In September 2013, I gave 6 hours of lectures on Effective Field Theory and Quantum Gravity at the Saalberg Summer School on Theoretical Physics. I recorded the lectures and am posting the notes and videos here. The pdf notes each cover a 1.5 hour block, while I have broken the recorded lectures into sub-units of about 45 minutes each.

**Lecture 1** Notes. Why do quantum calculations work?, Ideas of Effective Field Theory, Linear sigma model, Integrating out a heavy field, Matching

**Lecture 1a** Video

**Lecture 1b** Video

**Lecture 2** Notes Matching (cont.), Power counting, Heat kernel, Background field method, Low energy QCD

**Lecture 2a** Video

**Lecture 2b** Video

**Lecture 3** Notes Other EFTs, General Relativity as an EFT, Quantization, Feynman rules, Quantum correction to Newton’s potential

**Lecture 3a** Video

**Lecture 3b** Video

**Lecture 4** Notes Graviton scattering, metric corrections, limits to the EFT, gravity as the square of a gauge theory, cosmology, running couplings (or lack thereof)

**Lecture 4a** Video

**Lecture 4b** Video
