Is a donut the same as a coffee mug?
In the metaphor, the mug and the donut are one and the same. If they were made out of rubber, one could be twisted and stretched into the shape of the other without changing its essence. The two are considered topologically equivalent as each has a hole—the ear of the mug and the centre of the donut.
Is a coffee mug equivalent by distortion to a doughnut Why or why not?
11 Yes, they are equivalent. The short answer is that they both have a single hole in them. To really show equivalence, it’s necessary to describe the distortion that turns one object into the other.
Is a coffee mug a torus?
A recent Nature article (below) was inspiration for this post. A continuous deformation (a type of homeomorphism) of a mug into a doughnut (torus) and a cow into a sphere. A coffee mug morphing into a torus, a popular example in topology.
How would you describe a coffee mug?
A mug is a type of cup typically used for drinking hot drinks, such as coffee, hot chocolate, or tea. Mugs usually have handles and hold a larger amount of fluid than other types of cup. A travel mug is insulated and has a cover with a small sipping opening to prevent spills.
What is topology donut?
In the field of topology, a torus is any topological space that is homeomorphic to a torus. The surface of a coffee cup and a doughnut are both topological tori with genus one.
Are a sphere and a torus equivalent by distortion?
The sphere has the property that every loop on it can be “shrunk to a point”. The torus does not have this property. It is a theorem that every connected, bounded surface (2-manifold) with no boundary, such that every loop can be shrunk to a point, is equivalent by distortion to the sphere.
What is a donut in topology?
In geometry, a torus (plural tori, colloquially donut) is a surface of revolution generated by revolving a circle in three-dimensional space about an axis that is coplanar with the circle.
What is torus topology?
Abstract: Torus networks are an attractive topology in supercomputing, balancing the tradeoff between network diameter and hardware costs. The nodes in a torus network are connected in a k-dimensional wrap-around mesh where each node has 2k neighbors.
What is the difference between a cup and a mug?
A cup is a small, round container, usually with a handle, from which you drink hot drinks such as tea and coffee. A mug is a large deep cup with straight sides and a handle, used for hot drinks. You don’t rest a mug on a saucer. He spooned instant coffee into two of the mugs.
Is mug a verb or noun?
mug. verb (1) mugged; mugging. Definition of mug (Entry 2 of 3) intransitive verb.
Are humans technically donuts?
Topologically speaking, the human body and a ring doughnut have exactly the same shape. The inside of your GI tract is therefore outside your body.
Is a donut shaped planet possible?
A donut planet, also known as a toroid planet, is a theoretical type of planet that resembles a donut, rather than a typical sphere. While a donut planet is extremely unlikely to naturally exist anywhere in the universe, it is actually possible for such a planet to exist.
