The Compass 指南針

Diagram of a Ming dynasty mariner's compass
Main article: Compass
The earliest reference to magnetism in Chinese literature is found in a 4th century BC book called Book of the Devil Valley Master (鬼穀子): "The lodestone makes iron come or it attracts it."
The earliest reference to a magnetic device used as a "direction finder" is in a Song Dynasty book dated to AD 1040-44. Here there is a description of an iron "south-pointing fish" floating in a bowl of water, aligning itself to the south. The device is recommended as a means of orientation "in the obscurity of the night." However, the first suspended magnetic needle compass was written of by Shen Kuo in his book of AD 1088.
For most of Chinese history, the compass that remained in use was in the form of a magnetic needle floating in a bowl of water. According to Needham, the Chinese in the Song Dynasty and continuing Yuan Dynasty did make use of a dry compass, although this type never became as widely used in China as the wet compass.
The dry compass used in China was a dry suspension compass, a wooden frame crafted in the shape of a turtle hung upside down by a board, with the loadstone sealed in by wax, and if rotated, the needle at the tail would always point in the northern cardinal direction. Although the 14th century European compass-card in box frame and dry pivot needle was adopted in China after its use was taken by Japanese pirates in the 16th century (who had in turn learned of it from Europeans), the Chinese design of the suspended dry compass persisted in use well into the 18th century.

Gunpowder 火葯

Handgun from the Yuan dynasty, circa 1300s.
Main article: History of gunpowder
The prevailing academic consensus is that gunpowder was discovered in the 9th century by Chinese alchemists searching for an elixir of immortality. By the time the Song Dynasty treatise, Wujing Zongyao (武經總要), was written by Zeng Gongliang and Yang Weide in AD 1044, the various Chinese formulas for gunpowder held levels of nitrate in the range of 27% to 50%. By the end of the 12th century, Chinese formulas of gunpowder had a level of nitrate capable of bursting through cast iron metal containers, in the form of the earliest hollow, gunpowder-filled grenade bombs.
In AD 1280, the bomb store of the large gunpowder arsenal at Weiyang accidentally caught fire, which proced such a massive explosion that a team of Chinese inspectors at the site a week later deced that some 100 guards had been killed instantly, with wooden beams and pillars blown sky high and landing at a distance of over 10 li (~2 mi. or ~3.2 km) away from the explosion.
By the time of Jiao Yu and his Huolongjing in the mid 14th century, the explosive potential of gunpowder was perfected, as the level of nitrate in gunpowder formulas had risen to a range of 12% to 91%, with at least 6 different formulas in use that are considered to have maximum explosive potential for gunpowder. By that time, the Chinese had discovered how to create explosive cannonballs by packing their hollow shells with this nitrate-enhanced gunpowder.

Papermaking 造紙術

Main article: Papermaking
Further information: Science and technology of the Han Dynasty
Papermaking has traditionally been traced to China about AD 105, when Cai Lun, an official attached to the Imperial court ring the Han Dynasty (202 BC-AD 220), created a sheet of paper using mulberry and other bast fibres along with fishnets, old rags, and hemp waste. However a recent archaeological discovery has been reported from near Dunhuang of paper with writing on it dating to 8 BC.
While paper used for wrapping and padding was used in China since the 2nd century BC, paper used as a writing medium only became widespread by the 3rd century. By the 6th century in China, sheets of paper were beginning to be used for toilet paper as well. During the Tang Dynasty (AD 618–907) paper was folded and sewn into square bags to preserve the flavor of tea. The Song Dynasty (AD 960–1279) that followed was the first government to issue paper currency.

Printing 印刷術

Main article: History of typography in East Asia
The Chinese invention of Woodblock printing, at some point before the first dated book in 868 (the Diamond Sutra), proced the world's first print culture. According to A. Hyatt Mayor, curator at the Metropolitan Museum of Art, "it was the Chinese who really discovered the means of communication that was to dominate until our age." Woodblock printing was better suited to Chinese characters than movable type, which the Chinese also invented, but which did not replace woodblock printing. Western printing presses, although introced in the 16th century, were not widely used in China until the 19th century. China, along with Korea, was one of the last countries to adopt them.

The intricate frontispiece of the Diamond Sutra from Tang Dynasty China, AD 868 (British Museum)
Woodblock printing for textiles, on the other hand, preceded text printing by centuries in all cultures, and is first found in China at around 220, then Egypt in the 4th century, and reached Europe by the 14th century or before, via the Islamic world, and by around 1400 was being used on paper for old master prints and playing cards. In another analysis Hyatt Mayor states that "a little before 1400 Europeans had enough paper to begin making holy images and playing cards in woodcut. They need not have learned woodcut from the Chinese, because they had been using woodblocks for about 1,000 years to stamp designs on linen."
Printing in China was further advanced by the 11th century, as it was written by the Song Dynasty scientist and statesman Shen Kuo (1031-1095) that the common artisan Bi Sheng (990-1051) invented ceramic movable type printing.Then there were those such as Wang Zhen (fl. 1290-1333) and Hua Sui (1439-1513), the former of whom invented wooden movable type printing in China, the latter of whom invented metal movable type printing in China. Movable type printing was a tedious process if one were to assemble thousands of indivial characters for the printing of simply one or a few books, but if used for printing thousands of books, the process was efficient and rapid enough to be successful and highly employed. Indeed, there were many cities in China where movable type printing, in wooden and metal form, was adopted by the enterprises of wealthy local families or large private instries. The Qing Dynasty court sponsored enormous printing projects using woodblock movable type printing ring the 18th century. Although superseded by western printing techniques, woodblock movable type printing remains in use in isolated communities in China.別要我逐句翻譯，我辦不了

⑷ 發明家英語介紹

英語屬於印歐語系中日耳曼語族下的西日耳曼語支，由古代從歐洲大陸移民大不列顛島的盎格魯、撒克遜和朱特部落的日耳曼人所說的語言演變而來，並通過英國的殖民活動傳播到世界各地。
早期日耳曼人部落（弗里西族、盎格魯族、撒克遜族與朱特族）移民到英格蘭，英語就是從他們的語言中變化繼承下來。據《盎格魯撒克遜編年史》記載，公元449年左右，不列顛群島國王伏提庚（Vortigern）邀請「盎格魯親戚們」來幫助他對抗皮克特人。作為回報，他賜予盎格魯族東南部的領土。隨後他又進一步尋求支援，撒克遜族、盎格魯族與朱特族人紛紛前來。《編年史》記載，最終這些「移民」建立了七個王國：諾森伯利亞、麥西亞、東盎格利亞、肯特、埃塞克斯、蘇塞克斯、威塞克斯。
日爾曼人入侵後，統治了當地的凱爾特語民族，本地語言主要於蘇格蘭、威爾士、康沃爾與愛爾蘭存活了下來。這些入侵者的語言逐漸形成了「古英語」，與近代弗里西語極為相象。English（英格蘭人、英語）、England（英格蘭）和East Anglia（東盎格利亞）這三個詞是分別從描繪盎格魯族的詞彙發展而來：Englisc、 Angelcynn、Englaland。
1066年諾曼征服後三百年內，英格蘭的國王只講法語。因此一大批法語詞彙進入了古英語，古英語本身也失去了大部分曲折變化，進化為中古英語。1500年左右的母音大推移將中古英語變形為近代英語。古英語最著名的文學作品是《貝奧武夫》，中古英語則是《坎特伯雷故事集》。
近代英語在莎士比亞所處的時期開始繁榮，一些學者將之分為早期近代英語與後期近代英語，分界線為1800年左右。隨著不列顛對全世界大部分地區的佔領和殖民，當地語言也很大程度上影響了英語的發展。

美國大選結果將短暫影響全球市場美國大選結果不單只左右美國的走向，也會影響美股和全球股市在未來四年的走勢。按歷史傳統，美國華爾街較不喜歡民主黨。但是，這次美國大選卻遇上百年一遇的全球金融海嘯，美國經濟基本上已經進入衰退，當地人心急切求變。不過，現在更為復雜的是衰退只是剛剛開始，蕭條陰影正籠罩市場。奧巴馬的當選能否成為改善美國經濟的興奮劑，或替經濟帶來轉機，環球市場正密切關注。奧巴馬支持實施金融救援計劃，不過筆者觀察其言論，他認為救市只是臨時措施，應同時加強市場監管，在救市過程中也應推動實施為中產階級減稅和刺激經濟增長的計劃。奧巴馬獲勝，筆者估計他會更多考慮窮人的利益，另外可能也會改變對外出口方面的政策。從政策面看，美國在稅收、能源、社會保障、醫療保健、住房以及對外貿易等方面或將出現改變，奧巴馬入主白宮的未來四年，將對美國經濟產生深遠影響，因此我們必須留意新總統上任後的實際行動。在美國大選前，內地A股市場再度出現了調整，市場萎縮反映了資金尚未恢復投資熱情，即使連續推出利好政策，也未能激起市場的參與熱情。但是在美國大選塵埃落定後，市場在短期未必對市場看得太淡。在這前提下，環球氣氛有望打破內地市場悶局，但是這並不代表經濟基本面轉好。美國大選不會改變經濟衰退的趨勢，即使短期美股出現進一步的反彈，筆者也只能將之定性為反彈，不排除在明年年中前再次尋底的可能性。經過上月市場暴跌後，A股市場在短期內暴挫的機會較小，不過投資者應該保持謹慎。在目前經濟衰退的情況下，企業盈利前景黯淡，因此市場仍存在不少價值被高估的企業，若沒有業績支撐，股價將進一步的回歸到更為理性的水平。雖然美股短期出現了反彈跡象，但這並不代表A股將同樣迎接反彈。短期氣氛可能改善，當前A股市場仍然處於企業業績不明朗期，持有現金或將仍是內地基金界明年初最佳的投資策略。山寨文化折射中國尷尬境地!從山寨手機開始，一股洶涌的山寨文化浪潮席捲了整個中國大地，就連周圍第三世界小國甚至是歐美等強國也不同程度的被山寨所影響。「山寨」一詞,原本指沒牌照、難進正規渠道的小廠家、小作坊,引申為盜版、剽竊、仿製的同義詞。現在，各行各業以山寨手機為榜樣，自發的發起了學山寨運動，消費者對於購買山寨產品樂此不疲，學者、專家們鋪天蓋地的撰寫文章大肆的評論山寨，就連新聞聯播也開始報道山寨現象。其實，山寨的產業鏈正在形成，而寨文化對中國的影響才剛剛開始。說起山寨的流行，不得不從山寨手機說起。山寨手機規避了行業監管、研發、知識產權、售後服務的限制，套上明星臉的外形以超低廉的價格推向市場，迅速吸引眾多粉絲，牢牢佔有一部分市場份額，割據一方。價格優勢是山寨手機的殺手鐧，同時也是對壟斷利益集團反抗的最強音。很早以前，為了對企業或個人的腦力成果進行保護，西方國家頒布了一系列的政策來保護知識產權，目的是保護開發者的利益，鼓勵企業與個人進行創新。時至今日，大財團依靠不斷的發展與市場競爭，積累了空前的資本與技術優勢，幾個大公司由於掌握核心技術，可以在一個產業領域內呼風喚雨，甚至能夠左右這個產業內產品的價格。由於技術壁壘的限制，中小企業無法與壟斷企業競爭，就算是自己能夠獨立生產的商品也要向掌握核心技術的企業交納專利技術使用費，或者直接購買核心零部件。這就好像某人發現咖啡里加上牛奶也很好喝，於是便申請專利，別人不可以這么做，想喝加牛奶的咖啡只能去他那裡買。這種「技術」在享受到一段時間的保護、得到了很多利益的時候就應該可以開放了，可是當人們都自發的掌握這種「技術」以後，政府仍舊還在保護，既然你們自己也會做了，那就交專利費好了，交了錢就允許你們自己做。直到很久以後，就連退休的老奶奶也會做了，根本就沒人再去交專利費了，這種「專利技術」終於沒有保護的價值了，政府就把它徹底開放了。原來那個人早就賺得數錢數到手發軟，然後發明了更好的方法再去申請專利，或者擁有了巨無霸式的連鎖品牌「黑白分明」。壟斷企業利用原有的優勢與知識產權政策，不斷穩固自己的壟斷地位，然後再對中小企業進行剝削。保護知識產權政策初衷是保護自主創新的利益與鼓勵技術競爭，可是到如今卻成了既得利益集團穩固自己地位、打壓弱小競爭者的工具。這些弱小的企業在面對大財團時就正好折射出了中國在面對歐美強國時的尷尬處境。從新中國成立的那天開始，中國的領導人一直致力於把中國建設成為世界上的工業強國。時過境遷，中國已經真的變成世界工廠，可是中國人卻發現，發達國家在中國設廠，大肆揮霍著中國的電力、煤炭、石油等基礎生產資源，生產的原材料也在中國就地取材，還要享受各種優惠政策與減稅待遇，解決的就業問題也是以對中國工人階級進行更殘酷的剝削為代價換來的，中國只能得到利潤的一小部分。在技術領域內，中國不但沒有任何優勢，而且根本就沒有發言權，只能是受欺壓的角色。西方國家的財團原本就是勾結本國政府利用技術打壓中小企業，保護自己的既得利益，實現了政府與財團的雙贏。現在他們又有了一個新的理由來維持現在這個局面，那就是利用技術資本對以中國為首的第三世界國家進行剝削。打著保護知識的幌子，實則進行壟斷經營，壓制新興國家與企業的發展，使他們永遠趴在產業鏈的下游。中國確實很無奈，這是後來者的煩惱，也是任何後來者所必須面對的，已經形成的格局是那麼牢固，中國想擠到上去分一杯羹是那麼困難，因為原有秩序的建立者利用「知識產權」這把利器把中國牢牢壓在身下，被剝奪了腦力勞動權利的中國只能乖乖的進行體力勞動。其實，我們所用的盜版軟體就是模仿最好的山寨產品了，中國政府的態度一直就是很曖昧，一方面也希望建立良好的知識產權秩序，另一方面對歐美的技術壟斷深惡痛絕，希望藉助山寨的力量以最小的成本發展中國的信息化建設，對歐美國家的技術成果以巧取的方式武裝自己。微軟的黑屏事件其實是微軟公司與中國政府互相的無奈。可是，在全球化進程加快的今天，這種不那麼正大光明的做法越來越沒有空間了，特別是中國想要成為強國，僅僅停留在山寨層次是不行的。就算是在國內佔山為王，天皇老子管不了，但終究不能進入國際市場進行競爭，中華民族是有遠大抱負的，不可能滿足於山寨檔次的。山寨產品想要繼續發展，最根本的就是賺取利潤，然後進行研發，搖身變成真正的科技產品。山寨產品是否能夠完成不那麼光彩的原始積累，以反壟斷英雄的形象屹立起來，我們只能拭目以待了。

冰箱的由來( The origin of refrigerator)
By the mid-nineteenth century, the term"icebox"had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.

Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.

But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, more explained, was that farmers would no longer have to travel to market at night in order to keep their proce cool.

直到19世紀中期，"冰箱"這個名詞才進入了美國語言，但冰僅僅只是開始影響美國普通市民的飲食。 冰的買賣隨著城市的發展而發展。 冰被用在旅館、酒館、醫院以及被一些有眼光的城市商人用於肉、魚和黃油的保鮮。 內戰(1861-1865)之後，冰被用於冷藏貨車，同時也進入了民用。 甚至在1880年前，半數在紐約、費城和巴爾的摩銷售的冰，三分之一在波士頓和芝加哥銷售的冰進入家庭使用，因為一種新的家庭設備，冰箱，即現代冰箱的前身，被發明了。 製造一台有效率的冰箱不像我們想像的那麼簡單。 19世紀早期，關於對冷藏科學至關重要的熱物理知識是很淺陋的。 認為最好的冰箱應該防止冰的融化這樣一個普遍的觀點顯然是錯誤的，因為正是冰的融化起了製冷作用。 早期為節省冰的努力，包括用毯子把冰包起來，使得冰不能發揮它的作用。 直到近19世紀末，發明家們才成功地找到有效率的冰箱所需要的精確的隔熱和循環的精確平衡。 但早在1803年，一位有發明天才的馬里蘭農場主，托馬斯·莫爾，找到了正確方法。 他擁有一個農場，離華盛頓約20英里，那裡的喬治鎮村莊是集市中心。 當他用自己設計的冰箱運送黃油去市場時，他發現顧客們會走過裝在競爭者桶里那些迅速融化的黃油而給他比市價更高的價格買他仍然新鮮堅硬，整齊地切成一磅一塊的黃油。 莫爾說他的冰箱的一個好處是使得農民們不必在夜裡上路去市場以保持他們產品的低溫。

Alexander Graham Bell was born in Scotland. His mother, who was deaf, was a musician and a painter of portraits. His father, who taught deaf people how to speak, invented "Visible Speech". This was a code which showed how the tongue, lips, and throat were positioned to make speech sounds. Graham, or "Aleck", as his family called him, was interested in working with the deaf throughout his life.

Thomas Watson became an associate of Bell. He made parts and built models of Bell's inventions. One day while they were working Bell accidently heard the sound of a plucked reed * coming over the telegraph wire. Watson had been tuning the metal reeds in the next room. Bell drew up a plan for the telephone and they continued to experiment. The next day he transmitted the famous words, "Mr. Watson, come here. I want you!" A few months later on Feb. 14, 1876, he applied for a patent on his telephone.

He continued to invent other things. He developed a method of making phonograph * records on a wax disc. He made an iron breathing lung, and a device for locating icebergs at sea. He experimented with sheep. He was interested in kites that could lift a man, and he invented a hydrofoil * which set a world speed record of over 70 miles per hour.
