Background of Hidden Figures
The story of "Hidden Figures" highlights the professional lives of three African American women at NASA who played pivotal roles in the success of the U.S. space program during a time when segregation and gender discrimination were rampant.
- Katherine Johnson: A mathematician whose calculations of orbital mechanics were critical to the success of the first U.S. manned spaceflights.
- Dorothy Vaughan: A mathematician and computer programmer who led the first African American female group at NASA and became an expert in Fortran programming.
- Mary Jackson: An engineer who broke barriers in her field and became the first African American female engineer at NASA.
These women not only overcame personal and societal challenges but also made significant contributions to the field of aerospace engineering and mathematics.
The Mathematical Concepts at Play
The work done by these women involved various mathematical concepts that were critical in calculating trajectories, launch windows, and orbital mechanics. Understanding some of these concepts provides insight into the complexities and challenges they faced.
1. Orbital Mechanics
Orbital mechanics involves the motion of objects in space under the influence of gravitational forces. Some key principles include:
- Newton's Laws of Motion: These laws describe the relationship between a body and the forces acting upon it, laying the groundwork for predicting the motion of spacecraft.
- Kepler's Laws of Planetary Motion: These laws provide a framework for understanding how planets move in their orbits, which is essential for mission planning.
Katherine Johnson’s calculations were instrumental in applying these laws to real-world space missions.
2. Calculus and Differential Equations
Calculus is fundamental in understanding changes in motion and is used extensively in engineering and physics. Differential equations, which describe how a quantity changes in relation to another quantity, were crucial for:
- Predicting spacecraft trajectories
- Designing flight paths that minimized fuel consumption
The ability to solve complex equations allowed the women at NASA to optimize mission parameters.
3. Computer Programming
Dorothy Vaughan’s work with computer programming, particularly in Fortran, marked a significant shift in how calculations were performed at NASA. As computers began to replace manual calculations, her skills helped transition the workforce into a new era of technology.
- Fortran: A programming language used for numerical and scientific computing, which became a standard in engineering and scientific applications.
Vaughan's expertise in programming enabled her to lead her team and ensure they adapted to the evolving technological landscape.
