What is a brainworm? The word evokes possibilities; is it perhaps like an earthworm, tilling the soil and making it more fertile? Or perhaps a parasite, harvesting from an organism without care for its host's health and well-being? The brainworm could well be a new revelation: what mysteries might be contained within a book entitled Brainworms...and Other Surprises at the Margins of the Impossible? Brainworms, a series of essays, reveals the rumblings and grumblings of an unsatiable mind confronted with infinite possibilities. Ranging from topics in clinical medicine through to its underlying molecular biology and to radiation sciences and astronomy, Brainworms contains insight and wonder about the world we live in. Chronic curiosity and scientific investigation combine to reveal often surprising connections between such unlikely combinations as Galileo's boredom, chaos, and mental health. Or consider the relationship of fifteenth-century troubadours to modern treatment of breast cancer. Perhaps the ties among honey bees, space exploration, and epigenetics are more to your interest. Possibly, you are more intrigued by linkages of sheep to muscle memory and the microbiome. Skillfully written, in a style reminiscent of nineteenth century writers and thinkers, Brainworms is an eclectic collection of short essays along a broad topical front that was inspired by the author's observations of life in a diverse set of scientific fields. This delightful volume documents the unexpected avenues that our brains can take in their quest to explain and appreciate the grandeur of the universe and the exciting discoveries within it. Totally unpredictable and always captivating, Brainworms offers thought-provoking insight and stimulation to the scientific and unscientific alike.
