On the second floor of section V is the "Fermi Room," where Enrico Fermi is said to have lived while working on the Manhattan Project in the 1940s. It is rumored that he chose that room because it had its own bathroom with tub; though the bathroom remains, the tub was replaced with a shower in 2008. Linked to the Fermi Room is the Fermi Blackboard, which is said to be the same blackboard Fermi used to do his calculations, although this may be an urban legend. This possibility does not, nevertheless, detract from many students' desire to possess it.
