Underwood, a former high-level executive with Enterprise Rent-a-Car, chronicles the remarkable transformation of a company that grew from a small leasing operation to the largest and most profitable car rental company in the world.

I hope this book will prove useful to all who read it. When you examine a life closely, the positive events clearly outweigh the negative ones. I want to share my story primarily with my children, grand-children and great-grand-children. My journey is a part of their history. This is a story of a “negro” as we were called at the time, brought up in poverty and motivated by the desire to make my parents proud of me and to attempt to reach my full potential in life as a citizen of the United States. My life will be divided into three major eras. The period from my birth in 1929 until 1948 when I went into the military, the twenty years I served on active duty in the United States Navy until 1968 and remained in the reserves until 1978, and the period of my civilian employment with a major defense contractor until I retired in 1991 and life in my retirement years.

In The Demon Under the Microscope, Thomas Hager chronicles the dramatic history of sulfa, the first antibiotic and the drug that shaped modern medicine. The Nazis discovered it. The Allies won the war with it. It conquered diseases, changed laws, and single-handedly launched the era of antibiotics. Sulfa saved millions of lives—among them those of Winston Churchill and Franklin Delano Roosevelt Jr.—but its real effects are even more far reaching. Sulfa changed the way new drugs were developed, approved, and sold; transformed the way doctors treated patients; and ushered in the era of modern medicine. The very concept that chemicals created in a lab could cure disease revolutionized medicine, taking it from the treatment of symptoms and discomfort to the eradication of the root cause of illness. A strange and colorful story, The Demon Under the Microscope illuminates the vivid characters, corporate strategy, individual idealism, careful planning, lucky breaks, cynicism, heroism, greed, hard work, and the central (though mistaken) idea that brought sulfa to the world. This is a fascinating scientific tale with all the excitement and intrigue of a great suspense novel.

Our understanding of disease and the powers of medicine today are unparalleled, and their documentation has increased signficantly. Science is Beautiful collects the most fascinating microscopic photographs of our diseases along with the medicines we use to treat them. These photographs are profoundly fascinating – and also beautiful. Featured are some of the most illuminating microscopic images of bacteria, viruses and cancers ever captured, now made possible by electron micrograph technology. Potentially fatal diseases such as cancer and Ebola are included, and minor complaints such as Staphylococcus bacteria and dental plaque are shown for their surprising beauty. Other photographs reveal what human cells look like when suffering from Alzheimer's, from osteoporosis, or from HIV. It also uncovers some diseases specific to animals. But there are also dazzling images of the crystals, powders and potions that we take to cure ourselves, including magnified versions of aspirin, insulin, morphine and caffeine. This collection of images, as beautiful as any artwork, can be enjoyed purely as a visual voyage but also as a way to understand more of the science behind the image, whether it's the work of a meningitis virus, our chromosomes in a cancer cell or the breakdown of painkillers. Each image includes the scale of the photography as well as the scientific details in layman's terms.

Discusses, from a working mathematician's point of view, the mystery of mathematical intuition: Why are certain mathematical concepts more intuitive than others? And to what extent does the 'small scale' structure of mathematical concepts and algorithms reflect the workings of the human brain?

Our bodies are amazing. The microscopic elements of the human body are profoundly fascinating – and also beautiful. We unearth some of the most wonderful microscopic images of the human body ever created, now made possible by technology. We get to see the wonder of our brains, our cells, our veins, our hormones, even our diseases and the medicines to treat us. The images are as beautiful as any art. This stunning collection of images can be enjoyed purely as a visual voyage but also as a way to understand more of the science behind the image. Whether it's the work of a white blood cell, the power of human hormones, the tiny hairs on our arms, the movement of human cancer cells, the jagged edges of caffeine crystals, or the wonderful shapes of nerve cells, the powerful images will draw you into discovering more about the human body. Each image will include the scale of the photography as well as the scientific details in layman's terms.
