I think exact values and formulas should be a research item in itself. when people made handguns at first they knew they could kill people, when people make handguns now, they know the approximate speed at which the bullet leaves the gun, how much of an impact force it has, and how much it'll travel in distance.

Also the formulas are like the formulas of physics. hence I'd keep the formulas hidden until you have researched physics.

Offcourse in the game you could write them down once you had them researched and never need em again. you could prevent this by making a semirandom universial constant. say, gravity is 9.8 m/s² today on earth, and another game its 11,4 m/s² slight differences, which still make it realistic, but make your previously noted formulas off by quite a margein.

Would be great imho, would also make the theorethical sciences more than just tools to unlock the others.

Because the exact knowledge of the formulas gives you a more detailed view of the game and helps you to build better designs, i think it's something you should earn and spend resources on.
