The public parts of my notebook.
But Wittgenstein was “interested in everything,” and he engaged his students in a sort of “project-based learning” that wouldn’t be out of place in the best elementary classrooms today. They designed steam engines and buildings together, and built models of them; dissected animals; examined things with a microscope Wittgenstein brought from Vienna; read literature; learned constellations lying under the night sky; and took trips to Vienna, where they stayed at a school run by his sister Hermine. Just to get to the train required a twelve-mile hike through the mountainous forest around Trattenbach; on the return trip, the students made this hike after midnight. On the way, Wittgenstein would ask them the names they’d learned of the plants in the forest. In Vienna they would discuss the architectural styles of the buildings they visited and look for examples of the machines they had modelled.
