In 1904 she began her long service at Wellesley College, beginning as an assistant in mathematics and becoming a full professor.
[2] In 1933 Young contributed an article to American Mathematical Monthly on a configuration of triangles associated with a parabola π.
The corresponding orthocenters, circumcenters, centroids, and centers of the nine-point circle are approached using projective properties of the triangles.
She identified the locus as a hyperbolic cylinder through use of a third parallel midway between the others that is the projective harmonic conjugate of a line at infinity.
The problem was to show that the double points of these involutions are three pairs of opposite vertices of a complete quadrilateral.
[7] Young proposed construction of a strophoid: Form triangle AOB from a fixed point A and a variable B on circle centered at O.
