Elinor and her friends investigate why they’ve never seen a baby butterfly. On an outing to the park, Elinor, Ari and Olive can’t decide whether they should watch butterflies (Ari’s favorite) or caterpillars (Olive’s favorite). This gets Elinor wondering: Why has she never seen a baby butterfly? The friends search high and low in the park - no baby butterflies. But then they spot a cocoon and as they watch, something unusual happens! If they pay close attention, will they solve the mystery of the baby butterflies? (And discover how Olive’s and Ari’s favorite animals are connected?) Sure to transform kids’ inquisitiveness about insects: they’ll never look at caterpillars - or butterflies - the same way again!

Prepare to learn everything we still don’t know about our strange and mysterious universe Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore —there are huge yawning voids in our basic notions of how the world works. PHD Comics creator Jorge Cham and particle physicist Daniel Whiteson have teamed up to explore everything we don't know about the universe: the enormous holes in our knowledge of the cosmos. Armed with their popular infographics, cartoons, and unusually entertaining and lucid explanations of science, they give us the best answers currently available for a lot of questions that are still perplexing scientists, including: * Why does the universe have a speed limit? * Why aren't we all made of antimatter? * What (or who) is attacking Earth with tiny, superfast particles? * What is dark matter, and why does it keep ignoring us? It turns out the universe is full of weird things that don't make any sense. But Cham and Whiteson make a compelling case that the questions we can't answer are as interesting as the ones we can. This fully illustrated introduction to the biggest mysteries in physics also helpfully demystifies many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humor and delight, Cham and Whiteson invite us to see the universe as a possibly boundless expanse of uncharted territory that's still ours to explore.

A rabbit in a picture book is very glad when a reader turns up.

A brand-new early reader graphic novel series based on the acclaimed PBS Kids TV show. Elinor the rabbit is curious about everything. She loves to “follow her curiosity,” make observations and test her ideas as she explores nature’s mysteries. One day, Elinor’s curiosity is piqued when she and her friends Olive (an elephant) and Ari (a bat) are playing hide-and-seek. Though the friends keep choosing perfect hiding spots, the goat twins keep finding them! And quickly! How can they make themselves harder to find? Is the solution hiding in plain sight? Kids will be thrilled to discover how animals use camouflage: it’s been right in front of their noses the whole time!

"Delightful, funny, and yet rigorous and intelligent: only Jorge and Daniel can reach this exquisite balance." —Carlo Rovelli, author of Seven Brief Lessons on Physics and Helgoland You’ve got questions: about space, time, gravity, and the odds of meeting your older self inside a wormhole. All the answers you need are right here. As a species, we may not agree on much, but one thing brings us all together: a need to know. We all wonder, and deep down we all have the same big questions. Why can’t I travel back in time? Where did the universe come from? What’s inside a black hole? Can I rearrange the particles in my cat and turn it into a dog? Researcher-turned-cartoonist Jorge Cham and physics professor Daniel Whiteson are experts at explaining science in ways we can all understand, in their books and on their popular podcast, Daniel and Jorge Explain the Universe. With their signature blend of humor and oh-now-I-get-it clarity, Jorge and Daniel offer short, accessible, and lighthearted answers to some of the most common, most outrageous, and most profound questions about the universe they’ve received. This witty, entertaining, and fully illustrated book is an essential troubleshooting guide for the perplexing aspects of reality, big and small, from the invisible particles that make up your body to the identical version of you currently reading this exact sentence in the corner of some other galaxy. If the universe came with an FAQ, this would be it.
