Distillations: Science + Culture + History

Please note: In today’s episode we have included more mature content than a typical show. A Valentine for our listeners, this show is dedicated to the chemistry of love. In today’s show, we explain why passion has always been associated with fire and how the stars can influence your love life.

Today’s show takes a look at how scientists and educators are reinventing American science education. We chat with Tom Tritton, former president of Haverford College and CHF’s new president and CEO, about how to introduce liberal arts students to science—and just as importantly, vice versa.

We don’t normally think of computers, radios, and cell phones as products of chemistry, but none of these devices would be possible without specialized chemical manufacturing components and techniques. The integrated circuits at the heart of these tools depend on the unique electrical properties of certain inorganic elements such as silicon, germanium, and gallium.

Creating ink for both the printed and handwritten page, as well as preserving it, has a long history in which chemistry plays an integral part. Some historic inks have started to destroy the pages they’re printed on. Other books and manuscripts have been damaged as a result of older conservation practices that place more emphasis on looks than historic accuracy.
