The Big Book of Science is an object found in the Fallout franchise. It was written and published before the Great War, and the single book edition continues to be used in Vault 101's school. By reading a Big Book of Science the player's Science skill is increased. It appears in every core game of the franchise as well as in Fallout: Tactics.

In Fallout

In the original Fallout the Big Book of Science is actually a set of books kept together by a belt or cord. It contains information on several scientific fields. Reading the books will make time pass. There are 6 in Fallout 1. One Big Book of Science weighs 5 pounds.

In Fallout 3

In Fallout 3 the Big Book of Science is a different edition from the previous Big

Fallout 3 and New Vegas Model
Fallout 3 and New Vegas Model

Book of Science. As opposed to a bound set of books the Big Book of Science is a very large textbook. It is at least 1000 pages. This edition is the version Vault-Tec used for their East Coast vaults. There are 25 copies that the Lone Wanderer can find while traversing the Capital Wasteland. They weigh 2 pounds and will increase the player's Science skill by 1,or 2 if they have the Comprehension Perk. It is actually possible to get infinite copies of the Big Book of Science by killing the Ant Researcher in Shalebridge and taking it from his corpse. He respawns every 73 hours with another copy in his inventory.

Chemistry Journals

Chemistry Journals are found in Fallout 1 and 2. They use the exact same model as Big Books of Science but they do not increase the player's Science skill and except for a quest to upgrade the player's Power Armor in the original Fallout they are completely useless.
