 ngs of the circle to 3-space up to isotopies. A classical way to distingui
 sh non-equivalent knots is to find a suitable invariant that takes differe
 nt values on the two given knots. In the same spirit\, given a smooth proj
 ective curve over a field\, we want to classify its embeddings to projecti
 ve 3-space up to a suitable notion of isotopy. We will explain how determi
 nantal representations of secant varieties give rise to invariants and dis
 cuss to which extent they completely classify embeddings up to our notion 
 of isotopy. A prominent role will be played by various variants of the wri
 the. This is joint work with Daniele Agostini.
