Physics Flash Animations

clipped by: pokkets
clipper's remarks: The top links, go to the list of 90 Flash Animations with 'view' links. When the view link is pressed. an animation opens up a new tab There are a few direct links to an animation, at the bottom of the clip

We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window.

The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from http://www.macromedia.com/. The categories are:

Chaos
Classical Mechanics
Electricity and Magnetism
Micrometer Caliper
Miscellaneous
Nuclear
Optics
Oscilloscope
Quantum Mechanics
Relativity
Sound Waves
Vectors
Waves

In addition, I have prepared a small tutorial in using Flash to do Physics animations. It contains screen shots and embedded Flash animations, so the file size is a 173k. You may view it in a separate window at http://faraday.physics.utoronto.ca/PVB/Harrison/Flash/Tutorial/FlashPhysics.html.

The Problem of Time (from "Time May Not Exist")

The possibility that time may not exist is known among physicists as the “problem of time.” It may be the biggest, but it is far from the only temporal conundrum. Vying for second place is this strange fact: The laws of physics don’t explain why time always points to the future. All the laws—whether Newton’s, Einstein’s, or the quirky quantum rules—would work equally well if time ran backward. As far as we can tell, though, time is a one-way process; it never reverses, even though no laws restrict it.

in order to specify what happens to a system, you not only have to specify the physical laws, but you have to specify some initial or final condition.”

The mother of all initial conditions, Lloyd says, was the Big Bang.

Although the laws of physics themselves don’t provide for an arrow of time, the ongoing expansion of the universe does.

the expansion of the universe, which may be the origin of what we think of as the ceaseless forward march of time

Man loses top of his head in brain operation; sues doctors

A German court has awarded 3,000 euros ($4,100) in damages to a man who had to have the top of his skull replaced with plastic because of a faulty hospital fridge.

Doctors removed the top of the man’s head and put it in cold storage while they operated on his brain

Because the refrigerator was defective, the section of skull was not kept cool enough and could not be reattached. Doctors replaced the bone with a plastic prosthesis.

The man sought compensation of at least 20,000 euros on the grounds that the prosthesis caused him headaches

the court found that the operation had caused the man’s discomfort, not the loss of the top of his skull.

Compensation of 3,000 euros was “appropriate and sufficient

Sex in the syllabus?

Colleges are getting serious about porn studies, but should professors show or just tell?

With classwork like this, who needs to play? Undergraduates taking Cyberporn and Society at the State University of New York at Buffalo survey Internet porn sites. At New York University, assignments for Anthropology of the Unconscious include discussing X-rated Japanese comic books. And in Cinema and the Sex Act at the University of California, Berkeley, undergrads are required to view clips from Hollywood NC-17 releases like Showgirls and underground stag reels. It's called the porn curriculum, and it's quietly taking root in the ivory tower. A small but growing number of scholars are probing the...
