Are mathematicians all Platonists? **No, pretty far from it**. Platonism is sometimes called Platonic realism. Some writers distinguish between Platonism, as saying that mathematical objects exist, and realism, which says that mathematical facts are in some sense objective.

## What is geometry according to Plato?

Geometry is **a body of truths about real things**. But perceptible things, to which geometry is applied, do not instantiate geometrical properties and relations, because of their imperfections. So geometry is not true of perceptible things.

## How did Plato contribute to geometry?

Plato the mathematician is perhaps best known for his **identification of 5 regular symmetrical 3-dimensional shapes**, which he maintained were the basis for the whole universe, and which have become known as the Platonic Solids: the tetrahedron (constructed of 4 regular triangles, and which for Plato represented fire),

## Is math a Platonic form?

Similarly, **a form of modern Platonism is found in the philosophy of mathematics**, especially regarding the foundations of mathematics. The Platonic interpretation of this philosophy includes the thesis that mathematics is discovered rather than created.

## What type of philosophy is Platonism?

Platonism is the view that there exist such things as abstract objects — where an abstract object is an object that does not exist in space or time and which is therefore entirely non-physical and non-mental. Platonism in this sense is a **contemporary view**.

## Did Plato discover Platonic Solids?

**These solids were introduced by Plato in his work Timaeus (ca.** **350 BCE)**, in which all then known forms of matter—earth, air, fire, water, and ether—are described as being composed of five elemental solids: the cube, the octahedron, the tetrahedron, the icosahedron, and the dodecahedron.

## What did Plato believe the Platonic Solids represent?

The ancient Greek philosopher Plato c. 360 B.C. theorized that the classical elements of the world were made of these regular solids. The five Platonic Solids were thought to represent **the five basic elements: earth, air, fire, water, and the universe**.

## What did Plato say about mathematics?

Plato believes that **the truths of mathematics are absolute, necessary truths**. He believes that, in studying them, we shall be in a better position to know the absolute, necessary truths about what is good and right, and thus be in a better position to become good ourselves.

## Where does Plato talk about math?

But why did Plato stress on the study of mathematics. One can find the answer in **the seventh book of his masterpiece, The Republic**, where he stated some of his views on the importance of mathematics. To Plato, the idea of good is the ultimate objective of philosophy.

## Is maths a human construct?

2) **Math is a human construct**.

The only reason mathematics is admirably suited describing the physical world is that we invented it to do just that. It is a product of the human mind and we make mathematics up as we go along to suit our purposes.

## Is there a sixth Platonic solid?

Meet the **Hyper-Diamond**! It’s the sixth Platonic Solid and it only works in the fourth dimension.

## Who believed that the four elements can be described geometrically?

**Euclid** (c. 325-265 BC), of Alexandria, probably a student at the Academy founded by Plato, wrote a treatise in 13 books (chapters), titled The Elements of Geometry, in which he presented geometry in an ideal axiomatic form, which came to be known as Euclidean geometry.

## What four solids did Plato believed made up the four elements?

The ancients believed that the world was made up of four basic “elements”: **earth, water, air, and fire**. Around 350 BC, the ancient Greek philosopher Plato, in his book Timaeus, theorized that these four elements were all aggregates of tiny solids (in modern parlance, atoms).

## Are all prisms Platonic solids?

**No, not all prisms are platonic solids, but some are**. By definition, a prism is a solid object that has flat faces and identical faces on each end.

## Is sphere a Platonic solid?

Well, **a Platonic solid looks a lot like a sphere in ordinary 3-dimensional space, with its surface chopped up into polygons**. So, a 4d regular polytope looks a lot like a sphere in 4-dimensional space with its surface chopped up into polyhedra!

## What is the strongest Platonic solid?

The project also ended with a conclusion that the **cube, tetrahedron, and octahedron** are the strongest Platonic solids.

## Why can’t there be a sixth Platonic solid?

In a nutshell: it is impossible to have more than 5 platonic solids, because **any other possibility violates simple rules about the number of edges, corners and faces we can have together**.

## Are there only 5 regular polyhedra?

Platonic solid, any of the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the **tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron**.

## Is the earth a dodecahedron?

The dodecahedron corresponds to the UNIVERSE because the zodiac has 12 signs (the constellations of stars that the sun passes through in the course of one year) corresponding to the 12 faces of the dodecahedron. So thus meaning that **the earth is a dodecahedron**.

## What did Plato say about the dodecahedron?

The fifth, the dodecahedron, has pentagonal faces. Plato believed that the first four corresponded to the elements of which the Greeks thought the material world was composed: fire, air, water and earth. The dodecahedron, however, **corresponded to quintessence, the element of the heavens**.

## Is a cube a Hexahedron?

A hexahedron (plural: hexahedra) is any polyhedron with six faces. **A cube, for example, is a regular hexahedron with all its faces square, and three squares around each vertex**. There are seven topologically distinct convex hexahedra, one of which exists in two mirror image forms.
