One of the reasons why the black death was so deadly was likely: that the yersinia pestis bacterium of the middle ages was parti

cularly virulent. that people were afraid to visit doctors for treatment. that the great famine had weakened many people's immune systems. that most people contracted scarlet fever along with yersinia pestis. that it was regularly used as a form of biological warfare.

The Black Death is considered as the deadliest pandemic in history. There were four main forms of this plague namely: bubonic, pneumonic, septicemic and enteric plague. It wiped out around 200 million people from  Europe and Asia. It was caused by yersinia pestits, a type of bacteria transmitted through flea bites or inhalation. One of the main reasons why the plague spread quickly was the terrible health condition of the city dwellers due to poverty and malnutrition. The great famine of 1315 struck many parts of Europe and it lasted for almost seven years. The famine ultimately weakened the immune system of the dwellers in the cities.

Who discovered Mars? When? How? Where?
Ray Of Light [21]




Tycho Brahe

1609
Johannes Kepler (1571 - 1630), a student of Tycho Brahe, publishes Astronomia Nova (New Astronomy), which contain his first two laws of planetary motion. Kepler's first law assumes that Mars has an elliptical orbit, which was a revolutionary idea at the time. Until then, the classical belief held that a circle was perfect, and therefore all orbits must be circular.

1609
Galileo Galilei (1564 - 1642) observes Mars with a primitive telescope, becoming the first person to use it for astronomical purposes.

1659
The Dutch astronomer Christiaan Huygens (1629 - 1695) draws Mars using an advanced telescope of his own design. He records a large, dark spot on Mars, probably Syrtis Major. He notices that the spot returns to the same position at the same time the next day, and calculates that Mars has a 24 hour period.

1666
Giovanni Cassini (1625 - 1712) observes Mars and determines that the rotational period, or length of one Mars day is 24h, 40m.

1672
Huygens is the first to notice a white spot at the south pole, probably the southern polar cap.

1698
Huygens publishes Cosmotheros, which discusses what is required of a planet to support life, and speculates about intelligent extraterrestrials. This is one of the first published expositions of extraterrestrial life.

Historical Perspective...


The Trial of Galileo

The 1600s were not an easy time in which to study science. The church was a powerful institution and had its own ideas about the nature of the universe. Galileo was a beliver in the Copernican theory that the solar system revolves around the sun. He was advised by Cardinal Bellarmino to be cautious and not to imply the the Copernican theory were real. He published a book, Siderius Nuncius (Starry Messenger) which was considered controversial and in opposition with the ideas of the Roman Catholic Church, and was arrested and tried in the Inquisition. Galileo was found guilty of heresy and was sentenced to life imprisonment and forced to recant. In secret, he wrote another book, which was smuggled out of the country and published in France. His work is now considered the foundation of modern physics.

One post-war fact about the United States that created tension with the USSR was the United States
Rashid [163]

<em>The United States had a democratic government.</em>

Explanation:

The United States and the USSR had little to no trust for each other and that was because they both wanted two entirely different things...

The United States focused on freedom and having a democratic government. Americans wanted to be able to choose their future leaders by voting, while also having the option of overruling them if they abused their power or did not do what was in the benefit of the people.

The Soviet Union wanted communism, where essentially the government has control over everything. The USSR not only wanted this, but they wanted worldwide communism and to keep expanding.

While both of them wanted different things, it was hard to get along and come to terms with each other. They both wanted to expand completely different ideas and ideologies.
