Science! is primarily a pre-requisite for most modifications to energy weapons.
In addition, there are many modifications and crafting recipes that primarily rely on a different perk (such as Gun Nut, Armorer or Demolition Expert) but also require ranks in Science! (such as the cryogenic grenade or power armor).
Science! also unlocks a few buildable objects for settlements, such as a laser turret and disco ball. Most notably, however, Science! Rank 1 unlocks the Industrial Water Purifiers, which are best utilized for the most efficient passive caps income in the game.
