Let’s Begin…

How do we see things too small to be detected by the human eye? What about things inside our own bodies? At TEDYouth 2012, Dee Breger uses a scanning electron microscope to give us a glimpse of images including blood clots, thyroid glands, and lungs with pneumonia.

Here's the intro from Dee Breger's website: Welcome to the remarkable microworld, as seen through the scanning electron microscope (SEM). These images are real photographs of things too small to see with our eyes, or even, in many cases, with the familiar optical microscope. I hope you enjoy your journey - especially through the gallery section - and I look forward to hearing from you!Scanning electron microscopes lord lots of advantages over optical microscopes, but they still can't produce color images. One way to add color is to use photo-processing software. More recently, however, scientists have developed an electron microscope with the ability to detect energy signatures emitted during the magnification process. This information allows the microscope to assign colors to different elements, such as titanium and manganese, depending on the energy signatures they emit. With this technology, researchers can determine precisely where one material ends and another begins, all in glorious color.Willard Wigan tells the story of how a difficult and lonely childhood drove him to discover his unique ability -- to create art so tiny that it can't be seen with the naked eye. His slideshow of figures, as seen through a microscope, can only be described as mind-boggling.Dee Breger's art invites us to know about the body in a unique and submicroscopic way. However, it's also important to know about the parts of our body we can see with the naked eye. Check out these body maps.Dee Breger photographs some of the smallest parts of the human body. But are those the smallest particles we know about? Find out here.

Obviously, they allow Dee Breger to make her beautiful photos, but what other uses do they have?
