We’ve got a great show lined up for you today as we take another look at some of our favorite interviews from last season. We’ll give you an encore of Shawn’s interview with an acoustical engineer. She’ll talk about how she uses tools—plus her math and physics skills—to control the sound in buildings. And finally, we’ll bring back Helena’s visit with a home health aide and learn how she assists her elderly clients with their daily needs. She makes quite a difference in their lives! Drones are becoming more popular every day. So we’re going to show you Shawn’s interview with a drone pilot and see how unmanned aerial vehicles are replacing helicopters and making it much simpler to shoot aerial footage for TV shows.
