Resena: In science the credit goes to the man who convinces the world, not to the man to whom the idea first occurs.
—Francis Darwin (1848–1925)
From the very first moment humans appeared on the planet, we have attempted to understand and explain the world around us. The most insatiably curious among us often have become scientists. The scientists discussed in this book have shaped humankind s knowledge and laid the foundation for virtually every scientific discipline, from basic biology to black holes. Some of these individuals were inclined to ponder questions about what was contained within the human
body, while others were intrigued by celestial bodies. Their collective vision has been concentrated enough to examine microscopic particles and broad enough to unlock tremendous universal marvels such as gravity, relativity—even the nature of life itself. Acknowledgement of their importance comes from a variety of knowledgeable and well-respected sources; luminaries such as Isaac Asimov and noted biochemist Marcel Florkin have written biographies
contained herein.
The influence wielded by the profiled men and women within the realm of scientific discovery becomes readily apparent as the reader delves deeper into each individual s life and contributions to his or her chosen field. Oftentimes, more than one field has been the beneficiary of these brilliant minds. Many early scientists studied several different branches of science during their lifetimes. Indeed, as the founder of formal logic and the study of chemistry, biology,
physics, zoology, botany, psychology, history, and literary theory in the Middle Ages, Aristotle is considered one of the greatest thinkers in history. Breakthroughs in the medical sciences have been numerous and extremely valuable. Study in this discipline begins with a contemporary of Aristotle s named Hippocrates, who is commonly regarded as the “father of medicine.” Perhaps Hippocrates’ most enduring legacy to the field is the Hippocratic Oath, the ethical code that doctors still abide by today. By taking the Hippocratic
Oath, doctors pledge to Asclepius, the Greco-Roman god of medicine, that to the best of their knowledge and abilities, they will prescribe the best course of medical care for
their patients. They also promise to, above all, cause no harm to any patient.
The Greeks were not the only ones studying medicine. The Muslim scholar Avicenna also advanced the discipline by writing one of the most influential medical texts in history, The Canon of Medicine. Avicenna also produced an encyclopedic volume describing Aristotle’s
philosophic and scientific thoughts about logic, biology, psychology, geometry, astronomy, music, and metaphysics. This hefty tome was called the Kitab al-shifa (“Book of Healing”). About 450 years later, a German-Swiss physician named Philippus Aureolus Theophrastus Bombastus Von Hohenheim, or Paracelsus, once again advanced
medical science by integrating medicine with chemistry and linking specific diseases to medications that could treat them.
The Renaissance period brought to light the scientific genius of painter and sculptor Leonardo da Vinci. His drawings of presciently detailed flying machines preceded the advent of human flight by more than 300 years. What s more, da Vinci s drawings of the human anatomy structure not only illuminated many of the body s features and
functions, they also laid the foundation for modern scientific
illustration.
Anatomical drawings were also the purview of Flemish physician Andreas Vesalius. Unlike da Vinci s illustrations, which were mainly for his own artistic education, Vesalius incorporated his sketches and the explanations of them into the first anatomy textbook. His observations of human anatomy also helped to advance physiology, the
study of the way the body functions.
Other physicians took their investigation of anatomy
off the page and onto the operating table. Ancient Greek
physician Galen of Pergamum greatly influenced the study
of medicine by performing countless autopsies on monkeys,
pigs, sheep, and goats. His observations allowed him
to ascertain the functions of the nervous system and note
the difference between arteries and veins. Galen was also
able to dispel the notion that arteries carry air, an idea that
had persisted for 400 years.
Centuries later, in the 1600s, Englishman William
Harvey built on Galen’s theories and observations, and
helped lay the foundation for modern physiology with his
numerous animal dissections. As a result of his work,
Harvey was the first person to describe the function of the
circulatory system, providing evidence that veins and
arteries had separate and distinct functions. Before his
realization that the heart acts as a pump that keeps blood
flowing throughout the body, people thought that constrictions
of the blood vessels caused the blood to move.
Other groundbreaking scientists have relied on observations
outside the body. A gifted Dutch scientist and lens
grinder named Antonie van Leeuwenhoek refined the
main tool of his trade, the microscope, which allowed him
to become the first person to observe tiny microbes.
Leeuwenhoek’s observations helped build the framework
for bacteriology and protozoology..............................................................
