The fascinating story of JJ Thomson's discovery of the electron dates back to the late 19th century when scientists were still trying to understand the mysteries of the atom. In 1879, a charismatic English chemist named William Crookes proposed that the cathode ray, a beam of charged particles in a vacuum tube, was composed of charged particles. This idea sparked a chain reaction of research, leading Thomson to embark on his journey to discover the electron.

Thomson's discovery began with an attempt to explain the discrepancy between the behavior of cathode rays under magnetic and electric forces. In 1897, he successfully isolated the first subatomic particle, the electron, through a series of experiments involving the cathode ray tube. The process was not without its challenges, as Thomson faced numerous trials and errors before finally pinning down his groundbreaking discovery.

Thomson's research was marked by an unerring ability to pinpoint interesting phenomena for himself and others. He had incredible resources, stability, and ability to research whatever he wished, which ultimately led him to discover the electron. His discovery revolutionized our understanding of the atom and paved the way for future scientific breakthroughs.

In his early years, Thomson faced several challenges, including the death of his father when he was just 14 years old. This left his family without enough money to fund his apprenticeship to a locomotive engineer. Instead, he applied to Owens College at the tender age of 14 and was accepted. Despite the initial shock to the authorities, who feared that students would soon be coming in perambulators, Thomson went on to excel academically.

Thomson's discovery of the electron has had a lasting impact on our understanding of the atom. Scientists have since established that the atom is not indivisible as Dalton believed, and due to the work of Thomson, Millikan, and others, the charge and mass of negative subatomic particles, known as electrons, are now well understood.

In conclusion, JJ Thomson's discovery of the electron was a groundbreaking achievement that marked a significant turning point in the history of science. His innovative research and perseverance paved the way for future scientific breakthroughs, cementing his place as one of the most important scientists of all time.
