, but the distance it passes is longer than the original; Assuming that the bevel on the right is horizontal, the ball will reach its original height, but the ball will not reach its original height, and the ball will always move in a straight line at a uniform speed.

1. The purpose of the three experimental balls to slide down from the same height of the inclined plane is to ensure that the steel ball obtains the same initial velocity when it reaches the horizontal plane.

2. Conclusions from experiments: On the basis of some experiments, "ideal experiments" are made in the way of "theoretical reasoning", and the conclusion that "the motion of objects does not need force to maintain" is obtained. In fact, when the ball moves on a horizontal plane, it eventually has to stop because it is the result of friction and air resistance.

3. Through the "ideal inclined plane experiment" and scientific reasoning, Galileo came to the conclusion that force is not what maintains the motion of objects. The French scientist Descartes supplemented and perfected Galileo's ideas when he proposed:

I hope I can help you with your doubts.

1. Observe the objective facts first, and summarize the laws of a large amount of data.

2. Put forward theoretical hypotheses.

3. Under the guidance of the theory, carry out systematic experiments or systematic observations, verify the theory, deny the theory, or discover the flaws of the theory.

4. Prove, revise or deny the theory, and so on, and keep improving.

Most scientific theories are deduced through theories, and some theories can be concluded through experiments, such as Ohm's law, which is first obtained through experiments. Subsequently, we will add applications on top of this. Some laws are derived theoretically, such as the Pythagorean law.

The establishment of a general scientific system takes several generations to complete.

First of all, science is the explanation of social, natural phenomena that can be used by man. There needs to be a leader to pave the way and build a set of mathematical models. Then go to the experiment to verify the correctness of the results.

In the end, it is used and applied to all aspects of life. This process requires generations of continuous supplementation of theories.

Different theories** may be different, and generally first through experiments, and then generalized on the basis of experiments.

Professor Shepiro discovered that the whirlpool of bathwater always rotates in the same direction, and after continuous research, the discovery was related to the autobiography of the earth. (Swirl of bathwater).

2.The famous British chemist Boul Yi dropped hydrochloric acid onto the petals of the violet. It was discovered that it would change color, and after continuous experimentation, litmus paper was invented. (discoloration of violet).

3.I thought that the Austrian doctor found that his son was dreaming when he was sleeping, and after constant observation, it proved that when the sleeping person's eyes were rolling, he was indeed dreaming. (Roll of the eyes while sleeping).

4. Newton continued to study and discover the gravitational force of the apple.

5. When Luban went up the mountain, his hand was scratched by a plant, and he invented the saw.

6、.Edison – Invention of the electric light.

7、.Galileo – Two iron balls hit the ground at the same time.

8. Watt – Invented the steam engine.

Summary. Hello, <>

Dear, scientific theories must be derived through experiments. Scientific theories are derived through research and experiments, and experiments are one of the important means of scientific research.

Scientific theories do not have to be derived through experiments?

Hello, <>

Dear, scientific theories must be based on experiments. Scientific theories are derived from research and experiments, and experiments are one of the important means of scientific research.

Dear, <>

Scientific theories are generalizations and summaries of experimental data and observations, as well as explanations of natural phenomena and laws. The scientific theory of the source of dismantling the noise requires a certain degree of verifiability and reproducibility, which requires that the scientific theory must be verified by experiments. The results of experiments can be used to verify or falsify a scientific theory, and then advance the development of science.

Dear, <>

The formation of scientific theories is not only through experiments, but also requires rational thinking and the application of scientific methods. The formation of scientific theories requires scientists in the world to reason and summarize based on experimental data and observations, so as to put forward some hypotheses or conclusions, and then verify or falsify these hypotheses or conclusions through experiments. <>

Some of them were discovered by the eyes of scientists.

For example, there are instruments that observe atoms and molecules.

Dear, that also needs to be verified through experiments.

What if some can't be experimented?

For example, scientists have discovered planets in space.

Dear, they will be repeatedly verified, and finally a conclusion will be drawn.

So what are the methods of scientific theory?

Dear, <>

There are several methods of scientific theory: 1. The induction method of lead and silver. 2. Deductive method. 3. Experimental method. 4. Simulation method. 5. Statistical correlation analysis.

Mathematical proofs are not more rigorous than science?

Dear, <>

Mathematics and science are both rigorous subjects, but they differ in their degree of rigor.

The rigor of mathematical proofs is higher than that of science, because mathematical proofs rely on logical reasoning and precise definitions of mathematical symbols, rather than on experimental data or empirical observations. No.

Summary. Hello dear, glad to answer for you! <>

Scientific theories can be derived through both experiments and observationsTheories are derived through experiments. This method relies on experimental research and verification under artificial control conditions, and draws theoretical conclusions through experimental data and results.

For example, Albert Einstein deduced the quantum theory of light through experiments with the photoelectric effect. This is one of the important ways in which scientific theories are derived. The advantage is that the variables can be isolated experimentally, and the reliability and accuracy of the theory can be rigorously tested.

The disadvantage is that the artificiality and limitations of the experiment may affect the generalizability of the theory. 2.Theories are derived from observation.

This method relies on the observation and study of natural phenomena, and derives theories through the summary and induction of observed data and laws. For example, Darwin's theory of evolution is based on long-term observations of biodiversity and environmental changes in nature. This is also an important way for scientific theories to be derived.

Whether a scientific theory can be derived from both experiments and observations.

3.Solid rubber inspection is combined with observation. Many scientific theories are derived using a combination of experimental and observational methods.

For example, ecological theory requires both experimentation and long-term natural observation. This is the most ideal way to derive the theory, which can make up for the shortcomings of the experimental method and the observation method, and obtain the most comprehensive and accurate theoretical conclusion.

I'm a junior high school student, and I've found that there are a lot of theories in my science books that haven't been experimentally proven, like the structure of molecules and atoms, and I can't see the keys that I can get by looking at them with a microscope. Is that right about me?

Your idea is right to kiss <>

So anyway, the theories in my science books are true, right, and come up with different scientific methods.

Right. That's right, kiss <>

<> Mo. Bius Band Experimental Experiment 1

Draw a line in the middle of a cut piece of paper, stick the circle to form a "Mebius circle", and then cut it along the line to divide the circle in two.

As a result, it was supposed to get two circles, and strangely enough, it turned out to be a large circle after cutting.

A Möbius strip (m bius band) is a one-sided, non-orientable surface.

It is named after the discovery of the Morbius manuscript (August Ferdinand M Bius, 1790-1868).

One end of the rectangular paper ABCD is fixed, and the other end of the DC is twisted for half a week, and the AB and CD are glued together to obtain.

The surface is the Möbius circle, also known as the Möbius belt.

First, the nature is different.

Experimental principle: The theoretical basis on which experimental design is based refers to the existence and motion laws of things obtained through analysis, reasoning, induction, and generalization on the basis of a large number of observations, scientific experiments, and social practice.

Experimental methods: The researcher designs the experiment according to the essence of the research problem, controls the changes of certain environmental factors, makes the experimental environment relatively simple than the reality, and discovers the law through the observation of repeatable experimental phenomena.

Second, the design principles are different.

2) Based on this theory, logical reasoning is carried out and hypothetical propositions are proposed.

3) design research procedures and methods;

Summary. Experimental scientific theories refer to scientific theories that are conducted through experimental methods and put forward based on experimental results. Experimental scientific theories are mainly based on the results and data of scientific experiments, and through inductive and deductive methods, they put forward explanations and theories about the regularity and principle of the natural world.

Experimental science theory is one of the main methods of scientific research, which can help scientists understand the nature of nature, reveal the inner laws of things, and promote the development and progress of science and technology.

Can you add, I don't quite understand it.

Can you add that.

The 100 science experiments and their principles are as follows:

1. Chopsticks Timmy inserts chopsticks into a bottle full of rice and finds that one chopstick can lift the whole bottle of rice, which is caused by the friction between chopsticks and rice and between rice.

2. The white paper ruler is a magical little experiment, the white paper is spread on the edge of the half suspended on the ruler of the desktop, the white paper and the desktop can be regarded as full contact, they have less air between the cherry traces, when the weight hits the ruler, due to the action of the force, the ruler will pick up the white paper, at this time the air pressure between the white paper and the desktop is less than the atmospheric pressure, and the atmospheric pressure will suppress the white paper and not let the ruler bounce up.

3. The bouncing bubbles are prepared into a mixed solution of water and dish soap according to the ratio of 3:1, and the solution is taken with a straw, and the bubbles can be blown out, but the bubbles are easier to break; Mix the glue and the mixed solution in a ratio of 1:2, and then use a straw to take the solution and blow out the bubbles.

Touching the bubble with gloves not only makes it difficult to break, but it also bounces when touched by hand.

Decryption moment: The bubbles in the bubble are explosive due to the evaporation of water, and they will become very sticky after adding glue, and the water will not evaporate easily, and the strength of the bubble film will increase, so it can jump on the back of our hands.
