Gregorio Hernandez Mr. Schlinkmann Think and Write The early development of the Periodic Law or table was found by many contributions from a variety of scientists. The contributions led to the discovery and establishment of the Periodic Table. Which help create the Periodic Table we use as of today. The person who created the Periodic Table was a chemist named Dmitri Mendeleev, but not without the help of a few other scientist who helped him get the idea by passing down information they had found. Mendeleev discovered the Periodic Table by trying to organize the elements.
Who discovered it? How did they discover it? It was not Thomas Jefferson and it was not George Washington, so who was it? On the 17th of January 1706, a man by the name of Benjamin Franklin was born.
Chlorine combines with almost every single element, so it cannot be found in nature alone. It was first made by a Swedish chemist Carl Wilhelm Scheele in 1774. This happened when Scheele treated muriatic acid, or hydrochloric acid, with manganese dioxide. (Stwertka 69-70) Scheele mistakenly thought that it contained oxygen.
He discovered that you could mix inorganic substances together and make an organic compound. His original discovery was later disbanded because cyanide was actually an organic substance. His discovery was later approved because of another scientist mixing inorganic substances to form organic compounds. At the time, it was common to ask a question similar to this; could you reproduce an organic compound
Francis Bacon discovered and popularized the scientific method. Francis Bacon practiced law to support himself when his father died. He supported for reform; promoting the consolidation of the U.K., speaking out against religious persecution, and opposing feudal abuses. Francis Bacon’s writings on skepticism, the need for empirical evidence, and the four causes of scientific misguiding set the stage for scientific advancements throughout the Enlightenment period.
He did this with the help of a friend who had given him a clock, which he disassembled for the purpose of learning about the way it functions. With what he found out, he built a different clock, as mentioned above and earned fame. It also helped him learn more about math (Benjamin Banneker (1731-1806), n.d., p. xx) ("Mathematician and Astronomer Benjamin Banneker Was Born," n.d.)
He also invented the Pyrometer, which is a type of thermometer that can measure how hot high fire kilns are on the inside, without opening the kiln door and cracking the pottery inside. He was one of the very first people working on things like this so there was very
Franklin was able to discover electricity and learned how to conserve electricity from a lightning bolt. He published books and pamphlets about his discoveries. Benjamin Franklin also wrote and helped many famous documents. Some documents he helped with was the Stamp Act and the Declaration of Independence. Benjamin himself wrote an entire speech to the president about the constitution and what he thinks about it.

He lost his mother at the tender age of five and inherited a fortune large enough to sustain him through all of his childhood and into early adulthood. Antoine’s father, Jean-Antoine Lavoisier, was a well renowned lawyer in the parliament. He began attending school at the age of eleven.
The Renaissance and Baroque periods of music are two very similar and different eras. The Renaissance which began after the end of the Middle Ages in 1450 and ended the beginning of the 1600s, this is where the Baroque period starts. The beginning of the Renaissance period was compromised of sacred and religious music cultivating from the middle ages. Before the Renaissance period music had to be copied and re-written by hand, which was a very difficult task to do continuously. During the Renaissance period however, printing was invented, which made producing music easier and also changed a lot of other things in other areas. The Baroque period on the other hand, spanning 150 years from the beginning of the 1600s to 1750, was divided into three parts: The Early Baroque period, The Middle Baroque period and The Late Baroque period. While these two eras start right after each other, there are a lot of differences between them, this shows how much music can evolve through time.
