The Ghost In Science (サイエンスの幽霊, Saiensu no Yūrei) is Susumu Hirasawa's second solo album.

The Ghost in Science is marked by a whimsical, futuristic thematic in which Hirasawa paints himself as a mad scientist.

It has a sound similar to other Hirasawa albums of the same era, though puts greater emphasis on electronic elements.

All tracks are written and arranged by Susumu Hirasawa except "Fish Song", cowritten by Akiro "Kamio" Arishima with strings coarranged by Kayo "Kokubo" Matsumoto.
