Temples of Modernity is a painstaking and sensitive work that engages deeply with the internal worlds of scientists in a postcolonial society. It makes interesting points about how religious rituals and festivals helpbuild scientific communities, and argues that the seeds of today’s aggressive expressions of belief in Vedic technology were contained in the same nationalist movement that gave rise to Nehru and his modernist conception of science. India’s scientific institutions, the author suggests, are “temples of modernity” in more ways than one.
