A man had died of bubonic plague, one of the world’s deadliest diseases. But how could that be possible? Bubonic Panic tells the true story of America’s first plague epidemic—the public health doctors who desperately fought to end it, the political leaders who tried to keep it hidden, and the brave scientists who uncovered the plague’s secrets.

    When she finds it, she lays her eggs on the plant, so when each egg hatches, the baby caterpillar can feed on the milkweed leaves. The milkweed plant then provides the perfect protection as the caterpillar turns into one of nature's wonders, a chrysalis, before transforming into an even greater wonder: a monarch butterfly. And once the newborn butterfly soars away, the milkweed seeds fly away on the wind and start this cycle over again. The exacting prose and jewel-toned illustrations echo the harmony of monarch and milkweed in this carefully researched book, explaining one of nature's most spectacular displays in a refreshingly simple manner.

    Using the insights of great mathematicians and endlessly observing the sky, he succeeded in confirming two things that altered human life forever: that there are more galaxies than our own, and that the universe is always expanding. Hubble’s message to us is to find peace in the vastness of the mystery surrounding us, and to be curious. “We do now know why we are born into the world,” he said, “but we can try to find out what sort of world it is.”

    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.

    Some things are facts--like the number of robots in this book. Other things are opinions--like which robot would make the best friend, or which robot dances best. And sometimes to tell the difference between a fact and an opinion, you need to wait to get more information--that's because facts can be proven true or false, and opinions are things you feel and believe--but that you can't prove.
