| A Picture of Georg Simon Ohm |
Early Life and Family Background:
Georg Simon Ohm came from a humble Protestant family.His father,Johann Wolfgang Ohm,worked as a locksmith,while his mother,Maria Elizabeth Beck,was the daughter of a tailor.Despite their lack of formal education,Ohm's parents were remarkable in their own right.Johann Wolfgang Ohm,in particular,was a self-taught individual who imparted a stellar education to his sons,Georg Simon and Martin,who later became a notable mathematician.Tragically,as was common in the era,several of the Ohm children did not survive infancy.Of the seven born to Johann and Maria Ohm,only Georg Simon,his brother Martin,and his sister Elizabeth Barbara lived to adulthood.
Early Education and Influence of Father:
During their formative years,Georg Simon and Martin received their education primarily from their father,who excelled in mathematics,physics,chemistry,and philosophy.Their education at home was a stark contrast to their uninspiring formal schooling,where rote memorization and text interpretation took precedence over genuine scientific exploration.This divergence was significant,with their father's teachings elevating them to a level of mathematical and scientific knowledge that drew comparisons to the famous Bernoulli family.
University and a Passion for Extracurricular Activities:
At the age of eleven,Georg Simon Ohm entered Erlangen Gymnasium.However,the formal education he received there did little to nurture his burgeoning scientific interests.Instead,he spent considerable time engaging in extracurricular activities,such as dancing,ice skating,and billiards.His father,dismayed by his son's apparent squandering of educational opportunities,insisted that Georg Simon leave the university after just three semesters.Subsequently,he was sent to Switzerland,where he assumed the role of a mathematics teacher in Gottstadt bei Nydau in September 1806.
Return to Academic Pursuits and Self-Study:
In early 1809,Karl Christian von Langsdorf,a professor at the University of Erlangen,left for the University of Heidelberg.Ohm desired to join him and resume his mathematical studies,but Langsdorf advised him to continue his studies independently.He recommended reading the works of Euler,Laplace,and Lacroix.Ohm,though somewhat reluctantly,followed this advice.In March 1809,he left his teaching position in Gottstadt bei Nydau to become a private tutor in Neuchâtel.During his two years as a tutor,Ohm combined his teaching duties with dedicated private study of mathematics.
Academic Achievements and Doctorate:
In April 1811,Ohm returned to the University of Erlangen.His private studies had prepared him well, and he earned a doctorate from Erlangen on October 25,1811.Subsequently,he joined the university staff as a mathematics lecturer.However,after three semesters,Ohm decided to relinquish his university post,given its limited prospects and the financial difficulties he faced.He accepted a position as a mathematics and physics teacher at a school in Bamberg,offered by the Bavarian government,in January 1813.
Struggles and Pursuit of Ambition:
Ohm's career at Bamberg was not the success he had envisioned.He realized that to achieve his ambition of securing a university post,he needed to demonstrate his worth beyond being a teacher in a subpar school.While disheartened by his teaching position,he dedicated himself to writing an elementary book on geometry.After enduring the school for three years,it was closed in February 1816,leading Ohm to be sent to another overcrowded school in Bamberg to assist with mathematics teaching.
On September 11,1817,Ohm received an offer for the position of a teacher of mathematics and physics at the Jesuit Gymnasium of Cologne,a more promising school with a well-equipped physics laboratory.During his time there,Ohm continued his private studies,delving into the works of prominent French mathematicians like Lagrange,Legendre,Laplace,Biot,and Poisson.He also began conducting his own experiments in the school's physics laboratory,influenced by Hans Christian Oersted's discovery of electromagnetism in 1820.However,Ohm's experiments initially served his personal educational benefit.
Transformational Work and Ohm's Law:
Despite facing a heavy teaching workload and a lack of appreciation,Ohm turned to scientific research to prove himself to the world and advance his career aspirations.He had become convinced of the truth of what we now call "Ohm's Law" during this time.This law states that the current flowing through a conductor is directly proportional to the potential difference applied across the conductor and Contrarily relative to it's obstruction.
In 1825,Ohm published his initial paper,which focused on the decrease in electromagnetic force produced by a wire as its length increased. Although this paper relied on experimental evidence,it did not contain the formulation of Ohm's Law itself.It wasn't until 1826 that Ohm published two crucial papers.These papers,inspired by Fourier's study of heat conduction,provided a mathematical description of electrical conduction in circuits,derived from his experimental observations.The second of these papers,in particular,laid the groundwork for Ohm's comprehensive theory,which he would present in his famous book published in 1827.
The Galvanic Circuit Investigated Mathematically:
Ohm's groundbreaking work culminated in his influential book titled "Die galvanische Kette,mathematisch bearbeitet" (The Galvanic Circuit Investigated Mathematically),published in 1827.The book commenced with a mathematical background necessary for understanding the rest of his work.However,it's important to note that,despite Ohm's efforts,he struggled to persuade older German physicists of the merits of the mathematical approach to physics,which was not the prevailing method of the time.
Ohm's theory introduced the concept of contiguous action,opposing the idea of action at a distance.He believed that electricity communicated between "contiguous particles."However,he faced challenges in conveying the unity of his theory and the connections between fundamental assumptions and major deductions.
Challenges and Recognition:

Despite the importance of his work,Ohm faced difficulties in gaining recognition.His mathematical approach and inward character didn't align with the non-mathematical methods prevalent in Germany at the time.Personal disputes,including conflicts with influential figures like Johannes Schultz and Georg Friedrich Pohl,further hindered his progress.
In 1833,Ohm accepted a position at Nuremberg,which granted him the title of professor but still fell short of his aspiration for a university post.However,his perseverance eventually paid off.In 1841,the Royal Society of London awarded him the prestigious Copley Medal,and in 1842,he became a foreign member of the Royal Society.He also gained recognition from acad emies in Berlin and Turin,which elected him as a corresponding member.In 1845,Ohm achieved full membership in the Bavarian Academy.
This belated recognition marked a turning point in Ohm's career,yet it raises questions about why a scientist whose contributions are now universally acknowledged faced such a struggle for acknowledgment in his time.Multiple factors likely contributed to this situation.Ohm's reserved personality,coupled with his insistence on a mathematical approach in a non-mathematical academic climate,presented challenges.Personal disputes with influential individuals further complicated matters.Nevertheless,Ohm's dedication and persistence eventually led to the recognition he deserved.
Contributions Beyond Ohm's Law:
While Georg Simon Ohm is primarily celebrated for Ohm's Law,his contributions to the field of physics extended beyond this fundamental principle.In 1843,he delved into physiological acoustics,exploring how humans perceive combination tones.However,his mathematical assumptions in this area faced criticism and led to a dispute with the physicist August Seebeck.Ohm acknowledged his error in the face of this critique,demonstrating his commitment to scientific rigor.
A Lifelong Ambition Achieved:
Ohm's determination and perseverance in the face of adversity eventually paid off.In 1852,just two years before his passing,he realized his lifelong ambition by being appointed to the chair of physics at the University of Munich.This achievement marked the culmination of his career,allowing him to impart his knowledge and passion for science to future generations.
Legacy and Recognition:
Today, Georg Simon Ohm is celebrated as one of the foremost pioneers in the field of electricity and magnetism.His eponymous law,Ohm's Law,remains a cornerstone of electrical engineering and physics,guiding engineers and scientists in understanding and manipulating electrical circuits.The ohm,the unit of electrical resistance,was named in his honor and serves as a constant reminder of his enduring contributions.
Ohm's commitment to a mathematical approach in the face of prevailing methods has left a lasting impact on the way physics is studied and understood.His work laid the groundwork for subsequent generations of scientists to build upon,and his legacy continues to inspire those who seek to unravel the mysteries of the natural world.
Georg Simon Ohm's life and work exemplify the power of determination and unwavering dedication to scientific exploration.From humble beginnings in a family without formal education,he transcended obstacles and challenged the norms of his time.Through relentless self-study,innovative experimentation,and the formulation of Ohm's Law,he reshaped our understanding of electricity and magnetism.
While Ohm faced resistance and skepticism during his lifetime,his contributions eventually earned him the recognition he rightfully deserved.His legacy endures not only through his eponymous law but also through the mathematical rigor he brought to the study of physics.Georg Simon Ohm's story serves as a testament to the enduring impact of those who dare to question,explore,and redefine the boundaries of human knowledge.
