Physics Flash Animations
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 In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. These animations were written by David M.
The Transistor
Lists of Nobel Prizes and Laureates The Transistor Play the Transistor Recycler Game About the game A transistor is made of a solid piece of a semiconductor material and either used as switches, to turn electronic signals on or off – or, as amplifiers.

Gummy Bear Fossils | Mrs. Lesser's Classroom
Before we left for our three-day weekend, we discussed fossils in science class. We learned that fossils can be either remains from dead animals and plants or imprints left behind after those remains have been covered by sediment and layers of earth. We also learned that fossil fuels are made when heat and pressure are added to the fossils below the earth’s surface and the fossils become petroleum that can be extracted by drilling miles into the earth’s surface. To demonstrate this process, we used white bread as the layer of white sand on the ocean floor. We then placed four gummy bears on the ocean floor to symbolize dead sea life that floats to the bottom of the ocean. Today, we were finally able to take a look at our gummy bear fossils.
10 Tech Concepts You Need to Know for 2010
1. Anthropomimetic Machines No matter how closely a robot resembles a human on the outside, if you crack it open, the jumble of wires is unlikely to bear much resemblance to our insides. A group of European researchers aims to bridge that gap--its robot prototype is anthropomimetic, meaning it mimics the human form. There's a skeleton made of thermoplastic polymer, actuators that correspond to each muscle and kiteline as tendons. The goal is to create a more human-like robot that interacts with and responds to environments the way we do. 2. Yesterday's fuel cells, like those seen here on Spacelab, require a hydrogen infrastructure. Coal is dirty, and fuel cells run on hydrogen--that's the conventional wisdom. 3. 4. Scientists at Caltech have been folding microscopic strands of DNA into interesting shapes for the past few years. 5. (Illustration by Leandro Castelao) 6.

STEM Mom: Footprint Lab: Playing and Designing Methods
In my attempt to do a lab resembling earth science, this week in my middle school science lab, we did a "Footprint and Tracking" lab This allowed me to play with various "fossil" dough recipes, but more about that in a minute. Here is a link to the student lab handout. I wrote the prelab section as a way to get students thinking about evidence and to make sure they understand the difference between observations and inferences. Observations are what we can record about what we see, hear, smell, touch, and taste. (Usually taste doesn't apply.) Inferences are how we interpret our observations. So our list looked like this. The next prelab question asks students, "Is there information missing? The hands-on portion of the lab is intended to allow students to play. Mix all ingredients together, and knead extra flour into the mixture to give it a doughy texture. Because I have happen to have kids shoes, and I knew it would allow the student to use less dough, this was a great option.
The Large Hadron Collider
The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. All the controls for the accelerator, its services and technical infrastructure are housed under one roof at the CERN Control Centre. How many kilometres of cables are there on the LHC?

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. This text owes a lot to many. i i i
