Jun 19, 2024 · Shaula, Lambda Scorpii (λ Sco), is a triple star system located at a distance of about 570 light years from Earth in the direction of the constellation Scorpius. With an apparent magnitude of 1.62, it is the second brightest star in Scorpius, fainter only than the red supergiant Antares. It marks the Scorpion’s stinger with its fainter neighbour Lesath.
4 days ago · Sirius is the brightest star in the night sky. Its name is derived from the Greek word Σείριος (Latin script: Seirios ), meaning lit. 'glowing' or 'scorching'. The star is designated α Canis Majoris, Latinized to Alpha Canis Majoris, and abbreviated α CMa or Alpha CMa. With a visual apparent magnitude of −1.46, Sirius is almost twice ...
1 day ago · The quaternion is called the vector part (sometimes imaginary part) of q, and a is the scalar part (sometimes real part) of q. A quaternion that equals its real part (that is, its vector part is zero) is called a scalar or real quaternion, and is identified with the corresponding real number.
Jun 27, 2024 · Because acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is also a vector quantity. Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval. Instantaneous acceleration (at a precise moment and location) is given by the limit of the ratio of the change in velocity during a given time interval to the time ...
1 day ago · The definitions of eigenvalue and eigenvectors of a linear transformation T remains valid even if the underlying vector space is an infinite-dimensional Hilbert or Banach space. A widely used class of linear transformations acting on infinite-dimensional spaces are the differential operators on function spaces.
If you use the 1997 parallax value, Dschubba' absolute magnitude is -3.16. If you use the 2007 parallax value, Dschubba' absolute magnitude is -3.60. Absolute Magnitude is the star's apparent magnitude from 10 parsecs or 32.6 light years. The magnitude assumes nothing is between the object and the viewer, such as dust clouds.
3 days ago · Entropy is a scientific concept that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory.
