Ep 7. Singers, Short Circuits and Stones

Mission Unstoppable, season 4, episode 7, titled "Singers, Short Circuits and Stones," features three segments highlighting the diverse fields of science, engineering, and technology.

In the first segment, viewers meet award-winning scientist and singer, Dr. Tina R. Gentry. With a Ph.D. in neuroscience, Dr. Gentry uses her love for music to inspire young people to pursue careers in science. She visits a music school, where she teaches the students how sound waves work and how they affect our brains. The students then take part in a fun experiment to see how sound can manipulate shapes and patterns. Dr. Gentry's passion for science and music proves that pursuing multiple interests can lead to a fulfilling and successful career.

The second segment explores the world of engineering with a profile on Gitanjali Rao, an inventor, engineer, and TIME Magazine's Kid of the Year for 2020. At just 15-years-old, Rao has already developed several innovative solutions to real-world problems, such as a device that detects lead in drinking water and an app that helps detect cyberbullying. In this segment, Rao shares her latest invention, a device that detects and alerts users to potential electrical short circuits in their homes. Her passion for using technology to help others demonstrates how young people can make a big impact in the world of engineering.

The third segment delves into the world of geology with a look at how scientists study stones to learn about Earth's past. Host and former NASA engineer, Christine Darden, visits the Smithsonian National Museum of Natural History's Mineral and Gem Collection to learn about the different types of rocks and minerals. She meets with geologists who explain how they use rocks and minerals to study Earth's history, including the formation of the continents, the changing climate, and the evolution of life on Earth. The segment also explores the practical uses of rocks and minerals, such as in construction and jewelry making.

Overall, "Singers, Short Circuits and Stones" highlights the various ways in which science, technology, engineering, and math (STEM) can be used to make a positive impact on the world. Viewers are encouraged to pursue their interests and passions, and to be inspired by the talented individuals working in these fields.
