Universities, libraries, funders ... need to build a system that is community-led and managed, and which works to further research... This should involve active support for federated open infrastructuresβ

Joyful Mdhluli woke up one day and realized she didnβt want to stay in academia. She now works at a nonprofit in Cape Town, South Africa, where she coordinates major projects that use astronomy for social benefit. #whatcanphysicistsdo #physics

Website titled The Science Playground, subtitle a list of interesting links. There are six thumbnails visible below, sorted into a grid. Many have basic planet images and orbit lines, showing off simulations. The few shown with titles are: "Gravity Simulator - Huffman", "Black Hole Explorer", and "Orbit". There are search options and dropdowns on the left hand side, one of which is set to "gravity"
Looking for a Gravity Simulator to play around with?
Well, here's a list of interesting ones I pulled together.

Pictured: Gladys West-the mathematical and computer programming expert who created an accurate model of the Earth, which was the foundation for GPS. She was inducted into the US Air Force Hall of Fame, one of the highest honors offered by the Air Force.
Most of us have used Global Positioning System (GPS) for navigation & we can thank Gladys West for creating the foundation for GPS.
She used her mathematical & programming expertise to invent an accurate model of the Earth.
She was inducted into the US Air Force Hall of Fame.

Not my usual research topic, but a bit of fun for a local SFF convention :) I analysed the astrophysics of the Legend of Zelda games -- using the same techniques real astronomers use! Good fun, educational, and the audience loved it!
