Axel Christian Klixbull Jorgensen was a "Polyhistor,"one of the very few in the highly specialized science of our time.His interests and contributions in ch- istry covered the whole Periodic Table.This statement demonstrates the breadth of his interests, however, it also sheds light on the constraints of chemistry which deals with a large, yet limited number of elements. It is not surprising that Jorgensen went beyond these limits, exploring the probable or plausible ch- istry of yet unknown elements and elementary particles such as quarks. Even chemistry itself did not place rigid limits on...
