We describe what may beall the best packings of nonoverlapping equal spheres in dimensionsn ≤10, where “best” means both having the highest density and not permitting any local improvement. For example, the best five-dimensional sphere packings are parametrized by the 4-colorings of the one-...
Empedocles,felt that Parmenides’s theory could not explain the variety of differentthings we can see in the world, nor why the worldappears to be constantlychanging. Instead, he suggested that rather than one fundamental substance,there are four, which he called elements: fire, water, earth, ...

As the creatures evolved, this patch started to curve inward to better focus light. 随着生物的进化,这个光斑开始向内弯曲,以便更好地聚焦光线。 And now, a whole bunch of evolution later, what we've arrived at are two twinkling spheres that are capable of seeing about a million colours. 经过...
There are three types of surface area in solids: lateral surface area (LSA), curved surface area (CSA), and total surface area (TSA). Curved Surface Area of SphereThe curved surface area is the sum of areas of all the curved regions of the solid.The curved surface area of a sphere ...

The volumes of two spheres are in a ratio of 1:8. What is the ratio of their radii? A sphere of radius r has surface area A = 4\pi r^2 and volume V = \frac{4}{3}\pi r^3. If the radius of sphere 2 is double the radius of sphere 1, w...
However, electric vehicles require a host of innovations in other spheres, such as high-capacity rechargeable batteries and charging infrastructure. In addition, the benefits of electric vehicles are limited by the fact that many power grids still rely on fossil fuels. ...
