DESCRIPTION:There is a wide variety of structures that are equ
 ipped with a distance.  A familiar example is thre
 e-dimensional Euclidean space: here the distance i
 s the length of the straight line segment joining 
 two points. In this example there is an additional
  feature: the presence of vector addition and scal
 ar multiplication. There are examples\, however\, 
 that do not possess such additional features\, and
  it is an important question to determine whether 
 such arbitrary structures can be embedded into one
 s with a vector structure like Euclidean space. Th
 is has consequences for large data\, algorithms\, 
 compressed sensing\, etc.\, some of which have eme
 rged in unexpected and surprising ways.
