I invite you all to look at the problems (try to ignore solutions for now) for the 49th UNSW School Mathematics Competition in this issue. How many could you do, in three hours?

In my previous column, I looked at what we can learn of the mathematical achievements of Pythagoras and Theano. I relied in particular on an article by the Leningrad-based mathematician Leonid Zhmud, although I found his account maddeningly incomplete in places.

Detection of the arrival of important proteins at the cell surface is a problem of intense biological interest. Here we create an ideal model of the arrival of proteins at the cell membrane, as seen by a total internal reflection fluorescence microscope.

I'm no math genius. Mr Boxold always said math is about thinking up new ways of looking at things, even old problems. That's all I did.

Q1341 A lazy weather forecaster predicts that future maximum temperatures will be the average of the preceding two days maximum temperatures. The forecaster starts his forecast by noting that yesterday's maximum temperature was 23C and the day before it was 29C. What is the weather forecaster's long term maximum temperature forecast?
