How to explain nanoseconds?

One of the most amazing and informative talks i have ever saw on YouTube, where Grace Hopper (Rear Admiral of the US Navy) explains the value of a nanosecond. Grace Hopper, who is often refrerred to as ‘Amazing Grace‘ is one of the first real computer pioneers. She conceptualized the idea of machine-independent programming languages, which led to the development of COBOL, one of the first modern programming languages. Can you imagine that one of the Navy’s destroyer USS Hopper is named after her 🙂
