Science


             Overall the countries use some form of science for health issues new technology, and for gas, etc. People in society use chemistry in their everyday life. .
             In chemistry there are two major theories. People all over the world didn't have an idea of chemistry, until people started getting better knowledge on chemistry. Chemistry is present in a way through out the world that early humans found the way to eat and protect themselves; this is still going on today. .
             The second theory is presented by Alan Cromer, "he states that science, as we think of it, developed in early Greece, possibly because of the democratic nature of its culture, which included objective inquiry and debate" (Krebs Page 1). "From Greece, science spread to China and India" (Krebs Page 5). There were people from all over the world informing other countries about science, like countries in the west. Chemistry was introduced to the Greece and Egypt. Then after a while the Western Europe found out about science because the other countries had informed them also.
             People back then had little clue on how the universe, or our earth and the elements came to the world. How the earth and universe all started 20 billion years ago, hydrogen was the first one in the earth. It has one proton in its nucleus. Hydrogen is the most common element there is, however hydrogen nuclei and helium atoms both elements carry two protons in their nucleus (Krebs Page 6). .
             As the years went on and people started getting more adjust with chemistry, society had scientists studying a lot of things. For example how to make fire, making fire would keep everyone warm because you were creating heat and light. They had things to make when using fire therefore; people back in the days had the ability to survive. In about 3000BC people learned how to form candles for light, also how fire" make pottery from clay pots."(Krebs Page 7).
