You've probably heard of the term "nanosecond", which is a billionth of a second. But perhaps you, like me, have trouble getting your mind around anything that says "billionth". But leave it to a lady to really explain something in a manner I -- and you -- can easily understand. Here is a short video wherein Admiral Grace Hopper explains a "nanosecond" using a piece of wire. Interesting. Take a look.
