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 ...

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 ...

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 ...

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 ...

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, ...

While DNA-based computing may not be taking over silicon quite so soon, there is progress in the works. In a paper published by Small, researchers from the University of Rochester demonstrate a ...

DNA, the molecule of life, turns mathlete. Using the natural zipping and unzipping behavior of DNA strands, researchers at Caltech have developed a new and adaptable method for turning the molecules ...

Learning to calculate square roots quickly can make a huge difference in your maths exams. Whether you're doing algebra, geometry, or other topics, being fast and accurate with square roots gives you ...
