题目为《无语》,却说了这么多!

For certain ridiculous reasons, I was oddly recommended as a candidate for a street deputy to NPC by my classmates. I did take the election thing seriously, though I really had no passion and attention to the Chinese politics thing. So, of course, I spoke out against this impropriety at the very moment. How could I act like a stupid clown to pay my fellows’ stupid debt?

All that is now focused on China is her economic boom, which is certainly without doubt. Anyway, are we us human beings an only material spices that are merely running closely for simple foods, clothes, dwellings, and so forth?

In terms of a long term development, the very reform is definitely supposed to take place in the whole national system, political structure and civil policies included.

The society’s orientation seems to have got altered, leading us into a blind alley. Nobody care what is happening or will happening to our country, rather barely about themselves, about their private living conditions. This is the product of our current times.

I am not likely to talk much about the macro thing; otherwise, I shall be playing another stupid role as a rouser, who attempts to wake the deeply sleeping crowd. As a matter of factor, every elite have a clear sense of the real life; maybe they would like not to make a change, just enjoying a current comfortable life; maybe they attempted, but failed to achieve those they had settled; or maybe, somebody are gathered to do something. Who knows?

A intelligent man, an ordinary man and an empty-headed man, who has the happiest life?

Moulin Rouge

since young, i have been showing great fascination with musicals. cos they are filled with wonderful tones and notes, which can always give me a temporary break from the annoyingly complex reality. so, i absolutely agree with Schopenhauer at this point.
i finished seeing the movie Moulin Rouge just a few minutes ago. this is a film that i had been long looking forwars to. seeing as i saw its chinese version Perhaps Love, in my humble opinion, this piece is still beyond my anticipation and made me feel in the very wanted way.
a bourgeois young writer with his only typewriter, and a definitely beautiful and sexy courtesan. once chemical love took place between them, all went in an ideal way until the necessarily tragic end.
the very line that best impressed me is Come what may, i will love you till the dying day.

in company

    电视里的选秀节目很多,琳琅满目。自己年龄越长,关注得越少。现在正在看“快乐成双”的网络直播,觉得挺有意思的,开始幻想假如自己也是一对双胞胎中的一个。。。。。。
    看到有人被淘汰,有些难受。

a wonderfull photo above us

This Hubble image of the Antennae galaxies is the sharpest yet of this merging pair of galaxies. As the two galaxies smash together, billions of stars are born, mostly in groups and clusters of stars. The brightest and most compact of these are called super star clusters. (NASA, ESA/Hubble, and B. Whitmore - Space Telescope Science Institute/Handout/Reuters)
 
i am interested in those amazing objects in space, maybe this is due to its unkowness or uncertainty.
to be an explorer is a thing out of curiosity and challenge.

scientist NIKOLA TESLA

 I respect this giant, who had long been ignored in general views.

Tesla was born "at the stroke of midnight" with lightning striking during a summer storm. He was born in Smiljani near Gospić Lika, (the Krajina, a military district of Austro-Hungarian Empire, now in Croatia). The midwife commented, "He'll be a child of the storm," to which his mother replied, "No, of light." Tesla was baptised in the Old Slavonic Church rite. His Baptism Certificate reports that he was born on June 28 (Julian calendar; July 10 in the Gregorian calendar), and christened by the Serb orthodox priest, Toma Oklobd'ija.

His Serb father, Reverend Milutin Tesla, was a priest in the Orthodox Metropolitanate of Karlovci which gathered to Serbs of the "Greek-rite" as they were legally referred to in Austria-Hungary at the time. His mother, Djuka Mandic, from a prominent Serb family of the Banija, made home craft tools. He was one of five children, having one brother and three sisters. His godfather, Jovan Drenovac, was a Captain in the Krajina army. His family moved to Gospi?in 1862. Tesla went to school in Karlovac (Austria-Hungary), then studied electrical engineering at the Austria Politechnic in Graz, Austria (1875). While there, he studied the uses of alternating current. He also developed a telephone repeater (or amplifier).

In 1881 he moved to Budapest to work for the telegraph company, American Telephone Company. On the opening of the telephone exchange in Budapest, 1881, Tesla became the chief electrician to the telephone company, later engineer to the Yugoslav government and the country's first telephone system. Tesla invented a precursor to modern wireless telephone, known as a telephone repeater (or sometimes a amplifier). The device could act as a audio speaker (not a audio transducer). The device had its resonance tuned to a particular frequency of other repeaters to communicate between each. In 1916, Tesla described the prior developed audio transducers. According to Tesla, it was the "... [S]implest ways [to detect the radiant energy ...] the low frequency gave audible notes. [... in a field, there was] placed a conductor, a wire or a coil, and then Tesla would get a note [...] characteristics of the audible note". The audible sounds were of the quality of the telephones diaphragms of that period of time. The invention was never patented nor released publicly (till years later by Tesla himself). The device also contained the characteristics of modern wireless telephones.

For a while he stayed in Maribor. He was employed at his first job as an assistant engineer. Tesla suffered a nervous breakdown during this time. In 1882 he moved to Paris to work as an engineer for the Continental Edison Company. He worked designing improvements to electric equipment. In the same year, Tesla conceived of the induction motor and began developing various devices that use rotating magnetic fields (for which he received patents in 1888). Tesla visualized the rotating fields and thereby designed the induction motor. Tesla hastened from Paris to his mother's side as she lay dying, arriving hours before her death in 1882. Her last words were to him were, "You've arrived, Nidzo, my pride." After her death, Tesla fell ill. He spent two to three weeks recuperating in Gospi?and Tomingaj. All his life, Tesla kept a home-spun embroidered travel bag from his mother.
Middle years
In 1884, leaving the warfare of his birthplace behind, Tesla moved to the United States of America to accept a job with the Edison Company in New York City. He arrived in the US with 4 cents to his name, a book of poetry, and a letter of recommendation (from Charles Batchelor, his manager in his previous job).

Early employment
Tesla worked for Thomas Edison for a time. Edison offered him $50,000 for improvements in Edison's DC dynamos. Tesla worked nearly a year to redesign the inferior construction. Upon returning to Edison and inquiring about the $50,000, Edison replied, "Tesla, you don't understand our American humor." Tesla resigned. In 1886, Tesla formed his own company, Tesla Electric Light & Manufacturing. The initial financial investors disagreed with Tesla on his plan for an alternating current motor and eventually relieved Tesla of his duties at the company. Tesla was unemployed for a time.

Tesla worked on a New York street gang, as a laborer, from 1886 to 1887 to raise capital to eat and for his next project. In 1887, he constructed the initial brushless alternate-current induction motor. He demonstrated the brushless two-phase one-fifth horsepower (150 W) induction motor to the American Institute of Electrical Engineers (now IEEE) in 1888. Also in 1888, he developed the principles of his Tesla coil. In the same period, he began working with Westinghouse, Westinghouse's Pittsburgh labs. Westinghouse listened to Tesla's ideas for polyphase systems. These systems would allow alternating current [AC] electricity to be transmitted over large distances.
X-rays and friendships
In April 1887, Tesla began investigating what would later be called X-rays using his own devices as well as Crookes tubes. He did this by experimenting with high voltages and vacuum tubes. His technical publications indicate that he invented and developed a special single-electrode X-ray tube. Tesla's tubes differed from other X-ray tubes in that they had no target electrode. He stated these facts in his 1897 X-ray lecture before the New York Academy of Sciences. The modern term for this is the bremsstrahlung process, in which a high-energy secondary X-ray emission is produced when charged particles (such as electrons) pass through matter.

In 1891, Tesla became a naturalized American citizen. Also in this year, Tesla established his Houston Street laboratory in New York. He lit vacuum tubes wirelessly in the lab, providing evidence for the potential of wireless power transmission. Around this time, Tesla developed a close and lasting friendship with author and humorist Mark Twain. They spent quite a bit of time together in Tesla's lab and other areas. Tesla's closest friends were writers and artists. Tesla's also befriended R. A. Jonson, who adapted several poems of the Serbian poet Jovan Jovanovi?Zmaj (and which were translated into English by Tesla).

When he was 36 years old, the first patents concerning the polyphase power system were granted. He continued researching rotating magnetic field principles and polyphase power distribution. By 1892, Tesla became aware of certain characteristics later identified by Wilhelm Conrad Röntgen as effects of X-rays. He performed several experiments (including taking photographs of the bones of his hand) but did not make his findings widely known. Much of his research was lost in the 1895 Houston Street lab fire. He did obtain pictures of the human body with X-rays and subsequently sent the images to Röntgen. His later X-ray experimentation by vacuum high field emissions led him to alert the scientific community first to the biological hazards associated with X-ray exposure.
Wireless and the AIEE
Tesla served as the Vice-President of AIEE, the American Institute of Electrical Engineers (now part of the IEEE) from 1892 to 1894. From 1893 to 1895, Tesla investigated high frequency alternating currents. He generated one million volts of alternating currents using a conical Tesla coil. He developed the skin effect in circuitry, designed tuned circuits, invented a machine for inducing sleep, cordless gas discharge lamps, and transmitted electromagnetic energy without wires, effectively building the first radio transmitter.

In St. Louis, Missouri, Tesla made the first public demonstration of radio communication in 1893. Addressing the Franklin Institute in Philadelphia, Pennsylvania and the National Electric Light Association, he described and demonstrated in detail the principles of radio communication. The apparatus he used contained all the elements that were incorporated into radio systems before the development of the vacuum tube.
World's Fair Exposition
Main article: World Columbian Exposition
At the 1893 World's Fair, the World Columbian Exposition, in Chicago, Illinois, celebrating the 400th anniversary of Christopher Columbus' first voyage to America, an international exposition was held, in which, for the first time, a building was devoted to electrical exhibits. It was a historic event and the beginning of a revolution as Tesla and Westinghouse introduced visitors to AC power by providing AC energy to illuminate the World Columbian Exposition. The public at large observed firsthand the qualities and abilities of AC power. All the exhibits were from commercial enterprises. Edison, Brush, Western Electric, and Westinghouse all had exhibits. General Electric Company (backed by Edison and J.P. Morgan) proposed to power the electric fair with direct current at the cost of one million dollars.

Westinghouse proposed, armed with Tesla's AC system, to illuminate the exposition for half as much. Tesla's high-frequency high-voltage lighting produced more efficient light with less heat. A two-phase induction motor was driven by current from the main generators to power the system. Edison tried to prevent the use of his light bulbs with Tesla's system. GE banned the use of Edison's lamps in Westinghouse's exhibits. Still, Westinghouse's proposal was chosen over the inferior DC system to power the fair.

Westinghouse displayed several polyphase systems. The exhibits included a switchboard, polyphase generators, step-up and step-down transformers, transmission line, commercial size induction motors, commercial size synchronous motors, and rotary direct current converters (one of which was operating a railway motor). The working-scale system allowed the public a view of a system of polyphase power which could transmit long distances. Meters and other auxiliary devices were also present.

Tesla displayed the first neon light tubes at the exposition, demonstrating his phosphorescent lighting powered without wires by high-frequency fields. Tesla's lighting inventions exposed to high-frequency currents would bring the gases to incandescence. Tesla displayed the first practical phosphorescent lamps (a precursor to fluorescent lamps). His innovations in this type of light emission were not regularly patented.

Also in the exhibits were Tesla's demonstrations, most notably the "Egg of Columbus". This device explains the principles of the rotating magnetic field and his induction motor. The Egg consisted of a polyphase field coil underneath a plate with a copper egg positioned over the top. When the sequence of the coils were energized, the magnetic field arrangement inductively created a rotation on the egg and made it stand up on end (appearing to resist gravity).

On August 25, Elisha Gray introduced Tesla for the delivery of a lecture on mechanical and electrical oscillators. Tesla explained his work for efficiently increasing the work at high frequency of reciprocation. As Electrical Congress members listened, Tesla delineated mechanisms which could produce oscillations of constant periods irrespective of the pressure applied and irrespective of frictional losses and loads. He explained the working means of producing constant period electric currents (not resorting to spark gaps or breaks) and how to produce these with reliable mechanisms.

The Exposition's illumination with electricity using Tesla's and Westinghouse's alternate current removed any doubt of the utility of the polyphase alternating current.
War of currents
Main article:War of Currents
During this time, direct current was the standard, and Edison was not disposed to lose all his patent royalties to a former employee. Adversaries due to Edison's promotion of DC for electric power distribution over the more efficient alternating current advocated by Tesla, Edison (or, reportedly, one of his employees) employed the tactics of misusing Tesla's patents to construct the first electric chair for the state of New York in order to promote the idea that alternating currents were deadly.

In his work with the rotary magnetic fields, Tesla devised the system for transmission of power over long distances. He partnered with George Westinghouse to commercialize this system. Westinghouse had previously bought the rights to Tesla's polyphase patents and other patents for AC transformers. Experts announced proposals to harness the Niagara Falls for generating electricity. Against General Electric and Edison's proposal, Tesla's AC system won the international Niagara Falls Commission contract. The commission was led by Lord Kelvin and backed by entrepreneurs (such as J.P. Morgan, Lord Rothschild, and John Jacob Astor). Work began in 1893 on the Niagara Falls generation project and Tesla's technology was applied to generate electromagnetic energy from the falls.

Some doubted that the system would generate enough electricity to power industry in Buffalo. Tesla was sure it would work, saying that Niagara Falls had the ability to power the entire eastern U.S. On November 16, 1896, the first transmission of electrical power between two cities was sent from Niagara Falls to industries in Buffalo from the first commercial two-phase power plants (known as hydroelectric generators) at the Edward Dean Adams Station.

The hydroelectric generators were built by Westinghouse Electric Corporation from Tesla's AC system patent designs. Tesla's system designs alleviated the limitations of the previous DC methods. The nameplates on the generators bear Tesla's name. He also set the 60 hertz standard for North America. It took five years to complete the whole facility.

With the financial backing of George Westinghouse, Tesla's AC replaced DC, enormously extending the range and improving the safety and efficiency of power distribution. Tesla's Niagara Falls system marked the end of Edison's roadmap for electrical transmission. Eventually, Edison's GE company converted to the AC system. Tesla's contributions to the modern world are widely regarded as more important and long-lasting, by some, than those of his nemesis and one-time employer, Thomas Edison.

The Nobel Peace Prize for 2006

The Norwegian Nobel Committee has decided to award the Nobel Peace Prize for 2006, divided into two equal parts, to Muhammad Yunus and Grameen Bank for their efforts to create economic and social development from below. Lasting peace can not be achieved unless large population groups find ways in which to break out of poverty. Micro-credit is one such means. Development from below also serves to advance democracy and human rights.

Muhammad Yunus has shown himself to be a leader who has managed to translate visions into practical action for the benefit of millions of people, not only in Bangladesh, but also in many other countries. Loans to poor people without any financial security had appeared to be an impossible idea. From modest beginnings three decades ago, Yunus has, first and foremost through Grameen Bank, developed micro-credit into an ever more important instrument in the struggle against poverty. Grameen Bank has been a source of ideas and models for the many institutions in the field of micro-credit that have sprung up around the world.

Every single individual on earth has both the potential and the right to live a decent life. Across cultures and civilizations, Yunus and Grameen Bank have shown that even the poorest of the poor can work to bring about their own development.

Micro-credit has proved to be an important liberating force in societies where women in particular have to struggle against repressive social and economic conditions. Economic growth and political democracy can not achieve their full potential unless the female half of humanity participates on an equal footing with the male.

Yunus's long-term vision is to eliminate poverty in the world. That vision can not be realised by means of micro-credit alone. But Muhammad Yunus and Grameen Bank have shown that, in the continuing efforts to achieve it, micro-credit must play a major part.

走出去

  这学期开学都快整月了,就出过一次,还是托同学的福,去看中网男子决赛。
  鼓足了充分的勇气,其实这源于我的购物欲,终于第二次跨出了校门:时间是疯狂的十一黄金周,地点是人满为患的北京的人满为患的西单。
  现在想起来,整个下午就在踩与被踩,上电梯和下电梯中无谓地度过。
  晕!怎么就没有一件能看上眼的呢?不行!好不容易出来一趟,岂可空手而归!这不是我的性格。本着一不做,二不休的革命奋斗主义精神,我一定要买!

流年

  流年不利啊!老丢东西,从年头丢到年中。
  真情提示:如果你的QQ号尚未申请密码保护,而且你不想失去这个号码,奉劝你赶紧行动吧!
  接着我还有什么可以丢呢?

  中国人对于“圆”这个几何图案似乎情有独钟:一家人团坐在一张大圆桌围,睁得圆瞪瞪的眼睛,直直地望着漆黑夜空中那一轮皎洁的圆月,口里尝试着圆圆的月饼,心里还时刻充盈着对于圆满幸福的憧憬……
  这就是中国人的“圆”。
  
  现在的我每每读完一本书,或是看完一部电影,总是有些观后感想写,不像小时候,只有在语文老师的“逼迫”下,才会极不情愿地硬着头皮来写一些所谓的“观后感”,类似无病呻吟,假装深沉。毕竟,人老了,老了就开始感悟,回忆自己的经历,品味别人的人生,再接着就是顾影自怜,扼腕叹息,感慨万千了。
  刚读完《边城》,一部老早前就想读的著作——趁这几天假期读几本书,一来可以听听故事打发打发时间,二来陶冶一下丢弃多时的情操,增加一点文学素养,还愿。
  那样的物境,对于我来说还算是熟悉的,尽管没有亲身游历和体验(当时差一点就去了!);那样的人事,对于我来说也见怪不怪,因为质朴的民风下,自然的感情最真实亲切;可是那样的结局,却让我有油然而生的落寞和消沉,尽管也许明天就是那个“明天”,但说又能保证明天不会是那个“永远”?!也许是因为最近的我过于消极,才会有这样可怕的想法,如果换个人来看,说不定他或她就认准了那个“明天”。究竟是我消极还我现实呢?
  我们都渴望圆满,却往往无法直接看到圆满,甚至得不到圆满,心怡得太久太深,心伤得也会更久更深。
  也许我们不应该再天真地幻想什么happy ending,都做一做行尸走肉,来一个无欲则刚!

陌生的熟悉

    不知道其他人有没有这样的情况:本来有很多话想说的,一旦打开这个页面,又突然变得哑口无言,只好完成任务似的写些无关痛痒的废话。
    今天看到了一些自己的影子,很亲切,那瞬间的回味的确很触人。不过所有的一切,就好像梦一样地进行着,自然有做美梦的,也有做噩梦的。
