Vor einem Tag · A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. [2] Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Vor 40 Minuten · Abstract. A common approach to investigating a random set or a process of convex objects is to observe it in an observation window (often convex), to draw some conclusions, and then to increase the window. An example is the determination of a functional density for a stationary particle process by means of a limit relation.
Vor 40 Minuten · The analysis of relative space was also given great prominence by Albert Einstein, who extended Poincaré’s analysis by showing mathematically that the experience of time and motion inevitably depended on the viewer’s choice of space-time coordinates. With the special theory of relativity that he articulated in 1905, Einstein showed how time in one moving reference system appeared to slow ...
Vor einem Tag · The Poincaré group is a Lie group consisting of the symmetries of spacetime in special relativity. Point groups describe symmetry in molecular chemistry . The concept of a group arose in the study of polynomial equations , starting with Évariste Galois in the 1830s, who introduced the term group (French: groupe ) for the symmetry group of the roots of an equation, now called a Galois group .
