The populations of those lands did not accept Turkish rule. The Turks to them were foreigners with completely different customs, way of life, and language. Intervals when there was no unrest were rare. The Hungarians had thrown off Turkish rule by 1688. Serbia was created by the Serbian Revolution, 1815–1833. The Greek War of Independence, 1821–1832, created modern Greece, which recovered most of the lands of ancient Greece, but could not gain Constantinople. The Ottoman Porte was continuously under attack from some quarter in its empire, primarily the Balkans. Also, on a number of occasions in the early 19th century, American and British warships had to attack the Barbary pirates to stop their piracy and recover thousands of enslaved Europeans and Americans.
When was the Greek War of Independence?
1821–1832


Input: Electric motor
Stepper motors are a type of motor frequently used when precise rotations are required. In a stepper motor an internal rotor containing PMs or a magnetically soft rotor with salient poles is controlled by a set of external magnets that are switched electronically. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it "steps"—starts and then quickly stops again—from one position to the next as field windings are energized and de-energized in sequence. Depending on the sequence, the rotor may turn forwards or backwards, and it may change direction, stop, speed up or slow down arbitrarily at any time.

When are stepper motors most useful?
Output: when precise rotations are required


Input: Article: Napoleon was born in Corsica to a relatively modest family of noble Tuscan ancestry. Napoleon supported the French Revolution from the outset in 1789 while serving in the French army, and he tried to spread its ideals to Corsica but was banished from the island in 1793. Two years later, he saved the French government from collapse by firing on the Parisian mobs with cannons. The Directory rewarded Napoleon by giving him command of the Army of Italy at age 26, when he began his first military campaign against the Austrians and their Italian allies, scoring a series of decisive victories that made him famous all across Europe. He followed the defeat of the Allies in Europe by commanding a military expedition to Egypt in 1798, invading and occupying the Ottoman province after defeating the Mamelukes and launching modern Egyptology through the discoveries made by his army.

Now answer this question: How did Napoleon save the French government in 1795?

Output: by firing on the Parisian mobs with cannons


Article: The United Kingdom has traditionally been governed as a unitary state by the Westminster Parliament in London. Instead of adopting a federal model, the UK has relied on gradual devolution to decentralise political power. Devolution in the UK began with the Government of Ireland Act 1914 which granted home rule to Ireland as a constituent country of the former United Kingdom of Great Britain and Ireland. Following the partition of Ireland in 1921 which saw the creation of the sovereign Irish Free State (which eventually evolved into the modern day Republic of Ireland), Northern Ireland retained its devolved government through the Parliament of Northern Ireland, the only part of the UK to have such a body at this time. This body was suspended in 1972 and Northern Ireland was governed by direct rule during the period of conflict known as The Troubles.

Question: Instead of the UK adopting the federalist model, what did they do?
Ans: UK has relied on gradual devolution to decentralise political power


Here is a question about this article: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.
What is the answer to this question: What is the most efficient yellow phosphor?
****
So... YAG phosphor


Article: In Ancient Indian philosophy, materialism developed around 600 BC with the works of Ajita Kesakambali, Payasi, Kanada, and the proponents of the Cārvāka school of philosophy. Kanada became one of the early proponents of atomism. The Nyaya–Vaisesika school (600 BC - 100 BC) developed one of the earliest forms of atomism, though their proofs of God and their positing that the consciousness was not material precludes labelling them as materialists. Buddhist atomism and the Jaina school continued the atomic tradition.

Question: Around what time did materialism become part of Ancient Indian philosophy?
Ans:
600 BC
