- The ancient Greek philosopher Aristotle said that objects fall because each of the four elements (earth, air, fire, and water) had their natural place, and these elements had a tendency to move back toward their natural place. Thus, objects that were made of earth wanted to return to Earth, whereas fire, for example, rose toward heaven.

The first convincing mathematical theory of gravity – in which two masses are attracted toward each other by a force whose effect decreases according to the inverse square of the distance between them – was Newton's law of universal gravitation.
Mar 25, 2019 · Everything gravitates toward its natural place in Aristotle's model, and it comes across as fairly consistent with our intuitive understanding and basic observations about how the world works. Aristotle further believed that objects fall at a speed that is proportional to their weight. In other words, if you took a wooden object and a metal ...

Aug 23, 2005 · An argument in Aristotle (Physics 1.4, 187b14–21) is sometimes taken by later writers as evidence that Aristotle allowed for the existence of minima in natural things. Aristotle writes that there is a smallest size of material substrate on which it is possible for the form of a given natural tissue to occur.
In particular, he believed in four elements: earth, air, fire, and water. Empedocles was a physician as well as a philosopher.

May 26, 2006 · 1. Natures and the four causes. Nature, according to Aristotle, is an inner principle of change and being at rest ( Physics 2.1, 192b20–23). This means that when an entity moves or is at rest according to its nature reference to its nature may serve as an explanation of the event.
Thus, Plato and Aristotle attacked Democritus’s atomic theory on philosophical grounds rather than on scientific ones. Plato valued abstract ideas more than the physical world and rejected the notion that attributes such as goodness and beauty were “mechanical manifestations of material atoms.”
Aristotle’s theory of the basic constituents of matter looks to a modern scientist perhaps something of a backward step from the work of the atomists and Plato. Aristotle assumed all substances to be compounds of four elements : earth, water, air and fire, and each of these to be a combination of two of four opposites , hot and cold, and wet ...
