Space Shuttle Information: Golden Pen)

The space shuttle is a winged, reusable rocket-powered spacecraft. It was launched from the atmosphere by an auxiliary launch vehicle as a means of transportation between the earth and outer space. The space shuttle combines the characteristics of an airplane and a spaceship, like a winged spaceship, and looks like an airplane. The wings of the space shuttle provide air braking when returning to Earth and lift when landing. Like other disposable vehicles, the space shuttle ascends vertically by rocket power. The space shuttle has a low payload ratio because of its wings. After more than 20 years of use, it is found that the cost necessary to ensure the reliability of the space shuttle is too high, which is close to elimination.

1. Why do the stars twinkle? (golden pen)

We see the stars shining, not because the luminosity of the stars has changed, but because of the occlusion of the atmosphere.

The atmosphere is between us and the stars. When starlight passes through the atmosphere, it will be affected by the density and thickness of the atmosphere. The atmosphere is not absolutely transparent, and its transparency will change according to its density. So when we look at the stars through it on the ground, we will see that the stars seem to be flashing. (Black pen)

Why do people yawn? (golden pen)

When we feel tired, a lot of carbon dioxide has been produced in our bodies. When there is too much carbon dioxide, oxygen must be supplemented to balance the needs of the body. Because these residual carbon dioxide will affect our body's functional activities, then the body will send out a protective reaction, so we yawn. Yawning is a deep breathing action, which will let us breathe in more oxygen and expel more carbon dioxide than usual, and also can eliminate fatigue. (Black pen)

The third board:

Total solar eclipse:

Total solar eclipse is a kind of solar eclipse, that is, the astronomical phenomenon that the sun is completely covered by the moon. If the sun, the moon and the earth are in a straight line, the moon blocks the sunlight that hits the earth, and the shadow behind the moon just falls on the earth, then a solar eclipse occurs. People in the shadow of the moon on the earth began to see the sun gradually weakening, and the sun was covered by a circular shadow. When the sky is dark and completely covered, the brightest stars and planets can be seen in the sky. After a few minutes, the sun gradually emerged from the shadow edge of the moon and began to shine and make the last contact. Because the moon is smaller than the earth, only people in the shadow of the moon can see the total solar eclipse.

Fun Technology (Golden Pen)

Once, Newton was so absorbed in doing experiments in the laboratory that he forgot the time for eating. His assistant took some eggs and sent them to the laboratory. He said to Newton, "Here are some eggs. Do it yourself. " Newton said, "OK, thank you. Please put the eggs there. " After that, he immersed himself in the experiment.

After a long time, Newton was hungry and remembered that he hadn't had lunch yet. So, he took a small pot, put the eggs in the pot, put them on the stove, and began to do experiments again.

Half an hour later, Newton finished the experiment. At this moment, he remembered the eggs in the pot. He opened the lid and found there were no eggs in it, only a pocket watch.

Newton was surprised and looked up. The eggs are still on the table, but the pocket watch on the table is missing. It turned out that Newton was absorbed in the experiment and cooked the pocket watch as an egg. (Black pen)

Why can't ostriches fly?

A giant ostrich, but they can't fly into the sky! This is not because their wings are useless, but because their feathers are too soft and their wings are too small to fly at all. In addition, the ostrich's muscles are underdeveloped and its sternum is flat, which is not conducive to flying.

Scientific and technological knowledge manuscripts are simple in content.

What are the three parts of sunlight? Among the eight planets, Jupiter is the largest freshwater lake in China and the first of the five mountains in Poyang Lake. The rotation of Mount Tai is around the earth axis passing through the north and south poles, and the direction is from west to east. The farther away from the poles, the greater the speed. The largest mammal in the world is the blue whale. Which city is called the foggy capital of the world, London? What is the main energy of 2 1 century? What kind of pollution is called windmill power generation kingdom in Denmark? What kind of pollution is called the world's number one killer? The nearest planet to the sun is the Mercury Green Mud Observatory. In which country is Britain's dry ice carbon dioxide? Bi Sheng of the Northern Song Dynasty in China invented the mousetrap. Why does printing say that China is a land power and a maritime power? With a vast territory of 9.6 million square kilometers, China is the largest country in Asia and one of the largest countries in the world, ranking third in the world after Russian and Canadian countries. The coastline of Chinese mainland starts from the mouth of Yalu River in the north and reaches the mouth of Beilun River in the south, reaching more than18,000 kilometers, plus the island coastline. There are more than 6,500 islands; According to the relevant provisions of the United Nations Convention on the Law of the Sea and China's proposition, the sea area under the jurisdiction of China is about 3 million square kilometers. China has a vast sea area and rich resources, so China is also a maritime power. Why is space junk so harmful? They have become potential killers of satellites and orbiting space stations, seriously threatening the safety of astronauts. You know, space junk runs at the speed of the universe. An oncoming metal particle with a diameter of 0.5 mm is enough to pierce a sealed flight. Dust that people can't distinguish with the naked eye (such as paint chips and paint powder) can also kill astronauts; A fragment as big as an aspirin pill can paralyze a satellite and send a spacecraft costing hundreds of millions of dollars to a dead end. Slightly larger space debris will damage the surface materials of spacecraft, cause impact pits and damage surface devices; The high-speed impact of space debris will vaporize itself and the surface material of the spacecraft being hit into plasma clouds, which will eventually lead to the failure of the spacecraft.

Who knows how the sea freezes? Everyone thinks that sea water has salt. In fact, after the temperature drops, the solubility of water will also decrease, that is, salt will precipitate. In this way, water will freeze. Who knows if Altair has it now? What we are seeing now is the "light" it gave off a long time ago. As for whether it exists now, only people in the Altair galaxy know that the light we observe from the earth is still the light emitted by a stable star. Moreover, the life span of stars is over 6 billion years, so Altair should still exist now.

1, mathematical motto: 1, mathematics is an infinite science. (Will) 2. The problem is the heart of mathematics. -p.r.halmos) 3. As long as a branch of science can ask a lot of questions, it is full of vitality. No problem, indicating the termination or decline of independent development. -Hilbert) 4. Some beautiful theorems in mathematics have such characteristics: they are easy to be summed up from facts, but the proofs are extremely profound. -Gauss) 5. Mathematics is the queen of science, while number theory is the queen of mathematics-Gauss) 6. The ancient Greek philosopher Zhi Nuo claimed. He has four mathematical paradoxes that have been passed down to this day. He once said a famous saying: "The big circle has a little more knowledge than the small circle, but because the circumference of the big circle is longer than that of the small circle, its contact surface with the outside world is larger than that of the small circle, so it feels more lack of knowledge and needs to study hard." 7. Learn mathematics as a language and learn the usage of each term. Be familiar with the meaning of each symbol. 8. Don't let go of any seemingly simple examples-they are often not that simple or can lead to many knowledge points. 9. Just because you can use mathematical formulas doesn't mean you can learn mathematics. 10. If you are not a genius, you can't play games if you want to learn math-you think you have done it, but your math level has not improved with your ability to pass the customs. 2. Math story: When Gauss was in elementary school, once after the teacher taught addition, because the teacher wanted to have a rest, he came up with a topic for the students to calculate and have a look. The title is: 1+2+3+. +97+98+99+ 100 = The teacher is thinking that the children must have finished class now. I used this as an excuse to go out, but Gauss stopped me! It turns out that Gauss has worked it out. Little friend, do you know how he did it? Gauss told us how he worked it out: add 1 to 100, and add 100 to 1, adding two lines. That is: 1+2+3+4+. +96+97+98+99+100/00+99+98+97+96+.+4+3+2+1=1+. 3. Mathematical problems: (1) Add appropriate operation symbols between the numbers of the following problems. 1() 2 () 3 () 4 =1() 2 () 3 () 5 =165448.7 =11() 2 () 1+2+3+4+5+6+7+8+9 = 44 1+2+3+4+5+6+7+8+9 = 50 1+2+3+4+5.

What is the content of sci-tech handwritten newspaper?

Hua is one of the main mathematicians in number theory.

But he would rather start a new stove and leave number theory to study algebra and complex analysis that he is not familiar with. As early as 1940s, he proposed that "genius lies in accumulation, and cleverness lies in diligence".

Although Hua is brilliant, he never mentions his talent. Instead, he regards "diligence" and "accumulation", which are much more important than cleverness, as the key to success, and repeatedly educates young people to learn mathematics so that they can exercise themselves at any time. In the mid-1950s, Hua proposed: "There should be speed and acceleration." The so-called "speed" means producing results, and the so-called "acceleration" means constantly improving the quality of results.

1978, he earnestly put forward at the Chengdu conference in chinese mathematical society: "Early publication, late evaluation." Later, it was further put forward: "Efforts are in me, and evaluation is in people."

This actually puts forward the objective law of scientific development and scientific work evaluation, that is, scientific work can gradually determine its true value after historical test, which is an objective law that is independent of human subjective will. "In the 1950s, in the preface of Introduction to Number Theory, Hua compared mathematics to playing chess, and called on everyone to find a master, that is, to compete with great mathematicians.

There is a rule in China chess, that is, "Don't tell a true gentleman when watching chess, and don't regret a gentleman." Hua pointed out in a speech in Huainan Coal Mine in 2008+09865438: "Look at chess without saying a word, help each other;" I regret the gentleman and change my shortcomings. " 1979 when he was in England, he pointed out: "The village is old and easy to empty, and people are old and easy to disperse. The scientific approach is to abstain from empty and scattered. I am willing to stick to it all my life. "

Einstein is an epoch-making great scientist, the pioneer and founder of modern physics. 1March 879 14 was born in Ulm, Germany, and spent his youth in Switzerland.

1900 graduated from Zurich University of Technology. Unemployment after graduation.

After two years of hard work, I found a permanent job in the patent office in Bern. His early series of historic contributions were all completed here.

1909 began to teach in universities. 19 14 was invited to return to Germany as the director of the Royal William Institute of Physics and a professor at the University of Berlin. 1933 when Hitler came to power, Einstein was persecuted for the first time because he was a Jew and resolutely defended democracy, and was forced to move to Princeton, USA.

1940 American citizenship. 1955 April 18 died in Princeton.

One of Einstein's pioneering contributions is the development of quantum theory, and his iconic career is his theory of relativity. In his paper entitled "On Electrodynamics of Moving Objects" published in 1905, he put forward the special theory of relativity completely.

After the establishment of special relativity, Einstein began to devote himself to the study of gravity theory. Einstein's cosmology has a great influence on astronomy.

19 17, Einstein published his first paper on the universe, Cosmological Investigation Based on General Relativity, which announced the birth of relativity. He once said: "Scientific research can dispel superstition because it encourages people to think and observe things according to causality."

His study of cosmology embodies this spirit of opposing superstition. 1. Why do the stars twinkle? We see the stars shining, not because the luminosity of the stars has changed, but because of the occlusion of the atmosphere.

The atmosphere is between us and the stars. When starlight passes through the atmosphere, it will be affected by the density and thickness of the atmosphere. The atmosphere is not absolutely transparent, and its transparency will change according to its density.

So when we look at the stars through it on the ground, we will see that the stars seem to be flashing. 2. Why do people yawn? When we feel tired, a lot of carbon dioxide has been produced in our bodies.

When there is too much carbon dioxide, oxygen must be supplemented to balance the needs of the body. Because these residual carbon dioxide will affect our body's functional activities, then the body will send out a protective reaction, so we yawn.

Yawning is a deep breathing action, which will let us breathe in more oxygen and expel more carbon dioxide than usual, and also can eliminate fatigue. 3. Why can snakes walk without feet? Snakes have many scales, which are the outermost armor on their bodies.

Scales are not only used to protect the body, but also to be their "feet". When a snake crawls forward, its body will be S-shaped.

Every scale outside the S-shape will tilt upward to help the snake catch the uneven road when it moves forward. These scales cooperate with the muscles of the snake and can push the body forward, so the snake can walk without feet! 4. Why do sunflowers always bloom towards the sun? There is a substance called "auxin" in the stem under the sunflower disk.

This substance has the function of accelerating replication, but it is anti-optical, and it will run to the backlight side whenever it encounters light. So when the sun rises, the stem of the sunflower immediately hides to the side of the backlight, as if the whole plant is bent in the direction of the sun.

5. Why does hair turn white when people are old? There is a substance called melanin in our hair. The more melanin, the darker our hair will be. Without melanin, hair will turn yellow or white.

When human beings reach old age, various functions of the body will gradually decline, and the formation of pigments will be less and less, so the hair will gradually turn white! 6. Why do fireflies glow? Fireflies emit light because there is a luminous body at the end of their abdomen, which is filled with a lot of phosphorus-containing luminescent substances and luminescent enzymes, so that fireflies can emit flashing light. The purpose of fireflies is not only lighting, but also courtship, vigilance and trapping.

This is also a communication tool for them. Different kinds of fireflies emit light in different ways, frequencies and colors, so they can convey different information. 7. Why do you growl when you are hungry? When you are hungry, you will purr. This is because the food you have eaten before has almost been digested. Although the stomach is empty, the gastric juice in the stomach will continue to secrete.

At this time, the contraction of the stomach will gradually expand, and the liquid and gas inside will be stirred up and purr. Don't be embarrassed by your stomach growling next time! Because this is a normal physiological action.

8. Why can't ostriches fly? A giant ostrich, but they can't fly into the sky! This is not because their wings are useless, but.

Content of primary school students' scientific and technological manuscripts

With the rapid development of modern science and technology, we have stepped out of the previous era of eating raw food and drinking blood and come to an era of advanced technology.

The development of science and technology has brought great convenience to our life. I used to worry that there would be no lights at night, but every household is brightly lit tonight; It used to be luxurious to taste the delicious food in the sea, but now fish and shrimp are commonplace; In the past, I always found it difficult to deliver letters from home, but now, heaven is still our neighbor ... yes, a series of benefits brought by science can not be ignored! In the Tang Dynasty, Yang Guifei wanted to eat fresh litchi, but fresh litchi could only be eaten in the south, so the emperor sent someone to transport it from thousands of miles away with a fast horse. How many fast horses have been exhausted to ensure freshness! But nowadays, it is common for ordinary people to eat fresh litchi everywhere in the market.

It can be seen that the development of science and technology has brought us much convenience! In ancient times, homeless people missed their relatives in their hometown very much because they lived and worked far away from their hometown for a long time. After writing home letters, their families didn't reply ... why? Because the letter may have been lost halfway before it was delivered home; It is also possible that it took a long time for the family to receive the letter, and it may take a month or two for the wanderer to receive the reply from the family. So it is difficult to say a word to his distant relatives. Now, you can send messages to your family far away, which is very fast. In less than a second, the other person can know what you want to say, not only the conversation, but also the video chat. In this way, you can chat with distant relatives at any time and see what they look like. How happy it would be if you ever met your relatives in the distance! Technology can help you solve things that people can't. For example, if you encounter difficulties in learning, as long as you turn on the computer to type, the correct sentence will be displayed on the computer display screen.

As long as there is science, there is no need to worry about any major difficulties. However, with the development of science and technology, environmental problems have been ignored.

Discharging wastewater into rivers on a large scale makes people unable to eat safe seafood and wastes valuable resources on a large scale, but never thought about how serious the consequences will be. While developing science and technology, we should also protect the environment.

Science and technology is a double-edged sword, which is the driving force of our human progress. It has brought us convenience and development, but it has also brought many negative effects. We should make full use of the benefits brought by science and technology, and we can't ignore the environment on which we live.
