Historical Note on Braid Theory
Emil Artin related the study of braids to group theory in the $1930$s.
In the $1960$s, Vladimir Igorevich Arnold pointed out the relevance of braid theory the theory of mappings.
Thus, if $n$ points are moved continuously in the plane back to their original positions, the motion can be interpreted as a braid.
Hence Arnold showed how the roots of a polynomial vary according to how the polynomial coefficients are varied.
Also in the $1930$s, James Waddell Alexander II established the close relationship between braid theory and knot theory.
This was then exploited in the $1980$s by Vaughan Frederick Randal Jones.
