  • redefining the kilogram

    1540 Words  | 4 Pages

    am is not by any means disregarding hundreds of years of science and tradition, but rather the complete opposite! The redefinition would simply improve the current definition, respecting the old tradition, while using it as a foundation on which to base the new advancements. The new definition would be more exact, more easily calculable, and more reliable. Most importantly, it will eliminate the physical object altogether, building the definition into nature itself and ensuring constant stability

    During the reign of Henry I the foot became official and was engraved on the base of a column of St. Peter’s church in London (Rowlett, R. (2001). A dictionary of units of measurement. English customary weights and measures). He also arranged the yard to be established in England as well. Although, inches, feet, yards etc. measured shorter distances, miles were used to measure much longer distances. This mile was a Roman unit, which was primarily the length of 1,000 paces of a Roman legion. The “pace”

  • The Metric System

    1286 Words  | 3 Pages

    Unlike Present Day, where most scientific groups and people use the standard unit of measurement; the metric system, there used to be a time when a variety of units of measurement were frequently used throughout the world, some units were also measured using the human body. For example length could be measured in numerous ways such as feet, hands, cubits, palms, rods, furlongs and many more. This creation of multiple varying units created an absence in common measurement standards, leading to a lot of

    Biologists study intimate details of the human brain, the composition of our genes, and even the functioning of our reproductive system. Biologists recently all but completed the deciphering of the human genome, the sequence of deoxyribonucleic acid (DNA) bases that may determine much of our innate capabilities and predispositions to certain forms of behavior and illnesses. DNA sequences have played major roles in criminal cases (O.J. Simpson, as well as the reversal of death penalties for many wrongfully

    conducted, the researchers concluded that the detrimental effects of fluoridated water are too significant to ignore (Campbell, 2013); however, the subject base studied had consumed water with an average fluoride concentration of approximately 1.0 ppm. This limitation bids for research to be conducted with other limitations, such as on a subject base in a water system that has an average fluoride concentration of approximately 0.7 ppm. For the purpose of this study, 1.0 ppm

  • History, Theory, and Applications of Capacitors

    discovered, some thirty years after Faraday's work, the SI unit used measuring capacitance was named a farad (F) in his honor. 1F = 1 C / V In words: one Farad is equal to one Coulomb per Volt Since the farad is a large unit of capacitance, most capacitors have units of picofarads (pF) or nanofarads (nF). To this day only one type of capacitor has the ability to store enough energy to warrant measurements using a farad as the standard unit, and this is the super capacitor. A capacitor consists

  • Two Specialists in Cybernetics

    forerunners of cybernetics (i.e., Daniel Danielopolu, Paul Postelnicu), Stefan Odobleja is, undoubtedly, the most important. European recognition of his contribution to the foundations of cybernetics took place twenty years ago when his paper, "Diversity and Unit in Cybernetics" (presented at the Fourth Congress of Cybernetics and Systems in Amsterdam, August, 1978), was received with great acclaim. His work has been used by other Romanian scientists and philosophers like Constantin Noica, Mihai Draganescu

    reported in Poise (P) or centiPoise (cP; 1 cP = 0.01P), or in SI units in Pascal-seconds (Pa.s; 1 Pa.s = 10 P). Dynamic viscosity, which is a function of the internal friction of a fluid, is the quantity used most frequently in bearing design and oil flow calculations. Conversely, it is more convenient to measure viscosity in a manner such that the measurement is affected by the density of the oil. Therefore, kinematic viscosities, in the unit of centiStokes (cSt), are commonly used to characterize

    Chlorine is a greenish yellow gas which combines directly with nearly all elements. Chlorine is a respiratory irritant. The gas irritates the mucous membranes and the liquid burns the skin. As little as 3.5 ppm can be detected as an odour, and 1000 ppm is likely to be fatal after a few deep breaths. It was used as a war gas in 1915. It is not found in a free state in nature, but is found commonly as NaCl (solid or seawater). Table: basic information about and classifications of chlorine. • Name:
