Ask HN: Where do you find unknown knowledge?
As an engineer where do you find new knowledge?
* Engineer related topics (like new way of architecting/designing your software, gotchas/failures in microservices, simple fascinated algorithms and so on)
* Real world physics/chemistry (why explosion happens, how metal is formed, why stars explode and so on)
* Human/social knowledge. (why we buy products, why we love, why brexit happened)
Please share your source of knowledge, youtube or google doesn't make sense.
