What is a Logarithmic Scale? When and how do we use them? Who initially benefits from knowing them?

Introduction

 

 

                                   

    One Quasar (an extraordinary and perplexing object in the sky) is 16,000,000,000 light-years away from the Earth.  In other word, it is at a distance of 500,000,000,000,000,000,000,000,000 feet. How far is it?  Can you even read it?  Well, as a scientist, we must deal with and represent the distance on a sheet of paper with other objects.  How is this possible?

 

 

 

 For a human being standing next to a house, we can scale them down and it is possible to represent them on a sheet of paper comparatively.  How about a mountain and a human being?  How about a human being against the distance to a moon?

    Well, that is what we will investigate and find a way through this webquest.  You may work in pairs using websites or reading textbooks.  Anytime you wish, use me as a resource or for guidance.
