I have a new story published on my Across the Universe blog over at The Guardian.

"Isaac Newton's belief in spirits and alchemy may have been essential to achieving his towering scientific achievement: gravity. A new science and arts festival begins this weekend to explore this complex man

Hot on the heels of Isaac Newton's apple appearing at the Paralympics comes a new celebration of his life and achievements. The Gravity Fields Festival begins on Friday in Grantham, Lincolnshire. For eight days, Newton's life and times will be commemorated by more than 100 events around the town, during what could become a biennial event.

It is true that he was capable of the most precise and logical thought it is possible for a human to achieve: his three years of obsessive work that gave birth to the Principia, containing his theory of gravity, stand as the greatest achievement in science.
