UV divergences

Recall that the UV divergences allow you to divide theories to renormalizable and nonrenormalizable ones – the renormalizable ones only force you to choose a finite number of parameters and cancel their corresponding infinite parts by counterterms.

Prayer 2.3

二十八

子曰

吾十有五而志於學
三十而立
四十而不惑
五十而知天命
六十而耳順
七十而從心所欲不踰矩

The Master said, “At fifteen, I had my mind bent on learning.

“At thirty, I stood firm. “At forty, I had no doubts. “At fifty, I knew the decrees of Heaven. “At sixty, my ear was an obedient organ for the reception of truth. “At seventy, I could follow what my heart desired, without transgressing what was right.

永恆價值 1.1

這段改編自 2010 年 4 月 3 日的對話。

(安:我現在的那份工作,內容沒有什麼意義;好像在不斷大規模地,浪費著自己的生命似的。但是,在我現在的心目中,又暫時想像不到,其他有什麼工作是有意義的,而又值得我去追求。)

那樣,兩害取其輕之下,為了保障你的經濟生命安全,你就應該保留現在的那份工作,毋須想太多。

(安:但是,我又過得十分不開心。試想想,每星期有五天是工作天,而每一工作天的大部分時間,我存在於工作的環境之中。再加上我還有幾十年才退休。我十分不希望,我大部分的人生,就那樣荒唐地度過。)
