Markus Reiner: The Father of Rheology
A Pioneer in the Study of Flow and Deformation
Markus Reiner, a renowned Israeli scientist, is best known for coining the term "rheology" and founding a society for its study. He, along with Eugene C. Bingham, laid the foundation for the field of rheology, which deals with the study of the flow and deformation of materials.
A Life of Discovery and Innovation
Born on January 5, 1886, in Czernowitz, Bukovina (then part of Austria-Hungary), Reiner obtained a degree in Civil Engineering from the Technische Hochschule in Vienna. After the First World War, he immigrated to Mandatory Palestine, where he worked as a civil engineer under the British mandate. He later became a professor at the Technion-Israel Institute of Technology in Haifa, where he continued his research in rheology.
Major Contributions to Rheology
Reiner's contributions to the field of rheology are immense. He, along with Bingham, coined the term "rheology" and founded the Society of Rheology. He is also known for:
- The Buckingham-Reiner Equation, a fundamental equation in rheology
- The Reiner-Riwlin Equation, which describes the behavior of non-Newtonian fluids
- Reiner-Rivlin fluids, a class of fluids that exhibit non-linear behavior
- The Deborah number, a dimensionless parameter that characterizes the behavior of complex fluids
- The Teapot effect, an explanation for why tea flows down the outside of a teapot spout instead of into the cup
Awards and Honors
Reiner's contributions to science were recognized through several awards and honors, including:
- The 1958 Israel Prize in exact science
- The 1966 Gold Medal of the British Society of Rheology
Legacy and Impact
Reiner's work has had a profound impact on various fields, including engineering, physics, and materials science. His research has led to a deeper understanding of the behavior of complex materials and has paved the way for numerous applications in industries such as:
- Materials processing and manufacturing
- Food processing and packaging
- Biological systems and biomaterials
In recognition of his contributions, the Technion-Israel Institute of Technology instituted the Markus Reiner Chair in Mechanics and Rheology. His legacy continues to inspire scientists and engineers, ensuring that his work will have a lasting impact on the scientific community.
Personal Life and Milestones
Reiner married Margalit Obernik and had two children, Ephraim and Hana. He later remarried Dr. Rivka Schoenfeld and had two daughters, Dorit and Shlomit. His granddaughter, Prof. Tal Ilan, continues to carry on his legacy in the field of rheology.
