The next time you use any navigation device, software or Google Maps thank Dr. Gladys West. Her contributions to the mathematical modeling of the shape of Earth, and her work on the development of the satellite models that were eventually incorporated into the Global Positioning System (GPS) technology. #BlackMastodon #BlackHistoryMonth
@LilHulkQ I think this is the 2nd block I have had to make on mastodon. I am impressed at the rarity.
