Photo of “El Cid Campeador, an outdoor equestrian statue depicting the 11-century Spanish knight and warlord El Cid by artist Anna Hyatt Huntington, architect William Templeton Johnson, and the foundry General Bronze Company, installed at Balboa Park’s Plaza de Panama in San Diego, California.

Vance and Donald Trump haven’t invented any “Vance” or “Trump” rules in spectroscopy, but there is an El Sayed rule. One of the incidents that impelled El Sayed to go into politics was the lead poisoning of Flint, Michigan, by a penny-pinching and ignorant Republican governor, Rick Snyder. As a physician and a man of science, Dr. El Sayed cares about ordinary Americans.
