On August 14, 1777, the Danish physicist and chemist Hans Christian Orsted was born in Rudkobing.

On this day (August 14), 1777, the Danish physicist and chemist Hans Christian Orsted was born in the town of Rudkobing, (Denmark).
As a child, he developed an interest in science while working for his father, who owned the local pharmacy . He and his brother Anders received most of their early education through self-study at home, going to Copenhagen in 1793 to take entrance exams to the University of Copenhagen, where both brothers excelled academically.
He received his doctorate in 1799 for a dissertation based on the works of Kant entitled The Architectonics of Natural Metaphysics .
In 1800, Alessandro Volta reported his invention of the voltaic cell , which inspired Ørsted to investigate the nature of electricity and to conduct his first electrical experiments. In 1801, Ørsted received a traveling scholarship and a public grant that allowed him to spend three years traveling in Europe. He toured scientific sites across the continent, including Berlin and Paris.
In Germany, Ørsted met Johann Wilhelm Ritter , a physicist who believed there was a connection between electricity and magnetism . This idea made sense to Ørsted since he subscribed to Kantian thought with regarding the unity of nature.
In 1820, Ørsted published his discovery that the needle of a compass was deflected from the magnetic north by a nearby electric current, confirming a direct relationship between electricity and magnetism.
For his discovery, the Royal Society of London awarded Ørsted the Copley Medal in 1820 and the French Academy awarded him 3,000 franks. Ørsted was elected a foreign member of the Royal Swedish Academy of Sciences in 1822, member of the American Philosophical Society in 1829, and Foreign Honorary Member of the American Academy of Arts and Sciences in 1849.
Ørsted's findings sparked much research on electrodynamics throughout the scientific community, influencing the developments of the French physicist André-Marie Ampère of a unique mathematical formula to represent the magnetic forces between current-carrying conductors. Ørsted's work also represented a major step towards a unified concept of energy.
As a curiosity, comment that Ørsted was the first modern thinker to explicitly describe and name the mental experiment. He used the Latin-German term Gedankenexperiment around 1812 and the German term Gedankenversuch in 1820.

- What are you doing Hans?
- I'm studying the currents..
- Well, I'll open the windows for you
- why?
- so you can study better
- but it's very cold and windy
- best
- better?
- there will be more current
- How?
- so that you could better study the currents
- the currents of what?
- drafts
- no, I study currents of electricity
- that doesn't seem so common to me
- because you don't know her
- can you speak?
- well, I'm going to see the birds
