**Sound recording** with phonatograph was invented in 1857 in Paris, however it could not be played back at the time -- the first record of human voice made with this technology can nowadays be reconstructed and played back. It wouldn't be until 1878 when people could both record and play back sounds with [Edison](edison.md)'s improvement of phonatograph. A year later, in 1879, Edison also patented the **light bulb**, even though he didn't invent it -- there were at least 20 people who created a light bulb before him. [Pi](pi.md) at this time is evaluated to roughly 500 digit accuracy (using Machin's formula).
Around 1888 so called **war of the currents** was taking place; it was a heated battle between companies and inventors for whether the [alternating](ac.md) or [direct](dc.md) current would become the standard for distribution of electric energy. The main actors were [Thomas Edison](edison.md), a famous iventor and a huge capitalist dick rooting for DC, and George Westinghouse, the promoter of AC. Edison and his friends used false claims and even killing of animals to show that AC was wrong and dangerous, however AC was objectively better, e.g. by its efficiency thanks to using high voltage, and so it ended up winning the war. AC was also supported by the famous genius inventor [Nikola Tesla](tesla.md) who during these times contributed hugely to electric engineering, he e.g. invented an AC motor and Tesla coil and created a system for wireless transmission of electric power.

Also in 1888 probably the **first [video](video.md)** that survived until today was recorded by Lou Le Prince in Northern England, with a single lens camera. It is a nearly 2 second silent black and white shot of people walking in a garden.
