Physics
Crowther, James Arnold. 539 C8gi
Ions, electrons and ionizing radiations. 1919. Longmans.
"References." p.272.
"Is not a popular exposition of the 'new Physics' nor is it a compendious synopsis of
the whole subject. . .Is intended solely as a text-book from which students who have been
grounded in the more elementary portions of Physics might obtain a systematic knowledge
of its latest developments." Preface.
Contains a little of the material in the author's "Molecular physics," but is fuller,
more technical, and pays greater attention to apparatus and technique.
Crowther, James Arnold. 530 C89
Manual of physics. 1919. Frowde. (Oxford medical publications.)
Prepared primarily for British first year medical students in an attempt to produce
a text-book which shall be "satisfactory from a scientific point of view without being
too elaborate, and elementary without being childish." Preface.
Crowther, James Arnold. 539 C89
Molecular physics. Ed.2. 1919. Churchill. (Text-books of chemical
research and engineering.)
"Bibliography," p.186-187.
Author is demonstrator in physics at the Cavendish Laboratory, Cambridge, and
thus closely in touch with the work of Sir J. J. Thomson. Though well up to date regarding
recent developments, the book is characterized by temperate presentation.
"The author is eager to discriminate between the known and the conjectural. He is
as careful to distinguish where the solid grounds of experiment end, as he is to indicate
the pleasant fields in which precarious speculation may harmlessly disport itself, or the
still more dangerous quagmires ready to engulf the indiscreet efforts of undisciplined
imagination." Engineering, 1919.
