\nKnots have an extremely long history. In current times most people inter
ested in knots are either sailors or climbers or knitters or surgeons or m
athematicians. The classic mathematical theory of knots is to do with the
topology of closed loops\, so that shape is unimportant. More recently a s
mall literature on the geometric theory of knots has arisen\, where unders
tanding certain idealised optimal shapes is everything. In parallel there
is a (small) literature concerning the mechanics of real knots\, where fri
ction is everything. I will present some results of my own work on knots s
tarting with simple mathematical models of the mechanics of knots\, then p
assing to rather abstract mathematics of idealised optimal geometric shape
s\, and then returning to the reality of experimental data obtained by the
group of Prof. P. Reis.\n\nBio:\nBachelor in Mathematics\, University of

ied mathematics\, including physical knot theory\, but primarily in the mu
lti-scale mathematical modelling of DNA.
