A warning to all who may use the coffee grinder in the SE lounge to make fine-grained coffee for use in an AeroPress: shaking the coffee grinder will blow the circuit breaker! It seems some of us don't realize that by applying rotating the axis of a spinning body, orthogonal to the plane of rotation, we are in fact applying a force against the angular momentum of said body. If this rotating device is powered by an electric motor, this causes the motor to draw more current to maintain its current speed. In short, don't shake the coffee grinder.
Also, I picked up the Annotated Turing again over the weekend, and read the first two chapters on number theory. I found this to be absolutely fascinating! Now, if you're already well versed in number theory, then these overviews may be redundant for you, but I thoroughly enjoyed it. Looking forward to what else is in this book.
