An MPRI confession

Now I’m a teacher andunderstandwhy teachers teach like that:

• They enjoyresearchmore thanteaching

• They arepromotedbased onresearchnotteaching

• They arehereto findPhD studentsto do more research

• They areshort on timeso...

• Making complicated things understandabletakes time

• It’s to recycle existing slides about stuff you know!

(28)

Will this class be any different?

• Lessincomprehensible theoryand moreshallow practice

• The project can befun(hopefully)

• The class material/structure is probablynot perfect, sorry...

• OK I won’t try to hide it: we are hiring!

• ... but most of this class isn’tso relatedto what I do, so...
