I am delighted to report that the IMA and the National STEM Centre have made all twelve issues of *iSquared Magazine* available as PDFs for free download for the first time. The magazine was produced as a print-only publication by Sarah Shepherd from 2007-10.

After she died, I wrote an obituary for Sarah in the *LMS Newsletter*, in which I told the story of how the idea for iSquared came about:

She once told me that before her degree she would visit her local library and, in the absence of a mathematics magazine aimed at sixth-formers, would look through back copies of New Scientist for articles about mathematics. When she began her PhD, realising the ’mathematics magazine’ she had been longing for still didn’t exist, she decided to set it up.

In her first editorial she wrote,

Many people are unaware that maths is more than just abstract concepts, inaccessible to all but those with a university education in the subject. In fact, mathematics can be appreciated by everyone. The past few decades have seen maths being used in numerous innovative real-world situations.

The National STEM Centre eLibrary entry gives and indication of the content:

Each magazine contains regular news items, a mathematical histories feature, puzzles, book reviews and the life of a great mathematician as well as special articles on cryptography, crowd dynamics, string theory, neuroscience, aerodynamics, mathematical finance, environmental modelling, operational research, public transportation, relativity, game theory and medical imaging, to name just a few of the topics.

Please read the magazines and share the link with others.
