The first kerosene lamp was constructed in 1853 by a Pole, Ignacy Lukasiewicz.
Lukasiewicz was a pharmacist who worked in the Lviv pharmacy "Under the Gold Star," owned by Piotr Mikolasch, a well-known Lviv businessman and pharmacist.
The Piarist Fathers' hospital in Lviv helped Łukasiewicz popularize his invention.
On July 31, 1853, in Lviv, doctor Zaorski, a surgeon, operated on his patient Władysław Holecki. The operation occurred at night in a room lit by one of Ignacy Łukasiewicz's first kerosene lamps.
The Three Gorges Dam causes a delay in the rotation of Earth.
The momentum is lost due to an enormous amount of water being forced through the dam. According to NASA estimates, the dam delays the rotation by 0,06 microseconds.
