The Great Zimbabwe was a country on the territory of where the modern day nation of Zimbabwe is located. It had access to the Indian Ocean and a great strategic location, especially when it came to trade, as it was an important place in the trade routes on the ocean.
The people of Zimbabwe had a strong economy, and it was largely based on trading, cattle, and crops.
Three very important and very profitable things that the people of Zimbabwe traded were the ivory, gold, and copper. All three being in abundance on their territory, or in the territories in close proximity, and all of them being in high demand and being very well paid for.
Isaac Newton was creative in his use of prisms to show how white light is actually made up of multiple colors. He used logic in the way he presented his arguments rhetorically in order to convince readers of the correctness of his conclusions.
Newton was not the first to experiment with passing light through prisms to determine how light works. French philosopher Rene Descartes had done prism experiments of his own. But Descartes had thought that passing through a prism actually modified the light in order to produce the color spectrum. Newton correctly understood that when light refracted through the prism, it revealed the range of colors that were naturally in the light. He then used a second prism, blocking all but one color, to show that a single color passing through a prism was not modified in color. He also showed--by positioning the second prism differently--how the multiple colors of light could be recombined into white light again.
Newton's 1672 paper on light refracting through prisms established his reputation as a scientist. He continued to study light throughout his scientific career, publishing a larger work in 1704 on <em>Opticks </em>(as they spelled "optics" then).
The constitution explicitly assigns the president the power to sign or veto legislation, command the armed forces, ask for the written opinion of their cabinet, convene or adjourn congress, grant reprieves and pardons, and receive ambassadors.
