Undecidabilty, Quantum Mechanics and Chaos

Sala 8.2.16, Ciências ULisboa

Por Álvaro Perales Eceiza (Universidad de Alcalá).

In this 8-hour course with contents of physics, mathematics and philosophy of science, we will study the theories that a priori suppose a limit to the knowledge we can acquire about nature and the predictions of its future behavior, focusing on Undecidability (Gödel, Turing) and its manifestations in physics.

Contents of the course:

  1. Introduction
    Can we know everything with science? Determinism, Reductionism, Predictability, Emergence
  2. Chaos and Quantum Mechanics
    Chaos. Nonlinear equations and sensitivity to initial conditions. Examples
    QM. Uncertainty principle. Wave function and Schördinger equation. Superposition and entanglement. Measurement problem and interpretations of QM
  3. Undecidability in Mathematics
    Axiomatic systems: From Euclid to Principia Mathematica
    K. Gödel: Undecidability and Incompleteness in Maths
    A. Turing. Universal Turing machine and halting problem
    Algorithmic Information Theory. Kolmogorov-Chaitin Complexity
    Extensions to other mathematical systems
  4. Undecidability in Physics
    Undecidability in the physical world?
    Mappings from mathematical systems to physical systems
    Some results of undecidability in classical and quantum systems
  5. Summary, open problems and discussion
    Are there fundamental limits to knowledge about nature?
