Death Of Socrates essays

Death Of Socrates essays In contemporary with the Age of Enlightenment, also called the Age of Reason in France, neoclassical painters used famous works of literature as a source of inspiration for their paintings. The Death Of Socrates (1787; Oil on canvas, 129.5 x 196.2 cm or 51 x 77 1/4 in) by Jacques Louis David, is a perfect example of a neoclassical painter using a famous work of literarue, in this case Platos Phaedo, as his source of inspiration. Platos marvelous work, however, was not completely captured in Davids this painting, instead David looking through Roman lenses chose to focus more on the famous philosophers immortality. In the painting The Death of Socrates, the painter Jacques Louis David, takes a scene from Platos Phaedo and paints it from a Roman perspective. For example the setting of the scene takes place in a chamber that has Roman arches on the windows and an arch in the hallway. In addition there is also a Roman style lamp found behind Socrates. Other than the Roman perspective portrayed by David there is also a distribution of light and dark accents in this masterwork that aids in distinguishing the significance and divinity of Socrates. First of all, the light coming from the windows in the background and the lamp in the background are not the main source of light in this scene. However, the origin of the primary source of light that is emphasizing on Socrates and then on his disciples is unknown. In Davids painting the light that shines on Socrates is brighter than all of the other light sources. This contrast in lighting helps emphasize Socrates godliness. In addition to the lighting contrast, Socrates godliness is also reflected on way his body has been painted. David painted Socrates with an ideally proportioned and athletic body in his painting so that he can depict Socrates as perfect man or a god like man. In addition...

Biography of John Dalton, the Father of Chemistry

Biography of John Dalton, the 'Father of Chemistry' John Dalton (September 6, 1766–July 27, 1844) was a renowned English chemist, physicist, and meteorologist. His most famous contributions were his atomic theory and color blindness research. Fast Facts: John Dalton Known For: Atomic theory and color blindness researchBorn: September 6, 1766 in Eaglesfield, Cumberland, EnglandParents: Joseph Dalton, Deborah Greenups.Died: July 27, 1844 in Manchester, EnglandEducation: Grammar schoolPublished Works:  New System of Chemical Philosophy, Memoirs of the Literary and Philosophical Society of ManchesterAwards and Honors:  The Royal Medal (1826), the fellowship of the  Royal Society of London  and the Royal Society of Edinburgh, honorary degree from the  University of Oxford, associate of the French  Academy of Sciences,Notable Quote: Matter, though divisible in an extreme degree, is nevertheless not infinitely divisible. That is, there must be some point beyond which we cannot go in the division of matter....I have chosen the word â€Å"atom† to signify these ultimate particles. Early Life Dalton was born into a Quaker family on September 6, 1766. He learned from his father, a weaver, and from Quaker John Fletcher, who taught at a private school. John Dalton started working when he was 10 years old and began teaching at a local school at age 12. Within just a few years, despite their lack of higher education, John and his brother started up their own Quaker school. He could not attend an English university because he was a Dissenter (opposed to being required to join the Church of England), so he learned about science informally from John Gough, a mathematician and experimental physicist. Dalton became a teacher of mathematics and natural philosophy (the study of nature and physics) at age 27 at a dissenting academy in Manchester. He resigned at age 34 and became a private tutor. Scientific Discoveries and Contributions John Dalton actually published in a variety of fields, including mathematics and English grammar, but he is best known for his science. Dalton kept meticulous daily weather records. He rediscovered the Hadley cell theory of atmospheric circulation. He believed air consisted of about 80% nitrogen and 20% oxygen, unlike most of his peers, who thought air was its own compound.Dalton and his brother were both colorblind, but this condition had not been officially discussed or studied. He thought the color perception might be due to a discoloration inside the liquid of the eye and believed there was a hereditary component to red-green color blindness. Although his theory about discolored liquid did not pan out, color blindness became known as Daltonism.John Dalton wrote a series of papers describing gas laws. His law on partial pressure became known as Daltons Law.Dalton published the first table of relative atomic weights of atoms of the elements. The table contained six elements, with weights relative to that of hydrogen. Atomic Theory Daltons atomic theory was by far his most famous work; many of his ideas have proven to be either completely correct or largely correct. In fact, Daltons contributions have earned him the nickname, the father of chemistry. According to the Science History Institute, Daltons atomic theories developed during his explorations of meteorology. He discovered, through experiments, that the air is not a vast chemical solvent as  Antoine-Laurent Lavoisier  and his followers had thought, but a mechanical system, where the pressure exerted by each gas in a mixture is independent of the pressure exerted by the other gases, and where the total pressure is the sum of the pressures of each gas. This discovery led him to the idea that the atoms in a mixture were indeed different in weight and â€Å"complexity.† The idea that there are multiple elements, each made up of its own, unique atoms, was absolutely new and quite controversial at the time. It led to experimentation with the concept of atomic weight, which became the basis for later discoveries in physics and chemistry. Daltons theories can be summarized as follows: Elements are made of tiny particles (atoms).Atoms of one  element are exactly the same size and  mass as other atoms  of that element.Atoms of different elements  are different sizes and masses from each other.Atoms cant be further subdivided, nor may they be created or destroyed.Atoms rearrange  during chemical reactions. They may be separated from each other or combined with other atoms.Atoms form chemical compounds by combining with each other in simple, whole number ratios.Atoms combine according to the rule of greatest simplicity, which says if atoms only combine in one ratio, it must be a binary one. Death From 1837 until his death, Dalton suffered a series of strokes. He continued to work until the day he died, supposedly recording a meteorological measurement on July 26, 1844. The following day, an attendant found him dead beside his bed. Legacy Some points of Daltons atomic theory have been shown to be false. For example, atoms may be created and split  using fusion  and fission (although these are  nuclear processes  and Daltons theory does hold for chemical reactions). Another deviation from the theory is that isotopes  of atoms of a single element  may be different from each other (isotopes were unknown in Daltons time). Overall, the theory was immensely powerful. The concept of atoms of elements endures to the present day.
