Calculator apps and handheld calculators are clunky, but Python's interactive mode easily recalls previous results for calculations. You can also scroll through and search input. Python offers basic ...

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 ...

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 ...

Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

Mastering quick square root calculations boosts maths exam performance. Speed and accuracy provide a significant advantage in algebra and geometry. Memorising key square roots and using mental math ...

One of various computer programming languages, C is the most basic and widely used language, likely because it gives maximum efficiency and control to programmers. The C language can be used for ...

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 ...

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, ...
