Artistic Connections

Royal Festival Hall Auditorium,1951.
Author: Robin and Lucienne Day Foundation

Marion Ross always took a keen interest in music, especially organ music, inspired by her father. He had designed the organ for the Holy Rude Church in Stirling, and composed organ music. Marion founded a trust so that a prize for composition could be awarded to encourage the work of Scottish church musicians. The prize continued to be awarded after her death.

As Assistant Lecturer at Edinburgh University, Marion Ross set up a course in acoustics for music students. She took a keen interest in the construction of the Royal Festival Hall in London, one of the first concert halls to be designed for its acoustical qualities, not entirely successfully!

Marion Ross was the focus for this group during their Minerva Scientifica workshops. Her story – told to them by Catherine Booth from the National Library of Scotland – inspired them to think of all the amazing things in the world that they would like to investigate – just as she did. They start by sharing her musical and scientific background and then you’ll hear what they want to know!

Education

Marion Ross was educated at Edinburgh Ladies College then Edinburgh University. She trained as a teacher of mathematics in Cambridge. She gained her PhD back at Edinburgh University.

Occupations

Teacher
Marion Ross taught mathematics for several years, both in Woking, Surrey, and in Falkirk, Scotland

Crystallographer
For one year in the 1930s, she worked as a crystallographer in Manchester University collaborating with Dr C A Beevers, under the guidance of Sir W. Lawrence Bragg. Sir Lawrence had been awarded a Nobel prize for his work in crystallography in 1915.

Wartime Researcher
During WW2, Marion Ross spent 4 years working with the Admiralty at Rosyth, Fife, and became Head of the Research Group.  Their investigations involved underwater acoustics and hydrodynamicsBottom bounce.JPG

Lecturer
After the war, Dr Marion Ross became a lecturer in the Physics Department at Edinburgh University, where she remained for the rest of her career, specializing in areas such as nuclear and X-ray physics and fluid dynamics.

Scientific Achievement

  • Beta-alumina diagram

      • During her year as a crystallographer, Ross and Beevers investigated the crystal structure of a molecule, ‘beta-alumina’ and published their results in a German journal in 1937. They found a problem anomaly in the structure where sodium ions were present, and these locations became known as ‘Beevers-Ross’, or ‘anti-Beevers-Ross’ sites. The two scientists could not see any practical application for these, and simply noted them as interesting. Years later, it was discovered that the mobile sodium ions form efficient fast ion conductors, important in battery technology.

  • At Edinburgh University, Marion Ross set up a laboratory to conduct experiments in nuclear physics. These included the detection of charged particles on photographic plates. X-ray imaging is a familiar medical application of this branch of science, though digital technologies have now taken over.
  • Fluid dynamics – the flows of liquids and gases – was a continuing scientific interest for Marion Ross, and she set up a Fluid Dynamics unit within the University. Experiments to investigate smooth and turbulent flows were undertaken using a low-speed wind tunnel, but also required mathematical calculations using the properties of the gas or liquid under consideration, such as its pressure and temperature.

Did You Know?

Marion Ross was the eldest daughter in a family of 5 girls. Her father, William Baird Ross, was a well-known organist and composer of organ music.
She once told a young student that she enjoyed playing table tennis, and if she didn’t have a bat to hand, she would hit the ping-pong ball with a text book!  This either shows her sense of fun or her inventiveness – perhaps both!

An Inspiring Woman

Science requires careful observation and recording of results. Sometimes the implications of a discovery are not immediately obvious at the time, but noted for future study. Marion Ross and her colleague were in just that position when they spotted the properties of the beta-alumina crystal.  Fortunately they wrote and published a description of it, and scientists working in a different field much later, followed up this work, and realized its importance.
Marion Ross encouraged and supervised many young and advanced students in her time. These days she inspires many working with us on Minerva Scientifica, particularly the children of Canal View Primary School who wrote a song about her (see Music above).
