"Alles was überhaupt gedacht werden kann, kann klar gedacht werden. Alles was sich aussprechen läßt, läßt sich klar aussprechen." Translation: "What can be thought at all, can be thought clearly. What can be said, can be said clearly." - Ludwig Wittgenstein, Tractatus logico-philosophicus 4.116
"I think I can safely say that nobody understands quantum mechanics."
- Richard P. Feynman, “Probability and Uncertainty — the Quantum Mechanical View of Nature,” chapter 6, p. 129
Here you can find a selection of handwritten notes I took for some of my classes. These notes are not complete and I sometimes paraphrased, shortened or changed parts of the notes. Personal comments are written in grey.
