ESA的CDF Study,好強...
第一次見那麼多未見過的conceptal design
歐洲的力量真非同小可

Stephen Hawking HKUST Lecture


World-renowned scientist and cosmologist Prof Stephen Hawking will deliver an inaugural lecture for the Institute for Advanced Study at HKUST on "The Origin of the Universe" on 15 June 2006.

This will be the first visit to Hong Kong for Prof Hawking, who is currently Lucasian Professor of Mathematics at the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge.

Prof Hawking will discuss theories on the origin of the universe. He will explain how time can have a beginning and the progress made by cosmologists in an area traditionally belonged to theologians and philosophers.

The Institute for Advanced Study (IAS) at HKUST is a key initiative outlined in the University's Strategic Plan: 2005-2020. The first of its kind in Hong Kong, IAS will become a regional and global intellectual center and place Hong Kong firmly on the world map.

Lecture Series: Perspectives on the Origin of the Universe
This series of talks will introduce audiences to current progress on our understanding of the universe. Six renowned physicists and mathematicians will participate in the event. The talks by Dr Michael Kwok-Yee Wong, Dr Tian-Wen Chen and Prof Henry Tye are designed for a general audience with secondary-school-level knowledge of physics and mathematics. A stronger physics or mathematics background would be recommended for the other talks.

 

 
   
A Grass-Roots Approach to Quantum Gravity: The Role of Statistical Physics
Prof Bei-Lok Bernard Hu, University of Maryland
4.00–5.30 pm, 24 May (Wednesday), Lee Wing Tat Lecture Theater (LTD), HKUST
(Language: English)

 

 

Prof. Bei-Lok Hu will tell us the relation of quantum gravity, the most pressing unsolved issue of theoretical physics, and the origin of the universe, the ultimate mystery of Nature, and present one unconventional yet most sensible approach to this theory, from the "bottom-up", without making any assumption on an ultimate "theory of everything". This approach relies more on well-proven theories depicting today's low energy phenomena and large scale structure of spacetime, matched by cosmological observations and experimental data. It begins with General Relativity and Quantum Field Theory, and goes beyond to semiclassical and stochastic gravity, aided by ideas and techniques from nonequilibrium statistical mechanics, fluctuation phenomena, quantum noise and stochastic processes.

 

 

 
   
Hawking and Black Holes: Earlier Work by Hawking and Related Astronomical Observations
Dr Michael Kwok-Yee Wong, HKUST
4.00–5.30 pm, 3 June (Saturday), Lam Woo Lecture Theater (LTB), HKUST
(Language: Cantonese)
 

The Space-time of Hawking: brief introduction on Hawking's life, his work in physics, and his view on the nature of space and time
Dr Tian-Wen Chen, HKUST
4.00–5.30 pm, 11 June (Sunday), Lam Woo Lecture Theater (LTB), HKUST
(Language: Cantonese)

 

 

 

Two talks by Dr Michael Kwok-Yee Wong and Dr Tian-Wen Chen of HKUST will target at secondary-school students interested in knowing more about gravity and cosmology. They will provide the basic but necessary background information on general relativity, black holes and the nature of space and time, with an emphasis on the work of Stephen Hawking.

 

 

 
   
Space-time and the Geometry Behind It
Prof Shing-Tung Yau, CUHK
10.00–11.00 am, 10 June (Saturday), Hong Kong Science Museum
(Co-organized by HKUST, CUHK and Hong Kong Science Museum)
(Language: Cantonese)

 

 

Prof Shing-Tung Yau of the Chinese University of Hong Kong will describe the beautiful geometrical structure of space-time that has evolved from current work on string theory and cosmology, and explain how mathematics and physics seem to be unifying again in an unpredictable and exciting way.

 

 

 
   
How Our Universe Began (String theory perspective)
Prof Henry Tye, Cornell University
4.00–5.30 pm, 13 June (Tuesday), Lam Woo Lecture Theater (LTB), HKUST
(Language: English)

 

 

On 13 June, Prof Henry Tye from Cornell University will explain the origin and structure of the universe from the perspective of string theory. This theory is nowadays considered one of the most plausible candidates for the "theory of everything" and is one of the most mathematically exquisite theories ever developed by mankind.

可觀天文講座及觀星樂 (5月) - 木星

2006年5月
可觀自然教育中心暨天文館主辦
香港天文學會協辦

日期:5月27日(星期六)
時間:晚上7:00 - 9:30
地點:嗇色園可觀自然教育中心暨天文館
   (荃灣荃錦公路101號)
節目:(1) 講座 「木星-科學探索之旅」 (可觀天文館張師良先生主講)
      (2) 數碼立體星象館模擬星空體驗
      (3) 觀星/木星觀測
      (4) 參觀0.5米口徑望遠鏡 (香港天文學會潘德新先生主持)
費用:全免
名額:60


講座內容簡介:
木星,太陽系中的行星之王,直徑達地球的11倍,已知擁有63顆衛星,可說是一個小型的太陽系。長期的觀察可見木星上劇烈的大氣運動,大氣上著名的大紅斑便是一個存在超過400年、有地球3倍大小的風暴,近月木星大氣出現了第二顆紅斑,天文學家稱之為小紅斑,是人類第一次看著紅斑的誕生。

透過先鋒、航行者、伽利略、卡西尼太空探測船,科學家能夠近距離觀測木星系統,如捕捉木衛一艾奧的活火山爆發、探測木衛二歐羅巴的地底海洋、近距離觀察木衛三加美尼的地質活動、認知佈滿隕石坑死寂的木衛四卡尼斯托。此外,哈勃太空望遠鏡、地面的大型望遠鏡也對木星作長時間的觀測,在94年重要的天文現象休梅克利維9號彗星撞木星的時候更發揮重大的作用。


活動內容簡介:
5月是本年木星最接近地球的時間,也是觀測條件最好的時候,講座後還會參觀可觀天文館0.5米口徑巨型望遠鏡觀賞木星、土星、深空天體和春季星座等。

本館新添置了數碼立體星象館。在吹氣的天幕下,利用魚眼數碼投影機,製造出一個虛擬的星空,各位能躺臥於天幕下欣賞銀河和流星雨,仿如到了真實的星空一樣。


參加辦法:
請致電或電郵報名登記
名額有限,先到先得


報名及查詢:
電話 24137122
電郵 astronomy@hokoon.edu.hk


截止日期:5月27日 正午12時


如要取消報名參與當晚活動人士,請於5月27日正午12時前致電可觀天文館,多謝合作。


交通安排:
(1) 於荃灣地鐵站乘搭紅色的士直達(車費約HKD$30)
(2) 駕車者可直接驅車入可觀自然教育中心停泊
