- 3-D Crystal Structures
3D crystal structures in VRML may be generated from a variety of standard
crystallographic formats using xtal-3d. Contents: ILL's Gallery of interactive
3D crystal structures, Molecular sieve crystal structure examples in VRML,
xtal-3d for WWW to visualise your own 3D crystal structures, Zeolite and
molecular sieve database of crystal structures in VRML, Superconductor
database of crystal structures in VRML, ICSD for WWW search for and display
inorganic structures and their powder patterns.
- Astr2100 Descriptive
Astronomy Virtual Reality models of the Solar System. Orbits of the
planets drawn and animated to scale. Uses VRML.
- Dramatic Physics
Demonstrations These are the demonstrations from "How Does A Thing
Like That Work?", an entertaining, partially interactive physics show
of visual and dramatic demonstrations from an introductory physics course.
Demonstrations of solid mechanics, fluid mechanics, thermodynamics, electricity
and atmospheric physics are used. The show lasts a microcentury and about
25 fast paced demonstrations are performed. It promotes interest in science
and further discussion.
- Entertaining
Science from LASSP at Cornell University Cool demonstrations of the
research done at The Laboratory of Atomic and Solid State Physics at Cornell
University. Topics include: about hysteresis, quasicrystals, coarsening,
naonoscale pits and bumps, martensites and tweed, pattern formation, polymers
and order parameters, broken symmetry, and topology.
- Introduction
to the Electron Beam Ion Trap project at NIST The electron beam ion
trap (EBIT) allows physicists to create and study an unusual form of matter
which is in an exteme state of ionization. The matter is confined by a
superconducting electromagnetic bottle. The matter is hotter than the sun,
and its internal ionization state is even more energetic. When this matter
is allowed to come in contact with ordinary matter, or even to interact
with the structure of the quantum electrodynamic vacuum itself, strange
things happen.
- Kepler
motion Java applet Initial condition of the "virtual star"
is represented by an arrow. It can be Draged to change the initial position
and initial velocity. Parameters ( total energy, gravitation potential,
effective potential, semimajor axis ...) are viewed graphically. The period
is calculated in real time unit. (Fu-Kwun Hwang)

power plant (java applet) Check how well you can maintain a nuclear
power plant!

Holes, Gas surrounding a galaxy cluster, Slices of a 3-D Teukolsky Wave
Evolution.
- Numerical Relativity
Exhibitions This page includes various exhibits about calculations,
computers, virtual reality, the history of science, and much more related
to general relativity.
Keywords: Black holes, Einstein, Expanding universe.

- Optics and
Lenses (Java Applet) Java Applet by Fu-Kwun Hwang that demonstrates
properties of lenses. An object or the lense can be dragged and dropped
and the focus length of the lense can be varied. Real and virtual images,
parameters and traces are viewed graphically.
- Pendulum
experiment java applet Do a pendulum experiment with mouse(click/drag:to
change its initial conditions-- length of the pendulum, initial position,
gravitational field strength). Parameters (gravitational field and its
components, kinetic energy, potential energy, velocity ...) are viewed
graphically or displayed with text(length, angle, half period...). A period-initial
angle plot is generated automatically, just click/drag the mouse and wait.
Try and play with it to find out more features. (Fu-Kwun Hwang)
- Randomwalk
Applet which illustrates the effect of a randomwalk (the average distance
from the startpoint is proportional to the squareroot of the number of
steps) extended with some historical facts.
- Reaction
time measurement/ car animations applet Would you like to measure your
reation time? Would you like to estimate how fast you can drive on the
highway. You can change the initial velocity of the car and the friction
coefficient of the tires. You can measure your reaction time and estimate
how far you should keep your car away from others on the highway.(Fu-Kwun
Hwang)

to make available an on-line source of information and pictures used for
preparing and performing undergraduate lecture demonstrations at the University
of California Physics Department at Berkeley. This site deals with demonstrations
for the subjects of: Mechanics, Waves, The Properties of Heat and Matter,
Electricity and Magnetism, Optics, Modern and Contemporary Physics, Astronomy
and Perception.

gas law and the piston Another nice and instructive applet from the
Virtual Lab at the University of Oregon. Demonstrates the ideal gas law.
- Vibration and Waves:
Demonstrations and Animations Animations which illustrate some important
phenomena associated with wave behavior, including simple harmonic oscillation
(mass-spring and pendulum); waves on strings; particle motion in sound,
water, and Rayleigh waves; sound radiation from simple sources; Doppler
effect; superposition; interference; single and double slit patterns; reflection
and refraction; lenses and mirrors; and the wave behavior of particles.
