Sullivan says this, her first book, is aimed at giving students of all ages a taste of the diversity of careers in which science is used. The book profiles 34 people who use science in their daily work and provides readers with a glimpse of what it is like to actually apply science in the real world. The careers range from the expected — high school science teacher, microbiologist, and forensics technician — to the perhaps unexpected — firefighter, landscape architect, and historical archaeologist — to the adventurous — astronaut, deep-cave explorer, and oceanographer — to the offbeat — roller coaster designer, perfumer, and sports biomechanist.
