'''[[Chemistry]]''' is the [[science]] of materials. Chemists consider that all of the materials in the world are matter, primarily made up of [[atom]]s. The combination of at least two atoms connected by a chemical bond leads to molecules. [[Ion]]s are derived from atoms or molecules by loss or gain of one or more electrons leading to charged particles. [[Salt]]s are composed of [[ion|cations]] (positively charged ions) and [[ion|anions]] (negatively charged ions), so that the substance or material is neutrally charged (without net charge). Chemists use their view of [[matter]] at the [[atom]]ic to [[molecule|molecular]] level to explain how different materials interact, and how they change under varying conditions. <font size=1>[[Chemistry|['''more...''']]]</font>

[[Image:Augustin-Louis Cauchy 1901.jpg|right|125px|]]'''[[Augustin-Louis Cauchy]]''' (Paris, August 21, 1789 &ndash; Sceaux, May 23, 1857) was one of the most prominent mathematicians of the first half of the nineteenth century. He was the first to give a rigorous basis to the concept of limit. His criterion for the convergence of [[sequence]]s defines sequences that are now known as [[Cauchy sequence]]s. This notion has led to the fundamental mathematical concept of a [[completeness (mathematics)|complete space]]. The [[Cauchy condition]] for the convergence of [[series (mathematics)|series]] can be found in any present-day textbook on calculus. Probably Cauchy is most famous for his singlehanded development of [[complex function theory]], with Cauchy's [[residue theorem]] as the fundamental result.<font size=1>[[Augustin-Louis Cauchy|['''more...''']]]</font>

Featured Article: Paramhansa Yogananda

Paramhansa Yogananda circa 1920.

Paramhansa Yogananda (5 Jan 1893–7 Mar 1952) was one of the first Indian teachers from the Hindu spiritual tradition to reside permanently in the West, and in particular, he was the first to teach yoga to Americans. He emphasized the universality of the great religions, and ceaselessly taught that all religions, especially Hinduism and Christianity, were essentially the same in their essence. The primary message of Yogananda was to practice the scientific technique of kriya yoga to be released from all human suffering.

He emigrated from India to the United States in 1920 and eventually founded the Self-Realization Fellowship there in Los Angeles, California. He published his own life story in a book called Autobiography of a Yogi, first published in 1946. In the book, Yogananda provided some details of his personal life, an introduction to yoga, meditation, and philosophy, and accounts of his world travels and encounters with a wide variety of saints and colorful personalities, including Therese Neumann, Mohandas K. Gandhi, Luther Burbank, and Jagadis C. Bose.

Paramhamsa, also spelled Paramahamsa, is a Sanskrit title used for Hindu spiritual teachers who have become enlightened. The title of Paramhansa originates from the legend of the swan. The swan (hansa) is said to have a mythical ability to sip only the milk from a water-and-milk mixture, separating out the more watery part. The spiritual master is likewise said to be able to live in a world like a supreme (param) swan, and only see the divine, instead of all the evil mixed in there too, which the worldly person sees.

Yogananda is considered by his followers and many religious scholars to be a modern avatar.

In 1946, Yogananda published his Autobiography of a Yogi. It has since been translated into 45 languages, and in 1999 was designated one of the "100 Most Important Spiritual Books of the 20th Century" by a panel of spiritual authors convened by Philip Zaleski and HarperCollins publishers.

Awake: The Life of Yogananda is a 2014 documentary about Paramhansa Yogananda, in English with subtitles in seventeen languages. The documentary includes commentary by George Harrison and Ravi Shankar, among others.[1][2]
