“Science” ≠ Technology!

If you give them the technology without giving them stuff like empiricism and cultural acceptance of critical thinking, they’ll just worship it like any other faith, and stagnate for the next thousand years.

Inversely, you don’t even need to give them too much technology, because if you just give them stuff like evidence-based medicine, the printing press, rigorous experimentation and reproducibility, and a couple institutes dedicated to the craft, plus a couple starting points, then they’ll figure it on their own soon enough (assuming an overall stable civilization).
