MIPS and GIPS are common metrics today as countless CPUs execute millions and billions of instructions per second ... a relationship between IPS and the clock speed of the CPU, which is measured ...

There are also interesting instructions like RDSEED, which generates a real random number. That can be useful but it takes many clock cycles to run, and like anything that purports to generate ...

What is the molecular clock? Levels of molecular variation could be used, in principle, to estimate divergence times, serving as evolutionary "clocks" that "tick" at different rates. Subsequent ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.

A clock with hands (an analogue clock) shows us the numbers 1-12. There are 24 hours in one day, so we measure time by splitting the day into two halves. The first 12 hours of the day, from ...

Sunrise alarm clocks mimic the gradually brightening light of the sun to ease you out of sleep. Think of it as a biological hack. “We evolved to align our sleep-wake cycles with the sun ...

Ekkehard Peik is a clock-maker. But instead of spending his days looking at tiny cogs and springs through a magnifying glass, the tools of his trade are powerful lasers, wires and, occasionally ...
