microsoft word - gs2_m1a.doc module #1: a brief history of science introduction this course will take you on a tour of what i consider to be the most interesting of all human endeavors: science. now, of course, i am well aware that many people (perhaps even you) do not think science is interesting. nevertheless, i do believe that most people’s dislike of science comes from bad curriculum and/or bad teachers, not the subject itself. hopefully, as you go through this course, you will see why i find science so incredibly interesting, and if nothing else, you will at least develop an appreciation for this fascinating field of study. so what is science, anyway? well, the word “science” comes from the latin word “scientia” (sye en’ tee uh), which means “to have knowledge.” it can be generally defined as follows: science – an endeavor dedicated to the accumulation and classification of …

h science is heading today. in the end, then, no one should undertake a serious study of science without first taking a look at its history. that’s where we will start in the course. this module will provide you with a brief history of human scientific inquiry. if you do not like history, please stick with this module. you will start to sink your teeth into science in the next module. without a historical perspective, however, you will not fully appreciate what science is. the first inklings of science (from ancient times to 600 b.c.) some of the earliest records from history indicate that 3,000 years before christ, the ancient egyptians already had reasonably sophisticated medical practices. sometime around 2650 b.c., for example, a man named imhotep (eem’ oh tep) was renowned for his knowledge of medicine. people traveled from all over the middle east to visit imhotep, hoping he …

o was in pain, egyptian doctors would feed the patient seeds from a flowering plant called the poppy. eating these poppy seeds seemed to relieve the patient’s pain. modern science tells us why this worked. poppy seeds contain both morphine and codeine, which are excellent pain-relieving drugs still used today! figure 1.1 natural remedies used by ancient egyptians why was egyptian medicine advanced compared to the medicine of other ancient nations? well, at least one reason was the egyptian invention of papyrus (puh pye’ rus). papyrus – an ancient form of paper, made from a plant of the same name as early as 3,000 years before christ, egyptians took thin slices of the stem of the papyrus plant, laid them crosswise on top of each other, moistened them, and then pressed and dried them. the result was a form of paper that was reasonably easy to write on and store. …

ultures had impressive inventions of their own. around the time that papyrus was first being used in egypt, the mesopotamians were making pottery using the first known potter’s wheel. not long after, horse- drawn chariots were being used. as early as 1,000 years before christ, the chinese were using compasses to aid themselves in their travels. the ancient world, then, was filled with inventions that, although they sound commonplace today, revolutionized life during those times. these inventions are history’s first inklings of science. as you progress through this course, you will see that it is divided into sections. usually, at the end of each section, you will find one or two “on your own” questions. you should answer these questions as soon as you come to them in the reading. they are designed to make you think about what you have just read. these questions are often not very easy …

use those facts to develop explanations of the world around them. as near as historians can tell, that didn’t happen until the 6th century b.c., with three individuals known as thales, anaximander (an axe’ uh man der), and anaximenes (an axe’ uh me’ neez). many historians view these three individuals as humanity’s first real scientists. thales studied the heavens and tried to develop a unifying theme that would explain the movement of the heavenly bodies (the planets and stars). he was at least partially successful, as history tells us he used his ideas to predict certain planetary events. for example, he gained a great reputation throughout the known world when he correctly predicted the “short-term disappearance of the sun.” what he predicted, of course, was a solar eclipse, an event in which the moon moves between the earth and the sun, mostly blocking the sun from view. 4 exploring creation …
