Are the sun and the solar system to the sun as the center, dominated by its gravity and the objects around it sports posed by the system
. Members include the sun, Mercury, Venus, Earth, Mars, Saturn, Jupiter, Uranus, Neptune, Ming
Wang, more than 2000 asteroids 34 satellites, as well as a lot of comets and meteoroids.
The sun (Sun)
The center of the solar system objects. Are a star. Contains nearly 98% of the solar system quality. With the Earth's average
Distance of 149,600,000 kilometers diameter 1,390,000 kilometers, to the Earth 109 times the volume of the Earth's 1.3 million times, Ping
Are the density of 1.4 grams / cubic centimeter. Surface temperature of about 6000 degrees Celsius, the center temperature of 15 million degrees Celsius. By
Nuclear fission of hydrogen nuclei into helium thermonuclear reaction a large amount of energy. The naked eye we see the surface layer called the "light ball"
, Light balls above a layer called the "chromosphere", the most outer layer called the "corona", which formed the sun's atmosphere. Too
Yang's rotation period is 25 days, the bipolar area is about 35 days, the sun on the most abundant chemical element hydrogen.

The sun's activity stems from its central part. The sun's core pressure of more than 34 billion times the Earth. Here at hair
Health of nuclear fusion. Fusion led to the four proton or a hydrogen atom or helium nuclei阿爾法粒子. Al
Law on the quality of particles smaller than 0.7 percent to four protons, the quality of the remaining energy is transformed into the sun and was released to the table
Noodles, and through the process of emitting light and heat convection. Solar core, through millions of years of energy required to reach
Its surface. Per second have been 700 million tons of hydrogen into helium. In the process, there are about five million tons of net energy
Volume was released, so the sun can make light-emitting.

Photosphere are the chromosphere above. Amount of solar power through the region from the center outward transfer. This layer can be seen too
Yang flares. Flares sunspots are formed before the chromosphere the hydrogen generated by hot clouds. Photosphere at some
Region, a slightly lower temperature than the surrounding (usually 4000 degrees Celsius), this is the sunspot.

The sun's outer atmosphere called the corona. Date the region has t. Date ts are the upper chromosphere at the enormous
Flame. The most coronal extension of outer space-oriented and radiation generated by the particles from the sun. Coronal only have the whole day
Can be seen when fresh.

The sun's age of about 46 million years, it can continue to burn about 50 million years. At the final stage of its existence, too
Yang will be in the helium into heavy elements, the sun will also be the beginning of the volume continues to expand, until the Earth swallowed. At
一億年After the red giant stage, the sun will suddenly collapse into a white dwarf - all stars of the existence
The final stage. Go through several萬億年, it will eventually completely cooled.

Mercury (Mercury)
Ancient China, also known as "辰星." The sun, one of the nine planets. From the sun recently. With solar distance 0.39
Astronomical units, that is 57.91 million kilometers in diameter for 38% of the Earth, mass of the Earth's 5.5%, density of water
5.4 times larger orbit eccentricity, 0.21. Revolution period of 88 days, the rotation period of 59 days. For
The sun side of the temperature of 400 degrees Celsius, while the sun back to -160 degrees Celsius, Mercury has many craters on
And has a strong magnetic field, the surface strength of 1% of the Earth. Shell by the porous soil, or similar surface soil of the moon rock
Composed of stone powder. Mercury is even lower than Jupiter's satellite Ganymede (Ganymede) and Saturn's satellite Titan (soil
Titan) is also small.

Mercury surface similar to the lunar surface. Meteorite st covered the ups and downs撞成hills, a few kilometers of the fault cliff high
Stretching hundreds of kilometers, large and small craters are everywhere. Looks at the sun than the Earth on large two and a half times.
Because of not enough air to scatter sunlight, the sky is usually dark. If you look up to the sky, he also
Xu will find two bright stars: a bright yellow are the Venus, the other one is blue earth.

On observations from the Earth, Mercury and the sun angle of the largest only 28 degrees at dawn or ring the day it appeared in the sky
, So its observation very difficult. In the "sailors" on the 10th visit the Mercury before the awareness of Mercury are
Very small.

Because of its revolution and rotation of the relationship between the more complex, if the sun to rise from the sun for a Down
Units to calculate, on the day of Mercury will be the day the Earth 176.

Mercury appears that it can not exist on the water, its atmosphere is very small, and very high temperatures ring the day. However, in 1991
Mercury at the Arctic scientists found an unusual bright spot. Highlights the possible cause of this are at the surface
Or underground ice. Because the orbit of Mercury is rather special, at its North Pole, the sun is always on the horizon only irresolute
Further. At some of the internal crater may never see the sun because of the temperature dropped to -161 degrees Celsius
. Such a low temperature is likely to solidification from the planetary internal release of gas, or accumulation of ice from space
.

Mercury atmospheric pitiful, its main components for helium (42%), Sodium vapor (42%) and oxygen (15%), and its
The average surface temperature of 179 degrees Celsius, up to 427 degrees Celsius, a minimum of -173 degrees Celsius.

Venus (Venus)
Ancient China, also known as "Venus", "Chang", "Tai", "star" and so on, the nine planets of the solar system
1. According to the order from the sun for the second. With an average distance of the sun 0.72 astronomical units, 108,210,000
Km. Size and the Earth is similar to the diameter of the Earth smaller than 5%, quality 82% of the Earth, the density of water, 5
.2 Times the revolution period of 225 days, the rotation period is 243 days, the rotation direction and the other planets the contrary, the surface cover
Covered a very thick atmosphere, the most carbon dioxide, oxygen and water vapor low surface temperature as high as 480 degrees Celsius
About. Venus surface of the magnetic field only one-thousandth of the Earth also has an ionosphere. Separately in the morning because of Venus
Morning and evening in the sky, the ancient astrologers have been think there are two such planets, then sub -
Do not be referred to as the "Morningstar" and "evening." In English, Venus - "Venus" (Venus) is an ancient Romanian
Horse of the god of love and beauty. It has always been curly clouds shrouded in mystery at.

Because of Venus and the Earth in size, mass, density and weight on very similar, and almost all of Venus and the Earth
Formed simultaneously by the same nebula, astrologers will have them as sister planets. But recently scientists have discovered
, Venus and the Earth in fact very different. Venus has no oceans, it has been the main ingredients for a thick oxide
Carbon in the atmosphere surrounded by water does not. Its cloud is composed of sulfuric acid droplets. At the surface, it
Equivalent to atmospheric pressure at sea level on the Earth 92 times.

Because of Venus's thick atmosphere of carbon dioxide caused by "greenhouse effect", Venus surface temperature up to 482 photo
S degrees. Sunlight through the atmosphere will be hot roast Venus surface. Surface outward radiation of heat at the process by
Atmospheric barrier, can not be distributed into outer space. This makes Venus than in Mercury also hot.

Random surface of Venus is covered with many small craters. Because of Venus's thick atmosphere, a diameter less than 2 kilometers
Crater is almost impossible to retain it. And when a large meteorite in a small pit formed before the meteorite hit the surface of Venus, and its proction
Health and debris at the surface of the crater proced exceptional group. Volcanoes and volcanic activity of a lot of the surface of Venus. To
Less 85% of Venus surface covered with volcanic rocks. Many lava flows hundreds of kilometers, fill the lowland, forming a broad
Wide plains. In addition to hundreds of large volcanoes, more than 100,000 small crater Block embellishment at the surface of Venus. From fire
Mountain emitted lava flows resulted in a long trench, ranging up to hundreds of kilometers, one of a range of ultra -
Over 7000 kilometers.

The topography of Venus is covered with vast lava plains and mountains of geological activities undermine or plateau. At
Maxwell Hill Ishtar region are the highest mountain on Venus. Aphrodite highland region occupies almost
Half of the equatorial regions. Magellan plans to obtain more than 2.5 kilometers of Venus images show the existence of the plateau zone prescribed
Bright soil moist. However, in the Venus surface, liquid water are unlikely to exist, and could not explain the bright plateau
Reasons. There was a presumption that these bright regions may be e to metal compounds. Studies have shown that this
Some metals may be iron sulfide. It can not exist in the plain areas, but at high altitude is possible. These payments
May also be an alien, and it led to the effect is the same, but the concentrations are lower.

The Earth (Earth)
The nine planets of the solar system, according to the order from the sun for the third stars, with the sun's average distance of about 14,960
10,000 kilometers, the volume of around 1,083,200,000,000 cubic kilometers for the equatorial radius is about 6378 kilometers, the radius is extremely 6,3
57 kilometers, a difference of 21 kilometers. The average water density is 5.5 times the revolution period is 365.25 days, the rotation cycle 2
3:56. Revolution of the Earth orbit is an ellipse with the Earth equatorial plane into 23 degrees 26 minutes angle. So generated
The length of the seasons and day and night. Surface has a solid crust. An area of 51,100 km, one of the total marine table
Area of 71%, land is about 29%, surrounded by the atmosphere, nitrogen, oxygen, water vapor and other gas components. Earth
Has a satellite - the moon. Used to distinguish the characteristics of the Earth are on a black background and blue water, brown and green
Land and the large white cloud.

We are the Earth's atmosphere is 78 percent nitrogen, 21% are oxygen, the remaining 1 percent are other ingredients. Flat surface of the Earth
Both the temperature is 15 degrees Celsius, the mean pressure of 101.3 Pa.

The Earth are the only known solar system planets existence of life. Express our planet's rotation and nickel iron lava nuclear
Heart to generate a vast magnetic field, together with the atmosphere to prevent almost all from the sun and other stars
Harmful rays. The Earth's atmosphere for us to block a lot of meteorites, meteorite much at their arrival and before the
Had been burned.

Since the beginning of human space exploration, our own planet there is a greater awareness. The first man-made human beings to
Ball satellite discovered a strong radiation zone, now called the Van Allen radiation belts. The causes are from
Sports Express in the charged particles in the equatorial region of a circular region to capture the Earth's magnetic field. Earth's magnetic field
By the solar wind into a droplet-shaped twist of this phenomenon is also found by satellite. We also found that once we identified
Is very calm for the upper atmosphere, they are very active, and it ring the day and evening to narrow expansion. Live by the sun
Dynamic effects of the Earth's upper atmosphere to affect weather and climate.

Apart from the impact of the Earth's climate, the sun's activities are also our atmosphere for the brilliant performances. When the charged particle
Son of the Earth's magnetic field has been captured, they are with our planet's pole impact air molecules so that these open air molecules
Sending light, this is the "Aurora."

Mars (Mars)
Ancient China, also known as "熒惑," the nine planets of the solar system, according to the order from the sun for the fourth stars. And too
Yang average distance 1.52 astronomical units, or 227,940,000 kilometers in diameter for 53% of the Earth, its size at
Ranked seventh in the solar system. Quality for 11 percent of the Earth, the density of water is 3.9 times the revolution period of 687 days,
Rotation cycle of 24 hours 37 minutes. Mars's equatorial plane and orbital plane 23 degrees 59 minutes into the corner, so on Mars also has
Four Seasons, a quarterly basis and around six months long. Very thin atmosphere, mainly composed of carbon dioxide, the surface temperature at Chek
Road ring the day and the highest, at 28 degrees Celsius, down to -132 degrees Celsius at night, white極冠of the main components of water ice
Also has a small amount of dry ice, the size of極冠changes with the seasons. Sometimes disappear in summer and winter increase. Surface
Comparing the same as the Earth has rocks, volcanic and desert regions. On Mars because of the rock, sand and sky are red
Color or pink, so the planet is often also referred to as the "red planet."

The southern hemisphere of Mars are similar to the moon covered with craters of the ancient plateau, while the Northern Hemisphere, mostly organized by young plains
Composition. Mars 24 kilometers high on the "Olympus" Mountains can be called the solar system are the highest mountains. Away from fire
Stars around tens of thousands of kilometers, have two very small stars, which are the Martian satellites.

In Chinese, the name is reminiscent of Mars to the "fire" and hot, but in fact, this red planet is
Abnormal cold and dry. Nevertheless, Mars is still in the solar system and earth are the most similar to a planet. It
Smaller than the size of the Earth, the atmosphere thinner than the Earth.

A very thin atmosphere of Mars, the Earth's atmospheric pressure is only 7 thousandths. The main components of the atmosphere of Mars are dioxoketene
CFCs, and other ingredients are nitrogen, argon, oxygen and so on. Mars atmospheric water at the proportion of only 0.03%
. Thus abnormal drying the surface of Mars.

Mars the average temperature of minus 55 degrees Celsius, while the larger temperature difference: In the summer, daytime temperatures up to
Twenty degrees Celsius, while in winter the temperature can be as low as minus more than 100 degrees Celsius. Mars often have strong winds,
And thus often leads to large-scale st storms.

Scientists have found that many areas on Mars have been signs of erosion, but it seems to criss-cross the riverbed
Telling us that Mars once had liquid water, they gather into large and small lakes, and even marine
. Scientists, it was explained that at the early formation of Mars, the planet by thick clouds of carbon dioxide
The parcels, resulting in a powerful "greenhouse effect" by the solar radiation, heat the surface of Mars have been obstructing the clouds
Separated, can not be distributed to the outer space, making temperatures rise, so that liquid water to exist. At that time, the warmth of the Martian
Humid, you may have been bred to life.

Mars has two poles at many solid-state carbon dioxide (dry ice), scientists have speculated that in these enormous ice
Cover may exist below the water-solid.

Jupiter (Jupiter)
Ancient China, also known as "歲星," one of the solar system planets. According to the order from the sun for the Fifth stars. And too
Yang average distance of 5.20 astronomical units, or 778,300,000 kilometers. Volume and quality than the other eight planets
Combined, and the equatorial diameter of the Earth 11.18 times for the 142.8 thousand kilometers. The quality of the Earth's 317.89-fold
, Density of water 1.3 times, public transfer cycle 11.86, the rotation cycle for the 9:50 is the fastest one rotation
Stars, so the shape is very flat. Jupiter atmospheric shading shows staggered parallel to the equator of the cloud band, the temperature was about -12
1 degrees Celsius. Well-known Great Red Spot are embedded in the cloud band of clouds. Atmospheric thickness of about 730 kilometers. Atmospheric depths have
Water vapor, but the total amount of less than hydrogen. There are acetylene, ethane and phosphine. Jupiter's magnetosphere has been a huge package
Around with the Earth's magnetosphere similar to, but charged particles within the magnetosphere the energy of the radiation of the Earth is about one million times. Wood
Stars than the Earth magnetic field strong 20-40 times, suggesting that Jupiter has its own energy. Jupiter has 13 satellites, consider someone
There may be satellites fourteenth. There is a halo of Jupiter and Aurora

地球為什麼是圓的?
Why the Earth Is Round
地球是太陽系從內到外的第三顆行星,也是太陽系中直徑、質量和密度最大的類地行星。它也經常被稱作世界。英語的地球Earth一詞來自於古英語及日耳曼語。地球已有44~46億歲,有一顆天然衛星月球圍繞著地球以27.32天的周期旋轉,而地球以近24小時的周期自轉並且以一年的周期繞太陽公轉。迪士尼有同名紀錄片。

Our never-thought to ask question for today is: Why is the earth round? Why not a cube? A cube? No,that's silly. Is it? Why?Because…,because really big things like to be round for some reason. Exactly right.And that reason is gravity.

Think of it this way. Suppose the earth were a cube. Then some points on its surface would be farther away from the center than others. The corners, for example, would be much farther out than the rest.

Since gravity works equally on everything, there would be a tendency to pull those uneven places down. The surface would even itself out. The only geometrical object in which every point on the surface is the same distance from the center is a sphere.

But wait a minute,I've seen pictures of asteroids that have all sorts of crazy shapes.Why aren't they round?Only because they aren』t big enough for gravity to be a determining factor. If an asteroid were to suddenly become as big as a moon, it would indeed rearrange itself graally into a sphere.

今天,我們「從未想過的問題」是:地球為什麼是圓的?為什麼不是方形的?方形?那太可笑了。是嗎?為什麼?因為……因為非常大的東西通常都是圓的。完全正確。這個原因就是重力。

我們這樣想,假設地球是一個立方體。而地球表面的某些端點離中間或其它端點比較遠。比如,立方體的各個角離得很遠。

由於重力對所有物質的作用是相等的,因此不均勻的地方會被向下拉。表面使其本身變得平均。唯一一個表面上的每個角到中心距離都相等的幾何物體就是球體。

等一下,我看過很多行星的圖片,它們都是奇形怪狀的。它們為什麼不是圓的?

那隻是因為行星太小,重力不能成為其決定因素。如果行星突然變得和月亮一樣大,它就會真正重新安排逐漸變成一個球體。

Does Technology Prevent Creativity?

Thanks to Lowell Monke, I am getting rather critical about tools and technology supporting creativity. In many cases technology distracts our concentration, causes problems to our social network and interferes with our natural rhythm of life. Monke's "Breaking Down the Digital Walls" is an interesting book and I am looking forward to read the forthcoming book. In the meanwhile, please take a look at his thought-provoking article "The Human Touch" . Just to give you an example of Monke's thinking: "What 'Information Age' values tempt us to forget is that all of the information gushing through our electronic networks is abstract; that is, it is all representations, one or more symbolic steps removed from any concrete object or personal experience".

Another wake-up call came, when I read an interesting report from National Science Foundation (NSF) workshop about Creativity Support Tools. There were some guidelines for these Creativity Support Tools introced . To me they are like from an HCI manual and similar to Shneiderman's "Leonardo's Laptop: Human Needs and the New Computing Technologies" - you remember those 4-phases: Collect - Relate - Create - Donate.

What bothers me is the concept "Social Creativity" described the report. This concept and the related research is to me very inconsistent, it is mostly based on communities-of-practice research, not creativity research. I noticed it already when I participated a social creativity session in the HCI International (UAHCI) conference in Las Vegas.

The Internet is a giant network of computers located all over the world that communicate with each other. The Internet is an international collection of computer networks` that all understand a standard system of addresses and commands, connected together through backbone systems. It was started in 1969, when the U.S. Department of Defence established a nationwide network to connect a handful of universities and contractors. The original idea was to increase computing capacity that could be shared by users in many locations and to find out what it would take for computer networks to survive a nuclear war or other disaster by providing multiple path between users. People on the ARPNET (as this nationwide network was originally called) quickly discovered that they could exchange messages and conct electronic "conferences" with distant colleagues for purposes that had nothing to do with the military instrial complex. If somebody else had something interesting stored on their computer, it was a simple matter to obtain a (assuming the owner did not protect it). Over the years, additional networks joined which added access to more and more computers. The first international connections, to Norway and England, were added in 1973. Today thousands of networks and millions of computers are connected to the Internet. It is growing so quickly that nobody can say exactly how many users "On the Net". The Internet is the largest repository of information which can provide very very large network [參考譯文] Internet是由位於世界各地相互通信的計算機連接而成的巨大的計算機網路。 Internet是計算機網路的國際性的集合,這些網路都符合具有地址和命令的標准體系,並經骨幹網連在一起。Internet始建於1969年,當時美國國防部為連接少數幾所大學和協議企業而建立了一個全國性網路。最初的想法是要增加計算機能力並可由許多地點的用戶共享,並且通過提供用戶間多條路徑來找到哪一種計算機網路能夠在核戰或其他災難中倖存。ARPNET(這種全國網路最初的名稱)上的用戶很快就發現他們可以與遠距離的同事交換消息,並且進行某種目的的電子「會議」,而這些目的與軍事工業企業沒有任何關系。如果另外一些人在其計算機中存有有趣的東西,得到其拷貝是很容易的事(假定擁有者沒有進行保護)。 幾年間,新的網路接入使越來越多的計算機加入進來。在1973年進行了第一次與挪威和英國的國際連接。今天,有成千上萬的計算機網路和數百萬台計算機與Internet相連。Internet發展如此之快以至於沒有人能准確地說出網上有多少用戶。 Internet是最大的信息寶庫,它可以提供非常巨大的網路資源。這種網路資源可分為網路設備資源和網路信息資源。網路設備資源使我們能夠進行遠程計算和通信。網路信息資源向我們提供各種各樣的信息服務,如科學、教育、商務、歷史、法律、藝術和娛樂等等。

6. 求一篇一百字左右的英語科普文,越簡單越好,是科普類型就好,初中、小學水平都可以,及翻譯

PUBLIC ATTITUDES TOWARD SCIENCE
Anyway, even if one wanted to, one couldn't put the clock back to an earlier age. Knowledge and techniques can't just be forgotten. Nor can one prevent further advances in the future. Even if all government money for research were cut off (and the present government is doing its best), the force of competition would still bring about advances in technology. Moreover, one cannot stop inquiring minds from thinking about basic science, whether or not they are paid for it. The only way to prevent further developments would be a global state that suppressed anything new, and human initiative and inventiveness are such that even this wouldn't succeed. All it would do is slow down the rate of change.
