The 20th century has witnessed the emergence of the physics of fluctuating systems both statistical and quantum. This to some extent explains the important role played by functional integrals in modern physics. We describe a few striking examples of physics problems where using path and, more generally, field integrals has proved decisive.
Keywords: fluctuating system, statistical mechanics, quantum mechanics, functional integral.
