What is a torus in physics?
In geometry, a torus (plural tori, colloquially donut or doughnut) is a surface of revolution generated by revolving a circle in three-dimensional space about an axis that is coplanar with the circle.
How is torus created?
A torus is generated by sweeping a circle around an axis in the same plane as the circle. This means that any plane containing the axis inter- sects the torus in two circles.
What does the torus shape look like?
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.
Are humans a torus?
Topologically speaking, a human is a torus. Your digestive system is the hole in the doughnut. Interestingly, this means in a two-dimensional world, an organism couldn’t have a similar structure, since the digestive system would completely separate the animal into two halves.
What is torus in biology?
The disc-shaped central thickening of pit membrane is known as a torus. Its diameter is wider than that of the pit aperture. It is mainly found in gymnosperms. When it is placed at the median position it helps in easy passage of water while it completely restricts the movement of water when placed laterally.
What is the shape of a Taurus?
Taurus, the bull, is marked by a V-shaped pattern of stars that outlines the bull’s face.
What is torus in botany?
noun. (botany) The end of the peduncle or flower stalk to which the floral parts (in the Asteraceae, the florets of a flower head) are attached; see receptacle. noun. (architecture) A large convex molding, semicircular in cross section, located at the base of a classical column. noun.
What is a circle with a hole in the middle called?
In mathematics, a toroid is a surface of revolution with a hole in the middle.
Do pants have 2 holes?
A pair of pants is any surface that is homeomorphic to a sphere with three holes, which formally is the result of removing from the sphere three open disks with pairwise disjoint closures. Thus a pair of pants is a compact surface of genus zero with three boundary components.
Is human a donut?
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.
What is torus and Margo?
The torus regulates the functions of the bordered pit, and the margo is a cell wall-derived porous membrane that supports the torus. The margo is composed of bundles of microfibrils that radiate from the torus. The margo is flexible and can move towards either side of the pit while under stress.
What is pit in cell?
Pits are thin areas on the secondary cell walls of plants. They look like depressions on the walls. Also, they aid in the transport of minerals and water between the cells. Usually, a pit has a complementary depression in its neighbouring cell. These are termed ‘pit pairs’.

Where is Taurus located in the northern hemisphere?
A constellation in the Northern Hemisphere near Orion and Aries. Taurus (the Bull) contains the bright star Aldebaran and the grouping known as the Pleiades. It is the second sign of the zodiac.
