Google celebrates scientist Alessandro Volta's birthday with a doodle
Google's home page marks Italian scientist Alessandro Volta's birthday with a doodle to honour the inventor of electric cell in 1799 named after him and known as Volta cell later converted into an early battery in 1800.

The doodle is interactive and a click on it shows the Voltaic battery charging and Google logo lighting up simultaneously. With another click it takes visitor to a Google search of Alessandro Volta's top links. These links provide access to articles about Volta's life and works.

History of science informs that the battery made by Volta is credited as the first usable electrochemical cell. A simple Volta cell consists of two electrodes, zinc and copper dipped in electrolyte which is either sulfuric acid mixed with water or a form of saltwater brine.

As a professor of physics in 1774 at Como's Royal School, he also did research on electrophorus device that produced static electricity. Recognizing his work, Volta was made a Count in 1810 by Napoleon Bonaparte.

He retired in 1819 to settle down at his estate in Camnago but could not live long. He died in 1827. A museum has been built in his memory to honour his work in electrical science.
