Thirty Years' War The Thirty Years' War[l] took place largely within the Holy Roman Empire from 1618 to 1648. One of the most destructive wars in European history, it caused an estimated 4.5 to 8 million deaths, while some areas of Germany experienced population declines of over 50%. Related conflicts include the Eight...

Binary – base 2. We’re used to decimal, which is base 10, meaning we can use 0 through 9. In base 2, or binary, we use 0-1. The reason why computers use binary is that people tried and failed to make stable base 10 vacuum tubes back in the day. It’s much easier to represent just two possible states instead of 10. With ...
