Essays on Physicist

Leona Woods Marshall Libby, who was instrumental in the preparation of the first ever atomic bomb, was an American physicist. She was also part of the research team that built the first nuclear reactor in America. She was mentored by Enrico Fermi, the famous Italian physicist who won the Nobel Prize. She was born in Illinois and completed her BS Degree in chemistry at a young age of 18 (Libby, 1979). Later, Leona wanted to pursue her higher education in physics and approached Robert Mulliken, a future Nobel laureate to become one of his graduate students. He accepted her ...

Radiology, without which it is impossible to imagine modern medicine, was born with the discovery of the penetrating radiation made by German physicist Roentgen. This industry has largely contributed to the development of medical diagnostics. As any other industry, its development was revolutionary and has been infuenced by modern technologies. Today, X-ray diagnostics gets a new development. Using age-old experience of traditional radiographic techniques and armed with new digital technologies, X-ray diagnostics is still a leader in diagnostic medicine. In 1894 German physicist Roentgen (1845 - 1923) launched an experimental study of electrical discharges in the glass vacuum tubes. ...

Ultraviolet light (UV light) is a type of electromagnetic radiation that is located between visible light and X-rays in the electromagnetic spectrum. It is invisible to the human eye, and has a frequency greater than that of visible light but lesser than X-rays. It has a wavelength ranging from about 10 nm to 400 nm (ISO, 2007). UV light is a part of the radiation that comes from the sun. It can also be produced artificially by electric arcs, black lights, tanning lamps and mercury vapor lamps. The name Ultraviolet literally translates to “beyond violet”, as it has a ...

Standardization of “Warmists are holding us to mad ‘greenmail’”

Conclusion: Developed nations should not pay any money to poor countries to help them low-emissions and climate-resistant pathways There is no consensus on the causes of climate change Greenies are willing to ignore Nobel Laureates to achieve their goal Robert Laughlin, a scholar and physicist says that no human activity could harm the planet and politicians insist that climate change is man-made [Premise 1.1 and 1.2 linked]

Every nation including the less developed ones contribute to global warning

DNA and its importance in our lives

Introduction Deoxyribonucleic acid (DNA) is a long linear polymer located in the nucleus of a cell. It is developed from nucleotides and shaped like a double helix. It is related to the transmission of hereditary information from one generation to the second generation. DNA contains the information for the development as well as reproduction of an organism, thereby leading to a normal life. In the year 1953, James Watson, a biologist, and Francis Crick, a physicist, discovered the structure of DNA in a laboratory in England (LEROY, 2003). The structure of DNA helped scientists to know the process ...

Question one

Ernest Rutherford is a renown physicist who is known as the father of nuclear physics due to his enormous contribution in the field of radioactivity. Rutherford discovered the concepts on radioactive half-life which assisted in proving that radioactivity is involved with transmutation of a single chemical element to the other. The physicist also differentiated and named the beta and alpha radiations. Rutherford was the first person to design and undertake highly original experiments that had alternating currents as well as high frequency. In his second paper, which was about magnetic viscosity contained a description of time apparatus ...
