Dimensions Home A film for a wide audience! Nine chapters, two hours of maths, that take you gradually up to the fourth dimension. Mathematical vertigo guaranteed! Background information on every chapter: see "Details". Click on the image on the left to watch the trailer ! Disappearing Glass Rods: Reflection, Refraction & Light Science Activity Disappearing Glass Rods You can make glass objects disappear. Glass objects are visible because they reflect some of the light that shines on them and bend or refract the light that shines through them.

Optics For Kids - The Optical Society: Exploring the Science of Light Remote controls for devices like televisions, cable boxes, and DVD players typically operate in the infrared. On the front of the remote is a light emitting diode (LED) that produces light in the infrared region. The light flashes quickly to produce a sequenced pattern, which the device being controlled then reads and interprets as a command. Required Materials TV/cable/DVD remote control Webcam or camera phone Activity Directions

Special Relativity Special Relativity These pages are ok as far as they go, but they are missing the planned highlight, to show you what things actually look like when you travel at near the speed of light. I hope to have the opportunity to develop these pages further as time permits. Can you make a rainbow disappear? What you need: A colour print out of the colour wheel above Glue Cardboard Scissors Pencil How you do it: Usenet Physics FAQ Version Date: March 2013 This list of answers to frequently asked questions in physics was created by Scott Chase in 1992. Its purpose was to provide good answers to questions that had been discussed often in the sci.physics and related Internet news groups. The articles in this FAQ are based on those discussions and on information from good reference sources.

Fascinating Friction! Summary Students use wood, wax paper and oil to investigate the importance of lubrication between materials and to understand the concept of friction. Using wax paper and oil placed between pieces of wood, the function of lubricants between materials is illustrated. Students extend their understanding of friction to bones and joints in the skeletal system and become aware of what engineers can do to help reduce friction in the human body as well as in machines. Engineering Connection HPS 0410 Einstein for Everyone Title page, Preface and Table of Contents for Einstein for Everyone Introduction: the Questions Special Relativity Special Relativity: the Principles Stuff for Teachers We have many different classroom-tested activities on a variety of different topics that you can download and use. All of these activities use easy-to-find (and inexpensive!) pieces, as you'd expect from the Little Shop of Physics.

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.
