Nikola Tesla and You

Nikola Tesla and You is a book in Fallout 3. It can be seen in several locations during the game and sometimes in the loading screen of the game. Reading this book improves your Energy Weapons skill by 1 (2 with Comprehension).

Note if you're planning on collecting all 25 of them, you will have to disarm the bomb in Megaton. Until you do so, you are unable to get the house and therefore unable to pick up the skill book in Megaton.
