    The same relations in different notation were used by Lorentz in 1913 and 1914, though he placed the energy on the left-hand side: ε = Mc 2 and ε 0 = mc 2, with ε being the total energy (rest energy plus kinetic energy) of a moving material point, ε 0 its rest energy, M the relativistic mass, and m the invariant mass.

    The compressibility for a typical liquid or solid is 106 bar −1 (1 bar = 0.1 MPa) and a typical thermal expansivity is 10 −5 K −1. This roughly translates into needing around ten thousand times atmospheric pressure to reduce the volume of a substance by one percent.

    The determinant of the order n Redheffer matrix is equal to M(n), so the Riemann hypothesis can also be stated as a condition on the growth of these determinants. Littlewood's result has been improved several times since then, by Edmund Landau, [6] Edward Charles Titchmarsh, [7] Helmut Maier and Hugh Montgomery, [8] and Kannan Soundararajan. [9]
