我本科是学数学的，一开始在写证明上特别费劲。后来啃完 Clive Newstead 的《An Infinite Descent into Pure Mathematics》，收获特别大。这本书就是专门为了让数学底子薄的人入门纯数学基础而设计的。读着读着，不知不觉就能熟练写证明了。https://infinitedescent.xyz/…
I did math in undergrad and struggled with proofs at first. I learned a lot from working through An Infinite Descent into Pure Mathematics by Clive Newstead. It's designed to get someone with minimal math background started with the basics of pure math. Becoming comfortable with proofs happens along the way. https://infinitedescent.xyz/…
很难明确说是具体哪一个瞬间。不过我想列几本让我体会到数学之美与乐趣的书：1. Paul Lockhart 的《Measurement》；2. Clive Newstead 的《An Infinite Descent into Pure Mathematics》（可在 https://infinitedescent.xyz/ 免费阅读），它教会了我基础离散数学和证明书写；3. Apostol 的《Calculus Vol 1》，简直太优美了。
It is very hard to pinpoint a single moment. Rather I would like to list a few books that I feel showed me that mathematics can be beautiful and interesting. 1. Measurement by Paul Lockhart 2. An Infinite Descent into Pure Mathematics by Clive Newstead (available @ https://infinitedescent.xyz/). It taught me basic discrete math and proof writing. 3. Apostol's Calculus Vol 1. It is just so beautiful.

这本书是能替代楼主推荐的那本吗？还是说《An Infinite Descent into Pure Mathematics》是一本配套补充的书？
Does this replace the OP? Or is "An Infinite Descent into Pure Mathematics" a complementary book?
