Electromagnetic
Spectrum
"We may think that radio waves are completely different physical objects or
events than gamma-rays. They are produced in very different ways, and we detect
them in different ways. But are they really different things? The answer is
'no'. Radio waves, visible radiation, X-rays, and all the other parts of the
electromagnetic spectrum are fundamentally the same thing."[ Quote from Site]
Interactive
Java Tutorials
Java Applets relating to many electronic and physics topics.
The Virtual Laboratory
Lots of applets. Must about physics but some about electronics. Great sites
lots of great stuff.
Introduction to Neural Networks.
"Neural networks are a new method of programming computers. They
are exceptionally good at performing pattern recognition and other tasks that
are very difficult to program using conventional techniques. Programs that employ
neural nets are also capable of learning on their own and adapting to changing
conditions."[ Quote from Site]
Electron
Microscope
"A scanning electron microscope uses a different principle.
Like a rapid-fire BB gun, it scans electrons across the target which reflect
onto a fluorescent screen where the image is captured by a camera and enlarged.
Electrons are much smaller than atoms, so a scanning electron microscope paints
a razor-sharp image of the target. This is useful for mapping details of objects
that light microscopes can see. The downside is that the picture has no true
colors, just black and white."
X-ray
optics and microscopy at Stony Brook
"Welcome to the x-ray optics and microscopy group at Stony Brook.
We use coherent soft x rays for optics experiments. Much of our effort is
directed towards using Fresnel zone plates to produce the smallest focused spot
of electromagnetic waves of any wavelength, and exploiting that microfocused
beam for studies of biological and materials science specimens."[ Quote from Site]
Dennis
Kunkel's Microscopy
Great pictures taken through an Electron Microscope. Pictures are Colorized.
Impedance
Calculators- resistive, inductive, capacitive, and resonant.
"These calculators have been devised by an experienced electronics
engineer, and made available to the world at no charge." [ Quote from Site]

Electricity
and Magnetism ...
"In this chapter we will discuss phenomena associated with electricity and
magnetism. Although these are two apparently distinct topics, we shall see that
there actually is a deep connection between them."[ Quote from Site]
Has a good interactive section on Basic Electronics
INTRODUCTION
TO POWER ELECTRONICS
"Power electronics refers to control and conversion of
electrical power by power semiconductor devices wherein these devices operate as
switches. Advent of silicon-controlled rectifiers, abbreviated as SCRs, led to
the development of a new area of application called the power electronics. Prior
to the introduction of SCRs, mercury-arc rectifiers were used for controlling
electrical power, but such rectifier circuits were part of industrial
electronics and the scope for applications of mercury-arc rectifiers was
limited. Once the SCRs were available, the application area spread to many
fields such as drives, power supplies, aviation electronics, high frequency
inverters and power electronics originated."[ Quote from Site]
Robot Online
"You can command Xavier anytime, and see your commands carried out live
when it is online, which is usually weekdays 2-4pm EST (19:00-21:00 GMT)."

"In this report, several different types of AM radio receivers will be examined. The report will expand on the material covered in ELEC352 to combine background theory with practical radio design. Most of the common receiver designs will be investigated including the simple crystal set, TRF receivers, reflex receivers, regenerative receivers, and the Superhet. The principals used in circuit design will also be covered in some detail. This will be used as a guide in the design and construction of a TRF receiver. A practical laboratory experiment has also been included. [ Quote from Site]" |

troubleshooting and JAVA circuit simulations with fault insertion.
CMOS
JAVA Gate Demonstrations
"This page demonstrates how CMOS transistors and basic gates work. It is
intended for our computer science undergraduate students. The applets were
written as a test and working demonstration for Java/Hotjava."
Electrons
- Edison Effect
"One clue comes from the "Edison effect," discovered by
Thomas Alva Edison. Imagine a glass bulb from which air has been pumped, until
hardly any of it remains. In one end we embed a metal coil of wire (like that of
a flashlight bulb) in the other a metal plate, as drawn. Connect now a battery
between the coil and the plate, so that the former is negative and the latter is
positive."
A
look Inside the Atom
"amidst glowing glass tubes and the hum of electricity, the British
physicist J.J. Thomson was venturing into the interior of the atom. At the
Cavendish Laboratory at Cambridge University, Thomson was experimenting with
currents of electricity inside empty glass tubes. He was investigating a
long-standing puzzle known as "cathode rays." His experiments prompted
him to make a bold proposal: these mysterious rays are streams of particles much
smaller than atoms, they are in fact minuscule pieces of atoms. He called these
particles "corpuscles," and suggested that they might make up all of
the matter in atoms. It was startling to imagine a particle residing inside
the atom--most people thought that the atom was indivisible, the most
fundamental unit of matter." From A look Inside the Atom.
