1 dzień temu · Definition. Consider a matrix A and a nonzero vector .If applying A to (denoted by ) simply scales by a factor of λ, where λ is a scalar, then is an eigenvector of A, and λ is the corresponding eigenvalue. This relationship can be expressed as: =. There is a direct correspondence between n-by-n square matrices and linear transformations from an n-dimensional vector space into itself, given ...
1 dzień temu · A neutrino (⫽ nj uː ˈ t r iː n oʊ ⫽ new-TREE-noh; denoted by the Greek letter ν) is a fermion (an elementary particle with spin of 1 / 2) that interacts only via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small that it was long thought to be zero.The rest mass of the neutrino is much smaller than that ...
