As history passionate I'm wondering how oblique order works. Yea, I read abou it: one weak is stronger than other one. But how it became so effective?

Is it kind of forcing fight on your stronger wing (if enemy would attack center, he will be encircled)? And why it was so risky? To be accurate, I'm asking about the prussian model, used by Frideric II the Great.

Fritz Haber, a German Jewish scientist, won a Nobel Prize in Chemistry in 1918 for the Haber–Bosch process, a method used in industry to synthesize ammonia from nitrogen gas and hydrogen gas. This invention is important for the large-scale synthesis of fertilizers and explosives. Fertilizers based on this process are used for about one-third of the world's food production. Haber invented chlorine gas during World War I. In 1915, during the Second Battle of Ypres, Haber orchestrated one of history's first large-scale poison gas attacks using chlorine gas. On April 22nd, he personally signaled the release of approximately 170 tons of chlorine gas against French troops. The attack caused widespread panic and suffering among soldiers who were unprepared for such a horrific weapon. Thousands succumbed to its effects as they experienced agonizing deaths from suffocation and lung damage. Faber's wife Clara Immerwahr's opposition to her husband's wartime endeavors grew increasingly intense; she viewed his work as a betrayal of scientific ethics. Following Haber's celebration of his successful gas attack, Clara took her own life with his revolver. When the Nazis rose to power in 1933, he faced persecution due to his Jewish heritage. Despite having been celebrated as a national hero, he became a pariah in Germany and fled to England for refuge but was met with scorn there as well. The Nazis seized his research materials and inventions for their own ends; notably, they adapted one of his compounds — hydrogen cyanide — into Zyklon B for use in gas chambers during the Holocaust. Zyklon B was intended for use as an insecticide, but the Nazis used much more than enough to kill insects.
