在香港修讀認知科學

在網上發現有人有興趣在香港修讀認知科學。其實，可以到香港大學修讀的。近年來，認知科學有長足發展可能因為電腦技術及人共知能的高速發展。大家可以想像人類大腦像一個電腦。現在把人類知識體系及邏輯思考的內部運作規則尋找出來。譬如人腦怎樣為事物建立規則，組織，記憶，尋找，建立關係，更新資料及關係，最後怎樣學習新的知識。

可是，如果是普通的中學生怎樣可以修讀呢？原來HKVU香港虛擬大學都有同樣課程，都是香港大學所提供，但他容許中學生報名。真是有趣。

認知科學

認知科學cognitive science到底是什麼呢？跟我們有什麼切身關係呢？簡單來說，從＂認知＂著手，什麼是＂認知＂？

＂認知＂是 我們如何認識及了解外界的事物。人靠感官接觸外界，把聲音及光轉變為腦部神經的化學信息，得到了畫面及聲音。譬如我們看電影，便是把外界光影信息，傳入我 們的大腦。再經過連串複雜認知過程，得出一些理解，譬如我們聽懂了演員的說話或者看懂了演員的動作。大腦把這些理解與記憶整合並分析，得到了我們所說的意 義甚至更高層次的道德觀念。好像色戒中，我們看見易先生這樣對待王小姐，我們會發出疑問。我們會懷疑角色是否講大話，或者比較記憶中所曾見過的事情，最後 以自己的價值觀來評論他的所作所為。

可見，認知科學所牽涉的科學領域很廣泛，包括了生理學，心理學，哲學，語言學，計算科學。

生理學從科學角度解釋人類感官如何接收外界事物的刺激，因而身體所產生的反應。

心理學解釋了人類的行為，感覺，情感，壓力等等。

語言學則分析說話中的含意，語言環境對字眼產生了什麼影響。

哲學則探討人類及人生中所有的東西，什麼是生，什麼是死，什麼是幸福，什麼是快樂，什麼是真相等等。

計算科學則協助我們建立人工智能和情景模擬，從中以新角度研究智能及行為模式是怎樣一回事。

Enjoy yourself, it's later than you think

Enjoy yourself, it's later than you think
Enjoy yourself, while you're still in the pink
The years go by, as quickly as you wink
Enjoy yourself, enjoy yourself, it's later than you think

Hello, I'm Terry, and I'm going to enjoy myself first

It's good to be wise when you're young
'Cos you can only be young but the once
Enjoy yourself and have lots of fun
So glad and live life longer than you've ever done

Enjoy yourself, it's later than you think
Enjoy yourself, while you're still in the pink
The years go by, as quickly as you wink
Enjoy yourself, enjoy yourself, it's later than you think

Never right, yes I know
Get wisdom, knowledge and understanding
These three, were given free by the maker
Go to school, learn the rules, don't be no faker
It's not wise for you to be a foot stool

Enjoy yourself, it's later than you think
Enjoy yourself, while you're still in the pink
The years go by, as quickly as you wink
Enjoy yourself, enjoy yourself, it's later than you think

Enjoy yourself, it's later than you think
Enjoy yourself, while you're still in the pink
The years go by, as quickly as you wink
Enjoy yourself, enjoy yourself, it's later than you think

今晚聽Uncle Ray的那個電台節目，聽到了這首歌＂Enjoy yourself, it's later than you think＂。如果懂得這首歌，便應該或多或少知道它的副歌部份就是＂歡樂今宵＂的主題歌。

日頭猛做，到依家輕鬆下，食過晚飯，要休息返一陣，大家暢聚，無綫有好節目，歡歡樂樂，笑笑談談，我地齊齊陪伴你！

如果同句並排便知道怎樣唱出來：
Enjoy yourself(日頭猛做),
it's later than you think(到依家輕鬆下)
Enjoy yourself(食過晚飯),
while you're still in the pink (要休息返一陣)
The years go by(大家暢聚),
as quickly as you wink (無綫有好節目)
Enjoy yourself(歡歡樂樂),
enjoy yourself(笑笑談談),
it's later than you think(我地齊齊陪伴你)
