John Dalton
John Dalton was a great help to modern day chemistry. He was born in 1766 in the small town of Eaglesfield, Cumbria, NW England in the UK. He was a chemist that stated an atomic theory of matter, which is now the theory of modern day chemistry. Besides his theories, he published the first major book of the studies of color blindness; which affected him. The book was published in 1794.
He first stated his theory in 1803: that each chemical element is composed of its own kind of atoms, all with about the same weight. His theory explained why one substance with a curtain amount of mass joins with another substance with the same amount of mass, which forms compounds; this doesn't alway take place. His law also concluded that two solids can not occupy the same space at the same time, although he concluded that a liquid, and a gas can occupy the same space at the same time. His law was the first useful atomic theory of matter.
Another theory he had stated that total pressure let out by a mixture of gasses is the total of the pressures of all individual gasses in the mixture: in other words, he concluded evaporated water exists in air as an independent gas.
Dalton tried his expiriments many times to make sure that his theory was right. To be exact Dalton tried his expiriments about 200,000 times!
Dalton also developed a hypothesis that the sizes of the particles making up different gases must be different.
Daltons talent for recognizing patterns for his expirements data led him from his problem in meteorology. The idea of atoms being fundimental constituents of matter made him realize the importance of the theoretical connection between atomic weights and weight relations. In a easier way of saying this: Dalton was great at recognizing patterns in is work. His idea of atoms being fundimental parts of matter made him realize the importance of the theoretical connection between atomic weights and weight relations. Dalton was the first person to associate the old idea of atoms with stoichiometry.
Daltons atomic theory is based on four ideas:
1. All matter is made up of tiny particles, (A theory said by Newton in the 1680s.
Transformational leadership focuses on increasing employee motivation and engagement and attempts to link employees' sense of self with organizational values. This leadership style emphasizes leading by example, so followers can identify with the leader's vision and values.
The first reason is Socrates’ justice is built on a class system for a country in which everybody is stuck at his or her own spot. This justice does not show the relationship with individuals’ happiness. As long as the ruler rules and workers work, the country is just. The justice of a city requires each individual to keep doing his or her own thing, so he or she will forever stay in one status. Any one class can not override the obligation and the occupation this class requires. So Socrates’s justice theory assumes that an individual is not a single one but a part of social order. An individual in Socrates’ theory does not seek for personal happiness but fulfill the responsibility which the society order
John Dalton, born 6th September 1766, is known for developing the theory of the elements and compounds atomic mass and weights and his research in colour blindness.
...h looking back on it today it might not look like he achieved much in terms publishing a list of only five elements (1803) in comparison to the one hundred and twelve elements we know today. However, at the time it would have been huge, because of the fact that at that time people would have known very little about these elements, also because he was also able to even include their atomic numbers. Dalton also published a second list of elements in 1808, this time there was 20 elements, along with their atomic masses and some combinations of elements. This was an improvement on his first list, but still had quite inaccurate atomic masses and was still a fair way off the 112 elements that we know today. However, this list was improved upon once again in his second volume that was published in 1827 that included 36 elements again along with symbols and atomic masses.
...the first version of the atomic theory, which then later allowed John Dalton to expand on the atomic theory to create a method of discerning atomic weight, was crucial in the development in the table. It was through finding the atomic weight of elements as well as classifying their properties that allowed Mendeleev to create his periodic table and discern possible new elements.
The focus of Socrates at this time in Plato’s Republic is of the ideal city and how it can be traced to the human soul. Socrates believes that the city he has proposed to the other men is perfect in itself. He says that this city possesses four virtues which are the base for the city being perfect. These are the virtues of wisdom, courage, moderation and lastly but most importantly is the virtue of justice. He breaks down the city into classes and he says how each man within the city is responsible for what his life work is. He says that the people of the city whom the mass will see as most educated will be most fit for rule. “You remember the original principle which we were always laying down at the foundation of the State, that one man should practise one thing only, the thing to which his nature was best adapted; now justice is this principle or a part of it.”(433a) It is here that each man concentrates on his own possessions and his own business where we find a just city. He explains that being able to compare social classes within the city is very important because it has produced the important virtue of justice. With Socrates being able to do this he now has to establish a proper dialogue for explaining justice and the soul of an individual.
In Mendeleev’s days the atom was considered the most basic particle of matter. What Mendeleev and other chemist determined was the atomic weight of each element. How heavy its atoms were in comparison to an atom of hydrogen. Mendeleev said, “I began to look about and write down the elemen...
Justice is generally regarded as an important virtue. It is seen as the hallmark of a truly free and fair society, as well as one with a good sense of morality. The average person might see justice as a state where crime is not prevalent, and where individuals are fair and understanding towards one another. However, in order to reach a working definition for justice, one must consider its value and understand the components that make up a greater virtue. Throughout The Apology and Republic, Plato uses Socrates as a mouthpiece, attempting to explore find the true meaning of justice. Throughout The Apology, Socrates dispels commonly held views on the nature of justice and discusses how individuals
The Atomic Theory began in roughly 400BC with Democritus in Ancient Greece and is universally believed to be correct today. Democritus who was born in 460 BC and died 370 BC and is known as the father of modern science. Democritus proclaimed that everything is made up of atoms. He continued his theory to say that atoms will always be in motion, between atoms there is empty space, atoms are unbreakable, there are an infinite number of atoms all different sizes and shapes. He also said that iron atoms are solid and strong and have hooks to lock them together, water atoms are smooth and slippery, salt atoms have sharp jagged edges because of its taste and air atoms are light and spiralling.
John Dalton was a famous chemist born in Eaglesfield, Cumbria, United Kingdom. He lived from 1766-1844. He was important because he made a theory called Dalton’s atomic theory. Dalton’s atomic theory stimulated further research and promoted speculation about the structure of atoms.
The discovery of other more simple concepts associated with isomerism can be dated back to the late 1700s, when a breakthrough in the isolation of a few pure substances occurred. This work was accredited to Carl Wilhelm Scheele, a Swedish-German pharmaceutical chemist, who was able to isolate pure substances that came from the study of animal and vegetable chemistry. His accomplishments lead to the discovery of a variety of organic compounds, each with its own elemental composition. As the years went by and more organic compounds were discovered, several different compounds with the same elemental composition were identified. It was not however, until 1830 that Thomas Thomson, a Scottish chemist and mineralogist from the University of Edinburgh whose work contributed to the expansion of the Dalton atomic theory, brought the question of this concept to the world’s attention. After studying and observing an earlier scientist’s, who went by the name of Berzelius who is one of the founders of modern ...
Our first benefactor of atomic theory was John Dalton, a man later nick-named the "Father of atomic theory" for his contribution of many theories and laws to modern atomic theory. His theories answered many questions of skeptical scientists: elements combine with one another to form chemical compounds and the atom doesn't change, atoms link together in definite proportions, all atoms of any element are all the same, the law of multiple proportions which states that a given mass of one element can combine with various masses of another element (or elements) but always in small whole number ratios, and the law of conservation of matter, matter can neither be created or destroyed, but it can change form.
).on the other hand albert einstain admitted ‘“My new discovery is the result of musical perception”” (Suzuki, 1969,p._90).

“Don’t worry if your theory doesn’t agree with the observations, because they are probably wrong.’ But if your theory does not agree with the 2nd law of thermodynamics then it is in serious trouble”.
His theories and methods formed the future scientific research about the atom that still continues.All the other experiments people has done about the atom could not have been done without his help. He brung back the theory of the atom and got other people after him to keep doing research and contributing to the atomic theory.Without John dalton we probably would not have the same atomic theory and we might not even have it.I think john dalton played one of the biggest parts in the atomic theory.After john dalton there was,J.J. Thomson,Ernest Rutherford,and Niels Bohr.Dalton's most significant work was done between 1795 and 1805, but fame came later—when the importance of his atomic theory was realized. He became a member of the Royal Society in 1822, received its first Royal Medal in 1826, and was honored with a state pension in 1833, among other honors. He died on July 27, 1844, and 40,000 people attended his
