Waalsové

Waalsové is the Czech plural form used for people bearing the surname Waals. The name itself is of Dutch origin, derived from van der Waals, meaning “from the Waals” (the Waals region). In Czech usage, foreign surnames are commonly inflected to form the plural with the -ové ending, so Waalsové denotes members of the Waals family.

Historically, the most prominent bearer associated with the name is Johannes Diderik van der Waals (1837–1923), a Dutch physicist whose work on real gases led to the Van der Waals equation of state and to the concept of intermolecular forces later called Van der Waals forces. In Czech-language texts, the surname is often kept in its original Dutch form as van der Waals, while Waalsové can be used when speaking of multiple family members.

In scientific and pedagogical contexts, the name Van der Waals appears widely, referring to the forces and interactions named after the physicist. Czech translations of these concepts typically render them as Van der Waalsovy síly or Van der Waalsovy interakce, depending on the context.
