Päiksevarjuki peamine eesmärk on hoida objektiivi esiläätsest eemal pildikvaliteeti vähendav külgvalgus. Samuti kaitseb varjuk esiläätse mingil määral ka kahjustuste eest (näiteks kukkumisel või löögi korral)., Sobivus: Canon EF 70-200mm F2.8L USM.
An acclaimed textile designer, author, artist, and photographer, Alice Starmore is a native of Scotland's Isle of Lewis. Starmore has taught and lectured extensively throughout Britain, Europe, and the United States. She has written 16 books and countless magazine articles, and her classic Book of Fair Isle Knitting is the work that introduced Americans to the popular traditional technique. 4 Questions with Alice Starmore: An Exclusive Dover Interview Alice Starmore has a fascinating tale to tell. We spoke to the author of the #1 crafts bestseller Alice Starmore's Book of Fair Isle Knitting about her knitting background, professional start, and more. Clearly, knitting is a deeply ingrained facet of the culture of Scotland's Outer Hebrides. Did your mother teach you to knit? My mother taught me to knit when I was very young. She was a dressmaker as well as a knitter and our house was a place of constant creativity. I was also born at a time when most women knitted as a matter of course, and I had three aunts who had been fisher girls in their youth and were experts at making traditional fishermen's gansies. I understand that your first language is Gaelic — do you still speak it?Yes I still speak Gaelic. The Isle of Lewis, where I live, is in the Outer Hebrides — the heartland of Gaelic and the only place where you will hear the language in everyday use.How did you get your start professionally?I designed a small collection of knitwear in 1975 and successfully sold it in London boutiques. It was featured in a national newspaper and from that small beginning my knitting career evolved in ways that were quite unimaginable to me when I began. Your books are known and loved around the world, and you've adapted design elements from the textile arts of many countries into your repertoire. Are you still discovering "new" aspects of knitting and fabric arts from other cultures?I am interested in everything. I find inspiration in all aspects of the world around me. There is enough inspiration in the natural world on my doorstep to last many lifetimes. I am also inspired by art, culture, history, science and music. My own culture features widely in my design work but I have always been interested in other cultures and in other places. My main problem is that I cannot possibly live long enough to produce work from the amount of ideas that come into my head.
As in its parent game Kakerlakenpoker, Kakerlakenpoker Royal has nothing to do with poker except that the game is all about bluffing, but with cards showing cockroaches, rats and stink bugs instead of queens, 10s and aces. To set up the game, shuffle the deck and deal the cards out to players. On a turn, a player takes one card from his hand, lays it face down on the table, slides it to a player of his choice, and declares a type of critter, e.g., "Stink bug". The player receiving the card either: Accepts the card, says either "true" or "false", then reveals the card. If this player is wrong in her claim, she keeps the card on the table in front of her face up; if she is right, the player who gave her the card places it face up before him. Passes the card to another player, peeking at it first, then keeping it face-down and either saying the original type of critter or saying a new type. This new player again has the choice of accepting the card or passing it, unless the card has already been seen by all other players in which case the player must accept it and make a true/false claim. The game ends when a player has no cards to pass on his turn or when a player has four cards of the same critter on the table in front of him. In either case, this player loses and everyone else wins. To this, Kakerlakenpoker Royal adds new rules and new nasty "royal" critters to create more options for players during the game.

Charles Frederick Mosteller ( 1916–2006) was one of the eminent statisticians of the 20th century. He was the founding chairman of Harvard's Statistics department. Dr. Mosteller wrote more than 50 books and more than 350 papers, with over 200 coauthors. Frederick Mosteller: Harvard Man Frederick Mosteller (1916–2006) founded Harvard University's Department of Statistics and served as its first chairman from 1957 until 1969 and again for several years in the 1970s. He was the author or co-author of more than 350 scholarly papers and more than 50 books, including one of the most popular books in his field, first published in 1965 and reprinted by Dover in 1987, Fifty Challenging Problems in Probability with Solutions. Mosteller's work was wide-ranging: He used statistical analysis of written works to prove that James Madison was the author of several of the Federalist papers whose authorship was in dispute. With then–Harvard professor and later Senator Daniel P. Moynihan, he studied what would be the most effective way of helping students from impoverished families do better in school — their answer: to improve income levels rather than to simply spend on schools. Later, his analysis of the importance to learning of smaller class sizes buttressed the Clinton Administration's initiative to hire 100,000 teachers. And, as far back as the 1940s, Mosteller composed an early statistical analysis of baseball: After his team, the Boston Red Sox, lost the 1946 World Series, he demonstrated that luck plays an enhanced role in a short series, even for a strong team. In the Author's Own Words:"Though we often hear that data can speak for themselves, their voices can be soft and sly." — Frederick Mosteller

By the author of The Handmaid's Tale and The Testaments A leathery bog-man transforms an old love affair; a sweet, gruesome gift is sent by the wife of an ex-lover; landscape paintings are haunted by the ghost of a young girl. This dazzling collection of ten short stories takes us into familiar Atwood territory to reveal the logic of irrational behaviour and the many textures lying beneath ordinary life. 'Atwood is a writer of importance, with a deep understanding of human behaviour, a beautiful understated style and, rarest of all, a broad scope' Marilyn French 'Funny, sharp and always incisive' Time Out 'Everything Atwood forms in words has substance and weight' Daily Telegraph 'Margaret Atwood deserves an adjective - Atwoodian - in recognition of her virtuoso wit and unmistakable style' Chicago Tribune
