I couldn’t agree more with Siân, it’s always a pleasure listening to Simon Singh as it was listening to all the other great presentations at the **February TM Maths Icons Conference**. An amazing day – thank you so much **@TMMathsIcons**.

A reminder of Simon Singh’s **Parallel** and **Top-Top Set Maths Project**:

Not a conventional competition, but to challenge your able mathematicians, try **Parallel from Simon Singh**. All materials and resources are completely free and **teachers** will have access to all the student scores from the Parallelograms which are automatically marked.

Students earn points depending on their percentage score on each Parallelogram, which in turn earns mathematical badges. Even before you create an account Even without an account, you can get a taste of what we offer by just clicking on the **Parallelograms on the left**. Have a look at this parallelogram on **Pie Charts and Speed Reading** for example.

The references to Simon’s book The Simpsons and Their Mathematical Secrets was a reminder of all the brilliant Maths hidden in The Simpsons. Information for teachers on the book is available, including a **PowerPoint presentation for teachers** Simon Singh has created, notes are given with the slides.

It was also a reminder that back in 2014 I was honoured to feature a post featuring **answers by Simon Singh** to my questions.

I enjoyed all the sessions, including Robert Southern on Graphical Transformations.

My own presentation was on the use of **Colour in Mathematics** and all the slides and some further links referenced in the slides are available on a **dedicated page**.

The puzzle at the beginning of the post which apparently Bart got before the rather more nerdy Lisa featured in the episode **Lisa the Simpson**.
