Every time data travels — from smartphones to the cloud, or across the vacuum of space — it relies on a silent but vigilant guardian in the form of error-correcting codes. These codes, baked into nearly every digital system, are designed to detect and repair any errors that noise, interference or cosmic rays might inflict.
Highlighted moments
error-correcting codes is the story of math fighting noise.
“I could send you A and B, and then A plus B mod two, or A, X, or B.”
“What polar codes utilize is a transformation that basically will transform a whole bunch of channels that are kind of equally not great into a few channels that are fantastic and a few channels that are really, really bad.”
“the types of errors that are introduced when doing DNA storage are different than the types of errors that you expect in silicon devices or something like that. And you have to designing different codes to deal with them.”
