CHATS ON SCIENCE

By E.E.  SLOSSON

Author of “Creative Chemistry,” etc.

Dr. Slosson is nothing short of a prodigy.  He is a triple-starred scientist man who can bring down the highest flying scientific fact and tame it so that any of us can live with it and sometimes even love it.  He can make a fairy tale out of coal-tar dyes and a laboratory into a joyful playhouse while it continues functioning gloriously as a laboratory.  But to readers of “Creative Chemistry” it is wasting time to talk about Dr. Slosson’s style.

“Chats On Science,” which has just been published, is made up of eighty-five brief chapters or sections or periods, each complete in itself, dealing with a gorgeous variety of subjects.  They go from Popover Stars to Soda Water, from How Old Is Disease to Einstein in Words of One Syllable.  The reader can begin anywhere, but when he begins he will ultimately read the entire series.  It is good science and good reading.  It contains some of the best writing Dr. Slosson has ever done.

The Boston Transcript says:  “These ‘Chats’ are even more fascinating, were that possible, than ‘Creative Chemistry.’  They are more marvelous than the most marvelous of fairy tales ...  Even an adequate review could give little idea of the treasures of modern scientific knowledge ’Chats on Science’ contains ...  Dr. Slosson has, besides rare scientific knowledge, that gift of the gods—­imagination.”
