So you understand
3-dimensions – up and down, side to side, in and out. Now add in time as a
fourth dimension. That’s what you need to understand Einstein. He showed that
these dimensions, including time itself, can be stretched. Now Lisa Randall,
one of the world’s top Physics professors, has done research that shows that
the maths that describes our universe works better in many more dimensions.
String Theory seems to need an 11-dimensional universe. Lisa Randall’s own
theory has us on a 4-dimensional membrane surrounded by a fifth dimension in
which gravity can operate. It all sounds like Science Fiction but the theory
predicts the existence of particles that might appear soon in the CERN experiment
in Geneva. Lisa Randall is a great writer who explains difficult ideas with
great clarity. She uses stories and allegories to get the ideas across. Don’t
expect to understand it all at once but do let your mind be opened to the
cutting edge of theoretical research in Physics.

A Month in the Country by J L Carr
At only just over 100 pages long,
this novel is really an extended short story. It is set just after the First
World War and is about an ex-soldier who was wounded in the war. As part of his
recovery process, he is employed to travel to a village in the Yorkshire
countryside. His job is to chip away at the walls of the church to find a
hidden Medieval painting. In a way, this is a metaphor for him peeling away the
layers of mess in his life to find his old self. I loved the book. It is about
redemption and so is uplifting, but at the same time there is a sort of
nostalgic melancholy feel that has a part in English culture. I love both
aspects.
