9. The wings of science fly the dream of science.

10. Decorate life with innovation and integrate science and technology into ideals.

Science and technology related knowledge:

In society, it is customary to associate science and technology together, collectively referred to as "science and technology". In fact, the two are closely related, but also have important differences. Solve theoretical problems scientifically, and solve practical problems with technology.

The problem to be solved by science is to discover the relationship between conclusive facts and phenomena in nature, and to establish theories to connect facts and phenomena. The royal task of technology is to apply the results of science to practical problems.

Science is primarily dealing with uncharted territory, and its progress, especially major breakthroughs, is difficult to predict; Technology is working in a relatively mature field and can make more accurate planning.

The essence of science and technology: the discovery or development of the connection between things, through which various substances form a specific system to achieve a specific function.

1.Tradition holds that science is a system of knowledge about nature, society, and thinking that has been accumulated by human beings.

2.By "science" we mean the natural sciences that study natural phenomena and their laws; Technology generally refers to a variety of tools, equipment, technologies and process systems that are synergistically composed of practical experience based on the principles of natural sciences for a certain purpose, but does not include the technical content corresponding to social sciences.

3.Science and technology are a dialectical unity, technology proposes topics, science completes topics, science is discovery, and is the theoretical guidance of technology; Technology is an invention and a practical application of fighting science.

Why can't we run out of oxygen on Earth?

The survival of animals and plants on the earth is inseparable from oxygen, and the combustion of all substances, the decay of animals and plants, and the rust of iron are also inseparable from oxygen. So, will the planet run out of oxygen in the long run?

In the 19th century, the English physicist Thomson? Kelvin once said with great concern: "With the development of industry and the increase of population, in 500 years, all the oxygen on the earth will be used up, and mankind will tend to perish!"

It turns out that this concern is completely unnecessary, and the planet will not run out of oxygen.

The Swiss scientist Schénibel once did such an experiment: he collected the green leaves of many plants, soaked them in water, and put them in the sun. The leaves soon began to emit small bubbles, which were collected by Schénipeb in a test tube.

What are these gases? When Xeniber threw a lit piece of wood into the test tube, the stick burned violently, shooting out a dazzling light. This means that there is oxygen in the test tube, because only oxygen can help with combustion.

Xeniber then introduced carbon dioxide into the water.

He found that the more carbon dioxide that was put in, the more oxygen the green leaves were expelling. Scheberney concluded: "Under the influence of sunlight, plants excrete oxygen through carbon dioxide nutrition. ”

Why do cacti have thorns and leaves?

In order to adapt to the arid and rainless desert environment, over the years, the cactus constantly changes its form, and the leaves gradually disappear and become root thorns or dense hairs to minimize water transpiration. The leaves of the cactus degenerate and rely on the stem for nutrients, while the stem is green and performs the function of the leaf, photosynthesizing in the sun. Therefore, the spines of the cactus are made from the leaves.

Why do frogs blink when they swallow?

Frogs are an expert at preying on insects. It squatted on the edge of the pond, motionless, and stared intently at the various small insects flying in its face, and did not move. Suddenly, the frog leaped up like an arrow off the string, and rolled its whip-like tongue out of its mouth, and ate the worm into its mouth, and hit it with a hundred shots.

What's even more interesting is that the frog blinks every time it swallows food; The larger the food you swallow, the more you blink until you have swallowed it all. What is the reason for this?

The frog has a wide one. With a large mouth, it uses its long tongue to stick to the flying insects and then puts them in its mouth. Frogs have no teeth and can only "swallow dates" and swallow the whole food.

It has no bones at the base of its orbit, and is separated only by a thin membrane between its eyeball and its mouth. Every time you swallow food, the frog's eye muscles contract, producing this blinking motion; At the same time, the eyeballs protrude towards the mouth, creating a pressure that pushes food into the esophagus. In this way, the frog often blinks whenever it swallows.

Four Great Inventions: Gunpowder, Papermaking, Compass and Printing!!

1. Porcelain. 7,800 years ago, the ancestors of the Weishui and Jingshui basins in the northwest were able to fire red and gray ceramic utensils of various shapes.

2. Solar energy utilization. More than 3,000 years ago, China had the development and utilization technology of solar energy.

3. Casting. In ancient times, China has used three major casting methods and technologies, such as mud irrigation, iron irrigation, and wax irrigation.

Fourth, the discovery of oxygen. In the ancient alchemy of our country, oxygen has been discovered.

5. Physics Laboratory. In ancient China, there was an acoustic and vibration laboratory, which was the earliest physical laboratory in the world.

Sixth, the light source. As early as 250 A.D., China was already able to make copper lamps that could change and adjust their brightness.

7. Thermometer. The balance thermometer invented in the Western Han Dynasty was more than 1,600 years earlier than that in Europe.

8. Gyroscope. As early as the Eastern Han Dynasty, gyroscopes were used for navigation, more than 1,300 years earlier than those in Europe.

9. Clocks and watches. It was invented by Zhang Heng of the Eastern Han Dynasty and was the earliest in the world.

10. Drilling technology. In the 11th century, the Northern Song Dynasty created a deep hole drilling technology that drilled more than 200 meters.

How did the sound come about?

The vibration of an object when it collides with an object is a sound.
