Please don’t give me a CURTA!

Designed by Curt Karzstark while held in Buchenwald concentration camp. This wonderful cross between a dalek and pepper mill is one of the the most powerfully compact mechanical computers in the world! This four-banger pepper mill can also perform square root calculation with some finessing. To add two numbers together, each must be entered on the […]

This seemingly simple accomplishment (by today’s standard) set the groundwork for all future computer processing and algorithms. Turing never built the machine as the importance of this achievement was in conceiving the theoretical […]

thefuture of the present

What does it feel like to be present? How do we live in the moment? And here is another way to look at time. Still the same iconic round face and the central wheel turning. But this isn’t a daily once around the dial kind of clock. Nope! This clock goes around once a year! […]
