Fascinating discussion of the nebulosity of electronic components featuring @robamacl and @mattskala. You don’t have to understand anything about electronics to get the key points (I hope! I don’t understand anything about electronics…)

In technical practice, as in social policy, retaining traditions is often wise (“Chesteron’s Fence”). And sometimes not. We’re seeing catastrophic consequences of retained obsolete traditions in both science and policy in the US covid debacle.https://twitter.com/mattskala/status/1263518727070334976 …

In low temperature scientific work, you can no longer use rubber o-rings to seal flanges. Instead you end up using crushed metal o-rings (Indium is popular). I was taught to apply vacuum grease to the indium wire before crushing it, so it could be easily removed afterward.

I was a guest in a cryo lab during grad school where this practice was regarded with horror. The other students claimed the vacuum grease would be more likely to cause superfluid leaks (very bad). I couldn’t convince them otherwise, and they sure as heck didn’t convince me.
