The raucously witty Yiddish classic about a Jewish Paradise afflicted by very human temptations and pains, in a new translation On being expelled from Paradise, young Samuel Abba pulls a crafty trick, managing to arrive on earth with his memory intact. He quickly begins regaling the humans around him with mischievous stories of a Paradise far from their expectations: a world of drunken angels, lewd patriarchs and the same divisions and temptations that shape the human world. The Book of Paradise is a comic masterpiece, and the only novel by one of the great Yiddish writers. Written in the midst of rising anti-Semitism in 1930s Europe, its raucous blend of sacred and profane is a slyly profound reflection of the author's turbulent times.

A new experimental method – the "Stiffnessometer", is developed to measure elementary properties of a superconductor, including the superconducting stiffness and the critical current. This technique has many advantages over existing methods, such as: the ability to measure these properties while minimally disturbing the system; the ability to measure large penetration depths (comparable to sample size), as necessary when approaching the critical temperature; and the ability to measure critical currents without attaching contacts and heating the sample. The power of this method is demonstrated in a study of the penetration depth of LSCO, where striking evidence is found for two separate critical temperatures for the in-plane and out-of-plane directions. The results in the thesis are novel, important and currently have no theoretical explanation. The stiffnessometer in a tool with great potential to explore new grounds in condensed matter physics.

As the characters appear in the story, it signals children to practice those poses.The book includes about 50 yoga exercises that make up a program especially designed for children, with a focus on proper breathing.In addition, the stories in the book highlight important values such as nonviolence, respect for others, and a healthy lifestyle. The stories will engage and expand your child's imagination, while the yoga poses will help develop their physical, neural, and mental abilities--such as coordination and posture--while improving their self-confidence.The book is designed for children ages four to twelve. Parents can read the stories to younger children, using the pictures and instructions that accompany each story to guide children through the poses. Older children who know how to read can learn independently and practice without any help.With Yoga Story, you are giving your child an important tool for coping with daily life--and offering them lifelong benefits. Inspired by the book's engaging stories and characters, your child will easily learn the illustrated yoga poses, and experience the vital connection between body and mind Itzik Oron is a veteran yoga teacher and expert in children's learning processes. He is certified by Israel's Wingate Institute--one of the world's most advanced sports training facilities--where he studied yoga and yoga for children. Oron wrote this book after teaching thousands of yoga classes for children in recent years. The book draws on his in-depth knowledge and true understanding of young children's abilities, and features the great expertise gained from his many years of experience with yoga's positive impact on children.More on the importance of yoga in children: ① Kids who practice yoga are able to control their emotions better and can calm themselves when stressed. Studies show that these children also tend to opt for a healthier diet, and that they are more engaged in sports activities than children who do not practice yoga.② Yoga has a profound effect children's health. Children today suffer from various diseases and disorders, including the affluent diseases of the West--like heart problems, diabetes, and obesity at an early age. Proper breathing practice, non-competitive movement, and deep relaxation have been proven to be an effective means of healing.③ Once yoga is instilled in children, it becomes part of their lifestyle, their behavior, and their language. Children love to practice yoga, and they love the feeling it gives them.

In Going Up and Going Down Yitzhak Peleg argues that the story of Jacob’s dream (Genesis 28.10-22), functions as a mise en abyme (‘as a figure, trope or structure that somehow reflects in compact form, in miniature, the larger structure in which it appears’, Greenstein). Close examination reveals that focusing on the vision of Jacob’s dream and understanding it as a symbolic dream facilitates an explanation of the dream and its meaning. Scholars have historically classified the dream as theophany, the purpose of which is to explain how Beth-El became a sacred place, and as such the vision in Jacob’s dream is generally accepted as merely ornamental, or even lacking a message in itself. Whilst Peleg does not contradict or seek to go against identification of the dream as theophany, he sees a more nuanced purpose behind its presentation. Peleg’s proposal is that the description of the vision, and especially that of the movement of the angels, is not embellishment, supplementation or scenic background, of God’s message, but that it directly symbolizes the path taken by the Patriarchs to and from the Promised Land. Furthermore, the narrative context and visual description in the dream in which ‘Angels of God were going up and down it’ appears when Jacob is on his way to Harran, that is to say, when he is about to leave Israel.
