Why I Teach Science

J. Lichtman 2008, Harvard University

For me, science isn't just  a way of knowing  how things work. It's an ever-changing tool for understanding, navigating, and appreciating the entire world around us! And the worlds within us, as well.

Pictured above is a closeup of the brain's hippocampus. We can see each of the microscopic neurons within it, and all of their branching connections too. Together, these cells form a region that is critical for learning and memory--and it's just one of the many, many endlessly complex components of the brain! Somehow--and we still don't know how--these regions and circuits assemble to form the grand condition that is human consciousness.  We're still figuring it out. And in that way, we're kind of like brains learning about themselves, aren't we? 

This is just one scientific puzzle. There are infinitely more to solve. Some are thrilling, some boring, and others immensely difficult--but together, in practicing science, they bring us closer to understanding life and existence. In practicing science, we find meaning.

This is why I teach science: in this pursuit, we as learners and individuals are each made better. We are driven to think deeply and earnestly, and to seek both truth and meaning. We are challenged to be critical, and to collaborate -- and perhaps, even, to bring positive change to this little planet that we all call home. 

To pass on these skills would be my greatest honor.
