Edward Bullard
Sir Edward Crisp Bullard FRS (21 September 1907 – 3 April 1980) was a British geophysicist who is considered, along with Maurice Ewing, to have founded the discipline of marine geophysics. He developed the theory of the geodynamo, pioneered the use of seismology to study the sea floor, measured geothermal heat flow through the ocean crust, and found new evidence for the theory of continental drift. Early life Bullard was born into a wealthy brewing family in Norwich, England. His maternal grandfather was Sir Frank Crisp and his paternal grandfather was Sir Harry Bullard, who had been an MP for Norwich. He was educated at Norwich School and later studied Natural Sciences at Clare College, Cambridge. He studied under Ernest Rutherford at the Cavendish Laboratory of University of Cambridge and in the 1930s he received his PhD degree as a nuclear physicist. Bullard found poor career prospects for nuclear physicists during the Great Slump, so in 1931 he switched fields to ...

Killam Professor
The Killam Trusts were established in 1965 after the death of Dorothy J. Killam, the widow of Izaak Walton Killam, a Canadian financier, for a time the wealthiest man in Canada. He died intestate in 1955, but before his death he and his wife discussed in extensive detail the scholarship plan on which the Killam Trusts were founded. Approximately one half of his estate went to the government as inheritance tax. It was used to found the Canada Council, along with similar funds from the estate of Sir James Dunn, also from Nova Scotia. The rest of Killam's estate was inherited by his widow. In the ten years between his death and hers, she doubled the Killam fortune. Upon her death at Villa Leopolda, her lawyer put into motion the plans the Killams had discussed during their lifetimes. Having no children of their own, the Killams decided to leave their fortune to further post-secondary education in Canada at the graduate level. The Killam benefactions went to five Canadian univers ...

Planetary Differentiation
In planetary science, planetary differentiation is the process by which the chemical elements of a planetary body accumulate in different areas of that body, due to their physical or chemical behavior (e.g. density and chemical affinities). The process of planetary differentiation is mediated by partial melting with heat from radioactive isotope decay and planetary accretion. Planetary differentiation has occurred on planets, dwarf planets, the asteroid 4 Vesta, and natural satellites (such as the Moon). Physical differentiation Gravitational separation High- density materials tend to sink through lighter materials. This tendency is affected by the relative structural strengths, but such strength is reduced at temperatures where both materials are plastic or molten. Iron, the most common element that is likely to form a very dense molten metal phase, tends to congregate towards planetary interiors. With it, many siderophile elements (i.e. materials that readily alloy with iron ...
