1. Introduction

  2. Simplicity at various levels

    1. WCW level: a generalization of Einstein's geometrization program to entire quantum physics

    2. Space-time level: many-sheeted space-time and emergence of classical fields and GRT space-time

    3. Imbedding space level

  3. Some questions about TGD

    1. In what aspects TGD extends other theory/theories of physics?

    2. In what sense TGD is simplification/extension of existing theory?

    3. What is the hypothetical applicability of the extension - in energies, sizes, masses etc?

    4. What is the leading correction/contribution to physical effects due to TGD onto particles, interactions, gravitation, cosmology?
