statistic of the day

From Donald MacKenzie's An Engine, Not a Camera: How Financial Models Shape Markets:

"In 1951, just over 2 percent of the pages ... the American Economic Review, contained an equation."

BTW, for those who think I only complain about sociology, the MacKenzie book is marvelous. It's a case study of the effect of academic economics on the economy (more specifically, on finance, or more specifically still, on the creation and operation of options markets).
