This is where Ptolemy was born, in the city established by Alexander the Great.
Alexandria had a famous library that attracted many scholars from Greece. The library was ultimately destroyed and many of records where lost. https://m.youtube.com/watch?v=jvWncVbXfJ0 -
Ptolemy rejects his idea about a heliocentric point of view.
-
-
-
-
-
Muslim scholars mostly accepted Ptolemy’s astronomy
-

-
-
His father was a copper merchant and he died when Copernicus was ten. His mother also died around this time.
-
-
Starting date
He studied math, Greek, Islamic, and astronomy. He had a wealthy uncle who paired for his schooling. While he was attending this school, he began to question the geocentric point of view. This is also when he found the mathematical errors in the equations for epicycles that pointed him towards the heliocentric point of view. -
He developed evidence for the heliocentric view.
-
For the next seven years he worked for his uncle and was able to study space and the cosmos in his free time.
-
-
Copernicus used the tower of a church to make measurements of the stars.
-
This was a book that he wrote about his heliocentric view point and he shared it with his peers.
-
-
He complies all of the things that he has studied and everything that he learned in a book.
-
He published his book about the heliocentric view years after he completed it.
-
Ptolemy‘s views were accepted until Copernicus introduced the heliocentric view again.
-
-
-
-
-
-
-
He also observed Jupiter’s moons.
-
-
-

-
-
Newton made many scientific contraptions in school, instead of socializing with all of the other children.
-
He attended Cambridge to get a mathematics degree. As he learned more about math, he was able to connect science and math better.
-
Ah, yes. The famous story of the apple and how gravity was discovered. This was only one of Newton’s primary discoveries. The other is when he discovered and proved that white light is composed of all colors.
-
This book contains the three Laws of Motions, expands on Kepler’s Laws of Motion, and started the Law of Universal Gravitation. He also observed planets during this theme with a telescope that he made and this furthered his testimonies supporting the heliocentric view.
-
-
He was born in Tobolsk, Siberia, Russia
-
-
Mendeleev returned from his research in Europe. When he got back to Russia, he started teaching at the Technical Institute in St. Petersburg. He also wrote the first book on Organic Chemistry around this time.
-
He started writing his two volumes of the Principals of Chemistry, where he set out to organize and explain the elements. He began with what he called the “typical” elements: hydrogen, oxygen, nitrogen, and carbon
-
-
This year he became known for his diagram of elements, which later became known as the periodic table. His chart also left spots open for elements that had yet to be discovered
-
Marie Curie was actually born as Maria Sklodowska. She was the youngest of five children. Her mother was the headmistress of a school for girls and her dad taught math and physics.
-
This caused a lot of change in her life. She was only ten when this happened. Not only did she lose her mother, but her father also lost his job and he had to rent out rooms in their house to get money.
-
He was born the son of a Protestant pastor.
-
-
She was interested in science. She was a very smart student and she graduated from high school with top grades when she was fifteen.
-
She went to Paris because women could go to college in the school in her country. In Paris, she got to learn from some of the best minds in the era. She signed her name as Marie when she went to the school. She was one of twenty-three women in the school. This was still at the point in time when people thought that women shouldn't study science, but Marie was very dedicated.
-
She passed her exam with the highest marks in her class and was the first woman to get a degree in physics from that school.
-
Scientists all over the world were making lots of scientific discoveries. A German scientists discovered x-ray waves. This would help Marie Curie with her own discoveries later in life.
-
Marie was thinking about going back to Poland, but she met Pierre Curie, who was a French scientist, and they got married. They lived in a small apartment and Pierre worked at a college professor.
-
Marie and Pierre's first daughter, Irene, was born. She also began her work with radioactivity
-
Marie tested lots of different minerals. One of them, which was called pitchblende, was believed to be made up of mostly uranium and oxygen, but Marie found that it gave off much stronger X-rays then they elements usually did. Marie and Pierre worked tirelessly, trying to separate the elements. They discovered radium and polonium and created a term to express how much radiation an element gives off. This term is radioactivity.
-
Marie shared the Nobel Prize in physics with her husband, Pierre, and Antoine Henri Becquerel. She was the first woman to receive a Nobel Prize
-
-
-
He went to help track polar air circulation. This could be done with the help of air balloons. He had always wanted to go on a polar expedition.
-
Wegener really like air balloons. Wegener and his brother, Kurt, set the world record for the longest time aloft in a balloon. That time was 52 hours.
-
Pierre was hit by a horse-drawn carriage on a busy street and died instantly. She struggled after he died. She continued his work and took his place teaching.
-
-
-
She joined the school board and picked up where Pierre had left. A new science was coming to be around this time. That new science was chemistry.
-
-
-
He found that the east coast of South America fit exactly against the west coast of Africa. He started looking for more evidence
-
He wrote a book with Vladimir Koppen. it was called The Thermodynamics of the Atmosphere,
-
Marie was determined to figure out where the elements that she had found went in the newly formed periodic table. She found out and got a Noble Prize for it. She was the first person get two Nobel Prizes. She traveled to Sweden to accept the award, bringing her two daughters with her.
-
-
-
She did this to promote the research on radioactivity.
-
He got more evidence about the continents fitting together and published it in a book called The Origin of Continents and Oceans. He claimed that about 300 million years ago, the continents formed a single mass that he labeled “Pangaea,” a Greek word meaning “whole Earth." He was not the first to express this idea but he was the first to use extensive evidence from different scientific approaches to prove it. He used fossil evidence. He found large-scale geological feature that matched.
-
-
Wegener was scorned and made fun of here, but he just smoked his pipe and listened.
-
He set up yearlong weather-monitoring equipment.
-
-
He died after his birthday when returning from his trip west to the coast with his companion Rasmus Villumsen.
-
She died of a type of leukemia that was caused by radiation.
-
During the war, Hess left the gear that basically graphed the seafloor and he was surprised by what he found. The sea floor was not as smooth as it had been supposed to be. It had canyons, trenched and volcanic mountains. He realized that the Earth's crust was moving apart from one another, so he published his theory in a book.
-
Hess was able to live to see his major theory confirmed and accepted. He helped plan the US space program. He died of a heart attack a month after Apollo 11's successful mission to the moon.
