 hoo\n\nAffiliation:\n University of Waterloo\n\nRoom:\n MC 5501\n\nABSTRAC
 T:\n\nGiven four lines in 3-space\, can you find a fifth line that\ninters
 ects the other four? How many?\n\nThis is the smallest non-trivial examp
 le of a \"Schubert problem\". The\nanswer\, in this case\, is not hard to 
 compute: there are two such\nlines. Generalizations of this fact date back
  to 19th century work of\nSchubert.
