  1. 全球科技革命

  2. 教學目標 瞭解科技發展的概況以及它們對人類社會和自然環境可能造成的影響和衝擊，進而珍惜寶貴生命、重視生態環境及保護有限資源。

  3. 成績計算方式 • 平時成績(40%): • 不定期點名，缺課一次扣學期成績4分。 • 小考、討論、報告等 • 期中評量(30%)：紙筆測驗 • 期末評量(30%)：紙筆測驗 • 分數調整:90分以上至少5% • 注意事項: • 缺課過多會影響成績，導致成績不及格 • 上課不要隨便交談、走動、接聽電話

  4. Forty years ago, when I was a student, ….

  5. 計算尺（slide ruler) 計算尺是現代電子計算機問世前，理工科師生常用之計算工具。昔日流行的計算尺如今被電子計算機淘汰，不可否認由下列原因導致。(1) 計算尺固定板或滑動板上設置的數字倘若超過四位以上數字時，難以掌握。嶄新的電子計算機則有10 Digits或10+2 Digits等可見精密之相差。(2) 使用計算尺執行計算時，預先考慮，計算操作的前後次序方能求出精確的答案。 (3) 使用計算尺時，解答所費時間比現代電子計算機冗長又容易出錯。 Source: http://gallery.lib.ntu.edu.tw/archives/427

  6. 土木工程師常常需要要計算大量位值的數(例如測量)。大量位值的加減已令人頭痛不已，更何況大量位值的乘除。這令人產生一個疑問，是否有方法能精確且快捷地計算大量位值的數呢？土木工程師常常需要要計算大量位值的數(例如測量)。大量位值的加減已令人頭痛不已，更何況大量位值的乘除。這令人產生一個疑問，是否有方法能精確且快捷地計算大量位值的數呢？ Source: http://en.wikipedia.org/wiki/Mathematical_table

  7. Good or bad?

  8. What’s New Let's look at some things that exist now that didn't 20 years ago. 1) The internet 2) Cell phones 3) The home computer as is today. 4) Electronic funds transfer (EFT) was in its infancy.5) Flat screen tv's 6) Satellite navigation was a dream for the average personThe list goes on and on.

  9. “What’s New?” since Rio 1992What did not exist or was not well-known in 1992? Source: UNEP, 2011, Keeping Track of Our Changing Environment: From Rio to Rio+20 (1992-2012)

  10. The “global village” has developed rapidly on the basis of new technology 5 billion people around the world use mobile phone technology (ITU2010) Source: UNEP, 2011, Keeping Track of Our Changing Environment: From Rio to Rio+20 (1992-2012)

  11. The one thing we can count on in the future is continual technological change.

  12. The world is always changing…Good change or Bad? • The answers to such problems are not always simple. • Who’s right? If both views have merit, how do we weight the tradeoffs and make a decision?

  13. Revolution(革命) • A revolution is a fundamental change that takes place in a relatively short period of time. • The Industrial Revolutionwas a period from the 18th to the 19th century where major changes in agriculture, manufacturing, mining, transportation, and technology had a profound effect on the social, economic and cultural conditions of the times.

  14. 工業革命以來，快速進步的科技，讓地球人類享受生活上的舒適與便利，但也帶來環境惡化和資源耗竭的問題。工業革命以來，快速進步的科技，讓地球人類享受生活上的舒適與便利，但也帶來環境惡化和資源耗竭的問題。 • 環境惡化 • 生態破壞 • 環境汙染 • 臭氧層破壞 • 全球變遷 • 資源耗竭 • 能源 • 水資源 • 土地農業及食物
