3 hours ago · For example, for Newton's method as applied to a function f to oscillate between 0 and 1, it is only necessary that the tangent line to f at 0 intersects the x-axis at 1 and that the tangent line to f at 1 intersects the x-axis at 0. This is the case, for example, if f(x) = x 3 − 2x + 2.
3 hours ago · History Early history. The hypothesis of dark matter has an elaborate history. In the appendices of the book Baltimore lectures on molecular dynamics and the wave theory of light where the main text was based on a series of lectures given in 1884, Lord Kelvin discussed the potential number of stars around the Sun from the observed velocity dispersion of the stars near the Sun, assuming that ...
3 hours ago · Ellipses are common in physics, astronomy and engineering. For example, the orbit of each planet in the Solar System is approximately an ellipse with the Sun at one focus point (more precisely, the focus is the barycenter of the Sun–planet pair). The same is true for moons orbiting planets and all other systems of two astronomical bodies.

1 day ago · ℓ ∞ , {\displaystyle \ell ^ {\infty },} the space of bounded sequences. The space of sequences has a natural vector space structure by applying addition and scalar multiplication coordinate by coordinate. Explicitly, the vector sum and the scalar action for infinite sequences of real (or complex) numbers are given by: Define the -norm:
1 day ago · Robotics is the interdisciplinary study and practice of the design, construction, operation, and use of robots. [1] Within mechanical engineering, robotics is the design and construction of the physical structures of robots, while in computer science, robotics focuses on robotic automation algorithms. Other disciplines contributing to robotics ...
3 hours ago · Overview and definition. Modernism was a cultural movement that impacted the arts as well as the broader zeitgeist. It is commonly described as a system of thought and behavior marked by self-consciousness or self-reference, prevalent within the avant-garde of various arts and disciplines. [13]
