DESCRIPTION:There is a wide variety of structures that are equipped with a
  distance.  A familiar example is three-dimensional Euclidean space: here 
 the distance is the length of the straight line segment joining two points
 . In this example there is an additional feature: the presence of vector a
 ddition and scalar 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 ones with
  a vector structure like Euclidean space. This has consequences for large 
 data\, algorithms\, compressed sensing\, etc.\, some of which have emerged
  in unexpected and surprising ways.
