Today, I will talk about Katherine Johnson, a brilliant
mathematician who worked for NASA, and how her work
changed the perception of African-American women in the
fields of science and mathematics.
I chose this topic because I admire her courage, intelligence, and
perseverance in a time of extreme racial and gender
discrimination.
Who was Katherine Johnson?
Katherine Johnson was born in 1918 in West Virginia, USA.
From a very young age, she showed incredible talent in
mathematics.
She finished high school at the age of 14 and
graduated from college at 18 with degrees in mathematics and
French.
At that time, very few African-Americans, and even fewer
women, could access higher education, especially in scientific
fields.
After working as a teacher, she joined the National Advisory
Committee for Aeronautics (NACA), which later became NASA, in
1953.
She was part of a group of African-American women
mathematicians called the "West Area Computers," who
manually performed complex calculations for engineers.
Her major achievements at NASA
Katherine Johnson made major contributions to NASA’s space
missions.
One of her most famous achievements was calculating the
flight trajectory for Alan Shepard, the first American in
space, in 1961.
She also played a crucial role in the orbital mission of John
Glenn in 1962.
John Glenn personally asked for Katherine to check the flight
calculations before his mission.
He said, "If she says they’re
good, then I'm ready to go."....
