Attention: science teachers and students
I write eBooks that teach electronic fault isolation using simulation and animation. See some examples of my stuff in center column of page 1.
My animations are not simply cute visual aids
but are designed to provide actual performance orientated training for
electronic students. Thirty years of experience as a Field Engineer
(Technician with a degree and passport) and an electronics instructor are behind
these simulations. Check them out yourself; I'm an open book. My
free eBooks are available at Science
The Electron Microscope can achieve useful magnification of almost one million while the light microscope can only achieve 2000.
The greater magnification ability of the electron microscope is due to the shorter wavelenght of electrons (at 100-kev) compared to the wavelenght of light. My Electronics link library contains two links(copies below) on electron microscopes.
From Stephon Hawking Website"I want you to share my excitement at the discoveries, past and present, which have revolutionized the way we think. From the Big Bang to black holes, from dark matter to a possible Big Crunch, our image of the universe today is full of strange sounding ideas, and remarkable truths. The story of how we arrived at this picture is the story of learning to understand what we see."
Stephon Hawking on Wormholes
"Einsteins General Theory of Relativity seems to offer the possibility that we could create and maintain wormholes, little tubes that connect different regions of space-time. If so, we might be able to use them for rapid travel around the galaxy or travel back in time. Of course, we have not see anyone from the future (or have we?) but I discuss a possible explanation for this."
