is used,whether it is a blessing or a curse to mankind,depends on mankind and not on the instrument.A knife is useful,but it can also kill....——Albert Einstein 錯誤更正 • consider（考慮）——觀察群星，思索吉凶：英語單詞 consider （考慮）與古代的占星術有關。它源自拉丁語 considerare ，由 con （一道，集群）+ siderare （源自 sideris ，星星）搆成，字面意思 就是“仔細觀察群星，思索其中蘊含的吉凶信息” ，后來詞義逐漸 演變為“觀察、研究，琢磨、思索、考慮” 。 • 小拓展：英語單詞 sider 源自拉丁語 sideris ，表示“星星” 。古人發現星 星掉下來后變成了隕石，而隕石的主要成分是鐵。所以詞根 sider 又衍生 出“鐵”的含義。
up a private observatory and made extensive measurements of binary stars and on 25 Nov 1850 discovered Saturn’s inner Crepe Ring (independently of American William Bond). In 1864, he was the first to make an accurate map of Mars. He was called ”Eagle-eyed Dawes” for the keenness of his sight with a telescope (though otherwise, he was very near-sighted). He devised a useful empirical formula by which the resolving power of a telescope - known as the Dawes limit - could be quickly determined. For a given telescope with an aperture of d cm, a double star of separation 11/d arcseconds or more can be resolved, that is, be visually recognized as two stars rather than one. Prince Louis-Victor de Broglie Died 19 Mar 1987 at age 94 (born 15 Aug 1892). Louis Victor Pierre Raymond duc de Broglie was a French physicist best known for his research on quantum theory and for his discovery of the wave nature of electrons. De Broglie was of the French aristocracy - hence the title “duc”(Prince). In 1923, as part of his Ph.D. thesis, he argued that since light could be seen to behave under some conditions as particles (photoelectric effect) and other times as waves (diffraction), we should consider that matter has the same ambiguity of possessing both particle and wave properties. For this, he was awarded the 1929 Nobel Prize for Physics.
