Query: Whitehead doubling persists   The operation of (untwisted) Whitehead doubling trivializes the Alexander
module of a knot (and consequently, all known abelian invariants), and converts
knots to topologically slice ones. In this note we show that Whitehead doubling
does not trivialize the rational function that equals to the 2-loop part of the
Kontsevich integral.
