[]
- The reciprocal of the fine-structure constant = 7.2973525643 x 10-3[1] is approximately equal to 137.035 999 084 (51).[2]
- There are 230 space groups, three-dimensional combination of Bravais lattices.[3]
- 299,792,458 is the speed of light in a vacuum, as measured in meters per second. It is usually denoted as \(c\).[4][5]
- Its prime factorization is 2 × 7 × 73 × 293,339.
- The radiation emitted by the hyperfine transition in the ground state of caesium-133 makes 9,192,631,770 oscillations per second.[6][7]
- Its prime factorization is 2 × 32 × 5 × 72 × 47 × 44,351.
- The mass–energy equivalence (E=mc2) implies, that a small mass corresponds to a large energy. For instance, a kilogram corresponds to the energy of 89,875,517,873,681,764 joules.
