Personally I think the NC equivalent is the good old great library. Its relatively easy to get it, even on deity.
- Start off with a monument to get culture going, chose a culture pantheon, and find city states, then beeline for the civic.
- Try to keep your cap able to produce it when it is avaliable, so don't build more then one settler in it to let your cap grow
- Build the campus and library in good time
- Remember you need a flat land next to campus to build it
- Don't spend science to finish that many ancient and classical techs, since you get boosts for every tech from the wonder
- Research the three first, and the science tech, then beeline for tech for industrial zone or something
If/when you succeed in building it, you will most probably be on par (or close to) in science with the AI, even on deity.
This strategy is OP with China, but works for every civ.
