They opened new areas of the country to explore!Hope this helps a lot!:)
In 1830, they took the state of Georgia to court in a case that challenged Georgia's jurisdictional claims directly. In Cherokee Nation v. Georgia, the Cherokees sought an injunction against Georgia's attempts to implement its act of 1828 asserting sovereignty over Cherokee lands.
IN their last spring offensive of 1918, also known as <em>Kaiserschlacht </em>(Kaiser's Battle) or <em>Ludendorf f Offensive, </em>the German Imperial Army poured all its resources, including troops recently freed from the Eastern Front as a result of the Russian capitulation, and came close to achieve its goal of taking Paris in order to force the Western Allies to negotiate advantageous peace terms to Germany before the United States flooded the battlefields with men, equipment and supplies.
On March 21, 1918. the Germans launched four simultaneous offensives along the western Front: Operations <em>Michael, Georgette, Blücher-York</em> and <em>Gneisenau.</em> Their goal was to run over the Allied troops through the extensive use of assault troops leading the attack of the regular troops. Assault troops (<em>Stosstruppen</em> in German) developed special tactics using small numbers of troops in order to infiltrate through the enemy lines, open corridors through the barbed wire and selectively eliminate machine gun nests and snipers. allowing the bulk of the regular troops to easily assault and take the enemy's first lines of defense.
Operation Blücher-York came as close to Paris as the Marne Offensive of 1914, but a worsening lack of supplies and heavy casualties sustained by the Germans prevented them from achieving their main goal of crushing the enemy forces in order to force the Allied powers to negotiate peace in spite of a relatively large gain of territory. By July 18, the Spring Offensive was ordered to an end by the German High Command, and the arrival of a great number of fresh U.S. troops the next month decisively turned the tide of the war on the Allied side.
Enrich fermi was a scientist and a physicist .He discovered nuclear fission and he led several tests releated to the use of nuclear power and his work was mostly on induced radioactivity by neutron bombardment and the discovery of transuranic elements or a nuclear reactor .His new find followed Marie Curies and Joliot’s discovery of artificial radioactivity .At age 14 he lost his brother from a minor throat surgery accident.In order to escape the pain of losing his brother ,Fermi buried himself in books about physics that fascinated him and soon got him into college with an entrance exam essay that was judged worthy of a doctorates degree .So you could say that his own loss of his brother motivated him to start making discoveries of his own in physics and on experimenting with neutrons. Hope this helped !
No............... hope that helped
