Jeff D. Chalk III, ex-SMU professor who taught physics with flair, dies at 87

Lying on a bed of nails and ‘drinking’ liquid nitrogen were among the feats he pulled off to pique the interest of non-science majors

Jeff D. Chalk III was devoted to his students, whether lying on a bed of nails to drive home a point to non-physics majors or tirelessly working to help students seeking admission to medical or dental school.

Throughout his 30-year career at Southern Methodist University, the professor strove to learn the names of all his students, even those he taught in off-site classes via electronic hookup.

...Chalk was famous for the dramatic demonstrations he provided his general physics classes, showmanship that was designed to pique interest in science among non-majors, said his wife, Sarah Chalk of University Park.

One summer, the Chalks made a bed of nails.

“It was as big as a door. ... There were hundreds and hundreds of nails in that thing,” his wife said.

Chalk would lie on the bed of nails while a colleague used a sledgehammer to shatter a cinder block resting on his chest.
