Long before she became known as the Cactus Queen, Minerva Hamilton Hoyt found solace in the unexpected beauty of the Mojave Desert in California. She loved the jackrabbits and coyotes, the prickly cacti, and especially the weird, spiky Joshua trees. However, in the 1920s, hardly anyone else felt the same way. The desert was being thoughtlessly destroyed by anyone and everyone. Minerva knew she needed to bring attention to the problem. With the help of her gardening club, taxidermists, and friends, she took the desert east and put its plants and animals on display. The displays were a hit, but Minerva needed to do much more: she wanted to have the desert recognized as a national park. Although she met with President Franklin D. Roosevelt and won him over, Minerva still had to persuade politicians, scientists, teachers, and others to support her cause. And, it worked! Minerva's efforts led to what came to be known as Joshua Tree National Park in California, and saved hundreds of thousands of plants and animals. Now, the millions of people who visit each year have learned to love the desert, just as Minerva did.

“Danmark, hvad har jeg dig gjort, at bort du så grumt mig støder? Hvad kan dog gå mere galt?”Efter 20 frugtbare år på øen Hven i Øresund, hvor mange af de observationer, den moderne astronomihviler på, blev nedfældet, forlod Danmarks betydeligste astronom og videnskabsmand, Tycho Brahe, i 1599 sit fædreland for at finde arbejdsro under sydligere himmelstrøg. Men kunne den arrogante og temperamentsfulde danske videnskabsmand igen finde ro til at fortsætte sine banebrydende beregninger af himmelrummet?Anders Worm fortæller den fascinerende historie om en kontroversiel, genial, insisterende og hårdt arbejdende videnskabsmand, fra Uranienborg (også kendt som Uraniborg) på Hven til sit endeligt i Prag.Tycho Brahe leverede et betydeligt bidrag til den internationale astronomi og står i dag som en af Danmarks allerstørste videnskabsfolk. Men hanslivshistorie viser, at resultaterne også kom medpersonlige omkostninger.

This book is for kids who have just started learning multiplication. When memorizing times tables looms ahead, the fear of the math monster creeps in and spoils what should be a lot of fun at school. I bribed my 7-year-old son with some TV time and chocolates to memorize the x3 table, but this only confirmed his belief that math is a scary tsunami of ever growing numbers and formulas that he would rather never encounter. As a kid I struggled with math too. My Dad is a mathematician. He helped to propel me through high school math, but the fear of the math monster chased me constantly. . How to defeat that fear? You have to confront it from the very start, from the times tables and even before, to help our kids feel more in control, to show them that the math monster can purr and lick their hand. So I roped in my Dad, and together we looked at speed math methods and learning shortcuts, and collected a bunch of tricks that - minimize memorization and - maximize the sense of victory over the math monster ...when learning times tables, 2-digit multiplication, fractions, decimals, as well as addition and subtraction of larger numbers. This book covers math curricula found in the 2nd and 3rd grades - from times tables through decimals. In addition to speed math tricks, the book teaches a few classic math magic tricks, like 'reading your mind' to discover the secret number you came up with, or making a (seemingly) complex calculation in an instant. The book is colorful, with funny illustrations and captions to help retain every last drop of the precious kid attention, and to escape that scary math book look - the arctic white pages with mounting numbers - that so terrified me as a kid. It's a 'fun math' book designed to arm our kids with the magic of confidence and a bunch of speed math tricks on their early math journey.

In elementary school, math word problems were the bane of my existence. I could crunch numbers with ease, but word problems were tricky because of the logical sorting you have to do to arrive at an equation: Establishing what's known and what's unknown and the relationship between them was not easy for me. Some word problems tell a story where events are out of order. You have to re-order them first to grasp what was there at the start, what changes, and what is missing. Some word problems use tricks like: A crocodile is 7 feet long, and that's 3 times shorter than a snake! How long is the snake? In 3rd grade, that word 'shorter' tricked me into division instead of multiplication every single time. This reasoning that turns a word problem into an equation was always the hardest part for me...not the calculations, but the logical part. As a grownup, looking back, I could hardly understand why I was so lost around word problems. But then, seeing my 7-year-old son (currently in 3rd grade) lose track now and then while trying to solve them, I realized that it would be helpful for him to start from the very beginning, from the simplest 1st grade word problems, and strengthen his grasp of the logic: What are we looking for? For the whole, or for the missing part? How to find the missing part if you know the whole?... and so on. This book is a 'guided tour' of the major types of elementary school curriculum word problems, from a + b = ? to multiplication and division - covering material typically taught in Grades 1 through 3. By genre, it's not 'fun math.' Rather, it's an entertaining and colorful tutoring aid for kids, aimed at brushing up their understanding of how to solve word problems. The reading level of the book is about 2nd grade - independent reading (or reading with the parent), simple vocabulary, short paragraphs, lots and lots of pictures. I divide word problems into 'houses': Problems of the same type live together. We visit each house, and first solve a couple word problems together, step-by-step. I explain what is special about each word problem type, and warn of any potential tricks. Then I offer 2 or 3 word problems to be solved by the reader. The answers are at the back of the book. To add a bit of challenge, humor and excitement, every few pages I invite the reader to the House of Tricks - inhabited by trick word problems. I also offer a few puzzles, logical brain-teasers, and, finally, we explore why some numbers, such as 3, or 7, or 9 were believed to be magical in the ancient world. One other thing that bothers me about math word problems, is how boring and unimaginative their stories are. It's always some kids selling T-shirts, buying apples, swimming so many laps, or baking cupcakes. To break out of this mundane environment, I replaced all these boring characters with vampires, fairies, princesses, dragons, mummies, serpents, and occasional historical characters, from Cleopatra and Constantine the Great to Queen Elizabeth I. Oh, one more thing! White paper with endless rows of numbers depresses me. Just don't tell my Dad who has co-authored this book with me. He is a mathematician and his idea of a great time is solving higher math equations for fun after dinner. He is OK if a math book looks like the Arctic landscape with a sprinkling of numbers, but I want color, pictures, and humor. So there you have it, The Star of the Seven Seas.

In this book, I respond to the need for explanations of UAPs/UFOs, as presented by the Report from the Office of the Director of National Intelligence. I work within the Framework of the Pentagon's statement that UAPs are real objects with advanced intelligently controlled technologies, which are not ours (US). I present explanations of the Physics of UFOs/UAPs and how they work. I analyze and explain UAPs' flight characteristics. I present explanations for the observables listed by the National Intelligence Director's Report. I address and refute the hypothesis that UAPs are advanced hypersonic drones from Russia or China. I review and address the National Security as well as air safety concerns. I present case evidence and historical data supporting the hypothesis that some UFOs/UAPs are advanced technologies that do not seem to originate from Earth. It is evidence that may be conducive to the discovery, the realization that we are not alone in the Universe. This book is also intended to be used for additional reading in Astronomy and Physics classes.

Ranbir told me about a little game once. He asked me how thick would a block of paper be if you could fold one sheet 50 times. I thought a bit and finally made a "C" with my hand. "I'n'know, this thick?" He laughed and called me a dummy. Try it! he said, but be sure you have a big sheet of paper. Really big. My name is Buck O'Doul. I'm only seven years old. I decided to take up this challenge and fold the state of Nebraska 50 times and see what I came up with.Little did I know what I was getting into -- I was being sucked into the world of higher mathematics, squares and square roots, hooky things, squishy scales and logarithms, and all pretty much just by counting on my fingers!

Many children find it difficult to learn their times tables, but this bright and attractive pull-the-tab book makes it really easy and fun!
