The video below explores how technology was used to capture the first images of a black hole.
Technology surrounds us in everyday life and helps us learn about phenomenon millions of miles away. As we explore historical records, the technology of the past may seem too simple to be technology when you're used to thinking about on the amazing technology we hear about regularly (large hadron collider, cameras that can capture black holes, Mars rovers) but technological advancement is only possible by building on humbler beginnings.
Research works this way too, which is one reason of many that accurate citations are so important. Speaking of research and technology, this research guide also relies on humbler beginnings: several technological innovations work together to make this guide possible.
