This is largely a survey paper of the advancing boundary of first-passage percolation theory, containing also many new results and insights. Particular emphasis is placed upon the shape problem: What can be said about the asymptotic growth rate of the set of points attainable from the origin in less than time t, as \(t\to \infty ?\) There are careful discussions of some progress towards a small-deviation theorem for first- passage times, as well as a revised account of the large-deviation theory.

In two dimensions, first-passage percolation is basically equivalent to a problem in flows through randomly-capacitated networks. This suggests the problem of studying the network flow problem in its own right in higher dimensions. Certain results are reported in this direction. The paper terminates with a list of open problems.
