Do you have any question for now? I just resent the book to you.

kindlychung

I have received your book.
I am considering whether I should print it out.That book focuses on one-variable calculus, I need a solid foundation on that.
Thanks.

you study medicine? Why do you like so solid math? Just curious.

Great! But then since we are not just in the physical world, we need studay more. Like philosophy, LaoZi,... Of course, one focus at a time...

Beautiful sequences, I fin ...

The myth of the origin of life, the myth of self consciousness or spirit or the third yet most important INFORMATION among the other two (mass and energy) that constitude the world,surely need to take some thought.
Or, the ultimate meaning of Life? Lots to think about, isn';t it?

I like Laozi.

That';s an area I';ve been exploring for a long time, don';t have an answer yet, but I';ll keep searching.

Are you a professor?
If yes, what is your research interest?

I used to teach and research math. I have many interests. Related to IT architecture, my interest is software (semi-self-runtime-)evolution.[br][br]-=-=-=-=- 以下内容由 elimqiu 在 时添加 -=-=-=-=-
