I’ve been studying some physics for a while and decided to write solution manuals for reference in case I forget the approach to a problem later. They’re lazily written, hence some solutions might be incomplete, incorrect or have illogical statements. Here’s what I’ve compiled so far:

• Tom Lancaster et. al. - Quantum Field Theory for the Gifted Amateur
• Bernard F. Schutz - A First Course in General Relativity
• Ramamurti Shankar - Principles of Quantum Mechanics
• T. Padmanabhan - Gravitation: Foundations and Frontiers

I’ve also attended some conferences on mathematics and written down some (very incomplete) notes from the talks, and studied some areas with Vyn from freenode’s ##math:

• Hopf Algebras and Combinatorics Lecture Notes (with Vyn)
• Cycle Polynomial of Permutation Groups (with Vyn)
• Heaps and Applications by K. N. Raghavan
