The modern day society is technologically oriented, with virtually every activity being conducted with the help of various forms of technology. The implication is that the world has seen a massive rate of large-scale production of technology devices. Estimates point out that close to 50 million tons of e-waste are produced globally (Lepawsky & Mcnabb, 2010). The developed countries are the primary producers of this waste, with the role of doing away with the waste left to the poorer developing countries. In the US and Canada for example, close to 80% of all electronic waste is exported to Asia and ...

Question one

Ernest Rutherford made remarkable contributions towards radioactivity and the nature of the atom. He was the first man on earth to discover that atoms have a small nucleus that is charged and its surrounded by space which is circled by very tiny electrons. This was what became to be known as the planetary model or Rutherford model of the atom. Rutherford collaborated with Fredrick Soddy on research on transmutation of elements. The two researched in X-ray effects based on conductivity of gasses ("Ernest Rutherford: Father of nuclear science," 2014). This is where they came up with the ...

Ernest Rutherford and his contribution in radioactivity

Ernest Rutherford is termed as the Father of Radioactivity and nuclear science. Rutherford, who born in 1871 and passed on in 1937, discovered alpha and beta rays. He set forth the law of radioactive decay, identified the alpha particles as helium nuclei. Rutherford postulated the nuclear structure of an atom. His contribution to Radioactivity came from an experiment he demonstrated by firing alpha particles into gas atoms where few particles were seen to deflect. This implied a dense, positively changed central region of an atom contained an atomic mass (Dardo, 2004). Figure 1. Top: expected results, alpha particles passing ...

Introduction

The following discussion entails three questions, which are all based on radioactivity with respect to geology. The three questions are further subdivided into three subtopics: Biography of Ernest Rutherford, weathering, and practical consultation.

One of the most recognized personalities in the world of discovery is Ernest Rutherford. This is due to his efforts in chemistry-related research which led to a number of discoveries. Ernest carried out his education mainly in New Zealand, where he was born and brought up. At first, Rutherford did research into the magnetic properties of iron when exposed to high-frequency oscillations. This made him one ...
