How do quartz watches keep time? Steve Mould gives a great demonstration explaining how they work. Quartz is piezoelectric, which means when it is deformed it generates an electrical signal. A quartz watch has a tiny quartz tuning fork that's been calibrated to vibrate at 215 cycles per second. This signal is fed through a series of 14 flip-flop circuits, each of which divides the frequency of the signal by 2. By the time the signal goes through the 14th flip-flop, the frequency is one cycle per second.

“The whole point of a programming language is to get the most out of the computer and the developer…This is why I like Python so much…few Python developers write code that is difficult to pass on to another developer.” With so much in tech so inherently complicated, that comment from Thomas Hatch, CTO and co-founder […]
In baseball, utility players often stay employed almost exclusively because of their versatility, their ability to slide effortlessly into a variety of needed roles and remain productive. Your current tech setup doesn’t need to work any differently — except that tech items are usually created to fulfill just one purpose. But if you want a […]
While all the downsides of stay-at-home orders and social distancing are evident, there are at least a few small silver linings to come out of all this.
