It has just been announced that Alan Turing will be the face on the new £50 note.
We all know of his code breaking work at Bletchley Park in WW2 but many may not be aware that his mathematical genius resulted in the basis for modern computer coding and even A.I. as well as applying mathematics to plant biology to understand photosynthesis in plant growth.
A true giant of 20th century science.
