SEATTLE — When the public gets its first peek at Washington’s proposed new grade-by-grade math learning requirements, what they’ll find most surprising is how easy they are to understand, the ...

It is shown that certain conditional distributions, obtained by conditioning on a sufficient statistic, can be used to transform a set of random variables into a smaller set of random variables that ...

This is a preview. Log in through your library . Abstract A simple proof of Wiener's multiparameter ergodic theorem is given in this paper. At the same time it is shown that two of the hypotheses of ...

About twenty years ago, Olgur Celikbas attended a conference on algebra in Turkey. He and his then girlfriend, Ela Özçağlar, had recently graduated from college in Ankara; both had studied math. At ...

The chaos game uses a random number generator to draw a fractal. We start with an IFS that describes a fractal (some IFS are listed in the drop down menu - or if you want to input your own parameters, ...

We propose a method for reconstructing a probability density function (pdf) from a sample of an n-dimensional probability distribution. The method works by iteratively applying some simple ...

The quantum uncertainty principle stipulates that when one observable is predictable there must be some other observables that are unpredictable. The principle is viewed as holding the key to many ...
