Advanced electromagnetism and vacuum physics by Patrick Cornille

By Patrick Cornille

This booklet is aimed toward a wide viewers: scientists, engineers, professors and scholars clever sufficient to maintain a severe stance every time faced with the chilling dogmas of latest physics. Readers will discover a tantalizing quantity of fabric calculated to nurture their suggestions and arouse their suspicion, to some extent no less than, at the so-called validity of state-of-the-art such a lot celebrated actual theories.
