I&#x27;ve never met Professor Knuth, but he taught me a lesson that I treasure.<p>I suppose these days the best way I can describe it is that his example &quot;de-weaponized&quot; Christianity for me.<p>It could be said that religion is like a radioactive material; too much of it all together can go boom.<p>But Prof Knuth&#x27;s lesson for me was that I didn&#x27;t have to leave my mind at the door outside when entering a church. I found his book, &quot;Things a Computer Scientist Rarely Talks About&quot;, a series of talks that he gave at an MIT Symposium.<p>And I don&#x27;t, much. Talk about these things. And there&#x27;s lots I don&#x27;t like about church and the role we seem to press upon it.<p>But compassion and honesty seem to work pretty good. I&#x27;m grateful.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Things_a_Computer_Scientist_Rarely_Talks_About" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Things_a_Computer_Scientist_Ra...</a>

I attended this in person on Dec 7 (as I have every year it&#x27;s been held, since 2014). A good text outline of the talk by David Cassel was just posted today, here: <a href="https:&#x2F;&#x2F;thenewstack.io&#x2F;donald-knuths-2022-christmas-tree-lecture-is-about-trees&#x2F;" rel="nofollow">https:&#x2F;&#x2F;thenewstack.io&#x2F;donald-knuths-2022-christmas-tree-lec...</a>

The most nostalgic part of this is that he&#x27;s doing the presentation with a camera pointing at paper&#x2F;books setup. Back in the 90&#x27;s when I was talking CS, professors routinely presented by writing on plastic sheets using an overhead projector.<p>Not sure what I was expecting from Knuth though - maybe I was imagining some amazing TeX-based live diagramming environment, but then again he doesn&#x27;t really use email which should have tempered these expectations.

People get mad that George RR Martin can&#x27;t get past his 5th book in a decade.<p>And here, Knuth has to spend like 40 years writing his 4th book (which has now expanded into 3 books unexpectedly: 4a, 4b and 4c).<p>&#x2F;s<p>I joke of course. But TAOCP&#x27;s future chapters are some of the most interesting computer challenges available. Every section Knuth writes is another treasure.<p>It&#x27;s clear that the computer science field really did take off in the 70s and 80s, so it makes a lot of sense why Volume 4 has expanded so much and scope-creeped.
