Work
The properties of atoms are determined by laws of quantum mechanics that say they can have only fixed energy levels and that electromagnetic radiation with certain frequencies is emitted or absorbed when there are transitions among different energy levels. Opportunities to study the properties and spectrums of atoms are improved if individual atoms can be isolated under constant conditions for longer periods. In the 1950s Wolfgang Paul developed a method for using electrical currents and electromagnetic fields to capture charged atoms—ions—in a trap.
Nobel Prizes and laureates
Six prizes were awarded for achievements that have conferred the greatest benefit to humankind. The 12 laureates' work and discoveries range from proteins' structures and machine learning to fighting for a world free of nuclear weapons.
