DNA holds the code for all living things – and now it can solve square-root problems too. Researchers have built the largest and most sophisticated system yet that performs calculations using DNA. The ...

Years ago, no math education was complete without understanding how to compute a square root. Today, you are probably just reaching for a calculator, or if you are writing a program, you’ll probably ...

Somewhere around middle school, you learned about squaring numbers and the inverse, finding the square root of a number, but a little reminder can't hurt. You square a number when you multiply it by ...

Square-root-calculating circuits find wide use in instrumentation and measurement systems for such tasks as calculating the rms (root-mean-square) value of an arbitrary waveform, for example. Hence, ...
