“The Science skill represents your combined scientific knowledge, and is primarily used to hack restricted computer terminals.”

Just like Lockpick , but for computers! Granted, hacking is less useful in many ways. A great deal of computers unlock safes, and many others just disable turrets. Still, it’s experience, and there are plenty of situations in which it is useful. Some of which are even exclusive to Science . Keep in mind you also need it for the excellent Cyborg perk. It’s a consideration for a tag skill, although Lockpick is probably more useful early on.
