Main Points:

• "Quanta Magazine" explains an important modern research idea each week. This week, Ben Brubaker unpacks computer science and discusses his reporting highlights.
• Computer science is not just about computers or related topics like software and cybersecurity. It mainly focuses on theoretical computer science which predates modern digital computers.
• Real computers lead to developments in theoretical computer science, like the need for precise mathematical language (algorithms) to describe procedures.
• The questions in theoretical computer science are often simple despite the dense math and acronyms, such as comparing problem difficulties, understanding randomness, and the relation between physics and information.
• In 2022, the author started covering computer science with little knowledge. Two years later, he still learns new things.
• Recent results in theoretical cryptography suggest some quantum physics problems may be outside complexity theory. Also, a tweak to Dijkstra's algorithm makes it unbeatable in many cases.
• The fifth "busy beaver" was definitively identified this year, and the process was recorded in a Discord chat server.
• The author participated in a panel discussion at the Simons Institute about computer science writing.
• An anecdote about a researcher reporting a stolen bicycle shows there's more to computer science than just computer study.

Key Information:

• Edsger Dijkstra's quote: "Computer science is no more about computers than astronomy is about telescopes."
• Theoretical computer science grew from Alan Turing and others' efforts to formalize mathematical processes.
• In 1956, Dijkstra developed an algorithm for finding the shortest routes. By the 1980s, it was proved the best in one sense.
• A team recently discovered a tweak to Dijkstra's algorithm that makes it unbeatable in many cases.
• The fifth "busy beaver" was identified by a group working online.
• The Simons Institute supported the panel discussion and also supports "Quanta" as an independent publication.

Important Details:

• The author's past life as an experimental physicist with limited programming experience.
• The string of recent results in theoretical cryptography and their implications.
• The details of the Discord chat server where the "busy beaver" discovery was recorded.
• The challenges and approach of covering theoretical computer science as a journalist.
• The viral anecdote about the researcher reporting a stolen bicycle.
