“Covers a variety of high-technology skills, such as computers, biology, physics, and geology.”— In-game description

Science is a Fallout, Fallout 2, Fallout 3, Fallout Tactics, Fallout: New Vegas, Van Buren, and J.E. Sawyer's Fallout Role-Playing Game skill.

Fallout, Fallout 2, and Fallout Tactics

$\text{Initial level}\%=25+(2\times\text{Intelligence})$

Example: A starting Intelligence of 5.

$25+(2\times5)=35\%$

The Fallout Tactics 1.27 patch notes readme file says:

“The science bonus to criticals on robots is working properly”

suggesting that Science somehow affects critical chance or effectiveness against robots (at least in Tactics).

Fallout 3

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

Example: A starting Intelligence of 5 and Luck of 5.

$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=15$

Science primarily allows you to hack terminals using a mini-game. Certain terminals have different difficulty levels, and different Science skill levels are required to hack them. The difficulty ratings and skill levels are: very easy (15), easy (25), average (50), hard (75), and very hard (100). Your Science skill relative to the difficulty rating affects how hard the minigame is (at Science 100, average terminals are a breeze, presenting only about 5 possible passwords). Harder terminals have more words, longer words, and fewer brackets.

Interactions that require Science skill

• 50 Science to hack the RobCo production facility mainframe during the quest Wasteland Survival Guide.
• 50 Science to reactivate the robots during the quest Big Trouble in Big Town.
• 60 Science to unlock certain dialog options with Doctor Lesko during the quest Those!. This allows you to learn he had been using a modified form of Forced Evolutionary Virus to induce pyrosis reactions in giant ants, creating fire ants.
• 75 Science to modify healing archways to fully heal the player, though this reduces their number of uses to three. (Mothership Zeta)
• 75 Science to hack the mobile base crawlers' mainframe. (Broken Steel)
• 80 Science to deactivate the repulsion fields aboard the crawler. (Broken Steel)
• With a high Science skill you can bypass the Speech check required to convince John Henry Eden to self destruct during the quest The American Dream.
• Although a high Science skill increases your chances of disarming a slave collar, the Explosives skill is also taken into account. Even when both skills are high, the slave could still blow up, so saving before attempting to disarm a collar is advised.

Fallout: New Vegas

“The Science skill represents your combined scientific knowledge and is primarily used to hack restricted computer terminals. It can be used for conversion and recycling of Energy Weapon ammunition at the workbenches. Some crafting recipes also require Science.”

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

Example: A starting Intelligence of 5 and Luck of 5.

$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=15$

Like in Fallout 3, your Science skill relative to the difficulty rating affects how hard the mini game is. Notably, 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, your Science is used for more than a few random dialogue checks and hacking. Many Workbench crafting recipes, and some Campfire recipes, rely on Science, specifically ones involving Energy Weapons ammunition and chem crafting.
