"Sounds correct.  Do snowflakes have six-sided structure under a microscope?  Where I come from, that happens because molecules with two hydrogen and one oxygen have a least-energy crystal configuration that's hexagonal.  If all of that is still true and for the same reasons, then I still know how to make advanced steel and build electrical generators, and the methodology I know to generate more of that knowledge will apply unchanged.  Male and female reversible contraception... was tech in a relatively advanced state where I can't reproduce it directly.  I can reproduce the methodology that generates it."
