The Dumbest Question You Can Ask a Scientist

No one who knows the history of science would ask this question.

The dumbest question you can ask a scientist — or any other creator, inventor, or discoverer — about his or her work is,

“What’s the economic value?”

One reason: In 1888, after eight years of experiments, Heinrich Hertz created electromagnetic waves in air. He died six years later, believing his work was theoretical and without practical value. (In an often repeated, probably apocryphal story, Hertz tells students the waves have “no use whatsoever.”) Then, after his death, inventors found Hertz’s waves could be used to communicate, renamed them “radio waves,” and started a revolution of immeasurable consequence. First came wireless telegraph, then voice broadcasting, two-way radio, radio telescopes, radar, television, microwave ovens, radio satellites, cellphones, radio-frequency identification, GPS, UAVs, Bluetooth, Wi-Fi and, now, the Internet of Things — Hertz’s children all.

Another reason: In 1924, Gordon Dobson, working in his backyard in England, invented a device for measuring atmospheric ozone. In 1976, after deploying 100 of them globally, he died. His work helped save the world. Scientists discovered that CFCs, chemicals used in refrigerators and aerosols, could destroy ozone, exposing us to deadly…
