2. It was no less a figure than Professor Derek de Solla Price, in his Little Science, Big Science , who expressed one perspective on science in the following terms: "We may define a man's solidness as the logarithm of his life's score of papers.
3. Most authors have usually opted to study either price changes ( F t +1; - F t ) or the change in the logarithm of prices (ln F t +1; - ln F t ), which can be rewritten as the logarithm of the price relative, that is, ln ( F t +1; /F t ).
4. Hence, the use of the change in the logarithm of prices implicitly assumes that F t is the sum invested.
5. Figure 11.4 shows what happens if we take a logarithm of every number in figure 11.1; the resulting shape is shown in figure 11.5.

11. For each change in the value of the MMI, Finnerty and Park (1987) regressed the natural logarithm of S t /S t -1; on the immediately preceding natural logarithm of F t /F t -l , where S t is the spot value of the index at time t and F t is the value of the future on the MM.I at time t .
12. These were eventually formalized in the Weber-Fechner law which reported a quantitative relationship between stimulus and subjective experience, the sensation increasing in proportion to the logarithm of the magnitude of the physical stimulus.
