Dmitri Mendeleev
By: _Kandalynn Naidl_
My Chemist: Dmitri Mendeleev
“No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments”,said Dmitri Mendeleev. This quote inspired me, and told me to slow down not to rush, to do things in sections. This made me want to pick Dmitri Mendeleev. As soon as I searched him up, the other chemists were ok, I mean a little interesting, but when I read his biography and many of his famous quotes,v For Ex: “ No one nor anything can silence me,” he popped out to me and reminded me of myself,because if something isn’t right or I don’t like something I will stand up and no one can stop me, I am my own person and have my own voice.

Dmitri died on February 2, 1907 in St.Petersburg. Dimitri’s mother’s name is Maria Dmitrievna Mendeleeva, and his father’s name is Ivan Palovich. Dmitri was the youngest of 14-17 children. Unfortunately when Dmitri was just finishing high school, Dmitri Mendeleev’s father died. Now as a widow, and her glass factory burning down, his mother took him and his sister to their cousin’s house,(By now all of the other kids had grown up and “left the nest”). His mother told the cousin how Dmitri needed to go to school, the cousin disagreed and kicked them out of his house. Three months later Dimitri’s mother died, and soon after his sister came down with tuberculosis. All alone, he left for St.Petersburg …show more content…
He predicted the existence and properties of new elements and pointed out accepted atomic weights that were in error. This organization exceeded attempts at classification by Beguyer de Chancourtois and Newlands and was published a year before the work of Lothar Meyer.
In my opinion, Dmitri Mendeleev was amazing, without him we would not have our periodic table or almost any sense of these elements of ours. I also think that without him we would not have a solid look at chemistry.
In total conclusion, Dmitri Mendeleev was a man of wonder and patience. He had a brain like no one else and the ability to ponder. Mendeleev was one of the first modern-day scientists, in that he did not depend completely on his own work but rather was in correspondence with scientists around the world in order to receive data that they had collected. He then used their data along with his own data to arrange the elements according to their properties. Dmitri Mendeleev got a Nobel Peace Prize in Chemistry for his discovery of the periodic
Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted
Primo Levi’s personal relationship to his profession as a chemist shows that philosophically and psychologically, he is deeply invested in it. His book THe PeriOdic TaBLe shows that his methodology cannot be classified as either purely objective or purely subjective. He fits into the definition of dynamic objectivity given by Evelyn Fox Keller in her book Reflections on Gender and Science.
Mendelsohn as a Master-Craftsman in the Art of Instrumentation Mendelsohn wrote the Hebrides overture in the summer of 1829 in response to seeing and walking in the Hebrides and in paticular visiting Fingal's Cave on an island in the outer Hebredies. Like Mozart before him, he was regarded as a child prodigy and composed several works before he was seventeen. Therefore when we consider the question posed, we must acknowledge Mendelsohn set about writing his concert overture with an esteemed background. The concert overture has many different forms but Mendelsohn used Sonata form for his Hebrides overture (a common decision to make in this Classical period). It could be argued that Sonata form is indicative of Mendelsohn's relative conservatism as it has a fairly strict pattern to follow, both in terms of form, key and temperement: It is clear that Mendelsohn did indeed use three contrasting passages with the addition of the 52 bar long Coda (normally a more brief concluding passage at the end of a work).
On September 9, 1828, their fourth son, Count Leo Nikolayevich Tolstoy, was born on the family’s estate of Yasnaya Polyana. The estate (also spelled as Iasnaia Poliana) was located in the province Tula, approximately one hundred miles south of the Russian capital, Moscow. At the age of two, the Tolstoy home had transformed after the death of his mother, and his father asked his distant cousin Tatyana Ergolsky to take charge of the children and act as a governess. When his father’s death eventually came at the age of nine, the legal guardianship of the five children were given to their aunt, Alexandra Osten-Saken. She was described to be a woman of great religious fervor from which the radical beliefs of Tolstoy’s wer...
Our aim is to portrait the character of Dmitry Dmitrich Gurov, in the context of the story, extracting those elements that are characteristic of the period in which Chekhov wrote the story. True love is a reason for everything, even deleting the laws of life. People's mistakes and weaknesses are part of life and, without contradictions, the world would not have evolved.... ... middle of paper ...
The Five, The Mighty Handful, and The New Russian School all depict the five Russian composers who came together in 1856-57 in St Petersburg. Their ultimate goal was to portray and produce a Russian style of music , and this is exactly what they would accomplish. Though one of "The Five" goes farther than this with his works, this being Modest Mussorgsky. Mussorgsky was a composer born march 21st 1839, with one of the most controversial names and spellings of a name. He was born to wealthy land owners and was raised for the military life. Studying piano at a young age in St. Petersburg, then later arriving at a cadet school.
Biographical Information: Leo Tolstoy was born into an aristocratic family in 1828. He lost both his parents at a young age, and was sent to live on the family estate with his siblings. The estate, Yasnaya Polyana, was located 130 miles from Moscow. This isolation from the aristocracy is truly what set Tolstoy a part from his peers. He cultivated a genuine love and appreciation for the peasants (surfs) that lived on his family’s land. As he grew up he became a deeply moral person, and found it difficult to take part in the socially acceptable debauchery of his peers.
Evidence: Joseph Stalin was the son of a poor shoemaker from a backward province with a significantly low education. Stalin had always had a place for faith in the destiny of the Russian social revolution and an incredible amount of determination to play a role in it. Stalin’s rise to power was remarkable and deadly, yet in an unexplainable twenty-nine years of leadership he turned Russia into a highly industrialized nation. Stalin was a tyrannical ruler who played the most significant role in shaping the direction of Europe at the end of World War II in 1945. He went from a young revolutionist to an absolute leader of Soviet Russia.
Chekhov was born in Taganrog, Russia in 1860 to a woman named Yevgeniya and a man named Pavel. His father, who shares the name of the bishop, is described as being “severe” and sometimes went as far as to chastise Chekhov and his siblings (Letters
Born in Saint Petersburg, Russia on September 25, 1906, Shostakovich was the second of three children born to Dmitri Boleslavovich Shostakovich and Sofiya Vasilievna Kokoulina. His father was of Polish descent but both his parents were Siberian natives. Dmitri was a child prodigy as a pianist and composer. He began taking piano lessons from his mother at the age of nine. He displayed an incredible talent to remember what his mother had played at the previous lesson and would get caught pretending to read the music, playing the music from his last lesson instead of what was placed in front of him.
Dostoevsky’s St. Petersburg is a large, uncaring city which fosters a western style of individualism. As Peter Lowe notes, “The city is crowded, but there is no communality in its crowds, no sense of being part of some greater ‘whole.’” Mrs. Raskolnikov initially notices a change in her son marked by his current state of desperate depression, but she fails to realize the full extent of these changes, even after he is convicted for the murder. The conditions and influences are also noticed by Raskolnikov’s mother who comments on the heat and the enclosed environment which is present throughout the city. When visiting Raskolnikov, she exclaims "I'm sure...
Dmitri Mendeleev was one of the most famous modern-day scientists of all time who contributed greatly to the world’s fields of science, technology, and politics. He helped modernize the world and set it farther ahead into the future. Mendeleev also made studying chemistry easier, by creating a table with the elements and the atomic weights of them put in order by their properties.
Tolstoy's eventful life impacted his works. Leo Nikolayevich Tolstoy was born into a family of aristocratic landowners in 1828 at the family estate at Yasnaya Polyana, a place south of Moscow. His parents died in the 1930s when he was very young so his aunts raised him with an upper middle class lifestyle. His aunts were very important to him and when they died, he made them live on forever as characters in his stories (Alexander 16). While his aunts were still alive, they hired tutors to teach him out of Tolstoy's home (Tolstoi). After a few years of wandering about Russia, he recommenced his studies at sixteen years old at Kazan' University to study law and oriental language but preferred to educate himself independently and in 1847, he gave up his studies without finishing his degree (Troyat 28).
