It is important to understand and be able to compare the size of things we are studying. Other things are so far away that a powerful telescope must be used in order to see them. Some phenomena that scientists want to observe are so tiny that they need a magnifying glass, or even a microscope. Scientists examine things in particular ways using a combination of very sophisticated equipment, everyday instruments, and many unlikely tools. For example, compare the size of the Earth to the size of a plant cell, which is a trillion times smaller :Įarth = 12.76 x 10 +6 = 12,760,000 meters wide Exponential notation is a convenient way for scientists to write very large or very small numbers. On the lower left is the same number written in powers of ten, or exponential notation. The number that appears on the lower right just below each image is the size of the object in the picture. Notice how each picture is actually an image of something that is 10 times bigger or smaller than the one preceding or following it. Click on the Auto button to return to the Automatic mode. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. View the Milky Way at 10 million light years from the Earth. POWERS OF TEN © 1977 EAMES OFFICE LLC (Expressions: Science, Optics and You - Secret Worlds: The Universe Within - Interactive Flash Tutorial In 1998, "Powers of Ten" was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". ![]() ![]() Both adaptations, film and book, follow the form of the Boeke original, adding color and photography to the black and white drawings employed by Boeke in his seminal work. The film is an adaptation of the 1957 book Cosmic View by Kees Boeke, and more recently is the basis of a new book version. ![]() The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). Powers of Ten is a 1968 American documentary short film written and directed by Ray Eames and her husband, Charles Eames, rereleased in 1977. Our journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell. Returning to Earth with breathtaking speed, we move inward- into the hand of the sleeping picnicker - with ten times more magnification every ten seconds. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only as a speck of light among many others. Starting at a picnic by the lakeside in Chicago, this famous film transports us to the outer edges of the universe. Powers of Ten takes us on an adventure in magnitudes.
