The best part about getting a Veritasium notification is you know the video is guranteed to be interesting and worth your time, plus you get to learn stuff too!
I work in aviation. This forms a large part of the safety design of the aircraft as the operating altitude makes high energy cosmic rays more likely. Luckily we can mitigate it through software such as storing multiple copies of data (usually triplicate) in different physical areas of memory. It has to be different physical areas of memory, because as memory gets smaller, the likelihood of multiple bit flips from one ray increases.
Can't believe I'm old enough to recall this problem in the industry. Actually, there were more problems during that period as well. One such, popped up slightly later called "Ghost capacitance" (but on a PCB). When I created a failure analysis team, we discovered random PCBs that were affected, that took what seemed like forever to find. Those were some fun times though. 🕺💃😊🤘
Lets take a moment to appreciate that this short actually finished what it was trying to say and wasn't clickbait, with no dependence on video context or resolution. Thanks, Veritasium!
As an engineer my heart and soul goes out to whatever poor dudes had to debug that problem.
