Dr. Ken Baake of Texas Tech University presented "The Rhetoric of Science and How Metaphor Constitutes Knowledge in Science" at our first co-hosted Webinar on 23 February 2012. The rhetoric of science has been a flourishing academic sub-discipline since Thomas Kuhn’s book, The Structure of Scientific Revolutions, published in the 1960s, revealing the means by which knowledge in science comes to be enshrined textually. This role of language in science was the topic of Ken Baake’s STC Webinar. He reviewed the rhetoric of science as a field of study, and then discussed his own area of research—the means by which metaphor as a rhetorical device helps to constitute knowledge in science. Baake also highlighted findings from his 2003 book on metaphor and science and presented examples of the role of metaphor in the sciences. He also offered many insights for technical communicators who are involved in science writing. We welcome comments or input on future Webinar topics.
