Professor Einstein is marketed as an educational tool to teach science, primarily to children ages 8–13. [35] The robot can speak about science, tell jokes, and connect to Wifi to check the weather or access information on the internet. It has a corresponding app called the Stein-O-Matic that offers games, videos, and lessons. [36]
The Atlanta Business Chronicle named Kids II one of the best places to work in Atlanta in 2013. [16] [17] In October 2013, Kids 2 acquired Baby Einstein, formerly owned by The Walt Disney Company. [18] Baby Einstein products use real world objects, music, art, animals and nature with the intention to introduce infants to the world around them ...
In mathematics, especially the usage of linear algebra in mathematical physics and differential geometry, Einstein notation (also known as the Einstein summation convention or Einstein summation notation) is a notational convention that implies summation over a set of indexed terms in a formula, thus achieving brevity.
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 ...
Albert Einstein (/ ˈ aɪ n s t aɪ n /, EYEN-styne; [4] German: [ˈalbɛʁt ˈʔaɪnʃtaɪn] ⓘ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who is best known for developing the theory of relativity. Einstein also made important contributions to quantum mechanics.
The two-postulate basis for special relativity is the one historically used by Einstein, and it is sometimes the starting point today. As Einstein himself later acknowledged, the derivation of the Lorentz transformation tacitly makes use of some additional assumptions, including spatial homogeneity, isotropy, and memorylessness. [3]
Albert Einstein, physicist, 1879-1955, Graphic: Heikenwaelder Hugo,1999 Special relativity is a theory of the structure of spacetime . It was introduced in Einstein's 1905 paper " On the Electrodynamics of Moving Bodies " (for the contributions of many other physicists and mathematicians, see History of special relativity ).
This idea was introduced in Einstein's 1907 article "Principle of Relativity and Gravitation" and later developed in 1911. [32] Support for this principle is found in the Eötvös experiment , which determines whether the ratio of inertial to gravitational mass is the same for all bodies, regardless of size or composition.
