Science has been responsible for some of our greatest triumphs and tragedies. "Men love to wonder, and that is the seed of our science," wrote Emerson. Some of these wonderings have led to the diesel engine, the telescope and the atom bomb, others to quantum mechanics and evolutionary theory. Who are the major players in the history of science? Everyone knows about Darwin and Einstein, but many more women and men have wondered about the world and made major contributions to the way we live now.
Medical Body Scans The human body is always breaking down, but one perk of living in the 21st century is our access to cutting-edge diagnostic techniques. Medical body imaging such as MRI's, X-rays, 3D CT scans, ultrasounds and nuclear bone scans -- among other techniques -- have transformed the way we see and heal the body. It is now a simple matter to step inside the human brain or look into someone's heart! Though originally in black and white, such medical scans can be color-enhanced to make it easy to identify parts of the image. Colors bring the scans to life, highlighting the areas of interest, such as the location of a tumor or fracture.
