Abstract
Reyner Banham characterized the Second Machine Age as the age of domestic electronics and synthetic chemistry in opposition to the First. It means technology and science would be popularized in the Second Machine Age. The Second Machine Age began in the mid-50's in which pop culture and SF became popularized. The architects in both Machine Age choose the scientifism as the motive of architectural design. But not all of them approach to the design with the pure theory of science. This study analyses the types of scientifism in architectural design in the 1950's and the 60's based on approaches to technology which might be classified as pragmatic, radical, and pop.
