Galileo courageously led the way in the battle of science over superstition at a time when superstition was accepted as science. Educated as a mathematician, Galileo had wished to pursue a life within the Church but his parents insisted he attend the University to study medicine. While at the Universities of Padua and Pisa, mathematics became his passion and would go on to teach the subject before leaving to study privately. Until the time of Galileo, Nicholas Copernicus (1473  Ã¢â‚¬â€œ 1543) and Johannes Kepler (1571  Ã¢â‚¬â€œ 1630) among others physics theories discovered by Aristotle (384–322 BC) were still considered fundamentally correct. While still a professor, Galileo challenged these theories, one of which led to the dual ball dropping from a leaning tower located in his hometown. According to Aristotle, heavier objects fall at a greater rate than lighter objects. Galileo disproved this theory. "The reason for one object falling faster than the other had to do with the friction each encounters while moving through the air- two objects of different weight actually fall at the same rate in a vacuum." ("Galileo Drops," 2014) Perhaps even more famous than the leaning tower story is Galileos argument against Aristotles theory that the Sun revolved around the Earth, that it was a geocentric universe. The prevailing theory fit well into the Churchs teachings but it had no intention of allowing a new theory, one that made sense and was presented by a credible, respected and well-known scholar, to become public knowledge. Galileo confirmed Copernicus heliocentric theory that the Earth and other planets do what they actually do, revolve around the Sun. To accomplish this, he modified a telescope, increasing its magnification to 20 times when

Article Critique_Shoe Selection in Safe Light-Industrial Jobs - Essay Example It is a requirement for every worker to use necessary protective equipment properly and at all times in the work place. A light industry that involves numerous workers to attain the high number of products should stress the employer’s responsibility to avoid potential injuries in the workplace. Employers should follow the necessary guidelines and standards provided by certain agency such as the Occupational Safety and Health Administration (OSHA). Hazard assessment is done by identifying the physical and health hazards in every workplace which stand as the first critical step in developing a comprehensive safety and health program. Another factor is choosing the appropriate personal protective equipment for the workers who are the main concern in the industrial job. Right selection of shoe will help to minimize workplace injuries thus, increasing their work productivity. The need for the right shoes is essential for individual’s safety and proper support and comfort. Foot and leg injuries were often due to improper shoe selection and poor knowledge on how to select shoes according to the nature of work. Important outline were made to assist workers in light-industrial job in choosing the right shoe particularly in using a heavy-duty leather shoes. The primary idea to consider is to always measure feet before selecting new shoes because feet may change in size over time due to activities that stretches feet and also due to aging. Next, measure feet while standing because standing for long period of time can stretch feet thus, selecting slightly larger shoes can help minimize foot pain later on. Always measure both feet also then select shoes that fit the larger foot if there is slight discrepancy on both size of feet. It is significant as well to buy shoes late in the afternoon for the reason that feet stretch regularly during the course of the day. Upon purchasing, it is a must to spend a few minutes walking while wearing both shoes to make a
