In 1800, Alessandro Volta invented the voltaic pile, allowing for a continuous current of electricity for experimentation. This became a source of a low-voltage current.
The most popular song of the 1800s was Good Morning to All (Happy Birthday To You).
Dr. Salva presented at the Academy of Natural Sciences and Arts of Barcelona his first report devoted to “The Electricity applied to telegraphy.” Salva demonstrated the basis of electric telegraphy, anticipating the wireless telegraph and undersea cables.
The punch card is a piece of stiff paper that can be used to contain digital data represented by the presence or absence of holes in predefined positions. Digital data can be used for data processing applications or, in earlier examples, used to directly control automated machinery.
English inventor Francis Ronalds built the first working electric telegraph.
Charles Xavier, Thomas, de Colmar invented the ‘Arithmometer,’ which, after thirty more years of development, became, in 1851, the first mass-produced mechanical calculator. An operator could perform long multiplications and divisions quickly and effectively by using a movable accumulator for the result. This machine was based on the earlier works of Pascal and Leibniz.
Hans Christian Ørsted discovers the relationship between electricity and magnetism in a very simple experiment. He demonstrates that a wire carrying a current was able to deflect a magnetized compass needle.
Charles Xavier Thomas de Colmar creates the “Arithometer,” the first reliable, useful, and commercially successful calculating machine. The calculator could not only add but also subtract, multiply, and divide.
German scientist Thomas Johann Seebeck discovered thermoelectricity.
Charles Babbage designed his first mechanical computer, the first prototype of the decimal difference engine for tabulating polynomials.
Baron Jons Jackob Berzelius discovered silicon (Si), which today is the basic component of an integrated circuit (IC).
English physicist William Sturgeon developed the first electromagnet.
Nicéphore Niépce makes what is now the earliest surviving photograph from nature, a landscape. It requires exposure in the camera that lasts at least eight hours and probably several days.
German physicist Georg Ohm introduced the concept of electrical resistance.
Semen Korsakov proposed the usage of punched cards for information storage and search.
On October 21, 1832, Pavel Schilling became the first to transmit signals between two telegraphs in different rooms of his apartment.
Joseph Henry invented the electromechanical relay.
Henry Fox Talbot produces durable silver chloride camera negatives on paper and conceives the two-step negative-positive procedure used in most non-electronic photography up to the present.
