, who had been a family friend for many years who later encouraged Morawetz to pursue a PhD in mathematics. Morawetz says her father was influential in stimulating her interest in mathematics, but he wondered whether her studying mathematics would be wise (suggesting they might fight like the Bernoulli brothers).

Career

After earning her doctorate, Morawetz spent a year as a research associate at MIT before returning to work as a research associate at Courant Institute for five more years. During this time she had no teaching requirements and could focus purely on research.
She published work on a variety of topics in applied mathematics

 including viscocity, compressible fluids
and transonic flows. Turning to the mathematics of transonic flow, she showed that specially designed shockless airfoils develop shocks if they are perturbed even by a small amount. This discovery opened up the problem of developing a theory for a flow with shocks.
Subsequently the shocks she predicted mathematically have been experimentally observed
as air flows around the wing of a plane

In 1957 she became an assistant professor at Courant. At this point she began to work more closely with her colleagues publishing important joint papers with Peter Lax

At this point her research expanded to a variety of problems including papers on the Tricomi equation the nonrelatavistic wave equation including questions of decay and scattering.
