Ask HN: How to get better knowledge about math notations in computer science

9 点作者 lichtenberger大约 3 年前
Hi all,<p>it&#x27;s now about 10 years, since I finished my masters degree at the university and the math lectures weren&#x27;t my strength either.<p>However, I often times read publications and I mostly skip the math formulas. I guess it&#x27;s time to get better at understanding this stuff (again?).<p>Do you have any tips&#x2F;books&#x2F;resources&#x2F;videos to learn from?<p>kind regards<p>Johannes

Excellent talk by Guy Steele explaining the history of maths&#x2F;comp notations that can probably lead you to the right path through original sources: <a href="https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=dCuZkaaou0Q" rel="nofollow">https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=dCuZkaaou0Q</a><p>Then have a look at this extremely underrated talk by Alexander Stepanov for basically falling in love with maths (he gives a long view of maths in general adorned with beautiful commentary): <a href="https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=fanm5y00joc" rel="nofollow">https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=fanm5y00joc</a>

This resource makes it easy to understand mathematical notations by showing comparisons with simple code [0]. The Wikipedia history section of a mathematical concept is also useful to understand in multiple dimensions. Searching for visualizations or break downs can also be useful.<p>[0] <a href="https:&#x2F;&#x2F;github.com&#x2F;Jam3&#x2F;math-as-code" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Jam3&#x2F;math-as-code</a>

I don&#x27;t know if you mean the logic notation often seen in programming language papers, but it&#x27;s called sequent calculus. Wikipedia page has a good intro and links to further resources:<p><a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Sequent_calculus" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Sequent_calculus</a>

Chapter One of <i>The Art of Compute Programming</i> is a good mathematical foundation.
