世紀神秘光影秀—本世紀時間最長的日全食今天登場,雖然台灣只能看到最多百分之八十六點八的日偏食,但是,透過網路及電視直播,民眾依然可以飽覽大陸、印度日全食的壯麗奇景。專家建議,除了抬頭看太陽變化,也可低頭體會周邊環境變化。

這場世紀天文大戲歷時超過兩小時,中央氣象局估算,台北今天早上八點廿三分,太陽會從上方偏左處開始出現缺角,慢慢往下擴展,九點四十分缺角最大(稱為「食甚」)。

之後,缺角會從下方偏左處慢慢消失,十一時五分太陽回復原狀。台灣其他地區的日偏食過程差不多,只是時間有一點差距、太陽被遮住的面積不同。

在台灣,太陽被「吃掉」的面積(食分)最大出現在馬祖,有百分之八十六點八,苗栗以北可觀察到八成以上的食分。墾丁食分最小,只有百分之六十八點六。

包括台北市立天文館在內的許多國內外網站都有日全食直播;公共電視與TVBS今天早上現場直播日全食畫面。台大天文所教授孫維新建議,如果想舒適地同時看到日偏食和日全食,可以到兼具室內和室外兩種活動空間的環境:室內有電視或網路看日全食直播,室外可觀察日偏食。

孫維新說,日偏食的太陽變化不會太快,偶爾出外用日食眼鏡看一下就可以,每次不要超過十秒,千萬不可用眼直視。

中央大學天文所教授陳文屏指出,除了抬頭看太陽的光影轉換,也要體驗周遭環境變化。日全食發生時,溫度變低,造成空氣流動,天色灰暗,會有「陰風陣陣」的詭異感覺。

「觀察動物的反應也很有趣」,陳文屏說,原本「倦鳥」才會歸巢,但起床不久的鳥兒突然發現天色變暗,也會匆忙趕回家;貓狗也可能有異常舉動。


The Democratic-controlled U.S. Congress on Thursday approved budget blueprints embracing President Barack Obama's agenda but leaving many hard choices until later and a government deeply in the red.



Electronic mail, often abbreviated as email or e-mail, is a method of exchanging digital messages, designed primarily for human use. E-mail systems are based on a dstore-and-forward model in which e-mail computer server systems accept, forward, deliver and store messages on behalf of users, who only need to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled device (e.g., a personal computer) for the duration of message submission or retrieval. Rarely is e-mail transmitted directly from one user's device to another's.



According to Albert Einstein's special theory of relativity, the speed of light is an important constant connecting space and time in the unified structure of spacetime. As such, it defines the conversion between mass and energy and is an upper bound on the speed at which matter and information can travel. It is the speed of travel of all electromagnetic radiation in free space, and is believed to be the speed of gravitational waves. In an inertial frame of reference, light in vacuum always travels at c. When light passes through a transparent material, such as glass or air, its speed is reduced. The ratio between the speed of light in vacuum and the speed of light in a material is called the refractive index of the material.



Long after the end of Egypt's own pyramid-building period, a burst of pyramid-building occurred in what is present-day Sudan, after much of Egypt came under the rule of the Kings of Napata. While Napatan rule was brief and ceased in 661 BC, the Egyptian influence made an indelible impression, and during the later Sudanese Kingdom of Meroe (approximately in the period between 300 BC–300 AD) this flowered into a full-blown pyramid-building revival, which saw more than two hundred indigenous, but Egyptian-inspired royal pyramid-tombs constructed in the vicinity of the kingdom's capital city.



In humans, caffeine is a central nervous system (CNS) stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Beverages containing caffeine, such as coffee, tea, soft drinks, and energy drinks enjoy great popularity. Caffeine is the world's most widely consumed psychoactive substance, but unlike many other psychoactive substances it is legal and unregulated in nearly all jurisdictions. In North America, 90% of adults consume caffeine daily. The U.S. Food and Drug Administration lists caffeine as a "multiple purpose generally recognized as safe food substance".



A moving company, removalist, or van line is a company that helps people and businesses relocate their goods from one place to another. Typically they use moving vans, but for international moves or where storage is required, they may use special containerised vans or shipping containers.





National companies are typically organized with local branches or affiliated agents. That affiliation may be in the form of a franchise, wherein the local agent is a franchise of a national company, or a cooperative, wherein the local agent owns a share of the national company. There are also many small independent moving companies who operate within any given local area. In the United States all legitimate moving companies must be licensed with the Federal Highway Administration and/or their State Commerce Commission.





Embedded within the moving industry are the services of truck/trailer/moving equipment rental companies and companies selling moving supplies for people who want to pack and move themselves. Then they use a professional mover to load a moving van, drive it to the new residence and then unload it there. Rental companies usually offer some training information for DIY movers who will be using their rental trucks, trailers or equipment to relocate themselves.





Visual Studio includes a code editor supporting IntelliSense as well as code refactoring. The integrated debugger works both as a source-level debugger and a machine-level debugger. Other built-in tools include a forms designer for building GUI applications, web designer, class designer, and database schema designer. It allows plug-ins to be added that enhance the functionality at almost every level - including adding support for source control systems (like Subversion and Visual SourceSafe) to adding new toolsets like editors and visual designers for domain-specific languages or toolsets for other aspects of the software development lifecycle (like the Team Foundation Server client: Team Explorer).



After heated debate as to whether the federal government had the authority to accept the gift, Congress accepted the legacy bequeathed to the nation and pledged the faith of the United States to the charitable trust July 1, 1836. Eight years later, Congress passed an act establishing the Smithsonian Institution, a hybrid public/private partnership, and the act was signed into law on August 10, 1846 by James Polk. The bill was drafted by Indiana Democratic Congressman Robert Dale Owen, a Socialist and son of Robert Owen, the father of the cooperative movement.



Metaphysics investigates principles of reality transcending those of any particular science. Cosmology and ontology are traditional branches of metaphysics. It is concerned with explaining the fundamental nature of being and the world. Someone who studies metaphysics would be called either a "metaphysician" or a "metaphysicist".



The Bible uses eleven chapters to talk about what happened from the beginning of the universe to the dawn of human civilization. These chapters make up 1 percent of Bible. This small portion should not be a clear explanation of how everything began. It suggests that perhaps God doesn’t want to make a clear explanation of these things in the Bible. The scientific explanations of the history of the universe and life on earth are expected to be discovered by people with our talents endowed by God.





People who keep saying that Christianity is unscientific always use the first 1 percent of the Bible to support this idea. This 1 percent of the Bible really looks mythological. However, they should feel tired of doing so after a certain point. Although the other 99 percent has many miraculous events, too, these events were supposed to happen in solid historical settings, and no scientific law can give a proof showing that they couldn’t happen.





The viewpoint here is called theistic evolution, proposed by some Christians. This book takes such an approach on this issue because personally I accept it. Besides, this viewpoint fits the big picture of this book.
