The person and the work
Biography
Cathleen Synge Morawetz was mathematician associated with Canada and the United States. She made major contributions to partial differential equations and the mathematics of transonic flow.
Morawetz showed why smooth airflow solutions can break down as an aircraft approaches the speed of sound. Together, these contributions connect algebra and functions, geometry and measurement, and calculus and change to the working problems, tools, and questions of the period.

Method, teaching, or application
Morawetz showed why smooth airflow solutions can break down as an aircraft approaches the speed of sound.
Why this matters
The larger lesson
Cathleen Synge Morawetz shows that mathematics grows through proof, calculation, observation, design, teaching, or careful records. The lasting lesson is that algebra and functions, geometry and measurement, and calculus and change can turn a difficult question into a method another person can inspect and reuse.

Key idea
An equation balances two descriptions
Cathleen Synge Morawetz’s work shows how symbols can represent an unknown quantity while preserving equality.
In 9x + 4 = 49, subtracting 4 and dividing by 9 gives x = 5.
Try it yourself
Solve the equation
Solve 9x + 4 = 49.
- Subtract 4 from both sides.
- Divide both sides by 9.
- Substitute the result to check.
Show the answer
x = 5.
Math at work
Engineers and architects use the same habits
Engineers and architects use algebra and functions to plan, compare, test, or communicate decisions. Cathleen Synge Morawetz’s work provides a historical example of that connection.
