Top 20 Incredible Facts about Georg Ohms


 

Georg Simon Ohm was a German physicist and mathematician who made an important discovery in the early 1800s that became the basis for our understanding of electrical circuits today. Even though Ohm had a very minimal education in math and science growing up, he was always fascinated by geometry, physics, and other technical subjects. He spent years teaching math and physics, but struggled to support himself financially as a teacher. In 1826, after years of experimenting, Ohm discovered that the electrical current passing through a material is directly proportional to the voltage.

So if you increase voltage, you proportionally increase current. This relationship became known as Ohm’s law, a fundamental law of physics and the basis for circuit theory. Even though the scientific community dismissed his findings at first, Ohm persisted and eventually his work became widely recognized. Today he is famous for this important law about electricity named after him. The unit of resistance, the ohm, also bears his name as a tribute to his influence.Lets take a look at some of the most incredible facts about him:

1. Ohm wasn’t formally educated in physics

Georg Ohm actually had very little formal education or training in physics and higher-level math. As a child, his family had little money for schooling beyond basic primary grades. However, Ohm found himself fascinated with how things worked from a young age. On his own initiative, Ohm taught himself principles of geometry, algebra, physics, and optics. Without university schooling or professor tutelage, Ohm absorbed technical knowledge simply by studying books during his spare time.

As a young man, Ohm worked full-time as a mathematics teacher. He continued his self-directed learning by reading physics texts after classes each day. The fact that Ohm established such a fundamental physical law as Ohm’s Law through self-study is remarkable. His achievement highlights the potential to grasp sophisticated technical subjects through self-motivation without formal advanced schooling.

2. Ohm also had a deep love for music and even wrote a book on musical theory

When Georg Simon Ohm first published his findings in 1826 about the direct relationship between voltage and electric current, he expected it to quickly revolutionize understanding of electrical circuits. However, the scientific establishment at the time largely dismissed his formula and provided little feedback. Ohm struggled for years to gain widespread acceptance. The renowned French physicist Jean-Baptiste Fourier even attacked Ohm’s theories publicly, hindering acceptance.

Leading scientific societies in Germany refused to publish Ohm’s research. In part, Ohm lacked the credentials and reputation to have his bold claim acknowledged right away. Additionally, the scientific culture of his day was skeptical of mathematical and theoretical breakthroughs not backed up by physical experimentation and demonstration. It was not until 1841 that Ohm’s fundamental relationship gained recognition, over 15 years after he formulated it.

5. Ohm’s mathematical approach to electricity was groundbreaking but also complex

Up until then, experiments with electricity often relied on qualitative descriptions and imprecise terminology about things like “intensity” that varied. Ohm formulated precise ratios and units for electrical concepts where none had formally existed before. However, his pioneering use of algebra and geometry to model electricity mathematically puzzled contemporaries in the physics community. Prominent scientists scoffed at the abstract nature of Ohm’s formula and diagrams, dismissing them as speculative drawings on paper rather than hard physics grounded in experimentation.

Accustomed to more descriptive formulations, they objected to his radical symbolic representation. The quantitative rigor of Ohm’s analysis was so avant garde and abstract that few could even grasp it fully, much less accept it. With persistence over years in demonstrating the predictive power of his equations, Ohm finally overcame early doubts about the suitability of applying mathematics in the blossoming field of electromagnetics during the 1800s.

6. Despite facing initial skepticism, received significant recognition for his groundbreaking contributions to physics
