[請益] 投資獲益是否違反熱力學第二定律?
不好意思 舊文被砍文 所以我改標題分類後再重po一次
很抱歉推文內容就沒有保存下來
熱力學的第二定律(物理過程會伴隨有熵增)告訴我們
如果你對於一個熱機(heat engine)堤供能量(熱能)
熱機做功的效率絕對不會超過卡諾熱機效率(這是熱力學第二定律的另一種形式)
如果把"金融市場"看成是一個熱機
那麼投資者丟錢進去就好像對於熱機提供熱能
熱機做功之後產生的產品再換回錢
這個過程會經過兩次的能量轉換 投資的錢-> 產品 ; 產品-> 收益
按照熱力學二定律
投資的錢扣掉收益 一定是都是要賠錢的
(因為轉換效率最多就是卡諾熱機的效率 1-T_C/T_H)
不過經濟學或是一般做生意的經驗告訴我們
都是認為投資的目的就是可以賺錢的 報酬率大於一
這之中的落差是怎麼產生的???
