    "abstract": "We consider the period of a simple pendulum in the gravitational field of the\nspherical Earth. Effectively, gravity is enhanced compared with the often used\nflat Earth approximation, such that the period of the pendulum is shortened. We\ndiscuss the flat Earth approximation, and show when the corrections due to the\nspherical Earth may be of interest.",
