The life and times of John Beard, DSc (1858-1924).

The British developmental biologist John Beard, DSc (1858-1924) is little remembered today. Yet, he made outstanding contributions to the life sciences. Beard deserves to be included among the leading biologists of the late 19th and early 20th century. He has been hailed as a forerunner of the present-day theory of the cancer stem cell (CSC).

On quantization with the Weaire-Phelan partition

Until recently, the solution to the Kelvin problem of nding a partition of R 3 into equal-volume cells with the least surface area was believed to be tessellation by the truncated octahe-dron. In 1994, D. Weaire and R. Phelan described a partition that outperformed the truncated octahedron partition in this respect. In this paper, we show that the eeective normalized moment of inertia (NMI) of ...
