Heinrich Friedrich Emil Lenz was a physicist of Baltic German ethnicity. He is most noted for formulating Lenz's law in electrodynamics in 1833. The symbol L, conventionally representing inductance, is chosen in his honor.

Lenz was born in Dorpat (nowadays Tartu, Estonia), at that time the Governorate of Livonia in the Russian Empire.

After completing his secondary education in 1820, Lenz studied chemistry and physics at the University of Dorpat.

 He traveled with the navigator Otto von Kotzebue on his third expedition around the world from 1823 to 1826. On the voyage Lenz studied climatic conditions and the physical properties of seawater. The results have been published in "Memoirs of the St. Petersburg Academy of Sciences" (1831).

After the voyage, Lenz began working at the University of St. Petersburg, Russia, where he later served as the Dean of Mathematics and Physics from 1840 to 1863 and was Rector from 1863 until his death in 1865.

Lenz also taught at the Petrischule in 1830 and 1831, and at the Mikhailovskaya Artillery Academy.

Lenz had begun studying electromagnetism in 1831. Besides the law named in his honor, Lenz also independently discovered Joule's law in 1842; to honor his efforts on the problem, it is also given the name the "Joule–Lenz law," named also for James Prescott Joule.

Lenz eagerly participated in development of the electroplating technology, invented by his friend and colleague Moritz von Jacobi. In 1839, Lenz produced several medallions using electrotyping. Along with the electrotyped relief produced by Jacobi the same year, these were the first instances of galvanoplastic sculpture.

Lenz died in Rome, after suffering from a stroke.

        29.09.1954 | Izveidots CERN

        Eiropas kodolpētījumu organizācija (franču: Organisation Européenne pour la Recherche Nucléaire, angļu: European Organization for Nuclear Research), plašāk pazīstama kā CERN, ir starptautiska organizācija, kas nodarbojas galvenokārt ar daļiņu fizikas pētījumiem. Atrodas uz Francijas un Šveices robežas, galvenais birojs atrodas Ženēvā. 1954. gadā to dibināja 11 Eiropas valstis. CERN galvenais uzdevums ir nodrošināt daļiņu paātrinātājus un citu infrastruktūru augsto enerģiju fizikas pētījumiem. CERN atrodas liels datoru centrs, kas veic eksperimentos iegūto datu apstrādi. Šeit ir radīts vispasaules tīmeklis.
