Issue 44 of Plus is now out!  - http://plus.maths.org


What's the risk of climate change or passive smoking? Why do penguins 
rotate their eggs? Is nature lazy? And how did we evolve the maths behind 
these questions? Find some answers in this political, psychological, 
philosophical and physical issue of Plus, and do some real sums with our 
interactive checker board.

Teacher package: Mathematical modelling

This issue carries the second installment of a new feature in Plus: the 
teacher package bringing together all Plus articles about a particular 
subject from the UK National Curriculum. This time we look at mathematical 
modelling. We've classified the articles according to the depth of the 
maths content, so teachers and students can take their pick from articles 
that contain explicit calculations and proofs, those that give the bigger 
picture, and those that have explicit maths, but require the reader to fill 
in some gaps. Have a look!
