They are larger than penne and ziti, and sometimes slightly curved, though nowhere near as curved as elbow macaroni.

John Pasta "Limiting Procedures in Quantum Electrodynamics" in 1951 under the guidance of Hartland Snyder. He became a staff member of the Los Alamos Laboratory in August 1951. At Los Alamos National Laboratory Pasta would begin his work on his most famous projects. In 1952, working under Nicholas Metropolis on the MANIAC I, John Pasta aided in the construction of an early computer that specialized in calculations around weapons design. After working on the MANIAC I, Pasta continued on to work in the project he is most known for, the Fermi–Pasta–Ulam–Tsingou problem. After working alongside Enrico Fermi, Stanislaw Ulam, and Mary Tsingou,
