And, it's true, many of them do. But Paul Erdos never followed the usual path. At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.

    Inspired by an Ig Nobel Prize–winning investigation of how cats behave like liquids, it introduces some of the physical properties of liquids—they adapt to fit a container, they flow like fluids—and is just pure fun. Like its inspiration, it makes you laugh, then think. Back matter includes a brief introduction to the different physical states: solid, liquid, gas.

    But what if we took these big, hard-to-imagine objects and events and compared them to things we can see, feel and touch? Instantly, we'd see our world in a whole new way." So begins this endlessly intriguing guide to better understanding all those really big ideas and numbers children come across on a regular basis. Author David J. Smith has found clever devices to scale down everything from time lines (the history of Earth compressed into one year), to quantities (all the wealth in the world divided into one hundred coins), to size differences (the planets shown as different types of balls). Accompanying each description is a kid-friendly drawing by illustrator Steve Adams that visually reinforces the concept. By simply reducing everything to human scale, Smith has made the incomprehensible easier to grasp, and therefore more meaningful. The children who just love these kinds of fact-filled, knock-your-socks-off books will want to read this one from cover to cover. It will find the most use, however, as an excellent classroom reference that can be reached for again and again when studying scale and measurement in math, and also for any number of applications in social studies, science and language arts. For those who want to delve a little deeper, Smith has included six suggestions for classroom projects. There is also a full page of resource information at the back of the book.

    In fact, five of them could fit into the period at the end of this sentence.On a clear, warm Sunday, April 14, 1935, a wild wind whipped up millions upon millions of these specks of dust to form a duster—a savage storm—on America's high southern plains.The sky turned black, sand-filled winds scoured the paint off houses and cars, trains derailed, and electricity coursed through the air.

    At the Cheetah Conservation Fund's (CCF) African headquarters in Namibia, Laurie Marker and her team save these stunning, swift, and slender creatures from extinction. Since the organization's start in 1990, they've rescued more than 900 cheetahs, most of whom have been returned to the wild.     But this arduous challenge continues. For most African livestock farmers, cheetahs are the last thing they want to see on their properties. In the 1980s, as many as 19 cheetahs per farmer died each year. Cheetahs were considered vermin--but, in learning more about this magnificent species, we know this is far from true.     Today, CCF acts as a liaison between the farmers and the cheetahs, in order to promote cohabitation in an ecosystem that cannot thrive without the existence of the precious and predatory cheetah. On a wild ride through the African wilderness--sometimes sniffing out scents left in the dirt--Sy Montgomery and Nic Bishop join CCF in studying the cheetah's ecological, genetic, and behavioral patterns in order to chase down the fastest animal on land and save the species--before it is too late.

    On a cold January day in 2017, nearly two months before her due date, Nile hippopotamus Bibi gave her keepers at the Cincinnati Zoo & Botanical Garden a big (little) surprise - a tiny newborn hippo, no bigger than a football.  The first premature hippo born and raised in captivity, baby Fiona was an underdog from the start:  she couldn't nurse, she couldn't stay hydrated, and she wasn't thriving. But the staff at the zoo knew they could save her.  It would take creative thinking and teamwork. They would have to study the makeup of hippo milk for the first time ever and reach out to medical colleagues, including a team at the local Children's Hospital with superior vein-finding skills,  to ensure that Fiona would begin to gain weight and become healthy. When Fiona began to thrive, her star began to rise, and soon she became an internet sensation, her picture and videos garnering thousands and thousands of likes and fans on Instagram and Facebook.  Now a Fiona appearance at the Zoo mimics a Beatles concert.  What made this little, now big, hippo such a big hit with people all over the world?  And what's in store for her and her family in the future?
