Roots are the reverse of powers. For example, a square root is the reverse of a square number. So \(5^2 = 25\) and \(\sqrt{25} = 5\) A cube root is the reverse of a cube number. Write 40 as a product ...

The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

[MindYourDecisions] presents a Babylonian tablet dating back to around 1800 BC that shows that the hypotenuse of a unit square is the square root of two or 1.41421. How did they know that? We don’t ...

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, ...

Legendary investor Sir John Templeton once said that If you want to have a better performance than the crowd, you must do things differently from the crowd. Templeton, who is regarded as the greatest ...

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 ...
