which mathematical innovation did the early muslims caliphates achieve

Answers

Answer 1

The early Muslim caliphates introduced Arabic numerals for easier mathematical calculations, invented algebra and trigonometry, and used mathematics in navigation and religious practices.

The early Muslim caliphates achieved several mathematical innovations during what is known as the Islamic Golden Age. One of the most notable contributions is the development of Arabic numerals, which were based on Hindu characters and provided an easier way to work with numbers compared to the Roman numerals. The Abbasids played a significant role in inventing algebra and trigonometry, further advancing these mathematical fields. The Persian mathematician Al-Khuwārizmi, a prominent figure of this era, not only influenced the word 'algorithm' but also authored the algebra treatise 'The Compendious Book on Calculation by Completion and Balancing' around 820.

Besides these mathematical achievements, the Islamic scholars applied their knowledge to geography by creating accurate maps and navigation by making use of the astrolabe. They also ingeniously utilized mathematics in religious practices, such as using trigonometry to calculate the qibla. Their advancements in numerical representation, including a precursor to the decimal point for non-whole numbers, facilitated arithmetic operations that are still relevant to modern computational methods.

Answers

The statement that best describes the effects of the 1851 Treaty of Fort Laramie is: D. The Indians crossed artificial boundaries, setting the stage for conflict.
The 1851 Treaty of Fort Laramie was an attempt to get the various Native American tribal nations to agree on boundaries and to stop fighting with one another, as well as allowing safe travel to settlers traveling the Oregon Trail. The treaty was broken soon after it was made, as the Lakota and Cheyenne peoples battled with the Crow, and further problems followed. A second Treaty of Fort Laramie was signed between the US government and a number of Indian nations in 1868, after the failure of that first treaty.

Final answer:

Naturalization laws and regulations are considered enumerated powers of Congress, as specified within the Constitution. The President does not hold these legislative powers. An example is the Immigration and Nationality Act by Congress.

Explanation:

Naturalization laws and regulations are the enumerated powers of Congress. Enumerated powers are those specifically granted to Congress by the Constitution. Article I, Section 8 of the Constitution outlines the powers of Congress, which includes the authority to establish a uniform rule of Naturalization. This means, as per the Constitution, Congress alone has the power to make laws concerning the process through which immigrants become citizens, not the President. An example of this is the Immigration and Nationality Act (INA) which was enacted by Congress to govern immigration and naturalization.

why was austrian influence greater among the southern german states than among the northern ones? why was austrian influence greater among the southern german states than among the northern ones?

Answers

Here is the answer to the given question above. The Austrian influence is greater among the Southern German states than among the northern ones because, unlike the German Confederation, the North German Confederation was in fact a true state. Its territory consists of the parts of the German Confederation north of the river Main, plus Prussia's eastern territories and the Duchy of Schleswig, but not including Austria and the southern German states.

Austrian influence was greater among the Southern German states due to geographic proximity, religious similarities, historical ties post-Napoleonic Wars, and economic dependencies.

Austrian influence was greater among the Southern German states than the Northern ones due to several interconnected historical and geopolitical factors.

Firstly, the Southern German states like Bavaria, Baden, and Württemberg were geographically closer to Austria, which facilitated more robust political, economic, and cultural interactions. This proximity allowed Austria to maintain stronger diplomatic and military relationships with these states.

Additionally, these Southern states shared religious similarities with Austria, primarily Catholicism, which differed from the predominately Protestant Northern German states. Religious congruity strengthened political alliances and mutual support between the Southern German states and Austria.

Historical ties also played a significant role. For instance, after the Napoleonic Wars, Austria led the German Confederation, and the Southern states often looked to Austria for leadership and stability. This historical context helped solidify Austria’s influence in the South.

Lastly, economic factors cannot be overlooked. The Southern German states had significant trade and economic agreements with Austria, creating dependencies that further reinforced Austria's sway in the region.

1. Read the quote by Raphael Lemkin.

Genocide is the criminal intent to destroy or to cripple permanently a human group. The acts are directed against groups as such, and individuals are selected for destruction only because they belong to these groups.

Raphael Lemkin spoke these words to the United Nations in 1945.

2. On December 9, 1948, in the shadow of the Holocaust and in no small part due to the tireless efforts of Lemkin himself, the United Nations approved the Convention on the Prevention and Punishment of the Crime of Genocide.

Genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such:

Killing members of the group;
Causing serious bodily or mental harm to members of the group;
Deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part;

Answer: This can be found in the United nations Treaty in Article II.

I hope it helps, Regards.

Answers to #1:

Raphael Lemkin's definition of genocide was not accepted until after the Holocaust.

Raphael Lemkin had been studying the problem of mass killings of a people group since the 1920s, in regard to Turkish slaughter of Armenians in 1915.  He coined the term "genocide" in 1944, in reference then also to the Holocaust.  The term uses Greek language roots and means "killing of a race" of people.  Lemkin served as an advisor to Justice Robert Jackson, the lead prosecutor at the Nuremberg trials.  "Crimes against humanity" was the charge used at the Nuremberg trials, since no international legal definition of "genocide" had yet been accepted.  Ultimately, Lemkin was able to persuade the United Nations to accept the definition of genocide and codify it into international law.  In December, 1948, the United Nations adopted the Convention on the Prevention and Punishment of the Crime of Genocide, which made use of a number of Lemkin's ideas on the subject.

#2:   For item #2, you didn't ask a question, so I won't attempt to guess at what question you might have in mind.  The definition as you quote it comes from Article II of the UN's Genocide Convention.  Article III also indicts intention and conspiracy to commit genocide as crimes against international law.  Article IV of that same Convention then puts teeth into the UN's action, saying, "Persons committing genocide or any of the other acts enumerated in article III shall be punished, whether they are constitutionally responsible rulers, public officials or private individuals."

Timbuktu is primarily known for the renowned Djinguereber Mosque and exclusive Sankore University, both of which were founded in the early 1300s during the leadership of Mansa Musa, the most well-known emperor of the Mali Empire.

Timbuktu, which was established around the year 1100 A.D., developed fast from a temporary camp for storing salt and other items to a significant hub for caravan trade. Westbound travelers brought gold to exchange for salt from mines in the east.

After a shift in trading routes, particularly after the visit by Mansa Musa around 1325, Timbuktu flourished from the trade in salt, gold, ivory, and slaves. It gradually expanded as an important Islamic city on the Saharan trade route and attracted many scholars and traders.

Write a paragraph comparing a republic to a monarchical state. Give examples of each type of government from Renaissance Italy.

Answers

A republic is a form of government ruled by an executive and legislature. Sometimes known as the senate; the legislature creates laws for the populace. In a republic government figures are elected. In a monarchical form of government; there is one monarch or ruling figure; the people have no say.

Final answer:

Comparing a republic to a monarchical state in Renaissance Italy, a republic like Florence valued humanism and individual opinions, whereas monarchical states like the Duchy of Milan centralized power in a monarch. Italian city-states contrast with the consolidated monarchies of France, Spain, and England, all contributing to Renaissance advancements in culture.

Explanation:

When comparing a republic to a monarchical state during Renaissance Italy, noteworthy contrasts emerge. A republic is characterized by a form of government where citizens have the power to elect representatives to govern on their behalf. Florence during the early 15th century is an excellent example of a republic, where humanism flourished and the views of individuals were highly respected, embodying the ideals of republicanism. In contrast, a monarchical state is governed by a single ruler, often hereditary, like the Duchy of Milan under the Sforza dynasty, which demonstrated the centralization of power in the hands of a monarch.

Renaissance Italy presents a distinctive landscape of city-states, each with its form of government, ranging from republics like Florence and Venice to monarchical states like Naples and Milan. This contrasts sharply with the more centralized monarchical powers seen in France, Spain, and England. While Italian city-states often practiced patronage and governed through a balance of powerful families and civic institutions, the monarchies in France, Spain, and England led with a more absolutist approach, personified by figures like Louis XI of France and Ferdinand II of Aragon. Nevertheless, both systems contributed significantly to the advancement of new Renaissance ideas and perspectives, leaving an indelible mark on literature, fine art, and architecture.

In Renaissance Italy, Florence was a prime example of a republic with its government based on individual opinions. On the other hand, monarchies were prevalent in other parts of Italy, like the Kingdom of Naples.

The three goals W.E.B. Du Bois stated as part of Booker T. Washington's agenda for black people were: industrial education, accumulation of wealth, and conciliation of the South. However, it is important to note that Du Bois had substantial disagreements with Washington's approach, particularly with the lack of emphasis on civil and political rights, which Du Bois ardently advocated for. Du Bois's educational philosophy emphasized the importance of higher education and political and civil rights as a cornerstone for achieving racial equality. He also talked about the right to vote, civic equality, and education according to ability for African Americans, as well as the idea of developing a leadership cadre through a liberal arts education which he coined as "the Talented Tenth." This contrasted with Washington's focus on vocational training and practical education as a path to economic improvement for black people.
