Examples of relative dating and absolute dating

Among the important theories Newton introduced were the laws of motion that govern the way objects move through space, including the law of universal gravitation, and the foundation for calculus.In other words, most people consider Newton a genius, and scientists still apply his ideas to everyday circumstances.The age of the fossil must be determined so it can be compared to other fossil species from the same time period.Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.Newton included in the "Principia Mathematica" a scholium, or an appendix of explanatory notes, and in it he defined several important principles, including the idea of absolute time.Although he understood that clocks weren't perfect and measuring time was subject to human error, Newton believed in an absolute time that was similar to a universal, omnipotent God-like time, one that was the same for everyone, everywhere.In fact, someone can be completely unskilled at doing something, yet still have a comparative advantage at doing it! Michael Jordan has an absolute advantage at basketball.For all I know, Michael Jordan may also be the fastest typist in the world, giving him an absolute advantage at typing, too.

Having a comparative advantage is not the same as being the best at something. Someone who is the best at doing something is said to have an absolute advantage.

If you’re not 6 feet tall or taller, then you may as well just resign yourself to a sexless life of Napoleon jokes.

Of course, short is relative; what we consider “average” height varies depending on geographic locale and someone who’s 5’6″ would consider someone who’s 5’9″ (the average for American men) to be lucky.

Someone may have an absolute advantage at producing every single thing, but he has a comparative advantage at many fewer things, and probably only one or two things.

(In Jordan's case, both basketball and also as an endorser of Nike.) Amazingly, everyone always has a comparative advantage at something. Suppose you and your roommate want to clean the house and cook a magnificent Chicken Kiev dinner for your friends one night.

If, instead, his secretary does the typing, the secretary gives up an alternative secretarial job—or perhaps a much lower salary playing basketball. The secretary, not Michael Jordan, has the comparative advantage at typing!
