Dr. Kari Dalnoki-Veress demonstrates the astounding strength of two phone books connected only by interweaving the pages together. Dr. Dalnoki-Veress has recently published an analysis of the long-known but unexplained phenomenon and a model of the system with French colleagues in Physical Review Letters. This model system provides a framework for the accurate measurement of friction forces and coefficients at low loads and is relevant for complex assemblies spanning from the macro- down to the nanoscale.
The McMaster daily news covers the strength of the assembly and provides a real-world demonstration in a video pitting students in a tug-of-war against the friction between sheets of paper. You can read more and watch the videohere.
On Jan. 21, Dr. Christine Wilson will give a talk entitled "New Eyes on the Cold Universe" focusing on the latest findings from the Atacama Large Millimetre Array (ALMA) observatory. The array of 66 radio telescopes is located on a high plateau in the Chilean desert and has recently found evidence of a young star, HL Tauri, in the Taurus constellation which appears to be in the midst of forming a planetary system. Christine was involved in an international team involved in the design and construction of the array between 1999 and 2014 and will be discussing the latest exciting discovery in the talk as part of the "Research in the City" lecture series at the McMaster Innovation Park.
