Game theory

This term instead of taking a philosophy course, I am taking a economics course, game theory. Technically, I am not taking a course, I did not register. I am just going to the lecture to audit the course off the record. It is one of those huge lecture with over a hundred of students. The structure of the course is fairly one way, the professor explain the course material in class and then hand out homework assignment. Unlike the philosophy course, I learn by interacting with the professor, this course is just a one way street of absorbing knowledge. I figure if I don’t need the credit and I don’t need another to mark my assignment, why don’t I just sit in the lecture and learn for free.

I am taking game theory not only because I am interested in economics, it is also I need this knowledge for more advance moral or political philosophy. Utilitarianism is always and will always be an important moral or justice theory. There are new research to field on applying game theory concept to calculate the utility function to determine whether something is moral or evil. Knowing game theory will give allow me to give more quantitative argument when I am making a moral claim.

In this course, I am using Wiki to take lecture notes. My ultimate goal is to create a knowledge database for my studies and I am experimenting with Wiki. Here is my lecture notes

紐約大蘋果(三) – 無畏號軍事博物館

若果參加旅行團去紐約﹐信相應該不會參觀博物館﹐更加不會看百老匯歌劇。這些地方沒有自由神像﹐帝國大廈﹐中央公園出名﹐而然這些才是紐約真正吸引人的魅力所在﹐但絕對比那些景點值得參觀。去看名勝景點沒有什麼得著﹐最多只是拍張風景照片﹐證明曾經到此一遊﹐倒不如去獨一無異的博物館增廣見聞﹐到百老匯觀賞世界級的文化演出。這次行程去頭去尾只有三天﹐實在不夠時間隨心所欲地看過飽﹐只能參觀兩間博物館和看了兩齣百老匯。

不要以為行博物館是扮高級很沉悶﹐位於曼哈頓東區第八十六號碼頭的無畏號軍事博物館﹐絕對是到紐約一定要看的地方。若果沒有時間的話﹐不看自由神像不看帝國大廈﹐也一定要騰空時間參觀這個博物館。無畏號航空母艦建於一九四三年﹐參加過太平洋戰役﹐被神風敢死隊重創。第二次大戰後改建為噴機空母﹐參加過韓戰和越戰﹐亦是水星太空任務的海上回收基地。八二年退役後改建停泊在紐約改建為博物館﹐零六年入船塢大修翻新去年底才重新開幕。

空母的格納庫改建為巨型室內展覽廳﹐除了陳例退役戰機和水星太空倉外﹐還有展覽介紹海軍﹐空軍和太空任務的各種相關知識。艦中央的飛機升降台改建為巨型電影院﹐播放無畏號歷史的記錄片。在二次大戰魚雷轟炸機前設有互動劇場﹐讓遊客體會神風敢死隊的可怖。劇場用多角度投映器配合環迴立體聲的效果﹐一邊畫面播放菲律賓海戰的歷史片段﹐一邊畫面播放演員水兵的旁述﹐講述無畏號如何受到自殺式攻擊的經過。在畫面播到日本戰機上戰艦一刻﹐劇場煙霧彌曼紅光四閃﹐爆炸聲震耳欲聾。觀眾有如回到過去的歷史中﹐親身經歷當日慘烈的戰況。觀眾站立觀看劇場的位置﹐正是當年被自殺機命中﹐受到重創的人間煉獄。互動展覽區有戰機駕駛倉改建的飛行模疑遊戲﹐讓遊客試試難度極高把飛機降落空母。還有很多展品解說航空母艦的操作﹐讓遊客體驗水兵在海上的生活。最受遊客歡迎的展品是救援直升機﹐可以讓遊客坐進駕駛倉扮機師拍照留念。

空母的飛行甲板改建為戰機花園﹐擺放了十多架退役戰機。有最快飛行記錄保持者黑鳥﹐也有從第一代噴射戰機到F-14和F-16的美國戰機。不單止有戰機還有直升機,不止有美國戰機﹐連蘇聯的米格戰機也有。可惜天公不造美﹐我參觀無畏號時剛好下雨﹐只好趕快冒雨拍飛機照﹐沒有閒情逸緻去捕捉每架飛機的雄姿。空母大部份地方對外開放﹐遊客可以在空母自由走動﹐沿著樓梯爬上爬落。到船頭看船錨的巨大鐵鍊﹐到船倉看水兵起居飲食的地方﹐看飛行員出動前的簡報室﹐看戰術室解碼室醫院﹐看艦外的防空炮等等。最好玩是參觀艦橋﹐所有設施也任摸任動﹐背景播放當年的無線電通訊﹐讓遊客可以一嘗角色扮演的心願。遊客可以坐上艦長的司令椅幻想自己指揮作戰。也可以站到舵手岡位的掌舵﹐幻想自己在駕駛二百多米的巨船。大既軍用設備以堅固耐用見稱﹐不怕遊人會弄壞艦橋的東西。

除了航空母艦外﹐博物館碼頭還停泊了一艘退役核子導彈潛艇以及和諧式飛機﹐同樣也可以讓遊客入內參觀。我們去的那天潛艇正在維修﹐結果緣慳一面。和諧式飛機是世界唯一的超音速客機﹐可惜營運成本太貴被迫退役。雖然和諧式飛機的票價十分昂貴﹐機內的座位並不是太舒服﹐可能是機身修長沒有太多空間的關係。和諧式飛機的三角型機翼﹐巨型的噴射引擎﹐與一般民航機有外觀有很多分呢。飛機腹部下面是露天茶座﹐把整架飛機當成一個巨型涼亭﹐看著河邊的景色是休息的好地方。在離去前軍事迷不要錯過博物館的禮物店﹐有很多無畏號的紀念品賣。

可惜我只有三個小時的空檔去無畏號軍事博物館﹐實在不夠時間仔細欣賞所有展品﹐這個博物館可以玩上一整天。不過我老婆投訴走上走落很辛苦﹐她對戰機也不是特別有興趣。如果是一班人去紐約旅遊﹐不妨考慮男女分開活動﹐女仕們去第五大道購物﹐男仕們則可以去看無畏號﹐不需要什麼也一齊活動大家互悶。

BC election

Today I fulfilled my duty as a citizen, I cast my vote to elect the BC provincial government. The candidate I voted for in my riding lost, but the party I voted for won the election. The Liberal party is able to formed a majority government winning 47 out of 85 seats in the parliament. The best of all is the outcome of the referendum on the election system. The good old simple majority vote scheme defeated the new multiple transferable vote scheme that is so complex that no one really understand how it works.

I was away taking a vacation last week and I did not follow the election news closely. Actually I don’t have to get news to decide my vote. I hardly know the candidate I vote for and I just found out his name on my drive to the voting station. I don’t vote for the person, I vote for the party. I am not really a support of the Liberal, in fact I think they are far from a good government. My concern is the alternative is far much worse. The NDP is a left leaning party. If they win the election, it is guarantee they will raise tax and screw up the economy. The Green Party is even worse, their are policy is so extreme that you start to question their sanity.

It is quite interesting to see a few odd parties shows up in the ballot. There are the libertarian, the communist party, the conservatives and some party support BC independent. Too bad the race in my riding is very tight between Liberal and NDP, I can’t afford to waste my vote. If the Liberal is leading a comfort margin, I may give my vote to the communist party. Communist party of Canada, that’s cool!
