Turning’s Sunflowers


Celebrate Alan Turing’s centenary year with an experiment!

This spring, we need your green fingers! Join Manchester Science Festival and MOSI (Museum of Science & Industry) for a mass planting of sunflowers as part of an experiment to solve the mathematical riddle that Turing worked on before his death in 1954.

Brighten up Manchester and the Nation, whilst helping mathematicians to explore Turing’s theories about plant growth. We need you to sow sunflower seeds in April and May, nurture the plants throughout the summer and when the sunflowers are fully grown we’ll be counting the number of spirals in the seed patterns in the sunflower heads. Don’t worry – expertise will be on hand to help count the seeds and you’ll be able to post your ‘spiral counts’ online.

The results will be announced during the Manchester Science Festival 2012 (27 Oct – 4 Nov), alongside a host of cultural events connected to Turing’s life and legacy, at MOSI, Manchester Museum and other cultural spaces.

Turing’s Sunflowers

You can never have enough sunflowers and a celebrate of this man is long overdue. Somehow it all just seems like it should be done.
