explains one of the major social justice issue that is becoming controversial these days: Animal Rights. Scientists are trying to find new vaccines and medical products‚ but you cannot test them on humans right away. We cannot risk human’s life‚ but can we risk animal’s life? In 2005‚ the USDA reported that 1‚177‚566 animals were used in the laboratory‚ excluding mice‚ rats‚ birds‚ fish‚ etc. The scientists mostly failed to make new discovery‚ and even if they did‚ it was not effective because humans and

In 1897 the British physicist Joseph John (J. J.) Thomson (1856–1940) discovered the electron in a series of experiments designed to study the nature of electric discharge in a high-vacuum cathode-ray tube‚ an area being investigated by numerous scientists at the time. Thomson interpreted the deflection of the rays by electrically charged plates and magnets as evidence of &quotbodies much smaller than atoms&quot that he calculated as having a very large value for the charge-to-mass ratio.

Luckily‚ no one lives near the growing lava flow but the many scientists that are stationed there‚ complete with new technologies‚ believe that there might be a separate eruption. “If new lava emerges under the nearby ice cap‚ the meeting of fire and ice could unleash massive floods and belch out a cloud of steam driven

Glenn Seaborg. Stanislao Cannizzaro‚ born in 1826 and died in 1910‚ was an Italian chemist. He presented a method to measure atomic masses and to interpret the results of the measurements. Cannizzaro’s method aided scientists into agreeing standard values for atomic masses. The scientists then searched for relationships among atomic masses and other properties of the elements. Dmitri Mendeleev‚ born in 1834‚ was a Russian chemist‚ and is sometimes considered as the ‘father of the Periodic Table’

The speed of light is a well-established premise in physics. Centuries before‚ it was often heard by scientists like Johannes Kepler and Rene Descartes that the speed of light was infinite‚ having the ability to travel at any distance immediately. A notable physicist named Galileo Galilei was one of the first scientists to ponder this phenomenon of light‚ and how to determine the speed of this unknown. In order to do so‚ Galilei formulates an experiment with an assistant. While standing on one hilltop

Dr Graeme Watt Aristeidis Koliopoulos Ethics in Science Should scientist have a common ethics code like the oath of Hippocrates for the doctors‚ or similar to the oath the lawyers give towards society? In order to answer this question it is necessary to examine the meaning of the words Science and Ethics‚ first independently and then in the context of society. The first step in this process is to define each word. According to Wikipedia “…science refers to a system of acquiring knowledge

that one discovery can lead to a whole new process. Scientists can’t precisely predict exactly where their research might take them. The linear process shown in textbooks does not accurately portray the Scientific Method. It only shows one distinct path starting with purpose and ending with conclusion‚ and does not represent the complexity of a scientific experiment like DNA research. The Scientific Process is always looping back to steps as scientist collaborate‚ develop new questions and use

Do you know what makes King Tut the one of the most famous Egyptian pharaohs? King Tut was one of Egypt’s youngest rulers and his life is closely researched by scientists and historians regarding his sudden mysterious death. Radar scans have aided in DNA tests‚ revealing key evidence surrounding King Tut’s chambers which has lead scientists to believe that there are more hidden chambers to be discovered. King Tut is one of the most famous pharaohs of his day because of his young age. Radar scans help
