Source of Information

The insight of Bennett on Maxwell’s daemon shows that the information can not be easily erased. By the time symmetry of physical laws, the information can not be easily created, either.
There is this ad hoc observer in quantum mechanics that can collapse the state of a system and create information. And there is also this black hole of Hawking that seems to erase information. How are they connected?

風動、樹動

今天的天氣一反多日來的酷寒,有一點春風徐來味道。在戶外短暫的步行竟讓人有幾分沉醉的感覺。范仲淹在岳陽樓記中自勉要『不以物喜,不以己悲。』。但想想,在這世上有什麼不是『物』呢?而又有什麼是『己』呢?這些難道不就是我們在認定上有意無意下所作的選擇嗎?

無中生有

研亦的腦中想的都是什麼樣的事情呢?她不舒服的時候會不安或哭是可以了解,但有是候還可以看到她的笑,甚至是在睡覺的時候。不知道她是想到了什麼…生物的知覺和記憶是如何形成的呢?其中有多少是遺傳下來的?而其他的又是如何建構出來的呢?

Equivalent Trade

It’s more importance to recognize equivalence in things around us than to focus on favoritism. First of all, this helps us find different solutions to one given problem thus increase the chance of resolution. Secondly, this helps us choose quickly when the scale is tilted. Besides, we don’t need to invent/learn new tricks when the old ones will do.
