The internet was born out of research for the U.S. military on how to create a network which could withstand a nuclear attack. The instructions for how the internet gets your data from your computer in Peoria to a server in San Francisco are still based on that early 1960s research. Recent research shows that the internet has retained this resiliency in the face of network damage.
It bugs me that some of my best writing is on Facebook where only a few friends will see it. So let me elevate this comment, which was in response to my friend Charlie. He started out with this question, regarding the particle/wave duality of light:
You can measure a wave and you can measure a particle - how can something be both?
My reply:
You just have to squint at it at the right angle.
