### Wittgenstein’s Picture Theory of Language as a Key to Modern Physics

#### Abstract

In this paper I pose the following question: how can we understand modern

physics, which is completely depend-ent on mathematics for its expression, and

where the mathematical symbolism has no obvious correspondence with our images

of physical objects? This problem is par-ticularly acute in quantum physics and

has stimulated a vast amount of discussion and research on what is called the

interpretation problem. I argue that Wittgenstein’s Tractatus provides a key to

understanding of such theories by explaining how a mathematical language can be

mean-ingful in a linguistic sense. I further argue that such an approach to the

interpretation problem corresponds closely to the position of quantum pioneer P.

A. M. Dirac, famous for his silence on the interpretation problem, which I

iden-tify as exactly the kind of silence Wittgenstein recommends in Tractatus, 7.
