My father, descended from Scottish refugees and a West Point graduate, was an officer in the Army Ordnance Corps. His frequently changing assignments took us from Washington, DC to Topeka,…

    The works of Wolfgang Paul, which led to the Paul trap, are based on investigations of the properties of electric and magnetic so called multipoles. A common magnet has two poles and is called a dipole, one with four poles, a quadrupole, one with six, a hexapole etc. Paul has shown that a…

Even very small deviations are of great principal importance and require the highest possible precision in the measurements. The laws of physics are directly or indirectly based on quantities such as mass, length, time…
