Maya Creation

Maya Creation The Mayans believe that Mother Earth was a gigantic monster. It was an alligator, toad, and a turtle combined. Above her was a sky with a layer for each planet and spheres of movement for the sun and the moon. Below her was the underworld where heavenly bodies passed when out of sight. All around her were the spirits of rain and thunder. The deities of the food plants and animals attended her. All nature was alive and it was constantly dying and being reborn (Burland 1771).The Mayans are American Indian people who lived in southern Mexico (Miller 'Maya' Grolier). The Yucatan was the center of the Mayan civilization from about the 1st century B.C. ('Yucantan' Grolier). They flourished in Mexico and central America from 250 to 1600 A.D. ('History of Agriculture' Grolier). Their ancestors had crossed the Bering land Bridge from Asia (Miller 'Maya' Grolier). Honduras was once a part of the Mayan Empire.Espaà ±ol: Retrato de Gregorio Mayans y SiscarIt had flourished between 250 and 950 A .D. (Seligson 'Honduras' Grolier). The Mayans also had lived in Mexican states: Yucantan and Chiapas, British Honduras, Guatemala, Honduras, and El Salvador (Burland 1770)By 1200 B.C., they had dominated trade routes. The trade routes extended from the modern Mexico state of Guerrero to Costa Rica (Miller 'Maya' Grolier). The Mayans had constant cultural and commercial contact from other tribes such as the Aztecs. They were with the central and coastal Mexican civilization that had influenced them and influenced other cultures (Harrison 'History of Latin America' Grolier).The Mayans worshiped peace deities (Matthews 45). They also worshiped a creator who lived beyond the sky, and believed it was male and female. Mayans also believed that males were more important (Burland 1771). They explain this with the fact that man came first (Thompson Internet). They also believe in...

Convert Frequency to Wavelength Worked Example Problem

Convert Frequency to Wavelength Worked Example Problem This example problem demonstrates how to find the wavelength of light from the frequency. Frequency vs Wavelength The wavelength of light (or other waves) is the distance between subsequent crests, valleys, or other fixed points. The frequency is the number of waves that pass a given point in one second. Frequency and wavelength are related terms used to describe electromagnetic radiation or light. One simple equation is used to convert between them: frequency x wavelength speed of light ÃŽ » v c, when ÃŽ » is wavelength, v is frequency, and c is the speed of light so wavelength speed of light / frequency frequency speed of light / wavelength The higher the frequency, the shorter the wavelength. The usual unit for frequency is Hertz or Hz, which is 1 oscillation per second. Wavelength is reported in units of distance, which often ranges from nanometers to meters. Conversions between frequency and wavelength most often involve wavelength in meters because thats how most people remember the speed of light in a vacuum. Key Takeaways: Frequency to Wavelength Conversion Frequency is how many waves pass a defined point per second. Wavelength is the distance between successive peaks or valleys of a wave.Frequency multiplied by wavelength equals the speed of light. So, if you know either the frequency or the wavelength you can calculate the other value. Frequency To Wavelength Conversion Problem The Aurora Borealis is a night display in the Northern latitudes caused by ionizing radiation interacting with the Earths magnetic field and the upper atmosphere. The distinctive green color is caused by the interaction of the radiation with oxygen and has a frequency of 5.38 x 1014 Hz. What is the wavelength of this light?Solution:The speed of light, c, is equal to the product of the wavelength, lamda;, and the frequency, ÃŽ ½.ThereforeÃŽ » c/ÃŽ ½ÃŽ » 3 x 108 m/sec/(5.38 x 1014 Hz)ÃŽ » 5.576 x 10-7 m1 nm 10-9 mÃŽ » 557.6 nmAnswer:The wavelength of the green light is 5.576 x 10-7 m or 557.6 nm.

Interwar Period - Dissertation Example The women of Russia were beginning to ask for equality, they wanted the government to appreciate them, and by 1921 women in Russia were once again demanding the government provide them with more bread, as times continued to be rough during the transitional period. However, regardless of whether all of the ideas regarding women were fully realized, the ideas themselves still proved to be radical and influential. Throughout 1917 to 1920, Lenin proclaimed that he sought to provide women with the equality they deserved from the efforts they made during the October revolution. He made his opinion known that, through socialism, the classes would become equal and, as a result, the sexes would as well. Although there were small steps made in creating the equality of women that he spoke about, there were large leaps made in ideology that presented a view of gender equality that remains revolutionary for the time and a model for women’s rights movements.
