DESCRIPTION:To make planets\, stars and supermassive black holes\, one mus
 t rapidly accrete material onto central objects. But the tiniest tangentia
 l motion combined with angular momentum conservation sends material into o
 rbit\, rather than accreting. Since work at the IoA in the 1970s we have u
 nderstood that Nature solves the angular momentum problem by forming accre
 tion discs\, but the angular momentum transport mechanism remains unclear.
  The past 10 years have given us spectacular resolved observations of disc
 s around both young and old stars\, bringing fresh clues. In this talk I
 ’ll explain how pairing 3D simulations with observations helps us solve 
 the problem of accretion\, revealing how stars and planets form\, black ho
 les grow and how accretion powers tidal disruption events.
