Can that be Right?: Essays on Experiment, Evidence, and by A. Franklin

By A. Franklin

In this number of essays Allan Franklin defends the view that technological know-how presents us with wisdom in regards to the international that is in accordance with experimental proof and on reasoned and important dialogue. in brief, he argues that technological know-how is an inexpensive company.
He starts with precise stories of 4 episodes from the heritage of contemporary physics: (1) the early makes an attempt to realize gravity waves, (2) how the physics neighborhood determined proposed new effortless particle, 17-keV neutrino, didn't exist, (3) a chain of experiments on okay meson decay, and (4) the origins of the 5th strength speculation, a proposed amendment of Newton's legislation of common Gravitation.
The case reviews are then used to envision concerns corresponding to how discord among experimental effects is resolved, calibration of an experimental equipment and its valid use in validating an experimental consequence, and the way experimental effects supply average grounds for trust in either the reality of actual theories and within the life of the entities excited about these theories.
This ebook is a problem to the critics of technological know-how, either postmodern and constructivist, to supply convincing substitute causes of the episodes and concerns mentioned. it may be of curiosity to philosophers, historians, and sociologists of technology, and to scientists themselves.
