真隨機? 呢樣野哲學界同physics界好似仲拗緊存唔存在
姐係好似你明知下次粒dice一定會出1-6其中一個,但有無方法predict到下次一定會出某一個?呢樣野係一定發生,而差在你可唔可以predict到
骰仔既motion follows classical mechanics,所以只要所有同呢個motion相關既parameters都度得準,再plug落相關既law of physics,理論上就可以predict到
chaotic system係冇辦法predict到 你可以攞到嘅相對準確嘅只可以係所謂嘅distribution/ensemble average
而任何couple to thermal environment嘅molecular system都係chaotic
無法predict係因為measurement無可能準到可以overcome個chaotic system既sensitivity,定係equations of motion描述唔晒個process所有law of physics,同埋真係random,好似係三回事
1. Uncertainty principle limit咗我地對molecular system相關measurement嘅precision
2. molecular system嘅chaotic nature源自於N-body interactions。無論classical mechanics 係咪已經足夠描述個system,都改變唔到或者只可以增加個inherent chaotic nature
3. 有說法係Randomness可能只係一啲chaotic results。取決於可否發現ergodicity之類嘅property,暫時未證明到,我亦諗唔到點樣可以證明到。好大機會最後都只可以停留係哲學層面討論。
可惜molecular system已經細到會比uncertainty影響到,如果唔係,真係想睇下有冇experiments可以quotes哂所以equations完全predict到一個system 做到既過,簡直係determinism既理程碑

想問下數學/stat巴打關於predict 隨機機率既問題
其實有無理論或者研究係做緊點樣去預測下次隨機出現既係乜? 係真隨機唔是偽隨機
其實係有無可能做到?
