Luigi Galvani and the Discovery of Bioelectricity

Luigi Galvani and the Discovery of Bioelectricity

On September 9, 1737, Italian physician, physicist and philosopher Luigi Aloisio Galvani was born. He is best known for his discoveries in bioelectricity. In particular, he discovered that the muscles of dead frogs legs twitched when struck by a spark. As a legacy, Galvani’s name survives in the Galvanic cell, Galvani potential, galvanic corrosion, the galvanometer and galvanization. Moreover, his reports also heavily influenced famous author Mary Shelley writing her novel ‘Frankenstein‘.[4] “When…

Jöns Jacob Berzelius – One of the Founders of Modern Chemistry

On August 20, 1779, Swedish chemist Jöns Jacob Berzelius was born. Berzelius is considered, along with Robert Boyle, John Dalton, and Antoine Lavoisier, to be one of the founders of modern chemistry. In Sweden, Berzelius Day is celebrated on 20 August in honor of him. “Every chemical combination is wholly and solely dependent on two opposing forces, positive and negative electricity, and every chemical compound must be composed of two parts combined by…

Humphry Davy and the Wonders of Electrolysis

Humphry Davy and the Wonders of Electrolysis

On November 19, 1807, British chemist and inventor Humphry Davy reported to the Royal Society about the isolation of potassium and sodium from different salts by electrolysis. Davy was one of the pioneers in the field of electrolysis using the newly invented voltaic pile to split up common compounds and thus prepare many new elements.[6] “Nothing is so fatal to the progress of the human mind as to suppose that our views…

Georg Christoph Lichtenberg – Master of Aphorism

On July 1, 1742, German scientist, satirist and Anglophile Georg Christoph Lichtenberg was born. He is remembered best for his posthumously published notebooks, which he himself called Sudelbücher, a description modeled on the English bookkeeping term “scrapbooks”, and his aphorisms. A book is a mirror: if an ape looks into it an apostle is hardly likely to look out. We have no words for speaking of wisdom to the stupid. He who understands…

On the Road with Alexander von Humboldt

On August 3, 1804 geographer, naturalist, and explorer Alexander von Humboldt returned home from his great South America scientific discovery journey. “I am more and more convinced that our happiness or unhappiness depends more on the way we meet the events of life than on the nature of those events themselves”. – Alexander von Humboldt Aimé Bonpland and Daniel Kehlmann Actually, Humboldt did not make this journey all alone. He had a…

Alessandro Volta and the Electricity

On March 20, 1800, Italian physicist Alessandro Volta informed the British Royal Society in London about his newly invented electric power source, the Voltaic pile, the first energy source technology capable of producing a steady, continuous flow of electricity. “The language of experiment is more authoritative than any reasoning: facts can destroy our ratiocination—not vice versa. “ — Count Alessandro Giuseppe Antonio Anastasio Volta, Quoted in [12] First Experiments with Eletricity Alessandro…

Charles Wheatstone – From the Concertina to the Telegraph

On February 6, 1802, Charles Wheatstone, English scientist and inventor of many scientific breakthroughs of the Victorian era was born. He is well known for his research in acoustics, electricity, and telegraphy. Family Background and Early Youth Well, if you don’t happen to be an engineer or a physicist, then you have probably never heard of Charles Wheatstone. But we will show you that he was really some remarkable fellow. Charles Wheatstone was born…

Nicholas Callan and the Induction Coil

Nicholas Callan and the Induction Coil

On December 22, 1799, Irish priest and physicist Nicholas Callan was born. Callan invented the induction coil (1836) before that of better-known Heinrich Ruhmkorff. Callan‘s coil was built using a horseshoe shaped iron bar wound with a secondary coil of thin insulated wire under a separate winding of thick insulated wire as the “primary” coil. Each time a battery‘s current through the “primary” coil was interrupted, a high voltage current was produced in…
