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.
However, in some extreme events, may be measurable while other extreme events can probe an additional parameter: the size of the Einstein ring in the plane of the observer, known as the Projected Einstein radius: ~. This parameter describes how the event will appear to be different from two observers at different locations, such as a satellite ...
Baby Einstein, stylized as baby einstein, is an American franchise and line of multimedia products, including home video programs, CDs, books, flash cards, toys, and baby gear that specialize in interactive activities for infants and toddlers under three years old, created by Julie Aigner-Clark. The franchise is produced by The Baby Einstein ...
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 aqua circle is the light source as it would be seen if there were no lens, while white spots are the multiple images of the source (see Einstein ring). A gravitational lens is matter, such as a cluster of galaxies or a point particle , that bends light from a distant source as it travels toward an observer.
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.
Dog, Cat, Bear, Pig and Elephant are the Curious Buddies, a group of five animal puppets who have fun exploring the world around them. Every episode features real-life kids helping the puppets and original music clips. According to a New York Post article, Curious Buddies was designed as an alternative to the successful Baby Einstein series.
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
