《虚籁》:
I love logic, especially Modal Logic and its “peripherals", and “I Want to Be a Logician" (paraphrase of the title I Want to Be a Mathematician by Paul Halmos).
Don't just read it; fight it! Ask your own questions, look for your own examples, discover your own proofs. Is the hypothesis necessary? Is the converse true? What happens in the classical special case? What about the degenerate cases? Where does the proof use the hypothesis? (P. Halmos, I Want to Be a Mathematician)
The fear of stumbling makes the mind hold tightly onto the handrail of logic. (André Gide, Les Nouvelles Nourritures)
If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is. (von Neumann)
If you zip through a page in less than an hour, you are probably going too fast. (Sheldon Axler: Linear Algebra Done Right)Notes:
Cats$^\sim\omega^\sim$ DuoDuo is a very cute kitty, he is my partner, my all tenderness and the fluffy dream!

The best way to achieve a goal is to devote 100% of your time and energy to it. When I decided I was going to be a physicist, I didn't take some other job in case it didn't work out. (S7E13)
