After seeing an exhibit of an old relay-based computer as a kid, [Simon] was inspired to build a simple two-relay latching circuit. Since then, he’s been fascinated by how relays can function to do ...

Finding cube root in a quick manner can be very important for the fast Calculations in any competitive exam. Let us see how to find the cube root of a number? The cube root of a number is another ...

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, ...

To find the cube root of a number, we have to find out which number when multiplied by itself twice gives that number. This is the same as trying to find out the length of the side of a cube when you ...

Researchers at the University of Rochester in New York have developed a DNA computer that’s capable of performing square root calculations of numbers all the way up to 900. It’s an impressive ...

A new DNA computer calculates square roots of perfect squares up to 900. Like quantum computers, DNA computers are an exciting frontier of post-silicon computing. Where previous examples were up to 4 ...
