Secret Worlds: The Universe Within
Today's web page under the auspices of Florida State University and the
National High Magnetic Field Laboratory's Optical Microscopy division
offers an interesting java presentation to illuminate the macro and micro
worlds. Gentle Subscribers will discover a startling perspective, beginning
in the far reaches of space to the tiniest subatomic particle.
"Soar through space starting at 10 million light years away from the Milky
Way down through to a single proton in Florida in decreasing orders of
magnitude (powers of ten). This tutorial explores the use of exponential
notation to understand and compare the size of things in our world and the
universe, and provides a glimpse of the duality between the macroworld
around us and the hidden microworld within." - from the website
After its initial run, the visual java demonstration can be used to work
"backwards" from closest to most distant. A brief scientific commentary
accompanies the presentation as well further links to additional
information on the relative sizes of things.
