they heralded a new era in the field of chemical kinetics; allowing the prediction of the dynamical course of a chemical reaction.

. However, Lee has been criticized by some for his involvement in educational reforms that they claim to have put unnecessary burden and administrative complications on the students and reduced competitiveness of higher education. Some critics also claim that Lee should stick to the sciences and stop using his Nobel pedigree to influence educational and political policies, areas with which they asserted he is not familiar.

In 2010, Lee said that global warming would be much more serious than scientists previously thought, and that Taiwanese people needed to cut their per-capita carbon emissions from the current 12 tons per year to just three. This would take more than a few slogans, turning off the lights for one hour, or cutting meat consumption, noting: "We will have to learn to live the simple lives of our ancestors." Without such efforts, he said, Taiwanese will be unable to survive long into the future.

Personal life

Lee married Bernice Wu Chin-li (吳錦麗 Wú Jǐnlì), whom he has known since elementary school. They have three children: Ted (journalist), Sidney (doctor), and Charlotte (sociologist).
