A Survey of the Periodic Table

A Survey of the Periodic TableIt is difficult to appreciate the importance of Michael Addition organic chemistry class without having learned a great deal about the periodic table. As I wrote in my last Organic Chemistry class, chemistry is a science which includes an application of knowledge, information and theory about elements, molecules, atoms, etc., so I encourage you to learn this important subject as soon as possible.The periodic table is a key factor in the study of the nature of chemistry, world history and all other aspects of life. Elements in the same row are the same element. These elements, combined in different ways, can produce different substances and elements.The periodic table has been used since ancient times, with the ancient Egyptians using it to describe the natural world. This gives the table a long history. Ancient man recognized the power of the elements to create different kinds of substances which we recognize today as medicines, foods, minerals, plastics , paint, coal, etc. The ancient Greeks and the Chinese had similar ideas, but unlike the Egyptians, did not think of the periodic table in the same way today.The periodic table was used more widely during the Middle Ages. At that time, it was considered more of a religious artifact than a tool for science. There was a belief that the elements would travel down through different veins through time, thereby passing by many forms and places before finally settling at the bottom of the earth. The periodic table helps us understand this belief, because it illustrates that at each time the earth and its atmosphere have changed, certain elements have either altered their positions or new forms have emerged.Modern scientists, though, still cannot agree on which of the elements should be numbered first. Part of the problem is that different people use different units of measurement. Some people use the International System, while others use the SI, and still others use the U.S. customary uni ts. And then there are those who prefer to use their own unit, perhaps one that makes sense to them personally.In some parts of the world, the concept of the periodic table seems to have been forgotten. For example, the Chinese can use the moon's distance from earth as their unit of measure, and they just as readily use the Chinese values of the number 'one' to identify elements. It is often said that the element found on the opposite side of the earth will be easy to identify with a traditional unit of measurement.I hope you can appreciate the value of learning about the periodic table. It can help you think about chemistry and science in a different way. If you are looking for a topic for your next chemistry class, this would be a good time to introduce this subject to students.

Who Was the Tutor of Alexander the Great?

Who Was the Tutor of Alexander the Great?Who was the tutor of Alexander the Great? Is it possible to say that he was one who did his utmost to enhance the glory of his leader and patron king? Alexander, as a matter of fact, wanted to become the most renowned person in the entire world; and being a brilliant prince who was very independent in character, he needed the guidance of a trusted friend.Perhaps he will want to start living in the palace. The so-called friends, who are near and dear to him, tried their best to support him, but only failed miserably in this particular effort. As a matter of fact, he was surrounded by imposters, who were in fact serving someone else's interest. Since the time when he was in the Olympian Court, he was constantly pushed around by his loyal friends.You may say that he was being humiliated and ridiculed every day. That's true to a certain extent, and for the sake of that, you may think about having another close and trusted friend to guide you. You will then be able to achieve all your ambitions in life. Who was the tutor of Alexander the Great?Once the Olympian ruler had stepped into history, he was proud to be remembered as the son of the queen. She had given birth to him and let him carry the crown on his own. There is no doubt about that. But at the same time, the courtiers of the time, who loved to let him be talked about as a charlatan, didn't let him enjoy the glory of being the child of royalty.They never let him have any wide-ranging discussions on his own and give him proper guidance. And that is the reason why, as a matter of fact, he wanted to turn into a warrior. He needed to carry out all his political and military activities by himself, and that's the reason why, when he reached for his destination, the court was full of spies, who were ready to do anything to eliminate the new young man.When the courtiers knew that they had not done anything, they still hatched their plans to have him assassinated. Some of them talked about forming an army and they planned to march towards Macedonia and assassinate the King there. In fact, they even sent for his mother to offer her help in getting rid of him.In spite of the threats and the plots against him, he resisted, and his mother told him one thing that she would give everything that she had to get rid of him. She said that she would return home to Greece but not before he had attained all his dreams and achieved all his ambitions. When he was about to leave the court, the courtiers tried to persuade him, but he refused. With that, he started walking towards his place of exile.
