[Fis] If always n>0 why we need log

[Sungchul Ji]

Hi Krassimir,


I think the main reason that we express 'information'  as a logarithmic function of the number of choices, n, may be because the human brain finds it easier to remember (and communicate and reason with)  10 than  10000000000, or 100 than 1000000000. . . . 00000, etc.


All the best.


Sung

Dear Sung,

A simple question:

If always n>0 why we need log in

I = -log_2(m/n) = - log_2 (m) + log_2(n)   (1)

Friendly greetings

Krassimir
