<i>The answer to the question Baker posed lay in a set of mathematical rules called an algorithm.</i><p>I never cease to be amazed just how low the math level is in our culture. And how acceptable it is to be publicly that math ignorant.<p><i>It was difficult, for example, to change the algorithm, which worked best in a single-threaded environment, into one that could take advantage of multi-core processors.</i><p>Aha, so the parallelized it!<p><i>"We have been able to reduce X-ray doses to previously unthinkable levels," said Professor Johan de Mey, head of the radiology department of University Hospital in Brussels, Belgium. That is opening up the benefits of CT scans to a wider variety of patients.</i><p>Great!<p>The terrible way in which this article explains what was done, is doubly ironic considering how it is an article about math and programming literally <i>saving lives</i>.
