Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked. After Henrietta observed that certain stars had a fixed pattern to their changes, her discovery made it possible for astronomers to measure greater and greater distances—leading to our present understanding of the vast size of the universe.An astronomer of her time called Henrietta Leavitt “one of the most important women ever to touch astronomy,” and another close associate said she had the “best mind at the Harvard Observatory.” Henrietta Leaveitt's story will inspire young women and aspiring scientists of all kinds and includes additional information about the solar system and astronomy.

    It was the first trip across an engineering marvel that had taken nearly fourteen years to construct. The woman's husband was the chief engineer, and he knew all about the dangerous new technique involved. The woman insisted she learn as well. When he fell ill mid-construction, her knowledge came in handy. She supervised every aspect of the project while he was bedridden, and she continued to learn about things only men were supposed to know:math,science,engineering.Women weren't supposed to be engineers. But this woman insisted she could do it all, and her hard work helped to create one of the most iconic landmarks in the world.

    But in every corner of the world this age-old custom is rapidly changing. From increased trade between countries to the expansion of global food corporations like Kraft and Nestlé, current events are having a tremendous impact on our eating habits. Chances are your supermarket is stocking a variety of international foods, and American fast food chains like McDonald’s and Kentucky Fried Chicken are popping up all over the planet. For the first time in history, more people are overfed than underfed. And while some people still have barely enough to eat, others overeat to the point of illness. To find out how mealtime is changing in real homes, authors Peter Menzel and Faith D’Aluisio visited families around the world to observe and photograph what they eat during the course of one week. They joined parents while they shopped at mega grocery stores and outdoor markets, and participated in a feast where a single goat was shared among many families. They watched moms making dinner in kitchens and over cooking fires, and they sat down to eat with twenty-five families in twenty-one countries--if you’re keeping track, that’s about 525 meals! The foods dished up ranged from hunted seal and spit-roasted guinea pig to U.N.-rationed grains and gallons of Coca-Cola. As Peter and Faith ate and talked with families, they learned firsthand about food consumption around the world and its corresponding causes and effects. The resulting family portraits offer a fascinating glimpse into the cultural similarities and differences served on dinner plates around the globe.
