The Ragged Edge of Science

Blurb

The Ragged Edge of Science is a science book by L. Sprague de Camp, illustrated by Don Simpson. It was first published by Owlswick Press in 1980.
The book is a collection of twenty-two articles on various curiosities and wonders exploring the boundaries between science and pseudo-science. "The[ir] common thread is [their] skeptical takes on subjects that are often muddled by paranormal and pseudoscientific claims." De Camp viewed such phenomena from a skeptically rational viewpoint, pointing out the fallacies in supernatural and otherwise fantastic explanations. His debunking efforts were an important and characteristic feature of his nonfiction, and the present collection is a notable instance of it.
The book's constituent articles were originally published in a variety of science magazines, science fiction magazines, and other publications from 1950-1976.
