He entered the University of Lund in the autumn of 1873, and it is fair to say that he never left. He received his doctorate in mathematics from that institute in 1879 and was appointed a teacher of mathematics there in 1881. But in 1876 Rydberg was also appointed as a teaching assistant at Lund s physics institute. His experimental study on friction electricity led to a position as a teacher of physics in 1882. 

As a physicist and mathematician, Rydberg was driven by a desire to understand the basic physical laws behind the Periodic Table. He set out to

Many scientists use spectroscopy on a daily basis to gain insight into the structure of molecules or the concentration of atoms or molecules in a sample. The chemist uses radio waves and infrared radiation to determine the structure of a new molecule. The geologist uses ultraviolet radiation to determine the concentration of a particular element in a rock or mineral. The microbiologist uses fluorescence measurements to determine the concentration of bacteria in solution, see also Rydberg, Johannes.
