Is the sextant a carthorse in the 21st century? Abstract The purpose of this report is to decide whether the sextant is outdated and effectively useless in the modern age or whether it still has a use in modern navigation. To decide this I explored modern navigation techniques‚ which is mostly done by global positioning systems‚ I researched the way that these work and the methodology behind the use of a sextant. The conclusion that I came to was that modern day sextant use is rare

1.____________________________________________ Solar Energy System Design The largest solar electric generating plant in the world produces a maximum of 354 megawatts (MW) of electricity and is located at Kramer Junction‚ California. This solar energy generating facility‚ shown below‚ produces electricity for the Southern California Edison power grid supplying the greater Los Angeles area. The authors ’ goal is to provide the necessary information to design such systems. The solar collectors

subtropical high has expanded to its largest extent and most pole ward position‚ exerting its influence on subtropical west coasts between 30o and 40o N and S latitude. Subsiding air from the high creates stable atmospheric conditions when coupled with cold ocean currents along these coasts (p. 111‚ ¶ 3). Terre Haute has a mid-latitude continental climate. Ritter explains that rainfall in is fairly evenly

4. Describe the difference in stellar evolution of stars the size of our sun with that of stars 4+ times larger than our sun. Include all of the steps and the causes of each step. A nebula‚ an immense cloud of hydrogen gas and dust‚ condenses into smaller regions of matter. On occasion‚ one of these regions collapses under the force of its own gravitational attraction‚ often triggered by an outside force‚ like a nearby supernova-an explosion of a star. After the collapse of a cloud‚ atoms begin

GG310 OCEANOGRAPHY Evaluate the geological evidence for so-called ‘Snowball Earth’ glacial episodes in the Precambrian and the hypothesis that these episodes were critical in the evolution of complex life. Introduction The hypothesis of Snowball Earth explores the possibility of the Earth’s surfaces having been frozen over during the Cryogenian period. The initial notion was thought to be from the glacial deposits which occurred around the world parallel to the same time frame. This led scientist

reactive oxygen species generated by UVA. Competition for foliate between the needs for cell division‚ DNA repair‚ and melanogenesis is severe under stressful‚ high-UVR conditions and is exacerbated by dietary insufficiency. Outside of tropical latitudes‚ UVB levels are generally low and peak only once during the year. The populations exhibiting maximally pigmented skin are those inhabiting environments with the lowest annual and summer peak levels of UVB. Development of facultative pigmentation

Tundra Climate (E) The tundra is a bleak and treeless place. It is cold through all months of the year Summer is a brief period of milder climates when the sun shines almost 24 hours a day. It has been called "the land of the midnight sun". But even the sun can’t warm the tundra much. The short summer lasts only 6 to 10 weeks. It never gets any warmer than 45 or 50° F. The warmer weather causes a layer of permafrost‚ ice that never goes away in the ground‚ to melt‚ creating bogs and shallow lakes

Gravity varies with latitude. A person weighs .5% more when they are closer to the North and South poles‚ compared to standing by the equator. The earth is not completely rounded and is actually more of a “squashed” sphere; therefore‚ this causes the radiuses of the equator
