A calculator processes numbers without caring that these numbers refer to items in our shopping, or the calculations involved in designing an airplane. Number without context is a remarkable abstraction that we learn as infants and
which has profoundly affected our world.
Our lives start, progress in complex ways, and are finally complete. So do tasks executed on a computer. Multimodal streams are a pervasive “type”, and even without fixing the context, have a rich structure. Developing this structure
leads to wide-ranging tools that have had award-winning impact on methodology in health care, finance, and computer technology.
