Sciences and Studies

This list defines 633 sciences, arts and studies of various degrees of respectability and rarity, ranging from the common and esteemed (chemistry) to the obscure and quirky (peristerophily). Over the past century, the range and scope of scientific endeavours has expanded exponentially, so that practically any field of study has a name associated with it. Most of these terms end in 'ology', from the Greek logos, meaning 'word'.
