Mark A. Yeager

Professor of Chemistry and Physical Science

...one or two atoms can convert a fuel to a poison, change a color,
render an inedible substance edible, or replace a pungent odor
with a fragrant one. That changing a single atom can have such
consequences is the wonder of the chemical world.

                   -- P. W. Atkins, "Molecules",W.H. Freeman and Company, New York, 1987.

The most exciting phrase to hear in science, the one that heralds
the most discoveries, is not "Eureka!" (I found it!) but "That's funny..."

                   -- Isaac Asimov (Biochemist and author).
A tidy laboratory means a lazy chemist.
                -- Jöns Jacob Berzelius (Swedish chemist,1779-1848)

Educational Philosophy

The two most important characteristics a scientist must have are a true sense of Wonder, and profound, but not cynical, Skepticism. Science is the method we humans use to try to figure out how the universe works, and without both wonder and skepticism, Science fails. Education in chemistry (and in the other sciences) has often simply presented the knowledge that has been built through science, leaving out all of the wonder and most of the skepticism that goes into the process of Science.

Science education should employ and encourage both Wonder and Skepticism, just as it should demonstrate and elucidate concepts and skills.  The process of science should be used to teach science, as well as being a subject of science education.  That is why I use an inquiry based approach wherever I can. Chemistry, as a science, is based on experiment. It should be taught in a hands-on manner, where students learn not just by reading and listening, not just by carrying out "cookbook" laboratory exercises, but by designing and performing their own experiments.

Science is a uniquely human endeavor, and I feel that it is very important for students to feel a connection to the humanness of science, to its history and its process. Science is not just a huge collection of facts, it is an ever-evolving picture of the universe, as seen through human eyes. It is also the many men and women who have contributed, and who continue contributing, to this picture.

Richard Feynman, one of the greatest physicists of our time, wrote:

"The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific 'truth.' But what is the source of knowledge? Where do these laws come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations--to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess." 

I am very enthusastic about science in general, and about chemistry in particular. If I can use my own enthusiasm for chemistry to ignite my students' sense of wonder, and that this leads them to a greater interest in, and a better working knowledge of the chemistry and science they are learning, then I have been successful.
