Two years, in a person’s life, may be very short. But two years can also be enough to make a qualitative change in a person’s life. During Arthur Hastings’ tenure as Göttingen University Supervisor and National Special Representative from 1833-1834, what contributions did he make to the progress of human civilization as a whole?
George Ohm, who was buried in the academic world, was rediscovered by him. This future Copley dal winner, a great scientist famous throughout Europe, shone brilliantly at the University of Göttingen. With Arthur Hastings’ help, Gauss and Weber built the world’s first geomagnetic monitoring station and, together with Alexander von Humboldt and Charles Wheatstone, established the Göttingen Electromagnetic Society.
The future Iron Chancellor of the German Empire, Bismarck, first showed his edge in Göttingen. Although at this ti he was still just a hot-tempered youth, Arthur quickly taught him the techniques of dealing with ’creepy-crawlies’. And when Bismarck gained great power in the Gestapo, a child from an ordinary farming family traveled over a hundred miles to the small town of Göttingen in Hanover.
Although this child would beco a pivotal figure in the German industrial world in many years to co, possessing wealth that people around the world envied, at that ti, he was still worrying about his university tuition. He wished to continue pursuing the noble profession of applied science, but if he couldn’t solve his financial problems, he would have to face the harsh reality of giving up his dream and dropping out.
—— Eld Carter "Arthur Hastings and the Free Constitutional Reform of the Kingdom of Hanover"
The laboratory at the University of Göttingen, the air was filled with a slight tallic sll.
The recently renovated lab was very spacious and bright, but as the latest purchased instrunts had not yet arrived, there were only a few simple wooden tables piled with books, manuscripts, and equipnt, with various circuit diagrams and hand-drawn sketches by scientists hanging on the walls.
Gauss, Weber, Ohm, and Arthur were tightly gathered around an experint table full of various copper coils, batteries, and magnets.
However, while there were four people standing here, only Ohm was actually doing the work.
It wasn’t that Gauss, Weber, and Arthur didn’t want to help, but they intended to see with their own eyes how Ohm himself would replicate the experint.
The experintal apparatus used by Ohm was not much, only a few thermoelectric batteries, a long copper wire, a sliding resistor, and two crude amters he made himself.
Under everyone’s watchful eyes, beads of sweat dotted Ohm’s forehead as he carefully connected the circuit, taking every step cautiously to ensure good contact.
He knew that these experints were not just to verify his ideas but also to prove to the academic world that the linear relationship between current and voltage is universal, unaffected by material or direction of current. Moreover, this might be the last opportunity of his life.
Mathematician giant John Karl Gauss, electromagnetic genius William Weber, and the second British electromagnetic authority under Faraday, Arthur Hastings, were all watching!
Then, he connected the amter to the copper wire, and as the current was switched on, the needle of the amter gently flicked, indicating the current passing through the wire. Ohm knew that every piece of data he was about to asure was crucial.
He adjusted the battery’s voltage, and after each change, he carefully recorded the values of voltage and current. His hand held the voltter steadily, observing and pondering. After each record, Ohm would pause for a mont, carefully checking the data to ensure there were no errors.
As data was recorded line by line on paper, Gauss, extrely sensitive to numbers, had already noticed subtle patterns.
But the cautious Gauss didn’t express his insights imdiately; instead, he politely asked Ohm,"Excuse , Mr. Ohm, could I borrow that sliding resistor you’re holding?"
Hearing Gauss speak, Ohm imdiately removed the sliding resistor and offered it with both hands, "Of course, you can use it as long as you want."
"Thank you." Gauss took the sliding resistor, turned silently, and began rebuilding the circuit using the laboratory’s equipnt.
Even though Ohm had verified the experint in front of him, Gauss still harbored doubts about the final result, suspecting that the linearity between current and voltage might be due to the insufficient precision of Ohm’s self-made amters.
Gauss had already begun experinting on the other side, but Weber and Arthur were still gathered around the experint table, examining the manuscript paper with recorded experintal data over and over.
Weber raised an eyebrow and nudged Arthur with his elbow, lowering his voice, "Your Excellency, the Supervisor, have you figured it out?"
Arthur didn’t speak, he rely picked up a pen from the experint table and wrote a formula in the blank space on the paper—Voltage = Current x Resistance.
Seeing this formula, Weber turned to look at the experintal data, and couldn’t help but chuckle, "Previously, Mr. Navier and Mr. Coriolis wrote and said you are a genius in mathematics. At the ti, I didn’t believe it, but now it seems they weren’t wrong at all."
And when Ohm saw the formula Arthur had written, he clenched his fists excitedly.
