That's Maths II

This collection of mathematical articles covers a broad range of
delightful topics in pure and applied mathematics. It is written in
an expository style, making it accessible to everyone with a general
interest in mathematics.
There are articles about renowned mathematicians and about the history of
some key ideas in maths. The importance of mathematics in the modern world
is illustrated by applications in engineering, technology, astronomy,
music and the visual arts.
Reading mathematics is best done in small steps. The articles are
all short, and they can be read in arbitrary order. Some articles
are purely descriptive. Others go deeper and are at a more advanced
mathematical level.
Approximately half the articles have appeared in the author's regular
column "That's Maths" in The Irish Times. Others have been posted to
his mathematical blog, thatsmaths.com. All articles have been fully
revised for this book. This is the second collection under the rubric
"That's Maths". The first collection, published in 2016, was very
favourably reviewed.
The author has succeeded in bringing out the amazing beauty of mathematics
and its utility in so many areas of our lives. The book should be
appreciated by anyone with an interest in mathematics and science. In
particular, teachers of these subjects, at both school and university
level, should find a wealth of material to supplement and invigorate
their classes.
