In science:

For c < 1 the result follows from the fact that the random graph is a collection of trees and unicyclic graphs of logarithmic order, which gives the upper bound, and that there is one of these components with large diameter with respect to its order, providing the lower bound.
On the tree-depth of Random Graphs
We will first prove the upper bound. A unicyclic graph (unicycle) is a connected graph that has the same number of vertices than edges, that is, the graph contains exactly one cycle.
On the tree-depth of Random Graphs
Lemma 4.1 If each connected component of G is either a tree or a unicycle, then td(G) ≤ log nc + 2, where nc is the cardinality of the largest connected component of G.
On the tree-depth of Random Graphs
One of the central results of Erd ˝os and R ´enyi [?] states that, if 0 < c < 1, then G is composed by trees and unicycles.
On the tree-depth of Random Graphs
For a unicyclic component, i.e. a tree with an extra edge, we can consider all the k2 colourings of the endpoints of the extra edges and for each of these colourings recurse on the remaining tree.
