The prestigious and excellent University of Edinburgh has invited Chaired Professor Javier Martin-Torres to give a keynote talk next May 29th at the Erskine Williamson Day organized by the Centre for Science and Extreme Conditions and the U.K. Centre for Astrobiology. This year the activity is focus on the topic “Astrochemistry and Astrobiology at Extremes”.

The content of Chaired Professor keynote talk will be “Salts under Martian pressure and temperature conditions and the ESA HABIT instrument on ExoMars”.

Erskine Williamson (10 April 1886 in Edinburgh – 25 December 1923) was a charismatic Scottish geophysicist. Following degrees from The University of Edinburgh and a period on a Research Scholarship from the Carnegie Trust of Scotland, and in the brief nine years till his early death in 1923, he earned an international reputation for outstanding and elegant experimental studies and theoretical calculations in high-pressure physics, physical chemistry, petrology, glass science and geodynamics. He published with L. H. Adams what is regarded as one of the most important contributions to geophysics in the first half of the 20th century: the famous Adams-Williamson equation. The euqation is used to determine density as a function of radius, more commonly used to determine the relation between the velocities of seismic waves and the density of the Earth's interior, and then is used for determining the interior structure of the Earth from seismic velocities.

This equation remains widely known and used to this day:

The “Erskine Williamson Day” is an initiative to honor the memory of this great scientist with nowadays key ground-breaking contributions in in materials research and modern studies of planetary interiors.
