The quest for the Northern Lights
The Northern Lights is a well researched biographical tale of the Norwegian physicist and genius Kristian Birkeland, whose life was spent exclusively in pursuit of the scientific goal of understanding solar-terrestrial relationships. The author, Lucy Jago, has turned his life into a highly compelling story that keeps the reader interested, and also learning, as the […]

Ultrafast cameras streak ahead
According to the old adage, “a picture paints a thousand words”. And in many scientific disciplines ultrahigh-speed imaging is the only reliable way to visualize the countless physical and mechanical processes that occur on microsecond timescales. Such processes include ballistics, the propagation of cracks in materials, flame fronts in combustion research, the generation of shock […]
A new twist for magnetic moments
First discovered in experiments on ions in the early 1920s, the understanding of magnetic moments played a central role in theoretical physics during the 20th century. In the case of free electrons, comparisons between theory and experiments of ever-increasing accuracy continue to provide one of the most significant tests of the theory of quantum electrodynamics.
