Idaho 25 Goldback Design Meaning: Knowledge and the Dawn of Nuclear Power

Virtue: Scientia (Knowledge)
Enduring Principle: “There’s nothing worth knowing that isn’t difficult.” — Philo T. Farnsworth

The Idaho 25 Goldback represents the virtue Scientia, symbolizing the pursuit of knowledge, discovery, and scientific understanding. The design highlights one of the most important technological milestones of the twentieth century—the first successful generation of electricity from nuclear power, achieved in Idaho.

On December 20, 1951, scientists working at Experimental Breeder Reactor I (EBR-I) near Arco, Idaho, made history by producing the world’s first usable electricity generated from nuclear energy. Their demonstration famously lit four small light bulbs, proving that atomic energy could be harnessed for peaceful power generation.

Just a few years later, on July 17, 1955, the BORAX-III reactor expanded upon this breakthrough by providing electricity to the entire city of Arco, making it the first city in the world ever powered by nuclear energy.

At the center of the Idaho 25 Goldback design stands a female scientist, representing Idaho’s contributions to science and engineering, as well as the many women who have played essential roles in advanced research and technological progress.

Behind her appears a chalkboard filled with equations that helped shape the atomic age. One of these formulas is E = mc², introduced by Albert Einstein in 1905, which describes the relationship between mass and energy and forms the theoretical foundation of nuclear science. Another equation depicts the nuclear fission reaction of uranium-235, the process that released the energy used in the historic experiments conducted in Idaho.

These scientific breakthroughs established Idaho as a global center for nuclear research. The facility later became the National Reactor Testing Station, now known as Idaho National Laboratory (INL). Over the decades, the site has hosted more than fifty experimental nuclear reactors and continues to play a critical role in U.S. energy innovation, national security, and advanced technology research.

In recognition of its historic importance, EBR-I was designated a National Historic Landmark in 1966, acknowledging its worldwide impact on energy development.

Written on the note in the artwork is a quote from Idaho native Philo T. Farnsworth, the inventor of electronic television:

“There’s nothing worth knowing that isn’t difficult.”

Together, the imagery and message capture the essence of Scientia—the courage to pursue difficult questions and the determination to expand human knowledge. Through discovery and innovation, Idaho helped illuminate a new era of science and technology.
