... The technique of electron resonance has been employed for some time now not only to observe the state and presence of normal paramagnetic atoms but also to study organic free radicals. Until recently the work on free radicals had been confined to known stable compounds. Measurements are outlined her ...

... à Term comes from the ancient Greek city of Magnesia, at which many natural magnets were found. We now refer to these natural magnets as lodestones (also spelled loadstone; lode means to lead or to attract) which contain magnetite, a natural magnetic material Fe3O4. à Pliny the Elder (23-79 AD Roman ...
