Sirius—the new Brazilian synchrotron light source—is one of the most powerful scientific tools on Earth, and Wolfram Language helped build it. Harry Westfhal Jr., director of the Brazilian Synchrotron Light Laboratory, explains how Wolfram was essential to designing this cutting-edge facility, which uses intense beams of light to study matter at a microscopic scale. He also reveals a world first: a high-security lab for studying deadly diseases, connected directly to Sirius. After 30 years with Wolfram Language, Harry shares why it remains his most trusted tool—for solving hard problems and rallying large teams around a bold vision.
