An Einstein Ring is a special case of gravitational lensing, caused by the exact alignment of the source, lens, and observer. This results in symmetry around the lens, causing a ring-like structure. [2] The geometry of a complete Einstein ring, as caused by a gravitational lens. The size of an Einstein ring is given by the Einstein radius.
Little Einsteins is an American animated children's television series developed by Douglas Wood and based on the Baby Einstein line of videos. Produced by The Baby Einstein Company (at the time owned by Disney) and animated by Curious Pictures, it marked the Baby Einstein Company's first project for preschoolers. [1] The show centers around of ...
The Einstein radius, also called the Einstein angle, is the angular radius of the Einstein ring in the event of perfect alignment. It depends on the lens mass M, the distance of the lens d L, and the distance of the source d S:
Curious Buddies is a series of direct-to-video specials narrated by Cathy Richardson. [1] It was produced by Spiffy Pictures for Nick Jr. The series was released across seven videos from August 31, 2004, to April 12, 2005. The series is aimed at babies and toddlers. It was made to compete with the Baby Einstein line.
A new photograph from the Hubble Space Telescope shows a stunning “Einstein Ring” billions of light-years from Earth — a phenomenon named after Albert Einstein.
In 2010, a series of Baby Einstein box sets called Discovery Kits were made with Julie Aigner-Clark as the director. Later in 2012, they were released as original videos. The nine Discovery Kits came with a DVD, CD with selections of music heard in the video, and a book and discovery cards for small children.
For a source right behind the lens, θ S = 0, the lens equation for a point mass gives a characteristic value for θ 1 that is called the Einstein angle, denoted θ E. When θ E is expressed in radians, and the lensing source is sufficiently far away, the Einstein Radius , denoted R E , is given by
The children's television show Little Einsteins and the educational toys and videos of the Baby Einstein series both use Einstein's name, though not his image.. Iranian cartoonist and humorist Javad Alizadeh publishes a column titled "4D Humor" in his Persian monthly Humor & Caricature, which features cartoons, caricatures and stories on Einstein-related topics.
