1 day ago · The value of the Hubble constant, H 0, tells the rate at which the universe is expanding. In 1929, Edwin Hubble determined for the first time this constant to be 500 km/s per million parsecs. Since then, Hubble constant has been actively measured using various methods.
5 days ago · E = mc2, equation in German-born physicist Albert Einstein ’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other. In the equation, the increased relativistic mass (m) of a body times the speed of light squared (c2) is equal to the kinetic energy (E) of that body.
1 day ago · This is different from the polynomial obtained earlier, but only by a constant factor. The constant factor is used to set the normailization for the Legendre polynomials.
2 days ago · What Is Big O Notation? Big O notation is a mathematical notation used in computer science to describe the upper bound or worst-case scenario of an algorithm's runtime complexity in terms of the input size. It provides a standardized and concise way to express how an algorithm's performance scales as the input size grows.

1 day ago · In physics, engineering and mathematics, the Fourier transform (FT) is an integral transform that takes a function as input and outputs another function that describes the extent to which various frequencies are present in the original function. The output of the transform is a complex -valued function of frequency.
1 day ago · If the mean =, the first factor is 1, and the Fourier transform is, apart from a constant factor, a normal density on the frequency domain, with mean 0 and variance /. In particular, the standard normal distribution is an eigenfunction of the Fourier transform.
