"[T]he author, whose work on nuclei is well known, describes a number of investigations carried out with his fog-chamber apparatus. The apparatus having been sufficiently improved, it was used for various experiments, including the growth of persistent nuclei, the production of water nuclei by evaporation, the results obtained when X-rays are allowed to strike the fog-chamber from different distances, the effect due to radium, &c. Other problems dealt with in the book are the distribution of colloidal nuclei and of ions in media other than air-water, the simultaneous variation of the nucleation and the ionization of the atmosphere of Providence, and the variations of the colloidal nucleation of dust-free air in course of time."

"When the history of the progress of physics in the United States during the late nineteenth and early twentieth century is written, the name of Carl Barus will occupy an important place."

"Carl Barus loved music, and composed about fifty compositions, among them a March to Pembrok Hall... and an Ode to the Steam Shovel, inspired by the daily noise outside his laboratory and was presented by him to President Faunce."

"While mental disturbances may provide individuals with an underlying sense of unease that seems necessary for sustained creative activity, these disturbances are not the only source for inner tension... chronic physical ailments may give someone a heightened sense of urgency to leave a mark on the world and achieve immortality through creative greatness."

"An arresting book that casts political science out the window and explains leadership through comparisons with chimpanzees, gorillas and orangutans."

"Useful for physicians who wish to understand alcoholism and the recovery process, and to gain anecdotal evidence of this process, which is presented by using the words of recovering alcoholics....Can be of great value to those many physicians faced with individual patients who are drinking too much."

"An excellent little book — highly informative, full of challenging and stimulating ideas, and teeming with shrewd clinical insights."

"Ludwig offers a unique integrative perspective which encompasses the clinical wisdom accrued through twenty-five years of experience as an alcoholism researcher and therapist....The book serves as an excellent primer for clinicians and recovering persons on a practical and multiperspective approach to alcoholism treatment."

"A thoroughly readable and rich introduction to...the process of recovery from alcoholism."

"An outstanding effort filled with important information for those who treat alcoholics, live with alcoholics, or who are alcoholics.... A significant contribution to the field, and all who deal with alcoholics would benefit from reading it."

"Ludwig also provides a brief, quite brilliant exposition and critique of the concept of an "authentic" self, noting that it is rooted in a male Victorian ethos and that it has been overshadowed by the more contemporary American notion of self-invention. Ludwig's beautifully written and intellectually provocative book is one of those rare works that offer fresh, profound insights, moving the reader to think probingly about his or her own life and self."

"Ludwig's book is outstanding. It pulls together a mound of pertinent data, much of it new, into coherent patterns...Throughout the book the reader is offered a wealth of insights and serious questions...Ludwig's development of a Creative Achievement Scale [is] a valued contribution in its own right, allowing researchers a comprehensive objective tool for scoring subjects' degree of achievement... Ludwig has cleared up much of the confusion and opinionated muddleheadedness... that has been attached to the topic and the thinking regarding a relationship between psychopathology and creativity."

"This is an excellent research report that should, once and for all, resolve senseless controversies about the correlation of creativity with psychopathology."

"Ludwig’s penetrating observations, though presented in a lighthearted and entertaining way, offer important insight into why humans have engaged in war throughout recorded history as well as suggesting how they might live together in peace."

"There not only should be far higher percentages of women in power, but they should be well represented at every level: crucial cabinet posts, ambassadorships, and the highest military ranks. I believe that countries then might not be so confrontational."

"Paranoia is naturally common among all kinds of rulers, especially tyrants and visionaries."

"Although humans and baboons may fight among themselves, dominate others, and keep harems, only humans have the ability to give pious excuses for what they do."

"People may choose to ignore their animal heritage by interpreting their behavior as divinely inspired, socially purposeful, or even self-serving, all of which they attribute to being human, but they masticate, fornicate, and procreate, much as chimps and do, so they should have little cause to get upset if they learn that they act like other primates when they politically agitate, debate, abdicate, placate, and administrate, too."

"There was no future and no past. The present was eternity."
