Nicholas II Of Russia
Nicholas II or Nikolai II Alexandrovich Romanov; spelled in pre-revolutionary script. ( 186817 July 1918), known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer,. was the last Emperor of Russia, King of Congress Poland and Grand Duke of Finland, ruling from 1 November 1894 until his abdication on 15 March 1917. During his reign, Nicholas gave support to the economic and political reforms promoted by his prime ministers, Sergei Witte and Pyotr Stolypin. He advocated modernization based on foreign loans and close ties with France, but resisted giving the new parliament (the Duma) major roles. Ultimately, progress was undermined by Nicholas's commitment to autocratic rule, strong aristocratic opposition and defeats sustained by the Russian military in the Russo-Japanese War and World War I. By March 1917, public support for Nicholas had collapsed and he was forced to abdicate the throne, thereby ending the Romanov dynasty's 304-year rule of Russia (16 ...

Peter The Great
Peter I ( – ), most commonly known as Peter the Great,) or Pyotr Alekséyevich ( rus, Пётр Алексе́евич, p=ˈpʲɵtr ɐlʲɪˈksʲejɪvʲɪtɕ, , group=pron was a Russian monarch who ruled the Tsardom of Russia from to 1721 and subsequently the Russian Empire until his death in 1725, jointly ruling with his elder half-brother, Ivan V until 1696. He is primarily credited with the modernisation of the country, transforming it into a European power. Through a number of successful wars, he captured ports at Azov and the Baltic Sea, laying the groundwork for the Imperial Russian Navy, ending uncontested Swedish supremacy in the Baltic and beginning the Tsardom's expansion into a much larger empire that became a major European power. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, Westernised and based on the Enlightenment. Peter's reforms had a lasting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comet Tails
A comet tail—and coma—are features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. Separate tails are formed of dust and gases, becoming visible through different phenomena; the dust reflects sunlight directly and the gases glow from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye. Tail formation In the outer Solar System, comets remain frozen and are extremely difficult or impossible to detect from Earth due to their small size. Statistical detections of inactive comet nuclei in the Kuiper belt have been reported from the Hubble Space Telescope observations, but these detections have been quest ...

Ukrainian SSR
The Ukrainian Soviet Socialist Republic ( uk, Украї́нська Радя́нська Соціалісти́чна Респу́бліка, ; russian: Украи́нская Сове́тская Социалисти́ческая Респу́блика, group=note), abbreviated as the Ukrainian SSR, UkrSSR, or UkSSR, and also known as Soviet Ukraine, was one of the constituent republics of the Soviet Union from 1922 until 1991. In the anthem of the Ukrainian SSR, it was referred to simply as ''Ukraine''. Under the Soviet one-party model, the Ukrainian SSR was governed by the Communist Party of the Soviet Union through its republican branch: the Communist Party of Ukraine. The first iterations of the Ukrainian SSR were established during the Russian Revolution, particularly after the Bolshevik Revolution. The outbreak of the Ukrainian–Soviet War in the former Russian Empire saw the Bolsheviks defeat the independent Ukrainian People's Republic, after which they fou ...

Ion Inculet
An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons while an anion is a negatively charged ion with more electrons than protons. Opposite electric charges are pulled towards one another by electrostatic force, so cations and anions attract each other and readily form ionic compounds. Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
