# How do you define a torus?

## How do you define a torus?

1 : a doughnut-shaped surface generated by a circle rotated about an axis in its plane that does not intersect the circle. 2 : a smooth rounded anatomical protuberance (as a bony ridge on the skull) a supraorbital torus.

## What does a torus look like math?

In Mathematics, a torus is a doughnut-shaped object such as an O ring. It is a surface of an object formed by revolving a circle in three-dimensional space about an axis that lies in the same plane as the circle.

**Is a torus a shape?**

The shape of this ring is called a torus, a donut shape. Nature invented the shape long before our buildings. A torus is the shape of the magnetic field around our bodies, the shape of the magnetic field around Earth. Some physicists think the universe itself is a spinning torus.

**What is a torus 3D shape?**

A torus is a 3D shape formed by a small circle that rotates around a bigger circle. It usually looks like a circular ring, or a donut.

### Is doughnut a torus?

(The bread of the donut is a three-dimensional space called a solid torus.)

### Are human donuts?

And so if you deform the human body and its inner (GI tract) and outer (skin) surfaces into the simplest possible shape, you end up with a doughnut-shaped object, a torus. All the other openings into the body that aren’t part of the GI tract aren’t holes, topologically/mathematically speaking, they’re cavities.

**Is there a cube planet?**

There can never be an cubic planet. As the round objects have more area than square or rectangular. The other thing is in universe all objets gather mass by rolling.

**How many holes does a person have topologically?**

It talks about topology in the beginning, then it starts to answer the question “how many through holes does a human have”. But if you want the straight up answer, a human is topologicaly equivalent to a 7 hole donut.

## How many holes does a human have topologically?

For a normal human male, discounting pores, we have 9 holes.
