David Lindley (born 4 December 1956)[1] is a British theoretical physicist and author.
From 1983 to 1986, he was a Research Fellow in the Theoretical Astrophysics Group at the Fermi National Accelerator Laboratory.
Lindley is known for writing entertaining scientific texts that show not only great knowledge of physics, but also a wit and understanding of what the layman can grasp.
In The End of Physics, Lindley challenged the assumption that string theorists might achieve a unified theory.
He contended that particle physics was in danger of becoming a branch of aesthetics, since these theories could be validated only by subjective criteria, such as elegance and beauty, rather than through experimentation.
