Nucleation and growth is the dominant relaxation mechanism driving first-order phase transitions. In two-dimensional flat systems, nucleation has been applied to a wide range of problems in physics, ...

With 3D printed arms of fixed measurements, the depth reading from a set of digital calipers can be used to calculate the radius of a curve. Specialized tools that focus on one particular job tend to ...

• There are three possibilities for the curvature of the universe: space can be flat, spherical or hyperbolic • The geometry of the universe depends on its curvature and also on its topology, which ...

You would be forgiven for assuming that we understand the proton. It is, after all, the main constituent of matter in the observable universe, the fuel of stellar furnaces. Studies of the proton—its ...

The author establishes a property of supply for a competitive firm: Assuming differentiability of the production frontier, linearly independent price vectors have disjoint image sets under the supply ...

The spine, or backbone, is made up of small bones (vertebrae) stacked -- along with discs -- one on top of another. A healthy spine, when viewed from the side, has gentle curves to it. The curves help ...

The biggest star in the universe (that we know of), UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of ...
