These first Heisler–Gröber charts were based upon the first term of the exact Fourier series solution for an infinite plane wall: (,) = = [ + ], [1]where T i is the initial uniform temperature of the slab, T ∞ is the constant environmental temperature imposed at the boundary, x is the location in the plane wall, λ is the root of λ * tan λ = Bi, and α is thermal diffusivity.
Below the complex spherical harmonics are represented on 2D plots with the azimuthal angle, , on the horizontal axis and the polar angle, , on the vertical axis.The saturation of the color at any point represents the magnitude of the spherical harmonic and the hue represents the phase.
360-degree videos, also known as surround video, [1] or immersive videos [2] or spherical videos, [3] are video recordings where a view in every direction is recorded at the same time, shot using an omnidirectional camera or a collection of cameras.
Grisly video has emerged of a blood-soaked woman after she was allegedly caught killing and eating a cat in Ohio — but she’s neither a Haitian migrant nor anywhere near Springfield.
In the theory of Lorentzian manifolds, spherically symmetric spacetimes admit a family of nested round spheres.In such a spacetime, a particularly important kind of coordinate chart is the Schwarzschild chart, a kind of polar spherical coordinate chart on a static and spherically symmetric spacetime, which is adapted to these nested round spheres.

The brain of the domesticated cat is about five centimetres (2.0 in) long and weighs 25–30 g (0.88–1.06 oz). [1] [2] If a typical cat is taken to be 60 cm (24 in) long with a weight of 3.3 kg (7.3 lb), then the brain would be at 0.91% [3] of its total body mass, compared to 2.33% [3] of total body mass in the average human.
The defining characteristic of an isotropic chart is that its radial coordinate (which is different from the radial coordinate of a Schwarzschild chart) is defined so that light cones appear round. This means that (except in the trivial case of a locally flat manifold), the angular isotropic coordinates do not faithfully represent distances ...
