Moments of Wonder and Ponder

Photo by Norbert Kowalczyk on Unsplash The first of the sub atomic particle to be discovered in the atom was the electron. Physicists had learned to control and create electrical flows, however, to discover what electricity was, it required the separation of the properties of electricity from the wire or material which was impractical because when electricity flows through the wire or other material that creates an electric charge, it is impossible to separate the two. The method that could be executed in order to separate electricity from the particular materials that hold it was by studying the flow of electricity through a vacuum or near a vacuum. In 1858 Johann Geissler's invention of the improved air pump made it possible to extract sufficient air from a glass tube creating a near-vacuum in the tube. The Crookes tube contained a glass tube with a near-vacuum and a wire that carried along an electric current at one end called a cathode and at the other end, a positively charge...

Dear Supporter The main causes of animal extinction are due to human activities and populated lands. Today the Sri Lankan elephant has been listed as endangered by the IUCN, International Union for Conservation of Nature. Sri Lanka has the highest population of wild Asian elephants worldwide, relatively native to Sri Lanka. The complication of elephant extinction would create a major unstable effect on the Island, causing unbalanced natural ecosystems which result in many other animals' death due to the effect of it. The elephant species have declined in numbers because of human-elephant conflicts causing numerous deaths, injuries, and outrages. The natural environments of elephants are cut down and destroyed for purposes like agriculture, infrastructure, and urbanization which have led elephants to move into agricultural lands feeding on crops and vegetation. This causes a great infuriation for farmers as they rely on income through vegetation, fruits, and many crops. Farmers and ...
