It was the "modulo" I had trouble with (the idea of quotient spaces). I understood well how kernels corresponded to cycles (people on IRC made me do lots of calculations with chain complexes both in Z/2 and R), and had some idea of groups (or, at least, of when something is a semigroup and not a group...) but didn't have an internal feeling of what quotient groups were.
- jvvw 6y agoDo you grok equivalence classes because quotients (of anything) are basically sets of equivalence classes? And on the parenting front, luckily you start with a baby not a ten year old so you have lots of chance to grow as a parent before making those sorts of decisions - a lot of parenting is deciding when to be directive/non-directive and when to take charge based on your superior understanding of the world (not letting your toddler walk into the road!) and when to let them learn from their own mistakes.
