Mathematicians used “magic functions” to prove that two highly symmetric lattices solve a myriad of problems in eight- and 24-dimensional space. The points could be an infinite collection of electrons ...

I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those ...

Most engineering labs have digital oscilloscopes, but many engineers don’t fully explore their features. Among the more interesting features of a digital oscilloscope is its math channel, which can ...

A rule for creating a "y" output from an "x" input. For example, the y value of the function f(x) = 15x is 30 if x is 2. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires ...

Numbers like pi, e and phi often turn up in unexpected places in science and mathematics. Pascal's triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there's the ...

The human brain not only remembers who other people are, it also uses basic mathematical functions called basis functions to store information about how people interact — for example, how they work ...

Oscilloscope measurement parameters provide accurate measurements of acquired waveforms. Most digital oscilloscopes offer around twenty-five standard parameters like frequency, peak-to-peak amplitude, ...
