Pearl breaks the big we-need-a-sandcastle problem into smaller steps, then uses conditionals, loops, and other basic coding concepts to tell Pascal exactly what to do. But building a sandcastle isn’t as easy as it sounds when surfboards, mischievous dogs, and coding mishaps get in the way! Just when it looks like the sandcastle might never work, Pearl uses her coding skills to save the day and create something even better: a gorgeous sandcastle kingdom!

    Their creations are some of the most enduring (the windshield wiper) and best loved (the chocolate chip cookie). What inspired these women, and just how did they turn their ideas into realities?Features women inventors Ruth Wakefield, Mary Anderson, Stephanie Kwolek, Bette Nesmith Graham, Patsy O. Sherman, Ann Moore, Grace Murray Hopper, Margaret E. Knight, Jeanne Lee Crews, and Valerie L. Thomas, as well as young inventors ten-year-old Becky Schroeder and eleven-year-old Alexia Abernathy. Illustrated in vibrant collage by Caldecott Honor artist Melissa Sweet.

    Like her mother, she had a passion for science, math, and machines. It was a very good combination. Ada hoped that one day she could do something important with her creative and nimble mind.A hundred years before the dawn of the digital age, Ada Lovelace envisioned the computer-driven world we know today. And in demonstrating how the machine would be coded, she wrote the first computer program. She would go down in history as Ada Lovelace, the first computer programmer.Diane Stanley’s lyrical writing and Jessie Hartland’s vibrant illustrations capture the spirit of Ada Lovelace and bring her fascinating story vividly to life.

    If you had a beaver's, you'd have orange teeth! And if you had a naked mole rat's set of teeth, you could move each one separately, like chopsticks! The animal kingdom has lots of cool teeth, but yours are pretty awesome, too!

    

    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.

    As we dream with him, we are taken further and further into mathematical theory, where ideas eventually take flight, until everyone--from those who fumble over fractions to those who solve complex equations in their heads--winds up marveling at what numbers can do.Hans Magnus Enzensberger is a true polymath, the kind of superb intellectual who loves thinking and marshals all of his charm and wit to share his passions with the world. In The Number Devil, he brings together the surreal logic of Alice in Wonderland and the existential geometry of Flatland with the kind of math everyone would love, if only they had a number devil to teach them.

    Who was Grace Hopper? A software tester, workplace jester, cherished mentor, ace inventor, avid reader, naval leader—AND rule breaker, chance taker, and troublemaker. Grace Hopper coined the term “computer bug” and taught computers to “speak English,” and throughout her life succeeded in doing what no one had ever done before. Delighting in difficult ideas and in defying expectations, the insatiably curious Hopper truly is “Amazing Grace” . . . and a role model for science- and math-minded girls and boys.

    She is small. Very small. In fact so small that you'd need to look through a microscope to see her. Or you can simply open this book and take Min on an adventure to amazing places she's never seen before—like the icy glaciers of your tooth or the twisted, tangled jungle that is your shirt. The perfect book for anyone who wants to take a closer look at the world.

    It's been around for centuries; from the ancient Greeks to the American Indians, everyone's chewed it. But the best kind of gum; bubble gum! wasn't invented until 1928, when an enterprising young accountant at Fleer Gum and Candy used his spare time to experiment with different recipes. Bubble-blowing kids everywhere will be delighted with Megan McCarthy's entertaining pictures and engaging fun facts as they learn the history behind the pink perfection of Dubble Bubble.

    Her parents separated when she was young, and her mother insisted on a logic-focused education, rejecting Byron’s “mad” love of poetry. But Ada remained fascinated with her father and considered mathematics “poetical science.” Via her friendship with inventor Charles Babbage, she became involved in “programming” his Analytical Engine, a precursor to the computer, thus becoming the world’s first computer programmer. This picture book biography of Ada Lovelace is a portrait of a woman who saw the potential for numbers to make art.

    A tiny leak could shoot pressurized water straight through the men like bullets! A single spark could cause their oxygen tanks to explode! No one had ever dived lower than a few hundred feet...and come back. But Otis and Will were determined to become the first people to see what the deep ocean looks like.This suspenseful story from acclaimed author Barb Rosenstock with mesmerizing watercolors by award-winning artist Katherine Roy will put you right in the middle of the spine-tingling, record-setting journey down, down into the deep.
