What is the reason behind scientist jagadish chandra bose not being recognized as the inventor of radio?.

Answers

Answer 1

Scientist Jagadish Chandra Bose is not widely recognized as the inventor of radio because he did not apply for a patent for his invention, and his work was not fully recognized by the scientific community at the time.

Jagadish Chandra Bose was an Indian physicist who conducted groundbreaking research in the field of radio and microwave optics in the late 19th and early 20th centuries. In 1895, he demonstrated the transmission of radio waves over a distance of several meters, using a device that he called a "coherer." This was several years before Guglielmo Marconi, who is often credited with inventing radio, conducted his own experiments.

However, Bose did not seek a patent for his invention, and he did not promote his work as vigorously as Marconi did. As a result, Marconi is often given credit for the invention of radio, even though Bose's contributions were significant.

The Kansas-Nebraska Act allowed each territory to decide the issue of slavery on the basis of popular sovereignty. Kansas with slavery would violate the Missouri Compromise, which had kept the Union from falling apart for the last thirty-four years. The long-standing compromise would have to be repealed.

Give an example using current affair in South Africa of why would you choose it and of why you think it's better than others. I need 2 pages please ​

Answers

The choice between violence and civil disobedience to solve social issues is a complex one that should be considered carefully. In South Africa, civil disobedience has been used to challenge the status quo and bring about positive change. It is a method that respects human rights and can lead to a more inclusive and democratic society.

Regarding the debate on solving civic social issues, it is important to consider the context and specific circumstances of each case. Violence and civil disobedience are two opposing methods that have been used throughout history to achieve social change.

Violence is characterized by the use of force and aggression towards individuals or groups that oppose certain ideals or beliefs. On the other hand, civil disobedience is a peaceful way to protest and challenge the status quo by breaking the law in a nonviolent way.

In South Africa, there have been many instances of both violence and civil disobedience to fight against social issues such as racism and inequality. One current example is the protests against the arrest of former president Jacob Zuma.

Some protestors have resorted to violent methods, such as looting and damaging property, while others have chosen civil disobedience by organizing peaceful marches and sit-ins.

Although violence can sometimes bring about immediate change, it often leads to more violence and harm to innocent people. In contrast, civil disobedience can be more effective in the long run by raising awareness and putting pressure on the government to address social issues.

In my opinion, civil disobedience is a better method to solve social issues because it is a peaceful way to bring about change and it shows respect for human rights. It also creates a dialogue and can lead to a more inclusive and democratic society.

However, it is important to note that civil disobedience should be used responsibly and not put people's safety at risk.

In conclusion, the choice between violence and civil disobedience to solve social issues is a complex one that should be considered carefully. In South Africa, civil disobedience has been used to challenge the status quo and bring about positive change. It is a method that respects human rights and can lead to a more inclusive and democratic society.

Which idea was embraced by fascists in europe during the 1920s an

Answers

The idea that was embraced by fascists in Europe during the 1920s was the concept of totalitarianism, nationalism, and the belief in a strong central government led by a single authoritarian leader.

The idea of nationalism and the importance of a strong, centralized state were the key tenets embraced by fascists in Europe during the 1920s. This ideology was used to justify their aggressive and expansionist foreign policies, as well as their oppressive tactics at home.


Totalitarianism refers to a political system in which the government exercises complete control over all aspects of society, including the economy, culture, and individual rights. Fascists believed that this level of control was necessary to create a unified and strong nation.

Nationalism, another key component of fascism, is a political ideology that emphasizes the importance of shared cultural and historical identity, and the belief that one's nation is superior to others. Fascists believed that the success of their nation required the suppression of minority groups and the promotion of the majority's interests.

Lastly, fascists in Europe during the 1920s believed in the necessity of a strong central government led by a single authoritarian leader, often referred to as a dictator. This leader was expected to make swift and decisive decisions for the betterment of the nation, bypassing traditional democratic processes.

In summary, the idea embraced by fascists in Europe during the 1920s was a combination of totalitarianism, nationalism, and the belief in a strong central government led by a single authoritarian leader. These principles allowed fascists to justify their aggressive actions, control their societies, and promote their nationalistic agenda.

Additionally, the Union had control of more factories and transportation systems, allowing for more efficient production and distribution of weapons.

Another factor is the impact of the blockade on the Confederacy, which limited their ability to import resources and materials needed for firearm production.

Answers

The abolitionist movement grew stronger as a result of the Scott v. Sandford ruling was explained by b. The Scotts should be freed, but the decision was later overturned.

African Americans, whether free or enslaved, could not be considered American citizens and, as a result, could not file a claim for their freedom in federal courts, according to the U.S. Supreme Court's famous Scott v. Sandford decision, popularly known as the Dred Scott case, which was made in 1857.  The abolitionist movement, which had been fighting to abolish slavery in the United States, was dealt a devastating setback by this ruling.

It demonstrated how the Supreme Court disregarded African Americans' fundamental human rights and upheld the system of slavery. Although the decision sparked outrage among abolitionists and received widespread criticism, it did not advance their cause. Instead, it strengthened pro-slavery defenders and made it more challenging for abolitionists to succeed.

Why would the white people who burned Greenwood down not want the event in textbooks?​

Answers

Answer: The Greenwood massacre, also known as the Tulsa race massacre, was a violent and tragic event that occurred in 1921 in Greenwood, a prosperous African American community in Tulsa, Oklahoma. During the massacre, a white mob destroyed the entire community, burning down homes, businesses, and churches and killing an estimated 300 Black people.

There could be several reasons why some white people who were responsible for the massacre or who may have supported it would not want the event to be included in textbooks:

Guilt or shame: Some individuals may not want the event to be included in textbooks because they feel ashamed or guilty about what happened. They may not want to be associated with such a horrific event, or they may fear backlash or criticism from others.

Desire to maintain power and control: Some individuals or groups may not want the event to be included in textbooks because it could challenge their power and control over the narrative of history. Acknowledging the massacre would mean recognizing the atrocities committed against the Black community and would challenge the dominant narrative that portrays white people as the heroes of American history.

Efforts to minimize or deny the event: Some individuals or groups may want to minimize or deny the event altogether because it does not align with their worldview or political agenda. They may believe that acknowledging the event would undermine their beliefs or political positions, or they may simply not believe that the event occurred or was as severe as reported.

Overall, the reasons why some white people who burned Greenwood down would not want the event to be included in textbooks are likely complex and multifaceted, involving personal, cultural, and political factors.

Explanation:

Answer:

they wanted to cover up their atrocities, escape justice, and preserve their racial and economic privilege.

Explanation:

the Tulsa race massacre was a two-day-long massacre that took place between May 31 and June 1, 1921, when mobs of white residents, some of whom had been appointed as deputies and armed by city government officials, attacked Black residents and destroyed homes and businesses of the Greenwood District in Tulsa, Oklahoma. The event remains one of the worst incidents of racial violence in U.S. history, and, for a period, remained one of the least-known: News reports were largely squelched, despite the fact that hundreds of people were killed and thousands left homeless.

One possible reason why the white people who burned Greenwood down would not want the event in textbooks is that they wanted to erase the evidence of their crimes and avoid accountability for their actions. For decades, there was no public recognition or official investigation of the massacre. The local newspapers that had covered the story were removed from archives or destroyed. The survivors and their descendants were silenced by fear, intimidation, and legal threats. The state and city governments did not acknowledge or compensate the victims for their losses. The history of Greenwood and its prosperous Black community was largely forgotten or distorted.

Another possible reason why the white people who burned Greenwood down would not want the event in textbooks is that they wanted to maintain their racial supremacy and economic dominance over the Black population. One factor that drove the violence was resentment toward the Black prosperity found in block after block of Greenwood, which was home to what was known as America’s Black Wall Street. The white mob looted and burned down hundreds of businesses, including grocery stores, hotels, nightclubs, theaters, doctor’s offices, and churches. They also killed hundreds of residents and drove thousands out of their homes. By destroying Greenwood, they eliminated a source of competition and inspiration for Black people across the nation. They also prevented the accumulation and transmission of generational wealth that could have shaped and secured the fortunes of Black children and grandchildren.

Therefore, some possible reasons why the white people who burned Greenwood down would not want the event in textbooks are that they wanted to cover up their atrocities, escape justice, and preserve their racial and economic privilege.

Where did German communists take their orders from?

Answers

Answer:

German communists took their orders from the Communist Party of the Soviet Union (CPSU). The CPSU was the ruling party of the Soviet Union and it had a great deal of influence over communist parties around the world. The CPSU provided financial and logistical support to communist parties in other countries, and it also issued directives on how they should operate. German communists were expected to follow the CPSU's lead, and they were often punished if they did not.

The CPSU's influence over German communists was particularly strong during the Cold War. The Soviet Union was seen as the leader of the communist world, and German communists were expected to toe the party line. The CPSU's influence began to decline after the fall of the Berlin Wall in 1989, and it has been virtually nonexistent since the collapse of the Soviet Union in 1991.

Can someone type an essay about berlin,korea,and cuba: how did U.S contain communism?

Answers

Certainly! Here's a brief essay on the topic:

Throughout the 20th century, the United States was heavily involved in containing the spread of communism around the world. This policy was most notably applied in Berlin, Korea, and Cuba, where the U.S. sought to prevent the expansion of Soviet and Chinese influence.

In Berlin, the U.S. and its allies implemented a policy of containment in response to the Soviet Union's blockade of West Berlin in 1948. This policy involved airlifting supplies to the city in order to keep it from falling under Soviet control. The U.S. also established a military presence in West Germany, which served as a deterrent against further Soviet aggression in Europe.

In Korea, the U.S. intervened in the Korean War in 1950 in order to prevent North Korea from spreading communism to the South. The war lasted until 1953, and resulted in a stalemate that left the two Koreas divided along the 38th parallel. The U.S. maintained a military presence in South Korea after the war, and continues to do so to this day.

In Cuba, the U.S. became involved in the early 1960s, following the Cuban Revolution and the rise of Fidel Castro to power. The U.S. attempted to overthrow the Castro regime through a failed invasion at the Bay of Pigs in 1961. This was followed by a naval blockade of Cuba in response to the discovery of Soviet missiles on the island in 1962. The Cuban Missile Crisis was ultimately resolved through a diplomatic agreement between the U.S. and the Soviet Union.

Overall, the U.S. sought to contain the spread of communism through a combination of military, economic, and diplomatic means. This policy was largely successful in preventing the spread of communism to other parts of the world, though it also led to a number of conflicts and tensions between the U.S. and its allies on one hand, and the Soviet Union and its allies on the other.
