Q. Why do we need static charts and models when the Internet is full of interactive ones?

        Details of answer;
      A printed 2-D chart is completely random access while you see it, while an computer based interactive chart is equally random access at each step, but can reveal an entirely new chart at a click, with multiple choices at each screen, accessed only by electronic means, while printed charts, while ubiquitous, each carry limited data.
      Some alternative 2-D element periodic tables (usually spiral) have been developed as an improvement for learning for new students. These, in a continuous unidirectional periodic spiral of element data blocks, generally have an elliptical shape, with each block representing a different chemical element;
              The blocks are positioned so that chemical elements in a Period are in a single spiral loop, and each successive Period has a larger circumference than a preceding Period;
and      

      Static charts are being supplanted in many academic and lab settings by computer based tables, as so much different data is so well and so quickly displayed interactively.
