Archimedes
He discovered that you have to find the volume, mass, and density of something
The MAYANS discovered the concept of zero:)
Pierre de fermat developed the number theory but was not found true until someone discovered and took place as the founder.
The concept of real numbers was not invented or discovered by any one person or country. Rather, the concept was improved gradually, over the course of several centuries.

Archimedes
The first person who had to carry something.
IQ in the modern world was first recognized as a concept in 1904.
The first concept of propellers was invented by Leonardo da Vinci in the 1600's
Claude Bernard first talked about the concept but it was really not discovered.
Archimedes discovered density in 265 BC, when he was only 22. He discovered density when he was taking a bath. He discovered that the deeper he went he weighed less and the more the water ran out.
The concept of density was invented, not discovered. It was invented by thinkers who needed a way to describe the weight of a substance that depends only on the substance, and not on how much of it you have.
Unknown persons, many thousands years ago
Density per pound is a meaningless concept.
Man applies the concept of density in many ways. One way is by designing ships and submarines that will float on water. If the density of the object is less than the water's density, the object will float, but if its density is less than the density of water, it will sink.
Density. Its considered a physical property because of the amount of mass/volume. Its an intensive physical property because you can measure density of solution without changing its chemical identify, it observable. ... Because a material that expands takes up a larger volume and it density decreases.Dec 10, 2014
