POLICE BOX You are an engineer. You have been traveling through the universe, both in time and space in the Doctor Who in his Tardis. You happened to be wandering around in ancient Greece when the Doctor heard the cloister bell ring, signaling an emergency. You weren't able to reach the Tardis in time and the Doctor had to take off without you to save the universe. (It was the Daleks again.) While you wait for the Doctor to return you have been asked to solve an important question regarding density. Unfortunately the Doctor has taken all of his technology with him. The problem You have been given two objects. They are both an irregular lumpy shape with lots of fiddly bits sticking out. Both objects are hard and approximately a kilogram of mass. Although they are different masses. What you have to find a You must find the ratio of mass of object a to object B!, but you do not need to find the actual masses. Besides, telling us the mass in the units of measurement of ancient Greece, Talent, Mna, Stater Drachma and Obol would not be of much use to us. b You must also determine which of two materials is the densest. There is a slight problem. Not only must solve your task with the technology available in 300 BCE, but the has been a terrible earthquake in the area and all the cups, bowls, buckets, and containers of all kinds as well as all weighing scales and their weighs have been destroyed. But hey, you're an engineer! Easy peasy!
What you have to measure with First You have available to you a stick. This is a straight stick of uniform cross section. It is marked with notches at regular (equal) intervals. (Imagine something like a meter stick, but meters have not yet been invented). It is strong enough for whatever you need, it is long enough for whatever you need, and it is divided up into as many divisions as needed. , Second You have a supply of string. The string is very thin, but very strong. (It's as strong as you need it to be.) Oh yes, before you came to visit 300 BCE you were a Boy Scout and you earned your knot tying and lashing merit badge. Oh, and you do have something to cut the string with. Third You have a pool of still water. (Yes, the earthquake is over and it's has stopped shaking).
