The Science skill represents your combined scientific knowledge, and is primarily used to hack restricted computer terminals. It can also be used to recycle Energy Weapons and ammunition at workbenches.

Again, like Lockpick, you’ll encounter terminals with varying difficulties which you’ll typically want to hack. Also like Lockpick you will be able to get your Science skill up to 80 and just fill in the last 20 points with a Programmer’s Digest for the [Very Hard] hacks… provided you have Comprehension, of course. The crafting is somewhat moot, as Stimpaks require a score of 70 and components that are more annoying to find than simply paying the Caps for the Stimpak. Everything else that’s useful, like ammo recycling or Doctor’s Bags, typically have a much lower requirement.
