Greenland and Antarctic ice sheets are melting‚ glaciers are disappearing and extreme weather events have occurred more often. All these phenomena are the evidence of the fact that the Earth is warming up‚ they are the cause of global warming. Many scientists and researchers are trying to find a way to reduce the heat that the Earth absorbs. But in order to do that‚ they need to answer one question: What is the main cause of global warming. Is it we‚ humans‚ or is it the sun that causes it? Many debates

emitting carbon dioxide into the earth’s atmosphere. Global warming is an urgent issue; moreover‚ there exists a controversy on whether humanity or nature is the cause‚ and the scientists who consider this a serious matter are entirely correct because humans are at fault. For the past couple of decades‚ researchers and scientists have gone head to head in attempting to figure out if global warming does exist. Some people argue against the point and some people may support it. The facts supporting human

During the Stone Age‚ Stonehenge appeared to become a fashionable place to be buried (Scientists). Burial mounds were found central to the landscape. The area may have been split into a Land of the Living‚ where ceremonial parties were held by relatives‚ and the Domain of the Dead‚ with Stonehenge at its Centre‚ where people were buried (Scientists).

Cory Cress Scientist of a Lifetime Werner Heisenberg was the scientist of a lifetime for many different reasons. Werner contributed to the theory of quantum physics‚ while also discovering allotropic forms of hydrogen and receiving the Nobel Prize for physics in 1932. Werner Heisenberg was a scientist of a lifetime because he thrived to learn as much about quantum physics‚ and other types of physics as possible he attended and worked at five different colleges‚ he also educated other people by

The Skeptical Subjectivist Perspective Many Christians adopt a rigid transcendentalist view on morals. However‚ compared to the other views‚ subjectivist and objective relativist‚ they tend to be closed and unobservant. Paul Kurtz‚ author of Science and Ethics‚ attacks this view by demeaning the close-minded‚ faith-based approach on morals (p. 13). While Christians should retain their biblical‚ faith-based perspective‚ Kurtz has a point when he suggests for us to be more open to observations made

that a genome contains the building blocks of life and without it‚ life would not exist as it is at this very moment? These are the types of questions that spark the interest in the human genome and genetic research. From the beginning of time‚ scientists have always shown great interest in the whereabouts of the human species‚ being that the human species are the most complex organisms living to this present day. Who wouldn’t want to know more about oneself‚ especially if it could be beneficial

case of Jesse Gelsinger. However‚ researchers have begun to use vectors that don’t cause an immune response; such as adeno associated viruses‚ virosomes and liposomes. Scientists have also harvested cells and performed gene therapy outside the body (ex vivo). This method of gene therapy does not cause an immune response and scientists can check whether or not the functional gene has been implanted into the genome. In future‚ it is likely that ex vivo gene therapy will become more common‚ as it is safer

His formation then started when he read the scientific works of Aristotle. Thereafter he shifted from being a natural scientist to a "historian" of science. Kuhn always referred to Aristotle in explaining his approach to the history and philosophy of science. He asks the simple question‚ "How could Aristotle‚ one of the world ’s greatest philosophers‚ be so wrong about so

refuses to believe any part of the global warming theory. Behind both opinions‚ there is often confusion‚ misunderstanding‚ and a general lack of knowledge. The theory that global warming has anthropogenic causes has existed for over a century‚ and scientists have collected evidence on global warming for over fifty years. In spite of the evidence‚ the public generally lives in the dark‚ constantly wondering if global warming is fact or fiction. Global warming is the increase in the Earth’s temperature

late 1940s‚ began with the discovery of the isotopic carbon-14 atom. Following this discovery‚ scientists began to ponder ways to utilize carbon-14 to date previously living organisms. Since scientists knew that living organisms absorb carbon-14 at a constant rate while alive‚ they started to formulate a process to measure C-14 to C-12 ratios in dead organisms. This procedure made it possible for scientists to age an organism using this carbon ratio. To ensure the formula was correct‚ they began to
