Math Champions

The woman who made GPS possible has taken her final journey.

Dr. Gladys West died Saturday at 95. She was the mathematician who built the model of Earth that makes GPS work.

She was born on a Virginia farm in 1930, the daughter of sharecroppers. She picked to***co as a child and walked miles to a one-room school. She made herself valedictorian, earned a full scholarship, and stacked degrees in math until the Navy hired her in 1956.

At the Naval Proving Ground, she programmed computers the size of rooms using punch cards and flow charts. She calculated the shape of Earth, the real shape, lumpy and irregular, precise enough that satellites could use it to tell you exactly where you are at any moment. That work became GPS.

She retired after 42 years. Then she had a stroke at 70, recovered, and earned a PhD from Virginia Tech.

For most of her life, no one knew her name. Her work was classified. She didn't even tell her kids. Then a friend asked for a bio in 2017 and the story came out. Hidden figure, finally seen.

She never used GPS herself. Preferred paper maps. "If I can see the road and see where it turns," she said, "I am more sure."

She spent her whole life making sure the rest of us never had to wonder.

Rest in peace, Dr. West.

I recently asked a friend if we would still have quality teachers in Physical Classrooms in the next 10 years.

The demand for online tutors is exploding!

Calendars of online tutors are packed.
Yet, there’s a fresh surge of students needing support daily.

A friend shared that her monthly salary as a classroom teacher equals what she earns for a tutoring session twice weekly.

Tech-savvy educators who can leverage digital tools are going online in large droves.

This points to a critical point for schools.👇

Beyond basic remuneration, do we have other psychosocial features in place to retain great teachers?

Otherwise, the online market is wide open and waiting.

In the next 10 years, will our physical classrooms still be filled with quality teachers, or will all the BEST talents have migrated online?

The biggest joke on earth is computer asking us to verify that we're humans 😂
