Binary

Binary logic and binary math allowed the digital revolution. It didn't have to be this way. There are still analog computers and computers could make decisions between three choices at a time instead of two, but it seems uneconomic right now. A/D and D/A (Analog to digital and vice-versa) is convenient enough and quick enough that we have learned to ignore the difference between the two kinds of data. This pattern of yes-no choices (bits) has not made our world black and white. As choices have broken down and simplified, patterns have compensated by finding new intricacies.
