   Format: MarkdownItexI am preparing slides for a 90 min lecture * _[[schreiber:Introduction to Higher Supergeometry|Introduction to Higher Supergeometry]]_ for the upcoming Durham Symposium _['Higher Structures in M-Theory'](http://www.maths.dur.ac.uk/lms/109/index.html)_. This is geared towards an audience of mathematically inclined string theorists. Accordingly, it starts with a lightning introduction to category theory and higher topos theory, from a perspective that should appeal to string theoretically minded people. We'll see how that works out... As usual, there is more in the slides than I plan to say out loud. Notably all of section 6) "_[Emergence of M-theory](https://ncatlab.org/schreiber/show/Introduction+to+Higher+Supergeometry#EmergenceOfMTheory)_" will not actually fit into the lecture, but might serve as material in a moonshine session for an inner circle. It's still a little rough here and there, but should be readable. Comments are welcome. (On my system, I go full screen at 133% resolution, then page-down keystrokes exactly give me a slide show. )
