Scientific digital imaging systems have revolutionized many branches of science and medicine. Precision imaging, at the micro and macro level, now allow us to look farther and deeper into the world around us than we have ever have before. Debates in fields as diverse as philosophy and physics are being answered, questions that have puzzled mankind for centuries. Digital imagining is revolutionizing the sciences, including medicine, and our understanding of the world we live in
Micro imagining has allowed the smallest things to leap into focus. Cellular studies in biology and medicine can now be captured digitally and recorded for analysis. The ability to peer into the underlying structure of cells has opened the door to scientific discovery of how cells split, grow and die.

Engineers working with underwater cameras spied under an arctic glacier and were surprised to find a submerged range of mountains that possibly no one had suspected existed. Further exploration has continued on Antarctica and in places on Earth where no one suspected life could survive. With super sensitive cameras, scientists can now record animals in the wild using motion detectors, creating images that have not been captured before for studies about wildlife conservation.
From a macro point of view, astrophysics use digital images and sophisticated computer applications to look at the night sky with new eyes. With the use of advanced telescopes, they are unraveling the mysteries of the faraway stars. They have discovered light from the Big Bang, now thirteen billion light years away from Earth. Microwave radiation and gamma waves are also possible to view with digital images, though they exist out of the spectrum of light that the human eye can see.
With these amazing images, scientists can determine if galaxies are moving toward us or away by the red or blue shift in the light. This has increased our understanding that we live in an expanding universe, not a static one and provided insight into the nature of gravity on a large scale.
For centuries, philosophers debated the nature of consciousness. Now, science is chiming in as neurologists have the ability to watch the brain in action. The separation, made by Rene Descartes in his book Meditations in 1641, for example of the mind from the brain, with contact occurring via the pineal gland is not holding up well to scientific scrutiny.
Doctors now use digital imagining to examine their patients. This is used by surgeons to determine when to operate. Neonatal imagining can help doctors diagnose medical conditions while a child is still in the uterus. Dentists also use sophisticated images to evaluate the health of the bones for the jaw.
So, from outer galaxies to the chair in the dentist office, Scientific Digital Imaging is changing the way science understands the universe around us. Life can now be examined at a cellular level, contributing to our understanding of medicine and genetics. The inaccessible place on the planet have come into view. With advances continuing, this may be just the tip of the iceberg of discovery.
