Sunday, November 08, 2009 Everything counts...If you are not better than the others, you better work harder than all others. 24 weeks to go for HKCEE... 20 weeks to go for HKAL... The more you play now, the less you can play in your future... The more effort you pay now, the less effort you need to pay later in order to survive... Your future is on your hand, you are the only one who can change it. Do something before it's too late!!!
Sunday, November 01, 2009 To all my students, "Practice Makes Perfect"!Something I want to share with all my students... Something I ignored when I was young... Something I understand it for too late ... Something I really want you to understand, sooner or later ... Here is a greeting on my bday from my student last year, I wish you can learn what he experienced...  Nichol Tsang 24 October at 23:34 Dear Chiu Sir, Firstly, Happy Birthday! How are you? I hope you still remember me.. :p I am now studying in uk, dunno if you are surprise.=) Really want to say thank you to you. From you, I witness " Practice makes Perfect " The maths teachers here in uk don't give us much sums to do, but I finished all the sums in my textbook even they are pretty easy. =] and fortunately I got a full mark in every maths tests I done in uk. However my HK friends don't, they had little errors. :p I finally understand what do you mean by "careless" isn't an excuse of not getting high marks. Anyway, thank you. Happy Birthday again ^^ Nichol Tsang Saturday, October 24, 2009 Two to the power TenYes, it's 2 to the power 10 again... Getting Old...doesn't want people to know... Thank you all again for everything today...you made my day wonderful and unforgettable! Quite touching for that video, you are just too nice to me... thanks again to 5B, 4F and 5D..... don't know how to repay you all. Also, thank you for the cakes, chocolate, and those encouragement... Wish us all happy for every of our days! Thursday, October 15, 2009 HKU 181st Congregation8th December, 2009 @ AsiaWorld-Expo Wednesday, October 07, 2009 Congratulations to Prof. Charles Kao, a Nobel Physics Prize winner, also a Josephian.(星島日報 報道)有「光纖之父」之稱的中大前校長高錕與兩名美籍科學家博伊爾及史密斯，共享今年諾貝爾物理學獎，成為港人之光。諾貝爾基金會讚揚高錕對光纖傳導研究的貢獻，以及另兩位得主發明應用於數碼攝影的電荷耦合元件，開啟了現今的資訊科技革命，為互聯網時代奠定基礎。高錕表示，從來沒有想過會獲獎，感到非常驚喜。 現年七十六歲的高錕，是繼另一位美籍華人崔琦後，第二名曾在香港接受教育的學者獲得諾貝爾獎 。在今年三位得主中，他分得總獎金一千萬瑞典 克朗（一千一百多萬港元）的一半，即約五百六十萬港元。高錕擁有英國 和美國 國籍，亦持有香港身分證。 「沒想過獲獎，非常驚喜」 高錕昨透過中大副校長楊綱凱回應說：「我對於獲頒諾貝爾物理學獎深感榮幸。諾貝爾獎鮮有表彰應用科學的成就，我從來沒有想過會獲獎，感到非常驚喜。」高錕又說，「過去四十年，光纖大大促進了資訊世界的發展及進步；亦有賴光纖的出現，這個喜訊已於瞬間傳到千里。」 特首：有承擔的教育家 行政長官 曾蔭權 昨亦祝賀高錕獲頒諾貝爾物理學獎，指該獎項是科學界最高榮譽，認同高錕不但是一位傑出科學家，亦是一位謙謙君子和有承擔的教育家。香港能夠有一位如此出類拔萃人物，是港人的無比驕傲。 影像音訊秒間傳遍全球 瑞典皇家科學院諾貝爾獎委員會表揚高錕在光通訊科技，在光導纖維的研究上取得了突破性的成就。 聲明表示：「如果我們拆開鋪設在地球的光纖，可駁成長達超過十億公里的線，足以圍繞地球超過二萬五千次，而且它目前以每小時數以千公里計的速度增長。這些玻璃纖維促進了互聯網等全球寬頻通訊的發展，讓短訊、音樂、影像和錄像能在秒間傳訊到全球。」 高錕於一九六六年發表劃時代的論文《光頻率介質纖維表面波導》，提出長程及高資訊量光通訊所需的絕緣性纖維的結構和材料特性，開創性地提出如果利用帶有包層材料的石英玻璃光學纖維（光纖）來進行光通信，能夠讓光在光纖中傳播超過一百公里，遠超過當時實驗室的成果。 根據此原理，四年後消耗小於每公里二十分貝的石英單模光纖誕生，自此徹底改變了人類的通訊模式。 與兩科學家瓜分物理獎 今年物理學獎另一半獎金由發明電荷耦合元件（Charge-Coupled Device，CCD）的博伊爾（Willard Boyle）及史密斯（George Smith）瓜分，以表揚他們根據愛因斯坦的光電效應理論，在一九六九年首次發明了設有數碼感應器的影像科技，為攝影帶來革命，除了使用菲林，還能通過電子科技捕捉光線。 電荷耦合元件是一種半導體成像電路，利用光電效應，在短時間將大量畫素所收集到的光轉換成電子訊息，是數碼攝影機的「電子眼」。 此外，電荷耦合元件也廣泛應用於醫療和天文儀器，小至顯微影像，大至宇宙觀測，全部都受惠於這種發明。八十五歲的博伊爾和七十九歲的史密斯是在被視為「電訊支柱」的貝爾實驗室發明電荷耦合元件。 It's a pity that I dare not to ask him to take a photo with me when he came back to our school last year.... Please watch 傑出華人系列:高錕 .... it's inspiring even he's not a Nobel Prize Winner at the time of the interview.
