Science (Fallout: New Vegas)

Science is a skill in Fallout: New Vegas. It determines the chance to hack computers, get extra info from terminals, talk to specific persons, get more dialogue options.

Initial level

 * $$\begin{matrix}\text{Initial}\\\text{level}\end{matrix}=2+(2\times\text{Intelligence})+\left\lceil\frac{\text{Luck}}{2}\right\rceil$$

Example: A starting Intelligence of 5 and Luck of 5.
 * $$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=15$$

Description
Like in Fallout 3, one's Science skill relative to the difficulty rating affects how hard the mini game is. At Science 100, even Hard terminals will have very few words to choose from. This can possibly be as low as 5 possible passwords which, combined with the Computer Whiz perk, means an 80% chance of getting most terminals off the bat without even having to look at the words.

Unlike Fallout 3, one's Science skill is used for more than dialogue checks and hacking. Many workbench crafting recipes, and some campfire recipes, rely on Science, specifically ones involving Energy Weapons ammunition and chem crafting.
