Abstract: I will discuss three problems in exoplanetary dynamics, all involving somewhat surprising behaviors of vectors tugging one another. (1) Binary-disk-star interaction leading to the formation of misaligned protoplanetary disks; (2) Gentle gravitational purturbation from a binary companion on planets leading to the formation misaligned hot Jupiters; (3) Extented transiting disks and rings around exoplanets.
