There is one killer slide at 12:20 comparing the gross sales of low-IP-protection industries with those of films and books and music. If you want to know more, or if you prefer text, the Ready To Share project website should give you all the data you crave on the subject."
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
