Leonardo DaVinci essays

Leonardo DaVinci essays Throughout history there have been many people who have affected the way we live today. Some of these people have devised laws, created machines, or sculpted artwork. Leonardo DaVinci is one of these people. He was a painter, sculptor, inventor, musician, architect, scientist, and military engineer. Leonardo DaVinci was born on April 15, 1452 in the town of Vinci. At the age of nineteen he traveled to Florence to be an apprentice in the studio of Verrocchio. While he was there he began his painting career. His most famous pieces of works are The Last Supper, Madonna and Child with St. Anne, Mona Lisa, and Self-Portrait. DaVinci also painted the Battle of Anghiari, the Leda. These two pieces of work are not very famous, but they are most important. Sculpting was a pastime that DaVinci cherished. His two great sculptures are the giant equestrian statue of Francesco Sforza and the monument for Marshal Trivulzio. Both of these sculptors were not finished. Throughout his life he invented many objects. DaVinci did not build many of the things he drew. He compiled all of his drawings in the Codex Madrid. Many people discovered his drawings and created replicas of his works. Leonardo taught and created music. He studied the works of the drum. He was very interested in improving the rhythm of drums. He invented the viola organista which was a piano that had a belt of moving hair that went across the strings. This was the most complicated instrument he created. Leonardo is a contributor to the works of architecture. He devised the arch and how the different parts of the arch could handle different amounts of weight. He also researched how a bar or spring acted when they were under stress. Leonardos favorite topic to study was anatomy. He was most curious in the movement of creatures. He studied the...

Difference Between Chemistry and Chemical Engineering

Difference Between Chemistry and Chemical Engineering Although there is overlap between chemistry and chemical engineering, the courses you take, degrees, and jobs are quite different. Heres a look at what chemists and chemical engineers study and what they do. Chemistry vs Chemical Engineering in a Nutshell The big difference between chemistry and chemical engineering has to do with originality and scale. Chemists are more likely to develop novel materials and processes, while chemical engineers are more likely to take these materials and processes and upscale them to make them larger or more efficient. Chemistry Chemists initially obtain bachelor degrees in science or arts, depending on the school. Many chemists pursue advanced degrees (masters or doctorate) in specialized areas. Chemists take courses in all major branches of chemistry, general physics, math through calculus and possibly differential equations, and may take courses in computer science or programming. Chemists typically take core courses in the humanities, too. Bachelor degree chemists usually work in labs. They may contribute to RD or perform sample analysis. Masters degree chemists do the same type of work, plus they may supervise research. Doctoral chemists do and direct research or they may teach chemistry at the college or graduate level. Most chemists pursue advanced degrees and may intern with a company before joining it. Its much more difficult to get a good chemistry position with a bachelors degree than with the specialized training and experience accumulated during graduate study. Chemical Engineering Most chemical engineers go with a bachelors degree in chemical engineering. Masters degree a popular, while doctorates are rare compared with chemistry. Chemical engineers take a test to become licensed engineers. After obtaining enough experience, they may continue to become professional engineers (P.E.). Chemical engineers take most of the chemistry courses studied by chemists, plus engineering courses and additional math. The added math courses include differential equations, linear algebra, and statistics. Common engineering courses are  fluid dynamics, mass transfer, reactor design, thermodynamics, and process design. Engineers may take fewer core courses, but commonly pick up ethics, economics, and business classes. Chemical engineers work on RD teams, process engineering at a plant, project engineering, or management. Similar jobs are performed at the entry and graduate level, although masters degree engineers often find themselves in management. Many start new companies. Job Outlook for Chemists and Chemical Engineers There are numerous job opportunities for both chemists and chemical engineers. In fact, many companies hire both types of professionals. Chemists are the kings of lab analysis. They examine samples, develop new materials and processes, develop computer models and simulations,  and often teach. Chemical engineers are the masters of industrial processes and plants. Although they may work in a lab, youll also find chemical engineers in the field, on computers, and in the boardroom. Both jobs offer opportunities for advancement, although chemical engineers have an edge because of their broader training and certifications. Chemists often pick up postdoctoral or other training to expand their opportunities.
