The Nature of Motion – A Lazy (or Very Efficient) Universe

Professor Eisenkraft delves into the elegance of Least Action, proposing insights for enhanced learning and teaching methods.

We understand movement through dance, sports, and transportation. We use models (equations, graphs, pictures) to communicate our knowledge. We explain motion in terms of forces, fields, and energy. How do we choose which models and explanations are best? 

A physicist’s best model is no longer Newton’s laws but rather Least Action and, yet it is not taught in our schools. Professor Eisenkraft will explore the principle of Least Action and sense its beauty. Through this exploration, we will gain insights into improved learning and teaching.

About the Speaker

Dr. Eisenkraft is past president of the National Science Teaching Association (NSTA) and past chair of the Science Academic Advisory Committee of the College Board. He leads Active Physics and Active Chemistry introducing high-quality project-based science to students. 

He also chairs (and co-created) the Toshiba/​NSTA Explora Vision Awards, involving 15,000 students annually for over 30 years. He leads the Wipro Science Education Fellowship programme which is bringing district transformation through teacher leadership across the US

His current research projects include investigating the efficacy of a second-generation model of distance learning for professional development and a study of professional development choices that teachers make when facing a large-scale curriculum change.

Eisenkraft has received numerous awards recognising his teaching and related work including the National Science Board’s Public Service Award, AAPT’s Millikan Medal, and NSTA’s Carleton Award. He is a fellow of the AAAS and holds a patent for a laser vision testing system.
