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 ...

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 ...

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 ...

Reviewed by Eric Estevez It's possible to calculate the standard error in MATLAB by running a one-line command. Standard ...

A DNA-based computer uses simple base-pairing to create AND and OR logic gates. 130 different double-stranded molecules later, the answer to a square root calculation popped out.

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, ...

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 ...
