 Lambert's ideas on entropy have been examined in a broad review of entropy by Jesper Haglund, Fredrik Jeppsson and Helge Strömdahl.Most notably, his work has influenced the way in which entropy (a concept defined mathematically in the technical literature) is presented in introductory textbooks and in popular science writing.Margulis and Eduard Punset have suggested that "The work of Frank Lambert, integrated into virtually all recent chemistry textbooks, makes clear that the second law is really a matter of energy dispersal."
