Ernest Rutherford Essay Cont Example | Topics and Well Written Essays - 750 words

Ernest Rutherford Cont - Essay Example In 1971, Earnest continued to make contributions in the field of physics through a series of experiments and would later discover that it was possible to disintegrate nuclei of light elements like nitrogen using energy from alpha particles of radioactive materials. Therefore, Earnest was the first to induce an artificial nuclear reaction, and his idea is the basis for nuclear reactions in the modern world for producing energy and weaponry. He is famous for coining the names alpha, beta, and gamma rays in a bid to classify the various forms of rays since the concept was barely understandable in those days (Nobel Media 1). In this case, the scientist made a significant contribution to electromagnetic radiation. Furthermore, Ernest observed that radioactivity of objects reduced with time (Rutherford 17). Eventually, he came up with the term half-life as the time it takes for the radioactive materials to disintegrate thus the scientist was the one who set the laws governing radioactive decay. In addition, Rutherford is the scientist behind the nuclear model of atoms where he inferred that an atom comprise a nucleus that is surrounded by many orbiting electrons and his conclusion is how modern science view atoms (Weisstein 1). Earnest‘s contribution in nuclear physics has contributed to a great deal in the area of modern physics and chemistry (Weisstein 1). The concept of radioactivity, especially the alpha, beta, and gamma rays is the basis for understanding how solar radiation reaches the earth and the overall effect on atmospheric temperature. Earnest found that gamma rays were of high frequencies and if they reached the earths surface, the temperatures could be high and unbearable for the inhabitants (Rutherford 1). In this case, Earnest made an important contribution for the modern scientists to understand how issues like global warming and

People of Lubbock and Recycling Behavior Research Paper - 1

People of Lubbock and Recycling Behavior - Research Paper Example This research paper describes the effective waste management strategies that can be aplied to the people of Lubbock town, United Kingdom. The researcher analyzes human behaviour of the town residents and discusses strategies that can increase the effective waste management in the community. In order to increase recycling rates amongst the residents of Lubbock, the researcher believes a holistic approach, integrating Azjen’s Theory of Planned Behaviour and Barr et al’s Environmental Conceptual Framework is necessary in order to provide a better understanding of environmental actions. The literature presented in this research paper indicates that unit based pricing and variable rate systems are the most effective economic means to reduce municipal waste disposal and increase recycling rates. However, a range of non-economic factors have also been shown to motivate people to recycle, in which effective recycling strategies must be highly convenient for people to use and ac cess. However, Reschovskey and Stone also acknowledge that’s people’s intrinsic and extrinsic attitudes and values towards the environment affect recycling rates. People who express altruistic tendencies and greater environmentally positive attitudes tend to recycle more frequently. To conclude, the researcher states that these findings indicate that policy makers also need to raise people’s environmental awareness in order for them to develop an eco-centric perspective and values towards sustainable waste management issues.
