They're obviously not mundane, otherwise NASA would have designed Hubble to use equivalent optics. Any actually interesting technology would be under a Secrecy Order [1] and the patents wouldn't see the light of day, perhaps ever. The few examples we know of were definitely c…

Give a modern Apple CPU to some chip experts in the 80s and they'd no doubt be amazed and have many questions about the details, but they would have a theoretical basis for understanding the premise of the thing. Give the same chip to Isaac Newton or Archimedes and it would be a completely different story. To them, a C…
