Black hole thermodynamics

Beyond black holes

Hawking and Page showed that black hole thermodynamics is more general than black holes, that cosmological event horizons also have an entropy and temperature.

More fundamentally, ‘t Hooft and Susskind used the laws of black hole thermodynamics to argue for a general Holographic Principle of nature, which asserts that consistent theories of gravity and quantum mechanics must be lower dimensional. Though not yet fully understood in general, the holographic principle is central to theories like the AdS/CFT correspondence.

Job: Meaning of Life 2

.

Your life would have no meaning if you just stay at home, using all the time thinking about the meaning of life.

.

Every day, we face thousands of problems.

In order to survive, we have to create thousands of solutions to those thousands of problems.

Some of your solutions are not only useful for yourself,

but also useful for a lot of others.

.

Why not publish them?

係咁咖啦

（安：我們現在社會的運作方式，只是眾多可能方式的其中一個。而大部分人，卻想不到還有其他可能。）

（安：無錯。有很多人也患上了「係咁咖啦症候群」。他們不當地預設了「現存的東西/制度是『理所當然』的，所以不能改變，亦不應改變。」）

「係咁咖啦症候群」患者，不當地將「自己」和「社會/世界」分開了：「這個社會的人，控制這個社會怎樣運作。而我並不是「社會」，所以唯有接受現存的社會制度，即使自己有多麼不喜歡。」
