56. Dr. Sinenhlanhla Sikhosana-Astronomer & Astrophysicist; PhD in Applied Mathematics

Ordinarily Extraordinary - Conversations with women in STEM

Sinenhlanhla Sikhosana recently received her PhD in Applied Mathematics with a research focus in Astrophysics. She also holds Bachelor's and Masters degrees in Applied Mathematics and Pure Physics. As a young girl in a small village in South Africa, Sinenhlanhla had big dreams, but few role models. She did, however, have a grandmother and a mother that encouraged her to think outside their traditions and encouraged her to pursue her dreams.
Episode Notes

Have you ever wondered what an astrophysicist is or what you do for a job as an astronomer? What kind of education do you need for this job? Where do you work? What do you study? Sinenhlanhla shares her experiences as an astrophysicist and astronomer is South Africa. She grew up in a small village where women traditionally stay at home to take care of the family, but she had a grandmother and mother who encouraged her to follow her passion and dreams and make her own way.

As a recent PhD recipient, not only does Sinenhlanhla work as an astrophysicist and astronomer, but she also focuses on outreach so that other girls, especially girls in small villages, can see themselves represented through her.

In addition to talking about astrophysics and astronomy, we also discuss the challenges of being female and wanting to have a family and still pursue a career in academia. We discussion challenges of schooling in South Africa and so many other topics on this podcast.

Acronyms, Definitions, and Fact Check

Cosmology - a branch of astronomy concerned with the study of the origin and chronology of the universe. Physical cosmology is the study of the universe's origin, its large-scale structures and dynamics, and the ultimate fate of the universe, including the laws of science that govern these areas. (Wikipedia)

Astrophysics - the branch of astronomy concerned with the physical nature of stars and other celestial bodies, and the application of the laws and theories of physics to the interpretation of astronomical observations. (Oxford Languages)

Astronomy - a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. (Wikipedia)

Supernova - the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. (https://spaceplace.nasa.gov/supernova/en/)
