"With insight, wit, and warmth, Wertheim offers a look into the hearts and minds of the "outsider" physicists… an entry point into a fascinating corner of pseudoscience." –
Publishers Weekly "[A] compassionate look at those on the fringe…Wertheim covers new ground in this treatment of how science is communicated and what it means for scientific ideas that aren’t part of the discussion…Both conversational and easy to read, this is an accessible guide to the world of the weird." –
Library Journal "Fascinating, bizarre, and provocative…[a] brilliant thesis…Any reader who found pleasure and excitement in
The Men Who Stare at Goats or
Sex and Rockets: The Occult World of Jack Parsons will derive similar joy from this finely wrought, sympathetic, and stimulating survey of gonzo ingenuity in the service of science." –
Barnes & Noble Review "Delightful…However misguided, the characters in
Physics on the Fringe are their own men, doing their own work, like Newton, Faraday, and other past heroes. In some ways, Wertheim’s book is a paean to small science." –
The American Scholar "A compelling study…Wertheim unfolds a fascinating chronicle of such ‘down the rabbit hole’ thinking, but far from taking the ironic high ground, the tone is respectful and sympathetic." –
The Outsider "Entertaining and philosophically provocative…Wertheim serves up her philosophical punchline toward the end of her book when she turns her attention to mainstream physics and cosmology. She [senses] that some popular suppositions—notably the notion that reality consists of extremely tiny strings wriggling in hyperspaces of a dozen or more dimensions, or that our universe is just one of an infinite number of universes—verge on pseudoscience, because they are even less experimentally testable than Carter's circlon theory… On the other hand, Wertheim is gently, affectionately skeptical of the outsider physicists, too…She nonetheless suggests that, given how far mainstream physics has drifted from a grounding in empirical evidence, perhaps we should judge all physics theories according to their beauty, elegance, and craftsmanship. And just as the art world occasionally embraces outsiders who lack formal training, so perhaps physics—and physics writers—should look more favorably upon the imaginings of autodidacts like Carter." –
Chronicle of Higher Education "For the past 15 years, Margaret Wertheim has been collecting similar works by such hermit scientists, or what she calls "outsider physicists." With the patience of Job she has undertaken the task of carefully reading as many "theories of everything" as she could get her hands on. In "Physics on the Fringe," Ms. Wertheim takes us on a tour of "outsider" ideas and with an eye toward challenging our preconceptions of what science is, how it works and who it is for. As you'd expect, the book is entertaining—even laugh-out-loud funny in places—, but it's equally enlightening. In an elegant narrative Ms. Wertheim has taken on one of the knottiest conundrums in the philosophy of science, the demarcation problem—that is, how to find criteria to define the boundary between science and pseudoscience….let's not dismiss outsiders before giving them their day in court, as Ms. Wertheim has done in this splendid book." –
The Wall Street Journal "Wertheim, an accomplished science writer, has collected such [fringe] texts for years now and sympathetically narrates many of them for us. Such ephemera are very hard to come by, given their frequent encounters with the trash heap, and her archival efforts are to be lauded (as is the renewed attention she brings to mathematician Augustus De Morgan’s delightful 1872 book,
A Budget of Paradoxes, which catalogs the rejectamenta of the science of his day). She wants us to take these "outsider physicists" seriously, not as a kooky cultural phenomenon, but as people actually
doing science in a way that demands as much attention from mainstream science as folk art now claims from the elite art community… [a] beautifully written book…Wertheim shows us just how muddy the waters are on the border between what is classed as "legitimate" and what as "fringe."" –
American Scientist "Wertheim shows that there always have been passionate amateurs storming the gates of mainstream science, and she considers the profound need these outsiders have to define the world on their own terms." –
