Why the pursuit of pure science is a necessity, not a luxury
In short: When Michael Faraday was asked about the practical value of electricity in 1850, he famously quipped, 'One day, Sir, you may tax it.' Today, his curiosity-driven research underpins our entire modern world, proving that fundamental exploration often yields the greatest returns.
In 1850, the UK Chancellor of the Exchequer, William Gladstone, visited the laboratory of Michael Faraday at the Royal Institution. At the time, Faraday’s investigations into electromagnetism appeared to be little more than scientific curiosities. However, his work on the fundamental laws of nature eventually provided the foundation for nearly all modern technology. Faraday discovered electromagnetic induction—the principle that a moving magnet generates an electric current—which remains the basis for electric motors and generators. He also identified diamagnetism, an effect capable of levitating objects within a magnetic field without power consumption.
The transition from experimental discovery to global utility required mathematical rigor. While Faraday was a brilliant experimentalist despite having little formal education or mathematical mastery, it was James Clerk Maxwell who later translated these findings into the Maxwell Equations. Published in the early 1860s, these equations continue to govern all known electric and magnetic phenomena. This mathematical framework accelerated a wave of innovation: Alexander Graham Bell transmitted the first telephone message in 1876, Edison patented the incandescent light bulb in 1880, and Heinrich Hertz demonstrated radio wave transmission in 1888.
Dr. Roberto Trotta argues that this pattern holds for astronomy, cosmology, and particle physics. He contends that while such fundamental research is often viewed as a luxury, the resulting cultural, technological, and scientific returns far outweigh the initial costs. Just as Faraday's 'unexplainable phenomena' eventually led to the ubiquitous technology we tax today, exploring the cosmos serves as a powerful, if serendipitous, driver of societal progress.
