A Decades-Old Computer Science Puzzle Was Solved in Two Pages

Posted by in categories: computing, mathematics, science

A paper posted online this month has settled a nearly 30-year-old conjecture about the structure of the fundamental building blocks of computer circuits. This “sensitivity” conjecture has stumped many of the most prominent computer scientists over the years, yet the new proof is so simple that one researcher summed it up in a <a class=”” data-event-click=”{“element”:” ExternalLink”,” outgoingURL”:” [embedTweet url=“1145837576487612416” author=“false”] href=“https://twitter.com/BooleanAnalysis/status/1145837576487612416″ rel=“nofollow noopener noreferrer” target=“_blank”>single tweet.

“This conjecture has stood as one of the most frustrating and embarrassing open problems in all of combinatorics and theoretical computer science,” wrote Scott Aaronson of the University of Texas, Austin, in a blog post. “The list of people who tried to solve it and failed is like a who’s who of discrete math and theoretical computer science,” he added in an email.

The conjecture concerns Boolean functions, rules for transforming a string of input bits (0s and 1s) into a single output bit. One such rule is to output a 1 provided any of the input bits is 1, and a 0 otherwise; another rule is to output a 0 if the string has an even number of 1s, and a 1 otherwise. Every computer circuit is some combination of Boolean functions, making them “the bricks and mortar of whatever you’re doing in computer science,” said Rocco Servedio of Columbia University.

The incredible science exploring how to edit our memories

Posted by in category: science

Two remarkable new studies are suggesting sci-fi stories of memory manipulation may not be so far-fetched. The research describes early proof-of-concept experiments showing how negative emotional associations with traumatic memories can potentially be weakened or even entirely edited out.

Carl Sagan’s most important lesson about science

The thing that Carl Sagan did better than anybody else was connecting to the science through emotion and stories, says NASA’s Michelle Thaller. Watching him when growing up formed Thaller’s vision of what an astronomer could be and inspired her for the rest of her life.
